Adjustable double-cylinder oil pressure shock absorber for automobile suspension

Abstract

The invention provides an adjustable double-barrel oil pressure shock absorber for automobile suspension, which comprises an outer cylinder barrel and an inner cylinder barrel fixed in the outer cylinder barrel, the inner cylinder barrel and the outer cylinder barrel are coaxially arranged, a sliding plug is arranged in the inner cylinder barrel in a sliding way, the inner cylinder barrel is divided into an upper cavity and a lower cavity by the sliding plug, a sliding plug rod is arranged on the sliding plug, and the sliding plug rod is connected with the outer cylinder barrel. The sliding plug rod sequentially penetrates through the inner cylinder barrel and the outer cylinder barrel upwards and serves as a first connecting end, the first connecting end is provided with a main spring enabling the sliding plug to have the upward moving trend, a gap is formed between the outer wall of the inner cylinder barrel and the inner wall of the outer cylinder barrel, a flow channel is formed between the outer wall of the inner cylinder barrel and the inner wall of the outer cylinder barrel, and the flow channel is communicated with the upper cavity and the lower cavity. And a regulating valve capable of realizing bidirectional flow regulation is arranged between the bottom of the lower cavity and the flow channel. The adjustable double-cylinder oil pressure damper for automobile suspension is compact in structure, high in strength, capable of achieving different damping effects and suitable for different road conditions, driving requirements and driving feelings.

Description

technical field [0001] The invention relates to an automobile shock absorber, in particular to an adjustable double-cylinder oil pressure shock absorber for automobile suspension. Background technique [0002] The shock absorber is used to suppress the shock when the spring rebounds after shock absorption and the impact from the road surface. Widely used in automobiles, in order to accelerate the attenuation of the vibration of the frame and the body to improve the ride comfort of the car. When passing through an uneven road, although the shock-absorbing spring can filter the vibration of the road, the spring itself will have a reciprocating motion, and the shock absorber is used to suppress this spring jump. In the suspension system, the elastic element vibrates due to the impact. In order to improve the ride comfort of the car, a shock absorber is installed in parallel with the elastic element in the suspension to dampen the vibration. The working principle is that when ...

Problems solved by technology

[0003] The shock absorber in the prior art cannot adjust the damping hardness of the shock absorber according to the flatness of the ground in the driving environment of the vehicle, which makes the stability of the vehicle body poor during driving and the comfort of the user cannot be guaranteed , and it is easy to make it difficult to operate the vehicle due to the mismatch between the shock absorption hardness and the ground
