Description

The invention relates to the field of construction of bicycles, in particular to the development of methods for controlling the rotation and to the design of the node rotation of the bicycle.

A typical bicycle is widely known (see Wikipedia - https://ru.wikipedia.org/wiki/Bicycle), which consists of a vertical frame, a T-shaped handlebar rigidly fastened to the front wheel of the bicycle, while the handlebar with the stand is attached to the bearing part of the frame through the hinge, with the possibility of turning the steering wheel with the rack and with the front wheel around the longitudinal axis of the rack. In addition, the bicycle includes a rear wheel mounted in the rear fork, a saddle (seat) attached to the top of the frame, pedals with cranks, a chain drive and brakes.

At the same time, the left and right parts of the steering wheel are bent symmetrically on the sides relative to the vertical plane of the frame in the form of curved rudder handles, they usually form a single unit with the wheel, with the ability to rotate the entire steering structure, as a whole, around the axis of the specified front wheel strut. In this case, the plane of the front wheel rotates accordingly, and the bicycle rotates along the required trajectory of the necessary curvature (hereinafter, it rotates along the rut).

Disadvantages. The main disadvantage of such a bicycle is the unreliability of the left and right handlebars as a stable support for the hands that carry the weight of the torso of a cyclist. This is due to the possibility of the free rotation of these handles around a common specified axis, which leads to the need for additional control of the cyclist's balance on the bicycle while ensuring stability of movement, depending on the position of the handlebars.

To turn the bike in one direction or another, you need to turn the handle of the steering wheel, namely, move one handle to the cyclist, and the other from him. In addition to the lateral displacement of the torso, in order to maintain balance on the bicycle, it is necessary to deviate forward or backward and turn the body to simultaneously turn the steering wheel and ensure the reliability of the support of the hands on the steering wheel. These actions are accompanied by tension of certain muscle groups, which are rarely used, which often leads to a loss of stability of the bicycle, balance and a fall of the cyclist.

A vehicle is known (see RU patent for invention No. 2147537 dated 02.21.1995, “Method of movement and control of a vehicle and a vehicle for its implementation”).

In this analogue, the vehicle (hereinafter - TC) contains a frame made of front and rear parts, pivotally connected to each other, with the possibility of rotation around a common vertical axis at the junction, two wheel mounts mounted one after the other at the ends of the frame, a saddle located above the vertical axis of the connection of the parts of the frame, this saddle is additionally equipped with a saddle post, one end of which is connected to the upper part of the axis by a hinge, allowing the stand to tilt back and forth in the direction of travel, etc. goy strut end connected to the lower part of the seat by a hinge, the seat is tiltable in a vertical plane passing through the centers of the wheels, with the axle seat is rotatable in a horizontal plane.

In addition, the seatpost has an element for adjusting and fixing its length, and the saddle is pivotally connected to one end of the rod, also having an element for regulating its length and mounted parallel to the rack, the other end of the rod is pivotally connected to the upper part of the axis. In addition, each of the wheel mounts is made in the form of a fork, inside of which a freely rotating wheel or wheeled trolley is located on the axis of the assembly, and the pedal is located outside the fork on the continuation of the assembly axis, with the pedal located on one side of the wheel and on the rear node - with the opposite.

Movement and control of the vehicle is carried out by rolling a person in a walking position or in a sitting position on a saddle mounted on wheels located one after another, which, as indicated above, are connected to each other and to the saddle. The vertical planes of the wheels are rotated by the feet of the user of the vehicle relative to the common vertical axis located between them. Additionally, the rolling is combined with the elements of the walking movement, while each user foot is connected via a pedal to the wheel (one on the right, the other on the left), and control is carried out by turning the legs and transferring the person’s center of gravity. Thus, the rotation of the vehicle in motion can be carried out by rotating the plane of both the front and rear wheels simultaneously or separately relative to the vertical axis and saddle, which ensures the movement of the wheels and the vehicle along the track.

Disadvantages. The TS presented in the analogue solves a different problem compared to the claimed technical solution.

In an analogue, the transmission of the turning force and the control of the rotation is carried out by turning and pressing the feet, and it is also necessary to simultaneously set the vehicle in motion with the feet, which is often inconvenient and poorly feasible. In this case, it is necessary to regularly (or mainly) get up from the saddle, ride while standing and, accordingly, change the balance position. As a result, the user's position relative to the vehicle is highly unstable. In addition, the user's legs are actually attached to the pedals, which is a serious inconvenience for him and can lead to a fall of the user and injury.

