Abstract
An automatic transmission has: a primary transmission mechanism including: an input shaft; a planetary gear set having a sun gear, planetary gears and a ring gear, each being a helical gear, the ring gear and sun gear being respectively connected to the input shaft and to a stationary member via a one-way clutch, and a carrier for the planetary gears is connected to a primary output shaft; and an centrifugal clutch engaged/released the input shaft with/from the primary output shaft in correspondence with a centrifugal force by a weight and a thrust force by the helical gear; and a secondary transmission mechanism connected to the primary output shaft, for controlling a gear-shift into two or more speed-changed conditions. A multiplicity of change-speed gears is obtained by selectively combining the released and engaged states of the centrifugal clutch for each of the speed-changed conditions of the secondary transmission mechanism.
