본 발명은 자동차의 수동변속기구에 관한 것으로, 특히 변속조작시 변속불량율을 최소화시키고 조작감을 향상시키며 아울러 변속소음을 감소시킬 수 있도록 된 자동차의 수동변속기구에 관한 것이다.The present invention relates to a manual transmission mechanism of a vehicle, and more particularly, to a manual transmission mechanism of a vehicle that is capable of minimizing a shift failure rate, improving a feeling of operation and reducing a shift noise during a shift operation.

일반적으로, 수동변속기구의 종류는 변속시 기어자체가 축선상을 섭동하면서치합되는 섭동기어식(sliding gear type)과, 주축에 끼워져 자유롭게 회전하는 단기어와 부축에 고정되어 있는 부축기어가 항상 치합된 상태로 회전하는 상시치합식(constant-mesh type 또는 dog clutch type)과, 이 상기치합식의 단점(치합소음발생 및 기어이의 파손현상)을 개선시킨 동기치합식(synchro-mesh type)으로 분류되며, 상기 동기치합식은 키형식 동기치합식과 볼형식 동기치합식 및 로킹스트립형식의 동기치합식으로 분류된다.In general, the type of manual transmission mechanism includes a perturbation gear type in which the gear itself is perturbed on the axis during shifting, and a short-term gear that is freely rotated on the main shaft and a sub-gear gear fixed to the sub shaft is always engaged. It is classified into a constant-mesh type that rotates in a state (constant-mesh type or dog clutch type), and a synchro-mesh type that improves the disadvantages of the above-mentioned type (synchronized noise generation and gear breakage). The synchronizing expressions are classified into key type synchronizing expressions, ball type synchronizing expressions, and locking strip type synchronizing expressions.

여기서, 상기 볼형식 동기치합기구의 개략적인 구조를 살펴보면 도 1에 도시된 바와 같이, 주축(1)상에 자유로이 회전가능하도록 결합되는 단기어(2,3)와, 상기 주축(1)에 의해 관통고정되어 단기어(2,3)사이에 위치되는 싱크로나이저허브(4)와, 이 싱크로나이저허브(4)의 스플라인에 설치되면서 변속레버에 의해 축방향으로 미끄럼이동하여 기어 클러치역할을 수행하는 싱크로나이저슬리브(5)와, 싱크로나이저콘(6)과 접촉하여 마찰력을 전달하면서 외주면이 싱크로나이저슬리브(5)와 연결되도록 설치되는 싱크로나이저링(7)과, 상기 싱크로나이저슬리브(5)를 고정하여 기어물림이 빠지지 않도록 하며 변속레버의 조작시 싱크로나이저슬리브(5)와 함께 이동되어 싱크로나이저링(7)을 싱크로나이저콘(6)부에 압착시키도록 하는 스트럿키(8)와, 일단이 상기 싱크로나이저허브(4)상에 지지되도록 설치되고 타단이 상기 스트럿키(8)의 관통부에 위치되도록 설치되는 싱크로나이저스프링(9)과, 상기 스트럿키(8)를 관통하는 싱크로나이저스프링(9)의 선단에 안착되면서 싱크로나이저슬리브(5)의 밑면에 형성된 안착홈(5a)내에 걸려지도록 설치되어 변속레버의 조작감을 부여하는 베어링(bearing)형상의 슬리브결합부재(11)로 구성되어 있다.Here, referring to the schematic structure of the ball type synchronization gear mechanism, as shown in FIG. 1, the short term words 2 and 3 coupled to the main shaft 1 so as to be freely rotatable, and the main shaft 1 It is installed on the synchronizer hub 4 which is penetrated and positioned between the short term words 2 and 3 and the spline of the synchronizer hub 4, and is slid in the axial direction by the shift lever to perform the gear clutch role. The synchronizer sleeve (5), the synchronizer ring (7) having an outer circumferential surface connected to the synchronizer sleeve (5) while transmitting frictional force in contact with the synchronizer cone (6), and the synchronizer sleeve (5) A strut key 8 which is fixed so that the gear bites do not fall out, and is moved together with the synchronizer sleeve 5 when the shift lever is operated to compress the synchronizer ring 7 to the synchronizer cone 6, and The above sink A synchronizer spring 9 installed so as to be supported on the furnace hub 4 and having the other end positioned at a penetrating portion of the strut key 8, and a synchronizer spring 9 passing through the strut key 8; It is composed of a bearing-shaped sleeve coupling member 11 is installed to be caught in the seating groove (5a) formed on the bottom surface of the synchronizer sleeve (5) while seated at the tip of the).

