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 carrier 54 of a third planetary gear mechanism 50 via a clutch C1 and also connected to a carrier 34 and a sun gear 31 of a first planetary gear mechanism 30 via clutches C2, C3, and furthermore the carrier 34 is connected to a sun gear 41 of a second planetary gear mechanism 40 and a third ring gear 52 respectively. And an output shaft 80 is connected to a third sun gear 51 and a second carrier 44. And, these clutches C1-C3 and brakes B1, B2 are selectively operated whereby first gear speed is secured by C1 and 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.
