Referring to the one-stage shifting process, in the neutral state, both the drive gear and the driven gear mounted to the input shaft 50 and the output shaft 60, 70 are free.

In this state, when the driver performs the first gear shifting operation, the sleeve of the synchronous mechanism 52 directly connected to the input shaft 50 is engaged with the clutch gear of the first / reverse drive gear 51 while moving to the right. The synchronization mechanism 73 on the second output shaft 70 is also coupled to the first stage driven gear 72 while moving to the right.

Therefore, the first stage / reverse drive gear 51 is rotated while being directly connected to the input shaft, and the first stage follower gear 72 engaged with the first stage / reverse drive gear 51 also rotates at the same time while synchronizing mechanism 73 and the second output shaft. The rotational drive force is transmitted to the deep shaft 80 through 70.

Next, the reverse shift process will be described. When the driver performs reverse shift, the two synchronous mechanisms 52 and 63 are coupled to the first gear / reverse drive gear 51 and the reverse driven gear 62, and the input shaft 50 is rotated. And the first output shaft, wherein the rotational power is transmitted to the first stage driven gear 72 of the second output shaft 70 through the first stage / reverse drive gear 51 directly connected to the input shaft 50, and the first stage. The driven gear 72 reversely rotates the first output shaft 60 through the reverse driven gear 62 and the synchronous mechanism 63, and this reverse rotation driving force is applied to the deep shaft 80 through the output gear 60. Delivered.

Therefore, the forward six-speed reverse single-speed manual transmission of the present invention constructed and operated as described above is provided with a synchronous mechanism on the input shaft so that all driving gears are not restrained when the gear is neutral, and the drive is directly connected even when power is transmitted. Since only the gear rotates, the entire idle gear can be reduced, which in turn has the advantage of reducing the noise generated by the gear rotation.
