Abstract
In order to provide for advantageous adjustment possibilities for an infinitely variable drive pulley for a belt drive transmission with two flanges arranged on a shaft and which accommodate a V-belt. One flange is fixed axially on the shaft and the other is moveable in the axial direction against the force of at least one return spring by centrifugal weights in the form of adjusting levers. The adjusting levers each acts on an abutment cam surface, and is supported so as to be able to pivot out about a pin that extends transversely to the shaft, spaced radially therefrom. The adjusting levers can be moved relative to their pivot pins through an adjustment eccentric.
