Problems solved by technology

However, in the prior art, if you want to change the hardness of the shock absorber, you need to inflate or deflate the airbag device. Only by changing the air pressure state in the airbag device can you change the hardness of the shock absorber. Convenient, if you want to change from low air pressure to high air pressure, you need to use inflatable parts together, if you don’t carry inflatable parts, it will make it difficult to achieve the effect of adjusting the hardness
[0003] The application number is CN201921336006.0, which discloses a new type of shock absorber, which changes the resistance to damping oil in the oil channel by adjusting the screw. This adjustment method is easy to leak damping oil
Under long-term leakage, it is easy to cause oil pressure changes, resulting in poor use effect

Embodiment A

[0032] Embodiment A, the thread on the shock absorber body 1 is an external thread, and the thread on the airbag device 2 is an internal thread; The threaded first sealing ring 41, the first sealing layer 42 arranged on the surface of the first sealing ring 41 opposite to the shock absorber body; when the airbag device 2 is screwed in place with the shock absorber body 1, the first sealing ring 41 offsets against the shock absorber body 1.

[0033] Under the above setting, it means that the airbag device 2 is threadedly connected with the shock absorber body 1 in such a way that the airbag device 2 is sleeved outside the shock absorber body 1, and this connection method can be used to maintain the same length of the airbag device 2 It has a larger oil storage space. At the same time, the first sealing ring 41 can be arranged in the air bag device 2, and the position of the first sealing ring 41 can be adjusted very conveniently after the air bag device 2 is taken off. The ai...

Embodiment B

[0034] Embodiment B, the thread on the shock absorber body 1 is an internal thread, and the thread on the airbag device 2 is an external thread; The second sealing ring of the matching thread, the second sealing layer arranged on the surface of the second sealing ring opposite to the air bag device 2; when the air bag device 2 and the shock absorber body 1 are screwed in place, the second sealing ring and the air bag Device 2 offsets.

[0035] This embodiment differs from embodiment A mainly in that the internal and external threads are matched in a different manner. At this time, the second sealing ring is exposed to the outside. Compared with embodiment A, it is easy to cause the aging of the second sealing layer and affect the sealing effect. At the same time, it is easy to cause the capacity to be small, and the length of the airbag device 2 needs to be increased to increase the capacity, which will cause installation inconvenience.

[0036] Further improvement is made fo...

Abstract

The invention discloses a damping-adjustable air bag shock absorber which comprises a shock absorber body and an air bag device connected with the shock absorber, and an adjusting assembly used for adjusting damping is arranged on the air bag device. The adjusting assembly comprises a thread arranged on the shock absorber body, a sealing piece arranged on the air bag device and a thread arranged on the air bag device and matched with the shock absorber body. The air bag device is connected with the shock absorber body through threads, and the air bag device and the shock absorber body are sealed through a sealing piece. The thread stroke on the air bag device is matched with the thread stroke on the shock absorber body, and damping in the air bag device is adjusted through the threaded connection depth of the air bag device and the shock absorber body. According to the damping-adjustable air bag shock absorber, the damping adjusting effect can be provided under the condition of avoiding oil leakage.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to an airbag shock absorber with adjustable damping. Background technique [0002] Cars and motorcycles often have impacts due to ground problems during driving, which can easily cause drivers to accidentally touch various operating components, thereby causing safety problems. Shock absorbers can solve the above problems well, so they are widely used in automobiles and motorcycles. The existing airbag shock absorber adopts a combination of a shock absorber body and an airbag device, and the airbag device supplies gas to the shock absorber body to change the hardness of the shock absorber, thereby adapting to various working conditions. However, in the prior art, if you want to change the hardness of the shock absorber, you need to inflate or deflate the airbag device. Only by changing the air pressure state in the airbag device can you change the hardness of the shock absorber. Conv...
