본 고안은 역진방지장치를 갖춘 자동차의 수동변속기에 관한 것으로, 특히 수동변속기의 구동축상의 1단기어 측부에 역회전을 방지하는 일방향클러치를 장착시켜 1단 변속시 구동축의 역회전을 억제시켜 등판로의 정지후 재출발시 차체가 후방으로 밀려나지 않을 수 있도록 된 역진방지장치를 갖춘 자동차의 수동변속기에 관한 것이다. 주지된 바와 같이 자동차의 엔진룸에 장착된 변속기는 엔진과 추진축사이에 설치되어 엔진에서 발생되는 동력을 자동차의 주행상태에 알맞도록 그 회전력과 회전속도를 변환시켜 구동바퀴에 전달하는 기능을 하는 바, 이러한 변속기중에서 주행중변속을 운전자가 변속레버를 매번 조작하여 이루어지도록 된 수동변속기에서는 엔진으로부터 발생된 동력을 클러치를 거쳐 구동축이 받아 이를 변속기구의 조작에 따라 종동축의 해당기어로 전달시켜 차체를 구동시켜 왔다. 그런데 상기와 같은 수동변속기를 탑재하고 있는 자동차에서는 경사진 등판로의 주행시 기어의 1단변속을 위해 잠시 정지한 다음 1단변속후 재출발할 경우에 있어서, 엔진으로부터 발생되는 최초회전력이 차체가 뒤로 밀리거나 극단적인 경우 시동이 꺼지게 되는 단점이 있는데 이러한 것은 각 페달의 조작이 서투른 초보운전자나 여성운전자의 경우에는 빈번하게 발생되는 불편함이기도 하였다. 또한, 차체가 뒤로 밀릴 경우 뒤따르던 차량과의 접촉사고유발의 위험성도 가지고 있었다. 이에 본 고안은 상기와 같은 제반 단점들을 해소하기 위해 안출된 것으로, 수동변속기의 구동축상에 역회전방지용 일방향클러치를 1단기어의 측부에 설치하여 1단기어의 변속기 이 일방향클러치도 동시에 구동축상에 체결되어 등판로에서 정지후 재출발시 차체가 후방으로 밀리는 것을 방지할 수 있도록 된 역진방지장치를 갖춘 자동차의 수동변속기를 제공함에 그 목적이 있다. 상기와 같은 목적을 달성하기 위한 본 고안은, 구동축상에 1단기어와 후진기어 사이에 이 구동축과 일체를 이루는 스플라인이 형성되고, 이 스플라인측부에 삽입부를 일측에 갖추고서 내주면에 구동축상의 스플라인으로 결합되도록 스플라인이 형성되면서 외부에는 한방향으로만 회전을 가능케 해주는 일방향 클러치가 장착되어, 상기 일방향클러치의 측부에 일체로 형성된 삽입부와, 종동축상의 1/2단용 동기치합장치의 슬리브에 형성된 삽입부에는 변속레버의 스프트포크가 삽입되어 1단변속시 이들을 동시에 동작시키도록 구성되어 있다. 이하, 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.The present invention relates to a manual transmission of a vehicle equipped with a reverse prevention device, and in particular, by installing a one-way clutch to prevent the reverse rotation on the side of the first gear on the drive shaft of the manual transmission to prevent the reverse rotation of the drive shaft during the first gear shift It relates to a manual transmission of a vehicle equipped with a reverse prevention device to prevent the body from being pushed rearward after restarting. As is well known, a transmission mounted in an engine room of a vehicle is installed between the engine and the propulsion shaft to convert the power generated from the engine to the driving wheel by converting the rotational force and the rotational speed to suit the driving state of the vehicle. In the manual transmission, in which the driver operates the shift lever every time in the transmission, the drive shaft receives the power generated from the engine via the clutch and transfers it to the corresponding gear of the driven shaft according to the operation of the transmission mechanism to drive the vehicle body. Has been made. However, in a vehicle equipped with the manual transmission as described above, when the vehicle stops for a first gear shift and then restarts after the first gear shift when driving on a sloped slope, the initial rotational power generated from the engine is pushed backward. In the extreme case, there is a disadvantage in that the starting is turned off. This is also a inconvenience that frequently occurs in the case of a beginner driver or a female driver who each pedal operation is poor. There was also a risk of accidental contact with the vehicle when it was pushed back. The present invention has been devised to solve the above-mentioned disadvantages, and by installing a one-way clutch for preventing reverse rotation on the side of the first gear on the drive shaft of the manual transmission, the one-way clutch of the first gear is also on the drive shaft at the same time. It is an object of the present invention to provide a manual transmission of a vehicle having a reverse prevention device which is fastened to prevent the vehicle body from being pushed rearward when restarting after stopping at a climbing road. The present invention for achieving the above object, a spline which is integral with the drive shaft is formed between the first gear and the reverse gear on the drive shaft, the spline side is provided with an insertion portion on one side and coupled to the spline on the drive shaft on the inner peripheral surface The spline is formed so that the one-way clutch is mounted on the outside to allow rotation in only one direction, the insertion portion formed integrally with the side of the one-way clutch, and the insertion portion formed in the sleeve of the 1/2 stage synchronous gear on the driven shaft. A shift fork of the shift lever is inserted and configured to operate them simultaneously in one shift. Hereinafter, the present invention will be described in detail based on the accompanying drawings.
