  • Patent number: 5340220
    Abstract: A pivoting bearing for mounting pull rods in motor vehicles, which includes a metallic housing (2) with a cylindrical inner jacket, a metallic inner part (1), and an elastomer body (3) arranged between the housing (2) and the inner part (1). The elastomer body (3) compensates axial, radial, and cardanic movements of the housing (2) in relation to the inner part (1) by molecular deformation. The elastomer body (3), which cooperates with the cylindrical inner jacket of the housing radially in the outward direction, is arranged adheringly on the inner part (1) and is pre-tensioned axially between plate rings (4, 5). The external diameter of the plate rings (4 and 5) is undersized compared with the internal diameter of the inner jacket of the housing. A sliding surface is obtained on the cylindrical outer jacket of the elastomer body under the axial pre-tensioning of this. This sliding surface permits rotary movement of the inner part (1) in the housing (2).
