It can.
Still more preferably, for the set-up mode of the compressed spring, the applicant has also carried out further grinding
Study carefully improvement, so that a kind of novel compressed spring set-up mode is devised, specifically: technical side as one preferred
The specific set-up mode of case, the compressed spring is as follows: it is fixedly installed with the first spring base on the vehicle transit disk, described
One spring base is installed on the top rubber mat, and second spring seat, the second spring are fixedly installed in the buffer housing
Cover for seat is loaded on the extension end, and the compressed spring clamps between first spring base and the second spring seat.
So setting may make the stretching, extension of compressed spring and restore and more buffers, is gentle, further reduces vibration, mentions
High vehicle riding comfort.
Certainly, it can also be not provided with the compressed spring between the vehicle transit disk and the buffer housing, this
Shi Wufei damping effect is 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.
As described above, the automobile absorber assembly passes through unique the present invention provides a kind of automobile absorber assembly
Structure design and mutual cooperation, so that many advantageous effects are achieved, such as:
1, due to be provided with reset spring associated with centre pilot axis and gas energy storage chamber, when vehicle transit disk by
When impact, centre pilot axis retraction, compression reseting spring eliminates partial vibration, and with the retraction of centre pilot axis, compression
Air in piston compression piston compression chamber, so that these compressed airs enter gas energy storage chamber by the second breather check valve,
Energy is stored, 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 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 atmosphere, 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 extension end, 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, thus when reducing buffer damping lubricating oil oil pressure, reduce 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 which frequently enabling grease pump can be realized lubrication, have very important significance.
As described above, the automobile absorber assembly passes through unique the present invention provides a kind of automobile absorber assembly
Structure design and mutual cooperation, so that many advantageous effects are achieved, before auto industry field has good application
Scape and industrial production potential, it may have good promotional value.
