본 고안은 자동차를 경사진 도로에서 상, 하향으로 주행중 잠시 정지한 후 전지이나 후진하는 경우 출발직전에 자동차 자중에 의해 역진되는 것을 방지하기 위한 자동차 역진방지장치에 관한 것이다.The present invention relates to a vehicle reverse prevention device for preventing the vehicle from being reversed by the weight of the vehicle immediately before departure when the vehicle or the reverse after stopping for a while while driving up and down on the inclined road.

종래 자동차를 경사진 도로에서 상, 하향으로 주행할때 잠시 정지하였다가 전진이나 후진하는 경우에는, 클러치 페달을 밟고 중립상태의 변속레버를 전진 또는 후진 상태로 한 후 클러치부터 발을 뗌과 동시에 가속페달을 밟아야 했기 때문에 초보운전자에게는 그 조작이 매우 어렵고 이에 따른 접촉사고의 우려가 있었으며, 숙련자가 조작하는 경우에는 가속 페달을 급속히 밟아야 하므로 그 순간 엔진에 과부하가 걸리게 되어 엔진의 작동이 멈추게되는 경우가 종종 발생하는 등 많은 문제점이 있었다.When driving a car up and down on an inclined road and moving forward or backward for a short time, press the clutch pedal, move the neutral shift lever forward or backward, and release the clutch and accelerate at the same time. Since it was necessary to step on the pedal, it was very difficult for a novice driver and there was a risk of contact. There were many problems, such as frequent occurrences.

또한 이러한 문제점을 해결하기 위하여 특허공고번호 제81-500호 자동차의 역진 제어장치와 출원중인 특허출원 제82-2778호 유로 조절 제어장치가 안출되어 있다.In addition, in order to solve this problem, a reverse control device of Patent Publication No. 81-500 and Patent Application No. 82-2778 flow control device is proposed.

그러나, 이들 장치는 첫째, 브레이크 작동 압과 클러치 작동압의 차이를 고려치 않았으며, 둘째, 대다수의 승용차에 적용되어 있는 기계식 클러치가 장착된 자동차에는 적용할 수 없고, 셋째, 역진제어 장치의 고장시 이를 대비한 비상수단이 없기 때문에 제어장치 부분의 어느 일부분이라도 고장이 나면 제어장치 뿐만 아니라 제동장치의 마비를 일으키게 되므로 커다란 위험을 초래하게되며, 그 장치를, 적용할 수 있는 차종에 제한을 받게되는 등 많은 문제가 있었다.However, these devices, first, do not take into account the difference between the brake operating pressure and the clutch operating pressure, and secondly, they cannot be applied to a vehicle equipped with a mechanical clutch applied to the majority of passenger cars, and third, failure of the reverse control device. Since there is no emergency means for this situation, if any part of the control unit breaks down, it causes paralysis not only of the control unit but also of the braking system, which causes a great danger, and the device is limited to the applicable vehicle models. There were many problems such as being.

본 고안은 이러한 종래의 제반문제점을 해소하고 일반적인 자동차 변속기에 편심포올(Pawl)을 장착하는 간단한 구조만으로 안전하고 확실한 역진방지효과를 얻을 수 있도록 하려는 것이다.The present invention is intended to solve the conventional problems and to obtain a safe and reliable reverse prevention effect only with a simple structure for mounting the eccentric pawl on a general automobile transmission.

이하 본 고안을 첨부도면에 따라서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안은, 도시한 바와 같이, 엔진으로부터의 동력을 전달받아 메인샤프트(1)를 회전시키는 메인드라이브기어(2)와, 메인드라이브기어(2)와 항상 맞물려 있는 카운터기어(3)와 카운터기어(3)에 항상 맞물려 있는 역회전 아이들기어(4)와 후진기어(5) 및 싱크로 나이져허브(6)로 구성되는 통상의 자동차용변속기에 있어서, 상기 역회전 아이들러기어(4)의 원통면(7)에 접촉되는 편심포올(8)을 축(9)으로서 변속기 하우징(10)에 장착하고 편심포올(8)을 원통면(7)에 접촉되는 방향으로 인장하는 스프링(11)을 설치한 것을 특징으로 하는 것이다.The present invention, as shown, the main drive gear (2) for receiving the power from the engine to rotate the main shaft (1), the counter gear (3) and the counter gear that is always engaged with the main drive gear (2) In the conventional automobile transmission comprising the reverse rotation idle gear 4, the reverse gear 5, and the synchronizer hub 6, which are always in engagement with (3), the cylindrical surface of the reverse rotation idler gear 4 Mounting the eccentric fool (8) in contact with the (7) to the transmission housing (10) as a shaft (9) and the spring (11) for tensioning the eccentric fool (8) in the direction in contact with the cylindrical surface (7) It is characterized by.

