20100258399 | Friction clutch - A friction clutch for a drive train, the clutch including a pressure plate rotatably fixed and axially displaceable relative to a housing. A disc spring is provided between the housing and the pressure plate to axially act on the pressure plate. An adjusting device is effective between the housing and the disc spring to compensate for friction lining wear of a clutch plate that interacts with the pressure plate when the clutch is operated in the drive train. The disc spring is pivotable relative to an annular support carried by the housing. An axial force is applied to the disc spring in the direction of the support by springs that include a leaf-spring, a sensor spring, and an additional spring. | 10-14-2010 |
20110056790 | Friction clutch having a wear adjuster - A friction clutch having a wear adjuster that compensates for wear in the form of an incorrect spacing between the pressure plate and the pressing plate as a result of an abrasion of the clutch friction linings. The incorrect spacing between the disk spring and the pressing plate is compensated by a ramp device. The ramp device and the pressing plate are coupled to one another by a positive connection, which, in order to compensate for the incorrect spacing, is temporarily suspended only when the incorrect spacing has been detected by a position sensor. | 03-10-2011 |
20120241275 | WET CLUTCH - A wet clutch including a main clutch, a clutch basket, which is actively connected to a crankshaft, forming an intake part and having a plurality of discs mounted therein so as to be rotatably fixed and axially displaceable, a clutch hub which is connected to a transmission input shaft, forming an output part and having counter-discs that are layered in an alternating manner with the plurality of discs, where the counter-discs are mounted so as to be rotatably fixed and axially displaceable, and a pilot clutch, actuated by means of a lever element, where the pilot clutch is upstream from the main clutch and the pilot clutch and the main clutch are connected to each other by means of a ramp device which is provided, in the circumferential direction, with ramps that are active at least in the direction of traction of the internal combustion engine. | 09-27-2012 |
20120241277 | CLUTCH HAVING A PRE-CLUTCH AND A MAIN CLUTCH - A clutch including a pre-clutch and a main clutch, where the pre-clutch can be brought into an engaged or disengaged state by a clamping means, where the pre-clutch is connected via an effective connection to the main clutch, such that in the disengaged position and engaged position are transmitted to the main clutch, where the pre-clutch is arranged between the main clutch and a connection area for an actuating element of the clamping means, that the clamping means is effectively connected to an outer area by means of a clutch hub of the pre-clutch, that the clamping means is effectively connected in a middle area to a disc of the counter-disc of the pre-clutch, and that the clamping means has a contact area for the actuating element in an inner area. | 09-27-2012 |
20120247914 | CLUTCH DEVICE - The invention relates to a clutch device, for example, a booster clutch device, including a first clutch element and a second clutch element, where a torsion spring device is provided coupling the first clutch element to the second clutch element, the torsion spring device having a multi-stage spring characteristic. | 10-04-2012 |
20130248318 | ADJUSTING DEVICE - The present invention relates to an adjusting device for a friction clutch of a motor vehicle, having a spindle, a spindle nut screwed onto the spindle to carry along an adjusting element to adjust a wear-related incorrect gap between a counter plate and a pressure plate for pressing a clutch plate between the pressure plate and the counter plate, and an essentially frictionally engaged and/or essentially stepless means of swiveling for swiveling the spindle to adjust the wear-related incorrect gap, as well as to a friction clutch having such an adjusting device. | 09-26-2013 |
20130256085 | CLUTCH DEVICE - A clutch device including at least one torque transmission device engageable and/or disengageable in an axial direction by a lever element and forming a friction-locking connection when engaged, at least one wear readjustment device that includes at least one rotatable ramp ring at least temporarily clampable by the lever element and at least one spindle drive rotatably supported to act on the ramp ring and including a spindle shaft, where the wear readjustment device includes at least one infinitely variable freewheel unit to rotate the spindle shaft in the case of a sensed wear condition of the torque transmission device, the infinitely variable freewheel unit including at least one wrap spring or at least one freewheel sleeve. | 10-03-2013 |
20130313061 | CLUTCH HAVING A PRE-CLUTCH AND A MAIN CLUTCH - A clutch having a pre-clutch and a main clutch, where the pre-clutch can be brought to an engaged or a disengaged state by a tensioning means, the pre-clutch being connected to the main clutch by means of an operative connection in such a way that the disengaged position and the engaged position are transmitted to the main clutch, and where the tensioning means is supported on a clutch basket of the main clutch. | 11-28-2013 |
20140033861 | CLUTCH ARRANGEMENT - A clutch arrangement, in particular for use in the drive train of a motor vehicle, including a flywheel which is arranged on the drive side and is coupled via a spring arrangement to a secondary disk and is part, with said secondary disk, of a two-mass flywheel. The secondary disk has at least one centrifugal force pendulum, and a threaded sleeve is screwed with an outer thread into an inner thread of the secondary disk, and a clutch housing is screwed to an inner thread of the threaded sleeve via a fastener. | 02-06-2014 |
20140102846 | WET CLUTCH FOR A MOTORCYCLE - A wet clutch for a motorcycle having an outer basket having a first toothing as the input side of the wet clutch, an inner basket which is coaxial to the outer basket having a second toothing as the output side of the wet clutch, first frictional elements which are torsionally connected to the outer basket, second frictional elements which are torsionally connected to the inner basket, the first and second frictional elements being situated axially alternating between the inner basket and the outer basket, and a clamping element to compress the first and second frictional elements axially in order to produce a torsional connection between the input side and the output side. The inner basket and/or the outer basket can essentially be produced from one or more sheet metal parts. | 04-17-2014 |
20140166424 | COUPLING DEVICE - A coupling device including at least one torque transmitting device, which can be engaged and/or disengaged in the axial direction by a lever element and which is frictionally engaged in the engaged state, and including at least one wear compensation device, which has at least one rotatable ramp ring that can be clamped by the lever element at least temporarily and which has at least one rotatably mounted spindle drive with a spindle shaft, the spindle drive acting on the ramp ring. The wear compensation device has at least two continuously variable free running units which act in different rotational directions, a first free running unit being designed to rotate the spindle shaft when a wear state of the torque transmitting device is sensed and a second free running unit being designed to prevent a reverse rotation of the spindle shaft. | 06-19-2014 |
20140329640 | CLUTCH DEVICE - A clutch device having an actuating device for a drivetrain of a motor vehicle having an internal combustion engine, an electric machine with a stator and a rotor, and a transmission device, where the clutch device is situated in the drivetrain between the internal combustion engine on the one side and the electric machine and the transmission device on the other side, the clutch device and the actuating device being integrated into the rotor of the electric machine, in order to improve the construction and/or the function of the clutch device. | 11-06-2014 |
