본 발명은 변속기 구조에 관한 것으로서, 보다 상세하게는 사륜구동차량에서 변속기에 트랜스퍼를 연결함에 있어서, 변속기로부터 트랜스퍼에 이르는 전체적인 길이가 효과적으로 축소될 수 있도록 함으로써, 차량에의 탑재성을 향상시킬 수 있도록 하는 기술에 관한 것이다.The present invention relates to a transmission structure, and more particularly, in connecting a transfer to a transmission in a four-wheel drive vehicle, the overall length from the transmission to the transfer can be effectively reduced, thereby improving the mountability on the vehicle. It is about technology to do.

도 1은 종래의 변속기 구조를 도시한 것으로서, 변속기(500)의 후방인 우측부분에는 어댑터를 통하여 트랜스퍼가 결합되게 된다. 이 경우 변속기(500)로부터 트랜스퍼에 이르는 전체 길이가 매우 길어지게 되어 차량에의 탑재성이 떨어지게 된다.Figure 1 shows a conventional transmission structure, the transfer is coupled to the right side of the rear of the transmission 500 through the adapter. In this case, the total length from the transmission 500 to the transfer becomes very long, resulting in inferior mountability to the vehicle.

차량에의 탑재성을 향상시키기 위해서는 상기 어댑터를 제거함은 물론, 변속기(500) 자체의 길이가 짧아지는 것이 매우 유리하다.In order to improve the mountability in the vehicle, it is very advantageous to shorten the length of the transmission 500 itself as well as removing the adapter.

따라서, 도 1에 도시된 바와 같은 변속기(500)에서 실질적인 변속기구가 설치되지 않은 후방 부분을 제거하고 트랜스퍼를 직접 변속기(500)에 접속하여 결합하는 방안이 강구될 수 있다.Accordingly, a method of removing the rear portion of the transmission 500 as shown in FIG. 1, in which the substantial transmission mechanism is not installed, and connecting the transfer directly to the transmission 500 may be devised.

상기와 같이 변속기(500)의 후방부분을 제거하여 변속기(500) 길이를 축소하고 트랜스퍼를 직접 결합함에 있어서, 상기 도 1의 록킹너트(502)는 변속기(500) 길이를 최소화하는 데에 큰 걸림돌이 된다.As described above, when the rear portion of the transmission 500 is removed to reduce the transmission 500 length and directly couple the transfer, the locking nut 502 of FIG. 1 is a large obstacle to minimizing the transmission 500 length. Becomes

상기 록킹너트(502)는 변속기출력축(504)을 지지베어링(506)에 고정시키는 역할을 하는 것으로서, 충분한 고정력을 확보하기 위해서는 변속기출력축(504) 상에 상기 록킹너트(502)를 체결하기 위한 나사부의 길이가 최소한 30mm이상 필요하여, 록킹너트(502)를 상기와 같은 나사부에 체결하면, 상기 록킹너트(502)는 변속기(500)의 후방측으로 최소한 30mm 이상 돌출되게 되는데, 이러한 록킹너트(502)의 돌출상태는 트랜스퍼 케이스를 변속기(500)에 최대한 접근시켜서 장착함에 걸림돌이 된다.The locking nut 502 serves to fix the transmission output shaft 504 to the support bearing 506, and in order to secure sufficient fixing force, a screw part for fastening the locking nut 502 on the transmission output shaft 504. Since the length of at least 30mm is required, when the locking nut 502 is fastened to the screw, the locking nut 502 protrudes at least 30 mm to the rear side of the transmission 500. Such locking nut 502 The protruding state of the transfer case is an obstacle to the mounting to bring the transfer case as close as possible to the transmission 500.

