통상적으로 자동차용 부변속기는 사륜 구동차량에 있어서 2륜 및 4륜 구동을 선택하는 것으로서, 종래의 부변속기는 제1도에 도시한 바와같이 변속기의 출력축(1)으로부터 동력을 전달받는 구동기어(2)와, 고속 및 저속을 선택하는 하이, 로우 슬리브(3)와, 후륜으로 동력을 전달하는 후륜구동축(4)과, 후륜구동축(4)에 스플라인 결합되어 있는 출력기어(5)와, 이이들축(6)상에 베어링(6a)(6b) 및 스페이서(6c)로 지지되어 상기 구동기어(1) 및 출력기어(5)에 치합 회전하며 사륜구동기어비를 결정하는 아이들기어(7)와, 전륜으로 동력을 전달하는 전류구동축(9)과, 전륜구동축(8)상에 각각 베어링(9a)(10a) 결합되고 상기 아이들기어(7)에 각각 치합하는 하이기어(9)와 로우기어(10), 전륜구동축(8)과 하이기어(9) 또는 로우기어(10)중 선택된 기어를 연결하여 2륜구동 및 4륜구동을 선택하는 4륜구동슬리브(11)가 구비되어 있다.Typically, an auxiliary transmission for a vehicle selects two- and four-wheel drive in a four-wheel drive vehicle, and a conventional auxiliary transmission includes a drive gear that receives power from the output shaft 1 of the transmission as shown in FIG. 2), a high and low sleeve 3 for selecting a high speed and a low speed, a rear wheel drive shaft 4 for transmitting power to the rear wheel, an output gear 5 splined to the rear wheel drive shaft 4, An idle gear 7 supported by the bearings 6a, 6b and the spacer 6c on the field shaft 6 and engaged with the drive gear 1 and the output gear 5 to determine the four-wheel drive gear ratio; The high gear 9 and the low gear 9 are coupled to the current driving shaft 9 for transmitting power to the front wheels, and the bearings 9a and 10a on the front wheel driving shaft 8 and respectively engaged with the idle gears 7. 10), two-wheel drive and four-wheel drive by connecting the gear selected from the front wheel drive shaft (8) and high gear (9) or low gear (10) Four-wheel drive sleeve 11 for selecting the drive is provided.
이러한 종래기술은 4×2H 구동시에는 하이, 로우 슬리브(3)가 구동기어(1)와 후륜구동축(4)의 출력기어(6)를 연결하여 구동기어(1)의 동력이 후륜측으로 직결되어 이루어진다.In this prior art, when driving 4 × 2H, high and low sleeves 3 connect the drive gear 1 and the output gear 6 of the rear wheel drive shaft 4 so that the power of the drive gear 1 is directly connected to the rear wheel side. Is done.
그리고 4×4H 구동시에는 하이, 로우 슬리브(3)가 구동기어(1)와 후륜구동축(4)을 연결하여 구동기어(1)의 동력이 후륜측으로 연결됨과 동시에 4륜구동슬리브(11)가 하이기어(9)와 전륜구동축(8)을 연결하여 구동기어(1)의 동력이 아이들기어(7) 및 하이기어(9)를 통해 전륜 구동축(8)을 낮은 감속비로 회전시켜 이루게된다.In the case of 4 × 4H driving, the high and low sleeves 3 connect the drive gear 1 and the rear wheel drive shaft 4 so that the power of the drive gear 1 is connected to the rear wheel side and the four wheel drive sleeve 11 is high. By connecting the gear 9 and the front wheel drive shaft 8, the power of the drive gear 1 is achieved by rotating the front wheel drive shaft 8 at a low reduction ratio through the idle gear 7 and the high gear 9.
한편 4×4L 구동시에는 역시 하이, 로우 슬리브(3)가 구동기어(1)와 후륜구동축(4)을 연결하여 구동기어(1)의 동력이 후륜측으로 연결되어 있는 상태에서 4륜구동슬리브(11)가 로우기어(10)와 전륜구동축(4)을 연결하여 구동기어(1)의 동력이 아이들기어(7) 및 로우기어(10)를 통해 전륜구동축(4)을 비교적 큰 감속비로 회전시켜 이루게 되다.On the other hand, in the case of 4 × 4L driving, the high and low sleeves 3 connect the drive gear 1 and the rear wheel drive shaft 4 so that the power of the drive gear 1 is connected to the rear wheel side. ) Connects the low gear 10 and the front wheel drive shaft 4 so that the power of the drive gear 1 rotates the front wheel drive shaft 4 at a relatively large reduction ratio through the idle gear 7 and the low gear 10. become.
