The invention relates to a distributed motor drive axle which comprises an axle housing, two power assemblies and two rims, the two power assemblies are symmetrically arranged on the two sides of the central axis of the axle housing in the first direction, each power assembly comprises a motor, a first speed reducer, a brake and a second speed reducer which are sequentially arranged, the first speed reducer is in transmission connection with the motor, and the second speed reducer is in transmission connection with the brake. The second speed reducer is in transmission connection with the first speed reducer, the rim is used for installing wheels, the second speed reducer and the brake are located on the inner side of the rim, and the brake is used for controlling the rim to decelerate or stop; the first speed reducer and the second speed reducer are adopted for cooperative speed reduction, a differential mechanism used in the related technology is omitted, and the transmission efficiency is effectively improved; meanwhile, distributed driving is achieved, and the rotating speed and torque of the rim can be controlled more conveniently; and the second speed reducer and the brake are directly arranged in the rim, so that the space utilization rate of the rim is increased.
本发明涉及一种分布式电机驱动桥,包括桥壳、两个动力总成和两个轮辋,两个动力总成沿第一方向对称布置于桥壳的中心轴线两侧,每个动力总成包括依次设置的电机、第一减速器、制动器和第二减速器,第一减速器与电机传动连接,第二减速器与第一减速器传动连接,轮辋用于对车轮安装,第二减速器与制动器均位于轮辋的内侧,制动器用于控制轮辋减速或停止;本申请通过采用第一减速器和第二减速器进行协同减速,省去相关技术中使用到的差速器机构,有效地提升了传动效率;同时实现分布式驱动,可以更方便地控制轮辋的转速和扭矩;且通过将第二减速器与制动器直接布置在轮辋内,提高了轮辋的空间利用率。
