Abstract:
The invention relates to a clutch assembly for a motor vehicle, comprising: a disconnect clutch for disconnecting a driveline; a spring element which loads the disconnect clutch into a closed position; a ball ramp unit for loading the disconnect clutch into an open position, wherein the ball ramp unit comprises an outer ring with outer ball tracks, an inner ring with inner ball tracks and a plurality of balls; a drive unit for operating the ball ramp unit; wherein the outer and inner ball tracks are configured to be ramp-like such that a rotation of one of the rings effected by the drive unit results in an axial movement between the rings so that the disconnect clutch is opened; wherein the outer and inner ball tracks extend in the circumferential direction across less than 120° and wherein the outer and inner ball tracks are configured such that a force line, that in a longitudinal section extends through an outer and inner ball contact area, encloses an angle with the rotational axis which is greater than 0° and smaller than 90°.

Claim (Index 32):
A method of controlling a clutch assembly for a driveline of a motor vehicle that comprises:\n a disconnect clutch for disconnecting a driveline, wherein the disconnect clutch comprises at least a first clutch part and a second clutch part; a spring element that loads the disconnect clutch into a closed position in which the torque is transmittable between the first clutch part and the second clutch part; a ball ramp unit for loading the disconnect clutch into an open position, wherein the ball ramp unit comprises an outer ring with a plurality of circumferentially distributed outer ball tracks, an inner ring with a plurality of circumferentially distributed inner ball tracks, and a plurality of balls which are each arranged between an outer ball track and an inner ball track; a drive unit for operating the ball ramp unit, wherein the drive unit is configured to rotatingly drive one of the outer ring and the inner ring around a rotational axis; wherein the outer ball tracks and the inner ball tracks are configured to be ramp-like such that rotatingly driving the rotatingly drivable ring by the drive unit effects a relative axial movement between the outer ring and the inner ring, so that the disconnect clutch is opened; wherein the outer ball tracks and the inner ball tracks extend in the circumferential direction across less than 120\u00b0, and wherein the outer ball tracks and the inner ball tracks are configured such that a force line, that in a longitudinal section extends through an outer and an inner ball contact area, encloses an angle with the rotational axis that is greater than 0\u00b0 and smaller than 90\u00b0,\n wherein one of the outer ring and the inner ring is axially supported on a stationary component and the other one of the outer ring and the inner ring is axially movable by operating the drive unit; \n the method comprising: \n opening the disconnect clutch by operating the drive unit in a first operating direction, wherein the axially movable ring is at least moved into an engagement position; \n braking a driveshaft connected to the second clutch part when the first clutch part and the second clutch part are disconnected from one another by moving the axially movable ring beyond an engagement position away from the axially supported ring, so that the second clutch part is at least indirectly brought into contact with a stationary component; \n deactivating the drive unit, wherein the axially movable ring is held in the engagement position at a distance from the axially supported ring, so that the disconnect clutch remains open; closing the disconnect clutch by operating the drive unit in an opposed second operating direction, wherein the axially movable ring is moved out of the intermediate engagement position and is loaded towards the axially supported ring by the spring.
