    摘要: A dual clutch transmission comprises a first clutch (C1) to be engaged for setting any one of forward-traveling odd-numbered speeds and a second clutch (C2) to be engaged for setting any one of forward-traveling even-numbered speeds. The dual clutch transmission establishes a desired forward-traveling speed by alternately engaging/disengaging the first and second clutches (C1,C2). A backward-traveling drive train is adapted to be driven by engaging one of the first and second clutches. When a reverse mode is established by a mode setting means, the one of the first and second clutches (C1) is engaged to drive the backward-traveling drive train (78,75,14a) by setting a speed change manipulator (95) at a backward-traveling position, and the other of the first and second clutches (C2) is engaged to drive a fixed one forward-traveling speed drive (73,77) train by setting the speed change manipulator at a forward-traveling position. While the reverse mode is established, the backward-traveling drive train (78,75,14a) and the fixed one forward-traveling speed drive train are kept activated regardless of whether the first or second clutch is engaged.

    摘要: A hydraulic servo 50 of a fourth clutch C-4 capable of transmitting the input rotation to a sun gear S2 is placed between the axial direction of a planetary gear unit PU and a speed reduction planetary gear DP, and hydraulic servos 20 and 40 of a first and third clutches C-1 and C-3 capable of transmitting the reduced speed rotation from the planetary gear DP to the sun gear S2 and S3 are placed on the side opposite in the axial direction from the planetary gear unit PU as to the hydraulic servo 50 of the fourth clutch C-4. The input shaft 12 and the fourth clutch C-4 are linked via the linking member 140 that passes outside the first and third clutch C-1 and C-3, and the first and third clutches C-1 and C-3 are each linked to the sun gear S2 and S3 via the linking members 101 and 102 that pass inside the fourth clutch C-4.

    摘要: An automatic transmission (11) includes a bicylindrical member (50) in which an inner cylinder portion (50a) and an outer cylinder portion (50c) are integratedly formed through a flange portion (50b), and which forms a portion of a clutch drum of a third clutch (C3). The inner cylinder portion (50a) structures a first base portion in which a piston (43) of a fourth clutch (C4) slides, and the outer cylinder portion (50c) structures a second base portion in which a piston (33) of the third clutch (C3) slides. An end portion (50d) of the outer cylinder portion (50c) is provided extending so as to run through a clutch drum (42) of the fourth clutch (C4), and the clutch drum (42) is restricted from detaching by a snap ring (51). The clutch drum (42) also contacts and supports a cancel plate (34), and is supported by the outer cylinder portion (50c). The clutch drum (42) is thus supported more toward an outer perimeter side, and even if the clutch drum (42) is subject to a centrifugal hydraulic pressure of a cancel oil chamber (37), deformation can be suppressed.
