ABSTRACT:
A variable ratio transmission has a rotating drive cone with a gear at its narrowest diameter end to provide a non-slip high torque drive in low gear. A worm gear and drive shaft smoothly move an output drive disk back and forth along the drive cone to provide a smooth infinitely adjustable gear ratio to the output drive shaft. A slip clutch and forward, neutral, reverse transmission make the system suitable for motor vehicles especially trucks.
