Abstract
Abstract An elastic pivotal bearing support of a structural part carrying out exclusively angular movements, particularly in individual wheel suspensions of motor vehicle wheels, which absorbs forces directed axially and/or radially to the pivot axis and which transmits the same into a frame; the pivot bearing support is thereby equipped with two coaxial sleeves, namely, an inner sleeve and an outer sleeve which are under radial prestress from the presence of a rubber-elastic material with a layer thickness sufficient to absorb shocks; one sleeve is connected with the frame and the other with the structural part, whereby the two sleeves immovably adhere at the contact surface of the rubber-elastic material during pivotal movements of the structural part; at least one axial collar is provided which is moved along with the structural part and at least one further corresponding axial collar is provided which is moved along with the frame; a layer of rubber-elastic material of shock-absorbing thickness is arranged between the two collars whereby the axial cushion or cushions formed thereby is or are separate from the radial cushion formed by the rubber-elastic material between the inner and outer sleeve and/or an axial slide bearing is arranged between an axial collar or a respective one of each of the corresponding axial collars and the associated axial cushion.
