Abstract
Within the scope of the method for compensating angular misalignments for the variator of a continuously variable belt-drive transmission having cone pulleys disposed in pairs and one pushing linked band as torque transmitting belt-drive element, the fixed cone pulley of a variator side is designed with a curved outline, a pushing link displacement path being calculated with reference to a crowned pushing link flank outline and then the pushing link displacement path to the other side of the variator is calculated so that the displacement path is free of angular misalignment.
