Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described:
One, self-controlled type constant speed free wheel device
Compare with the free wheel device of existing function singleness, it is characterized in that: the roller between Internal and external cycle overlaps positioning control by roller, the roller cover only is connected with individual pen, and under this circle is controlled according to the robot control system(RCS) of self rotating speed response, can be by relative by a small margin the swing offset of control roller cover with this circle, control roller and whether enter separation or engage rail position between Internal and external cycle, thereby realize automatically controlling and constant speed joint or separate purpose.
Referring to Fig. 1, Fig. 2, Fig. 3.Suppose that clutch is to clockwise rotate, inner ring is driving wheel, and the roller cover is connected automatic control with the outer ring, also rotates or rotating speed when not high when the outer ring, and shown in Fig. 1-1 and Fig. 1-3, the roller of clutch all is in the separated state of initial position.After the outer ring reached certain rotating speed and starts self controller and drive roller cover swing offset α angle, roller was driven by the roller cover and squeezes into the Internal and external cycle engagement positio, and at this moment, if inner ring rotating speed during greater than the outer ring, Fig. 1-2 is depicted as jointing state; When the outer ring rotating speed during greater than inner ring, just be in and surmount separated state.
On clutch outer, two bolt fixed holes 9 are only folded fixation to the axial thrust of both sides, outer ring.Another two is bolt and sleeve column disjunctor 14,17 common fixed hole.This a pair of sleeve column 14, the 17 sleeve column holes 16 by roller cover plate 26 extend to sleeve column 17 positions, and are connected with the control sleeve column contraction spring 19 of robot control system(RCS) by the sleeve column orbit hole 24 on connecting rod 20.And with the composition combined control system of connecting rod centrifugal force controlled spring 21.
When specific design, the angle of displacement α that the roller swing offset angle α 2 on the outer ring should be slightly less than on the roller cover plate.Owing to also leaving a little gap between roller and roller cover, facilitate roller to rotate in the roller cover, so appended a pair of sleeve column fine setting ring compression 23 on the connecting rod of robot control system(RCS).Referring to Fig. 1, Fig. 2, Fig. 8 and 28, the ab of the sleeve column orbit hole 24 on connecting rod, cd line segment are the isocentric circular arc line segments, and ad, bc are the semi-circlees that is slightly larger than sleeve column 28 circumference.Like this, synchronous rotation along with outer ring and sleeve column dish, under the centrifugal action that the parts such as connecting rod produce, sleeve column 28 just can and be controlled under the jointly controlling of coil tension spring 19 and 21 at centrifugal force linkage component 20, carries out suitable displacement in the confined space in connecting rod orbit hole 24 and cover plate sleeve column hole 16.Reach default rotating speed lower limit along with clutch rotational speed further improves, referring to Fig. 2-5, sleeve column 28 just by 27 position movements to 28 positions.By such finite displacement, thereby in the mode of reaction force, promote to control cover and form swing offset angle α with respect to the outer ring.Control cover just promote roller squeeze into into the free wheel device Internal and external cycle in conjunction with track curved surface position, realize the Internal and external cycle combination.Referring to Figure 10-1, along with the high one-level gear self-controlled type constant speed free wheel device joint of series connection, former gear rotating speed significantly promotes goes forward side by side into surmounting state, and sleeve column 28 just is moved further 29 positions that are positioned at Fig. 2-5.For roller, equal to retreat a little the friction of avoiding unnecessary.For the high-regime clutch of gearbox, the engagement positio of sleeve column is also the end position of orbit hole 24, sees 30 of Fig. 2-5.
This self-controlled type constant speed free wheel device in the practical application of configuration vehicle gear box, is to be connected by the clutch coaxial of several setting echelon constant speed to consist of.6 shift automatic variable speed casees referring to Figure 10, Figure 11, Figure 12.If the power that provides take the rated speed of vehicle motor is as foundation, the joint initial velocity that 4 grades, 5 grades, 6 grades clutches are set be respectively 60 kilometers/time, 90 kilometers/time, 120 kilometers/time.So at vehicle since 4 grades of processes of giving it the gun, as long as Vehicle Speed reach 90 kilometers/time, 5 grades of clutches just enter jointing state automatically under the effect of robot control system(RCS) own, and in this moment, 4 grades of clutches just automatically enter and surmount disengaged position.In like manner, when travelling speed reach 120 kilometers/time, 6 grades of clutches engage automatically, 5 grades surmount disengaging.So, can Complete Synchronization during acceleration the moment gearshift, have advantages of a bit imperceptible pause and transition in rhythm or melody sense.The final velocity of each gear is only determined by the initial velocity of high a grade.And, no matter in any moment of which gear, needing only the rotating speed of outer ring greater than the rotating speed of inner ring, this clutch surmounts separation with regard to moment, and vehicle just enters the neutral position sliding state automatically.As long as the driver takes full advantage of the highway section that can slide, in time turn off engine or make motor enter idle state, just can significantly reduce energy consumption.This type automatic transmission case that Here it is is than manual gear gearbox fuel-efficient key reason also.