여기서, 상기 슬리브결합부재(11)는 스틸(steel)재질로 제작된다.Here, the sleeve coupling member 11 is made of steel (steel) material.

그러나, 상기와 같은 종래의 수동변속기구를 이용하여 급변속을 실시하거나 또는 진동이 심한 상태에서 변속을 하였을 때 변속이 제대로 이루어지지 않음으로써 차량을 주행시킬 수 없게 되는 문제점이 종종 발생하게 되었다.However, there is often a problem that the vehicle cannot be driven because the shift is not performed properly when a rapid shift or a shift is performed in a severe vibration state using the conventional manual shift mechanism as described above.

즉, 도 2에 도시된 바와 같이 중립상태에 있다가 변속조작이 이루어지게 되면 먼저 싱크로나이저슬리브(5)가 변속되는 방향으로 이동하게 되고, 상기 싱크로나이저슬리브(5)의 안착홈(5a)에 걸려져 있던 슬리브결합부재(11)도 일정량만큼 이동하게 된다.That is, when the shift operation is performed while being in a neutral state as shown in FIG. 2, the synchronizer sleeve 5 is first moved in a shifting direction, and is placed in the seating groove 5a of the synchronizer sleeve 5. Hanging sleeve coupling member 11 is also moved by a certain amount.

한편, 상기 싱크로나이저슬리브(5)가 변속되는 방향으로 이동되면서 슬리브결합부재(11)가 일정량만큼 이동하게 되면 스트럿키(8)도 변속되는 방향으로 밀리게 되고 이와 동시에 상기 슬리브결합부재(11)를 지지하고 있던 싱크로나이저스프링(9)도 변속되는 방향으로 기울어지는 탄성변형을 일으키게 된다.On the other hand, when the sleeve coupling member 11 is moved by a certain amount while the synchronizer sleeve 5 is shifted in the shifting direction, the strut key 8 is also pushed in the shifting direction and at the same time the sleeve coupling member 11 The synchronizer springs 9, which were supporting the same, also cause elastic deformation inclined in the direction of shifting.

이때, 변속조작이 급하게 이루어지거나 또는 차량의 진동이 심한 상태에서 이루어지게 되면 상기 싱크로나이저스프링(9)이 변속되는 방향으로 심하게 좌굴되게 되고, 이와 동시에 상기 슬리브결합부재(11)가 싱크로나이저스프링(9)으로부터 이탈되면서 그 기능을 제대로 수행할 수 없게 되고, 이로 인해 변속조작이 제대로 이루어지지 못하게 되는 문제점이 있었다.At this time, when the shift operation is made in a hurry or when the vibration of the vehicle is made in a severe state, the synchronizer spring 9 is severely buckled in the shifting direction, and at the same time, the sleeve coupling member 11 is synchronized with the synchronizer spring ( 9) as a deviation from the function can not be performed properly, due to this there was a problem that the shift operation is not performed properly.

