    Abstract: An automatic transmission has a first axis (input axis) 102 for inputting the power, a second axis (output axis or couner axis) 103 for outputting the driving force source, at least one or more first gear group which consists of drive gears 111, 112 fixed on the first axis, and a driven gear 122 provided so as to engage or run idle with respect to the second axis with being engaged with the drive gear, and at least one or more second gear group which consists of driven gears 123, 124, 125 fixed on the second axis, and a drive gear 114, 115 provided so as to engage or run idle with respect to the first axis with being engaged with the driven gear. The automatic transmission further comprises a torque transferring mechanism 140 for transfering the torque between said driven gear which can run idle with respect to the second axis and the driven gear fixed to the second axis.

    Abstract: A mesh type automatic transmission is equipped with a plurality of shift gears arranged to rotate freely to an output shaft for providing driving force to the wheels. Cogged clutches 12, 15 engage with the output shaft. Counter shift gears corresponding to each speed are fixed to a counter shaft rotated by the rotation of an input shaft and mesh with the shift gears for performing automatic shifting by controlling engagement of one of the cogged clutches with the voluntary shift gears determined from the accelerator command value and the vehicle speed. An assist mechanism transmits rotational force of the input shaft to the output shaft via the assist shaft which rotates from the rotation of the counter shaft when no cogged clutch of the plurality of cogged clutches is engaged with any of the plurality of shift gears occurring during switching when an engaged cogged clutch of the plurality of cogged clutches is disengaged and one of the cogged clutch of the plurality of cogged clutches is to be engaged.

    Abstract: When shifting the gear position into a target gear position from a current gear position, some gear position different from said current gear position is used as one distributing gear position. The control unit controls the pressing load of a synchromesh of one distributing gear position to make at least part of the rotation torque from the drive power source transfer by the friction. Thereby it makes at least part of the rotation torque transferred by a synchromesh of the current gear position decrease. And then it moves the synchromesh of said current gear position to a disengaging position not meshed with said idle gear. Thereafter another gear position different from said target gear position and said one distributing gear position is used as another distributing gear position. So that it controls the pressing load of the synchromesh of another distributing gear to make the transfer torque increase gradually by the friction, and simultaneously makes the pressing load of the synchromesh of one distributing gear position decrease gradually. Besides such a distribution of transfer torque, it makes the speed of said input shaft synchronize with the speed corresponding to said target gear position by controlling the speed of said input shaft, and then moves the synchromesh of the target gear position to the meshing position.

    Abstract translation: 当从当前齿轮位置将齿轮位置转换到目标档位时，将与当前档位不同的一些档位用作一个分配档位。 控制单元控制一个分配齿轮位置的同步啮合的按压负载，以使得通过摩擦从驱动电源传递的至少一部分旋转扭矩。 因此，使当前档位的同步啮合传递的旋转力矩的至少一部分减小。 然后将所述当前档位的同步信号移动到不与所述空转齿轮啮合的分离位置。 此后，与所述目标齿轮位置和所述一个分配齿轮位置不同的另一齿轮位置用作另一分配齿轮位置。 从而控制另一个分配齿轮的同步啮合的压力负荷，使传递扭矩由于摩擦而逐渐增加，同时使一个分配齿轮位置的同步啮合的压力负荷逐渐减小。 除了传递扭矩的这种分布之外，通过控制所述输入轴的速度，使所述输入轴的速度与对应于所述目标档位的速度同步，然后将目标档位的同步色移动到啮合位置。
