Problems solved by technology

[0002] The inverted front shock absorber was first used in high-performance luxury racing cars and off-road vehicles. Due to its superior performance and high price, some key technologies are difficult to break through, so it has not been widely used.
The diameter of the handle tube and the total length of the casing of the traditional inverted front shock absorber currently used are relatively large. The inverted front shock absorber directly transplants the damping valve system of the rear shock absorber to the front shock absorber, which is difficult to apply to 125cc~200cc On ordinary motorcycles with small and medium displacement, if the size of the inverted front shock absorber is reduced, there is not enough space inside the handle tube to transplant all the valve train systems of the rear shock absorber into it.

Abstract

The invention discloses a compression valve of an inverted front shock absorber. An internal pipe (1) and an external pipe (2) are arranged from inside to outside in sequence in the compression valveof the inverted front shock absorber. The external pipe (2) is inserted into the internal pipe (1). The inner cavity of the internal pipe (1) is arranged as a working cavity (3). A piston rod (4) is inserted into a working cavity (12) of the internal pipe (1). A shock absorption compression valve (5) is arranged at one end of the piston rod (4). By means of the compression valve of the inverted front shock absorber, the shock absorption effect can be improved; and in addition, friction is reduced.

Description

technical field [0001] The present invention relates to an inverted front shock absorber compression valve. Background technique [0002] The inverted front shock absorber was first used in high-performance luxury racing cars and off-road vehicles. Due to its superior performance and high price, some key technologies are difficult to break through, so it has not been widely used. The diameter of the handle tube and the total length of the casing of the traditional inverted front shock absorber currently used are relatively large. The inverted front shock absorber directly transplants the damping valve system of the rear shock absorber to the front shock absorber, which is difficult to apply to 125cc~200cc On ordinary small and medium-displacement motorcycles, if the size of the inverted front shock absorber is reduced, there is not enough space inside the handle tube to transplant all the valve train systems of the rear shock absorber into it.
