摘　　要：在传统重型车辆上,增加一套由泵和马达等组成的轮毂马达液压驱动系统,使其由原来的两轮驱动变成四轮驱动,对该系统的结构原理与工作模式进行了分析,研究建立了该系统的动力学理论方程,使用Matlab/Simulink和AMESim软件分别建立系统的机械动力系统和液压系统模型,并进行车辆牵引力及爬坡性能的联合仿真。仿真结果表明:使用液压轮毂驱动系统后,车辆牵引力提高了13.4%,爬坡度提高了14.4%,整车通过性得到明显提高。By adding a hydraulic propulsion system made up of pumps and motors primarily in a traditional heavy vehicle,it is changed to a four-wheel driven vehicle from a two-wheel driven vehicle.The principle of the system configuration and working modes were analyzed.The system dynamics equations were established.The whole vehicle system was modeled by a co-simulation method with Matlab/Simulink and AMESim software.The vehicle＇s traction force and climbing capacity was simulated and compared.The results showed that after using the hydraulic propulsion system,the vehicle traction force was increased by 13.4% and the climbing capacity was improved by 14.4%,which means the vehicle passability was also improved significantly.
