AI Technical Summary

Technical Problem

Existing motorcycle reversing devices are not compatible with different motorcycle models, and when riding on bumpy roads, they can easily cause the chain to move in a restricted manner or malfunction, posing a safety hazard.

Method used

A motorcycle reversing assist device was designed, which includes a gear assembly and a safety device inside the housing. The sliding engagement of the intermediate gear is controlled by an electromagnet to ensure that the chain movement is not blocked when the motor is not working, and the sprocket height can be adjusted to adapt to different motorcycle models.

Benefits of technology

This technology enables the smooth transmission of chain movement when the motorcycle is reversing, avoiding gear meshing problems caused by vibration and improving the applicability and safety of the device.

Abstract

The invention provides a motorcycle reversing auxiliary device which comprises a box body and a gear assembly arranged in the box body, the gear assembly comprises two oppositely and fixedly arranged inner plate bodies, an input gear rotationally arranged between the two inner plate bodies, an intermediate gear and an output gear, the output gear is coaxially and fixedly connected with an output shaft, the output shaft is coaxially and fixedly connected with a chain wheel, and the chain wheel is coaxially and fixedly connected with a transmission shaft. First sliding grooves are formed in the two inner plate bodies, the middle gear can slide along the first sliding grooves, the middle gear is meshed with the input gear all the time, and when the motor works, the input gear drives the middle gear to slide and enables the middle gear to be meshed with the output gear. A safety piece used for preventing the intermediate gear from sliding towards the output gear when the motor is in a non-working state is arranged between the two inner plate bodies, the safety piece can be separated from blocking the intermediate gear when the motor works, the intermediate gear can be prevented from sliding towards the output gear when the motor is in the non-working state, and the situation that the action of a chain is limited by the motor is avoided; and the intermediate gear is not meshed with the output gear due to vibration.
