Abstract
Rotation of an input shaft is directly transmitted to a front carrier of a planetary gear mechanism, and rotation, which is speed-changed and reversed by a toroidal-type continuously variable speed change unit, is transmitted to a first sun gear. When a Low clutch is applied, rotation of an output carrier of a simple planetary gear unit is transitted to a counter gear mechanism via a common carrier, and then output at an output shaft. When a High clutch H is applied, rotation of a second sun gear is transmitted to the output shaft. Thus, the pinion shaft is shortened and the service life span of a supporting bearing is increased as compared with a planetary gear mechanism that has a three-step pinion.
