Abstract

A clutch device for a drive train of a motor vehicle includes a torsional vibration damper with an output side, a disconnect clutch with a clutch component, and a fastening unit releasably connecting the disconnect clutch to the torsional vibration damper. The fastening unit includes a first toothing region fixed on the clutch component, a second toothing region fixed on the output side and positively rotationally connected with the first toothing region, and a clamping element. The clamping element is arranged to preload the first toothing region relative to the second toothing region in a circumferential direction with a preloading force, and preload the output side relative to the clutch component with an axial contact pressure.

First claim

1 .- 10 . (canceled)

11 . A clutch device for a drive train of a motor vehicle, comprising:
a torsional vibration damper comprising an output side; a disconnect clutch comprising a clutch component; and a fastening unit releasably connecting the disconnect clutch to the torsional vibration damper, the fastening unit comprising:
a first toothing region fixed on the clutch component;
a second toothing region fixed on the output side and positively rotationally connected with the first toothing region; and
a clamping element arranged to:
preload the first toothing region relative to the second toothing region in a circumferential direction with a preloading force; and
preload the output side relative to the clutch component with an axial contact pressure.

12 . The clutch device of claim 11 , wherein:
the torsional vibration damper is designed as a dual-mass flywheel comprising a primary wheel; and the output side is a driver disc rotatable relative to the primary wheel to damp a torsional vibration.

13 . The clutch device of claim 11 , wherein the disconnect clutch comprises:
a first clutch component arranged to receive the first toothing region; and a second clutch component arranged to be coupled to the first clutch component.

14 . The clutch device of claim 13 , wherein:
the second clutch component is arranged to be connected for conjoint rotation with an intermediate shaft; and the first clutch component is arranged to be rotatably mounted on the intermediate shaft.

15 . The clutch device of claim 14 wherein the first clutch component and the second clutch component are arranged on the intermediate shaft such that an actuating force applied by an actuating unit to close or open the disconnect clutch is supported via the intermediate shaft.

16 . The clutch device of claim 11 wherein the disconnect clutch is designed as a single-disc clutch or a multiple-disc clutch.

17 . The clutch device of claim 11 further comprising a centrifugal-force pendulum device fastened to the clutch component.

18 . The clutch device of claim 17 wherein:
the clutch component comprises a cup-shaped carrier; and
the centrifugal-force pendulum device is fastened to a radial outer side of the cup-shaped carrier.

19 . The clutch device of claim 17 wherein:
the disconnect clutch comprises a plurality of friction elements; and
the centrifugal-force pendulum device is arranged at least partially in an axial direction at a same height as the plurality of friction elements.

20 . The clutch device of claim 17 wherein:
the torsional vibration damper comprises a plurality of damper springs; and
the centrifugal-force pendulum device is arranged axially next to the plurality of damper springs; or
the clamping element is arranged radially within the centrifugal-force pendulum device and the plurality of damper springs.
