The invention belongs to the technical field of vehicle equipment, particularly relates to a light and simple crawler chassis double-electric-drive rear axle, and aims to solve the problem that an existing crawler chassis double-electric-drive rear axle lacks measures for cooling a direct current motor. The same drive axle connecting piece is arranged on the opposite sides of the two axle pipes, power half shafts are arranged in the two axle pipes correspondingly, and track drive discs are arranged at the ends, away from the drive axle connecting piece, of the two power half shafts correspondingly. According to the light and simple crawler chassis double-electric-drive rear axle, the direct-current motor running at high power can be subjected to targeted rapid cooling, heat generated by the direct-current motor is rapidly replaced through airflow flowing at high speed, and therefore heat accumulation of the direct-current motor is reduced, normal running of the direct-current motor is guaranteed, and the service life of the direct-current motor is prolonged. And the situation that the running power of the direct current motor is lost and even the service life is shortened due to high heat is avoided.

    本发明属于车辆设备技术领域,尤其是一种轻简履带底盘双电驱后桥,针对现有的履带底盘双电驱后桥上缺乏为直流电机进行降温的措施的问题,现提出以下方案,包括两个对称的桥管,两个所述桥管相对的一侧设置有同一个驱动桥连接件,且两个桥管内均设置有动力半轴,两个所述动力半轴远离驱动桥连接件的一端均设置有履带驱动盘。本发明公开的一种轻简履带底盘双电驱后桥可以实现对高功率运行的直流电机进行针对性快速降温,利用高速流动的气流快速的对直流电机产生的热量进行替换,从而减少了直流电机的热量积蓄,保证了直流电机的正常运行,避免了直流电机因高热而损失运行功率甚至是使用寿命降低的情况出现。
