Problems solved by technology

[0012] In order to ensure a compact structure, the damping valve is usually installed on the piston. Once the assembly is completed, it is found through the test that the damping valve cannot work normally, or when it is necessary to adjust the valve group to change the damping force to meet the loading requirements, it must be disassembled and replaced. Parts will be very difficult, and the disassembled oil and gas spring seals often need to be replaced as a whole, resulting in unnecessary waste; this kind of oil and gas spring can only be applied to the needs of a certain model, and it is difficult to change the structure of the valve group on the original basis To meet the requirements of other vehicles, the versatility is not good

Embodiment Construction

[0037] The following is a detailed description of the oil-pneumatic spring buffer device in conjunction with the accompanying drawings:

[0038] The hollow piston rod 1 is set in the cylinder barrel 2, the upper end of the piston rod 1 is equipped with a combined piston 13, and is connected together by threads, and the lower end is equipped with a lower joint assembly 8 to form a closed end, so as to pass through the connecting piece and The connecting arms of the axle are connected. The inner chamber of the piston rod is equipped with a floating piston 12, which divides the inner chamber of the piston rod into two chambers. The upper chamber is filled with oil, called the piston rod oil chamber A, and the lower chamber is filled with corresponding high-pressure inert oil chamber according to the static load of the vehicle. Gas, called piston rod cavity B. The upper end of the cylinder 2 is equipped with an upper joint assembly 15, which forms a closed end so as to be connect...

Abstract

The present invention is a combination of oil and gas piston spring, including Piston Rings , Cover, bearing cap, ring-group throttle and adjustment ring gasket. Bearing cap with the thread through the rod attached to the throttle-group and the adjustment for gasket sets in the back end of the Detroit Piston Ring Cover and connected through the thread. The invention of on the basis the original oil and gas in the spring can change resistance in order to achieve different requirements of the traffic movement. In the absence of the destruction of the cylinder seal, this enables oil and gas spring by the substantial increase in common. Attenuation of the invention can be used body vibration, enhancing vehicle safety, ride comfort and off-road speed.

Description

technical field [0001] The invention relates to a combined piston for oil and gas springs. It belongs to the field of hydraulic machinery and motor vehicle applications. Background technique [0002] Suspension is the general term for all force transmission connection devices between the frame (or load-bearing body) and the axle (or wheel). In a popular sense, the suspension system is composed of elastic elements, damping elements and guiding devices. Of course, in terms of specific structural realization, the above-mentioned components may not all appear in an independent form. [0003] In the prior art, except oil-gas springs, the types of elastic elements used in vehicle suspension systems mainly include: leaf springs, coil springs, torsion bar springs, rubber springs and gas springs. Leaf springs, helical springs, and torsion bar springs have relatively small energy storage per unit mass, so they can absorb vibration energy to a limited extent while the vehicle is run...
