External rotor motor cyrtoconic swing type self-adaption automatic variable speed drive assembly of electric motor car

Abstract

The invention discloses an external rotor motor cyrtoconic swing type self-adaption automatic variable speed drive assembly of an electric motor car. The external rotor motor cyrtoconic swing type self-adaption automatic variable speed drive assembly comprises a drive motor, a box body, a transmission shaft, a slow gear transmission mechanism and a mechanical intelligent self-adaption variable speed assembly. An annular sunk portion is formed in the axial end face of an outer ring of an overturn clutch of the slow gear transmission mechanism, an inner ring is arranged in the annular sunk portion in a rotating and matched mode, and a meshing space is formed between an outer circle of the inner ring and the inner wall of the radial outer side of the annular sunk portion. The slow-gear transmission mechanism outputs power and locks a variable speed elastic element through a swing type end face cam meshing pair. By means of the automatic variable speed drive assembly, the problem that the transmission error is amplified on the overturn clutch is avoided, the overall stability of the overturn clutch is guaranteed, stable supporting is still guaranteed after long period operation of a speed changer, operation noise is lowered, operation comfort is guaranteed, transmission efficiency is improved, and thus energy consumption is lowered; the service life is further prolonged, operation accuracy is improved, and the automatic variable speed drive assembly is applicable to overloading and high-speed use environments.

Description

technical field [0001] The invention relates to a motor vehicle transmission, in particular to an electric motorcycle outer rotor motor bow cone pendulum 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 the accelerator pedal depends entirely on the operation of the driver, which often results in a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor and stalling. [0003] In motor vehicles, when the rider does not know the driving resistance, the speed change device is only operated and controlled based on experience, which inevitably has the following problems: 1. When starting, going uphill...
