Publication number: 20210380166Abstract: A motor vehicle (10), in particular an autonomous motor vehicle, includes a steering system (38, 30), a plurality of wheels (18, 20) that can be steered by means of the steering system (28, 30), and wheel housings (24, 26) for said wheels (18, 20). The steering system (28, 30) is designed such that the steering system steers the steerable wheels (18, 20) of a wheel pair in question in the same direction, in the case of joint steering to the left or right at a steering angle a up to a limit angle ag defined by the shape of the corresponding wheel housings (24, 26), and in opposite directions, in the case of steering to the left or right at a steering angle a exceeding the limit angle ?g.Type: ApplicationFiled: September 9, 2019Publication date: December 9, 2021Applicant: Schaeffler Technologies AG & Co.

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.

Publication number: 20180335089Abstract: A strut bearing, including: an axis of rotation; cap; a body portion; and a bearing fixed to the strut bearing cap and to the body portion. The cap includes: a first radial surface facing in a first axial direction; a plurality of ribs; a plurality of spaces, each space circumferentially disposed between a respective pair of ribs; and a plurality of radial recess surfaces. Each rib includes: a radial rib surface extending radially outwardly from the first radial surface; and a slant surface extending from the radial rib surface partly radially outwardly and partly in a second axial direction, opposite the first axial direction. Each radial recess surface: faces in the first axial direction; is circumferentially disposed between two respective ribs; and is off-set, in the second axial direction, from the first radial surface.Type: ApplicationFiled: May 16, 2017Publication date: November 22, 2018Applicant: Schaeffler Technologies AG & Co.

Patent number: 8894295Abstract: 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.Type: GrantFiled: July 16, 2013Date of Patent: November 25, 2014Assignee: Schaeffler Technologies AG & Co.
