Centrally-mounted type manual/automatic integrative intellectualized self-adapting transmission sensing electrically-driven automatic speed changer

Abstract

The invention discloses a centrally-mounted type manual / automatic integrative intellectualized self-adapting transmission sensing electrically-driven automatic speed changer which comprises a main drive motor, a gearbox body, a shift driving shaft, a shift driven shaft and a gear shifting drum and also comprises a self-adapting transmission device, an automatic control system and a manual gear shifting system. The speed changer adopts a centrally-mounted structure; when a vehicle runs normally, a controller controls the gear shifting drum automatically to drive a servomotor to shift up or shift down automatically according to the running resistance and the intention of a driver, so that the optimal matching of current and a gear is achieved; when the resistance is changed, a gear shiftingmotion and a gear shifting gear are determined according to a torque-rotational speed change, and the optimal matching of the actual torque-rotational speed, the magnitude of the current and the gearis achieved, so that the drive motor always keeps favorable steady-state and high-efficiency running; and the invention can also switch automatic gear shifting to a manual gear shifting system according to an actual condition, and a gear shifting switch inputs a gear command to the controller and controls the drive motor and the gear shifting drum to drive the servomotor to realize manual gear shifting.

Description

technical field [0001] The invention relates to a power and transmission device of an electric vehicle, in particular to a mid-mounted manual automatic integrated intelligent self-adaptive transmission sensor electric drive automatic transmission. Background technique [0002] Electric vehicles are widely used in urban and rural roads due to their advantages of low price, lightness and flexibility, energy saving, good environmental protection and fast driving. [0003] In the prior art, electric bicycles basically control the speed by directly controlling the current through the speed control handle or the accelerator pedal. The operation of the handle or the accelerator pedal depends entirely on the driver's operation, which often causes the operation to not match the driving conditions. As a result, the motor runs unstable and stalled. [0004] In an electric vehicle, the transmission device is operated and controlled by the rider only based on experience without knowing ...

Problems solved by technology

[0007] In view of this, the present invention provides a mid-mounted automatic manual automatic transmission with intelligent self-adaptive transmission sensor and electric drive, which partially excludes the influence of the driver's subjective consciousness on the operation, and can automatically detect, correct and eliminate the driver's influence on complex road sections. It can adapt to the change of driving resistance and automatically adjust the current and vehicle speed to solve the problem that the electric vehicle determines the power supply current through the change of torque-speed and meets the problem of road use under complex conditions.
