Abstract
An infinitely variable cone pulley transmission arrangement which includes a loop or belt arranged to revolve around pairs of pulley discs which define a symmetrical pulley wedge. Each pair of pulley discs is provided with pressure devices which act through an axially slidable pulley disc. The slidable pulley discs are arranged on different sides of the belt or loop. The respective pressure devices are arranged on the same first side of the loop or belt with the slidable pulley disc which is located on the other side of the loop or belt being operatively connected to the associated pressure devices by a servo member which runs axially through the adjacent fixed pulley disc.
