Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a self-adaptive automatic variable speed drive assembly of a spiral wave friction transmission for electric motorcycles, which can not only automatically perform gear shifting without cutting off the driving force as the driving resistance changes, Solve the problem that small torque-rotational speed changes cannot meet the problem of road use under complex conditions; at the same time, the overrunning clutch itself, as a necessary transmission component, can transmit smoothly, reducing the matching cam transmission structure, thereby reducing the size of the transmission

Abstract

The invention discloses a self-adaptive automatic speed change drive assembly adopting spiral wavy friction transmission for an electric motorcycle. The self-adaptive automatic speed change drive assembly comprises a box body, a transmission shaft, a slow-gear transmission mechanism and an intelligent mechanical self-adaptive speed change assembly adopting wavy friction transmission. According to the slow-gear transmission mechanism, the inner ring of an overrun clutch is sleeved with a transmission shaft sleeve and the inner circle of the inner ring is provided with a spiral cam matched with the transmission shaft sleeve. An output structure of the spiral cam is adopted in the inner ring of the overrun clutch and arranged on the transmission shaft sleeve, so that an end face cam is omitted, and the spiral cam is good in smoothness and can sensitively make a response to resistance; and multi-cam transmission is possible for the overrun clutch, wavy friction transmission is adopted for guaranteeing flexibility and stability of disengagement and engagement of friction transmission, the axial size of a speed changer is reduced, the drive assembly is suitable for hubs and the like, and good smoothness and high transmission accuracy are acquired in the speed change process.

Description

technical field [0001] The invention relates to a motor vehicle transmission, in particular to an electric motorcycle spiral wave friction transmission self-adaptive automatic variable speed drive assembly. 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 by the rider without knowing the driving resistance, the speed change device is operated and controlled only based on experience, which inevitably has the following problems: 1. When starting, ...
