A steering system for a vehicle includes a transmission cover on a steering gear housing. The cover is arranged adjacent to a bearing part. The side surface of the bearing part facing the transmission cover forms a support surface for the transmission cover.

Steering system for a vehicle

A steering system has a steering rod longitudinally displaceable in a housing and a steering motor acting on the steering rod via a ball screw drive. The steering rod has a recirculating ball thread interacting via spherical transmission elements with a transmission nut driven by the steering motor and that is rotatably mounted by a bearing arrangement with a pivot bearing having an inner ring to which a mechanism wheel is fixedly attached. The transmission nut is pivotably mounted on the mechanism wheel about a pivot axis oriented perpendicularly to the longitudinal axis of the steering rod, and has a curved joint section which interacts with a curved joint section of the mechanism wheel to form a pivoting bearing. In order to realize low-friction movement capability of the pivoting bearing, at least one of the joint sections has a sliding coating, and/or a lubricant is arranged between the joint sections.

The transmission nut is pivotably mounted on the mechanism wheel about a pivot axis oriented perpendicularly to the longitudinal axis of the steering rod, and has a curved joint section which interacts with a curved joint section of the mechanism wheel to form a pivoting bearing. An elastically deformed spring ring arranged between the joint sections provides freedom from play of the pivoting joint.

A steering system for a motor vehicle comprising a steering linkage, a steering drive, a gearbox transmitting a driving movement of the steering drive to the steering linkage, and a multi-piece housing that at least partially surrounds the steering linkage, the steering drive and/or the gearbox, having a drainage groove formed in a first contact surface of a first housing part of the multi-piece housing, the first contact surface being seated against a mating second contact surface of a second housing part of the multi-piece housing.
