An electric automobile drive axle assembly comprises a concave axle frame, double-wishbone suspensions installed on the two sides of the axle frame, an electric drive mechanism arranged on the axle frame and connected and matched with the double-wishbone suspensions, and a transversely-arranged plate spring arranged on the axle frame, wherein the two ends of the transversely-arranged plate spring are connected with the double-wishbone suspensions respectively. The arrangement space is provided for the electric drive mechanism through the axle frame shaped like the Chinese character'ao 'and the transverse plate spring arranged on the axle frame, and the shock absorbers in the double-wishbone suspensions installed on the two sides of the axle frame are matched with the transverse plate spring to provide an elastic system meeting the requirement for the double-wishbone suspensions. Therefore, the arrangement requirements of an axle electric drive mechanism and a matched double-wishbone suspension are met, a novel matched drive axle assembly is provided for a low floor, a low chassis and an electric automobile with the requirement for the flatness of the chassis, the purposes of being compact in overall structure and small in occupied space are achieved, the design is novel and unique, the structure is compact and simple, and the cost is low. Manufacturing and mounting are easy and convenient, and popularization and application value is high.

    一种电动汽车驱动桥总成,包括凹字形车桥架、安装在车桥架两侧的双横臂悬架、设置在车桥架上且与双横臂悬架连接配合的电驱机构、以及设置在车桥架上且两端分别与双横臂悬架连接的横置板簧。本发明通过凹字形的车桥架以及设置在车桥架上的横置板簧为电驱机构提供了布置空间,而安装在车桥架两侧的双横臂悬架中的减振器与横置板簧配合后为双横臂悬架提供了满足需求的弹性系统,从而满足了车桥电驱机构及其匹配双横臂悬架的布置要求,为低地板、低底盘以及对底盘有平整度要求的电动汽车提供了一种新颖适配的驱动桥总成,实现了整体结构紧凑、占用空间小的目的,其设计新颖独特、结构紧凑简单,制作安装简单方便,极具推广和应用价值。
