Background technique
Air spring damper in the prior art is mainly used for providing enough lateral force support vehicle bodies and protection damping
The oil sealing of device is by excessive lateral force, in use, if enough lateral forces cannot be provided, when steering will cause side tilt angle
Greatly, roll velocity is fast, influences driving experience sense and safety, while damper being made to bear excessive lateral force, causes damping
The oil sealing premature breakdown of device, in turn results in the oil leak of damper, causes the disabling damage of damper.And air spring is horizontally
It cannot be capable of providing the characteristic of enough power as conventional steel spring, need to provide enough by rationally designing structure
Lateral support.Especially McPherson suspension, lateral force needed for the lateral force needed is greater than other suspensions.
Some products (especially market product after automobile) of existing air spring shock absorber structure do not account for air bullet
The problem of lateral force of spring, causes damper to bear excessive lateral force, oil seal for shock damper is caused to damage, and leads to the leakage of damper
Oil failure.Cause the reliability decrease of product.The level angle and air spring lower piston of position are withheld by changing upper cover
Eccentric angle provides lateral force, but this mode is first to the air bag of air spring by certain requirement, because of air bag one
It directly is exposed to outside, the not protection of guard shield is found the work that stone is rolled into lower piston and air bag in use
Make position, long-time precocity air bag damages gas leak phenomenon.Secondly this change upper cover withholds the level angle and air bullet of position
The eccentric angle of spring lower piston needs enough spaces that air spring is allowed to generate bending deformation, not all vehicle to provide lateral force
Type all uses this mode by enough spaces.
Summary of the invention
In view of the above-mentioned problems, the present invention proposes a kind of centering type air spring vibration damper assembly for being capable of providing lateral force.

Air bag, lower piston and piston fixing seat, the lower piston are fixed on the inside of air bag by piston fixing seat, along air bullet
The direction of spring active force, the center line A of the upper cover are not overlapped with the center line B of the lower piston.
It as a further improvement of the present invention, further include the absorber rod for connecting upper cover and lower piston, in absorber rod
Under effect, the center line A of the upper cover intersects with the center line B of the lower piston.
As a further improvement of the present invention, the contact area of the left and right sides of the lower piston and air bag differs,
Under the action of lateral force, the area of the air bag effect lower piston upper end increases.
It as a further improvement of the present invention, further include the rotation top glue for being set to upper cover top surface.
As a further improvement of the present invention, the upper end of the absorber rod is fixed on by rubber bushing and nut
The center of lower piston is inserted into the center of lid, lower end.
As a further improvement of the present invention, the accommodating hole of installation rubber bushing is provided at the center of the upper cover,
Top pressure closure is provided in the position that the top of upper cover or rotation top glue corresponds to accommodating hole.
As a further improvement of the present invention, under the action of lateral force, the lower piston or the rubber bushing
It is deflected to the action direction of lateral force.
It as a further improvement of the present invention, further include the shield and concertina type being vertically connected in the outermost of damper
Dirt-proof boot, the shield are coated on the outside of air bag, the bottom end of dirt-proof boot be connected with piston fixing seat.
Beneficial effects of the present invention: by being eccentric type structure by air spring shock absorber design in the present invention, so as to
There is provided enough lateral forces enough to meet the needs of vibration damper assembly is to lateral force.Space layout of the invention simultaneously is compact, peace
Quan Xing, reliability further increase.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
Application principle of the invention 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 above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
