The invention discloses a light-weight dual-motor distributed drive axle assembly. The light-weight dual-motor distributed drive axle assembly comprises an axle shell, a half-shaft module and a fixed-speed-ratio power module. The half-shaft modules are arranged corresponding to the two ends of the axle shell. The fixed-speed-ratio power modules are arranged corresponding to the two sides of the axle shell, and transmission ends corresponding to the half-shaft modules are arranged on the fixed-speed-ratio power modules. The transmission ends are in transmission connection with the half-shaft modules at the two ends of the axle shell correspondingly. The fixed-speed-ratio power module is used for conducting transmission control on the half-shaft modules at the two ends of the axle shell through the transmission ends. The design of a transmission shaft and a differential mechanism can be canceled, then the dual-motor distributed design is matched, distributed motor coupling driving is achieved, the torque and power of a single motor are reduced, and by means of the highly integrated design of the fixed-speed-ratio speed reducer, the driving motor and the axle, the driving efficiency is improved. Therefore, the weight of the assembly and the occupied space of the axle are reduced, the power and the volume density are improved, and independent control over all the wheels is achieved.
本发明公开了一种轻量化的双电机分布式驱动桥总成,包括:车桥壳体、半轴模组和固定速比动力模组;半轴模组对应车桥壳体的两端设置;固定速比动力模组对应车桥壳体两侧设置,且固定速比动力模组上设有与半轴模组对应的传动端;传动端与车桥壳体两端的半轴模组分别传动连接;固定速比动力模组用于通过传动端对车桥壳体两端的半轴模组分别进行传动控制;本发明能够通过取消传动轴以及差速器的设计,进而配合双电机分布式的设计,实现分布式电机耦合驱动,降低了单个电机的转矩和功率,且配合固定速比减速器、驱动电机以及车桥之间的高度集成设计,进而降低了总成重量以及车桥空间占用,提高了功率及体积密度,实现了各轮的分别独立控制。
