The invention relates to the technical field of suspension rear axle mechanisms, in particular to an electric automobile suspension rear axle mechanism which comprises a rear axle speed reducer, axle housings are fixedly installed on the two sides of the rear axle speed reducer respectively, a brake drum is fixedly installed on the outer side of each axle housing, and a hub is fixedly installed on the outer side of each brake drum. Suspension half-shaft mechanisms are arranged between the hubs and the brake drums, guide arms are fixedly installed on the upper sides of the inner walls of the two brake drums, damping supports are fixedly installed at the upper ends of the guide arms, damper mechanisms are arranged at the upper ends of the damping supports, a buffer frame is arranged at the position, located at the upper end of the axle housing, of the rear axle speed reducer, and a suspension frame mechanism is arranged at the upper end of the buffer frame. The suspension axle shaft convenient to disassemble and maintain is adopted, compared with a traditional axle shaft, the suspension axle shaft does not need to bear impact force from tires, and the axle housing is responsible for bearing all bending force. The buffering mechanism and the shock absorber mechanism are matched to conduct shock absorption on the vehicle, force unloading can be conveniently conducted on the vehicle in multiple directions in the running process, and therefore more stable driving is achieved.
本发明涉及悬浮后桥机构技术领域,尤其涉及一种电动汽车悬浮后桥机构,包括后桥减速器,后桥减速器两侧分别固定安装有桥壳,每个桥壳外侧均固定安装有制动鼓,每个制动鼓外侧均固定安装有轮毂,轮毂与制动鼓之间设有悬浮半轴机构,两个制动鼓内壁上侧均固定安装有导臂,导臂上端固定安装有减震支架,减震支架上端设有减震器机构,后桥减速器位于桥壳上端设有缓冲架,缓冲架上端设有悬挂架机构。本发明采用便于拆卸维护的悬浮半轴,相比较传统半轴无需承受来自轮胎的冲击力,桥壳负责承受全部弯曲力。通过缓冲机构与减震器机构配合对车辆进行减震,便于车辆在行驶过程中在多个方向进行卸力,以此实现更加平稳地驾驶。
