The vehicle chassis comprises a left wheel module and a right wheel module which are transversely arranged along the vehicle chassis, and each of the left wheel module and the right wheel module comprises a steering knuckle which comprises an upper connecting end and a lower connecting end; the upper swing arm is rotationally connected with the upper connecting end of the steering knuckle; the lower swing arm is rotationally connected with the lower connecting end of the steering knuckle, the lower swing arm of the left wheel module transversely crosses the longitudinal center line of the vehicle chassis, the lower swing arm of the right wheel module transversely crosses the longitudinal center line of the vehicle chassis, and the lower swing arm of the left wheel module transversely crosses the longitudinal center line of the vehicle chassis. And the lower swing arm of the left wheel module and the lower swing arm of the right wheel module are partially overlapped in the transverse direction. And the lower swing arm is lengthened, so that the change of the inclination angle of the wheels can be better controlled, and the running stability of the logistics vehicle is improved. In addition, the left lower swing arm and the right lower swing arm are partially overlapped in the axial direction, so that the small unmanned logistics vehicle is more compact in structure and small in occupied space under the limitation of the narrow width.

    本公开涉及一种车辆底盘及无人物流车,包括沿车辆底盘横向设置的左轮模组和右轮模组,所述左轮模组和右轮模组均包括:转向节,包括上连接端和下连接端;上摆臂,所述上摆臂与所述转向节的上连接端转动连接;下摆臂,所述下摆臂与所述转向节的下连接端转动连接,其中,所述左轮模组的下摆臂横向越过所述车辆底盘的纵向中心线,所述右轮模组的下摆臂横向越过所述车辆底盘的纵向中心线,使所述左轮模组的下摆臂与所述右轮模组的下摆臂在横向上部分重叠。加长设置的下摆臂,能够更好地控制车轮倾角的变化,提升物流车运行时的稳定性。另外,左下摆臂和右下摆臂在轴向上部分重叠,使小型无人物流车在较窄宽度的限制下,使其结构更加紧凑且占用空间少。
