    摘要: An automatic transmission including a double pinion planetary gear unit PG1, two single pinion planetary gear units PG2 and PG3 and six frictional elements (viz., six clutches) C1 to C6 is so constructed as to establish nine forward speeds and one reverse speed by simultaneously putting selected three of the six frictional elements C1 to C6 into their engaged condition. The frictional elements C1 to C6 are of a type including mutually rotatable friction plates that cause production of an oil dragging resistance when the frictional element is under idling condition. With the simultaneously engaged condition of the three frictional elements, each speed is established with a reduced friction loss of the automatic transmission.

    摘要: An automatic transmission includes a double-pinion planetary gearset and two single-pinion planetary gearsets. A first ring gear is held stationary. A second sun gear and a third ring gear are coupled to a first sun gear and a first carrier respectively, constituting first and second rotor units. An output is coupled to a third carrier. A first clutch selectively couples a second carrier to the first rotor unit. A second clutch selectively couples the second carrier to the second rotor unit. A third clutch selectively couples an input to the second carrier. A fourth clutch selectively couples a second ring gear to a third sun gear. A fifth clutch selectively couples the second ring gear to the third carrier. A sixth clutch selectively couples the input to the third sun gear. Nine forward gear ratios and one reverse gear ratio are obtained by simultaneous application of three of the clutches.
