본 발명은 차체 하중에 따라 마스터 실린더 피스톤과 로드간의 간격을 좁혀지게 하므로서 제동력 작동시점을 변하도록하여 적절한 제동성을 확보할 수 있도록 하는 차량 중량에 따른 가변 유압구조에 대한 것이다.The present invention relates to a variable hydraulic structure according to the weight of the vehicle to ensure the appropriate braking property by changing the braking force operating time while narrowing the distance between the master cylinder piston and the rod according to the body load.
일반적으로 유압식 브레이크는 브레이크 페달의 조작에 의해 브레이크 부스터를 작동시키게 되면 푸쉬로드가 밀리면서 마스터 실린더의 피스톤에 의해서 유압을 발생시키도록 하는 것이다.In general, the hydraulic brake is to operate the brake booster by the operation of the brake pedal to push the push rod to generate the hydraulic pressure by the piston of the master cylinder.
즉 운전자의 페달 조작력에 의해 진공압으로 푸쉬로드를 밀어 마스터 실린더의 유압에 의해서 제동작동이 이루어지도록 하는 것이다.In other words, the push rod is pushed by vacuum pressure by the pedal operation force of the driver so that the braking operation is performed by the hydraulic pressure of the master cylinder.
한편 기존 브레이크 장치는 차량의 중량에 관계없이 제동력이 작동토록 하는 구성이며, 단지 중량에 따른 노면과의 마찰력이 자연 증가하면서 제동성이 좀더 향상되는 미세한 효과만 있을 뿐이다.On the other hand, the conventional brake device is configured to allow the braking force to operate regardless of the weight of the vehicle, but only a slight effect of improving the braking property as the frictional force with the road surface increases naturally.
하지만 공차인 경우에는 기존의 브레이크 장치에 의해서도 제동력 작동시간이 충분하여 비교적 좁은 차 간거리에서도 안전한 제동성이 유지되지만 승차인원이 많아지게 되면 공차인 경우보다 제동거리가 길어져야 하므로 정확한 안전거리 확보에 어려움이 많았다.However, in the case of tolerance, the braking force operating time is sufficient even with the existing brake system, so that the safe braking is maintained even at relatively narrow distances. There were a lot.
특히 운전자가 안전 거리 확보에 판단을 잘못하게 되는 경우에는 바로 사고와 연결되게 되는 문제점이 있다.In particular, when a driver makes a mistake in securing a safety distance, there is a problem that is directly connected to an accident.
이에 본 발명은 상기와 같은 차량의 중량에 따라 제동거리를 항상 일정하게 유지할 수 있도록 하는 브레이크 유압 구조를 제공코자 하는데 목적이 있는 것이다.Accordingly, an object of the present invention is to provide a brake hydraulic structure that can maintain a constant braking distance according to the weight of a vehicle as described above.
상기의 목적에 따라 본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings the present invention according to the above object.
도면 제1도는 본 발명에 따른 실시예 구조를 도시한 개략 단면도로서, 상기의 도면에서 보는 바와 같이 본 발명은 크게 중압 실린더(30)와 푸쉬 실린더(40)와 압축 스프링(50)으로 이루어지는 구성이다.1 is a schematic cross-sectional view showing an embodiment structure according to the present invention. As shown in the above drawings, the present invention is composed of a medium pressure cylinder 30, a push cylinder 40, and a compression spring 50. .
즉 상기 중압 실린더(30)는 상단부가 차체 프레임에, 하단부가 차축에 각각 고정착설되어 차체의 중량이 증가함에 따라 유압이 증강되도록 하는 것으로 상부는 가압부(31)이고, 하부는 수압부(32)로 형성되어 차체 프레임에 상단부가 고정된 가압부(31)가 차체의 중량증감에 따라 승강하므로서 차축에 하단부가 고정된 수압부(32)내 오일의 압력을 달리 형성시키게 되는 것이다.That is, the medium pressure cylinder 30 is fixed to the upper end of the body frame, the lower end is fixed to the axle, so that the hydraulic pressure is increased as the weight of the vehicle increases, the upper portion is the pressurizing portion 31, the lower portion is the hydraulic portion 32 The pressure portion 31 formed at the upper end portion is fixed to the vehicle body frame in accordance with the increase or decrease of the weight of the vehicle body, thereby differently forming the pressure of the oil in the hydraulic pressure portion 32 having the lower end portion fixed to the axle.
