Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to Fig.1, Fig. 2 is a kind of damper disclosed by the utility model, including working cylinder 1, and sliding is set in working cylinder 1
It is equipped with piston rod 2, piston rod 2 is parallel to the length direction setting of working cylinder 1 and one end is pierced by working cylinder 1, and piston rod 2 is pierced by
One end of working cylinder 1 is provided with step, and the lesser one end of 2 diameter of piston rod is located at the end position of piston rod 2, while piston rod
2 end thread is connected with lifting lug 7, and lifting lug 7 is folded with pop-up between the step on one end and piston rod 2 of working cylinder 1
Disk 3, the other end of working cylinder 1 are equally threaded with lifting lug 7 and are folded with lower tray 4 between lifting lug 7 and working cylinder 1, on
It is supported between pallet 3 and lower tray 4 and is equipped with spring 6, it is sliding between working cylinder 1 and piston rod 2 that piston rod 2 is pierced by 1 one end of working cylinder
Shifting is arranged with cushion 8, is interference fitted between cushion 8 and piston rod 2.
Damper during the installation process, first assembles working cylinder 1 and piston rod 2, and cushion 8 is sheathed on piston
On bar 2, then the lifting lug 7 of 4 one end of lower tray 4 and lower tray is assembled, and 6 one end of spring is butted in lower tray 4 and
It is sheathed on outside working cylinder 1, is later squeezed spring 6 using specific purpose tool, the other end of spring 6 is made to be lower than the end of piston rod 2,
Top tray 3 is penetrated from the end of piston rod 2 again, makes it closely on the step of 2 end of piston rod, lifting lug 7 is finally screwed into work
The end of stopper rod 2 is clamped in top tray 3 between the step of piston rod 2 and lifting lug 7, at this time trip spring 6, and spring 6 will be with pre-
The state of compression is butted between top tray 3 and lower tray 4.
The damper of such structure is installed on vehicle, when vehicle jolts, with vehicle body vertical tremor, piston rod
2 slide flexible in working cylinder 1, to drive top tray 3 to squeeze spring 6 close to or far from lower tray 4, piston rod 2 is contracting
Into in the process, when the distance of 2 retraction of piston rod is larger, cushion 8 close to working cylinder 1 end thereof contacts to working cylinder 1, and
It is slid to piston rod 2 close to 3 one end of top tray under the promotion of working cylinder 1, due to being interference fitted between cushion 8 and piston rod 2,
Therefore sliding is more difficult, this slows down the speed in the retraction working cylinder 1 of piston rod 2 to a certain extent, to reduce vehicle
Body jolts, and the buffering effect of cushion 8 is more preferable.When piston rod 2 is persistently retracted to utmostly, cushion 8 is barred from work
Make between cylinder 1 and top tray 3, avoid and rigid impact occurs between top tray 3 and working cylinder 1, protects damper, and by
It is sheathed on piston rod 2 in cushion 8, therefore replacement is convenient when aging occurs for cushion 8.
It with piston rod 2 is that the center of circle is arranged in cushion 8 to further enhance the buffering effect of cushion 8 referring to Fig. 3
There is the compression chamber 81 of multiple tracks annular, piston rod 2 is parallel in each compression chamber 81 and is evenly provided with several elastic components 82, this is practical
Elastic component 82 in this novel embodiment is rubber spring.
When cushion 8, which is located in, to be extruded between working cylinder 1 and top tray 3, compression chamber 81 plays absorption vibration simultaneously
Reduce the effect of pressure by deformation, elastic component 82 can play the role of further resilient support again, guarantee compression chamber 81
Restore shape after being squeezed.
Referring to Fig. 4, lifting lug 7 includes that the outer ring 71 being coaxially arranged and inner ring 72, the annular outer wall of outer ring 71 are vertically connected at
The end of piston rod 2 is folded with elastic interlayer 73 between outer ring 71 and inner ring 72, fixed between elastic interlayer 73 and outer ring 71 to connect
Joint bearing 74, outer ring 71 are the outer ring of bearing 74, and the inner ring of bearing 74 is fixedly connected on the outer diameter of elastic interlayer 73.
Elastic interlayer 73 plays buffering when can generate biggish pulling force between the installing component and damper on automobile
With the effect of protection, the rigid contact between the connecting component on automobile and lifting lug 7 is avoided, preferably protects lifting lug 7.
Referring to Fig.1, it is protruded in marginal position equipped with a circle side block 31, side block 31 in top tray 3 and 4 relative direction of lower tray
Internal diameter be greater than the diameter of the complete compressive state of spring 6, top tray 3 and 4 opposite side of lower tray are fixed viscous to be equipped with rubber pad 5, rubber
The thickness of rubber mat 5 is less than the height of side block 31.
Side block 31 avoids being against 3 He of top tray in 6 loading process of spring from the installation site of 6 outside limited spring 6 of spring
Position in lower tray 4 occurs sliding and causes 6 liang of side compressions of spring uneven, can not better play the effect of damping.Rubber
Rubber mat 5 both make to avoid between spring 6 and top tray 3 and lower tray 4 for flexible contact caused by rigid contact spring 6 not
Disconnected compression and the abrasion in stretching process.
Referring to Fig.1, soft dust-proof cover 9 is arranged on damper, lifting lug 7 is exposed to 9 outside of soft dust-proof cover.
The implementation principle of the present embodiment are as follows: soft dust-proof cover 9 can allow for piston rod 2 to stretch out or retract in working cylinder 1 and
Do not interfere the normal work of damper, at the same soft dust-proof cover 9 again can pollution from damper outer barrier dust to damper,
To preferably protect damper；The outside that lifting lug 7 is exposed to soft dust-proof cover 9 facilitates the installation of damper.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
