Transmission
First Claim
1. 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.

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.

19. A transmission having two revolving transmission elements, each of which has at least one running surface (50, 51) for a revolving coupling element, at least one of the running surfaces having at least two running paths for the coupling element having different running radii and actuating means being provided, via which the coupling element may be adjusted from one of the two running paths to the other of the two running paths and which comprises an activatable actuator (415, 416;
- 455), wherein the actuating means comprise a safety device which adjusts the coupling element into a safety running path if the activatable actuator breaks down.
