Abstract

The invention provides a bottom valve of an oil pressure shock absorber. It includes a bottom valve body, a valve plate, a spring, a valve plate cover, a bottom valve core shaft and a bottom valve valve system; the bottom valve body includes a first flow hole, a second flow hole and a bottom valve core shaft installation hole; A filtering device is provided between the end face of the first end of the bottom valve body and the end face of the first end of the valve block; the first end of the valve block is provided with a passage corresponding to the first flow hole. hole; the valve plate is set on the first end of the valve plate cover and covers the second flow hole of the bottom valve body, and a spring is arranged between the valve plate and the second end of the valve plate cover; The bottom valve system is installed on the second end of the bottom valve body and is attached to the end of the first flow hole; the valve cover is sequentially connected with the bottom valve body and the bottom valve system through the bottom valve core shaft . The invention can realize the one-way flow of the oil at the bottom valve and filter the particle impurities in the oil, preventing the impurities from entering the bottom valve system and affecting the damping characteristics of the oil pressure shock absorber.

Description

technical field [0001] The invention relates to the technical field of oil pressure damping, in particular to a bottom valve of an oil pressure damper. Background technique [0002] Oil shock absorber is an important part of various vehicles, and its damping characteristics directly affect the safety, stability and comfort of vehicle operation. The bottom valve of oil pressure shock absorber is an important structure to ensure the damping characteristics of oil pressure shock absorber. The stability and reliability of its performance directly affect the reliability of shock absorber. [0003] During the use of the hydraulic shock absorber, on the one hand, the particles in the working chamber of the hydraulic shock absorber enter the bottom valve valve system of the bottom valve with the oil, which will cause leakage of the bottom valve and affect the damping of the hydraulic shock absorber. characteristics; on the other hand, when the oil flow holes of the various componen...
