摘要： The invention relates to a rotary shift valve (1) for servo-assisted steering systems of motor vehicles, which valve comprises a valve rotor (2) which is joined to a valve input member (4) in a non-rotating manner. A control bush (3) is joined to a valve output member (7) in a non-rotating manner. These two valve elements are arranged coaxially such that they are able to move within each other and can be rotated in relation to each other maximally about the rotational travel of a backlash coupling (6). The two valve elements further have longitudinal control ports (8, 10) which cooperate so as to control a hydraulic fluid moving towards and away from two working chambers of a servo-motor and to a return flow connection (18) for a hydraulic fluid container. The valve rotor (2) is connected with the valve output member (7) via a torsion bar spring (12). The longitudinal control ports (8, 10) of the radially interior valve element, which are connected with the return flow connection (18), are connected to an interior space (13) of the radially interior valve element. In said interior space (13) the torsion bar spring (12) is mounted by means of an anti-friction bearing (14). The return flow from the interior space (13) of the radially interior valve element to the return flow connection (18) passes through the anti-friction bearing (14) and the backlash coupling (6).

摘要： The invention relates to a rack-and-pinion steering (1), particularly for a motor vehicle, comprising a steering-gear housing (2) and a pinion (3) that is mounted inside the steering-gear housing (2). A rack (4), which engages with the pinion (3) via a toothing (5), is mounted inside the steering-gear housing (2) in an axially displaceable manner. The rack-and-pinion steering (1) has a lubrication by circulation of lubricating oil (8), whereby means (7) for delivering lubricating oil (8) out of a lubricating oil reservoir (6) deliver lubricating oil (8) to the toothing engagement (9) between the rack (4) and the pinion (3).

摘要： The invention relates to a radially mobile floating bearing (1) for a shaft (2) of a gear (3) of a steering system, with a bushing or an inner ring (4) or a rolling bearing (18), which is supported in a seat (5) of a frame (6) or housing of the gear (3), wherein the inner ring (4) or the bushing or the rolling bearing (18) is held by at least one support element (8) made of material having elastomer properties inserted into a gap (7) between the seat (5) and the inner ring (4), which is designed as pivot bearing (9). In order to provide a radially mobile floating bearing for a shaft of a gear of a steering system, which is low-noise, easily pivotable and highly loadable, it is provided that the pivot bearing (9) cooperates with a damping stop at a tangential distance from the latter (10), which is arranged at a radial distance (a) from the inner ring (4) or the seat (5).

摘要： Disclosed is a device for pressing a rack (1) onto a pinion. Said device comprises a pressure piece (2) and a stop element (3). A spring element (4) that applies at least one of two successive stages of contact pressure, which press the pressure piece (2) against the rack (1), is disposed between the pressure piece (2) and the stop element (3). The pressure piece (2) and the stop element (3) are each provided with mutually aligned contact surfaces (17a, 17b) which are located at a distance from each other in a basic position. At least one of the contact surfaces (17a, 17b) is configured in a springy manner such that the second stage of contact pressure (2) begins as soon as the contact surfaces (17a, 17b) enter in contact with one another.

摘要： The invention relates to a rotary disk valve (1) for power steering systems of motor vehicles, containing a rotary disk (2) which is rotationally fixed to a valve input element (4). The control bush (3) is rotationally fixed to the valve output element (5). The two valve elements are situated in such a way that they can move into each other coaxially, and can turn as far as possible in relation to each other about the path of rotation of a backlash coupling. The rotary disk (2) has outer longitudinal control slots and the control bush (3) inner longitudinal control slots (6, 7). Said longitudinal control slots (6, 7) interact in order to direct a pressure means to and from two working chambers of a servomotor. The rotary disk (2) is connected to the valve output element (5) by a torsion bar (9). Production-related tolerances, which could have undesirable effects on the handling of the vehicle are compensated by a hung connection (10) with zero play.
