  • 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: 9969232
    Abstract: A suspension strut mount (1), with a mount arranged between a guide ring (2) and a cap (3). The guide ring (2) and the cap (3) are connected to each other by a snap-on connection (5) that has at least one torsion snap-fit hook (6, 21) that is arranged via a holder (7) that can be torsionally bent on one of the guide ring (2) or the cap (3) and engages, in the assembled state, in an undercut (8) on the other of the guide ring (2) or the cap (3).

  • 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.
