Automatic transmission mechanism

Abstract

Abstract PURPOSE:To make the transmission mechanism more compact with a predetermined permissible input torque maintained, by inputting a torque from an input member to a ring gear in a planetary gear unit. CONSTITUTION:Carriers CR1 and CR2 of a single planetary gear unit 12 and a dual planetary gear unit 13 are integrated to form a carrier CR, and sun gears S1 and S2 of the planetary gear units 12 and 13 are also integrated to form a sun gear S. The carrier CR is connected to an output member O. An input member I is connected through a first clutch C1 to a ring gear R1 of the single planetary gear unit 12, and is also connected through a second clutch C2 to the sun gear S. Further, the sun gear S and a ring gear R2 of the dual planetary gear unit 13 are adapted to be stopped by a stopper means such as brakes B1, B2 and B3 and one-way clutches F1 and F2.
