Abstract

본 고안은 수동변속기 장착차량이 오르막길에서 멈추었다가 출발할 때 차량이 아래쪽으로 밀리는 것을 방지하기 위한 장치에 관한 것이다.The present invention relates to a device for preventing the vehicle from being pushed downward when the manual transmission vehicle stops on an uphill road and starts.

1속 변속 싱크로메시기구에 싱크로나이저 슬립(20)과 일정간격을 두고 부착기어(30)를 결합하여 고정하고, 이 기어(30)와 싱크로나이저 슬립(20) 사이에 역회전방지장치(40)를 위치시킨다. 역회전방지장치(40)는 일방향으로만 회전하게 되어 있기 때문에 1속기어(10)가 연결된 상태(1속 변속 상태)에서는, 운전자가 클러치 페달을 밟은 상태에서 브레이크 페달에서 발을 떼어도 차량이 뒤로 밀리지 않게 된다. 차량이 출발한 후, 1속 기어(10)와 싱크로메시기구가 떨어지면 역회전방지장치(40)의 래칫휠 내부기어(41)도 부착기어(30)와의 연결이 해제된다. 즉, 이 역회전방지장치(40)는 1속으로 변속한 상태에서만 작동한다. 후진의 경우에도 원리 및 장치는 같다.The attachment gear 30 is fixed to the 1-speed synchro mesh mechanism with the synchronizer slip 20 at a predetermined interval, and the reverse rotation prevention device 40 is connected between the gear 30 and the synchronizer slip 20. Locate it. Since the reverse rotation prevention device 40 rotates only in one direction, in the state where the first speed gear 10 is connected (1 speed shift state), even when the driver steps on the clutch pedal, the vehicle is stopped. You will not be pushed back. After the vehicle starts, when the first gear 10 and the synchronization mesh mechanism fall, the ratchet wheel internal gear 41 of the reverse rotation preventing device 40 is also disconnected from the attachment gear 30. In other words, the reverse rotation prevention device 40 operates only in the state of shifting at one speed. The principle and device are the same in the case of reverse.

따라서 오르막길에서 출발할 때, 미숙한 운전자라도 1속으로 변속한 후에는 브레이크에서 발을 떼어도 차량이 뒤로 밀리지 않기 때문에 가속페달을 서서히 밟아 가속하면서 클러치를 떼어 차를 부드럽게 출발시킬 수 있어 차량의 운행을 안전하고 원활하게 하여 준다.Therefore, when starting from an uphill road, even if an inexperienced driver shifts to 1 speed, the vehicle will not be pushed back even if the foot is released from the brake, so the vehicle can be started smoothly by releasing the clutch while gradually accelerating by pressing the accelerator pedal. Makes it safe and smooth.

Description

수동변속기 차량의 밀림방지장치{Slip-resistant device of transmission}Slip-resistant device of transmission

본 고안은 수동변속기 장착차량이 운행도중 경사로상에서 일시 정지하였다가 출발할 때 또는 경사로 위쪽으로 후진하고자 할 때 자동차의 자체 중량 등으로 인하여 경사로 아래쪽으로 밀리는 현상을 방지하여 안전출발을 가능하게 하여 주는 장치에 관한 것이다.The present device prevents the vehicle from being pushed down the ramp due to the weight of the vehicle when the vehicle equipped with the manual transmission is temporarily stopped on the ramp while driving or reversing upward. It is about.

수동변속기 장착차량이 경사로상에서 운전자가 브레이크 페달을 밟아 정지상태를 유지하고 있다가 출발하기 위하여 가속페달을 밟으려고 발을 떼는 순간부터 반클러치 상태로 구동축에 적절한 회전력이 전달되기까지의 시간동안 자동차의 중량 등에 의하여 차량이 경사로 아래로 밀리는 현상이 발생한다. 이렇게 자동차가 뒤로 밀렸다가 전진하게 될 경우 동력전달 계통에 무리를 주게 되어 고장의 원인이 되기도 하며, 또 자동차가 뒤로 밀리면 후방차량과 충돌사고를 유발하기까지 한다.A vehicle with a manual transmission keeps a stop on the incline while the driver presses the brake pedal and stops.Then, when the driver releases his or her foot to step on the accelerator pedal to start, the vehicle stops for half a clutch until the proper torque is transmitted to the drive shaft. The phenomenon in which the vehicle is pushed down the slope due to the weight or the like occurs. If the car is pushed backwards and moves forward, it causes the power transmission system to be overwhelmed, which may cause a breakdown, and if the car is pushed backwards, it may cause a collision with the rear vehicle.

