Problems solved by technology

Because it is arranged outside, its protective performance is poor, and the pressure loss in the connecting pipe when the oil flows to and out of the accumulator affects the working efficiency
At the same time, the requirements for the sealing performance of the accumulator are relatively high, resulting in a high cost of the oil-gas damper produced

Embodiment 1

[0043] Such as figure 2 As shown, the piston 30 is provided with a second damping hole 503 for communicating with the upper chamber 101 of the first hydraulic cylinder chamber and the lower chamber 102 of the first hydraulic cylinder chamber.

[0044] Preferably, both the first damping hole 501 and the one-way valve 502 are one.

[0045] Preferably, there are two second damping holes 503 .

[0046] The specific working principle of the oil-gas damper of the present invention is: when the cylinder body of the first cylinder chamber 20 shrinks relative to the cylinder body of the first hydraulic cylinder chamber 10, the reduced volume of the lower chamber 102 of the first hydraulic cylinder chamber is greater than that of the first hydraulic cylinder chamber. The volume of the upper chamber 101 increases, so the oil flows from the lower chamber 102 of the first hydraulic cylinder chamber to the lower chamber 203 of the first cylinder chamber and the upper chamber 101 of the firs...

Embodiment 2

[0058] As a preferred solution in this embodiment, such as image 3 As shown, the piston 30 is provided with a second one-way valve 504 for connecting the upper chamber 101 of the first hydraulic cylinder chamber and the lower chamber 102 of the first hydraulic cylinder chamber.

[0059] Preferably, there are two second one-way valves 504, and the two second one-way valves 504 are respectively located on both sides of the first cylinder chamber 20 and on the same straight line.

[0060] In this embodiment, the oil-gas damper of the present invention saves the external accumulator of the traditional oil-gas damper by changing the internal space of the traditional piston rod, so that the structure of the oil-gas damper is more compact, which is beneficial to reduce the energy consumption of the oil-gas damper. production cost. At the same time, it also has the advantages of the following two aspects: on the one hand, the oil in the oil chamber reciprocates through the damping h...

Embodiment 3

[0062] As a preferred solution in this embodiment, such as Figure 4 As shown, an inert gas is installed in the upper chamber 101 of the first hydraulic cylinder chamber, and the inert gas is high-pressure nitrogen.

[0063] Preferably, the upper chamber 101 of the first hydraulic cylinder chamber is a sealed chamber, and the upper chamber 101 of the first hydraulic cylinder chamber is not communicated with the lower chamber 102 of the first hydraulic cylinder chamber.

[0064] In this embodiment, the oil-gas damper of the present invention saves the external accumulator of the traditional oil-gas damper by changing the internal space of the traditional piston rod, so that the structure of the oil-gas damper is more compact, which is beneficial to reduce the energy consumption of the oil-gas damper. production cost. At the same time, it also has the advantages of the following two aspects: on the one hand, the oil in the oil chamber reciprocates through the damping hole and t...

Abstract

The invention provides an oil-gas damper. The oil-gas damper comprises a first hydraulic oil cylinder chamber for filling hydraulic oil, and a first gas cylinder chamber for filling inert gas, wherein the first gas cylinder chamber is mounted on the first hydraulic oil cylinder chamber by reciprocating, and the lower end of the first gas cylinder chamber is fixedly connected to a piston of the first hydraulic oil cylinder chamber; a hydraulic control element for controlling and adjusting the hydraulic pressure of the first hydraulic oil cylinder chamber and the first gas cylinder chamber is arranged on the piston; the upper end of the first gas cylinder chamber passes through the first hydraulic oil cylinder chamber. The oil-gas damper is compact in structure, and can improve the working efficiency and reduce the manufacturing cost; the hydraulic oil in the first hydraulic oil cylinder chamber and the inert gas in the first gas cylinder chamber can be utilized to achieve the effects of oil compensating and buffering and shock absorbing.

Description

technical field [0001] The invention relates to the technical field of engineering damping, in particular to an oil-gas damper which combines hydraulic oil and inert gas to change the structural form of a traditional damper. Background technique [0002] In the late 1950s, people gradually applied oil and gas dampers to vehicles to improve vehicle comfort, handling stability and other performances. Traditional oil-air dampers are mostly used in the suspension system of vehicles. The suspension system is the key to improving vehicle ride comfort and handling stability and reducing component damage caused by dynamic loads. However, the traditional suspension based on the classic vibration isolation theory cannot meet the requirements of these aspects at the same time. The full active suspension can meet this requirement, but it cannot be put into practical engineering because of its high price. As a semi-active suspension, the oil-pneumatic suspension can not only meet the re...