With the cantilever design of the pedals and to ensure their correct position relative to the frame, it is necessary to provide the corresponding strength and design characteristics of the pedals to the base, which will greatly complicate and weight the hinge structure of the vehicle.

As a prototype of the bicycle turning assembly of the present invention, a bicycle made by Hans-Ulrich Reimers is adopted - see Erik Wannee's article: “Bikes with a rear steering wheel - WRC” on www .wannee.nl / hpv / abt / ru-index.htm.

The design of the bike is similar to the FlevoBike, but here the saddle is mounted on the front of the frame (rotatable relative to the rear). The pedal drive is carried out on the front wheel, the plane of which coincides with the vertical plane of the front of the frame. In addition, the rotation of the bicycle is controlled by two handles in the form of left and right levers, mounted symmetrically on the sides of the front of the frame under the saddle. Each handle has the ability to rotate around its own axis. The axis of rotation of the handles lie on one straight line, perpendicular to the plane of the front of the frame. Each handle through a crank, hinges and traction is connected on its side with a corresponding shoulder of the rear part of the frame (these shoulders are perpendicular to the plane of this part of the frame), in the vertical plane of which the rear wheel is fixed at the rear.

The turning force of one, for example, the left handle, through the rod is transmitted to the left shoulder of the rear of the frame and rotates the frame in the corresponding direction relative to the front. Accordingly, the planes of the front and rear wheels mutually rotate. As a result, the bike rotates along a rut. In this case, the right lever handle is connected to the left handle through a serial kinematic connection, namely: rotation of the right handle / transmission with the right link / rotation of the right shoulder of the rear frame (as a whole) rotates the left shoulder of the rear frame / transmission with the left link / rotation of the left handle. In this case, the handles rotate in mutually opposite directions.

Disadvantages of the turning unit and the bicycle as a whole.

Due to the location of the axis of rotation of the handle levers below under the seat for the hands and the upper part of the torso of the cyclist, there is no reliable, stable support, which is especially necessary while maintaining balance and stability of movement during sharp turns and accelerations.

With a sharp turn in some certain positions of the cyclist, one of the handles, due to its large size, prevents the cyclist from freely leaning in the right direction to compensate for the strength of the overweight in order to maintain balance.

In addition, the constructive placement of kinematic communication elements in the prototype, such as levers, traction, etc., interferes with the free location of the cyclist when riding a bicycle and in motion.

In addition, due to the peculiarities of this design of the turning unit and the bicycle as a whole, it is impossible (and not supposed) to transform the bicycle: reconfigure the bicycle geometry to the parameters of the cyclist, the destination parameters of the bicycle, sludge and provide the possibility of folding it for transportation and / or storage.

The problem solved by the present invention is to provide a method of transmitting force to control the rotation of the bicycle, as well as the node rotation of the bicycle. As a result of solving the problem, we obtain the following technical result of the invention.

- The proposed node rotation of the bicycle contains two handles mounted on each side on the frame of the bicycle. Moreover, each handle has its own axis of rotation, stationary relative to the frame.

A design feature of the turning unit and the bicycle itself is the use of three-link subassemblies and transmission shafts when transmitting the turning force from the handles to the axis of the corresponding controlled bicycle wheel. This allows with great freedom to choose the location of these handles on the sides symmetrically relative to the plane of the bicycle frame, but mainly, they are placed in front, in a place convenient for supporting the hands of the cyclist. In addition, the shape of each handle allows you to conveniently grab it with your fingers and / or hand, lean and control the rotation of the bike without moving the torso. Thus, for the hands and, accordingly, for the body of the cyclist, there is a reliable fixed support, which together with other support points (saddle, pedals) allows the cyclist, sitting or in a different position, to more freely maintain balance during movement and when turning the bicycle. As a result, the safety of cycling is increased.

- Also, due to the immobility of the axles of the handles, the cyclist, while holding them, can move up, stand, deviate in one direction or another from his stationary state, as he wishes, to reduce the load on the muscles and the overall load as a whole.

- A number of different options have been proposed for transferring the effort of the cyclist and the design of the kinematic connections of the handles of the turning unit to the driven front and / or rear wheel of the bicycle, which allow transmitting the force from the handles to the corresponding wheel support (wheel support) of the bicycle through the transmission shafts in the same way .

