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 first to third single-pinion planetary gearsets. The second ring gear and third sun gear are coupled to the first carrier and first ring gear respectively to constitute first and second rotor units. Input and output shafts are coupled to the second sun gear and third ring gear respectively. A first clutch selectively couples the first sun gear to the first carrier. A second clutch selectively couples the second sun gear to the third carrier. A third clutch selectively couples the second carrier to the second rotor unit. A fourth clutch selectively couples the second carrier to the third carrier. A first brake selectively holds the first sun gear stationary. A second brake selectively holds the third carrier stationary. At least eight forward gear ratios and one reverse gear ratio are obtained by simultaneous application of three of the clutches and brakes.
