Description

ELECTRIC DRIVE FOR ROLLER BOARD AND ELECTROLONG

BORD Field of Technology

The present invention relates to the construction of roller boards, in particular, to the design of a longboard, namely, electro-arcboard.

Prior art

Longboard is a kind of roller board, characterized by increased stability and improved handling qualities. The main element of the longboard is the deck, on which the wheelbase, wheels and skin are fastened (gripe, sandpaper - non-slip coating). A special feature of the deck is its elasticity, the ability to change its geometry under static or dynamic stress during rolling. Pendants (tracks) are designed to provide a smooth ride and convenient control of the longboard. They consist of a baseplate (metal plate at the base), a henger (hanger) in which an axis is embedded, on which the wheels are attached and a kingpin (a bolt connecting the base and the “hanger”). Between the deck and the suspension are mounted risers that serve to lift the deck and thereby change the driving characteristics of the longboard, as well as the bushings, which are vibration dampers. Inside the wheels are installed two bearings, between which often put the sleeves-spacers. (https: //ru.wikipe-dia.org/wiki/Longboard).

Longboards are different from other roller boards, in particular from the classic skateboard, with an extended wheelbase and deck, and also have softer and larger wheels (https://ru.wikipedia.org/wiki). This design allows you to develop high speeds, to feel on the board is more stable, while moving gently, almost without noticing minor defects of the road surface.

An extension of a longboard is a electric board, which is similar in design to a conventional longboard — deck, suspension, wheels, bearings, bushings, but additionally equipped with an electric motor with a corresponding electric drive to the wheel axle with a connector and a remote control (https: // www. megaskate.ru/poleznoe/sta-ti / vse-ob-elektrolongbor-dax; US8550480). The engine, as a rule, is controlled by a remote control panel, therefore the necessity of repulsion from the ground is eliminated, putting the design into action. The remote has a lever or buttons "back and forth". In this case, turns and adjustment of the trajectory of movement is carried out due to the deck tilt.

The engine is attached to the tracks, for example, using steel angle bars and screws with self-locking nuts, and the rotation is transmitted by means of a drive consisting of toothed pulleys, one of which is mounted on the wheel axle and a belt with teeth (pikabu.ru/tour/ yelek-trolong-bord _svoimi_rukami_chast_l_3549575; pikabu.ru/story/ye-lektrolong-bord_svoimi_ rukam i_chast_2_3555119). The disadvantage of such a construction of the electric board is the difficulty of mounting and dismounting the drive in the event of an engine malfunction, as well as the possibility of dust and dirt particles entering the drive during the movement of the longboard.

The closest to the claimed group of inventions is an electric drive to a longboard, consisting of a motor with a rotating rod, on which a roller is attached, pressed against the rim of the wheel and connected to it the connecting element, and the electric board, in which it is used as a structural element (https: // www. kickstarter. com / pro-jects / 424686603 / kickr-electrify-eveiy-longboard? refNiav_search; fy-every-long- board).

The disadvantage of the design is the loss of engine power to overcome internal resistance due to direct pressure of the roller and wheel to each other, the need for additional adjustment of the pressing force when the axle weight changes, and the possibility of dirt or water entering the coupling point engine with a wheel because of what may erase clutch contact due to the action of friction forces.

The problem solved by the author was to create a more reliable and simple to operate electric drive, in particular, allowing for quick assembly and disassembly of an engine suitable for installation on roller boards of any type, as well as an electric board based on it.

Summary of Invention

The technical result in relation to the electric drive is that the inventive electric drive containing a regulating unit connected by transmission to the engine block, a protective casing and mounting the electric drive to the wheel axle, has the electric drive mounting to the wheel axle realized through the outer surface of the wheel a disk equipped with pointed protrusions located above the surface of the disk and mounted on an axis with the possibility of controlled movement along it with the help of a regulating unit. In this case, the regulating unit consists of successive axes of the wheel of the regulating cylinder, an electric drive pulley with a bearing and a rod with a disk for fixing the casing connected to the fixing disk. The regulating cylinder is a cylinder provided with a hole under the rod in the center of one end, connected by holes with a side surface and a figured cutout for the diameter of the axis of the wheel in the opposite part.

The locking disk has a central hole with a diameter greater than the diameter of the cylinder and mounting holes.

