상기한 바와 같이 구성된 본 발명의 차량용 변속기는 도 5와 같은 작동표에 따라 각 변속단을 구성하게 되며, 이러한 작동상태는 도 6의 레버 다이어그램으로 정리될 수 있다.
The vehicle transmission of the present invention configured as described above constitutes each shift stage according to the operation table as shown in FIG. 5, and this operating state can be summarized by the lever diagram of FIG. 6.

특히, 본 발명의 변속기는 상기 제1선기어가 회전이 영구히 제한되도록 변속기케이스에 고정되어 있으므로 항상 속도가 0이며, 상기 제1유성기어장치(PG1)의 제1링기어(R1)와 제2유성기어장치(PG2)의 제2캐리어(C2)를 상기 제3클러치(CL3)로 가변 연결할 수 있도록 함으로써, 상기 제2선기어(S2)의 회전수가 일정 수준 이상 상승하는 경우를 상대적으로 줄여서 동력 전달 효율이 증대되도록 하고, 상기 제1유성기어장치(PG1) 및 제2유성기어장치(PG2)의 피니언기어, 피니언샤프트 및 니들롤러베어링의 내구성이 향상되도록 한다.
In particular, since the transmission of the present invention is fixed to the transmission case so that the rotation of the first sun gear is permanently limited, the speed is always 0, and the first ring gear R1 and the second planetary planet of the first planetary gear device PG1 are fixed. By allowing the second carrier C2 of the gear device PG2 to be variably connected to the third clutch CL3, the case where the rotation speed of the second sun gear S2 rises above a certain level is relatively reduced, thereby reducing power transmission efficiency. The pinion gear, the pinion shaft and the needle roller bearing of the first planetary gear device PG1 and the second planetary gear device PG2 are improved.

즉, 상기 종래의 구조에서는 제2클러치(CL2)가 작동되는 3속, 4속, 6속, 7속 및 후진3속의 경우에 제2선기어(S2)의 회전수가 최고속도로 회전하게 되지만, 본 발명에서는 제2클러치(CL2)와 제3클러치(CL3)가 함께 작동되는 4속, 6속 및 후진 4속의 경우에만 제2선기어(S2)의 회전수가 최고속도로 회전하게 되고 실질적으로 후진 4속의 사용 가능성이 낮은 점을 고려하면, 본 발명의 경우 제2선기어(S2)의 회전수가 최고속도로 회전하게 되는 경우가 대폭적으로 저감되어, 동력 전달 효율이 증대되고 관련 부품의 내구성이 향상되는 것이다.
That is, in the conventional structure, the rotation speed of the second sun gear S2 rotates at the maximum speed in the case of the third speed, the fourth speed, the sixth speed, the seventh speed, and the reverse third speed in which the second clutch CL2 is operated. In this case, the rotation speed of the second sun gear S2 is rotated at the maximum speed only in the case of the 4th, 6th and 4th speeds in which the second clutch CL2 and the third clutch CL3 are operated together. In view of this low point, in the present invention, the case where the rotational speed of the second sun gear S2 rotates at the maximum speed is greatly reduced, so that the power transmission efficiency is increased and the durability of related parts is improved.
