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.
Claims8
A device for supporting and for at least contributing to the activation of an actuating element, the device comprising:
- a housing of a change speed gear mechanism;
- an actuating element having an end and being longitudinally movably mounted with respect to the housing of the change speed gear mechanism;
- an outer thin-walled bearing ring supported in the housing of the change speed gear mechanism and defining and at least partially bounding a circumference in which the actuating element is supported;
- a pressure space to which pressure may be applied, the pressure space is at the end of the actuating element;
- a piston for engaging the end of the actuating element and configured to move longitudinally within the pressure space with respect to the outer thin-walled bearing ring and to which pressure is applied by a medium in the pressure space;
- and
- roller bodies positioned to roll on the outer thin-walled bearing ring and for supporting the actuating element.
A device for supporting and for at least contributing to the activation of an actuating element, the device comprising:
- an actuating element having an end and an outer circumference;
- an outer thin-walled bearing ring defining and at least partially bounding a circumference in which the actuating element is supported;
- a pressure space to which pressure may be applied, the pressure space is at the end of the actuating element;
- a piston for engaging the end of the actuating element and configured to move longitudinally within the pressure space with respect to the outer thin-walled bearing ring and to which pressure is applied by a medium in the pressure space;
- roller bodies positioned to roll on the outer thin-walled bearing ring and for supporting the actuating element;
- and
- an inner bearing ring at least partially engaging the actuating element at the outer circumference thereof,
- the inner bearing ring elastically pre-stressing the roller bodies radially against the outer thin-walled bearing ring without play, the roller bodies supporting the inner bearing ring on the outer thin-walled bearing ring.

- and
- roller bodies positioned to roll on the outer thin-walled bearing ring and for supporting the actuating element;
- wherein the pressure space has a longitudinal side, the outer thin-walled bearing ring is cylindrical with a cup-shape including a sidewall and a base, the sidewall of the outer thin-walled bearing ring radially bounds the circumference of the pressure space, and the base of the thin-walled bearing ring bounds an outward longitudinal side of the pressure space.
