A rotor carrier for an electric machine having a sleeve-shaped receiving region and at least one flange-like carrier region connected to a hub or shaft. The receiving region has on its outer circumferential surface at least one driving groove extending in axial direction, and a plurality of radial oil bore holes are provided in the receiving region so as to be distributed over the circumference. An encoder wheel having a nonmagnetic material is provided at an axial end of the rotor carrier, and in that the encoder wheel protrudes over the receiving region in radial direction to serve as an axial limit for a rotor lamination stack.

A torsional vibration damping arrangement, in particular mass damper subassembly, having a carrier which can be driven in rotation and a damper mass rotatably deflectable with respect to the carrier against the restoring action of a substantially radially extending damper spring. The damper spring is fixedly clamped in the damper mass and is supported or supportable with respect to the carrier for transmitting circumferential force. The damper spring is clamped between clamping elements arranged at both sides of the damper spring in circumferential direction.

A torque transmission assembly includes two structural component parts for coupled engagement to one another so as to rotate together around an axis of rotation, a first of these structural component parts has an inner circumferential toothing and a second of these structural component parts has an outer circumferential toothing for a rotary coupling engagement with the inner circumferential toothing. The teeth in one toothing of an inner circumferential toothing and outer circumferential toothing are bounded by end faces in a first axial end area of the one toothing. The one toothing has at least one tooth with an end face which is extended forward axially relative to the end faces of the other teeth of the one toothing, and the end face of at least one tooth of the one toothing with the end face which is extended forward axially forms a circumferentially deflecting end face for the other toothing.

Torque transmission assembly, particularly for the drivetrain of a vehicle

A hydrodynamic clutch device used to establish and to release a working connection between a drive and a takeoff is disclosed. The device includes a housing capable of rotating around an axis of rotation, the housing containing a torus space, which forms a torus volume (TV) with a pump wheel and a turbine wheel, and a clutch space, which forms the boundaries of the clutch volume (CV) and which encloses a mechanical transmission circuit including a bridging clutch designed with a torsional vibration clamper. During the course of the minimum resting phase of the housing, the fluid which is distributed throughout the housing during the operating state decreases from a total volume comprising at least the torus volume (TV) and the clutch volume (CV) to a resting volume (RV), which is located at least essentially underneath the axis of rotation as a result of the force of gravity. A volume reduction arrangement is provided to the housing to reduce the clutch volume (CV) versus the resting volume (RV).

Hydrodynamic clutch arrangement

A torsional vibration damper in a gearbox housing has an input part connected to a drive and acts on a first damping unit and an intermediate part which acts as the output of the first damping unit and as the input of a second damping unit. The torsional vibration damper further has an output part which is in working connection with the second damping unit and which is designed to accept a takeoff. Takeoff-side drive elements of the intermediate part, the second damping unit, and the takeoff are mounted in a torque-transmitting space of a clutch device, which space is provided with at least one inlet and at least one outlet. A sealing wall separates the torque-transmitting space from a damping space including the first damping unit.

Torsional vibration damper

An actuating drive for transmitting drive torque to a power takeoff, comprising a drive unit; a braking device comprising a cylindrical surface; and a wrap spring having a plurality of turns which are concentric to the cylindrical surface, a pair of ends, a first actuating area on one of the ends, and a second actuating area on one of the ends. When the drive unit exerts a drive torque in a first direction, the first actuating area is nonrotatably connected to the drive unit, the turns undergo a diameter change away from the cylindrical surface, and the second actuating area is nonrotatably connected to the power takeoff for transmitting drive torque. When the drive torque is interrupted, the turns undergo a diameter change toward the cylindrical surface and frictionally engage the cylindrical surface to block transmission of restoring torque from the power takeoff to the drive unit.

Actuating drive with a wrap spring arrangement

A friction clutch with a mechanically-operated disengagement device that includes two elements that can be turned relative to one another, which are arranged concentric to the rotational axis and are supported on the clutch housing, on the one hand, and on the operating elements of the friction clutch on the other. These two elements are connected to the clutch pedal with a cable, on the one hand, and with a sheath, on the other.
