The invention provides an electric drive axle assembly and a vehicle, the electric drive axle assembly is used for the vehicle, and the electric drive axle assembly comprises a tubular axle housing, a hub speed reduction mechanism, a driving motor, an encoder and a motor brake; the hub speed reduction mechanism is fixedly connected with a port of the tubular axle housing and comprises an input end and an output end, the input end is connected with the output end of the driving motor, the driving motor provides power input for the hub reduction mechanism, the output end is connected with the hub, and the hub drives the wheels to run; the driving motor is connected with the encoder and the motor brake, the encoder collects signals of the driving motor and feeds the signals back to a controller of the vehicle, the controller controls the driving motor to work according to the signals collected by the encoder, and the motor brake locks a motor main shaft in the driving motor to achieve parking braking and emergency braking of wheels. The driving motor, the encoder and the motor brake are all located in the tubular axle housing. According to the electric drive axle assembly, axle housings in different shapes are replaced by the tubular axle housing, the structure is simple, and the cost is reduced.
Description
technical field [0001] The present application relates to the technical field of vehicles, in particular to an electric drive axle assembly and a vehicle. Background technique [0002] Existing electric drive axles have different vehicle axle structures, but most of them are complex in structure and high in cost, and expensive electric drive axles increase the cost of the vehicle at the same time. And the drive motors in the existing electric drive axle are all installed outside the axle housing, which are easily damaged and destroyed, and also bring hidden dangers to the safety of the vehicle itself, reducing the service life of the vehicle. Contents of the invention [0003] The present application provides an electric drive axle assembly, which solves the problems of complex structure and high cost of the existing electric drive axle. In addition, the drive motor and the encoder are installed inside the axle housing, so that the drive motor and the encoder are not easi...
