Abstract

An infinitely variable transmission has a pair of driving conical flanges arranged on a first shaft and a pair of driven conical flanges arranged on a second shaft. Each pair has one axially movable conical flange and one axially fixed conical flange. The transmission is equipped with a locking device which when necessary can frictionally lock at least one driving conical flange to a driven conical flange.