또한, 상기 슬리브결합부재(11)가 싱크로나이저스프링(9)으로부터 이탈되면서 단기어(2,3)사이에 끼이거나 또는 상기 스트럿키(8)의 일부분이 싱크로나이저슬리브(5)와 싱크로나이저링(7)사이에 끼여져 물려지게 되면, 운전자가 원하는 변속단으로의 변속이 제대로 이루어지지 않게 되고 이로 인해 차량을 주행시킬 수 없게 되는 문제점이 있었다.In addition, the sleeve coupling member 11 is separated from the synchronizer spring 9, and is caught between the short term words 2 and 3, or a part of the strut key 8 is synchronized with the synchronizer sleeve 5 and the synchronizer ring. If it is sandwiched between the (7), there is a problem that the shift to the gear shifting desired by the driver is not made properly, which makes it impossible to drive the vehicle.

한편, 상기와 같은 문제점을 예방하기 위해 싱크로나이저스프링(9)과 슬리브결합부재(11)를 일체화시킨 수동변속기구를 사용하였으나, 상기 싱크로나이저스프링(9)과 슬리브결합부재(11)를 일체화시키게 되면 형상이 복잡하여 그 기능에 비해 단가가 대폭적으로 상승된다는 문제점이 여전히 남아있게 되었다.Meanwhile, in order to prevent the above problems, a manual transmission mechanism in which the synchronizer spring 9 and the sleeve coupling member 11 are integrated is used, but the synchronizer spring 9 and the sleeve coupling member 11 are integrated. The problem is that the shape is complicated and the unit cost is significantly increased compared to the function.

이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 싱크로나이저스프링과 슬리브결합부재의 결합성을 향상시켜 변속조작이 급하게 이루어지거나 또는 차량의 진동이 심한 상태에서 변속이 이루어질 때 상기 싱크로나이저스프링이 변속되는 방향으로 심하게 좌굴되더라도, 상기 슬리브결합부재가 싱크로나이저스프링으로부터 이탈되면서 단기어사이에 물리거나 또는 상기 스트럿키의 일부분이 싱크로나이저슬리브와 싱크로나이저링사이에 끼여져 물려지게 되는 것을 방지하여, 운전자가 원하는 변속단으로 변속조작이 원활하게 이루어지도록 하고 아울러 조작감을 향상시키면서 변속소음을 감소시킬 수 있도록 된 자동차의 수동변속기구를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, by improving the coupling of the synchronizer spring and the sleeve coupling member to the shift operation is made urgently or when the shift is made in a severe vibration of the vehicle the synchronizer Even if the spring is severely buckled in the shifting direction, the sleeve coupling member is prevented from being caught by the short-term fish while being separated from the synchronizer spring, or part of the strut key is caught between the synchronizer sleeve and the synchronizer ring. Accordingly, an object of the present invention is to provide a manual transmission mechanism of a vehicle that enables a shift operation to be performed smoothly to a shift stage desired by a driver and also reduces shift noise while improving a feeling of operation.

상기와 같은 목적을 달성하기 위한 본 발명의 수동변속기구는, 일단이 싱크로나이저허브상에 지지되도록 설치되면서 타단이 스트럿키의 관통부내에 위치되도록 설치되는 싱크로나이저스프링과, 일단이 상기 싱크로나이저스프링의 안쪽으로 삽입되고 타단이 싱크로나이저스프링의 선단에 지지되면서 스트럿키를 관통하도록설치됨과 더불어 그 선단이 싱크로나이저슬리브의 밑면에 형성된 안착홈내에 걸려지도록 설치되어 변속레버의 조작감을 부여하도록 된 슬리브결합부재를 포함하여 구성되는 것을 특징으로 한다.The manual transmission mechanism of the present invention for achieving the above object is a synchronizer spring, one end of which is installed to be supported on the synchronizer hub and the other end of which is located in the through portion of the strut key, and one end of the synchronizer spring.

도 3은 본 발명에 따른 수동변속기구를 설명하기 위한 종단면도로서, 종래구조와 동일한 부위에는 동일한 참조부호를 붙이면서 설명하기로 한다.3 is a longitudinal sectional view for explaining the manual transmission mechanism according to the present invention, and the same parts as in the conventional structure will be described with the same reference numerals.

