C ontinuously V ariable T ransmissions ( CVT s) are a powerful alternative to automatic gearboxes for passenger cars. Some of these CVTs transmit the power via traction forces through highly loaded lubricated contacts. The aim of the presented work is to increase the capability of this system by means of appropriate engineering ceramics. The modifications are investigated on a machine element test bench. The necessary new tools for the design process and the configuration of the test bench are presented. Measurements show that the desired improvements can be achieved by using engineering ceramics but lifetime requirements have not been met yet.