본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 변속기 후방에서 변속기출력축을 지지베어링에 고정함에 있어서, 변속기 후방으로의 돌출량이 극히 적으면서도 변속기출력축을 지지베어링에 견고하게 고정시킬 수 있도록 함으로써, 트랜스퍼 케이스를 변속기의 후방에 최대한 접근시켜서 장착할 수 있게 하여 변속기로부터 트랜스퍼에 이르는 전체 길이가 매우 짧아져서 차량에의 탑재성이 극대화될 수 있도록 한 변속기 구조를 제공함에 그 목적이 있다.The present invention has been made in order to solve the above problems, in fixing the transmission output shaft to the support bearing in the rear of the transmission, so that the transmission output shaft is fixed firmly to the support bearing while the protrusion amount to the rear of the transmission is extremely small. Accordingly, an object of the present invention is to provide a transmission structure in which the transfer case can be mounted as close to the rear of the transmission as possible so that the total length from the transmission to the transfer can be very short, thereby maximizing the mountability in the vehicle.

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 2 내지 도 4를 참조하면, 본 발명은 변속기출력축(1)에 원주방향으로 형성된 압입홈(3)과; 상기 압입홈(3)에 삽입되고, 측면이 상기 변속기출력축(1)을 변속기케이스에 지지하는 지지베어링(5)에 압착되며, 원주방향을 따라 적어도 두 곳 이상이 절단된 형태의 분할링(7)과; 상기 변속기출력축(1)에 삽입되어 상기 분할링(7)의 외주면을 감싸도록 된 커버링(9)과; 상기 커버링(9)이 상기 분할링(7)을 감싸는 상태를 고정하도록 상기 변속기출력축(1)에 장착되는 스냅링(11)과; 상기 스냅링(11)이 고정되도록 상기 변속기출력축(1)에 형성된 고정홈(13)을 포함하여 구성된다.2 to 4, the present invention is a press-in groove 3 formed in the circumferential direction on the transmission output shaft (1); The dividing ring (7) inserted into the pressing groove (3) and having a side surface pressed against a support bearing (5) for supporting the transmission output shaft (1) to the transmission case, and cut at least two places along the circumferential direction (7). )and; A covering (9) inserted into the transmission output shaft (1) to surround an outer circumferential surface of the split ring (7); A snap ring (11) mounted on the transmission output shaft (1) to fix the covering (9) surrounding the split ring (7); It comprises a fixing groove 13 formed in the transmission output shaft 1 so that the snap ring 11 is fixed.

도 2의 변속기에서는 도 1의 변속기에 비하여 변속기 후방에 실질적인 변속메커니즘이 설치되지 않았던 부위가 제거되었다. 물론, 쉬프트레버 및 쉬프트레버로부터의 조작력을 변속메커니즘으로 전달하는 구조는 종래와 달리 별도로 위치를 변경하여 구비하고 있으며 도면에서는 생략되어 있다.In the transmission of FIG. 2, a portion in which a substantial shift mechanism is not installed at the rear of the transmission is removed as compared to the transmission of FIG. 1. Of course, the structure for transmitting the shift lever and the operating force from the shift lever to the shift mechanism is provided in a different position and is omitted in the drawings.

변속기의 후방에는 트랜스퍼 케이스가 직접 연결되는 것을 트랜스퍼 케이스(15)의 일부를 도시하여 표시하고 있다.A portion of the transfer case 15 is shown and shown that the transfer case is directly connected to the rear of the transmission.

변속기출력축(1)은 종래의 록킹너트 대신에 본 발명에 따른 구조에 의해 지지베어링(5)에 고정되어 있어서, 종래에 록킹너트가 차지하던 부피의 대부분이 제거됨으로써, 트랜스퍼케이스(15)의 위치를 최대한 변속기에 근접시켜서 장착할 수 있게 되었다.The transmission output shaft 1 is fixed to the support bearing 5 by the structure according to the present invention instead of the conventional locking nut, so that most of the volume occupied by the locking nut is removed, thereby positioning the transfer case 15. Can be mounted as close to the transmission as possible.

