1.离合器操纵系统原理HOYUE系列汽车起重机底盘离合器操纵系统采用液压操纵、气压助力式结构,其原理如附图所示。驾驶员踩下离合器踏板1后,主缸推杆2推动离合器主缸3内的活塞向下移动,离合器主缸3活塞的油封将主缸壁上的回油孔关闭。离合器主缸3内的油液沿管路4进入离合器助力缸5,推动其液动活塞右移,将离合器助力缸5内气室的进气阀打开,压缩空
1. Clutch control system principle HOYUE series truck crane chassis clutch control system using hydraulic control, pneumatic booster structure, the principle shown in the drawings. After the driver depresses the clutch pedal 1, the master cylinder push rod 2 pushes the piston in the clutch master cylinder 3 to move downward, and the oil seal of the piston of the clutch master cylinder 3 closes the oil return hole in the master cylinder wall. The oil in the clutch master cylinder 3 enters into the clutch booster cylinder 5 along the pipeline 4 to push the hydraulic piston rightward to open the intake valve of the air chamber in the clutch booster cylinder 5 and compress the air