따라서, 운전자는 출발시 오른발을 브레이크 페달에서 뗌과 동시에 가속페달을 밟고 동시에 왼발은 클러치 페달에서 부드럽게 떼는 일련의 동작을 신속하고도 부드럽게 수행하여야만 된다. 그러나, 수동변속기 장착차량으로 경사로에서 일시정지 하였다가 출발할 때의 변속조작은 초보운전자뿐만 아니라, 어느 정도 숙련된 운전자에게도 어려운 기술이며, 운전자를 부담스럽게 하고 피로감을 쌓이게 할 뿐 아니라 사고의 위험 또한 크다.Therefore, the driver must perform a series of movements in which the right foot is released from the brake pedal at the same time and the accelerator pedal is simultaneously released while the left foot is gently released from the clutch pedal. However, the shift operation when starting and stopping on a ramp with a manual transmission vehicle is a difficult technique not only for a novice driver but also to some skilled drivers, which not only makes the driver burdened and fatigues, but also the risk of an accident. Big.

이러한 수동변속기 장착차량의 문제점은 현재에도 현실적인 대안이 없는 듯하며 따라서 자동변속기 장착 자동차를 선호하는 경향이 뚜렷하다. 그러나 자동변속기 장착 비용, 연비, 출력 등의 문제로 승용차 특히, 화물차 등에는 여전히 수동변속기를 장착하는 자동차가 많이 있으므로, 간단하고도 비용이 저렴하며 다른 부품 등의 수명에도 영향을 주지 아니하는 상기 장치로써 이와 같은 문제점을 해결하는 것이 필요하다.The problem with such a manual transmission vehicle does not seem to be a realistic alternative at present, and therefore, there is a clear tendency to prefer a vehicle with an automatic transmission. However, due to problems such as automatic transmission installation cost, fuel economy, and output, many passenger cars, especially trucks, are still equipped with manual transmissions, so the above devices are simple and inexpensive and do not affect the life of other parts. It is necessary to solve this problem.

본 고안은 이러한 문제점을 해결하기 위하여 고안된 것으로서, 자동차의 수동변속기 내에 역회전방지장치를 추가함으로서 경사로에서 일시정지 하였다가 출발하거나, 경사로 위쪽으로 후진할 때, 운전자의 페달조작 숙련도와는 무관하게 자동차가 아래쪽으로 밀리는 것을 근본적으로 방지하여 안전하게 출발할 수 있게 한 장치이다.The present invention is designed to solve the above problems, and by adding a reverse rotation prevention device in the manual transmission of the vehicle, the vehicle is temporarily stopped on the ramp and starts or reverses upward, regardless of the driver's pedaling skill. Is a device that prevents the car from being pushed downwards so that it can start safely.