- When designing the rotation node of the bicycle, in accordance with the variants of the invention, the developer has the opportunity to apply for kinematic connections as gears: cylindrical, bevel and / or other shapes, and elements of linkage, cable rods, pin drives, and / or slotted wings mounted coaxially on the corresponding handle, on the corresponding axis and / or on the corresponding shaft, as well as helical, hypoid and other types of gears.

- In order to compactly transmit the turning force, it is possible to place the longitudinal elements of the rotation unit (shafts and other longitudinal elements) in the supporting (tubular) elements of the bicycle frame. Such placement will practically hide the design of the turning unit inside the frame of the bicycle, which will allow the cyclist to freely position and move relative to the frame during the movement of the bicycle, without fear of clinging to the elements of the turning unit. Also, ceteris paribus, streamlining will improve and the bicycle’s resistance to airflow during movement will decrease.

- At the same time, to ensure the possibility of transformation of the geometry of the bicycle, the design of the longitudinal elements of the rotation unit and the supporting elements of the bicycle frame can be made in the form of their telescopic connection with the possibility of fixing at a given length. This design feature is necessary for the possible reconfiguration of the bicycle for the parameters of the cyclist, for the destination parameters of the bicycle, as well as for the possibility of folding it during transportation and / or storage.

- This application discusses options for a bicycle with one front and one rear wheel, while the proposed technical solution can also be applied to bicycles with two front and / or two rear wheels.

The specified technical result is achieved in a method of transmitting force to control the rotation of the bicycle, namely, that

during the movement of the bicycle, the cyclist rotates the left and / or right handle of the rotation node of the bicycle around its axis of rotation,

these two handles have separate rotation axes and are fixed on both sides of the bicycle frame,

in order to maintain balance and stability of movement, the cyclist shifts the center of gravity of his and / or bicycle relative to the reference points of the bicycle with the ground,

the design of the rotation node of the bicycle provides for the kinematic connection of these handles with swivel bearings of the front, rear or both wheels through one or more kinematic links, pairs, including in the form of a left and right sequence of links transmitting the turning force from the corresponding handle to turn the support front wheel and / or turning the rear wheel support of the bicycle.

Hereinafter, a bicycle wheel support is understood to mean a stand, fork or feather to which an axle and / or hub of a bicycle wheel is attached. As a result of the rotation of the support of one or another wheel, the plane of this wheel rotates accordingly, providing rotation of the bicycle.

The method differs from analogues in that

in the case of turning the bicycle by turning the front or rear wheel, the cyclist transfers the turning force from these handles to the front or rear wheel support through kinematic links, which are combined into a subnode - a three-link transmission simultaneously from each handle, by direct kinematic connection or through an intermediate kinematic link, to the primary rotation shaft transmitting this force, directly or through one or more secondary kinematic links, to the front wheel support (hereinafter we write - primary th rotation shaft of the front wheel plane), or on the primary rotation shaft that transfers this force, directly or through one or more secondary kinematic links, to the rear wheel support (hereinafter we write - the primary shaft of rotation of the rear wheel plane),

or, in the case of turning the bike by turning the front and rear wheels at the same time (hereinafter, there is one of three options for transferring the turning force of the handles to the wheel supports i, ii, iii):

i) the cyclist transfers the turning force from the indicated handles to both wheels simultaneously through the kinematic links, which are combined into a subnode - a three-link transmission simultaneously from each handle, by direct kinematic link or via an intermediate kinematic link, to the primary rotation shaft of the front wheel plane and, accordingly, further on the support of the front wheel, while also from this shaft, its rotation through another kinematic pair is transmitted to the primary shaft of rotation of the plane of the rear wheel and, accordingly on further to the rear wheel bearing,

ii) the cyclist transfers the turning force from the indicated handles to both wheels simultaneously through the kinematic links, which are combined into a subnode - a three-link transmission simultaneously from each handle, by direct kinematic link or via an intermediate kinematic link, to the primary shaft of rotation of the plane of the rear wheel and, accordingly, further on the support of the rear wheel, while also from this shaft, its rotation through another kinematic pair is transmitted to the primary shaft of rotation of the plane of the front wheel and, accordingly further to the front wheel support,

iii) the cyclist transfers the turning force from these handles to both wheels simultaneously through kinematic links that are combined into a complex subnode: the first three-link transmission transfers the turning force from each handle simultaneously, by direct kinematic link or via an intermediate kinematic link, to the primary shaft of rotation of the front wheel plane and, accordingly, further to the front wheel support, and in parallel the second three-link transmission transmits the turning force simultaneously from each same handle, kinematic connection or through an intermediate kinematic link, on the primary shaft of rotation of the plane of the rear wheel and, accordingly, further on the support of the rear wheel,

(in option iii, the primary rotation shafts of the planes of the front and rear wheels are not directly connected, like a kinematic couple, but are connected indirectly, through the kinematic connection of each shaft with the handles of the bicycle turning unit),

at the same time, each specified handle of the turning unit or part thereof has such a shape, size and is arranged so that the cyclist to transmit the turning force could grab it and turn it around the rotation axis with the fingers and / or brush of the corresponding hand, regardless of rotation or displacement your torso.

