High-pressure absorber with double cylinders provided with floating piston assembly

Abstract

The invention provides a high-pressure absorber with double cylinders provided with a floating piston assembly. The high-pressure absorber comprises an inner working cylinder, a piston assembly arranged in the inner working cylinder, damping oil, inert gas and a piston rod on a piston, wherein the upper part of the inner working cylinder is provided with a guider; the upper end of the guider is provided with a sealing dustproof cover and a sealing ring; an outer working cylinder is arranged outside the inner working cylinder; the floating piston assembly is arranged in a cavity of the outer working cylinder; a compression valve assembly is arranged in a bottom area, which is matched with inner walls of the outer working cylinder, of the inner working cylinder; an oil through valve is arranged inside the compression valve assembly; the valve is opened through damping force so that an oil way between the inner working cylinder and the outer working cylinder is unblocked; the inert gas is filled in an upper area, in which the floating piston assembly is arranged, of the outer working cylinder; and the damping oil is filled in other areas between the inner working cylinder and the outer working cylinder. The floating piston assembly is arranged in the cavity of the outer working cylinder, and an oil storage area of the damping oil is enlarged, so that the travel of the piston is maximized; connecting rods of various specifications can be applied to the absorber; and the absorber is wide in application and is an ideal absorber.

Description

[0001] technical field [0002] The invention relates to a vehicle shock absorber which improves the stability of the vehicle during running, in particular to a high-pressure shock absorber with a double cylinder and a floating piston assembly. [0003] Background technique [0004] Shock absorber (Absorber), the shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. Shock absorber is too soft, automobile body can hop up and down, shock absorber can bring too great resistance too forcedly, cloggy bedspring works normally. In the process of refitting the suspension system, hard shock absorbers should be matched with hard springs, and the hardness of the springs is closely rela...

Problems solved by technology

[0009] When the vehicle bumps frequently and has a large amplitude, the circulation of shock absorbing oil in the cylinder is lagging behind, and a vacuum area is likely to appear in the cylinder, and the piston can no longer work to the original lower position, making the compression damping increase to an unacceptable value

Moreover, it is prone to abnormal noise from noise and vibration, which seriously affects the shock absorption effect

Chinese patent, the patent number is 200620141855.7, the patented technology named "Cylinder Hydraulic Shock Absorber with Floating Piston", a floating piston device is installed at the bottom of the cylinder, which basically solves the above problems, but this technology still has shortcomings, If the volume filled with high-pressure gas is too small, it cannot be used for shock absorbers with large connecting rods

When a vehicle using this type of shock absorber encounters a continuous bumpy road section, the cushioning performance of the shock absorber is greatly tested. Although the shock absorption performance will be greatly improved compared with the previous one, the shock absorption effect is relatively hard, which makes driving Indoor drivers and passengers feel uncomfortable, and the internal cushioning performance of the shock absorber needs to be improved. For large strokes, there is still a lot of room for improvement for the special shock absorber for large connecting rods.
