Abstract

PURPOSE: The synchronizer of a manual transmission is provided to prevent oil to remain on a friction surface by discharging the oil through oil discharge holes when executing a synchronization operation by the friction of a synchronizer ring and a corn part. CONSTITUTION: The synchronizer of a manual transmission comprises an herb(220), a sleeve(230), a key(240), a clutch gear(250), and a synchronizer ring(260). The herb is combined in the spline(210) of a principal axis(200). The sleeve is combined to be possible to move from the outer circumference of the herb to an axial direction. The key is located between the herb and the sleeve and mutually fixes the herb and the sleeve. The clutch gear is integrally combined with a speed gear(S) which is combined with the principal axis. The clutch gear comprises a corn part(255) which synchronizes the speed of rotation of the speed gear and the sleeve. The synchronizer ring is located in the outer side of the corn part and is synchronized by friction contact with the corn part when changing a speed.

따라서, 본 명세서에 기재된 실시예와 도면에 도시된 구성은 본 발명의 가장 바람직한 일 실시예에 불과할 뿐이고, 본 발명의 기술적 사상을 모두 대변하는 것은 아니므로, 본 출원시점에 있어서 이들은 대체할 수 있는 다양한 균등물과 변형예들이 있을 수 있음을 이해하여야 한다.Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention, and not all of the technical ideas of the present invention are described. Therefore, It should be understood that various equivalents and modifications may be present.

도 2에 도시된 바와 같이, 본 발명의 일 실시예에 따른 수동변속기의 동기장치는 주축(200)의 스플라인(210)에 결합되는 허브(220)와, 상기 허브(220)의 외주면에서 축방향으로 이동가능하도록 결합된 슬리브(230)와, 상부에 돌기부(245)가 형성되고 상기 허브(220)와 상기 슬리브(230) 사이에 마련되어 상기 허브(220)와 상기 슬리브(230)를 상호고정시키는 키(240)와, 상기 슬리브(230)에 삽입되되 상기 주축(200)과 결합되는 스피드기어(S)와 일체로 결합되어 상기 슬리브(230)와 스피드기어(S)의 회전속도를 동기화시키는 콘부(255)가 구비된 클러치기어(250) 및 상기 콘부(255)의 외측면에 위치하여 변속시 상기 콘부(255)와의 마찰접촉에 의해 동기화되는 싱크로나이저링(260)을 포함하여 구성된다.As shown in FIG. 2, a synchronization device of a manual transmission according to an embodiment of the present invention includes a hub 220 coupled to a spline 210 of a main shaft 200, and an axial direction at an outer circumferential surface of the hub 220. A sleeve 230 and a protrusion 245 are formed at an upper portion thereof, and are provided between the hub 220 and the sleeve 230 so as to be mutually fixed to the hub 220 and the sleeve 230. Cone part inserted into the key 240 and the sleeve 230, integrally coupled with the speed gear (S) coupled to the main shaft 200 to synchronize the rotational speed of the sleeve 230 and the speed gear (S) The clutch gear 250 having the 255 and the synchronizer ring 260 positioned on the outer surface of the cone part 255 are synchronized by frictional contact with the cone part 255 during shifting.

여기서, 상기 스피드기어(S)는 상기 주축(200) 상에 회전가능하도록 결합된다.Here, the speed gear (S) is rotatably coupled to the main shaft (200).

상기한 클러치기어(250)는 스피드기어(S)의 측면에 용접 고정되어 상기 슬리이브(230)와 동기 치합되면서 스피드기어(S)와 슬리브(230) 사이에 동력 전달이 이루어지도록 구비된다.The clutch gear 250 is welded and fixed to the side of the speed gear S, and is synchronously engaged with the sleeve 230 to provide power transmission between the speed gear S and the sleeve 230.

또한, 상기 콘부(255)에는 도 3에 도시된 바와 같이, 상기 싱크로나이저링(260)과의 접촉면과 연통되는 오일배출홀(255a)이 복수로 관통 형성된다.In addition, as shown in FIG. 3, the cone part 255 is formed with a plurality of oil discharge holes 255a communicating with the contact surface of the synchronizer ring 260.

이와 같이 구성되는 본 발명의 수동변속기의 동기장치의 작동은 다음과 같다.Operation of the synchronization device of the manual transmission of the present invention configured as described above is as follows.

운전자가 변속을 하기 위해 변속레버를 조작하게 되면, 상기 슬리브(230)가 이동하게 되고, 이에 따라 상기 슬리브(230)의 내부 스플라인 홈부에 물려 있는 상기 키(240)의 돌기부(245)를 밀어서 상기 싱크로나이저링(260)을 밀게 된다.When the driver manipulates the shift lever to shift, the sleeve 230 moves, thereby pushing the protrusion 245 of the key 240 bited into the inner spline groove of the sleeve 230. Push the synchronizer ring 260.

이와 함께 상기 슬리브(230)가 계속 이동됨에 따라 상기 싱크로나이저링(260)이 상기 콘부(255)와 밀착되면서 상기 스피드기어(S)가 회전력을 전달받기 시작한다.In addition, as the sleeve 230 continues to move, the synchronizer ring 260 comes into close contact with the cone part 255 and the speed gear S starts to receive a rotational force.

이러한 작용으로 상기 스피드기어(S)와 상기 싱크로나이저링(260)이 동기되면, 상기 싱크로나이저링(260)은 상기 슬리브(230)의 내부 스플라인으로 들어가고, 상기 슬리브(230)의 스플라인과 상기 클러치기어(250)의 스플라인이 록킹되어 동력 전달이 이루어진다.When the speed gear S and the synchronizer ring 260 are synchronized with each other, the synchronizer ring 260 enters the inner spline of the sleeve 230, and the spline of the sleeve 230 and the clutch are synchronized with each other. The spline of the gear 250 is locked to achieve power transmission.

한편, 본 발명의 수동변속기의 동기장치는 겨울철 저온 변속시 오일의 냉각에 의한 점도상승을 감안하여 싱크로나이저링(260)과 대응되는 클러치기어(250)의 콘부(255)에 오일배출홀(255a)이 복수로 형성되어 있다.On the other hand, the synchronous device of the manual transmission of the present invention in consideration of the increase in viscosity due to the cooling of the oil at low temperature shift in winter, the oil discharge hole 255a in the cone portion 255 of the clutch gear 250 corresponding to the synchronizer ring 260 ) Are formed in plural.

따라서, 싱크로나이저링(260)과 콘부(255)의 마찰에 의한 동기작용시 그 마찰면에 오일이 잔류되지 않고, 오일배출홀(255a)들을 통해 오일이 빠져나감으로써 동기작용이 원활하게 이루어질 수 있어서 사용자는 변속을 용이하게 실시할 수 있다.Accordingly, when the synchronizing action of the synchronizer ring 260 and the cone portion 255 is caused by friction, oil does not remain on the friction surface, and the oil flows out through the oil discharge holes 255a to smoothly synchronize the oil. Therefore, the user can easily shift.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나 이에 한정되지 않으며, 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술 사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형 가능함은 물론이다.As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and it should be understood by those of ordinary skill in the art to which the present invention relates, Of course, various modifications and variations can be made within the equivalent range.
