摘要：In this paper, the force analysis of the driving axle and the whole of the vehicle is carried out. By analyzing and comparing the relationship between the driving force provided by the motor, the load force of the driving axle before and after the vehicle, and the resistance of the vehicle's climbing slope, the influence of the uneven distribution of the driving axle load before and after the vehicle on the maximum climbing gradient of the vehicle is discussed. The method of balancing the driving axle load before and after by changing the relative position of the center of mass in a multi-drive electric vehicle with a certain motor power is proposed. On this basis, the feasibility of changing the relative centroid position of the vehicle to improve the maximum climbing gradient is verified by an example calculation, which provides a reference for the calculation of vehicle modification.
