Abstract: The present invention relates to a multi-disc clutch for the transfer of torque between a first clutch part and a second clutch part, having at least one first and at least one second disc that engage on another and that are movable parallel to a rotational axis of the multi-disc clutch, and having a reset device for the receiprocal ventilation of adjacent discs. The first clutch part is connected in a rotationally secure fashion to the first disc and the second clutch part is connected in a rotationally secure fashion to the second disc. The reset device has at least two reset elements that are disposed eccentrically relative to the rotational axis and distributed in the circumferential direction.

Abstract: A torque transmission arrangement including a primary shaft, a friction clutch, a housing in which the primary shaft is rotatably supported by a roller element bearing including an inner ring and an outer ring. An actuator is disposed in the housing between the friction clutch and the roller element bearing for actuating the friction clutch. The actuator comprises a fixed support element, an adjusting element axially offset from the support element and displaceable for engaging the friction clutch, and an actuating mechanism designed for displacing the adjusting element relative to the support element in an axial adjusting direction away from the roller element bearing. The roller element bearing is designed as a tapered roller bearing, and the support element is operationally connected to the tapered roller bearing.

Abstract: A device for setting the torque transferred from a primary shaft to a secondary shaft by a friction clutch comprises a supporting element and an axially displaceable adjusting element which is rotatable with respect to the supporting element and which is operatively connected to the friction clutch for the actuation of the latter, the adjusting element comprising a toothed ring, and the supporting element and adjusting element cooperating via coupling elements in such a way that a rotation of the adjusting element in relation to the supporting element brings about an axial displacement of the adjusting element in relation to the supporting element. The device comprises a linearly displaceable rack element which is in engagement with the toothed ring of the adjusting element, and an electrically activatable linear drive arrangement for the controlled displacement of the rack element.

Abstract: A torque transfer mechanism is provided for controlling the magnitude of a clutch engagement force exerted on a multi-plate clutch assembly that is operably disposed between a first rotary and a second rotary member. The torque transfer mechanism includes a power-operated face gear clutch actuator for generating and applying a clutch engagement force on the clutch assembly.

Abstract: The drive train of an all-wheel drive vehicle comprises a transfer case that is connected to the motor block, a driven front axle, a driven rear axle, drive shafts and a control device. To vary the torque distribution between the axles from 0 to 100% the transfer case has a drive-through shaft that has a drive connection both with the motor block and the drive shaft that leads to the rear axle. The drive-through shaft includes a drive connection with the drive shaft that leads to the front axle by a first friction clutch that determines the torque applied to the front axle. The rear axle is equipped with an additional adjustable drive unit comprising a second friction clutch, which is used to control the torque applied to the rear axle.
