Abstract: A two-chamber step bearing with hydraulic damping especially for mounting engines of motor vehicles is presented. It has at least one fluid-filled working chamber and at least one compensating chamber connected to same by a nozzle channel of variable cross section. The cross section of the nozzle channel is changed by means of a first motor-powered actuating drive. The working chamber is provided with a buckling spring, which is integrated in its walls and whose stiffness can be changed by means of a second motor-powered actuating drive. The second motor-powered actuating drive is independent from the first actuating drive. Due to the described design embodiment the two-chamber step bearing can be continuously adapted during the operation of the two-chamber step bearing to both the damping of low-frequency vibrations of large amplitude and the damping of high-frequency vibrations of small amplitude. The bearing is an especially compact and inexpensive design.

Abstract: A shifting device for an automatic transmission of a motor vehicle, in which a selector lever is pivotable within a shift gate around a selection axis located deeper than the said shift gate and is held by spring forces acting at right angles to the longitudinal direction of the shift gate against locking elements. The locking elements are laterally offset in relation to one another and are associated with the shift positions, in the shift positions P, R, N, and D. The selection axis of the selector lever is mounted in a universal joint-like manner in an intermediate part. The intermediate part is mounted pivotably around the selection axis on a housing that is a rigid part of the body, and--in the auxiliary shift position (M) for stepwise, manual shifting in the shift position (D) associated with automatic shifting--the selector lever is pivotable manually in relation to the intermediate part around a drag bearing located higher than the selection axis in the direction of the selection movement.
