Abstract: Continuously variable transmission (1) for motor vehicles, provided with a primary pulley (2) and a secondary pulley (3), around which there is arranged a drive belt (10), which is clamped between two conical pulley disks of the primary pulley (2) with a primary claming force and between two conical pulley disks of the secondary pulley (3) with a secondary clamping force, wherein, as a result of a contact angle of at least one of the pulley disks of the respective pulleys (2; 3) with the drive belt (10) being adapted, and at least in the largest transmission ratio of the transmission (1), i.e. Low, a clamping force ratio between the primary clamping force and the secondary clamping force has a value in the range between 1 and the clamping force ratio in the smallest transmission ratio, i.e. Overdrive.

Abstract: Continuously variable transmission provided with a primary pulley and a secondary pulley, around which a drive belt is arranged, clamped between two conical pulley discs of the respective pulley, a running surface of at least one pulley disc of the primary pulley and the secondary pulley, via which running surface this pulley disc contacts the drive belt, being provided, as seen in a cross section oriented perpendicular to a tangential direction, with a curvature, so that a pulley angle between a tangent on the running surface and a radial direction varies between a lowest value at the location of a radially innermost position on the running surface and a highest value at the location of a radially outermost position on the running surface. The curvature of the running surface of the primary pulley and that of the running surface of the secondary pulley differ from one another.