미설명부호(12)(13)(14)는 각각 1단, 2단, 3단 변속기어이며, (15)는 클러치 릴리스베어링이고, (16)은 싱크로나이져 슬리브이다.Reference numerals 12, 13 and 14 are first, second and third gears, respectively, 15 is a clutch release bearing and 16 is a synchronizer sleeve.

먼저 자동차변속기의 작동을 설명하면 엔진의 동력을 싱크로나이져 슬리브(16)을 좌우로 이동시켜 변속기어 (12)(13)(14)와 싱크로나이져 허브(6)를 연결시키는 것에 의하여 메인드라이브기어(2)를 개재하여 메인샤프트(1)에 전달되며, 후진기어(5)를 좌우로 이동시켜 역회전 아이들러기어 (4)와 계합시키는 것에 의하여 메인샤프트(1)를 메인 드라이브기어 (2)와 반대방향으로 회전시켜 후진을 행하는 것이다.First, the operation of the automobile transmission will be described by synchronizing the power of the engine to move the sleeve 16 to the left and right to connect the transmission gears 12, 13, 14 and the synchronizer hub 6 to the main drive. It is transmitted to the main shaft 1 via the gear 2, and the main shaft 1 is connected to the main drive gear 2 by moving the reverse gear 5 from side to side and engaging with the reverse rotation idler gear 4. To reverse in the opposite direction by rotating.

또 변속위치에 있거나 중립위치에 있거나 메인드라이브기어(2)와 카운터기어(3)와 역회전 아이들러기어(4)는 항상맞물린 상태에 있으며, 중립위치에서는 메인드라이브기어(2)와 메인샤프트(1)은 연결되지 않고, 전진변속위치에서는 싱크로 나이져 슬리브 (16)과 허브(6)에 의하여 메인드라이브기어(2)와 메인샤프트(1)가 연결되며, 후진변속위치에서는 후진기어(5)가 메인샤프트(1)에 연결되고 역회전 아이들러기어 (4)와 맞물려서 뒷 바퀴를 구동시킨다.In the shifting position or in the neutral position, the main drive gear (2), the counter gear (3) and the reverse idler gear (4) are always in the engaged state, and in the neutral position, the main drive gear (2) and the main shaft (1). ) Is not connected, and the main drive gear 2 and the main shaft 1 are connected by the synchronizer sleeve 16 and the hub 6 in the forward shift position, and the reverse gear 5 in the reverse shift position. It is connected to the main shaft (1) and meshes with the reversing idler gear (4) to drive the rear wheels.

이때 클러치가 연결되면 변속기어가 전진위치이든 후진위치이든 중립 위치이든 엔진의 회전방향이 항상 반시계 방향이므로, 메인드라이브기어(2)는 반시계방향으로, 카운터기어(3)은 시계방향으로, 역회전 아이들러기어(4)는 반시계방향으로 회전한다.At this time, when the clutch is connected, whether the transmission gear is in the forward position, the reverse position, or the neutral position, the rotation direction of the engine is always counterclockwise. Therefore, the main drive gear 2 is counterclockwise, and the counter gear 3 is clockwise. The rotary idler gear 4 rotates counterclockwise.

이와 같이 변속기는 전진 및 후진 변속을 행하는 것이다.In this way, the transmission shifts forward and backward.

다음 본 고안의 작용효과를 설명한다.Next, the effect of the present invention will be described.

위에서 설명한 바와 같이, 연회전 아이들러기어(4)는 변속 상태에 관계 없이 반시계방향으로 회전되므로 정상운행시에는 편심포올(8)은, 제3(a)도에 도시한 바와 같이, 편심포올(8)과 역회전아이들러기어(4)의 원통면(7)에 생기는 마찰력 μN'(여기서 μ는 원통면(7)과 포올(8)의 마찰계수, N'는 압력이다)에 의하여 시계방향으로 회전시키는 힘을 받게되어 역회전아이들러기어(4)가 제동력을 받지 않고 자연스럽게 회전하게되어 변속상태에 따라 엔진의 동력이 메인샤프트(1)에 전달되어 후륜을 구동하게 된다.As described above, since the banquet idler gear 4 is rotated counterclockwise irrespective of the shift state, the eccentric fool 8 is the eccentric fool 8 as shown in FIG. 3 (a) during normal operation. 8) and the frictional force μN 'generated on the cylindrical surface 7 of the reversing idler gear 4, where μ is the friction coefficient between the cylindrical surface 7 and the pole 8, N' is the pressure. The rotating idler gear 4 is naturally rotated without the braking force so that the power of the engine is transmitted to the main shaft 1 according to the shift state to drive the rear wheels.

