The invention relates to the technical field of vehicles, and discloses an integrated electric drive axle and a vehicle, the integrated electric drive axle comprises a first motor and a parking brake, the parking brake comprises a brake shell, an input shaft, a parking gear ring and a piston, the input shaft is connected with the first motor, the parking gear ring is arranged on the periphery of the input shaft in a sleeving mode, and the parking gear ring and the input shaft rotate synchronously; the piston is arranged in the braking shell, the piston and the braking shell are in limiting fit in the direction of relative rotation around the axis of the input shaft, the parking gear ring is provided with a first braking spline, the piston is provided with a second braking spline, and the piston can move in the axial direction of the input shaft so that the parking brake can be switched between a first parking state and a first parking release state. In the first parking state, the first braking spline is meshed with the second braking spline; in the first parking release state, the first brake spline and the second brake spline are separated from each other. The problem that in the prior art, the parking reliability of a parking brake is poor can be solved.

    本发明涉及车辆技术领域,公开一种集成电驱动桥及车辆,集成电驱动桥包括第一电机和驻车制动器,驻车制动器包括制动壳、输入轴、驻车齿环和活塞,输入轴与第一电机相连,驻车齿环套设于输入轴的外周,驻车齿环和输入轴同步转动,活塞设于制动壳内,活塞与制动壳在绕输入轴的轴线相对转动的方向限位配合,驻车齿环设有第一制动花键,活塞设有第二制动花键,活塞可沿输入轴的轴向移动,以使驻车制动器在第一驻车状态和第一驻车解除状态之间切换,在第一驻车状态下,第一制动花键和第二制动花键相啮合;在第一驻车解除状态下,第一制动花键和第二制动花键相互分离。本发明能解决相关技术中,驻车制动器的驻车可靠性较差的问题。
