Scheme 226
General Operation
The continuously variable transmission (CVT) is an electronically controlled automatic transmission with drive and driven pulleys, and steel belt. The CVT provides non-stage speeds forward and one reverse.
Around the outside of the flywheel is a ring gear which meshes with the starter pinion when the engine is being started. The transmission has four parallel shafts: the input shaft, the drive pulley shaft, the driven pulley shaft, and the secondary gear shaft. The input shaft is connected to the flywheel, which is connected to the motor rotor. This is connected to the end of the engine crankshaft. The drive pulley shaft and driven pulley shaft consists of movable and fixed face pulleys. Both pulleys are linked by the steel belt.
The input shaft includes the sun gear and planetary gears with carrier. The drive pulley shaft includes the drive pulley and forward clutch. The driven pulley shaft includes the driven pulley, start clutch, and the secondary drive gear, which is integral with the park gear. The secondary gear shaft is positioned between the secondary drive gear and the final driven gear. The secondary gear shaft includes the secondary driven gear and the final drive gear, which serves to change the rotation direction, because the drive pulley shaft and driven pulley shaft rotate the same direction. When certain conditions of the planetary gears in the transmission are engaged by the forward clutch and the reverse brake, power is transmitted from the drive pulley shaft to the driven pulley shaft to provide the L, D, and R positions.
