Problems solved by technology

However, due to the special structure of the single-sided piston, the damping force value is only generated when it is stretched, and the damping force value is generated by the compression valve when it is compressed. Big
When some models use this kind of valve system, there will even be abnormal noises, which will affect the actual use and cause customer complaints

Embodiment Construction

[0014] The double-sided piston valve shock absorber includes an oil storage cylinder 1, a working cylinder 2 arranged in the oil storage cylinder 1, a piston rod 3 is arranged on the working cylinder 2, and a double-sided piston 4 is arranged on the piston rod 3.

[0015] The double-sided piston 4 is provided with three flow holes 5, and the cross-sectional shape of the flow holes 5 is an ellipse hole.

[0016] The flow hole 5 is in the form of an abrupt change in the axial direction.

[0017] The flow hole 5 adopts a structural form in which small elliptical holes, large elliptical holes, and small elliptical holes alternate in sequence along the axial position.

[0018] The flow hole 5 is in the form of a circular arc structure with two large ends and a small middle along the axial direction.

[0019] The circulation holes on the double-sided piston valve of the present invention are initially designed as three round holes with a diameter of 2.0. During actual debugging, es...

Abstract

The invention relates to a double-faced piston valve damper which comprises an oil storage cylinder (1), and a working cylinder (2) arranged inside the oil storage cylinder (1), a piston rod (3) is arranged on the working cylinder (2), and a double-faced piston is arranged on the piston rod (3). By designing a valve system inside a product again, the adjustable range of a damping force value of the valve system is wider, the damping force value is more stable, response of the valve system is rapider, and the customer satisfaction is remarkably improved.

Description

technical field [0001] The invention relates to a double-sided piston valve shock absorber, which belongs to the technical field of shock absorbers. Background technique [0002] Hydraulic shock absorbers are deeply loved by customers because of their superior shock absorption performance and high cost performance. The piston valve is an essential key component of the hydraulic shock absorber. Conventional hydraulic shock absorbers generally use single-sided piston valves. However, due to the special structure of the single-sided piston, the damping force value is only generated when it is stretched, and the damping force value is generated by the compression valve when it is compressed. big. When some models use this kind of valve system, there will even be abnormal noises, which affect the actual use and cause customer complaints. Contents of the invention [0003] The purpose of the present invention is to provide a double-sided piston valve shock absorber with reas...
