Side-hung bow cone swing type self-adaption automatic variable-speed drive assembly for electric motorcycle

Abstract

The invention discloses a side-hung bow cone swing type self-adaption automatic variable-speed drive assembly for an electric motorcycle. The side-hung bow cone swing type self-adaption automatic variable-speed drive assembly comprises a box body, a transmission shaft, a slow-gear transmission mechanism and a mechanical and intelligent self-adaption variable-speed assembly. An annular concave part is formed in the axial end face of the outer ring of an overrun clutch of the slow-gear transmission mechanism. The inner ring of the overrun clutch of the slow-gear transmission mechanism is arranged in the annular concave part. A meshing space is formed between the outer circle of the inner ring and the inner wall of the radial outer side of the annular concave part. The slow-gear transmission mechanism outputs power and locks a variable-speed elastic part through a swing type end face cam meshing pair. By means of the side-hung bow cone swing type self-adaption automatic variable-speed drive assembly, a traditional structure that the inner ring is directly supported by the transmission shaft is avoided, the problem that the transmission error is amplified on the overrun clutch is solved as well, the overall stability of the overrun clutch is ensured, stable supporting can still be ensured after a transmission runs for a long period, the running noise is reduced, the running comfort is ensured, the transmission efficiency is improved, and therefore the energy consumption is lowered; the service life is prolonged, the running accuracy is improved, and the side-hung bow cone swing type self-adaption automatic variable-speed drive assembly is suitable for heavy-load and high-speed use environments.

Description

technical field [0001] The invention relates to a motor vehicle transmission, in particular to a side-mounted bow-cone-pendulum self-adaptive automatic transmission drive assembly of an electric motorcycle. Background technique [0002] In the prior art, automobiles, motorcycles, and electric bicycles basically directly control the throttle or current control speed through a speed control handle or an accelerator pedal, or use a manual mechanical automatic transmission mechanism to realize speed change. The operation of the handle or accelerator pedal depends entirely on the driver's operation, which often causes a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor or engine, and stalling. [0003] When the motor vehicle is operated and controlled by the rider only based on experience without knowing the driving resistance, the following problems inevitably exist: 1. When starting, going uphill and with a large load, the m...

Problems solved by technology

[0006] In view of this, the object of the present invention is to provide a side-mounted bow-cone pendulum adaptive automatic transmission drive assembly of an electric motorcycle, which can not only automatically perform gear shifting without cutting off the driving force when the driving resistance changes, Solve the problem that small torque-rotational speed changes cannot meet the problem of road use under complex conditions; long-term operation can still ensure stable support, reduce operating noise, and have better stability and smoothness when the slow gear transmission returns to release the variable speed elastic member, Eliminate frustration and noise, help to further improve work efficiency, have better energy saving and consumption reduction effects, and increase service life
