我公司设计生产的YZ14G振动压路机上的转向泵与1002履带式拖拉机的转向泵连接装置相同，其结构如图1所示。工作时拨动接合杠杆3，使传动套9带动联轴节10滑动，实现与发动机联轴节1的接合与分离。该结构在用于1002履带式拖拉机时，主要用于控制铲刀和后悬挂装置的升降，当拖拉机
The steering pump on the YZ14G Vibratory Roller designed and manufactured by our company is the same as the steering pump connecting device of the 1002 crawler tractor. Its structure is shown in Fig.1. Work toggle joint lever 3, so that the drive sleeve 9 to drive the coupling 10 slide to achieve the coupling and the engine coupling 1 and separation. The structure is mainly used to control the lift and drop of the blade and the rear suspension when used on a 1002 crawler tractor. When the tractor
