The invention discloses a truss combined type power drive axle, and relates to the technical field of drive axle design. The truss combined type power drive axle comprises a left half axle provided with wheels, a right half axle provided with wheels, and a drive axle body which is connected with the left half axle and the right half axle simultaneously and drives the wheels to rotate. The drive axle body comprises a power box provided with a driving device, a first axle housing and a second axle body which are arranged at the left end and the right end of the power box respectively, and multiple connecting trusses which are fixedly connected with the first axle housing and the second axle housing; the truss combined type power drive axle also comprises a motor, a differential mechanism and a transmission which are mounted in the power box and are uniformly distributed around the central axis of the power box, so that the integral mass center of the drive axle is close to the rotation axis of the wheel. The axle and the power device are innovatively combined, and a traditional front and rear axle arrangement structure is replaced. The offset distance between the axle mass center and the wheel rotation axis is small, the structural stability of the drive axle is improved, and the problems that the drive axle leaks oil and is prone to damage due to center-of-gravity offset are solved.

    本发明公开了一种桁架组合式动力驱动桥,涉及驱动桥设计技术领域。包括安装有车轮的左半桥、安装有车轮的右半桥,以及同时连接左半桥和右半桥并带动车轮转动的驱动桥体,所述驱动桥体包括装载有驱动装置的动力箱、分别设置于动力箱左右两端的第一桥壳和第二桥体,以及多个固定连接第一桥壳和第二桥壳的连接桁架;还包括安装于动力箱中的电机、差速器、变速器,所述电机、差速器、变速器环绕动力箱的中线轴线均匀分布设置,以使得驱动桥整体质心靠近车轮旋转轴线。本发明使桥与动力装置的创新结合,取代传统前后桥设置结构。使桥质心对车轮旋转轴线的偏距较小,提高驱动桥结构稳定性,避免驱动桥出现漏油、重心偏置易损的问题。