본 발명에 따른 수동변속기구는 도 1을 참조로 전술한 바와 같이, 주축(1)상에 자유로이 회전가능하도록 결합되는 단기어(2,3)와, 상기 주축(1)에 의해 관통고정되어 단기어(2,3)사이에 위치되는 싱크로나이저허브(4)와, 이 싱크로나이저허브(4)의 스플라인에 설치되면서 변속레버에 의해 축방향으로 미끄럼이동하여 기어 클러치역할을 수행하는 싱크로나이저슬리브(5)와, 싱크로나이저콘(6)과 접촉하여 마찰력을 전달하면서 외주면이 싱크로나이저슬리브(5)와 연결되도록 설치되는 싱크로나이저링(7)과, 상기 싱크로나이저슬리브(5)를 고정하여 기어물림이 빠지지 않도록 하며 변속레버의 조작시 싱크로나이저슬리브(5)와 함께 이동되어 싱크로나이저링(7)을 싱크로나이저콘(6)부에 압착시키도록 하는 스트럿키(8)와, 일단이 상기 싱크로나이저허브(4)상에 지지되도록 설치되고 타단이 상기 스트럿키(8)의 관통부에 위치되도록 설치되는 싱크로나이저스프링(9)으로 구성된다.Manual transmission mechanism according to the present invention, as described above with reference to Figure 1, the short-term words (2, 3) are coupled to be rotatable freely on the main shaft (1), and the short-term word is fixed through the main shaft (1) Synchronizer hub (4) positioned between (2, 3) and a synchronizer sleeve (5), which is installed on the spline of the synchronizer hub (4) and slides in the axial direction by the shift lever to perform a gear clutch role (5). ), The synchronizer ring 7 and the synchronizer sleeve 5 which are installed such that the outer peripheral surface is connected to the synchronizer sleeve 5 while transmitting frictional force in contact with the synchronizer cone 6 and the synchronizer sleeve 5 are fixed. Strut key (8) which is moved together with the synchronizer sleeve (5) so as to press the synchronizer ring (7) to the synchronizer cone (6) during operation of the shift lever, and one end of the synchronizer hub (4) support That is provided and the other end is composed of a synchronizer spring 9 is installed so as to be located at the perforations of the said strut keys (8).

또한, 본 발명에 따른 수동변속기구는 도 3에 도시된 바와 같이, 일단이 상기 싱크로나이저스프링(9)의 안쪽으로 삽입되고 타단이 싱크로나이저스프링(9)의 선단에 지지되면서 스트럿키(8)를 관통하도록 설치됨과 더불어 그 선단이 싱크로나이저슬리브(5)의 밑면에 형성된 안착홈(5a)내에 걸려지도록 설치되어 변속레버의 조작감을 부여하도록 된 슬리브결합부재(21)를 포함하여 구성된다.In addition, the manual transmission mechanism according to the present invention, as shown in Figure 3, one end is inserted into the synchronizer spring (9) and the other end is supported by the front end of the synchronizer spring (9) while holding the strut key (8) In addition to being installed so as to penetrate, the front end is configured to include a sleeve engaging member 21 which is installed to be caught in the seating groove 5a formed at the bottom of the synchronizer sleeve 5 to impart a feeling of operation of the shift lever.

여기서, 상기 슬리브결합부재(21)는 싱크로나이저스프링(9)의 안쪽으로 삽입되어 변속조작시 상기 싱크로나이저스프링(9)으로부터 이탈되는 것을 방지하도록 원형봉으로 형성되는 이탈방지돌기부(21a)와, 일단이 상기 이탈방지돌기부(21a)와 일체로 형성되면서 싱크로나이저스프링(9)에 안착되도록 설치되고 타단이 스트럿키(8)를 관통하여 싱크로나이저슬리브(5)의 안착홈(5a)내에 걸려지도록 설치되는 원형돌기부(21b)로 구성된다.Here, the sleeve coupling member 21 is inserted into the synchronizer spring (9) and the separation prevention projection portion (21a) formed of a circular rod to prevent the deviation from the synchronizer spring (9) during shifting operation; One end is integrally formed with the release preventing protrusion 21a and is installed to be seated in the synchronizer spring 9, and the other end penetrates the strut key 8 so as to be caught in the seating groove 5a of the synchronizer sleeve 5. It is composed of a circular projection (21b) is installed.

