On the operating regime of a metal pushing V- belt CVT under steady state microslip conditions
Published August 23, 2004 by University of California-Davis in United States
Continuously variable transmissions (CVT) offer a continuum of gear ratios between desired limits. The present research focuses on developing models to understand the microslip behavior and to define an operating regime of a metal pushing V-belt CVT. Slip is modeled on the basis of gap redistribution between the elements. Studies were conducted to observe the influence of loading conditions (i.e. axial forces and torques) on the slip behavior and torque transmitting ability of the CVT. The model also investigates the range of axial forces needed to initiate the transmission and to successfully meet the load requirements. The mathematical model and the results corresponding to different loading scenarios are discussed.