In particular, in the method of the handle of the rotation node of the bicycle and their rotation axis are located symmetrically - on the sides relative to the bicycle frame, in front of it.

In particular, in the method, each handle is made in the form of the same tube or rod having a cylindrical or close to cylindrical shape, located symmetrically relative to the vertical plane of the bicycle frame, with the possibility of rotation of each handle around its axis of rotation, coinciding or parallel to the axis of the cylinder.

In particular, in the method, each handle is fixed or the handle itself is a lever or trigger pusher, mainly of the same shape, perpendicular or inclined to the axis of rotation of the handle, located symmetrically relative to the vertical plane of the bicycle frame, with the possibility of turning the lever or pusher together with the handle around the axis turning the handle.

In particular, in the method for turning the bicycle, the cyclist turns the left and right turn handles in opposite directions.

In particular, in the method, the transmission of force from the handles of the rotation unit and the engagement of the corresponding kinematic pairs is carried out using one or more gears, mainly bevel and / or cylindrical, and coaxially mounted on the corresponding handle, corresponding to the axis and / or on the corresponding shaft.

In particular, in the method, the transmission of force from the handles of the rotation unit and the engagement of the corresponding kinematic pairs is carried out using one or more linkage elements, cable rods, pin gears and / or slotted wings mounted coaxially on the corresponding handle, on the corresponding axis and / or corresponding shaft.

The technical result is also achieved in the node rotation of the bicycle, containing

the left and right handle of rotation of the bicycle, which are fixed on both sides to the frame of the bicycle with the possibility of rotation of each handle separately around its own axis, stationary relative to the frame,

and also, mounted on a bicycle frame, a mechanism for transmitting the turning force from each or both handles to the supports of the front, rear or both wheels rotated through a kinematic connection in the form of one or more kinematic links, pairs, including in the form of a left and right link sequence for transmitting the turning force from the corresponding handle to the rotation of the plane of the front wheel and / or to the rotation of the plane of the rear wheel of the bicycle,

while the rotation knobs themselves and elements of the mechanism for transmitting the forces of turning the knobs to rotate the plane of the wheels, including the primary elements of the kinematic links for transmitting the rotation of the knobs to the wheel supports, can mainly be placed and fixed on the frame in front of the bicycle in the area of the usual arrangement of hands the cyclist.

The rotation node of the bicycle differs from analogues in that

in the case of turning the bicycle with the front or rear wheel, the kinematic links of transmitting the turning forces from each of these handles are a constructive combination into a subnode - a three-link transmission simultaneously from each handle, by direct kinematic connection or through an intermediate kinematic link, to the primary shaft of rotation of the front plane wheels and, accordingly, further to the front wheel support or to the primary shaft of rotation of the plane of the rear wheel and, accordingly, further to the rear support about the wheels

or, in the case of turning the bike with the front and rear wheels at the same time (hereinafter there is one of three options for transferring the turning force of the handles to the wheel supports i, ii, iii):

i) the kinematic links of the transmission of the effort of rotation from each of these handles are a constructive combination into a subassembly - a three-link transmission simultaneously from each handle, by direct kinematic connection or via an intermediate kinematic link, to the primary shaft of rotation of the plane of the front wheel and, accordingly, further to the front wheel support wheels, while also from this shaft, its rotation through another kinematic pair is transmitted to the primary shaft of rotation of the plane of the rear wheel and, accordingly, further and the rear wheel support,

ii) the kinematic links of the transmission of the effort of rotation from each of these handles are a constructive association into a subassembly - a three-link transmission simultaneously from each handle, by direct kinematic connection or through an intermediate kinematic link, to the primary shaft of rotation of the plane of the rear wheel and, accordingly, further to the rear support wheels, while also from this shaft, its rotation through another kinematic pair is transmitted to the primary shaft of rotation of the plane of the front wheel and, accordingly, further to front wheel support

