A disk set arrangement for a chain-CVT having a function-optimized disk set surface contour. The CVT includes a first drive disk set and a second driven disk set, wherein the disk sets of the disk set arrangement in each case include two disks mounted on respective shafts. One disk of each of the disk sets can be displaced axially relative to an opposed axially fixed disk. An endless chain arrangement with rocker pressure pieces is operative between the disk sets to transmit torque. The rocker pressure pieces have longitudinal axes that extend parallel to the rotational axes of the shafts, and include outer axial ends that contact the contoured disk surfaces.

A device for detecting the speed of an endless torque-transmitting member that passes around a pair of spaced conical pulley pairs of a continuously variable transmission. The device includes a sensor that is positioned adjacent the endless torque-transmitting member and that detects the speed of the endless torque-transmitting member at a point that is located relative to the movement course of the endless torque-transmitting member that is independent of the rotational speed relationship of the pulley pairs.

Apparatus for detecting the speed of an endless torque-transmitting member of a continuously variable transmission

A method and apparatus for regulating the transmission ratio of a continuously variable transmission. A set point value for adjusting the transmission ratio can be changed as a function of the operating parameters of a power train that includes the transmission. The set point value is composed of an initial control value and a regulating value. The initial control value depends on at least two operating parameters of the transmission. The set point value is updated to take into account changes that occur during operation of the transmission.
