Publication number: 20210122410Abstract: A steering head bearing arrangement for mounting a wheel module for a motor vehicle is provided with a steering rod connectable to a steering actuator and a wishbone, and a bearing flange connectable with a support frame of the motor vehicle, first and second roller bearings arranged in the bearing flange for mounting the steering rod, and a retaining ring screwed onto the steering rod for biasing the second roller bearing against the first roller bearing. By biasing the substantially spaced apart roller bearings against each other by means of the screwed-on retaining ring, radial and axial play of the steering rod in the bearing flange can be largely eliminated, thereby allowing to avoid wear-intensive peak stresses and allowing robust mounting of a steering rod of a motor vehicle.Type: ApplicationFiled: March 11, 2019Publication date: April 29, 2021Applicant: Schaeffler Technologies AG & Co.

Publication number: 20210023899Abstract: A wheel module for a motor vehicle is provided with a wheel, a steering rod which can be rotatably mounted on a supporting frame of the motor vehicle for transmitting a steering motion to the wheel, a wishbone connected to the steering rod for forming an articulation point radially offset relative to the wheel, a rocker articulated to the articulation point of the wishbone and to the wheel, and a shock absorber connected to the rocker and the wishbone for damping vibration of a relative movement of the wheel. The shock absorber, in particular including a chassis spring, is arranged to be axially offset in the axial direction of the wheel relative to the wheel. With the shock absorber connected to the wheel and the wishbone and arranged next to the wheel, a large steering angle for a motor vehicle is possible with a small installation space.Type: ApplicationFiled: March 26, 2019Publication date: January 28, 2021Applicant: Schaeffler Technologies AG & Co.

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.
