Abstract

The present invention provides a bidirectional driving device of a main driving motor of an electric automobile. The bidirectional driving device comprises the main driving motor and a transmission assembly, the main driving motor comprises a front output shaft and a back output shaft, and the transmission assembly comprises a shaft sleeve flange, a driving pulley, a driving belt and a or a plurality of driven pulleys. The shaft sleeve flange is connected with the front output shaft, the driving pulley is connected with the back output shaft, and the one or the plurality of driven pulleys are connected with the driving pulley via the driving belt and is or are used to drive a or a plurality of vehicle-mounted functional part(s) to operate.

Description

technical field [0001] The invention mainly relates to the technical field of electric vehicle power, in particular to a bidirectional drive device for a main drive motor of an electric vehicle. Background technique [0002] At present, due to the serious pollution of the environment by internal combustion engine vehicles, pure electric vehicles, as a green new energy technology, have gradually attracted people's attention due to their zero emissions and low noise. However, pure electric vehicles also have many disadvantages. For example, the main drive motor of existing pure electric vehicles drives the speed reducer, gearbox and clutch in a unidirectional shaft transmission mode. Vehicle-mounted functional components such as electric-driven air-conditioning compressors, electric-driven water pumps, electric-driven vacuum pumps, hydraulic pumps, air compressors, etc. are all driven by separate motors. [0003] Since pure electric vehicles use on-board batteries, their capa...
