A conical disk pair for a belt-driven conical-pulley transmission includes an input shaft that is rigidly connected to an axially fixed disk. An axially movable disk is rotatably carried on the shaft so that it is axially movable and rotationally fixed to the shaft. A torque sensor including shaped surfaces between which rolling elements are positioned and that axially shift a sensing piston when there is a change in the effective torque acting between the sensing piston and the shaft. The sensing piston has axially directed, circumferentially-spaced arms that extend from a side facing away from the axially movable disk and that include axial teeth that mesh with axial teeth of an input wheel rotatably carried on the shaft. A support ring is in contact with inner surfaces of the arms to maintain the teeth of the arms in engagement with the teeth of the input wheel.
