The invention discloses a tractor hybrid electric drive axle, and relates to the technical field of electric drive axles, the tractor hybrid electric drive axle comprises an electric drive axle body, transmission shafts are arranged at the two ends of the interior of the electric drive axle body, a shell is fixedly mounted on the surface of the electric drive axle body, and a motor is fixedly mounted on the surface of the shell; a limiting block A is fixedly mounted on the surface of the electric drive axle body, a limiting frame is slidably connected into the limiting block A, and a limiting rod A is fixedly mounted in the limiting block A. A connecting plate drives a limiting rod B to slide upwards on the surface of a limiting rod A and in a limiting block A, a protection plate can also drive a protection pad to move upwards, and at the moment, a spring A can provide downward supporting force for a limiting frame and a bottom plate through the limiting rod B and the connecting plate; therefore, the effect of buffering and unloading the jacking force of stones or other hard objects is achieved, and the situation that the stones or other hard objects directly impact a motor, an electric drive axle body or a shell to damage the motor, the electric drive axle body or the shell is avoided.

    本发明公开了一种牵引车混动电驱动桥,涉及电驱动桥技术领域,包括:电驱动桥体,所述电驱动桥体的内部两端设置有传动轴,所述电驱动桥体的表面固定安装有壳体,所述壳体的表面固定安装有电机,所述电驱动桥体的表面固定安装有限位块A,所述限位块A的内部滑动连接有限位架,所述限位块A的内部固定安装有限位杆A。本发明通过连接板带动限位杆B在限位杆A的表面和限位块A的内部向上滑动,而防护板也会带动防护垫向上移动,此时弹簧A会通过限位杆B和连接板给限位架以及底板提供向下的支撑力,从而对石块或其他坚硬物体顶起的力进行缓冲卸力的效果,从而防止石块或其他坚硬物体直接撞击电机、电驱动桥体或壳体使其受损的情况发生。
