20110114435 | DUAL CLUTCH - A dual clutch which has two friction clutches, a central pressure-exerting plate and two pressure plates which are axially movable relative to the pressure-exerting plate with the interposition of the friction linings of two clutch disks, which each mesh with one gearbox input shaft, of actuating devices. The dual clutch is held at the drive-input side and is supported at the gearbox side by an actuating system, which is rotatably held on the clutch housing, for actuating the pressure plates. | 05-19-2011 |
20110114436 | DUAL CLUTCH - A dual clutch which has two friction clutches, which have a central pressure-exerting plate and two pressure plates which are axially movable relative to the pressure-exerting plate with the interposition of the friction linings of two clutch disks, which each mesh with a gearbox input shaft of actuating devices. The pressure plates are acted on by transmission elements by the actuating devices directly without a lever action. Furthermore, for the cooling and lubrication of the actuating bearings between the actuating devices and the transmission elements, an annular chamber can be formed which has an increased fluid volume. | 05-19-2011 |
20110114437 | DOUBLE CLUTCH - A double clutch which has two friction clutches, a central pressure-exerting plate and two pressure plates that are axially movable relative to the pressure-exerting plate with the interposition of friction linings of two clutch disks, which mesh with each transmission input shaft, of actuating devices. Here, the pressure plates are acted on by transmission elements by the actuating devices directly without a lever action. Furthermore, for cooling and lubrication of actuating devices and transmission elements, an annular chamber with an increase in fluid volume can be formed. | 05-19-2011 |
20110132712 | DUAL CLUTCH - A dual clutch which has two friction clutches, a central pressure-exerting plate and two pressure plates which are axially movable relative to the pressure-exerting plate with the interposition of the friction linings of two clutch disks, which each mesh with in-each case one gearbox input shaft, of actuating devices. The dual clutch is held at the drive-input side, with the dual clutch being supported at the gearbox side by an actuating system, which holds the two actuating devices, for actuating the pressure plates, and with the actuating system being rotatably held on the clutch housing. | 06-09-2011 |
20110272233 | CLUTCH UNIT - A clutch unit, which has at least one wet clutch that is arranged in a housing, which is driven by a drive unit. The clutch is effectively connected to an input part. To simultaneously associate a torsional vibration damper, e.g. a centrifugal pendulum, with the input part, a support disk of the torsional vibration damper is connected to the input part so that no or only minor vibrations are generated, allowing the frequency of the torsional vibration damper to be sufficiently adjusted. For this purpose, at least one plate support is connected to a single support disk which is fixedly mounted on the clutch hub and is thus made rigid. Preferably, the plate support further reduces vibration tolerance. | 11-10-2011 |
20110290610 | MULTIPLE CLUTCH DEVICE - A multiple clutch device which includes a drive unit, a downstream transmission connected to a drive shaft of the drive unit and accommodated in a clutch bell that does not co-rotate with the drive shaft, two wet multi-plate clutches, which include a plate support at the input and output end and plates alternating axially, and an actuation mechanism. A housing of the actuation mechanism is supported on the clutch bell, and the plate support at the input end of at least one of the multi-plate clutches is connected to the housing by a supporting metal sheet or a supporting pot and a footstep bearing such that a flow of an actuation force generated by the actuation mechanism is redirected to the housing of the actuation mechanism via the supporting metal sheet or the supporting pot and the footstep bearing, creating a closed force flow within the device. | 12-01-2011 |
20120085615 | DOUBLE CLUTCH - A double clutch for a double clutch transmission in the drive train of a motor vehicle, with single clutches that are arranged behind each other in the axial dimension and actuated hydraulically, including a single clutch arranged on the drive side, a single clutch arranged on the gear side, a driven clutch housing and two piston-cylinder units. The first of the two single clutches connects the clutch housing to the first transmission input shaft and the second single clutch connects the clutch housing to a second transmission input shaft, wherein both connections can be switched. The clutch housing is connected on the drive side to a drive shaft and on the gear side to input disk carriers. | 04-12-2012 |
20120267211 | OUTER PLATE CARRIER - An outer plate carrier, including a cup-shaped embodied carrier plate ( | 10-25-2012 |
20130025994 | DUAL CLUTCH - A dual clutch for coupling an engine-side input shaft with a first transmission-side and/or a second transmission-side output shaft. A first dutch has a first pressure plate, which is axially mobile relative to a first counter plate, for coupling with a first dutch disk connected to the first output shaft. A second dutch has a second pressure plate, which is axially mobile relative to a second counter plate, for coupling with a dutch disk connected to the second output shaft. A dutch cover is connected to the first and second counter plates. An actuator displaces the first and/or the second pressure plate. The actuator is radially supported on the input side on the input shaft by the clutch cover and a torsional vibration damper, which is connected to the clutch cover and is radially mounted on the output side on one of the output shafts and/or on a transmission housing. | 01-31-2013 |
20130220762 | DUAL-CLUTCH TRANSMISSION - A dual-clutch transmission with individual clutches, which are axially arranged one behind the other and are hydraulically actuated, with one drive-side individual clutch, one gearbox-side individual clutch, one drive-side clutch housing and two cylinder/piston pairs, whereby the first of the individual clutches connects by switch the clutch housing with one of the first gearbox input shafts and the second of the individual clutches connects by switch the clutch housing with one of the second gearbox input shafts, whereby the clutch housing is connected drive-side with a drive shaft and gearbox-side with internally arranged input lamellae supports relating to the single clutches and torque conducted to the dual-clutch transmission via the clutch housing can be conducted to both individual clutches, whereby the clutch housing supports an actuating force from the gearbox-side single clutch and a second support area supports the actuating force from the drive side clutch is provided. | 08-29-2013 |
