A clutch device includes a wet-running multiple disc clutch that has a first multiple disc carrier, a second multiple disc carrier, and a multiple disc pack assigned to the first and second multiple disc carrier. The clutch device further includes a first power transmission element on a first axial side of a wall facing away from the multiple disc pack, and a second power transmission element on a second axial side of the wall facing the multiple disc pack for applying an operating power to the multiple disc pack. The second power transmission element has an application section and operating fingers that extend through recesses in the wall to interact with the first power transmission element on the first axial side. The application section protrudes inward in the radial direction over the operating fingers.

Clutch device

The present invention relates to a torque transmission device () comprising a planetary gear train (), which has a rotatable component (), a stationary housing (), and a clutch device () for selective coupling of the component () with the stationary housing (). The clutch device () has a friction-locking first clutch () and a positive-locking second clutch (), wherein the component () may be coupled to the stationary housing () via the first clutch () before a coupling by means of the second clutch ().

Torque transmission device

The present invention relates to a freewheel () comprising an inner ring (), an outer ring (), a clamping gap () between the inner ring () and the outer ring (), a side wall () for lateral limitation of the clamping gap () and at least one clamping element () in the clamping gap () which is biased by means of a spring element (), wherein the spring element () is supported or supportable on one side on the clamping element () and on the other side on a support projection (), which is formed by a supporting tongue () bent out of the side wall () and projecting into the clamping gap (). In addition, the present invention relates to a method for producing such a freewheel ().

Freewheel and method for producing such a freewheel

The present invention relates to a freewheel comprising an outer ring, an inner ring, and at least one clamping element which is between the outer ring and the inner ring, which is moveable from a clamping position into a release position along a race on the outer ring in a first circumferential direction relative to the outer ring, wherein the race has a clamping section, and a release section following the clamping section in the first circumferential direction on which the clamping element is supportable. A first tangent through at least one support point on the clamping section defines a first inner angle, which is greater than 180&#xb0;, with a second tangent through at least one support point on the release section. In addition, the present invention relates to a freewheel arrangement for a motor vehicle comprising such a freewheel.

Freewheel and freewheel arrangement comprising such a freewheel

Disclosed is a freewheel () comprising a first race (), a second race (), a clamping gap () designed between the first and second race (), at least one clamping element () in the clamping gap (), and biasing feature () for biasing the clamping element () into a clamping position within the clamping gap (), wherein the biasing feature () have an accordion spring (), which is supported directly or indirectly on the first race () and which comprises corrugation peaks () lying radially outward, corrugation troughs () lying radially inward, and a support leg () for direct or indirect support on the clamping element (). In addition, disclosed is a freewheel arrangement () comprising such a freewheel ().

A number of variations may include a clutch apparatus having at least one clutch and having an actuating device for actuating the clutch, the actuating device being movable from an opening position, in which the clutch is open, into a closing position, in which the clutch is closed. The actuating device can be locked with form-fit action in the closing position or opening position.

Clutch apparatus with lockable actuating device

The present invention relates to a piston-cylinder arrangement () for the operating device of a clutch, having a cylinder (), a piston () which is arranged in the cylinder () and can be displaced in the axial direction (), and at least one locking element () which is associated with the piston (), wherein the piston () can be displaced from a first position into a second position in which the locking element () can be moved from a released position into a locked position in which the piston () is locked in the second position via the locking element () in a positively locking manner. According to the invention, the piston () can be displaced by means of a locking piston (), which in the released position of the locking element () is connected via the locking element () to the piston () in a positively locking manner in the axial direction () and in the second position of the piston (), with displacement of the locking element () from the released position into the locked position relative to the piston (), can be displaced in the axial direction () from an initial position into a locked position.
