본 고안은 차량용 동기물림식 변속기의 콘클러치고정구조에 관한 것으로, 특히 기어에 고정되는 콘클러치의 고정구조를 개량하여 생산비가 절감되고, 생산성이 향상되도록 된 차량용 동기물림식변속기의 콘클러치고정구조에 관한 것이다.The present invention relates to a cone clutch fixing structure of a synchronous clutch transmission for a vehicle, and in particular, by improving the fixing structure of the cone clutch fixed to a gear, the production cost is reduced and productivity is improved. It is about.

일반적으로 동기물림식변속기에서 사용되는 콘클러치는 클러치(도시되어 있지 않음)작용에 의해 물리는 기어(101)를 상대기어(도시되어 있지 않음)와 같은 속도(동기작용)로 하여 주도록 되어 있다.In general, the cone clutch used in the synchronous buckling transmission is configured to cause the gear 101 to be bitten by the clutch (not shown) action at the same speed (synchronization) as the counterpart gear (not shown).

제3도는 동기물림식 변속기에서 콘클러치의 고정구조인데 도시된 바와 같이, 주축(도시되어 있지 않음)에 연결된 드라이브기어(101)에 콘클러치(105)가 고정되는바, 상기 드라이브기어(101)에는 외주면에 기어(104)를 형성한 몸체(102)와 외주면에 스플라인(103A)을 형성한 단차진 돌출부(103)가 형성되고 또한, 상기 드라이브기어(101)에 고정되는 콘클러치(105)에는 외주면에 기어(108)를 형성한 몸체(106)와 이로부터 단차져 경사진 돌출부(107)가 형성되는 한편, 상기 콘클러치(105)의 내경에는 스플라인(108A)이 형성되어 드라이브기어(101)의 돌출부(103)에 형성된 스플라인(103A)과 결합된 다음 결합부위 둘레를 용접하여 고정시키게 된다.3 is a fixed structure of the cone clutch in the synchronous-type transmission, as shown, the cone clutch 105 is fixed to the drive gear 101 connected to the main shaft (not shown), the drive gear 101 In the body 102 having the gear 104 formed on the outer circumferential surface and the stepped protrusion 103 having the spline 103A formed on the outer circumferential surface thereof, the cone clutch 105 fixed to the drive gear 101 is formed. A body 106 having a gear 108 formed on its outer circumference and a stepped protrusion 107 stepped therefrom are formed, while a spline 108A is formed at the inner diameter of the cone clutch 105 to form a drive gear 101. It is coupled to the spline 103A formed on the protrusion 103 of and then fixed by welding around the coupling portion.

따라서, 드라이브기어(101)와 콘클러치(105)가 스플라인(103A,108A)에 의해 상호 결합되어 고속회전시 회전방향으로 뒤틀리는 것을 방지하는 한편, 결합부위 둘레가 용접되어 축방향으로 이탈되는 것을 방지하면서 동기작용을 수행하게 된다.Accordingly, the drive gear 101 and the cone clutch 105 are coupled to each other by the splines 103A and 108A to prevent the drive gear 101 from twisting in the rotational direction at high speed, while preventing the circumference of the coupling portion from being welded and deviating in the axial direction. It will perform the synchronization.

그러나 이와같이 드라이브기어(101)와 콘클러치(105)가 스플라인(103A,108A)에 의해 결합되게 되면, 상기 스플라인(103A,108A)의 가공이 용이하지 않을뿐만 아니라, 이에따른 생산비가 상승되는 등의 문제가 있었다.However, when the drive gear 101 and the cone clutch 105 are coupled to each other by the splines 103A and 108A, the processing of the splines 103A and 108A is not easy and the production cost is increased accordingly. There was a problem.

제4도는 이와같은 문제점을 보완하기 위해 사용되는 다른 실시예인데 도시된 바와 같이, 주축(도시되어 있지 않음)에 연결되는 드라이브기어(101)가 콘클러치(105)를 포함한 일체형으로 형성되는바, 상기 드라이브기어(101)에는 외주면에 기어(104)를 형성한 몸체(102)가 일정한 폭으로 형성되면서 콘클러치(105)의 몸체(106)를 형성하는데 이때, 상기 드라이브기어(101)의 몸체(102)와 콘클러치(105)의 몸체(106) 사이에는 틈새(110)가 구비되어 드라이브기어(101)의 기어(104)가공시 공구에 의한 간섭을 받지 않도록 하는 한편, 상기 콘클러치(105)의 몸체(106)에는 드라이브기어(101)의 몸체(102)의 외경보다 크면서 기어(108)가 형성되고, 상기 몸체(106)에서부터 선단쪽으로 약간 경사지게 돌출부(107)가 형성되어 있다.4 is another embodiment used to supplement this problem, as shown, the drive gear 101 connected to the main shaft (not shown) is formed integrally including the cone clutch 105, In the drive gear 101, a body 102 having a gear 104 formed on an outer circumferential surface thereof has a predetermined width, and forms a body 106 of the cone clutch 105. In this case, the body of the drive gear 101 ( The clearance 110 is provided between the 102 and the body 106 of the cone clutch 105 to prevent the gear 104 of the drive gear 101 from being interfered with by the tool while machining the cone clutch 105. The body 106 of the drive gear 101 is larger than the outer diameter of the body 102 of the gear 108 is formed, the protrusion 107 is formed to be slightly inclined toward the tip from the body 106.

