  • Patent number: 11041530
    Abstract: A shaft bearing for mounting a shaft of a motor vehicle, having an inner sleeve, an outer body which surrounds the inner sleeve thereby forming a gap, and an elastomer body which connects the inner sleeve and the outer body elastically to one another. The inner sleeve may be embedded in the elastomer body and form a receiving opening for pressing in a bearing element. The inner sleeve may have at least one first deformation which is directed radially inwards in such a way that a shear gap is formed between the first deformation and the bearing element. An elastomer bead that may be formed when the bearing element is pressed in may be compressed within the shear gap.

  • Patent number: 9291228
    Abstract: A vibration absorber for damping vibrations of motor vehicle components. The vibration absorber comprises an absorber mass including a passage, and an elastomeric spring member inserted in the passage of the absorber mass. The elastomeric spring member comprises an outer sleeve connecting the elastomeric spring member to the absorber mass, and an inner sleeve for attachment to the motor vehicle component to undergo vibration absorption. An elastomer body interconnects the inner sleeve and the outer sleeve. The elastomeric spring member also includes a securing element. The vibration absorber includes stops that are spaced apart in an axial direction and that cooperate with the securing element to secure the absorber mass in the axial direction.

  • Publication number: 20070219002
    Abstract: A flexible coupling for torque-transmitting connection of two elements comprising a supporting body to which are assigned pick-up fixtures which are movably disposed relative to one another, to each pick-up fixture there is assigned at least one elastically deformable layer. Each pick-up fixture surrounds one at least partly spherically shaped elastic layer and a cylindrically shaped elastic layer, and wherein the layers cooperate during the relative movement of the pick-up fixtures. Such a flexible coupling finds use in an assembly.
