Disclosed is a steering gear for a power steering system of a vehicle, comprising a component that is mounted axially displaceably in a housing of the steering gear, a tie rod fixed in an articulated manner on at least one axial end of the component by way of a joint, wherein a rotational center of the joint is disposed on a radially directed adapter part laterally offset with respect to a central longitudinal axis of the axially displaceable component, and the adapter part is fixed to the axially displaceable component by way of a shaft-hub connection, which is fastened on the axial end of the axially displaceable component using a nut on an external thread so as to provide a steering gear that has a high-strength, play-free connection between the axially displaceable component thereof and the adapter part, and which is easy to produce, the shaft-hub connection being formed by a play-free, conical serrated connection.

Steering gear

A roller bearing assembly for supporting a shaft axially and radially in a rack includes a roller bearing with a carrier, a portion of which is supported at the rack with an element with elastomeric properties being interposed between a support for the rack and the portion of the carrier. In order to indicate a roller bearing, which supports the shaft axially and radially, and makes an inclined position of the shaft possible without causing straining of the system of shaft, roller bearing and rack, the element with elastomeric properties, viewed in the tangential (circumferential) direction of the roller bearing, has at least a first region, the stiffness of which is different from that of the remaining tangential (circumferential) region.

Roller bearing

A power-steering system, e.g., for a motor vehicle, having an electric motor, which transmits a steering-assist force via a belt transmission to a ball-screw transmission for displacing vehicle wheels, includes a cam, via which the ball-screw transmission and/or electric motor is supported in a steering-gear housing. The tension of a belt of the belt transmission is adjustable by rotating the cam in the steering-gear housing. The cam has at least one cutout on the circumference, and/or the steering-gear housing has at least one cutout in its inner wall. A locking element may be inserted into the cutout, in order to fix the cam in position with respect to the steering-gear housing. After being inserted, the locking element is operatively connected to the cam and the steering-gear housing.
