  • Drivetrain for utility vehicle
    Publication number: 20070021245
    Abstract: A utility vehicle drivetrain includes an engine driving a continuously variable transmission (CVT) that drives a transaxle that drives at least one wheel. The continuously variable transmission has a CVT turn ratio defined as an engine output rotary speed into the CVT divided by a CVT output rotary speed into the transaxle. The transaxle has a transaxle turn ratio defined as the CVT output rotary speed divided by a transaxle output rotary speed to the at least one wheel. The transaxle turn ratio can be greater than five times the maximum CVT turn ratio. The transaxle turn ratio can be greater than twenty times the minimum CVT turn ratio. Th e transaxle turn ratio can be greater than 17.