그러나 이와같은 구성 및 작용을 갖는 종래기술은 다수의 기어로써 구성되어 있어 조립성이 떨어지고 있다. 즉 구동기어(1) 및 즉 구동기어(1) 및 출력기어(6), 아이들기어(7), 하이기어(9)와 로우기어(10)의 5종의 기어를 구비하여야 하므로 조립에 어려움이 있었으며 중량이 무거워지게되어 조립성을 더욱 열악하게 함은 물론 다종의 기어로 인한 제조원가의 상승요인으로 작용하고 있었다.However, the prior art having such a configuration and action is composed of a plurality of gears, and assembling is inferior. In other words, the drive gear 1 and the drive gear 1 and the output gear 6, the idle gear 7, the high gear 9 and the five gears of the low gear 10 should be provided, which is difficult to assemble. As the weight became heavy, the assembly was worse and the manufacturing cost was increased due to various gears.
그리고 상기와 같이 5종의 기어가 항시 치합하여 회전을 이루고 있으므로 작동시 치음(齒音)으로 인한 부변속기내의 소음이 크게되는 문제 또한 갖고 있었다.In addition, since the five gears are always engaged to rotate as described above, the noise in the sub-transmission due to the tooth decay during operation also increases.
이에 본 발명은 상기와 같은 제반 문제를 감안하여 안출된 것으로서, 그 목적은 구조를 간단히하여 조립성을 향상시킴과 동시에 소음을 감소시킬 수 있는 자동차용 부변속기의 동력전달 장치를 제공함에 있다.Accordingly, the present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a power transmission device for an auxiliary transmission for an automobile which can simplify the structure to improve assembly and at the same time reduce noise.

이하 본 발명의 바람직한 실시예를 첨부 도면에 의거하여 좀 더 구체적으로 설명하면 다음과 같다(종래와 동일 구성은 그 부호를 동일하게 설명한다), 제2도에는 본 발명의 구성이 도시되어 있는데, 이에 따르면 본 발명은 변속기로부터 동력을 전달받는 입력축기어(20)가 구비되고, 입력축기어(20)로부터 선택적으로 동력을 전달받는 출력축기어(30)가 구비되어 있다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings (the same configuration as in the prior art describes the same reference numerals), and FIG. Accordingly, the present invention is provided with an input shaft gear 20 that receives power from the transmission, and is provided with an output shaft gear 30 that selectively receives power from the input shaft gear 20.

또한 변속포크(52)에 의해 이동하며 상기 출력축기어(30)를 입력축기어(20) 또는 출력측기어(32)중 선택된 하나의 기어에 연결하는 하이, 로우 슬리브(50)가 구비되고, 상기 출력축기어(30)상에 베어링지지되는 스프로켓(60)이 구비되어 있다.In addition, a high and low sleeve 50, which is moved by the shifting fork 52 and connects the output shaft gear 30 to one gear selected from the input shaft gear 20 or the output side gear 32, is provided. A sprocket 60 which is bearing-supported on 30 is provided.
한편 상기 스프로켓(60) 측단의 출력축기어(30)상에는 그 출력축기어(30)상에는 그 출력측기어(30)에 스플라인결합되는 클러치허브(34)가 구비되고, 변속포크(72)에 의해 클러치허브(34)와 스프로켓(60)을 선택적으로 연결하는 4륜선택슬리브(70)가 구비되어 있다.On the other hand, on the output shaft gear 30 of the sprocket 60 side end is provided with a clutch hub 34 is splined to the output side gear 30 on the output shaft gear 30, the clutch hub ( Four-wheel selection sleeve 70 for selectively connecting 34 and the sprocket 60 is provided.
그리고, 상기 스프로켓(60)과 체인(90)연결되는 스프로켓(82)이 형성된 전륜구동축(80)이 구비되어 있다. 상기 체인은 사일런트체인을 사용함에 바람직하다.Then, the front wheel drive shaft 80 is provided with a sprocket 82 is connected to the sprocket 60 and the chain 90. The chain is preferable to use a silent chain.
이와같은 구성을 갖는 본 발명은 4×2H 구동시에는 하이, 로우 슬리브(50)가 입축기어(20)와 출력축기어(30)를 연결하여 입력축기어(20)의 동력이 후륜측으로 적절되어 이루어진다. 이때 카운트축깅(40)와 출력기어(32) 그리고 스프로켓(60)은 공회전을 이루게 된다.In the present invention having such a configuration, the high and low sleeves 50 are connected to the vertical gear 20 and the output shaft gear 30 when driving the 4 × 2H, so that the power of the input shaft gear 20 is appropriate to the rear wheel side. At this time, the counting shaft 40, the output gear 32 and the sprocket 60 is made of idling.
