Frictional dynamics of the overrunning clutch for pulse-continuously variable speed transmissions: rolling friction

摘要

The overrunning clutch for pulse-continuously variable speed transmissions (pulse-CVT) is a roller-type mechanism whose working condition is different from the conventional types of overrunningclutches. This paper studies the rolling friction of this clutch with the dynamic effect of the operationof the pulse-CVT. The contribution of elastic hysteresis and viscous shear to the rolling friction of theclutch is analyzed.
