Toothed continuously variable transmission (CVT) - Industrial realization

Abstract

The developed toothed continuously variable transmission (CVT) in the form closed gear differential is reliable mechanical system which provides high load ability and reliability. Laws of mechanics allow creating the mechanical transmission, capable to bring a transfer ratio into accord to loading only due to properties of the mechanism without use of any control. The mechanism acquires property of adaptation to variable external loading. It allows using this transmission for machines which work in the intense force conditions. The account of transmission includes the correct selection of tooth wheels numbers and use of inertial properties of transmission at start up. The mechanical transmission with two degrees of freedom can change output shaft rotation if a stopping of one of wheels for simple creation of a back trailing of the car. © Springer Science+Business Media Dordrecht 2013.
