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

Abstract

The invention discloses an inner rotor motor swing type self-adaption automatic variable speed drive assembly of an electric motor car. The inner rotor motor swing type self-adaption automatic variable speed drive assembly comprises an inner rotor drive motor, a slow gear transmission mechanism and a mechanical intelligent self-adaption variable speed assembly. The slow gear transmission mechanism comprises an overrun clutch and a middle speed reduction transmission mechanism. The overrun clutch transfers and outputs slow gear power through a slow gear cam meshing pair. The slow gear cam meshing pair comprises a swing type end face cam meshing pair at a minimum. The inner rotor motor swing type self-adaption automatic variable speed drive assembly has all the advantages of an existing cam self-adaption automatic variable speed device, swing cushion is achieved in the gear shifting process, good steadiness and smoothness are achieved when a variable speed elastic piece is released, sense of frustration and noise are eliminated, and further improvement of working efficiency is facilitated; transmission energy consumption generated in the gear shifting process is lowered, better energy conservation and consumption reduction effects are achieved, the service life is prolonged, and the inner rotor motor swing type self-adaption automatic variable speed drive assembly is more applicable to electric motor cars and other light and portable vehicles.

Description

technical field [0001] The invention relates to a motor vehicle transmission, in particular to a pendulum type self-adaptive automatic variable speed drive assembly of an inner rotor motor 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 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...

Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide an electric motorcycle inner rotor motor pendulum-type self-adaptive automatic variable speed drive assembly, which can not only automatically change gears without cutting off the driving force according to the change of driving resistance, but also solve the problem of The small change of motor torque and speed cannot meet the problem of road use under complex conditions, and it has better stability and smoothness when the slow transmission returns to release the variable speed elastic member, eliminating frustration and noise, which is conducive to further improving work efficiency. It has a better effect of energy saving and consumption reduction, and improves the service life, and is more suitable for light vehicles such as electric motorcycles
