The invention provides a four-wheel drive system, a control method and a vehicle with the four-wheel drive system, and the four-wheel drive system comprises a power input shaft, a power output shaft and a power output shaft, the axis of the motor shaft is parallel to the axis of the power input shaft; the front axle output shaft is sleeved on the power input shaft; and the rear axle output shaft and the power input shaft are coaxially arranged. A power input shaft is provided with a first driving gear and a second driving gear, the first driving gear is connected with a first gear train, the second driving gear is connected with a second gear train, one end of a motor shaft is connected with an adjusting motor, the power input shaft is sleeved with a front axle output shaft, and the front axle output shaft is connected with the first gear train. The rear axle output shaft is connected with the second wheel train, so that driving force is effectively and equally distributed to four wheels, the driving force distributed to each wheel is reduced to be half of the original driving force, and the driving slip boundary of the vehicle and the adaptive capacity of the vehicle to a low-attachment road surface are effectively improved.

    本发明提供了一种四轮驱动系统、控制方法及具有其的车辆,四轮驱动系统包括:动力输入轴,动力输入轴一端与发动机连接;电机轴,电机轴的轴线与动力输入轴的轴线平行的设置;前桥输出轴,前桥输出轴套设与动力输入轴上;后桥输出轴,后桥输出轴与动力输入轴同轴的设置。本申请将动力输入轴设有第一主动齿轮与第二主动齿轮,并将第一主动齿轮与第一轮系连接,第二主动齿轮与第二轮系连接,电机轴一端与调节电机连接,前桥输出轴套设于动力输入轴上,前桥输出轴与第一轮系连接,后桥输出轴与第二轮系连接,有效地将驱动力平分到四个车轮上,使得每个车轮分配的驱动力就降低为原先的一半,有效地提高车辆的驱动打滑边界和对低附路面的适应能力。
