Abstract
The utility model relates to an automobile chassis suspension shock absorber. The utility model relates to a shock absorber which is hung on an automobile chassis, which solves the problem that the relative movement of a piston rod and a guide device on the existing automobile chassis suspension shock absorber is likely to produce the abrasion. A check valve is arranged on the bottom inside a shell, a rubber check valve plate is arranged above the check valve, an oil cylinder is arranged above the rubber check valve plate, a piston is arranged inside the oil cylinder, the piston is provided with an oil inlet hole, the rubber piston valve plate is arranged above the piston, the guide device is arranged on the upper end of the oil cylinder, the lower end of the piston rod runs through the rubber piston valve plate to be connected with the piston, the upper end of the piston rod sequentially runs through the guide device, an oil seal and a cover to be arranged outside the shell, an oil seal is arranged in a groove of the cover, a hole, contacted with the piston rod, of the guide device is provided with a seal ring groove, and an O-shaped seal ring is arranged in the seal ring groove. The automobile chassis suspension shock absorber is used for being hung on the automobile chassis.
Description
Technical field
The utility model relates to a kind of vibration damper hanging for automobile chassis.
Background technique
Between piston rod on existing automobile chassis suspension damper and guider, there is no seal ring, the relative movement of piston rod and guider easily produces wearing and tearing, thereby reduces the working life of vibration damper.
Model utility content
The utility model is to solve piston rod on existing automobile chassis suspension damper and the relative movement between guider easily produces the problem of wearing and tearing, and a kind of automobile chassis suspension damper is provided.
The utility model comprises housing, oil cylinder, piston, check valve, rubber check valve sheet, rubber piston valve block, guider, O RunddichtringO, piston rod, oil sealing and lid, check valve is arranged on the bottom in housing, rubber check valve sheet be arranged on check valve above, oil cylinder be arranged on rubber check valve sheet above, piston is arranged in oil cylinder, piston is provided with oil inlet hole, rubber piston valve block is arranged on above piston, guider is arranged on the upper end of oil cylinder, the lower end of piston rod is connected with piston through rubber piston valve block, the upper end of piston rod is successively through guider, oil sealing and lid are arranged on outside housing, oil sealing is arranged in the groove of lid, in the hole that guider contacts with piston rod, be provided with seal groove, O RunddichtringO is arranged in seal groove.
The utlity model has following beneficial effect:
The utility model has increased O RunddichtringO between piston rod and guider, not only plays seal action, has also avoided piston rod wearing and tearing, has extended the working life of vibration damper.
Accompanying drawing explanation
Fig. 1 is the main sectional view of overall structure of the present utility model, and Fig. 2 is the plan view of piston 3.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1, present embodiment comprises housing 1, oil cylinder 2, piston 3, check valve 4, rubber check valve sheet 5, rubber piston valve block 6, guider 7, piston rod 9, oil sealing 10 and lid 11, check valve 4 is arranged on the bottom in housing 1, rubber check valve sheet 5 be arranged on check valve 4 above, oil cylinder 2 be arranged on rubber check valve sheet 5 above, piston 3 is arranged in oil cylinder 2, piston 3 is provided with oil inlet hole 3-1, rubber piston valve block 6 is arranged on above piston 3, guider 7 is arranged on the upper end of oil cylinder 2, the lower end of piston rod 9 is connected with piston 3 through rubber piston valve block 6, the upper end of piston rod 9 is successively through guider 7, oil sealing 10 and lid 11 are arranged on outside housing 1, oil sealing 10 is arranged in the groove that covers 11, it is characterized in that: described vibration damper also comprises O RunddichtringO 8, in the hole that guider 7 contacts with piston rod 9, be provided with seal groove 8-1, O RunddichtringO 8 is arranged in seal groove 8-1.When use, housing 1 is hung and joined with car, piston rod 9 joins with car body wheel top panel beating, and housing 1, under the motion of car, changes housing 1 and piston rod 9, is provided with spring in vibration damper outside.After being subject to weight, wheel can move up and down, at this moment spring meeting pinking, and this vibration damper will be alleviated the pinking of spring.
Embodiment two: in conjunction with Fig. 2, present embodiment is described, the piston 3 of present embodiment is provided with adjusting oil mass hole 3-2 along circumferential outer surface.Other composition and connection are identical with embodiment one.
Working principle: be that check valve 4 is opened in the time that piston rod 9 drives piston 3 to move upward, the oil between oil cylinder 2 and housing 1 enters in oil cylinder 2 along check valve 4.In the time that piston rod 9 drives piston 3 to move downward, check valve 4 is closed, and now the oil in oil cylinder 2 flows upward along the through hole 3-1 on piston 3.In the time that piston rod 9 is worked for the second time (while again moving upward), on piston, valve block 6 is closed.Now along the adjusting oil mass hole 3-2 on piston 3, the check valve 4 below piston 3 moves the oil in oil cylinder 2, now produces pressure and dissolve the outburst ability of housing 1 outer spring, alleviates the stationarity of car body.In the time that piston 3 is up, because the oil of oil cylinder 2 moves, adjustment meeting produces certain pressure below guider 7.
