A dual shift coupling including two operatively connected coupling units mounted on a shared, integrally formed inner body in a rotationally fixed and axially movable manner. Further, a multi-part pressure disk is arranged between the coupling units in an axially fixed manner and is supported by the inner body, and has two axially movable pressure pistons ventilated by respective pressure spring assemblies arranged in the inner body. A radial notch for accommodating the pressure disk is provided in the inner body, wherein the radial depth of the notch extends at least to radial inner wall segments of recesses for the pressure spring assemblies. Each pressure spring assembly has a plurality of pressure springs which rest on the inner side of the pressure disk relative to the axis.
A dual clutch having two clutch units mounted in a rotationally fixed and axially movable manner, in relation to a clutch rotational axis, on a common, single-piece inner body, the dual clutch further including a pressure disk arranged in an axially fixed manner between the clutch units, the pressure disk being held on the inner body and being of a multiple-piece design, the dual clutch having two axially movable pressure pistons, each pressure piston being ventilated by one compression spring arrangement arranged in the inner body, wherein a radial groove is provided in the inner body in which the pressure disk is disposed, the radial groove having a depth which extends radially inwardly at least as far as radially inner wall sections of cutouts defined in the inner body in which the compression spring arrangements are disposed, and each compression spring arrangement comprising a plurality of compression springs having inner ends supported axially on the pressure disk.
A dual clutch having two clutch units mounted in a rotationally fixed and axially movable manner, in relation to a clutch rotational axis, on a common, single-piece inner body, the dual clutch further including a pressure disk arranged in an axially fixed manner between the clutch units, the pressure disk being held on the inner body and being of a multiple-piece design, the dual clutch having two axially movable pressure pistons, each pressure piston being ventilated by one compression spring arrangement arranged in the inner body, wherein a radial groove is provided in the inner body which receives the pressure disk, a radial depth of the radial groove extending at least as far as radially inner wall sections of cutouts for the compression spring arrangements, each compression spring arrangement comprising a plurality of compression springs supported axially on the inside on the pressure disk, the cutouts of axially opposite compression springs of the two compression spring arrangements being aligned axially with one another, and all of the cutouts which are aligned axially with one another in the inner body being formed in each case by through holes which penetrate the inner body completely axially.
A dual clutch having two clutch units mounted in a rotationally fixed and axially movable manner, in relation to a clutch rotational axis, on a common, single-piece inner body, the dual clutch further including a pressure disk arranged in an axially fixed manner between the clutch units, the pressure disk being held on the inner body and being of a multiple-piece design including at least two pressure disk sections adjoining one another in the circumferential direction and a single-piece circumferential carrier ring, the pressure disk sections being connected to one another radially on the outside by the carrier ring, the dual clutch having two axially movable pressure pistons, each pressure piston being ventilated by one compression spring arrangement arranged in the inner body, wherein a radial groove is provided in the inner body which receives the pressure disk, a radial depth of the radial groove extending at least as far as radially inner wall sections of cutouts for the compression spring arrangements, each compression spring arrangement comprising a plurality of compression springs supported axially on the inside on the pressure disk.
A dual clutch defining a clutch rotational axis and comprising:
