ABSTRACT:
The pulleys of a pulley transmission, such as a CVT, are constructed such that one flange is drivingly connected to a shaft by means of a flexible, pliable, spring-like straps or a pack of relatively thin straps. Because the pulley flange which can be axially movable with respect to the shaft, is radially supported by a hub encircling the shaft, only one strap or strap-pack need be provided.
