Description
Technical Field
The utility model relates to the technical field of automobile chassis suspensions, in particular to an assembled rubber spherical hinge.
Background
The NVH performance of the whole vehicle is always used as an index for evaluating the performance of the vehicle, and with the continuous development of the whole vehicle technology, bushing parts taking rubber as a buffer material are widely applied to the whole vehicle. The rubber bushings are generally installed at the hinged position of a vehicle, various forces and moments are transmitted, meanwhile, the rubber bushings can also play a role in damping and buffering, most of common bushing forming processes adopt framework and rubber vulcanization forming, the rubber bushings are connected with the framework through adhesives, and the service life of the rubber bushings is directly determined by the bonding performance. In the actual production of the rubber bushing, oil stain, corrosion, roughness, process control parameters, environmental factors and the like on the surface of the framework can influence the bonding performance, the number of influencing factors is large, the consistency is poor, and the product cost is increased.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, the present invention provides an assembled rubber ball joint
In order to realize the purpose, the technical scheme of the utility model is as follows: the utility model provides an assembled rubber ball pivot, which comprises an outer cover, rubber sleeve and dabber, the outside cover of dabber has the rubber sleeve, the outside cover of rubber sleeve has the overcoat, and the overcoat internal diameter adopts interference fit with the rubber sleeve external diameter, the external diameter of dabber and the internal diameter of rubber sleeve adopt interference fit, the dabber at rubber sleeve both ends has set gradually inside sunken annular circular bead and for the axle retaining ring groove from inside to outside, the rubber retaining ring is located annular circular bead, for the axle retaining ring is located for the axle retaining ring inslot, and the rubber retaining ring is hugged closely to for the axle retaining ring, the rubber sleeve tip is hugged closely to the rubber retaining ring.
Further, the diameter of the rubber retainer ring is larger than that of the shaft retainer ring.
Further, the width of the rubber retainer ring is larger than that of the rubber sleeve.
Further, the diameter of the retainer groove for the shaft is smaller than the diameter of the annular shoulder.
Further, the mandrel is of a tubular or rod-like structure.
Due to the adoption of the technical scheme, the rubber bushing structure is optimized, the original integral vulcanization bonding structure is cancelled, the interference fit installation and the check ring fixed installation are adopted, and the product consistency is improved.
