Transmitted torque, thrusts of driving and driven pulleys, and axial force between two pulleys were measured on a metal pushing V-belt type CVT. Thrust ratios between driving and driven pulleys at several different speed ratios were plotted with respect to torque ratio and compared with each other. It was found that the relation between thrust ratio and speed ratio was almost independent of rotational speed of the pulley and the maximum transmittable torque at a constant torque ratio. The thrust ratio is primarily a function of speed ratio. It also depends on torque ratio and coefficient of friction between blocks and a pulley. An empirical equation for pulley thrust balance was derived. The equation is expressed in an explicit form. It is so simple that it can be applicable for electronic control of CVT.
