Description

Technical Field

[0001] The utility model relates to a shock absorber, in particular to a novel air bag shock absorber, belonging to the technical field of shock absorbers. Background Art

[0002] In the suspension system, elastic elements are impacted and vibrate. To improve the riding smoothness of motorcycles, shock absorbers are installed in parallel with the elastic elements in the suspension. To attenuate vibrations, most shock absorbers used in motorcycle suspension systems are hydraulic shock absorbers, which convert the vibration energy of the motorcycle into oil heat energy, which is then absorbed by the shock absorbers and dissipated into the atmosphere. The airbag shock absorber is based on this type of shock absorber and uses an airbag to discharge or introduce gas to alleviate the change in the volume of the hydraulic chamber caused by the movement of the inner rod.

[0003] A shock absorber with an externally mounted airbag and adjustable damping is disclosed in the Chinese patent application publication specification CN213176623U, in which an airbag pipe, a first airbag and a second airbag are arranged to solve the problem that the traditional shock absorber airbag is inside and cannot well control the output of nitrogen, and thus cannot well adjust the damping. The utility model has an external airbag, and nitrogen is transported to the inside of the shock absorber through the airbag pipe. The control valve on the airbag pipe can control the output of nitrogen in the first airbag and the second airbag, thereby achieving the effect of adjusting the damping.

[0004] Although the above patent can control the nitrogen output in the first airbag and the second airbag by delivering nitrogen to the inside of the shock absorber, thereby achieving the effect of adjusting the damping, the first airbag and the second airbag lack a cooling device. The airbag shock absorber transfers the damper with damping effect to the airbag position. Therefore, the airbag will generate heat during the shock absorption process. If it is not cooled, the temperature of the airbag will rise rapidly when facing bumpy roads, affecting its normal use. At the same time, in the above patent, the first spring and the second spring are directly exposed to the outside. When the vehicle travels on muddy roads for a long time, mud and sand will splash to the first slide bar and the second slide bar, affecting the normal use of the first damping cylinder and the second damping cylinder. Utility Model Content

[0005] The utility model provides a novel airbag shock absorber to solve the problem in the prior art that the airbag temperature rises and affects the normal use of the airbag shock absorber when the airbag shock absorber is used for a long time, and solves the problem that the splashing of mud and sand during use of the airbag shock absorber affects the normal use of the damper.

[0006] The utility model is implemented through the following technical scheme: a novel airbag shock absorber, including a damping device for providing shock-absorbing and damping effects, the damping device including a damping cylinder and a sliding rod sealingly slidably connected to the top of the damping cylinder, an airbag device is arranged on the left side of the damping device, the bottom end of the airbag device is connected to the damping cylinder through a pipeline, a protective device is arranged on the outer side of the damping device, a connecting plate is fixed to the top end of the sliding rod, and connecting rings are installed on the upper surface of the connecting plate and the bottom surface of the damping cylinder.

[0007] The damping device also includes a partition plate, which is located inside the damping cylinder and is fixed to the slide rod. When the connecting ring is subjected to force, the slide rod is squeezed, and the partition plate can be driven to move up and down through the slide rod.

[0008] Two circumferentially arranged oil valves are installed on the upper surface of the partition plate. The size of the oil valve is smaller than the distance from the outer side of the slide rod to the edge of the partition plate. The oil valve can help mitigate the impact caused by vibration during the lifting and lowering of the partition plate through the friction generated by the hydraulic oil flowing through the valve body.

[0009] The airbag device includes an airbag pipe, the inner wall of the airbag pipe is slidably connected to a baffle, the baffle is slidably and sealingly connected to the inner wall of the airbag pipe, the airbag pipe is divided into an air chamber and an oil chamber by the baffle, the oil chamber is connected to the damping cylinder, the hydraulic oil inside the damping cylinder can enter the oil chamber and thus extend the damping stroke of the damping cylinder.

[0010] An inflation valve is installed at the top of the airbag pipe, and the inflation valve is connected to the air chamber. High-pressure nitrogen can be delivered to the interior of the air chamber through the inflation valve to adjust the position of the baffle, thereby completing the adjustment of the damping stroke.

[0011] The protective device includes a support ring installed on the outer surface of the damping cylinder, a bellows and two protective sleeves are installed between the support ring and the connecting plate, an air intake valve is provided on the outer surface of the upper protective sleeve, and an exhaust valve is provided on the outer surface of the lower protective sleeve. The exhaust valve is aimed at the airbag pipe, and the gas discharged through the exhaust valve is blown onto the outer surface of the airbag pipe to cool the airbag pipe.

[0012] A return spring is installed between the connecting plate and the supporting ring. A plurality of air inlets are provided on the outer surface of the protective sleeve. The size of the air inlets is smaller than the size of the air inlet valve and the exhaust valve.

[0013] The utility model provides a novel airbag shock absorber, which has the following beneficial effects:

[0014] 1. The novel airbag shock absorber is provided with a bellows and a protective cover, so that when the bellows is vibrated and stretched, gas enters the inside of the bellows from the air inlet valve, and when it is vibrated and compressed, gas is discharged from the exhaust valve of the protective cover. As the protective cover descends, the exhaust valve descends together. During the descent of the exhaust valve, the airflow ejected blows to the outer surface of the airbag pipe, which assists in its rapid cooling, thus solving the problem in the prior art that the airbag temperature rises and affects its normal use when the airbag shock absorber is used for a long time.

[0015] 2. The new airbag shock absorber is provided with a protective device so that in daily use, the bellows and the protective cover can block mud and sand outside, reducing the impact of mud and sand splashing on the damper when driving on a dirt road, thus solving the problem that the splash of mud and sand will affect the normal use of the damper when the airbag shock absorber is in use.
