Patent ID: 7574935

Claim:
A transmission having two cones as revolving transmission elements, each of which has at least one running surface for a revolving ring as a revolving coupling element, said at least one running surface having at least two running paths for the coupling element having different running radii, said ring surrounding one of said cones and passing through a constant gap between said transmission elements, said two transmission elements being braced, with the coupling element incorporated, via a bracing device which presses the two transmission elements against the coupling element with a variable pressure, wherein the bracing device comprises a pressure device ( 8 ), which presses the running surface ( 12 ) of a first of the two transmission elements ( 4 , 5 ) against the coupling element ( 7 ) with a variable pressure and, in addition, is supported on a bracing bearing ( 9 ), and a spring element ( 13 , 14 ) which is positioned to act in series with the pressure device.
