By structure design so, on the one hand, the guide pad serves supporting role, the strong of the spacer is improve
Degree；On the other hand, the guide pad serves guide effect, it is well known that the centre pilot axle extension elongation is longer, and it is disturbed
Degree deformation is bigger, can cause centre pilot axle off-axis in telescopic process, so as to cause the infringement to potted component,
The service life of potted component is reduced, and the guide pad reduces institute then into a fulcrum of the centre pilot axle
The deflection deformation of centre pilot axle is stated, and then extends the service life of amortisseur of the present invention.
In the automobile absorber assembly of the present invention, used as a kind of preferred technical scheme, the dust cover is rubber
Glue material or macromolecular elastomer material.
Wherein, the common used material that the elastomeric material and macromolecular material right and wrong are usually advised, for example, can be various conjunctions
Into elastomeric material and macromolecular elastomer material (such as styrene analog thermoplastic elastomer material etc.), here is no longer carried out in detail
Description.
In the automobile absorber assembly of the present invention, in the automobile absorber assembly of the present invention, as one
Preferred technical scheme is planted, it is described to prevent from being located to be provided between first fixing end and second fixing end in cover compressing sky
Chamber, the centre pilot axle runs through the compaction cavum, and the cavity wall of the compaction cavum is accordion.
By structure design so, the cavity wall of the compaction cavum can realize elastic telescopic, so as to serve damping
Effect.
Certainly, can also be without arranging the compression spring between the vehicle transit disk and the buffer housing, this
Shi Wufei damping effects are in a slight decrease, and all increases of oil pressure of lubricating oil.It is further to arrange the compression spring
Improve and improve.
As described above, the invention provides a kind of automobile absorber assembly, the automobile absorber assembly is by uniqueness
Structure design and cooperate, so as to achieve many Advantageous Effects, for example：

Storage energy, and the process also improves damping effect simultaneously；Again due to being provided with guide cylinder so that buffer housing is processed
When technique become it is simpler easily, it is only necessary to being directed to the inwall of cylinder carries out polish, in use, guide cylinder
Guide cylinder can be individually replaced after abrasion, without whole buffer housing is replaced, maintenance cost is greatly reduced, be had
Good use value.
2nd, because buffer housing is provided with gas-permeable channels, can cause to connect outer between guide piston and buffer housing
Boundary's air, it is to avoid guide piston produces back pressure when retracting, and reduces energy loss, improves gas energy storage efficiency.
3rd, because the rear and front end in piston guide chamber is respectively equipped with front seal and rear seal, by centre pilot axle with it is slow
Rush device housing to separate by front seal and rear seal, and front seal and rear seal all adopt elastomeric material, can be with
The vibration of buffering centre pilot axle, it is to avoid buffer housing receives the impact of centre pilot axle and vibrates aggravation.
4th, due to being provided with a guide pad in external part, guide pad is fixed on the inwall of spacer, be provided with guide pad with
The pilot hole that centre pilot axle is adapted, on the one hand, guide pad serves supporting role, improves the intensity of spacer, the opposing party
