Improved automobile clutch booster

Abstract

The invention relates to an improved automobile clutch booster, namely, the cross-sectional area of a piston rod becomes small, so that the required effective area of a large piston when the large piston does work is increased, the resistance is also reduced, and the power of the clutch booster can be increased by 10% on the basis of the original product. The phenomena of sticking, powerless property and non-thorough separation of the clutch booster during the use can be avoided. In addition, wear rings containing lubricating grease are increased at the parts which are adjacent to leather cups in the clutch booster, so that all the leather cups can regularly work under a lubricational state, and the service life of the clutch booster is greatly prolonged. Simultaneously, the mounting position and the way of a valve seat are also changed, the operation is easy, and potential risks are also eliminated.

Description

technical field [0001] The invention belongs to the field of auto parts and relates to an improved auto clutch booster. Background technique [0002] At present, the clutch boosters on automobiles at home and abroad often have problems such as card issuance, air leakage and incomplete separation during use, and their service life is not long. Correction of its reasons, mainly caused by the following aspects: [0003] 1. In each part of the clutch booster adjacent to the cup, the content of grease is less. In particular, the large piston cup in the cylinder, which is responsible for the main work, has less lubricating grease around it, so that it often works in a dry grinding state, which will cause corrosion on the inner wall of the cylinder and scratches on the large cup. . This reduces the service life of the clutch booster. [0004] 2. In the cylinder barrel, the piston rod connected to the radial center of the large piston transmits torque and guides the large piston...

AI Technical Summary

Problems solved by technology

Therefore, the cross-sectional area of ​​the piston rod is too large, which affects the thrust of the large piston to a certain extent, and makes the clutch booster prone to pinching, powerlessness and incomplete separation during use.

[0005] 3. In the existing product structure, the valve seat of the clutch booster needs to be installed in the deep blind hole of the oil-air cavity, which is very difficult to operate, which not only affects the assembly speed, but also easily leaves hidden dangers and forms a point of failure
