Abstract
A coupling arrangement for a drive train of a motor vehicle includes at least one clutch which is arranged on a rotating shaft in order to couple the rotating shaft optionally with a drive element of the drive train, in which to couple the rotating shaft with the drive element, a first clutch part and a second clutch part can be brought into a form-fit engagement with each other by moving one of the clutch parts along the axis of the rotating shaft. To prevent jerks and vibrations in the drive train, a hydraulic damping device is provided which acts between the first clutch part and the second clutch part.
Claims20
A coupling arrangement for a drive train of a motor vehicle, the coupling arrangement comprising:
- a clutch for arrangement on a shaft which is rotatable about an axis, the clutch including a first clutch part and a second clutch part;
- a first damping device to hydraulically dampen contact between the first clutch part and the second clutch part during engagement of the clutch;
- a second damping device to elastically dampen contact between the first clutch part and the second clutch part during engagement of the clutch;
- a spring to pretension the second clutch part in an engagement direction;
- an actuator device to activate the clutch, the actuator device having a ramp ring and a control ring which define a damping chamber of the first damping device;
- and
- a worm gearwheel which is rotatable about the axis of the shaft to axially displace the ramp ring along the axis of the shaft in a manner such that the second clutch part is also moved along the axis of the shaft via a sliding engagement with the ramp ring to thereby open the clutch.