그리고 4×4H 구동시에는 하이, 로우 슬리브(50)가 입력축기어(20)와 출력축기어(30)를 연결하여 입력축 기어(20)의 동력이 후륜측으로 직결됨과 동시에 4륜선택 슬리브(70)간 클러치허브(34)와 스프로켓(60)을 연결하여 체인(90)을 통해 전륜구동축(80)을 구동시켜 낮은 감속비로 회전시켜 고속회전을 이루게 된다.In the case of 4 × 4H driving, the high and low sleeves 50 connect the input shaft gear 20 and the output shaft gear 30 so that the power of the input shaft gear 20 is directly connected to the rear wheel side and at the same time between the four wheel selection sleeves 70. The clutch hub 34 and the sprocket 60 are connected to drive the front wheel drive shaft 80 through the chain 90 to rotate at a low reduction ratio to achieve high speed rotation.
한편 4×4H 구동시에는 하이, 로우 슬리브(50)가 출력축기어(30)와 출력기어(32)를 연결하여 구동기어(20)의 동력이 카운트축기어(40) 및 출력기어(32)를 통해 출력축기어(30)에 전달되어 후륜을 구동함과 동시에 4륜 선택슬리브(70)가 클러치허브(34)와 스프로켓(60)을 연결하여 체인(90)을 통해 전륜구동축(80)을 구동하게 되므로 비교적 큰 감속비로 회전시켜 전륜구동축(80)이 저속회전을 이루게 된다.On the other hand, when driving 4 × 4H, the high and low sleeves 50 connect the output shaft gear 30 and the output gear 32 so that the power of the drive gear 20 drives the count shaft gear 40 and the output gear 32. It is transmitted to the output shaft gear 30 to drive the rear wheel and at the same time the four-wheel selection sleeve 70 connects the clutch hub 34 and the sprocket 60 to drive the front wheel drive shaft 80 through the chain 90. Therefore, by rotating at a relatively large reduction ratio, the front wheel drive shaft 80 achieves a low speed rotation.
또한, 일본 특개평 2-151526호와 같은 변속기로부터 전동 체인을 거쳐 출력측으로 동력을 전달되도록 구성된 것에 있어서는 입력기어에 삽입되어 운동력을 전달하는 입력축이 차축과 운동게이즈와의 연결상태가 미흡하게 되어 그 운동력이 완전한 상태로 전달될 수 없어 운동력이 손실되는 결함과 출력축상에 베어링 지지상태 및 입력축으로 구동력으로 전달하게 되는 클러치허브 및 하이, 로우 슬리브 등의 설치상태가 복잡한 구조로 이루어지고 있어서 조립공수의 어려움으로 작업성이 불량하게 되는 문제점이 있었다.In addition, in the configuration configured to transmit power from the transmission such as Japanese Patent Laid-Open No. 2-151526 to the output side via the electric chain, the input shaft inserted into the input gear to transmit the kinetic force is insufficient in connection with the axle and the motion gauge. It is composed of complex structure that has the defects of losing the kinetic force because the kinetic force cannot be transmitted in perfect state and the installation state of the clutch hub, high and low sleeve, etc. There was a problem of poor workability due to difficulty.
상술한 바와 같이 본 발명에 따른 자동차용 부변속기의 출력축기어와 전륜구동축을 체인전동하므로써 종래와 같은 아이들기어를 필요로 하지않게 되어 부품의 간소화로 조립성을 향상시킬 수 있게되고, 기어끼리 항시치합하는 부분을 감소시켜 소음을 저감시킬 수 있게 되었다. 또한 종래와 같이 호빙과 세이빙을 필요로하는 기어를 다수개 필요하는 것에 비해 적은수의 기어 및 호빙으로만 제작가능한 스프로켓으로 전동을 이루고 있으므으로 가공생산성 또한 향상 시킬 수 있는 효과를 갖게 되는 것이다.As described above, the chain drive of the output shaft gear and the front wheel drive shaft of the secondary transmission for a vehicle according to the present invention does not require the idle gear as in the prior art, thereby improving the assemblability by simplifying parts, and the gears are always It is possible to reduce noise by reducing the sum of the parts. In addition, compared to the need for a number of gears that require hobbing and shaving as in the prior art, because the transmission is made of a small number of gears and the sprocket can be produced only by hobbing, it will have the effect of improving the processing productivity.
