  • Patent number: 10029532
    Abstract: The invention relates to strut bearing with a cap and a guide ring which is mounted in a rotatable manner about a rotational axis (D) relative to the cap. An axial bearing is arranged between the cap and the guide ring, and the cap includes a soft component and a hard component. Furthermore, the soft component has at least two circumferential sealing lips which rest against the guide ring in a sliding manner in order to seal the axial bearing. According to the invention, the soft component is formed on a hard component end face oriented towards the guide ring, and a hard component end face oriented opposite the guide ring has a profile.

  • Patent number: 9869351
    Abstract: A spring strut bearing with a cap and with a guide ring which is mounted in a rotatable manner relative to the cap about a rotational axis (D), an axial bearing being arranged between the cap and the guide ring. The cap has a seal, and the cap is connected to the guide ring at an inner diameter of the cap by a snap-in connection. The cap has a first element of the snap-in connection, and the guide ring has a second element of the snap-in connection, said elements engaging into each other in a formfitting manner. The first element is designed as a two-component part, the soft component of which engages into the second element in a formfitting manner and the hard component of which forms a reinforcement of the soft component.

  • Patent number: 9234541
    Abstract: A suspension strut bearing (1) having two assemblies (11, 12), which are counter-rotatable about a longitudinal axis (z) and centered with respect to each other, including two bearing rings (2, 3), which are each allocated to one assembly (11, 12) and counter-rotatable when mounted, and a sealing device (8). In order to decouple the sealing device (8) and the centering from each other with respect to the function thereof and still provide said parts cost-effectively, a single-piece, two-component element (5) is provided on one of the bearing rings (2), which element centers the assemblies (11, 12) one over the other by a first component having a greater stiffness than a second component and forms the sealing device (8) with the second component.

  • Patent number: 8992094
    Abstract: A suspension strut bearing including a guide ring arranged along a suspension strut axis, and a cap. The guide ring is configured for mounting a coil spring, and the cap is configured for supporting the suspension strut bearing on an undercarriage of an automotive vehicle. The guide ring includes a radial flange and further includes a guide nozzle adjoining the radial flange, the guide nozzle serving to guide said coil spring, the suspension strut bearing further including a thrust bearing arranged between the radial flange of the guide ring and the cap. The guide ring includes a reinforcement ring spray coated with a plastic, which reinforcement ring further includes a bushing section for reinforcing the guide nozzle and an integrally formed adjoining radial collar for reinforcing the radial flange, wherein the reinforcement ring is configured as a bearing part of the thrust bearing.

  • Patent number: 8894295
    Abstract: A suspension strut bearing includes a guide ring, a cap, and a thrust bearing for an axial mounting of the guide ring on the cap. The plastic guide ring is reinforced with a reinforcement ring including a radial flange, an axial guide nozzle adjoining the radial flange, a bushing section for reinforcing the guide nozzle and an integrally formed radial collar adjoining the guide nozzle for reinforcing the radial flange. A sliding seal is made out of a softer plastic and sprayed onto the radial flange of the guide ring, a sealing lip of the sliding seal being arranged around the guide ring and bearing against a peripheral surface of the cap, the radial collar of the reinforcement ring forming an integrally configured raceway of the thrust bearing. The radial collar includes recesses arranged spaced along a periphery of the radial collar, through which recesses the softer plastic penetrates.
