The invention discloses a vehicle connecting bridge device and a pallet truck. The vehicle connecting bridge device comprises a vehicle body; a connecting bridge frame which is arranged on the vehicle body, wherein the connecting bridge frame swings up and down with the central axis of the vehicle body as the axis, and driving wheels with steering and driving functions are symmetrically arranged on the two sides of the connecting bridge frame; a swing shaft is arranged on the central axis of the connecting bridge frame in a penetrating mode, the two ends of the swing shaft are connected with the vehicle body, and damping springs are arranged at the two ends of the connecting bridge. The connecting bridge frame is arranged on the vehicle body through the swing shaft to form a swing bridge structure, and when the vehicle runs to a road surface with poor road conditions, the swing bridge swings leftwards and rightwards to adapt to wheel surfaces so that the vehicle body part is kept balanced and stable, stress on the driving wheels on the two sides is uniformly distributed, excessive abrasion of the wheels is reduced, and the service life of the wheels is prolonged; meanwhile, the driving motor and the steering motor are arranged on the wheels on the two sides respectively so that the wheels on the two sides have independent driving and steering kinetic energy respectively.

    本发明公开了一种车辆连桥装置及托盘车,包括,车体;连桥架,其设置在车体上,所述连桥架以车体中轴线为轴心上下摆动,所述连桥架两侧对称设置有具有转向和驱动功能的驱动轮;其中:所述连桥架中轴线上贯穿设置有摆动轴,所述摆动轴两端与车体连接,所述连桥架两端设置有减震弹簧。本发明将连接桥通过摆动轴设置在车体上,进而形成摆动桥结构,当车辆行驶至路况不良的路面时,摆动桥通过左右摆动来适应轮面,使得车体部分保持平衡稳定,并且使两侧的驱动轮受力均匀分布,降低了车轮的过度磨损,提高了车轮的使用寿命;同时,通过在两侧的车轮上分别设置驱动电机和转向电机,使得两侧的车轮分别具有独立的驱动和转向动能。
