Abstract
A clutch for selectively coupling a motor to a motor vehicle drive train includes a housing, a shift sleeve, an actuating bell arranged to move the shift sleeve, a piston and a stop disc. The housing includes a first pressure chamber and a second pressure chamber. The piston is connected to the actuating bell and arranged in a pressure-dependent axially movable manner between the first pressure chamber and the second pressure chamber. The stop disc is arranged in the first pressure chamber or in the second pressure chamber for limiting axial mobility of the piston.
Claims17
A clutch for coupling a motor to, and decoupling said motor from, a motor vehicle drive train, having a piston which is arranged in a pressure-dependent axially movable manner between two pressure chambers in a housing, wherein the piston is connected to an actuating bell which is designed for contacting or moving a shift sleeve, wherein:
- a stop disc is arranged in a one of the two pressure chambers, which limits an axial mobility of the piston;
- and
- a plurality of axial projections distributed over a circumference protrude from an end face of the stop disc.
A clutch for selectively coupling a motor to a motor vehicle drive train, comprising:
- a housing comprising a first pressure chamber and a second pressure chamber;
- a shift sleeve;
- an actuating bell arranged to move the shift sleeve;
- a piston connected to the actuating bell and arranged in a pressure-dependent axially movable manner between the first pressure chamber and the second pressure chamber;
- and
- a stop disc arranged in the first pressure chamber or in the second pressure chamber for limiting axial mobility of the piston, the stop disc comprising:
- an axial projection arranged to extend through the first pressure chamber or the second pressure chamber and contact the piston;
- and
- an end face, wherein the axial projection is one of a plurality of circumferentially distributed axial projections projecting from the end face.
