Abstract

The invention relates to a clutch unit, which has two subunits. One subunit is connected to the output shaft of an engine, and the other subunit is pre-mounted on the side of the transmission. Both subunits are coupled to one another via an axial plug-type connection, which includes meshing first profiles and second profiles.

Claims (7)

1. A clutch unit, comprising:

at least two subunits, one subunit is connected to an output shaft of an engine and the other subunit is pre-mounted on a transmission side of the engine, both subunits are coupled to one another via an axial plug-type connection, which comprises first profile systems and second profile systems,

a plurality of first tooth-shaped profiles forms the first profile systems and a plurality of second tooth shaped profiles forms the second profile systems, the first tooth-shaped profiles in meshed engagement with the second tooth-shaped profiles, wherein one of the first tooth-shaped profiles and the second tooth-shaped profiles is tensioned in a circumferential direction by a tensioning element, the tensioning element has a plurality of tensioning tooth-shaped profiles and is supported by a component which has the one of the first tooth-shaped profiles and the second tooth-shaped profiles, and wherein the tensioning element is tensioned with respect to the component in the circumferential direction by at least one energy store,

wherein the one of the first tooth-shaped profiles and the second tooth-shaped profiles includes:

a corresponding group of tooth-shaped profiles, the tensioning tooth-shaped profiles of the tensioning element and the corresponding group of tooth-shaped profiles being respectively arranged axially one next to the other, and

further tooth-shaped profiles in the circumferential direction between the tensioning tooth-shaped profiles of the tensioning element, the further tooth-shaped profiles are at least partially offset axially relative to the corresponding group of tooth-shaped profiles in the direction of the tensioning tooth-shaped profiles of the tensioning element.

2. The clutch unit as claimed in claim 1 , wherein the tensioning tooth-shaped profiles of the tensioning element and the further tooth shaped profiles at least partially overlap in a circumferential direction.
