The invention relates to the technical field of vehicles, in particular to an electric drive axle and a vehicle. The electric drive axle comprises an axle housing, two motors, two first-stage speed reducers, two parking brakes, two half shafts and two hub speed reducers, and the two motors and the two first-stage speed reducers are all arranged in the central axle housing. The input end of the first-stage speed reducer is connected with a motor shaft; the parking brake comprises a brake shell and a brake assembly arranged in the brake shell, and the brake assembly can brake the output end of the first-stage speed reducer. One end of the half shaft is connected with the output end of the first-stage speed reducer; the input end of the hub reduction gear is in transmission connection with the other end of the half shaft, and the output end of the hub reduction gear is connected with the hub. The device is high in reliability and can be suitable for existing tire sizes, and a scheme capable of installing the service brake and the parking brake at the same time is provided.

    本发明涉及车辆技术领域,尤其涉及一种电驱动车桥及车辆。电驱动车桥包括桥壳、两个电机、两个一级减速器、两个驻车制动器、两个半轴以及两个轮边减速器,两个电机和两个一级减速器均设置于中央桥壳内;一级减速器的输入端与电机轴连接;驻车制动器包括制动器壳体和设置于制动器壳体内的制动组件,制动组件能够对一级减速器的输出端进行制动;半轴的一端与一级减速器的输出端连接;轮边减速器的输入端与半轴的另一端传动连接,轮边减速器的输出端与轮毂连接。本发明可靠性较高,能够适用于现有的轮胎尺寸,且提供了一种能够同时安装行车制动器和驻车制动器的方案。
