| 20080210480 | Drive Train, Pertaining Operating Method and Motor Vehicle - Method is disclosed for operating a drive train having an electric machine and an internal-combustion engine with a supercharger having at least one additional electric machine for the optional drive of a power transmission. An optimal operating point of the at least one additional electric machine is selected as a function of the definable operating point of the internal-combustion engine such that the electric energy flowing during the operation of the at least one additional electric machine at the optimal operating point flows between electric machines without any detouring. | 09-04-2008 |
| 20080245586 | Device and Method for Heating a Crankcase Ventilation System in a Hybrid Vehicle - A device and method for heating a positive crankcase ventilation system in a hybrid vehicle includes a ventilation device, provided on a crankcase, and a supercooling cycle for cooling power electronics for an electric motor of the hybrid vehicle. The ventilation device is heatable by way of the supercooling cycle in order to prevent icing of the ventilation device. | 10-09-2008 |
| 20090124452 | Method for Starting a Piston Engine and Hybrid Drive for Performing the Method - A method is provided for starting a piston engine of a hybrid drive in an electric travel state. The hybrid drive includes at least the piston engine, an electric motor, a transmission, and a clutch situated between the piston engine and the electric motor. A converter lockup clutch, which is switchable into a slip state, is also provided. A slip is set at the converter lockup clutch, and a speed of the electric motor is then increased. The speed and the torque either do not change or only change in a predefined range at the output side of the converter lockup clutch. The clutch is closed to transmit a torque pulse, so that a first top dead center of the piston of the piston engine may be overcome. A predefined slip is then set at the clutch. | 05-14-2009 |

| 20080308354 | Power Divider for Motor Vehicles and Lubrication Thereof - A power divider for motor vehicles includes a housing, a primary shaft and a secondary shaft, wherein a friction clutch having an outer part that is rigidly connected to the primary shaft, and an inner part, derives torque from the primary shaft and delivers the torque to the secondary shaft by means of the inner part and a displacement drive. To ensure a sufficient supply of lubrication oil under all conditions, an oil reservoir, which at least partially surrounds the ramp ring, is fixed in the housing between the coupling and the displacement drive. The base of the oil reservoir comprises at least one opening, which is adjacent to the upper part of the periphery of the ramp ring, and the oil reservoir has at least one guiding device that extends into the centrifugal area of the displacement drive, through which the centrifuged lubrication oil is received in the reservoir. | 12-18-2008 |

| 20100307883 | SEALING DEVICE FOR A DUAL CLUTCH TRANSMISSION OF A MOTOR VEHICLE - A device for sealing a double clutch transmission of a motor vehicle, with a transmission housing, in which are arranged a clutch chamber with clutch oil and a double clutch, a transmission chamber with transmission oil and a double clutch transmission wheel set and two co-axial drive shafts disposed, one inside the other. One drive shaft is an interior central shaft which extends inside the transmission chamber from the end of the second hollow drive shaft. The two drive shafts each have a sealing element to seal the clutch chamber from the transmission chamber. A mounting component is situated inside and fixed to the transmission housing to support two adjacent sealing elements. A first sealing element forms a seal radially on the hollow drive shaft and a second sealing element forms a seal radially on the central drive shaft to provide a reliable seal and offer a simple ventilation and leakage detection. | 12-09-2010 |
