The invention provides a distributed driving motor axle for a heavy commercial vehicle, and relates to the technical field of power systems. The axle comprises a power assembly, an axle housing, a hub reduction gear and a hub assembly. The two power assemblies are installed on the axle housing through supporting structures and are symmetrical about the front and back of the axle housing. The output end of any power assembly is connected with the corresponding hub reduction gear, so that power is transmitted to the corresponding hub assembly. A power assembly of the whole vehicle is integrated on the axle, so that the arrangement space of the whole vehicle is released, and the weight and the gravity center of the whole vehicle are reduced; the gravity center of the whole bridge is on the central axis of the bridge, the structural reliability is high, and low-frequency impact caused by eccentricity of the gravity center of the whole bridge is effectively reduced; according to the mounting structure, decoupling of bearing and transmission is achieved, work of a motor and a transmission system is not affected when the axle housing bears, and reliability is improved; according to the structure, the power assembly can be replaced under the condition that an axle is not detached from a vehicle under the condition that the whole vehicle is assembled, and maintenance is more convenient.

    本发明提供一种用于重型商用车的分布式驱动电机桥,涉及动力系统技术领域。本发明包括动力总成、桥壳、轮边减速器和轮毂总成;两个所述动力总成均通过支撑结构安装在桥壳上,并关于桥壳的前后对称;任一所述动力总成输出端与对应的轮边减速器相连接,实现将动力传递给对应的轮毂总成。通过将整车的动力总成集成在桥上,释放了整车的布置空间,降低了整车重量和重心;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;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;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。
