The invention relates to a coaxial two-gear distributed electric drive bridge system without power interruption, and mainly solves the technical problems that an existing parallel-axis electric drive bridge is arranged in an offset cantilever manner and is easily damaged under a large impact load, and a single-motor coaxial electric bridge is limited in the aspect of torque output. The differential mechanism comprises a left driving motor and a left speed change unit which are symmetrically arranged, and a right driving motor and a right speed change unit which are symmetrically arranged, and the motors can be controlled through a TCU to achieve the differential function. The symmetrical coaxial electric drive bridge structure can overcome the cantilever problem of a parallel-axis electric drive bridge, and the bridge is uniformly distributed in the axial direction. Meanwhile, the double-intermediate-shaft structure and the planet row structure can improve the heavy-load torque transmission capacity of the heavy electric drive axle.

    本发明涉及一种同轴无动力中断的二挡分布式电驱桥系统,主要解决现有平行轴电驱桥偏置悬臂布置,容易在大冲击载荷下破坏,以及单电机同轴电桥在扭矩输出方面受限制的技术问题。本发明包括对称式设置的左驱动电机、左变速单元与右驱动电机、右变速单元,可通过TCU控制电机实现差速功能。对称式设计的同轴电驱桥结构,可以克服平行轴电驱桥的悬臂问题,桥沿轴向质量均匀分布。同时,双中间轴结构和行星排结构能够提高重型电驱桥重载传扭能力。
