    摘要:

    在傳統(tǒng)重型車輛上，增加一套由泵和馬達(dá)等組成的輪轂馬達(dá)液壓驅(qū)動(dòng)系統(tǒng)，使其由原來的兩輪驅(qū)動(dòng)變成四輪驅(qū)動(dòng)，對該系統(tǒng)的結(jié)構(gòu)原理與工作模式進(jìn)行了分析，研究建立了該系統(tǒng)的動(dòng)力學(xué)理論方程， 使用Matlab/Simulink和 AMESim軟件分別建立系統(tǒng)的機(jī)械動(dòng)力系統(tǒng)和液壓系統(tǒng)模型，并進(jìn)行車輛牽引力及爬坡性能的聯(lián)合仿真。仿真結(jié)果表明：使用液壓輪轂驅(qū)動(dòng)系統(tǒng)后，車輛牽引力提高了13.4%，爬坡度提高了14.4%，整車通過性得到明顯提高。

    Abstract:

    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.
