Abstract

In a transmission having two revolving transmission elements, each of which has at least one running surface for a revolving coupling element, at least one running surface having at least two running paths for the coupling element having different running radii and the two transmission elements being braced, while incorporating the coupling element, via a bracing device which presses the two transmission elements against the coupling element with a variable pressure, the bracing device comprises a pressure device connected in series with a spring element.
