The invention belongs to the technical field of motor axles, and discloses a distributed driving motor axle for a heavy commercial vehicle, which comprises an assembling axle housing, a left power assembly and a right power assembly are mounted in the assembling axle housing, and the two power assemblies are mounted in the assembling axle housing through four supporting structures; the opposite faces of the two power assemblies are connected with hub reducers through output shafts. The power assemblies are installed on the assembling axle housing through the supporting structures, the two power assemblies are symmetrically installed on the front side and the rear side of the assembling axle housing correspondingly, the gravity center of the whole axle is located on the central axis of the axle, the structural reliability is high, and low-frequency impact caused by eccentricity of the gravity center of the whole axle is effectively reduced; meanwhile, decoupling of bearing and transmission is achieved through the mounting structure, work of a motor and a transmission system is not affected when the axle housing bears, and reliability is improved; and meanwhile, the power assembly can be replaced under the condition that the axle is not detached from the vehicle under the condition that the whole vehicle is assembled, so that the maintenance is more convenient.

    本发明属于电机桥技术领域,且公开了一种重型商用车用分布式驱动电机桥,包括装配桥壳,所述装配桥壳的内部安装有左右两个动力总成,两个所述动力总成均通过四个支撑结构安装于装配桥壳的内部,两个所述动力总成的相背面通过输出轴连接有轮边减速器。本发明通过个支撑结构将动力总成安装在装配桥壳上,两个动力总成分别对称安装于装配桥壳的前后两侧,使整桥重心在桥的中轴线上,结构可靠性高,有效的降低了由于整桥重心偏心带来的低频冲击;同时该安装结构实现了承载与传动的解耦,桥壳承载时不影响电机和传动系统工作,提高了可靠性;同时该结构在整车完成装配的条件下可以实现不从车上拆下桥的情况下更换动力总成,维修更方便。
