摘要： A compact automatic transmission for a vehicle capable of preventing increase in relative rotational speed between shift elements. A planetary gear unit is provided with a sun gear to which rotation of an input shaft is input, a carrier that can be stopped from rotating, and a ring gear for outputting, to a planetary gear set, rotation that is reduced in speed relative to that of the input shaft. A clutch is connected/disconnected, the input shaft and the sun gear are appropriately connected/disconnected, and the carrier is appropriately stopped/unstopped by a brake and a one-way clutch. This prevents relative rotational speed between shift elements of the gear unit that does not participate in a shifting operation from excessively increasing. When the clutch is disposed between the input shaft and the sun gear, the torque capacity of the clutch can be reduced as compared with the case where it is disposed between the gear unit and the gear set. Therefore, the clutch can be formed into a more compact structure and the overall automatic transmission can be made more compact.

摘要： An automatic transmission is configured to achieve at least ten forward speeds and one reverse speeds. This is achieved through the use of two planetary gear sets with a plurality of clutches and brakes configured to operably couple different components of the two planetary gears to achieve different speeds. For example, operation of a first clutch inputs decelerated rotation of a reduction planetary gear to a third sun gear. Operation of a second clutch transmits from an input shaft to a third ring gear, a third clutch inputs decelerated rotation of the reduction planetary gear to the second sun gear, a fourth clutch transmits from the input shaft to the second carrier, a first brake prevents a second sun gear from rotating, a second brake prevents a carrier from rotating, a third brake capable prevents a third ring gear from rotating.

摘要： A first planetary gear unit PR and a clutch C3 for outputting reduced speed rotation are located on one axial side of a second planetary gear unit PU, and a clutch C1 for connecting and disconnecting an input shaft 2 to/from a sun gear S2 and a clutch C2 for connecting and disconnecting the input shaft 2 input to/from a carrier CR2 are located on the other axial side of the second planetary gear unit PU. An output mechanism is located between the first and second planetary gear units. As compared with a drivetrain wherein the clutch C1 or clutch C2 is located between the two planetary gear units, the two planetary gear units can be located closer together, and a transmitting member that transmits the reduced speed rotation can be made shorter. Further, compared to a drivetrain wherein the clutches C1, C2, C3 are located together on one axial side, the oil supply to the hydraulic servos can be simplified.

摘要： Uncomfortable travel of a vehicle due to engine brake actions during the travel of the vehicle in traffic is prevented without using an one-way clutch within a transmission mechanism. An automatic transmission is composed of rotational elements that are braked at the time of establishing low stages, a brake that brakes the rotational elements, and control systems which control the oil pressure of the hydraulic servo in the brake. A band brake that creates differences in application forces, using self-energizing and deenergizing actions, serves as the brake, which is set to have an area in which the oil pressure during the drive is lower than the oil pressure during the non-drive, by setting the self-energizing direction as a direction of rotation of the rotational element during the drive and the deenergizing direction as an opposite direction of rotation of the rotational element during the non-drive. The control systems have a supplying mechanism which supplies oil to the hydraulic servo of the band brake at an oil pressure that is lower than the oil pressure during the non-drive and is equal to or higher than the oil pressure during the drive.

摘要： A 5-speed automatic transmission for a vehicle having a highly efficient top gear, a compact construction and a wide overall range of gear ratios. The automatic transmission has a speed changer which provides five gear stages, namely two speeds on the speed decreasing side and two speeds on the speed increasing side with a direct-coupled gear therebetween. The speed changer includes a ring gear connected to an output shaft, a first carrier, a first sun gear, a second carrier connected to the first carrier, a stepped pinion gear supported by these two carriers, and a sun gear meshing with the pinion gear. The first carrier is connected to an input shaft by a clutch and the first sun gear is connected to the input shaft by a clutch. The first sun gear may be stopped by a first brake, a second brake stops the second sun gear and a third brake is provided to stop a third sun gear. Top gear is achieved by meshing of the pinion gear with the second sun gear and the ring gear. Top gear is thus achieved with the equivalent of only one planetary gear set of intermeshing elements and without loss of efficiency. Also, the arrangement of the three planetary gear sets of the transmission is such that one planetary gear set can be easily removed to make a 4-speed transmission derived from the 5-speed transmission of the invention.