한편, 상기 슬리브결합부재(21)는 변속조작시 걸리는 하중만 충분히 지탱할 수 있을 정도의 강도만 가지고 있으면 되고 아울러 변속조작시 그 이동거리도 짧기 때문에 플라스틱을 이용하여 높은 강도를 가지도록 사출성형되게 된다.On the other hand, the sleeve coupling member 21 is required to have only enough strength to support only the load applied during the shift operation, and also because the movement distance is short during the shift operation, it is injection molded to have a high strength using plastic. .

또한, 상기 싱크로나이저슬리브(5)에는 변속조작시 싱크로나이저슬리브(5)와 상기 슬리브결합부재(21)의 원형돌기부(21b)와의 마찰을 최소화시키기 위해 변속기 오일을 유입시키는 복수개의 오일홀(5b)이 형성되는 구조로 되어 있다.In addition, the synchronizer sleeve 5 includes a plurality of oil holes 5b for introducing transmission oil to minimize friction between the synchronizer sleeve 5 and the circular protrusion 21b of the sleeve coupling member 21 during the shift operation. ) Is formed.

따라서, 중립상태에 있던 본 발명에 따른 수동변속기구를 변속조작이 이루어지게 변속조작하게 되면 먼저 싱크로나이저슬리브(5)가 변속되는 방향으로 이동하게 되고, 상기 싱크로나이저슬리브(5)의 안착홈(5a)에 걸려져 있던 슬리브결합부재(21)도 일정량만큼 이동하게 된다.Therefore, when the manual transmission mechanism according to the present invention in the neutral state is shifted to make the shifting operation, the first shifting direction of the synchronizer sleeve 5 is shifted, and the seating groove of the synchronizer sleeve 5 ( The sleeve engaging member 21, which was hooked to 5a), is also moved by a certain amount.

그리고, 상기 싱크로나이저슬리브(5)가 변속되는 방향으로 이동되면서 슬리브결합부재(11)가 일정량만큼 이동하게 되면 스트럿키(8)도 변속되는 방향으로 밀리게 되고 이와 동시에 상기 슬리브결합부재(21)를 지지하고 있던 싱크로나이저스프링(9)도 변속되는 방향으로 기울어지는 탄성변형을 일으키게 된다.In addition, when the sleeve coupling member 11 is moved by a predetermined amount while the synchronizer sleeve 5 is shifted in the shifting direction, the strut key 8 is also pushed in the shifting direction, and at the same time, the sleeve coupling member 21 is moved. The synchronizer springs 9, which were supporting the same, also cause elastic deformation inclined in the direction of shifting.

한편, 변속조작이 급하게 이루어지거나 또는 차량의 진동이 심한 상태에서 변속조작이 이루어지게 되면 상기 싱크로나이저스프링(9)이 변속되는 방향으로 심하게 좌굴되는데, 이와 같이 싱크로나이저스프링(9)이 변속되는 방향으로 심하게 좌굴되더라도 싱크로나이저스프링(9)의 안쪽으로 삽입된 슬리브결합부재(21)의 이탈방지돌기부(21a)가 싱크로나이저스프링(9)으로부터 이탈되는 것이 방지되게 되며, 이로 인해 전체적인 슬리브결합부재(21)가 싱크로나이저스프링(9)으로부터 이탈되는 것이 방지되게 된다.On the other hand, if the shift operation is made in a hurry or when the shift operation is performed in a state in which the vibration of the vehicle is severe, the synchronizer spring 9 is severely buckled in the shifting direction, and thus the direction in which the synchronizer spring 9 is shifted. Even if it is severely buckled, the separation preventing protrusion 21a of the sleeve coupling member 21 inserted into the synchronizer spring 9 is prevented from being separated from the synchronizer spring 9, and thus the overall sleeve coupling member ( 21 is prevented from leaving the synchronizer spring 9.

