Belt transmission structure of two wheel electric motorcycle

Abstract

The invention discloses a belt transmission structure of a two wheel electric motorcycle. The structure comprises a driving wheel driven by the output shaft of a motor, a driven wheel sleeving the input shaft of a back wheel and a transmission belt on the driven wheel, wherein the transmission belt is a gear belt and the driving and driven wheels are gear-shaped wheels; the input shaft comprises ashaft body and an engaging portion located at one end of the shaft body; the driven wheel comprises a gear ring assembled on the transmission belt and a fixed plate on the outer side thereof; the gear ring is provided with a center hole greater than the shaft body, so that the gear ring in the assembling process can sleeve the shaft body eccentrically; an assembly hole coaxial with the gear ringis formed in the fixed plate, and the assembly hole and the engaging portion are in engaged connection to synchronously rotate the driven wheel and the input shaft. The transmission belt and the driving and driven wheels are engaged in a gear shape for realizing transmission, so that the transfer efficiency is higher and the torque can be transferred better. The driven wheel is split into the gearring and the fixed plate, so that the transmission belt is assembled conveniently, and the belt transmission structure is simple and reasonable in structure, and the assembling efficiency is improved.

Description

Technical field [0001] The invention relates to an electric motorcycle, in particular to a belt transmission structure of a two-wheel electric motorcycle. Background technique [0002] The power mechanism of an electric motorcycle includes a drive motor, a driving wheel, a driven wheel, a V-shaped transmission belt and a reduction gear box. Among them, the driving wheel is arranged on the output shaft of the driving motor, the driven wheel is connected with the power input shaft of the reduction gear box, the driving wheel and the driven wheel are connected by a V-shaped transmission belt, and the rear wheel of the electric motorcycle is arranged on the reduction gear box On the output shaft. [0003] Since the drive motor and the reduction gearbox are fixedly installed on the frame, the center distance between the output shaft of the drive motor and the power input shaft of the reduction gearbox is fixed. When assembling, it is necessary to cover the driving wheel and the driven...

AI Technical Summary

Problems solved by technology

[0004] For the existing V-shaped transmission belt, the linkage is realized through the friction between the two side walls and the driving and driven wheels, the transmission efficiency is low, and slipping is prone to occur.

[0005] In addition, since the center distance between the driving and driven wheels is not variable, the conveyor belt needs to be stretched by a large external force before it can be assembled in place, which is time-consuming and laborious; and this process may cause irreparable damage to the conveyor belt with poor elasticity. damage, resulting in reduced transmission efficiency and even potential safety hazards
