Design and Analysis of a Modified Power Split Continuously Variable Transmission Andrew J. Fox The continuously variable transmission (CVT) has been considered to be a viable alternative to the conventional stepped ratio transmission because it has the advantages of smooth stepless shifting, simplified design, and a potential for reduced fuel consumption and tailpipe emissions. These benefits have driven all of the major automobile manufacturers to explore different designs of the CVT for the last century. Through this work, the CVT has been developed into a practical alternative to the conventional transmission for vehicles in the lower two thirds of the power spectrum.