Industrial Applicability

The electric drive unit consists of a fixing disk 6, a regulating cylinder 15; the pulley of the electric drive 8 with the bearing 9, the stem 10, the casing 11, the disk 13. The locking disk 6 serves to create contact between the electric drive and the wheel. It is a circle with a diameter of less than external diameter of the wheel and gabled protrusions 16 located above the surface of the circle. In the center of the circle there is a hole 17 with a diameter larger than the external diameter of the cylinder 15 and blind holes with a thread 18 and no thread 19. (FIG. 3 c), d), e)). The disk is bolted to the pulley 8 in such a way that the mounting allows, by moving along the cylinder axis, first press the disk with pointed protrusions to the wheel, and then fix this pressing.

The control cylinder 15 serves to fix the electric drive unit on the axis of the electrolongboard wheel 4. The cylinder is provided with a non-through hole for the rod 21 in the center of one end, connected by holes 20 to the lateral surface and figured notch 22 for its installation on the wheel axis parts.

The pulley of the electric drive 8 with the bearing 9 and the disk 6 serves to transfer the rotational movement from the engine to the wheel of the longboard 3, as a rule, by means of a toothed belt. Instead of a belt other known devices can be used, for example, a flexible cable. The bearing, pulley and disc is mounted on the rod 10 with the disk 13. The rod 10 is attached to the regulating cylinder 15. This mounting allows you to adjust the movement and fixation of the electric drive in relation to the wheel 3 along the axis of the cylinder

15. The disk 13 mounted on the rod 10 is intended for fastening the casing 11. The end part of the disk is provided with a groove 28 and is provided with holes 31 for bolting the casing 11 and a key hollow 29 by means of which the electric drive is fixed on the wheel axis. The casing 11 is made in the form of a flat duct 33, the upper part of which is closed on the inner side and provided with a notch 34 wider than the diameter of the motor shaft, and the lower part is equipped with a rounded notch 35 with a diameter corresponding to the diameter of the groove 28 of the disk 13. The notch 35 allows pitch the disk 13 of the rod 10 when fixing the electric drive on the wheel axle and choose the optimum angle of attachment so that the engine attached to the casing is protected from contact with the surface along which the electric board will move. The depth of the casing is chosen in such a way as to ensure the free rotation of the pulley of the engine 12. The casing is fixed by a cutout 35 and bolts through the holes 36, and the engine 5 is fixed by bolts through the holes 37 in the casing.

The drive can be installed both on the longboard and on other types of wheel boards, provided that the locking disk is smaller than the wheel diameter. When mounted on a longboard, the drive is fixed on the axis 4 of one of the wheels 3.

The drive unit is mounted on a longboard as follows. The nut is removed from the wheel axle. Adjustable stem 10 in the control cylinder 15, depending on the size of the wheel 3 and is fixed. The control cylinder 15 by means of a notch turnkey 29 on the disk 13 of the rod 10 is mounted on the axle of the wheel 4. The angle of attachment of the casing 11 is selected, so that the engine mounted on the casing does not touch the surface over which it will move electrolongboard and bolted through the holes 31 of the disk 13. Bolts, through the holes 26 in the pulley 8 and through the holes 32 of the disk 13, the locking disk 6 is pressed against the surface of the wheel 3 and fixed so that the projections 16 abut the tire wheel 3.

The drive unit is assembled as follows. The bearing 9 is placed in the slot 23 of the pulley 8 and is put on the rod 10 until it stops. The bolts 8 are screwed into the holes 26 of the pulley 8 so that they do not look on the side of the bearing 9. The two bolts are screwed into the holes 18 of the disk 6 and inserted into the counter holes 27 of the pulley 8. Control cylinder 15 through the hole 20 with a bolt fastens on the rod 10 into the hole 21, the second bolt is screwed into the hole 30 of the rod 10. The disk 13 of the rod 10 into the groove 28 is fitted with a cover 11 with a notch 35. A belt is driven into the pulley 8, the other end of which is engaged by the pulley 12 of the motor 5 when threading the motor shaft through the cut-out 34 of the casing 11, then the motor is fixed with bolts through the holes 37 of the casing 11. The casing 11 through the holes 36 is fixed with a bolt on the disk 13.

Installing the electric drive on the roller board and, if necessary, disassembling it takes 1-2 minutes, and when using it, the longboard has 10% more power than the closest analogue by eliminating internal resistance due to direct pressing of the roller and wheel to a friend, and also has maximum engine protection against contamination. Immersing the protrusion blades into the wheel to a depth of more than 1 mm provides the ability to pull a weight of about 100 kg without losing the quality of adhesion over time, since nothing is erased and is resistant to dirt / moisture.
