Abstract

The utility model provides a shock absorber which comprises a rubber air spring assembly and a vibration damper, wherein the rubber air spring assembly consists of an upper cover, an air inlet, an air spring rubber component and a lower seat; the upper cover is sleeved on the piston rod of the vibration damper; the air inlet is formed on the upper cover; the upper end of the air spring rubber component and the upper cover are combined together in a self-sealing manner under the pressure of the stopper of the rubber component; the lower end of the air spring rubber component and the lower seat are combined together in a self-sealing manner under the pressure of the stopper of the rubber component; and the lower seat is sleeved on the barrel body of the vibration damper. The shock absorber combines the rubber air spring assembly and the vibration damper as a whole; can reduce the installation space, simplify the fixation condition and improve the heat-dissipating effect of the vibration damper; takes the bearing and buffing functions as well as the vibration-damping function; and is applied to the suspension and mounting system of vehicles, particularly high-speed heavy-duty vehicles.

Description

Shock absorber
Technical field:
The utility model relates to rubber air spring assembly and vibration damper field, and particularly a kind of rubber air spring assembly and damper combination are the shock absorber of one.
Background technique:
In the prior art, being applied to rubber air spring (or leaf spring) in the vehicle suspension system and vibration damper has become two requisite parts and has used separately, uses as vehicle component, and the demand of its installing space and rigid condition is bigger.Wherein, rubber air spring uses as single part has vibration damping and buffering effect, and its bearing capacity is poor, and the scope of single application is more and more littler; Though and vibration damper has vibration damping, carrying and buffering effect simultaneously, but the vibration damping and vibration isolation requirement of the low-frequency vibration that dither that is produced at high speed machine equipment or heavy load, low-speed machinery equipment are produced, especially the free vibration requirement that still can not reduce rapidly decay time, still there is bigger shortcoming, its radiating effect is unsatisfactory in the high speed operation, and also can reduce greatly working life.
The model utility content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of installing space of saving is provided, and is simplified to fix condition, improves radiating effect, and is applied widely, and collection vibration damping, carrying, buffering and absorption percussion are the shock absorber of one.
In order to realize the foregoing invention purpose, the utility model has adopted following technological scheme:
A kind of shock absorber, comprise rubber air spring assembly and vibration damper, described rubber air spring assembly by loam cake, air inlet chew, air spring rubber spare and following form, described loam cake is socketed on the shock absorber piston rod, described air inlet is chewed to be installed in and is covered on described, described air spring rubber spare upper end is combined by the pressure selfsealings of rubber parts seam with described loam cake, described air spring rubber spare lower end and described following the pressure selfsealings by the rubber parts seam are combined, and described cover for seat down is connected on the vibration damper cylindrical shell.
The inner and outer rings body that described loam cake comprises a plane plate and is located at this plane plate lower end is equipped with buffer stopper between the described inner and outer rings body, is provided with seal ring between described interior annular solid and the shock absorber piston rod; The seam of described air spring rubber spare cooperates with the outer surface of described outer shroud body.
A described following top is provided with cushion pad, and described cushion pad is socketed on the shock absorber piston rod, is provided with seal ring between a described following lower end and the vibration damper cylindrical shell.
A described following bottom is equipped with a supporting plate, and described supporting plate is fixed on the vibration damper cylindrical shell.
Described vibration damper upper/lower terminal all is equipped with a jointing.
The utility model has been owing to adopted above technological scheme, thereby has following advantage with respect to prior art:
First, this shock absorber is rubber air spring assembly and damper combination one body technique, the installing space in vehicle has been saved in both combinations, simplified rigid condition, make its function that has rubber air spring and vibration damper simultaneously and advantage, possess carrying, buffering and damping effect, and play the effect of impacting that absorbs, be suitable for vehicle hanging and suspension system and use, particularly the high-speed overload vehicle.
The second, the buffer stopper that the utility model is provided with in the loam cake lower end and the following cushion pad that the top is provided with can effectively prevent down the direct collision and be damaged the working life of increase rubber air spring assembly when the absorption percussion of seat and loam cake.
The 3rd, be equipped with seal ring between loam cake, following and the vibration damper, the rubber air spring assembly is connected with vibration damper has good air-tightness, guaranteed that the rubber air spring assembly utilizes air pressure to absorb the effect of impacting.
The 4th, the supporting plate that following seat bottom is provided with can prevent down that seat produces downward relatively displacement, has fixed the position between time seat and the vibration damper.
Description of drawings:
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model sectional structure schematic representation.
Embodiment:
As shown in Figure 1, a kind of shock absorber that provides according to the utility model, comprise rubber air spring assembly 1 and vibration damper 2, rubber air spring assembly 1 is by loam cake 11, air inlet chews 12, air spring rubber spare 13 and following 14 composition, loam cake 11 is socketed on the shock absorber piston rod 21, described air inlet is chewed 12 and is installed on the loam cake 11, air spring rubber spare 13 upper ends and loam cake 11 are combined by the pressure selfsealings of rubber parts seam, air spring rubber spare 13 lower ends are combined with following the 14 pressure selfsealings by the rubber parts seam, and following seat 14 is socketed on the vibration damper cylindrical shell 22.
As mentioned above, the inner and outer rings body 112,113 that loam cake 11 comprises a plane plate 111 and is located at these plane plate 111 lower ends, between the inner and outer rings body 112,113 buffer stopper 3 is installed, is provided with seal ring 5 between interior annular solid 112 and the shock absorber piston rod 21; The seam of air spring rubber spare 13 cooperates with the outer surface of outer shroud body 113.Following seat 14 tops are provided with cushion pad 4, and cushion pad 4 is socketed on the shock absorber piston rod 21, are provided with seal ring 8 between following seat 14 lower ends and the vibration damper cylindrical shell 22.The setting of seal ring 5 and seal ring 8 can make rubber air spring assembly 1 and being connected of vibration damper 2 have good air-tightness, has guaranteed that rubber air spring assembly 1 utilizes air pressure to absorb the effect of impacting.The setting of buffer stopper 3 and cushion pad 4 also can effectively prevent down the direct collision and being damaged when absorbing percussion of seat 13 and loam cake 11, increases the rubber air spring assembly purpose in 1 working life thereby reach.
