Waved friction-driven side-hung self-adaptive automatic variable-speed driving assembly for electric motorcycle

Abstract

The invention discloses a waved friction-driven side-hung self-adaptive automatic variable-speed driving assembly for an electric motorcycle. The waved friction-driven side-hung self-adaptive automatic variable-speed driving assembly comprises a box body, a transmission shaft, a slow-gear transmission mechanism and a mechanical intelligent self-adaptive variable-speed assembly; the box body is provided with a mounting part used for being mounted on the hub side in a side-hung manner; and the friction surface of a driving friction disc and the friction surface of a driven friction disc of the mechanical intelligent self-adaptive variable-speed assembly adopt waved friction surfaces to form a friction drive pair. According to the waved friction-driven side-hung self-adaptive automatic variable-speed driving assembly, the friction discs are adopted to form a separable and combinable structure to achieve the advantage of sensitive response, and the axial size is relatively small; meanwhile, as the structure that a ring-shaped bulge and a ring-shaped groove of the friction surfaces with the waved radial sections are mutually in embedded connection with each other is adopted, engagement of the friction surfaces is dispersed, the coaxiality of the driving friction disc and the driven friction disc is favorably guaranteed, the friction surfaces are favorably increased, and favorable transmission is ensured under the condition of limited elastic force; and the separation and combination sensitiveness is favorably guaranteed, the transmission precision is improved, and the waved friction-driven side-hung self-adaptive automatic variable-speed driving assembly is suitable for the field of electric motorcycles.

Description

technical field [0001] The invention relates to a motor vehicle transmission, in particular to a wave-shaped friction transmission side-mounted 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 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....

Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a wave-shaped friction transmission side-mounted self-adaptive automatic transmission drive assembly of an electric motorcycle, which can not only automatically perform gear shifting without cutting off the driving force due to changes in driving resistance , to 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, ensure operating comfort and improve transmission efficiency, thereby reducing energy consumption; change the fast and slow gear engagement and separation mechanism The status quo of the long stroke of the axial joint surface, the separation and joint are fast and thorough, which is conducive to improving the transmission accuracy, and the overall shape and position tolerance will still be guaranteed after long-term use, so as to ensure the stability of the transmission