iii) the kinematic links of the transmission of the effort of rotation from each of these handles are a constructive combination into a complex subassembly: the first three-link transmission transmits the effort of rotation simultaneously from each handle, by direct kinematic link or via an intermediate kinematic link, to the primary shaft of rotation of the plane of the front wheel and, accordingly , further to the front wheel support, and in parallel the second three-link gear transmits the turning force simultaneously from each of the same handles, directly th kinematic bond or through an intermediate kinematic link, the input shaft of the rear wheel rotation plane and, therefore, further to the rear wheel support,

each said handle of the rotation unit has such a shape, size, and is arranged so that the cyclist can transmit it and have the ability to clasp it and turn it in the right direction around its axis with the fingers and / or brush of the corresponding hand, regardless of the rotation or displacement of its torso,

each handle is preferably made in the form of the same tube or rod having a cylindrical or close to cylindrical shape, located symmetrically on the sides relative to the vertical plane of the bicycle frame, with the possibility of rotation of each handle around its axis of rotation, coinciding or parallel to the axis of the cylinder,

and / or each handle is fixed or the handle itself is a lever or trigger pusher, mainly of the same shape, perpendicular or inclined to the axis of rotation of the handle, the handles are located symmetrically relative to the vertical plane of the bicycle frame, with the possibility of turning the lever or pusher together with the handle around handle rotation axis,

while also for transmitting the turning force, the left and right handles of the bicycle turning unit must have the constructive ability to turn in opposite directions,

moreover, the transmission of the turning force from the handles and the engagement of the kinematic pairs can be carried out mainly using, among other things, one or more gears, mainly bevel and / or cylindrical, and coaxially mounted on the corresponding handle, on the corresponding axis and / or on the corresponding shaft ,

and / or using one or more linkage elements, cable rods, pin drives and / or slotted wings mounted coaxially on the corresponding handle, on the corresponding axis and / or on the corresponding shaft,

moreover, inside one or more supporting tubular elements of the bicycle frame, it is possible to place the primary (e) shaft (s) of rotation of the plane of the front and / or rear wheels and / or elements of intermediate or secondary kinematic pairs of transmission of the rotational force to the bicycle wheel supports,

however, one or more frame elements, including a tubular frame element, a rotational shaft of the plane of the front and / or rear wheels and / or a longitudinal element of the kinematic pair located therein can have a telescopic connection along the length, with the possibility of fixing on a given length.

The invention is illustrated by examples, which are illustrated by the following figures (from 1 to 10).

In this figure, the view is located so that the axis of rotation of the shaft, which transfers the turning force further to the wheel support, is perpendicular to the plane of the drawing and intersects with it at point O.

The implementation of the invention.

In all examples, the rotation node of the bicycle contains

the left and right handle of rotation of the bicycle, which are fixed on both sides to the frame of the bicycle with the possibility of rotation of each handle around its own axis, stationary relative to the frame,

as well as a mechanism for transmitting the turning force of each or both handles to the supports of the front, rear or both wheels through a kinematic connection in the form of one or more kinematic links, pairs, including in the form of a left and right sequence of links for transmitting force, mounted on a bicycle frame turning from the corresponding handle to turning the plane of the front wheel and / or turning the plane of the rear wheel of the bicycle.

At the same time, the rotation knobs themselves and the elements of the mechanism for transmitting the efforts of turning the knobs to turn the wheels, including the primary elements of the kinematic links of the transmission of turning the knobs to the wheel supports, are placed and fixed on the frame in front of the bicycle in the area of the usual arrangement of the hands of the cyclist.

Option 1 of the kinematic connection of the rotation node of the bicycle is shown in FIG. 1 (solid lines), as well as in FIG. 2. In it, the bicycle turning assembly allows the bicycle to be turned using only the front wheel.

In this embodiment, the kinematic links of transmitting the steering force from the handles of the turning unit represent a subunit - a three-link transmission of the turning force simultaneously from the left handle 1.1 and the right handle 1.2 of the turning unit by direct kinematic connection to the primary rotation shaft 4 of the front wheel plane and, accordingly, further on the support of this wheel.

Note that in the embodiments shown in FIG. 1, 2, 4, 5, 7, 8, the transmission of the rotational forces of the handles and the engagement of the kinematic pairs is carried out using bevel gears (hereinafter referred to as gears), and fixed coaxially on the corresponding handle, on the corresponding axis and / or on the corresponding shaft , although this transmission can be carried out using, among other things, cylindrical gears and / or linkage elements, pin drives and / or slotted wings mounted coaxially on the corresponding handle, on the corresponding axis and / or on the corresponding shaft, and using helical, globoid and other types of gears.

