在对车辆爬坡理论分析的基础上,给出了矿用铰接式、净液压驱动车辆液压马达、液压泵的选择计算方法。在设计参数给定的情况下,可依据车辆爬坡所需的最小驱动力矩选择液压马达,通过车辆平路满载时的速度选择液压泵。最后通过液压马达可输出扭矩及液压泵排量,校核是否满足车辆爬坡的扭矩要求和爬坡速度要求。 Based on the theoretical analysis of the vehicle hill climbing, the calculation method of the hydraulic motor and the hydraulic pump of articulated and net hydraulic drive vehicles is given. Under the given design parameters, the hydraulic motor can be selected according to the minimum driving torque required for the vehicle to climb, and the hydraulic pump can be selected through the speed of the vehicle when the road is full. Finally, the hydraulic motor can output torque and displacement of the hydraulic pump to check whether the vehicle meets the requirements of climbing torque and climbing speed.
