Description

수동변속기의 동기화 장치Synchronizer of Manual Transmission

본 고안은 자동차용 수동변속기의 동기화 장치에 관한 것으로, 보다 구체적으로는, 싱크로나이저 링과 단기어의 마찰면이 확대되어 변속성능을 향상시킬 수 있을 뿐만 아니라 내구성도 향상된 수동변속기의 동기화 장치에 관한 것이다.The present invention relates to a synchronization device of a manual transmission for a vehicle, and more particularly, to a synchronization device of a manual transmission, in which a frictional surface of a synchronizer ring and a short-term word is enlarged to improve shift performance and improve durability. will be.

변속기(Transmission)은 클러치와 추진축(Propeller Shaft) 사이에 설치되어 자동차의 주행상태 변화에 따른 기관의 회전력을 증대시키거나 감소시키는 역할을 하며 자동차를 후진시키기 위한 역전장치도 갖추고 있다.Transmission is installed between the clutch and the propeller shaft 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 reversing device for reversing the vehicle.

이러한 변속기로는 그 변속의 형식에 따라 섭동기어식(Sliding gear type)과 상기 치합식(Constant-mesh type 또는 Dog clutch type) 그리고 동기치합식(Syncro-mesh type)으로 구분된다.Such transmissions are classified into a sliding gear type, a coupling type (Constant-mesh type or a dog clutch type), and a synchronization type (Syncro-mesh type) according to the type of the transmission.

이중 최근 가장 많이 사용되고 있는 것을 동기 치합식이다.Among them, the most frequently used is a synchronous coupling type.

동기 동기 치합식은 주축과 부축의 기어를 최초부터 맞물림을 시켜 놓고(상시교합), 코어부이나 싱크로나이저 링 등을 클러치를 사용하여 기어의 회전을 거의 일치시킨 후, 슬리브에 의하여 상호 결합시켜 회전을 전달시키는 방식을, 본 고안도 이러한 동기 치합식 변속기구에 설치되는 수동변속기의 동기화 장치에 관한 것이다.Synchronous synchronous meshing is to engage the gears of the main shaft and the sub-shafts from the beginning (always on), and use the clutches to closely match the rotation of the gears by using the clutch of the core part or synchronizer ring, and then engage each other by the sleeve to rotate the gears. The present invention also relates to a synchronization device of a manual transmission installed in such a synchronous engagement transmission mechanism.

첨부된 도면의 제1도는 종래의 수동변속기의 동기화 장치의 구조를 보인 단면도이다.1 is a cross-sectional view showing the structure of a conventional synchronization device of a manual transmission.

도시된 바와 같이, 동기화 장치는 주축상에서 자유로이 회전하는 단기어(shift gear)(1)의 코어부(1a)와 싱크로나이저 링(synchronizer ring)(2)을 클러치(미도시)를 사용하여 밀착시켜 이들 사이의 마찰력으로 기어의 회전을 거의 일치시킨 후, 슬리이브(미도시)에 의하여 상호결합시켜 회전력을 전달하도록 한 것이다.As shown, the synchronizing device uses a clutch (not shown) to bring the synchronizer ring 2 and the core 1a of the shift gear 1 freely rotated on the main shaft. The rotation of the gears is substantially matched by the friction force between them, and then coupled to each other by a sleeve (not shown) to transmit the rotational force.

이와 같은 동기화 장치에 있어서, 그 변속 성능은 코어부(1a)와 싱크로나이저 링(2)의 마찰면적이 좌우하게 된다.In such a synchronization device, the shift performance depends on the friction area between the core portion 1a and the synchronizer ring 2.

그러나, 앞서 예로든 종래의 수동변속기의 동기화 장치는 제1도에서 알 수 있는 바와 같이, 코어부(1a)와 싱크로나이저 링(2)이 테이퍼 형태로 만나 그 접촉되는 면적이 적기 때문에 변속성능이 좋지 못할 뿐만 아니라, 마찰력이 집중되어 내구성도 현저히 떨어지는 등의 문제점을 가지고 있었다.However, the synchronization device of the conventional manual transmission, as exemplified above, has a shifting performance because the core part 1a and the synchronizer ring 2 are tapered in contact with each other so that the contact area is small. Not only was it not good, but the friction was concentrated, and the durability was also significantly reduced.

본 고안은 상술한 바와 같은 종래의 수동변속기의 동기화 장치가 가진 문제점이 해소된 것으로, 단기어의 코어부와 싱크로나이저 링 사이의 마찰면적이 확대되고, 또 이들에 각각 면접촉하여 마찰면적을 확대시키는 마찰링이 신설되어, 변속성능을 향상시킬 수 있을 뿐만 아니라 내구성도 현저히 증가시킬 수 있는 수동변속기의 동기화 장치를 제공하는 것을 목적으로 한다.The present invention solves the problems of the conventional synchronizing apparatus of the manual transmission as described above. The friction area between the core portion of the short term and the synchronizer ring is enlarged, and the friction area is increased by the surface contact with each of them. It is an object of the present invention to provide a synchronizing device for a manual transmission, in which a friction ring is added, which can not only improve shift performance but also significantly increase durability.

제1도는 종래의 수동변속기의 동기화 장치 단면도.1 is a cross-sectional view of a synchronization device of a conventional manual transmission.

제2도는 본 고안의 수동변속기의 동기화 장치 단면도.2 is a cross-sectional view of a synchronization device of a manual transmission of the present invention.

상기한 바와 같은 목적을 가지는 본 고안의 구성 및 작용을 첨부된 도면에 제시된 바람직한 일 실시예를 통하여 구체적으로 설명한다.The configuration and operation of the present invention having the purpose as described above will be described in detail with reference to the preferred embodiment shown in the accompanying drawings.

