Abstract
The invention discloses a kind of dust cover for damper, including the cover body in corrugated tube shape, one end of the cover body is provided with to close up and managed, the other end is coordinated by connector and absorber spring seat to be fixed, the cover body includes the multiple crests and trough being sequentially connected, the cover body is located at is interval with some web frames at the trough of central shaft, and the web frame is annular tubular structure.The present invention on the cover body of damper dust-proof cover by being arranged at intervals web frame, so as to effectively improve the radial rigidity of cover body, prevents damper dust-proof cover negative pressure from deforming；Web frame is annular hollow pipe, and size design is reasonable, lighter in weight, does not interfere with cover body and makees cross-direction shrinkage action with damper.
Description
Technical field
The present invention relates to auto parts field, and in particular to a kind of dust cover for damper.
Background technology
Damper is mechanical parts most accurate and complicated in automobile suspension system, the quality of its quality
Directly affect ride comfort, operational stability and the comfortableness of vehicle traveling.Damper dust-proof cover
It is very important part in vibration damper assembly, its effect is can effectively to prevent mud, sand
Grain, dust etc. corrode oil leak, abnormal sound to caused by damper.
In place of the existing dust cover for damper comes with some shortcomings in use, by
Be gum material in dust cover, the rigidity of its radial direction is smaller, vehicle under steam, if
It is greatly and rapid that wheel hop acutely make it that the inner space of damper dust-proof cover changes, and now holds
Easily because damper dust-proof cover interior or exterior space gas exchanges not in time and caused by damper dust-proof cover
Air pressure is less than outside air pressure, and the damper dust-proof cover of gum material is because of its radial direction
Rigidity is smaller to be not enough to overcome excessive negative pressure deformation force so that damper dust-proof cover negative pressure becomes
Shape, cause dust cover to be involved in shock absorber piston connecting rod or buffer body, ultimately cause dust cover and tear
Split or vibration damper assembly damages.
The content of the invention
It is an object of the invention to overcome the above-mentioned problems in the prior art, there is provided Yi Zhongyong
In the dust cover of damper, its radial rigidity is higher, can prevent dust cover negative pressure deformation
Appearance.
To realize above-mentioned technical purpose and the technique effect, the present invention is by following skill
Art scheme is realized：
A kind of dust cover for damper, including the cover body in corrugated tube shape, the cover body
One end is provided with to close up and managed, and the other end is coordinated by connector and absorber spring seat to be fixed, described
Cover body includes the multiple crests and trough being sequentially connected, and the cover body is located at the ripple close to central shaft
Some web frames are interval with paddy, the web frame is annular tubular structure；It is described
Web frame is metallic framework, and it is crosslinked on the cover body by sulfuration process；Adjacent two
A trough is separated between the individual web frame.
Further, the thickness of the cover body is 4~8mm.
Further, the external diameter of the web frame is 2.6~3.2mm, internal diameter is 1.2~
1.8mm。
The beneficial effects of the invention are as follows：
1st, by being arranged at intervals web frame on the cover body of damper dust-proof cover, so as to effectively carry
The radial rigidity of high cover body, prevent damper dust-proof cover negative pressure from deforming so that damper dust-proof cover
Preferably play the effect such as dust-proof, waterproof.
2nd, web frame is annular hollow pipe, and size design is reasonable, lighter in weight, does not interfere with
Cover body makees cross-direction shrinkage action with damper.
Certainly, any product for implementing the present invention it is not absolutely required to reach above-described simultaneously
All advantages.

All other embodiment that logical technical staff is obtained under the premise of creative work is not made,
Belong to the scope of protection of the invention.
Referring to shown in Fig. 1-4, the present invention is a kind of dust cover for damper, including in ripple
The cover body 1 of line tubulose, one end of cover body 1 are provided with closing in pipe 2, the other end by connector 3 with
Absorber spring seat, which coordinates, to be fixed, and cover body 1 includes the multiple crests and trough being sequentially connected, cover
Body 1 is located at is interval with some web frames 4, web frame 4 at the trough of central shaft
For annular tubular structure.
Wherein, the thickness of cover body 1 is 4~8mm.
Wherein, the external diameter of web frame 4 is 2.6~3.2mm, and internal diameter is 1.2~1.8mm.
Wherein, web frame 4 is metallic framework, and it is crosslinked on cover body 1 by sulfuration process.
Wherein, between two adjacent web frames 4 between be separated with a trough.
One of the present embodiment has particular application as：Between on the cover body 1 of damper dust-proof cover
Every setting web frame 4, so as to effectively improve the radial rigidity of cover body 1, dust prevention of vibration absorber is prevented
Cover negative pressure deforms so that and damper dust-proof cover preferably plays the effect such as dust-proof, waterproof, and then
