The invention belongs to the technical field of new energy vehicles, and discloses a distributed integrated motor axle for a new energy commercial vehicle, which comprises a cross beam mechanism, the two ends of the cross beam mechanism are both provided with wheel edge driving assemblies, and each wheel edge driving assembly comprises a speed reducer assembly, a brake assembly, a motor and a controller assembly. The speed reducer assembly comprises a first-stage speed reducer, a hub assembly and a hub reduction gear, and the brake assembly is arranged above the first-stage speed reducer; and the motor and controller assembly is fixed on the primary speed reducer. Through wheel edge integration of the motor, the electric controller and the speed reducer, the overall weight of the driving system is reduced, the overall arrangement space of the power system is saved, a power transmission chain is shortened, and the transmission efficiency is improved; through distributed driving, no inter-wheel differential and canceling of a spiral main reduction gear, the feedback capacity can be improved, and the running economy of the whole vehicle is improved.

    本发明属于新能源车技术领域,且公开了一种新能源商用车用分布式集成电机桥,包括横梁机构,所述横梁机构的两端均设置有轮边驱动总成,所述轮边驱动总成包含有减速器总成、制动器总成、电机及控制器总成,所述减速器总成包括一级减速器、轮毂总成和轮边减速器,所述制动器总成设置于一级减速器的上方;所述电机及控制器总成固定到一级减速器上。本发明中通过电机、电控、减速器的轮边集成,降低驱动系统整体的重量、节省动力系统整体的布置空间、缩短动力传动链、提高传动效率;本发明通过分布式驱动,无轮间差速器,取消螺旋主减齿轮,可以提升回馈能力,提高整车运行经济性。
