The invention discloses a trailer with a motor power auxiliary driving device. The trailer comprises a frame, walking wheels and a driving module. The driving module comprises a driving motor and a driving wheel, the driving wheel is connected with an output shaft of a reduction gearbox of the driving motor, the driving motor is fixed to the carrier plate, the bottom of the carrier plate is connected with the lower end of the elastic assembly, and the upper end of the elastic assembly is connected with the frame through the mounting assembly. And the lower edge of the driving wheel is lower than a plane formed by the lower edges of the walking wheels. Through the design that the elastic assemblies are arranged and the driving wheels are lower than the plane of the walking wheels, the friction force of the driving wheels is effectively increased, and the loading capacity of the trailer is enhanced. By arranging the rotatable mounting assembly, the trailer can freely choose to lift up or put down the driving wheels according to use scenes. The handle and the kidney-shaped groove in the handle drive the positioning pin to be inserted and pulled out, so that the function of folding the driving wheel with one hand is achieved, and operation is more convenient.
本发明公开了具有电机动力辅助驱动装置的拖车,包括:车架、行走轮以及驱动模块;所述驱动模块包括驱动电机以及驱动轮,所述驱动轮和驱动电机的减速箱输出轴连接,驱动电机固定在载板上,载板的底部和弹性组件的下端连接,弹性组件的上端通过安装组件与车架连接,所述驱动轮的下缘低于行走轮下缘所构成的平面。本发明通过弹性组件以及将驱动轮低于行走轮平面的设计有效的增大了驱动轮的摩擦力,加强了拖车的载重能力。通过设置可转动的安装组件使得拖车可以根据使用场景自由选择将驱动轮抬起或者放下。通过把手以及把手上的腰形槽带动定位销的插拔实现了单手收房驱动轮的功能,使得操作更加方便。
