The end of second fixing end is seal-installed on by fluid sealant on the external part.
By structure design so, first fixing end only opens up and the center in the centre pilot shaft position
The compatible through hole of guiding axis plays good fixed function and elastic buffer is made so as to form structure is slidingly sealed
With；The end of second fixing end is seal-installed on by fluid sealant on the external part, and good sealing effect is also played
Fruit.
It is as a kind of perferred technical scheme, described to prevent from being located at institute in cover in the automobile absorber of the present invention
It states and is equipped with compaction cavum between the first fixing end and second fixing end, the centre pilot axis runs through the compaction cavum,
The cavity wall of the compaction cavum is accordion.
By structure design so, elastic telescopic may be implemented in the cavity wall of the compaction cavum, to play damping
Effect.
In the automobile absorber of the present invention, as a kind of perferred technical scheme, the vehicle transit disk with it is slow
It rushes between device shell equipped with compressed spring.
Still more preferably, for the set-up mode of the compressed spring, the applicant has also carried out further grinding
Study carefully improvement, to devise a kind of novel compressed spring set-up mode, specially：Technical side as one preferred
The specific set-up mode of case, the compressed spring is as follows：It is installed with the first spring base on the vehicle transit disk, described
One spring base is installed on the top rubber cushion, and second spring seat, the second spring are installed in the buffer housing
Cover for seat is loaded on the external part, and the compressed spring clamps between first spring base and the second spring seat.
By structure design so, the compressed spring can secondary buffer play cushioning effect, to reduce
The oil pressure of lubricating oil when buffer damping, reduces the pressure oscillation of oil lubrication system.
Certainly, it can also be not provided with the compressed spring between the vehicle transit disk and the buffer housing, this
Shi Wufei damping effects are in a slight decrease and the oil pressure of lubricating oil is all increases.It is further that the compressed spring, which is arranged,
It improves and improves.

When technique become it is simpler be easy, it is only necessary to the inner wall of guide cylinder is finished, in use, guide cylinder
It can be individually replaced guide cylinder after abrasion, without replacing entire buffer housing, greatly reduce maintenance cost, have
Good use value.
2, since buffer housing is equipped with gas-permeable channels, can be connected between guide piston and buffer housing outer
Boundary's air, generates back pressure when guide piston being avoided to retract, reduce energy loss, improves gas energy storage efficiency.
3, since the rear and front end of piston guide chamber is respectively equipped with front seal and rear seal, by centre pilot axis and delay
It rushes device shell to separate by front seal and rear seal, and front seal and rear seal all use rubber material, it can be with
The vibration for buffering centre pilot axis, avoids buffer housing from receiving the impact of centre pilot axis and vibrate aggravation.
4, due to being equipped with a guide pad in external part, guide pad is fixed on the inner wall of spacer, be provided on guide pad with
The compatible pilot hole of centre pilot axis, on the one hand, guide pad plays supporting role, improves the intensity of spacer, another party
Face, guide pad play guiding role.
5, due to being equipped with compressed spring between vehicle transit disk and buffer housing, secondary buffer plays damping work
With the oil pressure of lubricating oil when to reduce buffer damping reduces the pressure oscillation of oil lubrication system.
6, the power of lubricating oil system is provided by gas energy storage chamber, can also for draining into other oil sites, by impact force,
Save lubricating power, it is not necessary to frequently enable grease pump and lubrication can be realized, have very important significance.
As described above, the present invention provides a kind of automobile absorber, the automobile absorber passes through unique structure design
And mutual cooperation, to achieve many advantageous effects, auto industry field have a good application prospect and industry
Change productive potentialities, it may have good promotional value.
