Abstract
A step ratio power transmission provides a plurality of drive ratios between the input and output shafts. The power transmission, in addition to the input and output shafts, has a countershaft on which a plurality of ratio gears are rotatably mounted. The input shaft has at least one ratio gear rotatably mounted thereon while the output shaft has at least one gear secured thereto. A cluster gear is secured to either the input shaft or the output shaft while the other of these shafts has roatably mounted thereon one or more ratio gears. At least one of the ratio gears on the input shaft serves as an idler gear for one or more of the ratio gears on the countershaft.
