A Transaxle Design for a Traction Continuously Variable Transmission for Automobiles 800102

A continuously variable, wide ratio range, traction transmission (CVT) is discussed as a transaxle design for automotive use. A configuration positively driving both wheels and eliminating a separate differential promises lower manufacturing costs, better vehicle performance and higher fuel mileage. The over 90% efficient and very quiet CVT depends on a traction design able to take a very high shock loading with a long maintenance free life. Traction requirements and solutions are discussed. Applications to I.C., electric and hybrid vehicles explain the need for a CVT with a wide ratio range.
