Description

5단 및 6단 겸용 수동변속기{manual transmission for combined use for 5 speed and 6 speed}Manual transmission for combined five and six speeds {manual transmission for combined use for 5 speed and 6 speed}

본 발명은 수동변속기의 구조에 관한 것으로서, 보다 상세하게는 거의 동일한 구조를 가지면서, 조립부품의 간단한 교체로 5단 수동변속기 또는 6단 수동변속기로 변경될 수 있는 수동변속기의 구조에 관한 것이다.The present invention relates to a structure of a manual transmission, and more particularly, to a structure of a manual transmission having almost the same structure, which can be changed to a five-speed manual transmission or a six-speed manual transmission by simple replacement of the assembly parts.

도 1에는 종래의 일반적인 5단 수동변속기가 도시되어 있는바, 엔진으로부터의 동력을 클러치를 통해 전달받는 입력샤프트(100)와, 상기 입력샤프트와 평행하게 배치된 출력샤프트(102) 및, 상기 출력샤프트로부터의 회전력을 좌우의 드라이브샤프트로 차동하여 제공하는 디퍼렌셜(104)로 구성되어 있으며,1 shows a conventional five-speed manual transmission, which includes an input shaft 100 receiving power from an engine through a clutch, an output shaft 102 disposed in parallel with the input shaft, and the output. It is composed of differential 104 which provides differential torque from the shaft to the drive shaft on the left and right,

상기 입력샤프트(100)와 출력샤프트(102)는 도면상 우측으로부터 좌측을 향하여 1단으로부터 5단에 이르는 변속단기어들이 설치되어 있어서, 이들 변속단기어들이 각각 싱크로기구에 의해 선택되어, 입력샤프트(100)로부터의 회전력을 해당 변속단기어의 기어비에 따라 출력샤프트(102)로 전달하도록 되어 있다.The input shaft 100 and the output shaft 102 are provided with gear shift gears ranging from the first gear to the fifth gear from the right side to the left side of the drawing, and these gear shift gears are selected by the synchro mechanism, respectively. The rotational force from 100 is transmitted to the output shaft 102 in accordance with the gear ratio of the shift gear.

여기서, 5단 변속단 기어와 4단 변속단 기어의 사이에는 중간베어링(106)이 설치되어 입력샤프트(100) 및 출력샤프트(102)를 지지하도록 하고 있고, 상기 입력샤프트(100) 및 출력샤프트(102)의 좌측 단부에는 각각 체결너트(108)가 체결되어서 싱크로기구 및 변속단기어를 지지하도록 하고 있다.Here, the intermediate bearing 106 is installed between the 5-speed gear and the 4-speed gear to support the input shaft 100 and the output shaft 102, and the input shaft 100 and the output shaft. A fastening nut 108 is fastened to the left end of 102 to support the synchro mechanism and the shift gear.

그런데, 최근에는 수동변속기의 동력성능을 보다 향상시키기 위해 6단 수동변속기의 요구가 급증하고 있는바, 이에 대응하기 위하여 상기한 바와 같은 종래의 5단 수동변속기의 구조에 6단 변속단 기어를 추가하고 싱크로기구가 이 6단 변속단 기어를 선택할 수 있도록 하는 방법이 모색되고 있으나, 상기한 바와 같은 종래의 변속기 구조를 기반으로 하여 상기한 바와 같이 새로운 변속단 기어를 추가하게 되면 변속기의 전장이 크게 증가하여 탑재성이 불리하며 중량이 증가하는 등의 문제점이 있다.However, in recent years, the demand for a six-speed manual transmission is rapidly increasing to further improve the power performance of the manual transmission. To cope with this, a six-speed gear is added to the structure of the conventional five-speed manual transmission as described above. However, a method of allowing the synchro mechanism to select this six-speed gearbox is being sought, but based on the conventional gearbox structure as described above, adding a new gearbox as described above greatly increases the overall length of the transmission. There is a problem such as an increase in the mountability and increase in weight.

아울러 상기한 바와 같은 종래의 수동변속기 구조는 상기 중간베어링(106)을 설치하기 위하여 수동변속기 케이스 내부가 중간벽(110)에 의해 크게 2부분으로 나뉘어짐에 따라 윤활유의 흐름이 원활하지 못하고, 이 또한 변속기의 전장을 증가시키는 요인으로 작용한다는 문제점이 있다.In addition, in the conventional manual transmission structure as described above, as the inside of the manual transmission case is divided into two parts by the middle wall 110 in order to install the intermediate bearing 106, the flow of lubricant is not smooth. In addition, there is a problem that acts as a factor to increase the overall length of the transmission.

이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 6단 변속기를 구성하면서도 변속기의 전장이 크게 증가하지 않고, 약간의 부품 교체로 5단 변속기와 6단 변속기를 각각 손쉽게 구성할 수 있으며, 아울러 변속기 내부의 윤활성 증대 및 중량 저감의 효과를 동시에 가져올 수 있도록 하는 5단 및 6단 겸용 수동변속기를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, but the overall length of the transmission does not significantly increase while configuring the six-speed transmission, it is possible to easily configure the five-speed transmission and the six-speed transmission respectively by a small part replacement. In addition, it is an object of the present invention to provide a five-speed and six-speed manual transmission that can bring about the effect of increasing the lubricity and weight reduction inside the transmission.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 5단 및 6단 겸용 수동변속기의 구조를 도시한 것으로서 6단 수동변속기의 상태를 도시한 도면이고, 도 3은 본 발명에 따른 5단 수동변속기의 상태를 도시한 도면이다.Figure 2 is a view showing the structure of a five-speed and six-speed manual transmission in accordance with the present invention showing a state of a six-speed manual transmission, Figure 3 is a view showing a state of a five-speed manual transmission according to the present invention. to be.

