Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain that this is practical
It is novel, it is not used to limit the utility model.
The application principle of the utility model is explained in detail with reference to the accompanying drawing.
The centering type air spring vibration damper assembly of lateral force provided by the present invention as shown in Figs. 1-3, including on to
Under the upper cover 3, air bag 6, lower piston 9 and the piston fixing seat 10 that set gradually, the lower piston 9 is solid by piston fixing seat 10
It is scheduled on the inside of air bag 6, along the direction of air spring active force, the center line A300 of the upper cover 3 and the lower work
The center line B900 of plug 9 is not overlapped.
It further include the absorber rod 5 for connecting upper cover 3 and lower piston 9, the upper end of the absorber rod 5 passes through rubber bushing
4 and nut 1 be fixed on the center of upper cover 3, the center of lower piston 9 is inserted into lower end.The bottom end of the absorber rod 5 also
It is connected to the shock absorber cylinder 11 stretched out outside piston fixing seat 10.
As seen from Figure 3, absorber rod 5 is added, the balance of damper glances off, so that in the upper cover 3
Heart line A300 is glanced off with the center line B900 of the lower piston 9 by original parallel state, intersects at spatially certain
A bit.So that producing contact area not etc. between the left and right sides and air bag 6 of lower piston 9.In the effect of lateral force
Under, the area that the air bag 6 acts on 9 upper end of lower piston increases.Since 6 internal pressure of air bag is identical, the lower piston 9 with
The big side stress of the surface area that air bag 6 contacts can be greater than the side small with 6 contact surface area of air bag, cause lower piston 9 and rubber
The certain angle of each self-deflection of glue bushing 4, causes shock absorber cylinder 11 and absorber rod 5 to generate certain pre-pressing force, produced
Pre-pressing force generate component in the position close to damper approximation central axes, and then provide certain lateral force.
As shown in Figure 1, the rotation top glue 12 revolves the invention also includes the rotation top glue 12 for being set to 3 top surface of upper cover
Turn top glue using flexible rubber material, damage of the lateral force to spring damper is offset by elastic force.
Corresponding, the top of upper cover 3 or rotation top glue 12 is arranged in the sealing cover in the present invention, corresponds to installation rubber
The center of upper cover 3 is arranged in the position of the accommodating hole of bushing 4, the accommodating hole for installing rubber bushing 4.
In order to improve the service life of damper, the present invention is also protected by increasing shield 7 in the outer layer of air bag 6
Shield prevents air bag 6 because of the damage caused by external abrasion.The lower end of the shield 7 is connected to the dirt-proof boot 8 of retractility,
The bottom end of the dirt-proof boot 8 is connected with piston fixing seat 10, the demand for cooperating shock absorber cylinder 11 to move up and down.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