본 실시예에서 상기 분할링(7)은 도 3에 도시된 바와 같이 원주방향을 따른 단면 형상이 직사각형으로 이루어지고 2개로 양분된 형상을 가지고 있으며, 상기 커버링(9)은 원주방향을 따른 단면 형상이 상기 직사각형 단면의 분할링(7)을 감싸는 ㄱ 자형 단면으로 이루어져 있다.In the present embodiment, the split ring 7 has a rectangular cross-sectional shape along the circumferential direction and is divided into two, as shown in FIG. 3, and the covering 9 has a cross-sectional shape along the circumferential direction. The rectangular cross section consists of an a-shaped cross section surrounding the ring 7.

상기 변속기출력축(1)을 지지베어링(5)에 고정하는 방법은 상기 분할링(7)을 먼저 상기 압입홈(3)에 압입하고, 상기 커버링(9)을 끼운 후, 상기 스냅링(11)을 상기 고정홈(13)에 체결함으로써 완료된다.In the method of fixing the transmission output shaft 1 to the support bearing 5, the split ring 7 is first press-fitted into the press-in groove 3, the covering ring 9 is fitted therein, and then the snap ring 11 is fastened. It is completed by fastening to the fixing groove (13).

상기와 같이 분할링(7)과 커버링(9) 및 스냅링(11)에 의한 구조는, 상기와 같이 비교적 간단하게 조립작업이 이루어질 수 있으며, 종래와 같이 록킹너트와 변속기출력축(1) 사이에 충분한 나사산 확보를 위한 공간을 필요로 하지 않고, 보다 적은 공간에서 변속기출력축(1)을 지지베어링(5)에 견고히 고정시키기 위한 체결력을 확보할 수 있다.As described above, the structure by the split ring 7 and the covering 9 and the snap ring 11 can be assembled relatively simply as described above, and is sufficient between the locking nut and the transmission output shaft 1 as in the prior art. It is possible to secure a fastening force for firmly fixing the transmission output shaft 1 to the support bearing 5 in a smaller space without requiring a space for securing the thread.

상기 변속기출력축(1)을 고정하기 위한 체결력을 확보하기 위해 상기 분할링(7)의 두께를 충분히 확보한다고 하더라도, 종래의 록킹너트를 나사체결하는 방식에 비해서는 그 차지하는 부피가 현저히 작아질 수 있기 때문이다. Even if the thickness of the dividing ring 7 is sufficiently secured to secure the fastening force for fixing the transmission output shaft 1, the volume of the split ring 7 may be significantly smaller than that of the conventional screwing method. Because.

따라서, 변속기의 후방에 트랜스퍼를 최대한 접근시켜서 장착함에 따른 간섭요소를 최대한 배제할 수 있게 되어, 변속기와 트랜스퍼가 컴팩트한 상태로 결합됨으로써, 변속기로부터 트랜스퍼에 이르는 전체 길이가 현저히 축소되어 차량에의 탑재성이 극대화되게 된다.Therefore, the interference element caused by mounting the transfer to the rear of the transmission as close as possible can be eliminated as much as possible. By combining the transmission and the transfer in a compact state, the overall length from the transmission to the transfer is significantly reduced, and the vehicle is mounted on the vehicle. The castle will be maximized.

이상과 같이 본 발명에 의하면, 변속기 후방에서 변속기출력축을 지지베어링에 고정함에 있어서, 변속기 후방으로의 돌출량이 극히 적으면서도 변속기출력축 을 지지베어링에 견고하게 고정시킬 수 있도록 함으로써, 트랜스퍼 케이스를 변속기의 후방에 최대한 접근시켜서 장착할 수 있게 하여 변속기로부터 트랜스퍼에 이르는 전체 길이가 매우 짧아져서 차량에의 탑재성이 극대화될 수 있도록 한다.As described above, according to the present invention, in fixing the transmission output shaft to the support bearing at the rear of the transmission, the transmission case can be firmly fixed to the support bearing while the projection amount toward the rear of the transmission is extremely small, thereby providing the transfer case to the rear of the transmission. The maximum length from the transmission to the transfer is made very short so that the mountability to the vehicle can be maximized.
