Abstract: A method for operating a dual-clutch transmission includes, to resolve a respective tooth-on-tooth position between a toothing of a sliding sleeve and a toothing of a gear wheel during an engaging operation for the respective gear, a relative rotation between the toothing of the sliding sleeve and the toothing of the gear wheel is effected by a twisting torque which acts on the respective gear where the twisting torque is a same size for all of the plurality of gears.

Abstract: In an electric motor having a housing and a rotor for installation in a drive train, the housing includes centering elements which retain the rotor centered in the housing for facilitating mounting of the motor to the drive train, the centering elements being movable out of their centering position during assembly and being retained out of contact with the rotor as long as the motor is installed but being released to assume their centering position whenever the motor is removed from the drive train.

Abstract: A method for changing gear in an automated change-speed gearbox of a motor vehicle with an automated clutch arranged between an engine and the change-speed gearbox includes engaging the clutch up to a slip limit during a downshift from an original gear to a target gear to increase the rotational speed of an input shaft of the change-speed gearbox.

Abstract: An automated non-synchronised gear-change transmission for a motor vehicle includes a transmission input shaft and a pressure-oil lubrication device. The pressure-oil lubrication device includes a pump driven at least indirectly by the transmission input shaft, and a cross-section modification device disposed on a downstream side of the pump. The cross-section modification device is configured to modify a flow cross section on the downstream side of the pump.

Abstract: In a method for controlling a drive line of a vehicle, in which a power-shift clutch is engaged for torque transmission while driving, the point of engagement of a power-shift clutch that is disengaged in parallel is determined by a nonsteady-state engagement operation.

Abstract: A toothed gear transmission is described, in which an input shaft is connected to a differential by a first and a second partial transmission, which are disposed parallel to each other in the power flow and which both have a frictionally engaged load shifting clutch and an intermediate shaft. The elements are disposed concentrically to each other and coaxially to the input shaft, and each intermediate shaft can be effectively connected to the input shaft through the load shifting clutch. At least one toothed gear for each intermediate shaft is provided, of which at least one can be effectively connected to a first driven shaft disposed parallel to the intermediate shafts, which directly or indirectly outputs to the differential gear.