According to These characteristics, as long as preset the initial velocity of each gear, rotary speed parameter, connecting rod 20 and the spring 19 of this gear clutch outer ring have also just been determined ... Deng the quality that produces the centrifugal force component, control link contraction spring 21 is in the length that specifically is stretched that rigidly connects when closing.Just can utilize the contractile force mode of balancing each other of the centrifugal force of Fig. 8 and spring to establish an equation finds the solution.Because the size and Orientation of the centrifugal force of quality, the radius of gyration and the generation of each fraction of centrifugal force parts is all different, thus can only concrete could be with test determination or solution of integral equation after determining the relevant parameter of component.This is all indispensable technical ability and mechanical knowledges of ready-made every technician, does not belong to the innovation category, the addressee absent proof of deriving.
Two, the limiter of self-controlled type constant speed free wheel device
Vehicle tends to run into long descending highway section in the process of moving, need to carry out braking deceleration to vehicle with the load of unloaded motor.So this class automatic transmission case is appended at 4 grades and has been designed 91,5 grades, 6 grades of locking shelves friction dental inlay combined clutch and appended limiter, referring to Fig. 3, Figure 10, Figure 11, Figure 12.3 gear clutch limiters are carried out synchronous interaction.The condition that this limiter can utilize the Internal and external cycle differential to rotate, rely on the synchronous and asynchronous axle of simultaneous adaptation, overlap unique design, make sleeve pipe rotate vertically propelling, so that in needs, no matter each gear self-controlled type constant speed free wheel device can entangle smoothly centrifugal force component connecting rod 20, and be pressed to initial unmated position engaging or separated state, thereby the joint of restriction self-controlled type constant speed free wheel device avoids arbor distortion or roller to be extruded cracked accident.
Three, self-controlled type friction dental inlay combined clutch
compare with friction or the jaw clutch of existing simple function, it is characterized in that: before dental inlay engages, first carrying out transition by friction clutcch engages, realize again the dental inlay smooth engagement after near synchronous speed, impact force and pause and transition in rhythm or melody sense so just can not occur, friction clutcch is to adopt axial advance, brake pad is engaged by the tangential mode of clamp-oning in sleeve pipe of sliding of circumference, take full advantage of self spring force of brake pad, restraining force in centrifugal force and sleeve pipe, realize quick smoothly engaging or separating, compare with existing friction clutcch, the external world provides the extruding force of vertical frictional direction greatly to reduce, axially advance and retreat manipulation or automatic control are just easier.
As for the specific design of friction dental inlay combined clutch, referring to Fig. 9.The width of dental inlay double wedge 40 is about half of recessed tooth 41, and the flank of tooth is convenient to engagement according to the certain oblique angle of differential sense of rotation design.Tooth root section is designed to the right angle, and β=90 ° are to reduce axial compression power.Brake pad 46 protrusion degree, brake pad Compress Spring 47 and ring limiting groove 44, and the magnitude relationship between friction sleeve inwall 42 sees Fig. 9-2 for details.During actual design was used, certain thickness wear allowance also should be left in the brake pad end, to extend the working life of brake pad.
Four, instant response self controller
Referring to Fig. 5, compare with existing mechanical centrifugal power self controller, it is characterized in that: a pair of centrifugal force component 55 are upside-down mountings, unite with the contractile force of spring and consist of a synchronous self-controlled critical speed of rotation responding system, when surpassing this critical speed of rotation, centrifugal force that these centrifugal force component produce can increase moment, and self controller thrust disc 54 will instant response and reached maximum axial displacement, thereby realizes rapid clutch function.Wherein thrust disc or reaction thrust dish have one to be fixed on synchronizing shaft.In like manner, the response speed setting of instant response self controller calculates and can carry out with reference to the self controller thinking of self-controlled type constant speed free wheel device with concrete analysis.
Five, the simplification of component merges the performance multi-function action
Referring to Fig. 3, Fig. 6.Two kinds of above-mentioned multifunctional clutch are simplified with the component such as gear mechanism axle bearing as far as possible and are merged the performance multi-function action.Forging Technology processing technique level manufacturing according to the existing machinery component, the component that as far as possible can merge merge forging and are processed into a multifunctional part, material and process of surface treatment difference as for each component, can consider to adopt the larger material of general character and treatment process and new material new process compatible, overcome existing gearbox designs complicated, the component sum is many, and manufacture cost is high, there was a mechanical failure, and probability is large, the problems of maintenance service difficulty.
As the Internal and external cycle axial thrust ring of self-controlled type constant speed free wheel device and the diameter shrinkage part at roller and two ends, just consist of thrust bearing.If we deliberately dwindle the diameter shrinkage part at roller two ends more a little, control at roller under the driving of cover rotating speed, because of the effect of centrifugal force, roller just breaks away from inner ring thrust ring surface becomes bearing without the friction Non-energy-consumption.
Thrust annulus, the outer ring of gear inside and outside wall and free wheel device outer ring, dental inlay dish, friction inner sleeve with friction dental inlay combined clutch can merge forging.The thrust button of instant response self controller, with the friction jaw clutch thrust disc can merge forging equally.
