Patent number: 10029532Abstract: 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.Type: GrantFiled: March 2, 2015Date of Patent: July 24, 2018Assignee: Schaeffler Technologies AG & Co.

Patent number: 9869351Abstract: 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.Type: GrantFiled: September 2, 2014Date of Patent: January 16, 2018Assignee: Schaeffler Technologies AG & Co.

Patent number: 9234541Abstract: 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.Type: GrantFiled: January 21, 2013Date of Patent: January 12, 2016Assignee: Schaeffler Technologies AG & Co.
