Abstract

A continuously variable drive mechanism has PA1 a variator with two conical disks, at least one of the conical disks being axially movable, PA1 a belt running at a variable running radius axially between the conical disks, and PA1 a disk-tightening device pushing the axially movable conical disk against the other of the two conical disks, thereby applying axial pressure to the flexible torque-transmitting device. The disk-tightening device works with guiding means converting a rotational displacement into an axial displacement.
