Abstract

An elastic bearing includes a support and a thrust bearing. Each is provided with a fastening element and each are braced against each other by at least one elastic spring element of an elastomeric material and at least one damping device. The support includes a supporting body made of a tough material, which extends essentially transverse to the direction of the introduced vibrations. The thrust bearing includes a drum-shaped housing which essentially encloses the supporting body on all sides. The supporting body is adjoined by at least one ring-shaped damping element made of an elastomeric material which, under static preloading of the bearing, abuts on the front-side inner surfaces of the housing in a substantially stress-free manner. In the cylindrical recess of the damping element at least one elastic spring element is arranged axially on both sides of the supporting body. The elastic spring elements, under axial prestressing, are braced between the surface of the supporting body and the respective adjacent front-side inner surface of the housing.
