摘要： The disclosure relates to a steer-by-wire system for a motor vehicle including a steering rod, an electric servo unit configured to move the steering rod, and a sliding bearing which radially supports the steering rod in a housing. The housing, the sliding bearing, and the steering rod have complementary geometries whereby the steering rod is prevented from rotating. The sliding bearing includes multiple segments in the circumferential direction, at least one segment of the multiple segments is a sliding bearing location for the radial support. At least one segment of the multiple segments is a first supporting element configured to prevent rotation in one direction of rotation. At least one segment of the multiple segments is a second supporting element configured to prevent rotation in the opposite direction of rotation.

摘要： A steering system for steering a wheel of a vehicle includes a track rod for deflecting the wheel, a rack which, by axial movement, leads to control of the track rod, and a housing. The rack is at least partially arranged within the housing. The rack has a convex and/or concave cross-sectional portion. The housing-mounted complementary geometry includes a complementary concave and/or convex shaping, as a result of which a form-fitting connection is produced for realizing the twist prevention.
