ABSTRACT:
An infinitely variable speed transmission in which the transmission ratio results from the equilibrium of the total contact pressure force on the one V-belt pulley and the contact pressure force on the other V-belt pulley determined by a V-belt. The total contact pressure force having a torque-dependent proportion and a proportion which is a function of at least one outside operating parameter.
