Abstract

PURPOSE:To simplify the construction by furnishing a two sets of planetary gearing mechanism of double pinion type, coupling No.1 carrier with No.2 sun gear and No.1 sun gear with No.2 carrier, and operating a clutch and brake selectively. CONSTITUTION:Existing invention includes No.1 planetary gearing mechanism 1 on the input shaft 13 side and No.2 planetary gearing mechanism 2 on the output shaft 15 side, wherein No.1 carrier 11 is coupled solidly with No.2 sun gear 4 and No.1 sun gear 3 with No.2 carrier 12, and No.1-3 clutches C1-C3 and No.1-3 brakes B1-B3 are put on selectively to perform multi-step speed change with six steps forward. For ex., C1, B1 causes the first speed, C2, B2 the second, C3, B1 the third, C2, B3 the fourth, C2, C3 the fifth, C3, B33 the sixth, and C1, B2 backward. This simplifies the total configuration, and multi-step speed change with five or six steps forward can be obtained.
