Abstract
An infinitely variable transmission has a first pair of conical flanges arranged on a first shaft and a second pair of conical flanges arranged on a second shaft, where each pair has an axially movable flange and an axially fixed flange. A torque-transmitting means is disposed between the pairs of conical flanges. Piston/cylinder units and plenum chambers comprising circular ring-shaped elements serve to apply pressure to and effect axial movement of the movable conical flanges. The ring-shaped elements have radially inner portions with openings to receive the shafts. The radially inner portion of at least one of the ring-shaped elements has a welded seam connecting the ring-shaped element to the shaft received by its opening.