Six, 6 shift automatic variable speed casees
Give full play to the advantage of novel clutch, self controller when us, after the clutch of existing automobile gearbox, self controller, newly-designed 3 kind of 6 shift automatic variable speed case is referring to Figure 10, Figure 11, Figure 12 take them as main replacement.
Figure 10 is the 6 shift automatic variable speed casees that all are made of the novel clutch self controller of ordinary gear and this invention.It has 3 gears, main file 94,1 to 4 grades of positions locking shelves gear 87 and 1 grade of locking shelves gear 95.Gearshift between 3 gears is not independently, but go forward one by one continuously.The gear distribution diagram is seen Figure 10-4.Main file position 94---101 is neutral in the neutral position, and front 100 positions that are pushed into are reverse gears.Retreating to 99 positions is full-automatic shelves of 1 to 6 grade.The locking shelves gear 87 that goes forward one by one continuously and could cut 1 to 4 grade by this position---104, front 102 positions that are pushed into are locking shelves of 1 to 4 grade.Incision 1 grade of locking shelves 95 more continuously go forward one by one---and 103, retreating to 105 positions is exactly 1 grade of locking shelves.1
Figure 11 is the 6 shift automatic variable speed casees that are made of ordinary gear and planetary pinion simple combination.Main file position 94---106, merge 1 grade of locking shelves gear 95 with 1 to 4 grade of locking shelves gear 87---103.During for fear of reverse gear, the self-controlled type free wheel device of 4 grades independently engages, and it is the twice of reverse speed that this of setting grade clutch engages initial velocity.If the reverse gear top speed be 5 kilometers/time, 4 grades of initial velocity be made as 10 kilometers/time.When engine start, main file position 106 is at middle neutral gear position.Retreating to 100 positions is reverse gear.Before to be pushed into 102 positions be the locking shelves of 1 to 4 grade, be also the vehicle start shelves.When the speed of a motor vehicle is stable surpass 10 kilometers of the setting initial velocity of 4 grades of clutches/time after, the driver can keep this gear as required, also can return the full-automatic shelves that 106 positions become 1 to 6 grade.Follow-up speed changer gear operation mode and flow process same Figure 10-4.
Figure 12 is that ordinary gear and planetary pinion consist of the 6 shift automatic variable speed casees that comprise reverse gear.Also 3 gears, main file position 94---101, when it is upspring by spring 113 in the neutral position, be stopping brake locking shelves, be also the locking shelves of motor.When only depressing this gear, become neutral, motor could start.Before to be pushed into 100 positions are reverse gears, retreating to 99 positions is full-automatic shelves of 1 to 6 grade.Follow-up speed changer gear operation mode is same Figure 10-4 also.
Can find out from the novel 6 shift automatic variable speed case sketches of Figure 10, Figure 11, Figure 12, their main-gear box is identical, only some difference of auxiliary transmission.Main-gear box is 4 grades, 5 grades, 6 grades.Design initial velocity be 0-60 kilometer/time (Figure 11 is 10-60 kilometer/time), 90 kilometers/time, 120 kilometers/time.3 gears of main-gear box are all that self-controlled type increases progressively the constant speed free wheel device and is composed in series, 4 grades of low-medium speed locking shelves that the special-purpose 1-4 shelves of bad road surface or downhill retardation Brake Design are arranged.The auxiliary transmission velocity ratio is 1: 3.So 1 grade, 2 grades, 3 grades design initial velocity be 0-20 kilometer/time, 30 kilometers/time, 40 kilometers/time.1 grade of locking shelves that the lower abrupt slope special use of design is also arranged.With existing 6 shift automatic variable speed casees relatively, retreat shelves, neutral is similar with forward gear.In the present invention, it is called the main file position, sees 101,106.Difference is that locking 1-4 shelves are to be linked by different gears respectively with 1 grade of locking, see 104,103.Their common advantage is all apparent.
1. just find out from structural drawing, this three kind of 6 shift automatic variable speed case is more than the also simple compactness of 4 grades of manual gears.At least save a foot accelerator clutch.
2. energy loss-rate manual gear is also low.The front is mentioned, and no matter self-controlled type constant speed free wheel device needs only the rotating speed of outer ring greater than the rotating speed of inner ring in any moment of which gear, and this clutch surmounts separation with regard to moment, and vehicle just enters the neutral position sliding state automatically.As long as the driver takes full advantage of the highway section that can slide, in time turn off engine or make motor enter idle state, just can significantly reduce energy consumption.This type automatic transmission case that Here it is is than manual gear gearbox fuel-efficient key reason also.
3. gearbox has automatically the more function of shelves acceleration.When vehicle needed anxious the acceleration, not only auxiliary transmission instant response self controller started, and each of main-gear box grade self-controlled type free wheel device also starts.And high one-level gear engages and surmounts with former gear that to separate be all to synchronize moment to complete under same rotating speed state when advancing grade.Only the travelling speed to vehicle is relevant with motor output total output to accelerate shelves.Start maximum power character and the Economy of function performance.
