Abstract: A rack and pinion drive may comprise a housing without a thrust piece connector, as well as a toothed rack that has a toothing arrangement and is slidably mounted in the housing. A pinion may be rotatably mounted in a bearing in the housing, wherein the pinion is positioned along a longitudinal axis. The pinion may have a toothing arrangement that engages with the toothing arrangement of the toothed rack. A bearing arrangement for mounting the bearing in the housing may include a guide piece that abuts the housing and has an internal guide face. Likewise, the bearing arrangement may include a sliding piece that surrounds the bearing and has an external guide face. The external guide face of the sliding piece is guided at least by the internal guide face of the guide piece such that the sliding piece is slidable at least in a direction of the longitudinal axis. As a result, the pinion is adjustable in a direction of the toothed rack.

Abstract: A steering gear mechanism for motor vehicles may include a steering system housing in which a toothed rack is mounted and displaceable along a longitudinal axis. The toothed rack may be connected to steerable wheels of a motor vehicle and configured to pivot the steerable wheels. The toothed rack can include a first toothed segment that meshes with a first pinion of a pinion shaft, with the pinion shaft being connectable to a steering wheel via an input shaft. The toothed rack may further include a second toothed segment that is situated opposite the first toothed segment with respect to the longitudinal axis and engages with a second pinion. Further, an electric motor can drive the first pinion in a first direction, which by way of direct or indirect coupling causes the second pinion to rotate in a second direction opposite the first direction. The electric motor may drive a gear mechanism shaft that surrounds the pinion shaft and is connected to the pinion shaft by way of a gear mechanism.
