Abstract
The invention relates to a clutch (1) for coupling and uncoupling an engine to and from a motor vehicle drive train, said clutch comprising a piston (2) which is positioned in a housing (3) so as to be axially displaceable between two pressure chambers (6, 7) as a result of pressure, the piston (2) being connected to an actuation bell (8) which is designed to contact/move a sliding sleeve (9), an end stop disc (22) being provided which is elastic in the axial direction in order limit the axial displaceability of the sliding sleeve (9).
Claims18
A clutch for coupling and uncoupling a motor to and from a motor vehicle drive train, having a piston which is arranged in a housing between two pressure chambers so as to be axially displaceable due to pressure, wherein the piston is connected to an actuating cap which is arranged for contacting or moving a sliding sleeve, wherein an end stop disc which is designed to be elastic in the axial direction is provided in order to limit the axial displaceability of the sliding sleeve, and wherein the end stop disc has an S-shape or double S-shape in a longitudinal section along the axis of rotation of the clutch.
A clutch for selectively coupling a motor and a motor vehicle drive train, comprising:
- an axis of rotation;
- a housing comprising two pressure chambers;
- a sliding sleeve;
- an actuating cap arranged for moving the sliding sleeve;
- a piston:
- arranged in the housing between the two pressure chambers;
- axially displaceable due to pressure;
- and
- connected to the actuating cap;
- and
- an end stop disc, axially elastic and arranged to limit axial displacement of the sliding sleeve, wherein the end stop disc comprises an S-shape or a double s-shape in a longitudinal section taken along the axis of rotation.