따라서, 드라이브기어(101)와 콘클러치(105)가 틈새(110)를 사이에 두고 좌/우 일체형으로 형성되어 동기작용을 수행하게 된다.Accordingly, the drive gear 101 and the cone clutch 105 are formed integrally with the left and right with the clearance 110 therebetween to perform the synchronous action.

그러나 이와같이 드라이브기어(101)와 콘클러치(105)가 틈새(110)를 사이에 두고 좌/우 일체형으로 형성되게 되면 기어(104)의 가공시 공구의 간섭에 의한 문제를 해소하기 위해 상기 드라이브기어(101)와 콘클러치(105)사이에 틈새(110)가 형성되어야만 하므로, 트랜스미션의 전체 설계에 많은 제약을 초래하는 등의 문제가 있었다.However, if the drive gear 101 and the cone clutch 105 are formed integrally with the left and right with the clearance 110 therebetween, the drive gear may be solved to solve the problem caused by the interference of the tool during the machining of the gear 104. Since the clearance 110 must be formed between the 101 and the cone clutch 105, there existed a problem of causing a lot of restrictions in the whole design of a transmission.

이에 본 고안은 상기와 같은 제반문제를 해소하기 위하여 안출된 것으로, 드라이브기어아 콘클러치의 결합구조를 개량하여 제작비를 절감시키고, 트랜스미션의 전체 설계에 대한 제약을 해소하도록 된 차량용 동기물림식변속기의 콘클러치고정구조를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, and improves the coupling structure of the drive gear cone clutch to reduce the manufacturing cost and to remove the constraints on the overall design of the transmission. The purpose is to provide a cone clutch fixing structure.

상기와 같은 목적을 달성하기 위한 본 고안은 드라이브기어의 돌출부 외경과 콘클러치의 내경에 서너개의 키홈이 구비되어 고정키를 압입한다음 결합부위의 둘레를 따라 용접시켜 상호 고정되는 구조로 되어 있다.The present invention for achieving the above object is provided with three or four key grooves are provided in the outer diameter of the protrusion of the drive gear and the inner diameter of the cone clutch is pressed into the fixing key and welded along the circumference of the coupling portion is fixed to each other.

이하 본 고안을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 콘클러치가 드라이브기어에 결합된 부분단면도인데 도시된 바와 같이 주축(도시되어 있지 않음)에 연결되는 드라이브기어(1)에 콘클러치(5)가 고정 되는 바, 상기 드라이브기어(1)에는 외주면에 기어(4)를 형성한 몸체(2)와 외주면에 서너개의 키홈(10,11)이 구비된 단차진 돌출부(3)가 형성되는 한편, 상기 돌출부(3)의 선단부위는 용접을 용이하게 하도록 단차져 있게 된다.1 is a partial cross-sectional view in which the cone clutch is coupled to the drive gear, and as shown, the cone clutch 5 is fixed to the drive gear 1 connected to the main shaft (not shown). In the outer circumferential surface is formed a body 2 and a stepped protrusion 3 having three or four key grooves 10 and 11 on the outer circumferential surface, while the tip portion of the protrusion 3 is welded. Stepped to facilitate.

또한, 상기 드라이브기어(1)에 고정되는 콘클러치(5)에는 외주면에 기어(8)를 형성한 몸체(6)와 이로부터 단차져 경사진 돌출부(7)가 형성되는 한편, 상기 콘클러치(5)의 내경에는 따라 서너개의 키상단홈(11)이 형성되어 드라이브기어(1)의 돌출부(3)에 형성된 키하단홈(10)과 일치되게 결합하여 고정키(9)를 압입시킨 다음 결합부위 둘레를 용접하여 고정시키게 된다.In addition, the cone clutch 5 fixed to the drive gear 1 is formed with a body 6 having a gear 8 formed on an outer circumferential surface thereof, and a protrusion 7 inclined therefrom, while the cone clutch ( In the inner diameter of 5), three or four key upper grooves 11 are formed so as to coincide with the lower key groove 10 formed in the protrusion 3 of the drive gear 1 to press-fit the fixing key 9, and then The perimeter of the site is fixed by welding.

따라서, 드라이브기어(1)와 콘클러치(5)가 키홈(10,11)에 삽입된 고정키(9)를 매개로 상호 결합되어 고속회전시 회전방향으로 뒤틀리는 것을 방지하는 한편, 결합부위 바깥둘레가 용접되어 측방향으로 이탈되는 것을 방지하면서 동기작용을 수행하게 된다.Accordingly, the drive gear 1 and the cone clutch 5 are coupled to each other through the fixing key 9 inserted into the key grooves 10 and 11 to prevent the drive gear 1 from twisting in the rotational direction at the high speed rotation, and the outer circumference of the engaging portion. Is welded to perform synchronous action while preventing lateral deviation.

이상 설명한 바와 같이 드리이브기어와 콘클러치에 형성된 서너개의 키홈에 고정키가 압입된다음 결합부위 둘레를 용접하게되어 트랜스미션의 전체설계에 대한 제한을 받지않을뿐만 아니라, 스플라인의 가공에 비해 제작비를 절감시키게 되는 효과가 있게 된다.As described above, the fixing key is pressed into the three or four key grooves formed in the drive gear and the cone clutch, and then welded around the coupling portion, thereby not limiting the overall design of the transmission and reducing the manufacturing cost compared to the processing of the spline. Become effective.