자동차 출발을 위하여 수동변속기의 1속기어(10)에 싱크로메시기구를 밀착시킬 때(1속 변속시), 싱크로메시기구에 슬립(20)과 일정간격을 두고 결합하여 고정한 부착기어(30)도 역회전방지장치의 래칫휠 내부기어(41)에 동시에 연결되도록 역회전방지장치(40)를 배치한다. 이때 역회전방지장치(40)는 일방향으로만 회전하도록 구성되어 있어, 1속 변속 상태에서 클러치 페달을 밟은 상태에서는 브레이크 페달에서 발을 떼더라도 자동차가 뒤로 밀리지 않게 되어(후진 변속의 경우에도 원리는 같음) 운전이 미숙한 사람들에게도 평지에서와 마찬가지로 안심하고 안전하게 출발하도록 도와주는 역회전방지장치(40, 70)를 제공하는 것을 목적으로 한다.When the synchro mesh mechanism is in close contact with the first gear 10 of the manual transmission for the start of the vehicle (when the first speed is shifted), the attachment gear 30 is also fixed to the synchro mesh mechanism by combining the slip 20 with a fixed interval. The reverse rotation prevention device 40 is disposed to be simultaneously connected to the ratchet wheel internal gear 41 of the reverse rotation prevention device. At this time, the reverse rotation prevention device 40 is configured to rotate only in one direction, so that the vehicle is not pushed back even when the foot is released from the brake pedal in the state where the clutch pedal is pressed in the 1 speed shift state (although in the case of the reverse shift Equal) It is an object to provide a reverse rotation prevention device (40, 70) to help those who are inexperienced to drive safely and safely, as in the plain.

본 고안은 도2, 도3 및 도5에 도시된 바와 같이 자동차의 수동변속기의 1속 싱크로메시기구에 싱크로나이저 슬립(20)과 일정간격을 두고 부착기어(30)를 결합하여 고정하고, 이 기어(30)와 싱크로나이저 슬립(20) 사이에는 래칫휠을 갖는 역회전방지장치(40)를 위치시켜, 이 장치(40)를 변속기 케이스에 고정하되, 상기 역회전방지장치(40)는 변속기가 1속으로 변속되었을 때에는 상기 부착기어(30)와 역회전방지장치의 래칫휠 내부기어(41)가 연결되고, 그밖의 경우에는 상기 부착기어(30)와 싱크로나이저 슬립(20) 사이에 위치하도록 한 것이다.The present invention, as shown in Figures 2, 3 and 5 by fixing the attachment gear 30 at a certain interval with the synchronizer slip 20 to the first speed synchronization mesh mechanism of the manual transmission of the vehicle, A reverse rotation prevention device 40 having a ratchet wheel is positioned between the gear 30 and the synchronizer slip 20 to fix the device 40 to the transmission case, but the reverse rotation prevention device 40 is connected to the transmission. When the gear is shifted at 1 speed, the attachment gear 30 and the ratchet wheel internal gear 41 of the reverse rotation prevention device are connected to each other. Otherwise, the attachment gear 30 is positioned between the attachment gear 30 and the synchronizer slip 20. I did it.

