The disclosure relates to a disk () for a disk clutch () comprising an annular base element () which has a toothing () with multiple teeth () for achieving a rotary driving engagement with a disk carrier (), wherein the base element () has at least one hardened region () in which the base element () is designed as harder than in the tooth flank regions () of the teeth (). In addition, the disclosure relates to a disk clutch () with such a disk (), a double clutch device () with such a disk clutch (), and a method for producing such a disk ().

Disk, disk clutch with such a disk, double clutch device with such a disk clutch, and method for producing a disk

What is proposed is a variator disk for a toroidal variator, in particular for a motor vehicle toroidal transmission. The variator disk has a curved running surface which is oriented coaxially with respect to a variator axis and on which rollers of the toroidal variator can roll. The variator disk having furthermore at least two partial disks which are designed as a traction disk, on which the running surface is formed, and as a supporting disk, respectively. The supporting disk is designed for supporting axial forces applied to the running surface. The traction disk is supported on the supporting disk in the radial direction to the variator axis.

Variator disk and variator for a toroidal transmission

A variator arrangement is provided for a continuously variable transmission, having a shaft, a variator disk connected in a rotationally fixed manner to the shaft and a support disk which is concentric with said variator disk and which is rigidly connected to the shaft, the variator disk having a traction area on the side facing away from the support disk. For a rotationally fixed connection between the variator disk and the shaft, the variator disk and the support disk each have at least one recess which in cross section are each of approximately concave design and together hold a positive connection element which in cross section is of approximately convex lens-shaped design (FIG.).
