Metal V-belt Continuously Variable Transmission Shifting Principle

Abstract:

It is important for continuously variable transmission (CVT) speed ratio control that gets to the bottom of the CVT shifting principle. In this paper, through analyzing the relative quantities of CVT shifting, a new shifting model is developed based on the CVT dynamic model. After the simulation analysis of new CVT shifting model made a measured condition as the input in the MATLAB\Simulink, it proved that this simulation using the new shifting model can get consistent results with the measurement data in car. And compared with CMM model simulation results, it can find two faults of CMM model: one is the shifting range is too lager; the other is the shifting rate oscillation, but the new variator shifting model can solve these problems.
