The invention aims to provide a small electric trailer with a small turning radius. The small electric trailer comprises a trailer head, a carriage and a connecting mechanism for connecting the trailer head with the carriage, and is characterized in that the trailer head is only provided with a pair of driving wheels for driving the trailer head to advance and a driving motor for driving the driving wheels to rotate; the connecting mechanism is composed of a main frame connected to the tail end of the trailer head and an auxiliary frame connected to the front end of the carriage, and the mainframe is connected with the auxiliary frame through a vertical rotating shaft; the main frame is provided with a vertical transmission shaft through a bearing, and the upper portion of the transmission shaft is in transmission connection with a steering column of the trailer head through a chain. An arc-shaped gear part is arranged at the front end of the auxiliary frame and is in transmission connection with the lower portion of the transmission shaft through a gear pair. According to the small electric trailer, a steering system of a traditional automobile is changed, turning with the smallradius is achieved in a low-cost mode, and the small electric trailer is quite suitable for sanitation vehicles and other vehicles which are small in vehicle body and often run on narrow road sections.

    本发明的目的是提出一种转弯半径小的小型电动拖挂车。本发明的小型电动拖挂车包括车头、车厢及连接车头与车厢的连接机构,关键在于,所述车头仅设有用于驱动车头前进的一对驱动轮,以及用于使驱动轮转动的驱动电机;所述连接机构由连接于车头尾端的主架、连接于车厢前端的副架组成,所述主架与副架通过垂直转轴连接;所述主架通过轴承安装有垂直的传动轴,所述传动轴的上部通过链条与车头的转向柱传动连接;所述副架的前端设有弧形的齿轮部,所述齿轮部通过齿轮副与传动轴的下部传动连接。本发明的小型电动拖挂车改变了传统汽车的转向系统,以低成本的方式实现了较小半径的转弯,非常适合于环卫车等车体较小、经常在狭窄路段行驶的车辆。
