Abstract
A continuously variable transmission having two pairs of conical disks operatively connected by an endless torque-transmitting belt. One of each of the disk pairs is axially movable relative to the other along a supporting shaft. The movable disk includes an inner tooth system that engages with an outer tooth system formed on the supporting shaft. The internal tooth system can be produced by a broaching process. The inner tooth system extends outwardly of the conical disk.
