摘要： An electromagnetic control mechanism for a switching element is described herein, which can be switched to an open operating state and to a closed operating state by means of an electromagnet and an actuating unit that acts counter to the actuation force of the electromagnet. The electromagnet has a dedicated mechanism for dampening the actuation movement of an anchor of the electromagnet toward a section of the coil, by means of which the actuation speed of the anchor can be reduced after a distance between a section of the anchor facing the coil and the section of the coil becomes shorter than a predefined distance. The mechanism for dampening comprises at least one component connected to the coil, which becomes functionally connected to the anchor after the distance becomes shorter than the defined distance, wherein, as the displacement of the anchor increases, liquid can be discharged from a chamber bordered by the component and the anchor via a throttle mechanism to an extent that reduces the actuation speed of the anchor.

摘要： An electric drive axle of a vehicle with a parking lock and with at least one electric drive with a drive gear of a drive shaft. The drive gear is coupled via at least one intermediate gear of an intermediate shaft to an output gear of a differential gear unit for driving at least one output shaft. For decoupling the electric drive, at least one claw shift element is associated with the drive shaft and/or with the intermediate shaft in such a way that the claw shift element is arranged upstream of the parking lock in power flow direction from electric drive to differential gear unit.

摘要： An operating device may have a moving operating element, a housing a magnetorheological elastomer, and a coil. An end of the operating element may be supported in the housing. The magnetorheological elastomer may result in a first operating characteristic for operating the operating element in a resting state and a second operating characteristic for the operation in an activated state. The coil may generate a magnetic field that transfers the magnetorheological elastomer between the resting state and the activated state.

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 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. The shift ring and the sleeve at least partially overlap in axial direction and are arranged to be axially displaceable relative to one another. The shift ring and the sleeve enclose an intermediate space, a pneumatic damping which damps the movement of the sleeve and the shift ring relative to one another being formed with the intermediate space.