상기 역회전방지장치(40)는 도4에 도시된 바와 같이 변속기의 케이스에 고정되는 역회전방지장치 케이스(43, 44)와 이 케이스의 내부에서 회전되는 래칫휠로 구성되고, 상기 래칫휠은 그 내부에 상기 부착기어(30)와 맞물릴 수 있는 내부기어(41)가 형성되고, 외부 중앙 둘레에는 래칫기어(42)가 형성되고, 상기 케이스(43, 44)의 내부에는 복수개의 폴(45)이 스프링(46)에 의하여 탄지된 상태로 상기 래칫기어(42)에 물릴 수 있도록 결합된 것이다. 래칫기어(42)는 래칫휠의 외부 둘레의 중앙에만 형성되어 있기 때문에 래칫기어가 형성되지 않은 좌우측 부분은 래칫휠 축(49)이 된다. 래칫휠 축에는 판형 베어링을 결합하고 윤활유를 칠하여 래칫휠이 원활하게 회전할 수 있도록 한다.래칫휠의 내부기어(41)와 싱크로메시기구의 부착기어(30)가 원활하게 맞물릴 수 있도록 하기 위하여 도8에 도시된 바와 같이 두 기어가 맞물릴 때 처음 만나는 기어날에 경사면을 형성한다.역회전방지장치(40)의 케이스(43, 44)에 결합되는 폴(45)은 자동차의 종류에 따라 적절한 개수로 할 수 있다. 예를 들어 승용차의 경우에는 폴을 3개 또는 4개를 창착하는 반면 화물차 및 대형 버스 등의 경우에는 5개 또는 그 이상을 장치함으로써 안전성을 높일 수 있다. 역회전방지장치를 고정하는 고정부(48)도 필요에 따라 적절한 개수로 할 수 있다.도2 및 도3은 변속기가 중립에 있는 경우를 나타낸다. 1속으로 변속될 때는 1속 싱크로메시기구가 좌측으로 움직이면서 그것에 고정되어 있는 부착기어(30)도 좌측으로 이동되어 역회전방지장치(40)의 래칫휠 내부기어(41)와 결합하여 역회전방지장치가 작동하게 된다. 그러나, 변속기가 중립 또는 1속 이외로 변속된 경우에는 역회전방지장치가 부착기어(30)와 슬립(20)사이에 위치하기 때문에 역회전방지장치가 작동하지 않는다.역회전방지장치(40)의 작동하는 경로를 보면 먼저 자동차가 출발을 위하여 1속으로 변속하면, 1속 싱크로메시기구가 1속기어(10)쪽으로 이동하면서 싱크로메시기구에 고정되어 있는 부착기어(30)가 역회전방지장치(40)의 래칫휠 내부기어(41)와 맞물리게 되어 싱크로메시기구는 래칫휠과 일체로 회전하게 된다. 래칫휠은 래칫기어(42)와 폴(45)의 결합에 의하여 자동차가 전진할 때 구동축이 회전하는 방향과 같은 방향으로만 회전하도록 되어 있기 때문에 경사로에서 1속으로 변속(클러치 페달를 밟은 상태)한 상태에서 브레이크 페달에서 발을 떼더라도 자동차는 뒤로 밀리지 않는다.자동차가 경사로 위쪽으로 후진할 때 앞으로 밀리는(전진하는) 것을 방지하기 위하여 후진변속기어(50)에도 일정간격을 두고 부착기어(60)를 결합하여 고정하고, 후진변속기어(50)와 부착기어(60) 사이에 역회전방지장치(70)를 장착할 수 있다. 이때 역회전방지장치(70)는 자동차가 후진하는 방향으로만 회전할 수 있도록 래칫기어와 폴을 장치하여야 함은 물론이다.The reverse rotation prevention device 40 is composed of a reverse rotation prevention device case 43, 44 fixed to the case of the transmission as shown in Figure 4 and a ratchet wheel rotated inside the case, the ratchet wheel is An inner gear 41 that is engaged with the attachment gear 30 is formed therein, a ratchet gear 42 is formed around an outer center thereof, and a plurality of poles are formed inside the cases 43 and 44. 45 is coupled to the ratchet gear 42 in a state held by the spring 46. Since the ratchet gear 42 is formed only in the center of the outer circumference of the ratchet wheel, the left and right portions where the ratchet gear is not formed become the ratchet wheel shaft 49. The ratchet wheel shaft is combined with a plate bearing and lubricated to allow the ratchet wheel to rotate smoothly. In order to ensure that the inner gear 41 of the ratchet wheel and the attachment gear 30 of the synchro mesh mechanism can be smoothly engaged. As shown in Fig. 8, when the two gears mesh with each other, an inclined surface is formed on the gear blade. The pawls 45 coupled to the cases 43 and 44 of the reverse rotation preventing device 40 depend on the type of vehicle. It can be an appropriate number. For example, in the case of passenger cars, three or four poles are installed, while in the case of trucks and large buses, five or more can be installed to increase safety. The fixing part 48 which fixes a reverse rotation prevention device can also be set as an appropriate number as needed. FIG. 2 and FIG. 3 show the case where a transmission is in neutral. When shifting to the first speed, the first-speed synchro mesh mechanism moves to the left and the attachment gear 30 fixed thereto is also moved to the left to prevent reverse rotation by combining with the ratchet wheel internal gear 41 of the reverse rotation prevention device 40. The device will work. However, when the transmission is shifted to the neutral or the 1st speed, the reverse rotation prevention device does not operate because the reverse rotation prevention device is located between the attachment gear 30 and the slip 20. The reverse rotation prevention device 40 Looking at the working path of the first, if the vehicle shifts to the first speed for the start, the first gear synchro mechanism moves toward the first gear 10, the attachment gear 30 is fixed to the synchro mesh mechanism reverse rotation prevention device Engagement with the ratchet wheel internal gear 41 of 40 causes the synchro mesh mechanism to rotate integrally with the ratchet wheel. Since the ratchet wheel is rotated only in the same direction as the direction in which the drive shaft rotates when the vehicle moves forward by the combination of the ratchet gear 42 and the pole 45, the ratchet wheel is shifted at one speed on the ramp (the clutch pedal is pressed down). Even if you release the brake pedal in the state, the vehicle is not pushed backwards. To prevent the vehicle from being pushed forward (forwarding) when the vehicle reverses upward on the slope, the attachment gear 60 is spaced apart from the reverse gear 50. Combination and fixation, it is possible to install a reverse rotation prevention device 70 between the reverse gear 50 and the attachment gear (60). At this time, the reverse rotation prevention device 70 must be equipped with a ratchet gear and pole so that the car can only rotate in the reverse direction.