도시된 바와 같이, 변속기케이스(1)는 중간벽을 제거하여 자체로서 하나의 단일 공간만을 구성하도록 되어 있어서, 그에 따른 중량저감 및 변속기전장의 축소가 이루어지게 된다.As shown, the transmission case 1 is configured to remove only the intermediate wall and constitute only one single space by itself, thereby reducing weight and reducing transmission length.

상기 변속기케이스(1)의 후방 내측에는 베어링 지지부(1-1)가 구성되어 입력샤프트(3) 및 출력샤프트(5)를 각각 그 끝단에서 엔드베어링(7)으로 상기 베어링 지지부(1-1)에 지지한다.A bearing support part 1-1 is formed at the rear inner side of the transmission case 1 so that the bearing support part 1-1 is connected to the input shaft 3 and the output shaft 5 with end bearings 7 at their ends, respectively. To support.

여기서, 상기 입력샤프트(3)의 엔드베어링(7-1)은 스냅링(9)에 의해 입력샤프트(3)에 지지되어 있는 구조이고, 상기 출력샤프트(5)의 엔드베어링(7-2)은 그 자체가 테이퍼롤러베어링으로 출력샤프트(5)의 축방향 하중을 지지할 수 있도록 되어 있어서 별도의 스냅링은 설치하지 않은 구조이다.Here, the end bearing 7-1 of the input shaft 3 has a structure supported by the input shaft 3 by the snap ring 9, and the end bearing 7-2 of the output shaft 5 is The taper roller bearing itself is capable of supporting the axial load of the output shaft 5 so that a separate snap ring is not provided.

한편, 상기 입력샤프트(3) 및 출력샤프트(5)는 6속의 변속단을 형성하기 위하여 서로 대응하는 위치에 6단 변속단기어가 삽입될 공간부(11)를 각각 구비하고 있다.On the other hand, the input shaft (3) and the output shaft (5) is provided with a space portion 11 into which the six-speed gears are to be inserted, respectively, at positions corresponding to each other to form six-speed gears.

상기한 바와 같은 변속기의 구조를 기초로 하여 상기 입력샤프트(3) 및 출력샤프트(5)의 공간부(11)에 6단 변속단기어(13)를 삽입하면 6단 변속기를 구성하게 되는 한편, 상기 입력샤프트 및 출력샤프트의 공간부(11)에 스페이서(15)를 삽입하면 5단 변속기를 구성하게 되는 것이다.On the basis of the structure of the transmission as described above, if the six-speed gearbox 13 is inserted into the space 11 of the input shaft 3 and the output shaft 5, the six-speed transmission is constructed. When the spacer 15 is inserted into the space 11 of the input shaft and the output shaft, a five-speed transmission is constructed.

따라서, 상기 스페이서(15)와 6단 변속단기어(13)만을 서로 교체하여 조립하면 5단 변속기와 6단 변속기를 각각 용이하게 구성할 수 있게 된다.Therefore, when only the spacer 15 and the six-speed gear 13 are replaced with each other, the five-speed gearbox and the six-speed gearbox can be easily configured.

상기 변속기케이스(1)는 종래와는 달리 중간벽(110)을 제거한 단일 통형으로 구성됨으로써, 상기 중간벽의 제거에 따른 중량저감을 효과를 발휘함은 물론, 내부의 윤활유의 흐름을 차단하지 않게 되어 윤활성을 크게 향상시키게 되며, 변속기의 전장의 축소하는 효과를 아울러 발휘하게 된다.Unlike the conventional case, the transmission case 1 is configured in a single cylindrical shape in which the intermediate wall 110 is removed, thereby exerting a weight reduction effect due to the removal of the intermediate wall, and not blocking the flow of lubricant therein. Therefore, the lubricity is greatly improved, and the overall length of the transmission is reduced.

또한, 종래에 입력샤프트 및 출력샤프트의 단부에서 싱크로기구 및 변속단기어를 지지하기 위해 사용되던 체결너트(108)를 사용하지 않고, 상기 엔드베어링(7)이 상기 싱크로기구 및 변속단기어를 입력샤프트 및 출력샤프트의 단부에서 지지할 수 있도록 함으로써, 체결너트의 제거에 따른 중량저감 및 변속기 전장축소의 효과를 얻을 수 있다.In addition, the end bearing 7 inputs the synchro mechanism and the shift gear without using the fastening nut 108 conventionally used to support the synchro mechanism and the shift gear at the ends of the input shaft and the output shaft. By being able to support at the ends of the shaft and the output shaft, it is possible to obtain the effect of weight reduction and transmission length reduction due to removal of the fastening nut.

이상과 같이 본 발명에 의하면, 6단 변속기를 구성하면서도 변속기의 전장이 크게 증가하지 않고, 약간의 부품 교체로 5단 변속기와 6단 변속기를 각각 손쉽게 구성할 수 있으며, 아울러 변속기 내부의 윤활성 증대 및 중량 저감의 효과를 동시에 가져올 수 있도록 한다.As described above, according to the present invention, the overall length of the transmission is not greatly increased while the six-speed transmission is configured, and the five-speed transmission and the six-speed transmission can be easily configured by replacing a few parts, and the lubrication of the transmission is increased and It can bring about the effect of weight reduction
