专用汽车辅助工作泵驱动技术综述
Summary of Auxiliary Working Pump Driving Technology for Special Vehicles

辅助工作装置驱动液压泵主要应用于高强度作业的重型专用汽车中，齿轮泵不断地被轴向式柱塞泵所替代。本文综合介绍专用汽车的液压泵驱动及安装方式、变量液压泵的驱动特性、液压泵应用的技术特性等。
The hydraulic pump driven by the auxiliary working device is mainly used in heavy-duty special vehicles with high intensity operation, and the gear pump is constantly replaced by the axial pis-ton pump. This paper comprehensively introduces the driving and installation methods of hy-draulic pumps for special vehicles, the driving characteristics of variable displacement hydraulic pumps, and the technical characteristics of hydraulic pump applications.
