德龙离合器助力缸（分泵）

件号：DZ93189230080
名称：离合器助力缸（离合器分泵/助力器）
Name: Clutch Booster Cylinder Assembly
归属系统：离合器操纵系统
适配机型：陕汽德龙F3000/X3000/新M3000重卡，匹配法士特系列变速箱。
功能说明：接收离合器总泵液压信号，利用压缩空气放大推力，推动离合器分离拨叉，完成离合器分离与结合，减轻驾驶员踩踏离合踏板力度，实现平顺换挡操作。
常见故障现象：助力器漏气、离合踏板沉重、离合分离不彻底、挂挡困难、踏板回位不良、漏油漏气，直接造成换挡失效。
保养提示：定期检查气路、油路接头有无渗漏；防尘套破损及时更换，避免泥水进入缸体；出现故障立即更换，禁止带病行车。
Belonging System: Clutch Control System
Applicable Models: SHACMAN Delong F3000/X3000/New M3000 heavy‑duty trucks, matched with Fast series gearboxes.
Function description: Receives hydraulic signal from clutch master cylinder, amplifies thrust by compressed air to push clutch release fork for clutch engagement and disengagement, reduces driver’s pedal force and realizes smooth gear‑shifting.
Common faults: Air/oil leakage, heavy clutch pedal, incomplete clutch disengagement, difficult gear shifting, poor pedal return, which directly leads to gear‑shift failure.
Maintenance Tip: Regularly inspect air and oil joints for leakage. Replace damaged dust‑proof boot promptly to prevent mud and water entering cylinder body. Replace immediately if faulty, do not drive with defective parts.
