Abrasion-free automobile shock absorber

Abstract

The invention discloses an abrasion-free automobile shock absorber. The abrasion-free automobile shock absorber comprises fixing rings, an upper corrugated chamber, a sound insulating sleeve, a pulling rod, a lower corrugated chamber, a guiding pipe, a shell and a cover plate; the fixing rings are arranged at the upper end and the lower end of the shell; the upper corrugated chamber is arranged on the upper half portion of the shell; the lower corrugated chamber is arranged on the lower half portion of the shell; an oil partitioning plate is arranged between the upper corrugated chamber and the lower corrugated chamber; the middle of the inner portion of the oil partitioning plate is provided with an oil passing hole; the sound insulating sleeve is arranged at the position where the upper corrugated chamber and the lower corrugated chamber overlap with each other outside the shell; a sound insulating cotton plate is arranged in the sound insulating sleeve; the pulling rod is arranged on the middle portion of the upper corrugated chamber; a fastening screw is arranged at the position of the middle of the lower portion of the pulling rod; the guiding pipe is fixedly installed on the upper surface of the shell; a valve type oil injecting hole is formed in the tail portion of the guiding pipe; an oil injecting hole screw is arranged at the bottom of the shell; and the cover plate wraps the periphery of the upper end of the pulling rod. The automobile shock absorber is simple in structure and high in practicability.

[0002] Cars are one of the most important means of transportation in modern society. With the progress of social civilization, people have higher and higher requirements for car comfort. As a special accessory to improve car comfort, the role of shock absorbers is becoming more and more important. Due to the wear of the piston and the cylinder wall of the traditional shock absorber, the original shock absorption performance will be affected when the wear exceeds the limit, especially when the oil seal between the piston pulls through and the cylinder wall is slightly worn, oil leakage will occur. , which not only affects the damping performance of the shock absorber but also pollutes the environment. Replacing the worn out shock absorber not only increases the cost of the car but also increases the maintenance workload of the car.

Moreover, the damaged shock absorber will produce noise pollution, which also seriously affects the comfort of the car.
