摘要： A claw clutch for positively connecting a first rotatable component to a second rotatable component. A claw clutch for motor vehicles having an electric drive train which permits a reliable connection of the claw clutch when tooth-on-tooth positions are released and, at the same time, reduces the number of moving elements on the sliding sleeve. A clutch body, which is arranged on the first rotatable component for conjoint rotation therewith, has a first tooth system and a sliding sleeve, which is arranged on the second rotatable component in a manner which allows conjoint rotation and axial movement, has a second tooth system and is axially movable via a shift fork by an actuator system in order to load a spring element by the actuator system in the case of a tooth-on-tooth position. The spring element to be loaded is arranged outside the second rotatable component equipped with the sliding sleeve.

摘要： A method for controlling an operation of the gear mechanism of a motor vehicle having a freewheel device coupled to an electrical machine and configured to couple the electrical machine rotation speed-dependently to an output of the freewheel device or decouple it therefrom. The gear mechanism depending on a state change signal, starting from a decoupled state of the freewheel device, is operated in a pre-synchronization phase in which the rotation speed of the electrical machine is regulated to a target rotation speed, in particular below an actual rotation speed of the output, and on reaching a nominal rotation speed below the target rotation speed, a coupling phase is implemented in which the target rotation speed is increased and the transition to the coupled state of the freewheel device is performed.

摘要： A dog clutch arrangement for a motor vehicle having a clutch body. The clutch body has first teeth in a first toothing and an axially movable sliding sleeve arrangement with second teeth in a second toothing. The sliding sleeve arrangement has a shift ring and a sleeve with the second toothing, and the shift ring and the sleeve are decoupled over a predetermined path by a decoupling element
