이러한 5속 및 후진 1속의 파워 트레인에 있어서, 본 발명은 상기 입력축(2)과 출력축(4) 사이에 별도의 6속 변속기구(20, 수동 변속기구)를 배치한 것이 특징이 있다.In this 5-speed and 1-speed reverse power train, the present invention is characterized in that a separate six-speed transmission mechanism 20 (manual transmission mechanism) is disposed between the input shaft 2 and the output shaft 4.

상기 6속 변속기구(20)는 미도시한 운전석의 셀렉트 레버에 의하여 조작되는 수동 조작 변속기구를 적용하고 있는데, 본 발명에서는 상기 입력축(2)의 후단부에 6속 입력기어(22)를 배치하고, 출력축(4)의 후단부에 상기 입력기어(22)의 회전동력을 전달받는 6속 드리븐 기어(24)를 배치하며, 상기 6속 드리븐 기어(24)의 일측에 셀렉트 레버의 조작에 의하여 단속할 수 있는 동기기구(26)를 배치하여 이루어진다.The sixth speed shift mechanism 20 employs a manually operated shift mechanism operated by a select lever of a driver's seat, not shown. In the present invention, the sixth speed input gear 22 is disposed at the rear end of the input shaft 2. And a sixth speed driven gear 24 receiving the rotational power of the input gear 22 at the rear end of the output shaft 4, and by operating a select lever on one side of the sixth speed driven gear 24. It is made by arranging the synchronization mechanism 26 which can control.

상기 동기기구(26)는 공지에서와 같이, 클러치 허브(28), 슬리이브(30), 싱크로나이저 링(32)등으로 이루어지는 싱크로나이저 기구로 이루어지는바, 상세한 구성 설명은 생략하기로 한다.The synchronizing mechanism 26 is made of a synchronizer mechanism made of a clutch hub 28, a sleeve 30, a synchronizer ring 32, etc., as is known in the art, and a detailed description thereof will be omitted.

상기에서 6속 입력기어(22)와 6속 기어(24)의 기어비는 파워 트레인의 5속 변속비 보다 큰 증속이 이루어질 수 있도록 설정된다.In the above, the gear ratio of the sixth speed input gear 22 and the sixth speed gear 24 is set so that a speed increase larger than the five speed speed ratio of the power train can be achieved.

At the same time, the sixth speed gear 24 and the output shaft 4 are connected to each other by the operation of the synchronization mechanism 26 in the neutral state.

이상에서와 같이 본 발명에 의하면, 기존의 5속 파워 트레인의 간단한 구조 변경으로 6속화를 실현함으로써, 새로운 파워 트레인의 개발 비용을 절감하고, 변속단별 감속비 차이를 줄여 운전성능 및 연비향상에 기여할 수 있는 발명인 것이다.As described above, according to the present invention, by realizing the six-speed by the simple structure change of the existing five-speed power train, it is possible to reduce the development cost of the new power train, and contribute to the improvement of the driving performance and fuel efficiency by reducing the difference in the reduction ratio for each gear stage. It is an invention that there is.
