ABSTRACT:
An infinitely variable transmission, method of controlling an infinitely variable transmission, and an apparatus utilizing the method. The infinitely variable transmission provides a lever or walking beam having a variable fulcrum point. Power is supplied to one end of the lever, for example by cams on a driving shaft. Power is taken from the other end of the lever by use of a rack cooperating with a gear mounted to a one-way clutch on a driven shaft. The method controlling the infinitely variable transmission includes measuring the intake manifold pressure of the internal combustion engine driving the transmission and displacing the fulcrum point of the lever in response to the measurement obtained to vary the transmission ratio. The apparatus disclosed for accomplishing this method includes a cylinder and piston assembly, the piston being interconnected with the movable fulcrum, a vacuum gage measuring intake manifold pressure and a source of pressurized fluid, and a valve selectively operable in response to the vacuum gage to pressurize the cylinder on one side of the piston.