제1도는 본 고안에 따라 역진방지장치를 갖춘 수동변속기의 내부상태도이고, 제2도는 본 고안의 요부인 역진방지장치의 확대단면도이다. 본 고안의 수동변속기는 도면에 도시된 바와 같이, 구동축(1)상에 1단기어(2)와 후진기어(3)사이에 이 구동축(1)과 일체를 이루는 스플라인(4)이 형성되고, 이 스플라인(4)측부에 삽입부(5a)를 일측에 갖추고서 내주면에 구동축(1)상의 스플라인(4)으로 결합되도록 스플라인(도시안됨)이 형성되면서 외부에는 한방향으로만 회전을 가능케 해주는 스프래그(Sprag)을 외측레이스와 내측레이스사이에 다수개로 내장하고 있는 일방향클러치(One Way Clutch:5)가 장착되어 있는 구조로 되어 있다. 여기서 상기 일방향클러치(5)측부에 일체로 형성된 삽입부(5a)와, 종동축(6)상의 1/2단용 동기치합장치(7)의 슬리브(8)에 형성된 삽입부(8a)에는 변속레버(도시안됨)로 부터 연장되어 동기치합장치의 슬리브(8)를 좌/우로 이동시키도록 하는 시프트포크(도시안됨)가 삽입되어 이들을 동시에 작동시키도록 되어 있다. 따라서 상기 변속레버에 의한 1단변속시에는 일방향클러치(5)측부의 삽입부(5a)와 1/2단용 동기치합장치(7)의 삽입부(8a)에 동시삽입된 시프트포크(도시안됨)가 이들을 우측으로 이동시켜, 상기 구동축(1)상의 스플라인(4)에 일방향클러치(5)가 맞물림식으로 결합되면서 종동축(6)상의 1/2단용 동기치합장치(7)도 1단기어(2')쪽으로 이동되어 1단변속이 완료되어지는데, 이때 상기 구동축(1)상의 일방향클러치(5)는 엔진의 회전방향과 동일하게 구동축(1)이 회전될 경우에만 회전을 허용하고 그 반대방향으로의 회전은 방지하게 된다. 즉, 자동차가 경사진 등판로 주행할 경우, 일단 정지하고서 1단변속 완료후 재출발할 때 기어가 끼워지지 않은 상태로 인해 발생되는 차제의 역진에 따른 구동축(1)의 역회전을 방지할 수 있게 되어 차체가 후방으로 밀려나지 않게 된다. 이상 설명한 바와 같이 본 고안에 의하면, 상기 수동변속기의 구동축(1)상에 1단변속시 구동축(1)과 일체성형된 스플라인(4)과 치합되는 일방향클러치(5)를 장착함으로써, 경사진 등판로의 주행시 차체가 후방으로 밀려나지 않게 해주어 운전이 미숙한 초보운전자나 여성운전자에게 유용함을 줄 수 있는 효과가 있게 된다.1 is an internal state diagram of a manual transmission with a reverse prevention device according to the present invention, Figure 2 is an enlarged cross-sectional view of the reverse prevention device that is the main part of the present invention. In the manual transmission of the present invention, as shown in the drawing, a spline 4 integral with the drive shaft 1 is formed between the first gear 2 and the reverse gear 3 on the drive shaft 1, A sprag (not shown) having an insertion portion 5a on one side of the spline 4 on one side to be coupled to the spline 4 on the drive shaft 1 on the inner circumferential surface thereof, thereby allowing rotation outside in one direction only. It has a structure in which one way clutch (5) in which a plurality of slags are incorporated between the outer race and the inner race is mounted. Here, the shifting lever is provided in the inserting portion 5a formed integrally with the one-way clutch 5 side and the inserting portion 8a formed in the sleeve 8 of the 1 / 2-speed synchronizing gear 7 on the driven shaft 6. A shift fork (not shown) which extends from (not shown) to move the sleeve 8 of the synchronizing gear to the left / right is inserted to operate them simultaneously. Therefore, when shifting by the shift lever in one step, a shift fork (not shown) simultaneously inserted into the inserting portion 5a of the one-way clutch 5 side and the inserting portion 8a of the 1 / 2-speed synchronizing gear 7 is shown. The one-way clutch 5 is engaged with the spline 4 on the drive shaft 1 in such a manner as to move them to the right, and the 1/2 stage synchronous gear 7 on the driven shaft 6 also has a single gear ( 2 ') is moved to complete the first step, wherein the one-way clutch 5 on the drive shaft (1) allows rotation only when the drive shaft (1) is rotated in the same direction as the rotation direction of the engine and the opposite direction Rotation to is prevented. That is, when the vehicle is traveling on a sloped slope, it is possible to prevent the reverse rotation of the drive shaft (1) due to the reverse of the vehicle generated due to the state that the gear is not fitted when the vehicle is stopped and restarted after completion of the first gear shift. This prevents the body from being pushed backwards. As described above, according to the present invention, the inclined back plate is mounted on the drive shaft 1 of the manual transmission by mounting the one-way clutch 5 engaged with the spline 4 integrally formed with the drive shaft 1 during the single shift. The body is not pushed back when driving on the road, so that the driving can be useful for inexperienced novice or female drivers.
