Mechanical intelligent adaptive two-gear multi-cam automatic speed change driver

Abstract

The invention discloses a mechanical intelligent adaptive two-gear multi-cam automatic speed change driver which comprises a power device, a box body, a transmission shaft, a differential mechanism, a slow gear transmission mechanism, a circular ring body axial outer conical sleeve and a circular ring body axial inner conical sleeve, wherein the circular ring body axial outer conical sleeve is sleeved outside the transmission shaft and is transmitted by a helical cam pair; and the slow gear transmission mechanism adopts a multi-end-face-cam transmission structure. The mechanical intelligent adaptive two-gear multi-cam automatic speed change driver has all the advantages of the existing cam adaptive automatic speed change device, directly outputs power through the differential mechanism and is applicable to rear-mounted driving; by adopting the multi-end-face-cam slow gear transmission structure, the sensitivity during gear shifting can be guaranteed, sudden jerk and clamping stagnation which are caused by gear shifting can be eliminated, and the driving and riding comfortableness is improved; and furthermore, energy is saved, consumption is reduced, and the dynamic property, the economical property, the driving safety and the comfortableness of vehicles are greatly improved.

Description

technical field [0001] The invention relates to a motorized drive structure, in particular to a mechanically intelligent self-adaptive two-speed multi-cam automatic variable speed drive. 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, going uphill and wit...
