Dual clutch including two clutch units acting in a force-fitting manner and mounted on a common clutch hub in a rotationally fixed and axially movable manner, a pressure disk arrangement retained between the clutch units on the clutch hub in an axially fixed manner and including two axially movable pressure pistons each of which can be ventilated by a compression spring arrangement positioned in the clutch hub. Each compression spring arrangement includes multiple compression springs, each of which is arranged in a recess of the clutch hub. Each recess is introduced into the clutch hub as an axially extending blind hole. The pressure disk arrangement is received in a radial groove of the clutch hub, the groove being radially and/or axially spaced from the blind holes.
A dual clutch comprising two clutch units mounted on a common clutch hub for conjoint rotation and axial movement in relation to an axis of clutch rotation, the dual clutch comprising a multipart pressure disk arrangement held in an axially fixed manner on the clutch hub between the clutch units, and two axially movable pressure pistons, each pressure piston being releasable by a compression spring arrangement positioned in the clutch hub, each compression spring arrangement comprising a plurality of compression springs, each of the compression springs being arranged in an aperture disposed in the clutch hub, each aperture comprising a blind hole, the pressure disk arrangement being disposed in a groove extending radially, in relation to the axis of clutch rotation, in the clutch hub, each of the blind holes extending axially inwardly, with respect to the axis of clutch rotation, within the clutch hub and having an axially innermost terminal end defined by a surface of the clutch hub disposed to close off the axially innermost terminal end, the blind holes being disposed in non-intersecting relation with the groove within the clutch hub.
The dual clutch as claimed in 7, wherein each pressure disk segment has an axially extending shoulder disposed at a radially inner area of the respective pressure disk segment, each shoulder having an axially extending surface facing radially outwardly, the carrier ring being disposed adjacent the axially extending surfaces.