그리고, 상기 슬리브결합부재(21)가 싱크로나이저스프링(9)으로부터 이탈되는 것이 방지되면, 상기 슬리브결합부재(21)가 단기어(2,3)사이에 끼이거나 또는 상기 스트럿키(8)의 일부분이 싱크로나이저슬리브(5)와 싱크로나이저링(7)사이에 끼여져 물려지게 되는 것이 방지되게 되며, 이로 인해 본 발명에 따른 수동변속기구는 운전자가 원하는 변속단으로 원활하게 변속이 이루어지게 되며, 아울러 주행중인 차량도 운전자가 원하는 변속단에서 주행을 시킬 수 있게 된다.When the sleeve coupling member 21 is prevented from being separated from the synchronizer spring 9, the sleeve coupling member 21 is sandwiched between the short term words 2 and 3 or the strut key 8 is closed. A part is prevented from being caught between the synchronizer sleeve 5 and the synchronizer ring 7, and thus the manual transmission mechanism according to the present invention is smoothly shifted to a shift stage desired by the driver. In addition, the vehicle being driven can also be driven at the gear shift desired by the driver.

또한, 수동변속기구를 구성하는 본 발명에 따른 슬리브결합부재(21)가 플라스특 사출성형으로 이루어지게 되면, 스틸로 이루어진 종래의 슬리브결합부재(11)보다 경량화를 이룩할 수 있게 된다.In addition, when the sleeve coupling member 21 according to the present invention constituting the manual transmission mechanism is made of plastic injection molding, it is possible to achieve a lighter weight than the conventional sleeve coupling member 11 made of steel.

또한, 변속조작시 싱크로나이저슬리브(5)에 형성된 오일홀(5b)을 통해 변속기 오일이 유입되면, 싱크로나이저슬리브(5)와 슬리브결합부재(21)의 원형돌기부(21b)와의 마찰이 최소화되게 되며, 이로 인해 변속조작감이 향상되면서 변속조작소음도 최소화시킬 수 있게 된다.In addition, when the transmission oil flows through the oil hole 5b formed in the synchronizer sleeve 5 during the shifting operation, friction between the synchronizer sleeve 5 and the circular protrusion 21b of the sleeve coupling member 21 is minimized. As a result, the shift operation feeling is improved and the shift operation noise can be minimized.

이상 설명한 바와 같이 본 발명에 의하면, 변속조작이 급하게 이루어지거나 또는 차량의 진동이 심한 상태에서 변속조작이 이루어져 싱크로나이저스프링이 변속되는 방향으로 심하게 좌굴되더라도 슬리브결합부재가 싱크로나이저스프링으로부터 이탈되는 것이 방지되게 되고, 이로 인해 운전자가 원하는 변속단으로 원활하게 변속이 이루어지게 되며, 아울러 싱크로나이저슬리브와 슬리브결합부재의 원형돌기부와의 마찰이 최소화되면서 변속조작감이 향상될 뿐만 아니라 변속조작소음도 최소화되는 효과가 있게 된다.As described above, according to the present invention, even if the shift operation is made in a hurry or the shift operation is performed in a state in which the vibration of the vehicle is severe, the sleeve coupling member is prevented from being separated from the synchronizer spring even if the synchronizer spring is severely buckled in the shifting direction. As a result, the shift is smoothly made to the shift stage desired by the driver, and the friction between the synchronizer sleeve and the circular protrusion of the sleeve coupling member is minimized, thereby improving the shift operation feeling and also minimizing the shift operation noise. Will be.