1속 변속시 싱크로메시기구를 이용하지 아니하고, 직접 1속 변속기어를 좌우로 움직여 직접 기어에 맞물리게 함으로써 변속하는 수동변속기의 경우에도 즉, 도2에서 싱크로메시기구가 없이 1속 기어(10)를 1속 변속기어로 사용하여 이를 좌우로 움직여 기어(90)에 연결함으로써 1속 변속을 하는 경우에도 1속 변속기어에 일정간격을 두고 부착기어를 결합하여 고정하고, 상기 역회전방지장치(40)를 1속 변속기어와 부착기어 사이에 위치시켜 변속기 케이스에 고정하여 만듬으로써 상기 설명에서와 같이 자동차가 언덕길에서 출발할 때 후방으로 밀리는 것을 방지할 수 있다.In the case of the manual transmission which shifts by directly engaging the gear by directly moving the first speed gear left and right without using a synchro mechanism when the first speed is shifted, that is, the first speed gear 10 without the synchro mesh mechanism is shown in FIG. By using the 1-speed gearbox to move it to the left and right to connect to the gear 90, even in the case of 1-speed shifting, the attachment gear is fixed at a certain interval to the 1-speed gearbox, and the reverse rotation preventing device 40 is fixed. By positioning between the 1st speed gear and the attachment gear, it is fixed to the transmission case to prevent the vehicle from being pushed backward when starting from the hill.

상기 구성에 의한 본 고안은 경사로 등에서 일시 정지후 출발하거나, 경사로 위쪽으로 후진하여 주차하고자 하는 등의 경우, 역회전방지장치에 의하여 경사로 아래 방향으로 밀리는 현상이 근본적으로 방지되므로 운전자가 1속 또는 후진 변속 상태에서 브레이크 페달에서 발을 떼어도 차량이 아래쪽으로 밀리지 않는다, 따라서, 비록 숙련되지 못한 운전자라도 편안한 마음으로 평지에서와 같이 가속페달 및 클러치페달을 조작할 수 있기 때문에 운전자의 부담을 줄이고, 안전운행에도 도움이 된다. 또 본 고안은 중립 또는 1속 이외로 변속된 상태에서는 작동하지 아니하므로 운행시 소음이나 추가 연료소모 등이 없고, 구조가 간단하여 제작경비가 적게 들며, 기존 변속기를 약간 변형하여 변속기 내부에 장착할 수 있는 등의 이점이 있다.The present invention by the above configuration is to start or stop after a temporary stop on the ramp, or to back up the ramp to park, etc., by the anti-rotation device is prevented from being pushed down the ramp by the anti-rotation device fundamentally prevents the driver from 1 speed or backward The vehicle will not be pushed down even if you step off the brake pedal while shifting, so even inexperienced drivers can comfortably operate the accelerator pedal and clutch pedal as if on a flat surface, reducing the operator's burden and ensuring safety. It also helps the operation. In addition, the present design does not operate in the state of shifting other than neutral or 1st speed, so there is no noise or additional fuel consumption during operation, and the structure is simple, so the production cost is low, and the existing transmission is slightly modified to be installed inside the transmission. And so on.