In the examples of FIG. 1 and FIG. 2 on the handles 1.1 and 1.2, the corresponding gears 2.1 and 2.2 are coaxially fixed (or firmly fixed on them), which are meshed with gear 3, also coaxially mounted on the primary shaft 4 of rotation of the front wheel plane. In this example, the rotation shaft 4 is engaged or directly attached to the support of the rotatable front wheel of the bicycle.

Also in the embodiments shown in FIG. 1, 2, 4, 5, 7, 8, 10 (diagram), it is assumed that each indicated handle of the turning unit has such a shape, size, and is positioned so that the cyclist can grab it and turn it around to transmit the turning force its axis with the fingers and / or brush of the corresponding hand, regardless of the rotation or displacement of its torso.

Moreover, in possible variants of the rotation unit, each handle is mainly made in the form of the same tube or rod having a cylindrical or close to cylindrical shape, located symmetrically on the sides relative to the vertical frame of the bicycle, with the possibility of rotation of each handle around its rotation axis, matching or parallel cylinder axis

and / or each handle can be fixed or the handle itself can be a lever or a trigger pusher, mainly of the same shape, perpendicular or inclined to the axis of rotation of the corresponding handle, while the handles are located symmetrically relative to the vertical plane of the bicycle frame, with the possibility of turning the lever or pusher together with the handle around the axis of rotation of the handle,

at the same time, to transfer the turning force, the left and right handles of the bicycle turning unit must have the constructive ability to turn in opposite directions.

Moreover, inside one or more supporting tubular elements of the bicycle frame, it is possible to place the primary (e) shaft (s) of rotation of the planes of the front and / or rear wheels and / or elements of intermediate or secondary kinematic links, pairs of transmission of the turning force to the bicycle wheel supports,

wherein one or more frame elements, including a tubular frame element, a rotational shaft of the plane of the front and / or rear wheels and / or a longitudinal element of the kinematic link located therein, can have a telescopic connection along the length, with the possibility of fixing it at a given length.

In the examples shown in FIG. 1, 2, 4, 5, 7, 8, the indicated handles 1.1 and 1.2 are made in the form of a pair of identical cylindrical rods, the axis of each cylinder coincides with the axis of rotation of the corresponding handle, in the examples these axes are on the same line perpendicular to the plane of symmetry of the rotation node ( which coincides with the plane of the bicycle frame).

In option 1 (Fig. 1, 2 - solid lines), the operation of the rotation node of the bicycle and the method are as follows.

During the movement of the bicycle, the cyclist, for example, to turn to the right, turns the left handle 1.1 of the rotation node of the bicycle around its axis of rotation (with the palm of the handle on top of itself around the circumference of the handle cylinder). In this case, the right handle 1.2, connected via gears 2.1-3-2.2 with the handle 1.1, has the ability to turn in the opposite direction, and the cyclist’s palm helps her to turn and, by turning both handles, transfer force to the shaft 4, which in this case turns the plane front wheel to the right. In FIG. 3 shows the track 5 of the contact of the front wheel of the bicycle with the ground, and the arrow indicates the rotation of its plane.

Thus, due to the corresponding rotation of the handles 1.1, 1.2, the plane of the front wheel (and its track 5) is rotated to the right, so the bicycle turns along the track to the right. When turning the corresponding handles in the opposite direction, the bicycle turns to the left.

In addition, in all versions of the method and operation of the turning unit, in order to maintain balance and stability of the bicycle, in the process of movement the cyclist shifts the center of gravity of his and / or bicycle relative to the reference points of the bicycle with the ground in the direction opposite to the direction of the pushing forces.

Option 2 of the kinematic connection of the rotation node of the bicycle is shown in the same FIG. 1 solid and dotted lines together.

It corresponds to the rotation of the bicycle by rotating the plane of the front and rear wheels at the same time, while the design of the rotation unit corresponds to option i (see the essential features and the claims).

