  • Patent number: 7066077
    Abstract: A device for supporting and for at least contributing to the activation of an actuating element. An outer thin-walled bearing ring defines a pressure space to which pressure is applied. The outer thin-walled bearing ring at least partially bounds a circumference of the pressure space. A piston supports the actuating element and moves longitudinally within the pressure space with respect to the outer thin-walled bearing ring. Roller bodies configured to roll on the outer thin-walled bearing ring for supporting the actuating element.
    Type: Grant

  • Patent number: 6402382
    Abstract: The inner casing (1) of a rollerbearing permitting longitudinal movement over a limited travel path and designed for longitudinally displaceable mounting or guiding of a rod (8) is provided with an inwardly directed projection (9) on each of at least two opposing lateral surfaces (1a, 1c).

  • Patent number: 6286384
    Abstract: A shift control apparatus for use in a change-speed gearbox of motor vehicles includes a housing, a selector shaft axially slidably and rotatably supported in the housing and operatively connected to a gear selector lever for axial displacement of the selector shaft to realize a preselection of a shifting lane and rotation of the selector for shift into a selected gear, a shifter finger secured to the selector shaft and engaging slidable shifter forks or shifter bars, and a restraining mechanism for preventing a misshift between a reverse gear and a forward gear positioned in a same shifting lane. The restraining mechanism includes a transmission element mounted in fixed rotative engagement to the selector shaft and having a flanged edge, and a restraining member rotatable and axially moveable in parallel relationship to the selector shaft. The restraining member has a locking surface forming a deflector ramp for support of the flanged edge of the transmission element, thereby effecting a deflection, i.e.

  • Patent number: 5634375
    Abstract: A locking device for a positional fixing of a displaceable adjusting element for a selector shaft of a mechanical gear transmission of a motor vehicle comprising an outer housing (2) and, displaceably guided therein, a locking pin (8) loaded at one end by a compression spring (14) which is supported on a bottom (15) and causes a stroke movement of the locking pin (8), the selector shaft comprising a recess which is engaged by a spherical locking element (11) retained in an end of the locking pin (8) facing away from the compression spring, the locking device further comprising an electric switching element (25) which can be activated by an actuating element arranged on the locking pin (8), characterized in that the actuating element is an compensation element (16a to 16d).
