Clutch master cylinder and slave cylinder are equivalent to two hydraulic cylinders. There is an oil inlet and outlet pipe on the master cylinder and only one pipe on the slave cylinder. When the clutch is depressed, the pressure of the master cylinder is transmitted to the slave cylinder. The slave cylinder works. Separate the shift fork to separate the clutch pressure plate and plate from the flywheel. At this time, the gear shift can be started. Release the clutch, the slave cylinder stops working, the clutch pressure plate and plate contact the flywheel, the power transmission continues, and the oil of the slave cylinder flows back into the oil pot. When it is difficult to shift gears and the separation is not complete, it is necessary to check the clutch master cylinder and slave cylinder for oil leakage, and solve the problems in time to reduce wear.
The main manifestation of a broken clutch slave cylinder is that it cannot be disengaged or feels particularly heavy when stepping on the clutch. In particular, I find it difficult to shift gears and incomplete separation. There will even be oil leakage from the cylinder.
? working principle of clutch slave cylinder:
When the clutch pedal is pressed, the hydraulic oil in the clutch master cylinder is transmitted to the clutch slave cylinder through the high-pressure pipeline, and the pressure of the hydraulic oil is applied to the plunger cup in the clutch slave cylinder, so as to push the plunger rod forward, and the plunger rod pushes the release lever forward, so as to push the release lever under the pressure of the release shaft, Realize the power separation between the clutch cut-off engine and the transmission device. When the clutch pedal is lifted, the power is combined.
? main purpose of clutch slave cylinder:
The clutch is installed between the engine and the transmission. The clutch is often used in the whole process from starting to driving. Its function is to gradually connect the engine and transmission, so as to ensure the smooth start of the vehicle; Temporarily cut off the connection between the engine and the transmission to facilitate gear shifting and reduce the impact during gear shifting; When the vehicle is under emergency braking, it can play a separation role, prevent the transmission system such as transmission from overload and play a certain protective role.
? repair method for oil leakage of clutch slave cylinder:
It is recommended to replace the assembly. The oil leakage of the clutch slave cylinder is caused by the wear of the piston, leather ring and cup in the clutch slave cylinder, which can not seal the clutch oil, because now the clutch slave cylinder can't produce parts, and it's not easy to repair the leather ring, so we have to replace the assembly.
