Problems solved by technology
[0002] When electric vehicles drive in rainy and snowy weather, tires will slip when turning or braking. If the speed is fast, it is easy to cause traffic accidents and threaten life safety.
The existing anti-skid technology is mainly realized through the ESP system, but the ESP system is mostly installed on the car, and the installation of the electric car will greatly increase the cost
Moreover, the braking device of the ESP system needs to be installed on all driven wheels, and the circuit is complicated

The invention relates to the field of electric vehicle accessories, in particular to a drive axle for an electric vehicle. The drive axle for the electric vehicle comprises a motor and a reduction gearbox. The number of half drive axle bodies is two. The two half drive axle bodies are located on the left side and the right side of a planet gear respectively. The half drive axle body located on the right side of the planet gear comprises a driving half drive axle body and a driven half drive axle body which are connected through a coupler. The driven half drive axle body is sleeved with a braking ring. According to the drive axle for the electric vehicle, the rotating speed of the half drive axle bodies can be increased through an acceleration gear assembly, the rotating speed of the half drive axle bodies can be decreased through the braking ring, the purposes that a vehicle body is balanced and side sliding is prevented are achieved by adjusting the rotating speed of the half drive axle bodies, the safety coefficients are increased, and the risk is prevented from happening.
Description
technical field [0001] The invention relates to the field of electric vehicle accessories, in particular to an electric vehicle drive axle. Background technique [0002] When electric vehicles drive in rainy and snowy weather, tires will slip when turning or braking. If the vehicle speed is fast, it is easy to cause traffic accidents and threaten the safety of life. The existing anti-skid technology is mainly realized through the ESP system, but the ESP system is mostly installed on the car, and the installation of the electric car will greatly increase the cost. Moreover, the braking device of the ESP system needs to be installed on all driven wheels, and the circuit is complicated. Contents of the invention [0003] The purpose of the present invention is in order to solve above-mentioned problem, has designed a kind of electric vehicle driving axle. The specific design scheme is: [0004] An electric vehicle drive axle, comprising a motor and a reduction box, the mot...
