Problems solved by technology
[0005] In a vehicular automatic transmission equipped with a plurality of planetary gear mechanisms, since the gear ratio control mechanism of each transmission unit is equipped with a unit that prevents one element gear of the planetary gear mechanism from rotating in one direction and allows it to rotate in the opposite direction, directional clutch, so the one-way clutch allows rotation at gear ratios other than those when the planetary gears are directly driven with engine braking and engine braking is not possible

Embodiment Construction
[0029] Refer below Figure 1 to Figure 6 One embodiment of the present invention is described.
[0030] like figure 1 As shown, the automatic transmission M to which the present invention is applied together with the internal combustion engine E as the prime mover constitutes a power unit, and the power unit is mounted on a motorcycle as a vehicle.
[0031] In this embodiment, the lateral direction and the longitudinal direction are consistent with those of the motorcycle on which the power unit is installed, and the vertical direction is an orthogonal direction.
[0032] In the description or in the scope of the claims, the axial direction is a direction parallel to the rotation centerline of the input shaft or output shaft of the transmission, and the radial direction and the circumferential direction are directions centered on the rotation centerline. When one of left or right represents one of the axial directions, the other of left or right represents the other of the a...

The present invention discloses a vehicular automatic transmission with planetary gear mechanisms. Engine braking can be realized at all gears of the vehicular automatic transmission, wherein the vehicular automatic transmission is equipped with a plurality of speed changing units with planetary gear mechanisms. The transmission is equipped with a unidirectional clutch which prevents the rotationof sun gears of planetary gear mechanisms to a direction and the rotation of gear ring of planetary gear mechanisms in a direction. An output shaft rotates with an output rotation speed which is obtained after performing speed changing to the input rotation speed of the input shaft through the planetary gear mechanisms. Furthermore an output shaft rotates a driving wheel of the vehicle and transfers the rotation of the output shaft to the unidirectional clutch of the input shaft when the output rotation speed exceeds the input rotation speed. Additionally, in the vehicular automatic transmission which is equipped with the speed changing units with the planetary gear mechanisms, a transmission mechanism which is equipped with an output introducing-out shaft and a neutral clutch is configured to the output side compactly.