참고로, 본 실시예를 설명함에 있어서, 앞서의 예로든 종래의 기술의 구성과 도일한 구조와 기능을 하는 본 실시예의 구성에 대해서는 동일부호를 설명하였음을 밝혀둔다.For reference, in describing the present embodiment, the same reference numerals are used to describe the configuration of the present embodiment having the same structure and function as those of the prior art.

첨부된 도면의 제1도는 본 고안의 일 실시예에 의한 수동변속기의 동기화 장치의 구조를 보인 단면도이다.1 is a cross-sectional view showing the structure of a synchronization device of a manual transmission according to an embodiment of the present invention.

도시된 바와 같이 본 실시예의 수동변속기의 동기화 장치는 외주에 원추형의 마찰면을 가지는 단기어(1)의 코어부(1a)와, 이 코어부(1a)에 면접촉되는 마찰면을 내주부에 가지는 싱크로나이저 링(2)을 포함하여 이루어진다.As shown, the synchronization device of the manual transmission according to the present embodiment has a core portion 1a of the short term gear 1 having a conical friction surface on its outer circumference, and a friction surface in surface contact with the core portion 1a on its inner circumference. The branch comprises a synchronizer ring 2.

상기 코어부(1a)는 단기어(1)에 일체화된 것으로, 외주가 원추형으로 성형되어 싱크로나이저 링(2)의 내주에 면접촉되는 것으로, 종래와 달리 축단부에 또하나의 마찰면이 형성된다.The core portion 1a is integrated into the short term fish 1, and the outer circumference is formed into a conical shape and is in surface contact with the inner circumference of the synchronizer ring 2. Unlike the related art, another friction surface is formed at the shaft end. do.

싱크로나이저 링(2)은 상기 코어부(1a)의 외주부에 끼워져 그 내주면이 코어부(1a)의 외주와 면접촉되어 마찰되는 것으로, 본 실시예에서는 외측에서 연장되어 코어부(1a)의 축단부를 감싸는 연장부(2a)가 일체형으로 성형되어 있다.The synchronizer ring 2 is fitted to the outer circumferential portion of the core portion 1a so that its inner circumferential surface is rubbed in surface contact with the outer circumference of the core portion 1a. In this embodiment, the synchronizer ring 2 extends from the outside to the shaft end of the core portion 1a. The extension part 2a which surrounds a part is molded in one piece.

이 싱크로나이저 링(2)의 연장부(2a)에는 원주방향으로 함몰되어 형성된 삽입홈에 형성되어 있으며, 이 홈에는 엽전모양의 마찰링(3)이 끼워진다.The extension portion 2a of the synchronizer ring 2 is formed in an insertion groove formed recessed in the circumferential direction, and the friction ring 3 in the shape of a lobe is fitted in the groove.

이 마찰링(3)은 코어부(1a)와 싱크로나이저 링(2)의 연장부(2a) 사이에 개재된 채로, 압축스프링(4)에 의하여 연장부(2a)에 대향하는 방향으로 탄성지지되어, 코어부(1a)의 축단부에 압착된다. 따라서, 마찰링(3)은 코어부(1a)와 연장부(2a) 사이의 마찰면적을 확대시켜 이들 두 부재 사이의 마찰력을 증대시키게 된다.The friction ring 3 is elastically supported in the direction opposite to the extension portion 2a by the compression spring 4 while being interposed between the core portion 1a and the extension portion 2a of the synchronizer ring 2. Then, it is crimped | bonded to the shaft end part of the core part 1a. Thus, the friction ring 3 enlarges the friction area between the core portion 1a and the extension portion 2a to increase the friction force between these two members.

이상과 같이, 본 실시예의 동기화장치의 코어부(1a)는 기존의 원추형의 외주면과 더불어, 축단부에서도 마찰링(3)을 사이에 두고 싱크로나이저 링(2)과 마찰되기 때문에, 마찰면적이 종래에 비하여 확대되어 변속기의 변속성능이 향상시킬 수 있을 뿐만 아니라, 마찰력의 집중을 분산시키므로써 양 부재의 마찰부 내구성도 향상시킬 수 있다.As described above, since the core portion 1a of the synchronization device of the present embodiment is rubbed with the synchronizer ring 2 with the friction ring 3 interposed therebetween, in addition to the existing conical outer peripheral surface, the friction area is reduced. Compared with the related art, the transmission performance of the transmission can be improved, and the friction part durability of both members can be improved by dispersing the concentration of frictional force.

이상에서 상세히 설명한 바와 같은 본 고안에 의하면, 수동변속기의 기어 변속성능이 크게 향상될 뿐만 아니라 코어부와 싱크로나이저 링 사이의 마찰력을 분산시키므로써 이들의 내구수명도 대폭 연장시킬 수 있다.According to the present invention as described in detail above, not only the gear shifting performance of the manual transmission is greatly improved, but also the durability life thereof can be significantly extended by dispersing frictional force between the core part and the synchronizer ring.

본 고안은 실용신안등록청구의 범위에서 청구하는 본 고안의 요지를 벗어나지 않고 당해 고안이 속하는 분야에서 통상의 지식을 가진 자가 다양하게 변경하여 실시할 수 있으므로, 본 고안은 상술한 특정의 실시예에 한정되지 않는다.The present invention can be variously modified and implemented by those of ordinary skill in the art without departing from the gist of the invention devised within the scope of the utility model registration claim, the present invention is a specific embodiment described above It is not limited.
