Description

더블 싱크로 콘Double synchro cone

본 발명은 더블 싱크로 콘에 관한 것으로, 특히 자동차의 변속기(transmission)에서 각 변속기어들이 원활하게 서로 물릴 수 있도록 해주므로써 변속감을 향상시켜주는 더블 싱크로 콘(double synchro cone)에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double synchro cone, and more particularly, to a double synchro cone, which improves a feeling of shifting by allowing each gear to smoothly bite each other in a transmission of an automobile.

일반적으로 변속기는 클러치와 추진축 사이에 설치되어 자동차의 주행상태변화에 따른 기관의 회전력을 증대시키거나 감소시키는 역할을 하며, 자동차를 후진시키기 위한 역전장치도 갖추고 있다.In general, the transmission is installed between the clutch and the propulsion shaft serves to increase or decrease the rotational force of the engine according to the change in the driving state of the vehicle, and also has a reverse device for reversing the vehicle.

또한 기관을 조정할 때나 기관을 워엄 업(warm-up)시키기 위해 기관과 구동륜과의 연결을 일정시간 동안 끊어두는 역할도 한다. 이러한 변속기에 각 변속기어들간의 물림이 원활하게 이루어지도록 하기 위한 더블 싱크로 콘이 사용된다.It also serves to disconnect the engine from the drive wheels for a period of time when adjusting the engine or to warm up the engine. In this transmission, a double synchro cone is used to smoothly bite each transmission gear.

제 1도는 종래의 더블 싱크로 콘의 정면도이고, 제 2도는 제 1도 I-I에 따른 단면도이다. 제 1, 제 2도에는 더블 싱크로 콘(10)이 도시되어 있다.FIG. 1 is a front view of a conventional double synchro cone, and FIG. 2 is a sectional view according to FIG. 1 and 2, a double synchro cone 10 is shown.

더블 싱크로 콘(10)은 원통체(12)를 구비하고 있다. 이 원통체(12)는 서로 다른 반경의 제 1외주면(14)과 제 2외주면(16)을 갖고 있으며, 그 중앙에는 소정의 회전축이 삽입될 수 있는 관통공(18)이 형성되어 있다. 이러한 원통체(12)의 제 1 외주면(14)에는 그 외주면을 따라 제 1기어이(20)가 형성되어 있고, 제 2외주면(16)에는 그 외주면을 따라 제 2기어이(22)가 각각 형성되어 있다.The double synchro cone 10 is provided with the cylindrical body 12. The cylindrical body 12 has a first outer circumferential surface 14 and a second outer circumferential surface 16 having different radii, and a through hole 18 into which a predetermined rotating shaft can be inserted is formed in the center thereof. The first gear 20 is formed on the first outer circumferential surface 14 of the cylindrical body 12 along the outer circumferential surface, and the second gear 22 is formed on the second outer circumferential surface 16 along the outer circumferential surface thereof. have.

도시된 바와 같이 원통체(12)의 일측면에 소정 깊이로 4개의 홈(24)이 형성되어 있다. 이 홈(24)은 더블 콘의 러그가 결합되는 부분으로 더블 콘을 지지하여 주기 위한 것이다. 이 홈(24)은 또한 윤활유를 수용하므로써 기어 동기시 윤활이 이루어지도록 하는 역할도 한다.As shown, four grooves 24 are formed on one side of the cylindrical body 12 at a predetermined depth. This groove 24 is a portion to which the lug of the double cone is coupled to support the double cone. The groove 24 also serves to lubricate the gears by accommodating the lubricant.

하지만 제 1, 제 2도에 나타낸 바와 같은 더블 싱크로 콘(10)에서는 홈(24)이 각각 분리되어 있어 윤활유의 이동이 원활치 못하다. 이에 따라 기어 회전시 더블 싱크로 콘(10)의 외주면에 결합되는 싱크로 링이 더블 콘 또는 기어 등에 소착되는 현상이 발생된다.However, in the double synchro cone 10 as shown in Figs. 1 and 2, the grooves 24 are separated from each other, so that the movement of the lubricant is not smooth. Accordingly, a phenomenon in which the synchro ring coupled to the outer circumferential surface of the double synchro cone 10 is squeezed to the double cone or the gear when the gear rotates.

본 발명의 목적은 윤할이 원활히 이루어지도록 하므로써 싱크로 링의 소착 현상을 막을 수 있을 뿐만 아니라 변속감을 좋게 해주는 더블 싱크로 콘을 제공하는 데 있다.An object of the present invention is to provide a double synchro cone not only to prevent the squeeze of the synchro ring by making the lubrication smoothly, but also to improve the feeling of shifting.

