Abstract:
A method for compensating for angular misalignments for a variator of a continuously variable belt-drive transmission having a first cone pulley pair and a second cone pulley pair connected by a pushing linked band as a torque-transmitting element, the method comprising the following steps:selecting a curved outline of a first fixed cone pulley of the first cone pulley pair on a primary side of the variator; selecting a crowned pushing link flank outline of the pushing link band calculating a first displacement path of the pushing link band relative to the curved outline of the first fixed cone pulley and the crowned pushing link flank outline for all running radii of the pushing linked band about the first come pulley pair; assuming a compensating displacement path of the pushing link band for the second pair of cone pulleys relative to the known first displacement path to eliminate any angular misalignment of the pushing link band; and calculating an outline of the second pair of cone pulleys based on the compensating displacement path and the pushing link flank outline to ensure the pushing link band conforms to the compensating displacement path for the second pulley and eliminates angular misalignment of the pushing link band.
