Problems solved by technology

[0002] Electric vehicles (BEV) refer to vehicles powered by vehicle-mounted power supplies, driven by motors to drive wheels, and meeting the requirements of road traffic and safety regulations. Because they have less impact on the environment than traditional vehicles, their prospects are widely optimistic. The drive of the car is generally driven by one drive motor or four hub motors. Electric vehicles using only one drive motor have disadvantages such as poor driving power and poor passability. The wheels of electric vehicles using four hub motors High integration and heavy weight make it extremely difficult to repair and replace

Abstract

The invention discloses an electric vehicle driving device which comprises a battery pack, a front driving motor, a rear driving motor, a driving motor controller, a front transmission shaft, a rear transmission shaft, a front axle limited slip differential, a rear axle limited slip differential, a front transmission semi-shaft, a rear transmission semi-shaft, a front wheel, a front wheel brake, a rear wheel, a rear wheel brake, an entire vehicle controller, an accelerator pedal sensor, a brake pedal sensor, a steering system sensor, an electronic gear sensor and a vehicle speed sensor. According to the invention, by adopting two driving motors for driving in a matched mode, the driving efficiency of the driving motors is greatly improved; and by adopting an integrated driving motor controller instead of a clutch device, mechanical devices of an electric vehicle are reduced, and the management control capability of a driver for switching a front-drive mode, a rear-drive mode and a four-drive mode is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of electric vehicles, in particular to the technical field of an electric vehicle driving device. 【Background technique】 [0002] Electric vehicles (BEV) refer to vehicles powered by vehicle-mounted power supplies, driven by motors to drive wheels, and meeting the requirements of road traffic and safety regulations. Because they have less impact on the environment than traditional vehicles, their prospects are widely optimistic. The drive of the car is generally driven by one drive motor or four hub motors. Electric vehicles using only one drive motor have disadvantages such as poor driving power and poor passability. The wheels of electric vehicles using four hub motors The integration is high and the weight is heavy, so it is extremely unfavorable for repair and replacement. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and to propose a...
