ABSTRACT:
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.2).
