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.

    本申请提供一种电驱桥总成及车辆,电驱桥总成用于车辆,包括管式桥壳、轮边减速机构、驱动电机、编码器和电机制动器;轮边减速机构与管式桥壳端口固定连接,包括输入端和输出端,输入端与驱动电机的输出端连接,驱动电机为轮边减速机构提供动力输入,输出端与轮毂连接,通过轮毂带动车轮运转;驱动电机与编码器、电机制动器连接,编码器采集驱动电机的信号并反馈到车辆的控制器中,控制器根据编码器采集到的信号控制驱动电机工作,电机制动器通过将驱动电机中的电机主轴抱死实现车轮的驻车制动和紧急制动,驱动电机、编码器和电机制动器都位于管式桥壳内部。所述电驱桥总成,用管式桥壳代替了其他形状各异的桥壳,结构简单,降低了成本。
