The further improvement lies in that: the central shaft and the runner plate are riveted into a whole and become a vulcanization assembly together with the rubber body.
The further improvement lies in that: the rubber plug comprises a bulge and a plug hole corresponding to the plug hole, and lips are arranged around the rubber plug.
The further improvement lies in that: the middle part of the outer shaft diameter of the rubber body is contracted into a first groove structure, the shell corresponding to the first groove structure is contracted into a second groove structure, and the second groove structure wraps the first groove structure.
The further improvement lies in that: and a check ring is further vulcanized in the rubber body, wherein the check ring is vulcanized in the rubber body at the end facing the cavity.
The further improvement lies in that: the diameter of the anti-backing ring is larger than the inner diameter of the second groove structure.
Has the advantages that:
the utility model adds silicon oil as damping liquid on the basis of rubber suspension, and adopts high viscosity silicon oil as damping liquid to realize low frequency damping lifting; the vulcanizing body assembly and the runner plate are integrated into a whole, the integrated vulcanizing body assembly and the runner plate are arranged in a metal shell with silicon oil damping fluid, vacuumizing is carried out after buckling, and then the rubber plug and the threaded plug are sequentially arranged for sealing.
The central shaft and the runner plate are pressed into a whole through riveting and become a vulcanization body assembly with the rubber body, so that the stable structure of the runner plate is ensured.
The rubber plug bulge and the plug hole are correspondingly plugged, lips are arranged around the rubber plug and are plugged with the thread plug in multiple ways, and liquid leakage is avoided.
The utility model discloses an extrusion metal casing and rubber body diameter are groove structure, and the anticreep realizes preventing the weeping simultaneously.
The anti-return ring is vulcanized in the rubber body, so that the phenomenon of return of the vulcanized body assembly can not occur when a driver jumps on a cab.
