The invention discloses a vehicle chassis and a tractor thereof. The vehicle chassis comprises a frame; the front wheels on the frame on each side are connected with the steering device on the corresponding side to achieve synchronous and independent rotation, the rear wheels on the frame on each side are arranged at the output end of a reduction gearbox, and a driving motor is arranged at the input end of the reduction gearbox. The two sets of steering wheels are arranged, an independent electronic steering mode is adopted, the steering angle limitation caused by a steering axle structure is avoided, the smaller turning radius can be achieved, and the driving flexibility of the whole vehicle is improved; meanwhile, a whole vehicle power system adopts two high-power motors which are independent left and right in mechanical structure, the rotating speeds of the left and right motors are controlled through a double-drive control system, the speeds of the left and right driving wheels are consistent during straight movement, and the left and right motors output different rotating speeds respectively according to steering angles during turning, so that the purpose of driving wheel differential speed is achieved.

    本发明公开了一种车辆底盘及其牵引车,包括车架;一对前轮,每侧车架上的所述前轮与对应侧的转向装置连接,以实现同步独立转动,以及一对后轮,每侧车架上的所述后轮设置在减速箱的输出端,所述减速箱的输入端设置有驱动电机。本发明通过在设置两组转向轮,采用独立电子转向方式,避免了转向桥结构带来的转向角度限制,能够达到更小的转弯半径,提高了整车行驶的灵活性;同时,整车动力系统采用两件大功率电机,机械结构上左右独立,通过双驱控制系统控制左右测电机转速,直行时速度左右驱动轮速度一致,转弯时根据转向角度,左右电机分别输出不同的转速,达到驱动轮差速的目的。
