Abstract
A coupling arrangement for a drive train of a motor vehicle includes at least one clutch arranged on a rotating shaft in order to couple the rotating shaft selectively with a drive element of the drive train, and at least one activation device to activate the clutch. The activation device is adapted to bring an engagement segment selectively into engagement with a threaded segment rotating with the shaft in order to cause a relative movement of the engagement segment and the threaded segment along the axis of the rotating shaft and thus activate the clutch in the axial direction.
Claims19
A coupling arrangement for a drive train of a motor vehicle, the coupling arrangement comprising:
- a shaft configured for rotation;
- a clutch arranged on the shaft and configured to couple the rotating shaft selectively with a drive element of the drive train;
- an activation device configured to open the clutch, wherein the activation device is configured to bring an engagement segment selectively into engagement with a threaded segment rotating with the shaft in order to cause a relative movement of the engagement segment and the threaded segment along the axis of the shaft to thereby activate the clutch in the axial direction,
- wherein the engagement segment is formed by a segment of one of an axially displaceable actuator element of the activation device and a radially mobile tappet of the activation device.
A coupling arrangement for a drive train of a motor vehicle, the coupling arrangement comprising:
- a shaft;
- a clutch arranged on the shaft to selectively couple the shaft with a drive element of the drive train;
- an activation device to open the clutch and selectively bring an engagement segment into engagement with a threaded segment rotating with the shaft in order to cause a relative movement of the engagement segment and the threaded segment along the axis of the shaft to thereby open the clutch,
- wherein:
- the threaded segment is formed by a portion of a sleeve connected rotationally fixed with the shaft and axially displaceable, to thereby to create a form-fit connection between the shaft and the drive element of the drive train;
- and
- an external thread is provided on the sleeve and forms the threaded segment which cooperates with an internal thread forming the engagement segment on an axially fixed part of the activation device.
A coupling arrangement for a drive train of a motor vehicle, the coupling arrangement comprising:
- a shaft configured for rotation;
- a clutch on the shaft and which is configured to couple the rotating shaft selectively with a drive element of the drive train;
- an activation device configured to open the clutch, wherein the activation device is configured to bring an engagement segment selectively into engagement with a threaded segment rotating with the shaft in order to cause a relative movement of the engagement segment and the threaded segment along the axis of the shaft to thereby open the clutch,
- wherein:
- the activation device comprises an actuator element having a carrier upon which is formed the engagement segment;
- the threaded segment is formed on the rotating shaft in a manner such that in order to open the clutch, the actuator element is displaceable along the axis of the shaft via the threaded segment;
- and
- the engagement segment of the carrier is configured for engagement with the threaded segment along a length of the threaded segment which corresponds to an axial adjustment distance of the actuator element.
