Patent application numberDescriptionPublished
20080230342Torque transmission device - A torque transmitting device in a drive train of a motor vehicle to transmit torque between an internal combustion engine having a drive shaft and a transmission having coaxial input shafts. The transmission input shafts are each non-rotatably connected with a respective clutch disc having friction linings. An intermediate pressure plate is positioned between the friction linings of the clutch discs and is non-rotatably connected to the engine drive shaft. The friction linings of the clutch discs are between the intermediate pressure plate and respective axially movable clutch pressure plates that are actuated by an actuation device. To provide support for the double clutch unit the intermediate pressure plate is radially mounted on one of the two transmission input shafts.09-25-2008
20090103846Decoupling device for mounting a shaft on a base and radial ondular washer - A decoupling device for the bearing arrangement of a shaft carried in a housing, in particular a shaft of a belt-driven conical-pulley transmission with a chain that functions as the belt. The decoupling device includes an outer bearing ring configured with a circularly cylindrical outer surface and within which the shaft is mounted, and an inner surface of a housing that encloses the bearing ring outer surface. At least one radial ondular washer is arranged between the bearing ring outer surface and the housing inner surface, which allows a limited relative radial movement between the housing inner surface and the bearing ring outer surface by elastic deformation of the washer.04-23-2009
20090145679Method for controlling the operation of a generator in a vehicle power train, and a vehicle power train - A method for controlling the operation of a generator connected to an electrical energy storage unit in a vehicle power train. An engine is connected to a drive shaft of the vehicle through a transmission and with an interrupting device with which the transmission of torque from the engine to the drive shaft is interruptible. When the transmission of torque between the engine and the drive shaft is interrupted the generator is driven from the drive shaft.06-11-2009
20090205923Clutch unit - A clutch unit including a torsional vibration damper and having at least friction clutch, but can have two friction clutches combined into a twin clutch. The torsional vibration damper includes an input component that extends axially over the at least one friction clutch at the outer circumference of the friction clutch, so that a counterpressure plate of the at least one friction clutch is disposed axially between the drive engine and energy accumulators carried by the torsional vibration damper. Thus, the clutch unit has a smaller axial extent and can be accommodated in limited installation spaces.08-20-2009
20110233021Torque transmission device - A torque transmitting device in a drive train of a motor vehicle to transmit torque between an internal combustion engine having a drive shaft and a transmission having coaxial input shafts. The transmission input shafts are each non-rotatably connected with a respective clutch disc having friction linings. An intermediate pressure plate is positioned between the friction linings of the clutch discs and is non-rotatably connected to the engine drive shaft. The friction linings of the clutch discs are between the intermediate pressure plate and respective axially movable clutch pressure plates that are actuated by an actuation device. To provide support for the double clutch unit the intermediate pressure plate is radially mounted on one of the two transmission input shafts.09-29-2011
20110278124Clamping element freewheel - A clamping element freewheel including an inner ring and an outer ring that can be rotated relative to the inner ring in at least one rotational direction. A cage for clamping elements is between the inner ring and the outer ring, with a plurality of clamping elements. The clamping elements are pivotable between a clamping position, in which they prevent relative rotation between the inner and outer rings, and a release position, in which they enable relative rotation between the inner and outer rings. A clamping element preload is provided to preload the clamping element radially inwardly and in the clamping position direction. The clamping element preloading is provided by springs that are configured separately for each clamping element.11-17-2011
20120190492VEHICLE DRIVE - A twin engine having a powershift transmission in front longitudinal arrangement.07-26-2012
20130014727INTERNAL COMBUSTION ENGINE - The invention relates to an internal combustion engine comprising a plurality of subunits which each comprise a crankshaft part, at least one piston being accommodated on a crank of each crankshaft part by means of a connecting rod, wherein at least one first subunit is permanently operated while the internal combustion engine is operating, and at least one additional subunit can be switched off. To switch off a subunit and to disconnect the crankshaft parts from each other, the crankshaft parts of at least one first subunit and an adjacent second subunit that can be switched off are connected to each other in a rotationally locked manner and can move relative to each other with respect to the rotational axes thereof in such a way that a rotational motion applied to the crankshaft part of the second subunit by the crankshaft part of the first subunit is substantially suspended.01-17-2013
20150028658ACTUATING DEVICE FOR A TORQUE TRANSMISSION DEVICE - The invention relates to an actuator device for torque transmission equipment such as a clutch, e.g. a friction clutch or dog clutch, or a brake, comprising at least two electric motors, wherein the rotors of the electric motors are kinematically coupled together via a summation gear, and the summation gear has an output side which is coupled to an actuator of the torque transmission equipment in such a way that a state of the actuator can be set as a function of a relative rotation between the two rotors.01-29-2015
