Description
Technical field
The invention belongs to damper fields, and in particular to a kind of to provide the air spring damping of lateral force based on lever mechanism
Device assembly.
Background technique
Prior art air spring vibration damper assembly wants that enough lateral force support vehicle bodies can be provided and protects damper
Oil sealing is by excessive lateral force, if enough lateral forces cannot be provided, it is big that when steering will cause side tilt angle, angle of heel speed
Degree is fast, influences the comfortableness and security driven, while damper being made to bear excessive lateral force, causes the oil sealing mistake of damper
Early damage, in turn results in the oil leak of damper, causes the disabling damage of damper.And air spring horizontally cannot be as tradition
Steel spring is capable of providing the characteristic of enough power like that, needs that enough lateral branch can be provided by rationally designing structure
Support.
Suspension not only will bear lateral force in turning, when bodywork height changes, at the top of damper and suspension
Angle can also change, can also generate lateral force.
For McPherson strut, lateral force needed for the lateral force needed is greater than other suspensions.
Some products (especially market product after automobile) of existing air spring vibration damper assembly structure do not account for sky
The problem of lateral force of gas spring, causes damper to bear excessive lateral force, oil seal for shock damper is caused to damage, leads to damper
Oil leak failure.Cause the reliability decrease of product.
There is the eccentric angle by changing level angle and air spring lower piston that upper cover withholds position to provide at present
Lateral force, but this mode, because air bag is constantly exposed to outside, does not have first to the air bag of air spring by certain requirement
There is the protection of guard shield, is found the operating position that stone is rolled into lower piston and air bag in use, it is early for a long time
Gas leak phenomenon is damaged at air bag.Secondly this change upper cover withholds the eccentric angle of the level angle and air spring lower piston of position
Degree needs enough spaces that air spring is allowed to generate bending deformation to provide lateral force, and not all vehicle is all by enough spaces
Using this mode.
There are also designs to provide lateral force by eccentric upper cover, but such structure is also required to occupy biggish upper cover space,
And the lower piston of air spring and the fixed position of the air bag of upper cover are eccentric, and if eccentric excessive, insufficient space, the not no gas of air bag
When be likely to cause the fixed position of air spring upper cover air bag and lower piston air bag collides and causes the damage of air bag, therefore, adopt
There are enough spaces in vertical direction with this structure.
Summary of the invention

Fulcrum lining be set on the position of annular hole, be connected with the bottom wall of accommodating cavity.
As a further improvement of the present invention, the absorber rod passes through the fixture nut and lateral force that top is arranged in
Set lining is fixed together, and the two sides of the fulcrum bushing pass through the bottom wall and absorber rod of lateral clamp sleeve and accommodating cavity
It is connected.
As a further improvement of the present invention, the depth of the accommodating cavity is 30-60mm.
Beneficial effects of the present invention: the inner space that the present invention takes full advantage of air spring damper establishes Lever machine
Structure not only provides the demand of lateral force under the premise of meeting space and limiting for air bump, slows down to air bullet
Spring damage, and it is small to change range.Structure design simultaneously facilitates the maintenance of air spring assembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of an embodiment of the present invention；
Wherein: 1- absorber rod, 2- lateral force set lining, 3- shock absorber cylinder, 4- fulcrum bushing, 5- air spring upper cover, 500- hold

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.
It is a kind of to provide the air spring vibration damper assembly of lateral force, including shock absorber body based on lever mechanism, it is described
Absorber rod 1 is provided in shock absorber body inside it, absorber rod 1 described in the embodiment of the present invention is arranged in axis
The position of line.The both ends of the absorber rod 1 are connected with lateral force set lining 2 and shock absorber cylinder 3 respectively, further include being fixed on to subtract
The fulcrum bushing 4 for shaking 1 middle position of device bar is used as fulcrum, and the lateral force set lining 2 and shock absorber cylinder 3 and the fulcrum serve as a contrast
Set 4 cooperates, and applies contrary active force from the both ends of absorber rod 1 respectively, designed this lever mechanism makes
The lateral rigidity that compresses for obtaining lateral force bushing 2 is acted on shock absorber cylinder 3 by fulcrum bushing 4, is subtracted for entire air spring
It shakes device and lateral force is provided.
Wherein, in the lever mechanism, the distance between described lateral force set lining 2 to fulcrum bushing 4 is set as d1,
The shock absorber cylinder 3 is set as d2 to the distance between fulcrum bushing 4, in order to effectively provide lateral force, when design d1 with
The ratio of d2 should be controlled in 1:3~1:7.
The top of the shock absorber body is provided with air spring upper cover 5, the centre of the air spring upper cover 5
Position is equipped with the accommodating cavity 500 extended downwardly for the fixed lever mechanism from lateral force set lining 2 to 4 this section of fulcrum bushing,
Side wall and bottom wall and the air spring upper cover 5 of the accommodating cavity 500 are integrally connected, and top plan is provided with top pressure closure 8,
Its bottom wall is equipped with for the annular hole through absorber rod 1.The centre of accommodating cavity 500 is arranged in the lateral force set lining 2
In cavity；The position of annular hole is arranged in the fulcrum bushing 4, is connected with the bottom wall of accommodating cavity 500.Specific connection side
Formula is that the absorber rod 1 passes through the fixture nut 6 that top is arranged in and lateral force set lining 2 is fixed together, the branch
The two sides of point bushing 4 are connected by lateral clamp sleeve 7 with the bottom wall of accommodating cavity 500 and absorber rod 1.
In order to be suitable for providing different size of lateral force demand, can laterally be compressed by adjusting lateral force bushing 2 rigid
Degree can adjust the size of lateral force, can be solved by providing various sizes of lateral force set lining 2 in the embodiment of the present invention
The problem.The depth of the accommodating cavity 500 is greater than the absorber rod 1 and is located at the length in Container 500, described
The lateral force set lining 2 of 500 setting different heights in accommodating cavity, the fixture nut 6 can be along straight where absorber rod 1
Line moves up and down, and is adjusted according to lateral force set lining 2, so that lateral force set lining 2 is fastened in Container 500.The connection
Mode is also convenient for the replacement of lateral force set lining 2 simultaneously, since mostly use is elastic rubber material to lateral force set lining 2, with when
Between passage be easy aging, impact effect, therefore connection type provided by the present invention can easily replace aging or answer
The impaired lateral force set lining 2 of power.