제 1도는 종래의 더블 싱크로 콘의 정면도이고,1 is a front view of a conventional double synchro cone,

제 2도는 제 1도 I-I에 따른 단면도,2 is a cross-sectional view according to FIG. 1 I-I,

본 발명의 목적은 소정의 회전축이 삽입될 수 있는 관통공을 구비하고 서로 다른 반경의 제 1외주면과 제 2외주면을 갖는 원통체, 제 1외주면을 따라 형성된 제 1기어이, 제 2외주면을 따라 형성된 제 2기어이, 원통체의 일측면에 소정 깊이로 형성되어 더블 콘의 러그가 결합되는 다수의 홈 및 다수의 홈들을 연결하므로써 상기 다수의 홈들간의 윤활유의 이동을 허용하여 원활한 변속이 이루어질 수 있도록 해주는 윤활유 이동로를 포함하는 것을 특징으로 하는 더블 싱크로 콘에 의해 달성 가능하다.An object of the present invention is a cylindrical body having a through hole into which a predetermined rotating shaft can be inserted and having a first outer circumferential surface and a second outer circumferential surface having different radii, and a first gear formed along the first outer circumferential surface, the second outer circumferential surface being formed along the second outer circumferential surface. The second gear is formed on one side of the cylindrical body to connect a plurality of grooves and a plurality of grooves to which the lug of the double cone is coupled to allow the shift of the lubricating oil between the plurality of grooves so that smooth shifting can be achieved. Is achieved by a double synchro cone.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예를 상세하게 설명하다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

제 3도는 본 발명에 따른 더블 싱크로 콘의 정면도이다. 제 3도에는 본 발명에 따른 더블 싱크로 콘(110)이 도시되어 있다. 이 더블 싱크로 콘(110)은 외주면이 단이지게 형성된 원통체(112)를 구비하고 있다. 이 원통체(112)는 서로 다른 반경의 제 1외주면(114)과 제 2외주면(116)을 갖고 있다. 이 원통체(112)의 중앙에는 소정의 회전축이 삽입될 수 있는 관통공(118)이 형성되어 있다. 이러한 원통체(112)의 제 1외주면(114)에는 그 외주면을 따라 제 1기어이(120)가 형성되어있다. 또한, 제 2외주면(116)에는 그 외주면을 따라 제 2기어이(122)가 각각 형성되어 있다.3 is a front view of a double synchro cone according to the present invention. 3 shows a double synchro cone 110 according to the invention. This double synchro cone 110 is provided with the cylindrical body 112 by which the outer peripheral surface was shortened. The cylindrical body 112 has the 1st outer peripheral surface 114 and the 2nd outer peripheral surface 116 of a different radius. In the center of the cylindrical body 112, a through hole 118 into which a predetermined rotation shaft can be inserted is formed. The first gear 120 is formed on the first outer circumferential surface 114 of the cylindrical body 112 along the outer circumferential surface thereof. In addition, second gears 122 are formed on the second outer circumferential surface 116 along the outer circumferential surface thereof.

제 3도에 나타낸 바와 같이 원통체(112)의 일측면에 일정 각도 간격으로 4개의 홈(124)이 소정 깊이로 형성되어 있다. 이 홈(124)은 더블 콘의 러그가 결합되는 부분으로 더블 콘을 지지하여 주기 위한 것이다. 이 홈(124)들은 윤활유를 수용하므로써 기어 동기시 윤활이 이루어지도록 하는 역할도 한다.As shown in FIG. 3, four grooves 124 are formed at a predetermined depth on one side of the cylindrical body 112 at regular angular intervals. The groove 124 is a portion to which the lug of the double cone is coupled to support the double cone. The grooves 124 also serve to lubricate the gears by accommodating the lubricant.

위에서 설명한 각각의 홈(124)들은 윤활유 이동로(126)를 통해 서로 연결되어 있다. 이 윤활유 이동로(126)는 각각의 홈(124)에 수용되어 있는 윤활유가 홈(124)들 상호간으로 이동될 수 있도록 하므로써 원활한 윤활이 이루어지도록 하기 위한 짓으로, 윤활유가 원활히 이동될 수 있도록 소정 깊이로 형성되어 있어야 된다.Each of the grooves 124 described above is connected to each other through the lubricant movement path 126. The lubricating oil movement path 126 is to allow smooth lubrication by allowing the lubricating oil contained in each of the grooves 124 to be moved between the grooves 124, so that the lubricating oil can be smoothly moved. It must be formed to depth.

즉, 기어 회전시 윤활유 이동로(126)를 따라 윤활유가 순환될 수 있도록 하므로 써, 더블 싱크로 콘(110)의 외주면에 결합되는 싱크로 링이 더블 콘 또는 기어 등에 소착되는 현상을 방지한다. 물론, 윤활유는 더블 싱크로 콘 회전시 원심력에 의해 홈(124)과 윤활유 이동로(126)에서 이탈되지 않는다.That is, the lubricating oil can be circulated along the lubricating oil movement path 126 when the gear rotates, thereby preventing the synchro ring coupled to the outer circumferential surface of the double synchro cone 110 from being caught in the double cone or the gear. Of course, the lubricating oil is not separated from the groove 124 and the lubricating oil moving path 126 by the centrifugal force during the double synchro cone rotation.

이상 설명한 바와 같은 본 발명에 따른 더블 싱크로 콘을 이용하는 경우 윤활유 이동로(126)를 따라 윤활유가 순환되므로 써 싱크로 링이 더블 콘 또는 기어에 소착되지 않을 뿐만 아니라 좋은 변속감을 얻을 수 있다.In the case of using the double synchro cone according to the present invention as described above, since the lubricating oil is circulated along the lubricating oil movement path 126, the synchro ring is not seized on the double cone or gear, and a good shifting feeling can be obtained.
