Axial adjustment device and actuation arrangement comprising such an axial adjustment device

An actuation arrangement of a clutch unit and a parking lock mechanism, comprising:

• the clutch unit,
• the parking lock mechanism,
• an actuator, and
• an axial adjustment device, the axial adjustment device comprising:
• a first disk which is rotatable and axially displaceable both in a first circumferential direction and in a second circumferential direction, namely a circumferential direction counter to the first circumferential direction, and a second disk which is locked against rotation in the first circumferential direction and is rotatable in the second circumferential direction, wherein the second disk has an activating element on its end side facing away from the first disk, and wherein the first disk and the second disk each have, on their mutually facing end surfaces, at least three identically formed depressions which lie opposite one another in each case in pairs and thus form at least three pairs of depressions, wherein a rolling element is arranged in each of the pairs of depressions, wherein the depressions each have a slope in the first circumferential direction from a lower dead center towards an upper dead center, wherein the pairs of depressions each interact via the rolling elements in such a manner that, when the first disk is rotated in a first circumferential direction (I), the rolling elements run from the lower dead center in the direction of the upper dead center, and therefore the first disk is rotated and displaced axially with respect to the second disk, and that, when the first disk is rotated in the second circumferential direction, the rolling elements run into the lower dead center of the depressions, and therefore the first disk and the second disk are rotated in the second circumferential direction,
• wherein the first disk of the axial adjustment device can be activated via the actuator in the first circumferential direction and in the second circumferential direction, and wherein the actuation arrangement is configured in such a manner that, when the first disk is activated in the first circumferential direction, the clutch unit is actuated into an engagement position, and, when the first disk is activated in the second circumferential direction, the clutch unit is actuated into a disengagement position and the parking lock mechanism is activated.

An actuation arrangement comprising:

• an actuator;
• an axial adjustment device having a first disk and a second disk;
• a clutch unit actuated and engaged by rotation of the first disk in a first circumferential direction and disengaged by rotation of the first disk and the second disk in a second circumferential direction that is opposite the first circumferential direction;
• a parking lock mechanism actuated by rotation of the first disk and the second disk in the second circumferential direction;
• wherein the first disk is rotatable and axially displaceable in both the first and second circumferential directions;
• wherein the second disk is locked against rotation in the first circumferential direction and is rotatable in the second circumferential direction;
• wherein the second disk has an activating element on its end side facing away from the first disk;
• and
• wherein the first disk and the second disk each have, on mutually facing end surfaces thereof, at least three depressions that lie opposite one another in each case in pairs and forming at least three pairs of depressions;
• wherein a rolling element is arranged in each of the pairs of depressions;
• wherein the depressions each have a slope in the first circumferential direction from a lower dead center towards an upper dead center;
• wherein the pairs of depressions each interact via the rolling elements in such a manner that, when the first disk is rotated in the first circumferential direction, the rolling elements run from the lower dead center in the direction of the upper dead center, and therefore the first disk is rotated and displaced axially with respect to the second disk, and that, when the first disk is rotated in the second circumferential direction, the rolling elements run into the lower dead center of the depressions, and therefore the first disk and the second disk are rotated in the second circumferential direction.