또한 클러치(15)가 해방되고 기어변속 상태에 있을 경우에는 메인드라이브기어(2)와 메인샤프트(1) 및 후륜은 서로 연결되어 있으므로(4)의 회전방향이 결정된다.In addition, when the clutch 15 is released and in the gear shift state, the rotation direction of the main drive gear 2, the main shaft 1, and the rear wheels are connected to each other (4).

즉, 클러치릴리스 베어링(15)이 클러치를 해방시켜 엔진의 동작이 변속기에 전달되지 않는 상태에서 기어가 전진위치에서 후륜이 뒤로 굴러가려 하거나, 후진 위치에서 후륜이 앞으로 굴러가려고 하면, 역회전 아이들러기어(4)는 시계방향으로 회전하게된다.That is, when the clutch release bearing 15 releases the clutch and the engine operation is not transmitted to the transmission, when the rear wheel is going to roll backward at the forward position or the rear wheel is going to roll forward at the reverse position, the reverse idler gear 4 will rotate clockwise.

따라서 경사진 도로를 상향 전진 운행시나 하향후진 운행시 잠시 멈춘 다음 재출발하려할 경우 브레이크페달에서 밟을 때는 순간자동차의 차중에 의하여 후륜이 후진 또는 전진하려 하더라도 역회전 아이들러기어(4)가 제3(b)도에 도시한 바와 같이, 시계방향으로 회전되므로 역회전아이들러기어(4)의 원통면(7)과 편심포올(8)의 외주면 사이에 발생되는 마찰력 μN에 의하여 편심포올(8)에는 반시계 방향으로 모우멘트 μN.r.cosθ가 작용되어 역회전 아이들러기어(4)의 시계방향 회전을 방지하게 된다.Therefore, if you try to restart after stopping for a while on an uphill forward or downward backward driving, when you step on the brake pedal, even if the rear wheel is going to go backward or forward by the weight of the momentary vehicle, the reverse idler gear (4) does not support the third (b). As shown in FIG. 6, the counterclockwise rotation is caused by the friction force μN generated between the cylindrical surface 7 of the reverse rotation idler gear 4 and the outer circumferential surface of the eccentric polyol 8 as shown in FIG. The moment μN.r.cosθ is applied in the direction to prevent the clockwise rotation of the reverse rotation idler gear 4.

이때 편심포올(8)에 걸리는 반시계 방향의 모우멘트 μN.r.cosθ를 역회전 아이들러기어(4)의 시계방향 모우멘트 N.r.sinθ보다 크게하여야하며, 따라서 편심포올(8)과 역회전 아이들러기어(4)의 원통면(7)의 외주면간의 마찰계수 μ를 μ> tanθ로 설정하면 역전을 확실히 방지할 수 있다.At this time, the counterclockwise moment μN.r.cosθ applied to the eccentric fool 8 should be larger than the clockwise moment Nrsinθ of the reverse rotation idler gear 4. Therefore, the eccentric fool 8 and the reverse rotation idler gear If the friction coefficient μ between the outer peripheral surfaces of the cylindrical surface 7 of (4) is set to μ> tanθ, reversal can be reliably prevented.

이상과 같이 본 고안은 통상의 자동차 변속기에 편심포올(8)과 스프링(11)을 설치하는 것만으로서 경사진 도로에서 자동차 자중에 의한 역진을 확실하게 방지할 수 있으며, 구조가 간단하여 원가를 절감할 수 있고, 기존변속기에도 간단하여 원가를 절감할 수 있고, 기존 변속기에도 간단하게 적용할 수 있으며, 브레이크 계통이나 엔진에 과부하가 걸릴염려가 없고, 기계식 클러치 장치나 유압식 클러치 장치가 장착된 차종에 모두 적용할 수 있는 등 지대한 효과가 있는 것이다.As described above, the present invention can reliably prevent backlash due to the weight of the vehicle on a sloping road by simply installing the eccentric pole 8 and the spring 11 in a normal vehicle transmission, and the structure is simple, and the cost is reduced. It is possible to reduce the cost by being simple to the existing transmission, and to be easily applied to the existing transmission, and there is no fear of overloading the brake system or the engine, and to the models equipped with the mechanical clutch or the hydraulic clutch device. All of these can be applied to such a great effect.
