摘要： PROBLEM TO BE SOLVED: To realize forwarding five speed and backwarding one speed by three planetary gears and four friction elements, to miniaturize and lighten a gear train and to improve motive power efficiency. SOLUTION: This gear train is furnished with three planetary gears PG1-PG3 to be fixed and variably connected on and to specific elements, four friction elements to selectively and variably connect an input shaft, each element of the planetary gears and a housing of a transmission, first, second and third clutches C1-C3 and a first brake B1 so as to realize forwarding five speed and backwarding one speed by controlling these planetary gears.

摘要： PROBLEM TO BE SOLVED: To reduce the speed by providing a belt having an internal tooth gear made of the flexible raw material, concentrically providing an inner wheel having an external tooth gear inside of the belt, and pushing the belt to the inner wheel with a pushing roller provided outside the belt. SOLUTION: An outer wheel 22 made of the flexible raw material and provided with through holes 22b, 22b, with a constant space in the periphery of a flange 22a thereof is fitted on a large diameter part 16b of a driving shaft 16. Pins 24, 24 are loosely fitted in the through holes 22b, 22b,..., and a gear 26 to be engaged with a gear 18 is provided at the inner end of each pin 24, 24.... A belt 28 of the flexible raw material is provided in the outer ends of the pins 24, 24... and arranged in a space at a position close to a pump. Furthermore, shafts 30a, 30a of pushing rollers 30 are fitted in upper grooves between a driving side fixed frame 12 and a driven side fixed frame 14, and the pushing rollers 30 contact with the belt 28 of the flexible raw material for pushing. With this structure, number of revolution of a motor can be easily lowered with the simple structure.

摘要： PROBLEM TO BE SOLVED: To enable a large change of reduction ratio in the case of approaching and in the case of returning by selectively taking the rotary output from an epicyclic gear mechanism and the rotary output from a Ferguson mechanism. SOLUTION: A pulse motor 1 capable of being rotated normally and reversely is fixed to an outside end surface of an input side case 2 provided with an inner gear, and an input shaft 3 is extended inward of the input side case 2, and a pinion 4 is fixed to the input shaft 3. Three epicyclic gears 6 to be engaged with the pinion 4 and while commonly engaged with an inner gear of the input side case 2 and an inner gear of a rotor 12 are arranged in the periphery of the pinion 4 with an equal space, and installed between two rotary support plates 7 freely to be rotated by each support shaft 19, and a Ferguson mechanism is thereby structured. The rotary output from the Ferguson mechanism and the rotary output from the epicyclic gear mechanism are selectively taken out.

摘要： PROBLEM TO BE SOLVED: To favorably reflect learning of grip-change between frictional engagement elements on shift control by including an oil pressure control changing means changing the control mode of oil pressure for at least one of the first and second frictional engagement elements according to the shifting state of a sub-transmission in an automatic transmission. SOLUTION: An automatic transmission 4 capable of attaining shifting from a first shift step to a second shift step, an oil pressure control means 5, and a sub-transmission 80 are arranged. The oil pressure control means 5 includes an oil pressure control changing means changing the control mode of oil pressure for at least one of a first frictional engagement element (a second brake) 23 and a second frictional engagement element (a second clutch) 17 according to the shifting state of the sub-transmission 80. Hereby the control mode of oil pressure for at least one of the first and second frictional engagement elements 23, 17 can be favorably changed according to the shifting state of the sub-transmission 80.
