Abstract

The drive axle device comprises an electric power assembly, the electric power assembly comprises a wheel assembly, a motor and a brake, the wheel assembly comprises wheels, the wheels are provided with containing spaces, the motor is contained in the containing spaces and is in transmission connection with the wheels to drive the wheels to rotate, and the brake is in transmission connection with the wheels to brake the wheels. The motors are arranged in the wheels to achieve distributed driving, the brakes are arranged in the middle of the drive axle device, the structure is simple, the development cost and difficulty of a mechanical braking system can be reduced, and then the problems that due to an existing driving mode, the drive axle device is complex in structure, and the development cost and difficulty of the drive axle device are high are solved.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a driving axle device and a vehicle. Background technique [0002] The drive axle device is an important part of the vehicle. It is a mechanism located at the end of the drive train that can change the speed and torque from the transmission and transmit them to the drive wheels. [0003] The current drive axle device adopts a centralized drive, that is, two motors and gear reduction mechanisms are integrated into the main reduction assembly, which is arranged in the middle of the drive axle. A driving motor passes through the gear reduction mechanism through the differential and then transmits to the wheel edge structures on both sides. Further, the wheels are driven. This driving method makes the structure of the drive axle device complex, and the development cost and difficulty of the drive axle device are relatively high. Contents of the invention [0004] Ba...
