Patent application number | Description | Published |
20090056913 | Heat exchanger and method of manufacturing - The invention relates to a heat exchanger comprising at least one pipe ( | 03-05-2009 |
20090114498 | Clutch unit including a wet clutch - A clutch unit for use in the drive train of a motor vehicle between a drive unit and a transmission including at least one transmission input shaft. The clutch unit includes at least one wet clutch device that is provided with a plurality of clutch elements, in particular clutch discs, that are at least partially wetted by a coolant such as oil. The coolant carries away frictional heat that is generated by slippage between adjacent clutch discs during certain vehicle operating conditions. The heat absorbed by the clutch coolant is cooled by heat transfer from the coolant to a cooler that surrounds the clutch unit. | 05-07-2009 |
20090283344 | DRIVE TRAIN HAVING A WET STARTING CLUTCH FOR HYBRID APPLICATIONS - A starting clutch running in oil is present in the drive train of a motor vehicle which has an internal combustion engine and a starter generator. The rotor of the starter generator is supported on a clutch cover, at least indirectly, and the clutch cover is rotationally fixed to the clutch bell of the transmission. | 11-19-2009 |
20110259698 | HYBRID MODULE FOR A DRIVE TRAIN OF A VEHICLE - A hybrid module for a drive train of a vehicle, including a first disconnect clutch ( | 10-27-2011 |
20110266110 | CLUTCH UNIT COMPRISING A TORSIONAL VIBRATION DAMPER - A clutch unit ( | 11-03-2011 |
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 |
20120043176 | DOUBLE CLUTCH COMPRISING A TORSIONAL VIBRATION DAMPER - A double clutch transmission comprising a wet dual clutch, a dual mass flywheel and a centrifugal force pendulum and an electric motor which is connected to the primary side of the dual mass flywheel. | 02-23-2012 |
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 |
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 |
