Analytical model of sliding friction in an overrunning clutch

The overrunning clutch for pulse-continuously variable speed transmissions (Pulse-CVT) is a roller type of mechanism whose working condition is different from the conventional overrunning clutch. This paper studies the sliding friction of this clutch with the consideration of the dynamic effect of its operation. Both try and lubricated frictions are numerically analyzed. Distributions of the friction among the clutch components are numerically investigated and power loss is estimated.
