| 192700251 | With adjustable means to move clutch-element axially (e.g., to compensate for wear) | 24 |
| 20080308379 | Clutch unit - A clutch unit having at least one friction clutch including a pressure disk joined to a housing in a rotationally fixed but axially displaceable manner. A lever system that can pivot axially is arranged between the housing and the pressure disk and can be impinged upon by an actuation device to engage the clutch. An adjusting device that at least partially compensates wear and tear of the friction lining of the clutch engages between the lever system and the housing. The lever system is axially supported on the housing by a rotatable adjusting ring and can be impinged upon in an axial manner in the direction of the adjusting ring by spring elements to produce an axial supporting force that is opposite to the clutch closing pressure applied to the lever system. A force-path characteristic is produced that reduces at least in the working area, wherein the spring elements are deformed for the at least partial wear and tear compensation. | 12-18-2008 |
| 20090229940 | Device for actuating a friction clutch with automatic adjustment - A device for actuating a friction clutch with automatic adjustment. An actuating movement for engaging and disengaging the clutch is transmitted to a pressing component. The adjusting device includes a sensing component that is biased in the direction of an adjusting movement and compensates for sensing play that occurs as a result of wear when the clutch is engaged, and that compensates for play that occurs when the clutch is disengaged after compensation of the sensing play in the movement transmission between the actuating component and the transmission component. When the clutch is engaged and wear is present, the sensing component moves out of contact against a spring component which, when the clutch is engaged and wear is present, comes into contact against a stop before the fully engaged state of the clutch is reached. | 09-17-2009 |
