Abstract
A compact arrangement for a continuously variable transmission and power train system is provided to be used in rear wheel drive vehicles. In one arrangement, the input shaft is in-line with the output shaft. In this arrangement, the input shaft, having a hydraulic pump, is connected to an engine by a torque converter. A first transfer gear assembly transfers power from the input shaft to the adjustable input pulley of a continuously variable transmission assembly. The adjustable input pulley transfers power to an adjustable output pulley through a belt. A second transfer gear assembly transfers power from the adjustable output pulley to an output shaft in-line with the input shaft. A forward and reverse gear system having a compound planetary gear set and clutch on the output shaft provides forward, neutral, and reverse gears.
