Abstract
The utility model discloses an air bag shock absorber which comprises a drum-type shock absorber component, a pressing cover, a shaft sleeve and a nut. The pressing cover is fixedly connected with one end of the drum-type shock absorber component through the nut, the shaft sleeve is fixedly connected with the other end of the drum-type shock absorber component, a limiting pipe and at least two rubber washers are arranged on the upper portion of the pressing cover, the limiting pipe is sleeved on a shock absorption shaft of the drum-type shock absorber component, and the rubber washers are sleeved on the limiting pipe. According to the air bag shock absorber, shock absorption performances are greatly improved and service life is prolonged.
Description
Technical field
The utility model relates to a kind of auto parts and components, particularly a kind of automotive airbag vibration damper.
Background technique
At present, existing automobile cab front end is connected with car body by bearing pin, then the strong point is then by metal spring or hydraulic spring grease cup damping, and its shortcoming is that metal spring is low working life, and hydraulic spring grease cup then bearing capacity is poor, damping effect is poor, therefore existing air-bag shock absorber occurred, existing air-bag shock absorber comprises that telescopic shock absorber and air bag form, but because air-bag shock absorber and automobile are to be bolted, if things go on like this do not reach the effect of damping, thereby shortened working life.
Summary of the invention
The purpose of this utility model is to provide a kind of damping performance good, the air sac damping device of long service life.
In order to achieve the above object, the technical solution of the utility model is: a kind of air-bag shock absorber, comprise telescopic shock absorber assembly, gland, axle sleeve and nut, gland is fixedly connected with an end of telescopic shock absorber assembly by nut, axle sleeve is fixedly connected with the other end of telescopic shock absorber assembly, the top of gland also has position-limiting tube and at least two rubber washers, and position-limiting tube is sleeved on the elastic axis of telescopic shock absorber assembly, and rubber washer is sleeved on the position-limiting tube.
Described rubber washer has two, and the upper and lower end of two rubber washers has packing ring.
After adopting said structure, the utility model is because the top of gland also has position-limiting tube and at least two rubber washers, position-limiting tube is sleeved on the elastic axis of telescopic shock absorber assembly, rubber washer is sleeved on the position-limiting tube, therefore passing through to install two rubber washers with the automobile shafts connecting place, install more reliably firmly, play simultaneously buffer function, damping effect is better, has greatly improved damping performance and working life.
Description of drawings
Fig. 1 is partial sectional view of the present utility model.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
As shown in Figure 1, a kind of air-bag shock absorber of the present utility model, comprise telescopic shock absorber assembly 1, gland 2, axle sleeve 3 and nut 4, gland 2 is fixedly connected with an end of telescopic shock absorber assembly 1 by nut 4, axle sleeve 3 is fixedly connected with the other end of telescopic shock absorber assembly 1, the top of gland 2 also has position-limiting tube 5 and at least two rubber washers 6, and position-limiting tube 5 is sleeved on the elastic axis 1-1 of telescopic shock absorber assembly 1, and rubber washer 6 is sleeved on the position-limiting tube 5.
Described rubber washer 6 has two, and the upper and lower end of two rubber washers 6 has packing ring 7.
As shown in Figure 2, in order better to be connected with installation fitting, described rubber washer 6 has two, and the upper and lower end of two rubber washers 6 has packing ring 7.
Air-bag shock absorber of the present utility model and automobile are installed firmly, have greatly improved damping performance and working life.
