Abstract

The invention provides a double-motor skidproof differential drive axle used in electric automobiles, which comprises two driving motors, a speed reducer and an output axle which is connected with theThe invention provides a double-motor skidproof differential drive axle used in electric automobiles, which comprises two driving motors, a speed reducer and an output axle which is connected with the speed reducer. The two driving motors are arranged face to face in the middle of the driving axle and connected into a whole through the shell of the speed reducer. The power output by the two drivinspeed reducer. The two driving motors are arranged face to face in the middle of the driving axle and connected into a whole through the shell of the speed reducer. The power output by the two driving motors converges together and flows into the speed reducer; and then the power further drives the left and the right wheels of the electric automobile to rotate through the output axle which is conng motors converges together and flows into the speed reducer; and then the power further drives the left and the right wheels of the electric automobile to rotate through the output axle which is connected with the speed reducer. The driving motors and the speed reducer can be arranged in an engine chamber to achieve compact structure and save space. Simultaneously, in order to solve the problem oected with the speed reducer. The driving motors and the speed reducer can be arranged in an engine chamber to achieve compact structure and save space. Simultaneously, in order to solve the problem of skidding, a skidproof differential device is also arranged in the speed reducer.f skidding, a skidproof differential device is also arranged in the speed reducer.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and more specifically relates to a dual-motor anti-slip differential drive axle suitable for driving electric vehicles. Background technique [0002] Due to the increasingly tense global energy sources, electric vehicles with high efficiency, energy saving and environmental protection have become the trend of future automobile development. Compared with electric vehicles driven by single motors, electric vehicles using dual-motor independent wheel drive (hereinafter referred to as dual-motor drive) schemes have many advantages, such as simplifying the mechanical transmission system, improving drive efficiency, and making full use of the on-board energy to increase the mileage; and the compact structure improves the space utilization of the car; the most critical thing is that the dual-motor drive scheme can achieve electronic differential speed by independently adjusting the speed of the two driv...

Problems solved by technology

At the same time, when driving, the vehicle is mainly driven by the motor of the wheel with a high adhesion coefficient relative to the road surface, which wastes the driving power of the motor on the side of the slipping wheel, and then if the vehicle is in a climbing state or encounters certain obstacles , the vehicle is likely to be impassable, which is not as good as a single-motor electric vehicle with a limited slip differential or a conventional vehicle
