Abstract (en)
[origin: WO2014067509A1] In a conical friction ring transmission, the safety device may have a normal state, in which electrical energy is applied to the safety device, and a failure state, in which the safety device is free of electrical energy, or a bi-stable safety actuator with a normal position and a failure position, and may change the effect parameter of a mechanical articulating element for adjusting a friction ring. An especially compact design of the conical friction ring transmission is thus achieved.
