Abstract
PURPOSE:To secure such speeds of forward five-speed and backward one-speed that a gear ratio of the maximum speed is 1 by performing a speed change in making three sets of planetary gear mechanisms act on organically through first-third clutches and first and second brakes. CONSTITUTION:An input shaft 60 is connected to a ring gear 32, a carrier 34 and a sun gear 31 of a first planetary gear mechanism via clutches C1, C3 and also connected to a sun gear 41 of a second planetary gear mechanism 40 via the clutch C3 respectively. And, its carrier 44 is connected to a carrier 54 of a third planetary gear mechanism 50 and also connected to an output shaft 80, thus they are organically combined together via clutches C1-C3 and brakes B1, B2. Then, first gear speed is secured by actuation of the clutch C1 and the brake B1, second gear speed by C2 and B1, third gear speed by C1 and B2, fourth gear speed by C2 and B2, fifth gear speed of a gear ratio 1 by C2 and C3 and backward speeds by C3 and B1, respectively. Thus a range of the gear ratio is extendible and, what is more, the transmission efficiency of power is improvable.