According to this option, the kinematic links of the transmission of the rotational effort from the knobs of the rotational unit are a structural unit in the subassembly — a three-link transmission of the rotational effort from each of the indicated handles 1.1 and 1.2 to the corresponding gears 2.1 and 2.2, each attached coaxially to the corresponding handle, these gears are directly engaged with gear 3. The latter is mounted on the primary rotation shaft 4 of the plane of the front wheel and transfers, respectively, the turning force further to the front wheel support. Moreover, also from the specified shaft 4, its rotation through another kinematic pair is transmitted to the primary rotation shaft 8 of the plane of the rear wheel and, accordingly, further to the rear wheel support. This other pair is shown by a dotted line, it forms a gear 6 engaged coaxially on the shaft 4, and the gear 7 mounted coaxially on the shaft 8, which is also shown by a dotted line.

In option 2 (Fig. 1 - solid and dashed lines together) the operation of the rotation node of the bicycle and the method are as follows.

During the movement of the bicycle, the cyclist, for example, to turn to the right, turns the left 1.1 and / or right 1.2 handle of the bicycle turning unit around its axis in the same manner as in the previous version 1. The force transmitted to the shaft 4 rotates the plane of the front wheel of the bicycle to the right (see track 5 of the front wheel in FIG. 9). At the same time, gear 6 mounted on this shaft, by its engagement with gear 7, provides rotation of shaft 8, which rotates the plane of the rear wheel of the bicycle to the left (see trace 11 of the rear wheel in the same Fig. 9). The arrows indicate the rotation of the track of each wheel when turning the bicycle to the right.

Thus, due to the corresponding rotation of the handles 1.1, 1.2, the plane of the front wheel (and its track 5) is rotated to the right and the plane of the rear wheel (and its track 11) - to the left, so the bicycle turns along the track to the right. When turning the corresponding handles in the opposite direction, the bicycle turns to the left.

The kinematic connection embodiment 3 of the bicycle turning unit is shown in FIG. 4 (solid lines) and FIG. 5.

According to this option, the kinematic links of the transmission of the rotational effort from the knobs of the rotational unit are a structural unit in the subassembly — a three-link transmission of the rotational effort from each of the indicated handles 1.1 and 1.2 to the corresponding gears 2.1 and 2.2, each attached coaxially to the corresponding handle, these gears are directly engaged with gear 9. The latter is mounted on the primary shaft 10 of rotation of the plane of the rear wheel and, accordingly, transfers the turning force further to the support of the rear wheel of the bicycle Yes.

In option 3 (Fig. 4, 5 - solid lines) the operation of the rotation node of the bicycle and the method are as follows.

During the movement of the bicycle, the cyclist, for example, to turn right, turns the right 1.1 and / or left 1.2 handle of the bicycle rotation unit around its axis in the same manner as in option 1. The force transmitted from gears 2.1 and 2.2 to gear 9 and, accordingly, on the shaft 10, it turns the plane of the rear wheel of the bicycle to the left (see in Fig. 6 the track 11 of the rear wheel and the arrow indicating the rotation of its plane), while the bicycle turns to the right.

Thus, due to the corresponding rotation of the handles 1.1, 1.2, the plane of the rear wheel (and its track 11) is rotated to the left, so the bicycle turns along the track to the right. When turning the corresponding handles in the opposite direction, the bicycle turns to the left.

Option 4 of the kinematic connection of the bicycle turning assembly is shown in the same FIG. 4 solid and dotted lines together.

It corresponds to the rotation of the bicycle by turning the planes of the front and rear wheels at the same time, while the design of the turning unit corresponds to option ii (see the essential features and the claims).

According to this option, the kinematic links of the transmission of the rotational effort from the knobs of the rotational unit are a structural unit in the subassembly — a three-link transmission of the rotational effort from each of the indicated handles 1.1 and 1.2 to the corresponding gears 2.1 and 2.2, each attached coaxially to the corresponding handle, these gears are directly engaged with gear 9. The latter is mounted on the primary shaft of rotation 10 of the plane of the rear wheel and, accordingly, transfers the turning force further to the support of the rear wheel of the bicycle Yes. Moreover, also from the specified shaft 10, its rotation through another kinematic pair is transmitted to the primary rotation shaft 14 of the plane of the front wheel and, accordingly, further to the front wheel support. This other pair is shown with a dashed line; it forms a gearing 12 mounted coaxially on the shaft 10, and a gear 13 mounted coaxially on the shaft 14, which is also shown with a dashed line.

In option 4 (Fig. 4 - solid and dashed lines together), the operation of the bicycle turning unit and the method are as follows.

