Abstract
An elastomeric bush bearing, with hydraulic damping, comprises a metallic inner part (), an elastomeric bearing element () encompassing the inner part () with a cage () for reinforcing the bearing element () vulcanized thereto. At least two chambers (), for accommodating a fluid damping medium, are separated from one another by partitions (), constructed between the bearing element (), adhesively bonded to the inner part () by the vulcanization, but are mutually connected by a damping medium channel (). A prestressing is applied to the elastomer of the bearing element (). However, the prestressing is not applied over the bearing shell (), but instead over the cage (). Calibration takes places thus by a pressure force exerted on the cage, before assembly of the bearing element () in the outer shell (), which is a deviation from the state of the art.
