Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment technical characterictic of the present invention is described further:

[0025] figure 1 It is a schematic diagram of the overall structure of an embodiment of the present invention, which is a double-tube shock absorber. It is worth noting that the core of the present invention lies in the innovation of the bottom valve assembly and the pressure control valve assembly. Its structure is obviously simplified and can be By changing the valve port size of the planar throttle valve, the damping force adjustment range is further adjusted, combined with the electronic control system, the control accuracy is improved to ensure its working stability.

[0026] Such as figure 1 As shown, the shock absorber mainly includes a working cylinder 7, an intermediate cylinder 6, an oil storage cylinder 5, a bottom valve assembly 12, a pressure control valve assembly composed of a pneumatic / hydraulic piston 14 and a connectin...

Abstract

The invention relates to a pressure-controlled adjustable damping shock absorber, which includes a working cylinder, an intermediate cylinder that does not require a side connection port process, an oil storage cylinder, a guide assembly, and a piston and an internal thread piston fixing block. Piston valve assembly, bottom valve assembly, and pressure control valve assembly composed of pneumatic / hydraulic pistons and connectors; the working cylinder is installed in the inner cavity of the oil storage cylinder, the bottom end of the working cylinder matches the bottom valve assembly, and the upper end Cooperate with the guide assembly; the guide assembly cooperates with the working cylinder, the middle cylinder and the inner edge of the upper end of the oil storage cylinder respectively to form a static seal; the bottom end of the oil storage cylinder is fixedly connected with the connecting piece; the middle cylinder is located at In the cavity between the oil storage cylinder and the working cylinder, the bottom end of the middle cylinder cooperates with the bottom valve assembly to form a static seal. The shock absorber has a simple and reasonable structure, can realize automatic damping adjustment, is sensitive to the vibration of the suspension, and can be adjusted quickly.

Description

technical field [0001] The invention relates to a component used in a vehicle suspension system, in particular to a voltage-controlled adjustable damping shock absorber. Background technique [0002] Common shock absorbers for vehicle suspensions are provided with extension valves, compression valves, compensation valves and flow valves. The damping of the shock absorber depends on the elasticity of each valve group. Once the valve groups are adjusted and installed, the damping characteristics of each valve part and the overall damping performance of the shock absorber will be determined accordingly. Therefore, The ability of the suspension system to adapt to changes in road conditions has also been determined. When the road surface conditions change beyond the adaptable range of the suspension system, the damping force will be too large or too small to achieve the best damping effect, and it cannot be automatically adjusted according to the change of working conditions, so...