During the movement of the bicycle, the cyclist, for example, to turn right, turns the left 1.1 and / or right 1.2 handle of the bicycle turning unit around its axis in the same manner as in option 1. The force transmitted to the shaft 10 rotates the plane of the rear wheel of the bicycle to the left (see trace 11 of the rear wheel in FIG. 9). At the same time, the gear 12 mounted on this shaft, by its engagement with the gear 13, provides a rotation of the shaft 14, which rotates the plane of the front wheel of the bicycle to the right (see track 5 of the front wheel in the same Fig. 9). The arrows indicate the rotation of the track of each wheel when turning the bicycle to the right.

Thus, due to the corresponding rotation of the handles 1.1, 1.2, the plane of the front wheel (and its track 5) is rotated to the right and the plane of the rear wheel (and its track 11) - to the left, so the bicycle turns along the track to the right. When turning the corresponding handles in the opposite direction, the bicycle turns to the left.

Option 5 kinematic connection node rotation of the bicycle shown in FIG. 7 and 8. It corresponds to the rotation of the bicycle by turning the planes of the front and rear wheels at the same time, while the design of the turning unit corresponds to option iii (see the essential features and the claims).

According to this option, the kinematic links of transmitting the steering force from the handles of the turning unit are a constructive combination into a complex subunit: the first three-link gear transmission 2.1-3-2.2 transfers the turning force simultaneously from each handle, by direct kinematic connection to the input shaft 4 of rotation of the front wheel plane and, accordingly, further to the front wheel support, and in parallel, the second three-link gear transmission 2.1-9-2.2 transfers the turning force simultaneously from each same handle to the direct kin aticheskoy coupled to the input shaft 10 of the rear wheel rotation plane and, therefore, further to the rear wheel support.

In this option (iii) the rotation shafts 4 and 10 of the planes of the front and rear wheels are not connected by a direct connection, like a kinematic pair, but are connected indirectly, through the kinematic connection of each shaft with the handles of the bicycle turning unit.

In the example of FIG. 7, 8, the operation of the rotation node of the bicycle and the method are as follows.

During the movement of the bicycle, the cyclist, for example, to turn to the right, turns the left 1.1 and / or right 1.2 handle of the bicycle rotation unit around its axis in the same manner as in option 1. The force transmitted from the three-link gear transmission 2.1-3-2.2 to shaft 4, rotates the plane of the front wheel of the bicycle to the right (see track 5 of the front wheel in Fig. 9). At the same time, the force transmitted from the three-link gear transmission 2.1-9-2.2 to the shaft 10 turns the plane of the rear wheel of the bicycle to the left (see trace 11 of the rear wheel in the same Fig. 9). The arrows indicate the rotation of the track of each wheel when turning the bicycle to the right.

Thus, due to the corresponding rotation of the handles 1.1, 1.2, the plane of the front wheel (and its track 5) is rotated to the right and the plane of the rear wheel (and its track 11) - to the left, so the bicycle turns along the track to the right. When turning the corresponding handles in the opposite direction, the bicycle turns to the left.

In FIG. 10 shows a kinematic diagram of embodiment 6 of a bicycle turning assembly using an intermediate kinematic link (helical gear) for transmitting force from the handles to a rotation shaft of a bicycle wheel plane.

Here the handles: left - 1.3 and right - 1.4 are in the form of cylindrical tubes. The handles have the ability to rotate each around its axis, coinciding with the axis of its cylinder, while all the axes lie on one common line. The handles 1.3 and 1.4 are connected by meshing, respectively, with the right 15.1 and left 15.2 branches of the helical gear, which can translate left or right (from one handle to another). The branches 15.1 and 15.2 of the helical transmission have a mutually opposite direction of the screw, the straight line of their displacement lies on the same common line as the axis of the handles. These branches are connected by a slider 16 mounted in fixed guides, which provide its displacement along the specified common line when turning the handles within a given range. In the center of the slider 16, a rod 17 is fixed, the end of which interacts with the crank 18, while the axis of rotation of the crank (in Fig. 10 this axis intersects the plane of the figure at point O) coincides with the axis of the primary shaft of rotation of the plane of the wheel to which the steering force is transmitted handles 1.3 and 1.4 and which provides the rotation of the bike.

In the drawing, the stationary load-bearing elements of the rotation unit and the bicycle frame are shaded. The arrows indicate the direction of translational movement of the slider 16 and the limit of rotation of the crank 18.

The rotation of the handles 1.3 and 1.4 in opposite directions with the help of screw gears 15.1 and 15.2 is converted into the translational movement of the slider, the rod 17 of which converts this movement into a rotation of the rotation shaft with the O axis. This shaft rotates the plane of the steered bicycle wheel in the corresponding direction.
