Title: Design study of steel V-belt CVT for electric vehicles

Abstract

An engineering design study was conducted and the necessary analysis were performed to determine the optimum arrangement of a steel V-belt continuously variable transmission (CVT) to couple the high-speed output shaft of an energy storage flywheel to the drivetrain of an electric vehicle. The CVT included the variable speed elements along with the necessary clutches and gear sets. Based on the results of the study, a specific arrangement was recommended and a design layout was prepared. Technology advancements necessary to develop the CVT to satisfy the design criteria were identified. In addition, the scalability of the CVT to larger 10,000 kg (22,000 lb) and smaller 790 kg (1750 lb) vehicles was briefly studied. Evaluation of the steel V-belt CVT for use on straight electric vehicles or on internal combustion engine/battery hybrid vehicles was also considered. The study concluded that: a steel V-belt CVT of this general type could be scaled by classical means to larger or smaller vehicles by an appropriate choice of a gear set between the CVT and flywheel; the functional requirements for application of the steel V-belt CVT in the drive-line of straight battery powered vehicles, could be easily met by a single belt version which wasmore » substantially simpler, smaller, and less costly than that required for flywheel-assisted vehicles; and the application of a steel V-belt CVT in the driveline of a battery-assisted internal combustion engine hybrid vehicle was judged to be feasible.« less