또한 상기 가압부(31)와 수압부(32)의 외주면간으로는 리턴스프링(33)이 장설되도록 하여 중량의 감소에 따른 따른 복운을 신속하게 수행되도록 하는 것이다.In addition, the return spring 33 is installed between the outer circumferential surface of the pressing portion 31 and the pressure receiving portion 32 so as to quickly perform the luck according to the weight decrease.
상기의 푸쉬 실린더(40)는 상기 중압 실린더(30)로부터 공급되는 유압에 의해 로드(42)가 인출되도록 하는 연동구조로서, 오일이 유입되는 바디(41)는 후단부가 브레이크 부스터(20)와 연결되며, 상기 바디(41)의 전단부로는 유압에 의해 인출입되는 로드(42)가 끼워지도록 한 구성이다.The push cylinder 40 is an interlocking structure in which the rod 42 is drawn out by the hydraulic pressure supplied from the medium pressure cylinder 30, and the body 41 into which oil is introduced is connected to the brake booster 20 at the rear end thereof. As the front end of the body 41, the rod 42 drawn out by the hydraulic pressure is fitted.
특히 상기 로드(42)에는 외주면으로 걸림턱(42A)이 형성되는 형상이다.In particular, the rod 42 has a shape in which the engaging jaw 42A is formed on the outer circumferential surface.
또한 상기의 압축 스프링(50)은 마스터 실린더(10)의 피스톤(11)후단부로 돌출시킨 피스톤 스토퍼(12)와 상기 로드(42)의 외주면으로 돌설시킨 걸림턱(42A)간으로 탄설되어 상기 중압 실린더(30)로부터 유도되는 유압을 반감시켜 과도한 로드(42)작동을 방지토록 하는 것이다.In addition, the compression spring 50 is installed between the piston stopper 12 protruding to the rear end of the piston 11 of the master cylinder 10 and the engaging jaw 42A protruding to the outer circumferential surface of the rod 42 and the medium pressure. It is to halve the hydraulic pressure induced from the cylinder 30 to prevent excessive rod 42 operation.
한편 상기와 같은 압축 스프링(50)과 함께 중압 실린더(30)와 푸쉬 실린더(40)간의 오일 튜브(34)로 원판에 다수개의 홀(51)을 천공시킨 감속 플레이트(60)를 형성시켜 급속도로 공급되는 유압을 보다 완화되도록 하므로서 보다 유연한 로드(42) 작동을 유도되게 할 수도 있다.Meanwhile, with the compression spring 50 as described above, the oil tube 34 between the medium pressure cylinder 30 and the push cylinder 40 forms a deceleration plate 60 in which a plurality of holes 51 are drilled in the disc to rapidly. It is also possible to induce more flexible rod 42 operation by making the hydraulic pressure supplied to be more relaxed.
이하 상기 구성에 따른 본 발명의 작동과 효과는 하기와 같다.Operation and effects of the present invention according to the above configuration are as follows.
제2도는 본 발명이 적용된 사용상태도이다.2 is a use state diagram to which the present invention is applied.
브레이크 부스터(20)와 마스터 실린더(10)를 연결시키게 되면 본 발명의 로드(42)전단부와 마스터 실린더(10)내 피스톤(11) 후단부간에는 일정한 유격이 형성되게 된다.When the brake booster 20 and the master cylinder 10 are connected, a predetermined clearance is formed between the front end of the rod 42 and the rear end of the piston 11 in the master cylinder 10 of the present invention.
상기와 같은 유격은 공차일때를 기준으로 설정되며, 차량의 승차인원이 증가한다거나 짐이 실리게 되면 차량 중량이 증가되면서 본 발명의 중압 실린더(30)가 작동하게 된다.The above clearance is set on the basis of the tolerance, and when the number of passengers of the vehicle increases or loads the vehicle, the medium pressure cylinder 30 of the present invention operates while the vehicle weight increases.
즉 상기 중압 실린더(30)의 가압부(31)가 눌려지게 되면 수압부(32)내의 유압이 서서히 증가하면서 유압을 오일 튜브(34)를 통해 푸쉬 실린더(40)의 바디(41)측으로 공급시키게 된다.That is, when the pressurizing portion 31 of the medium pressure cylinder 30 is pressed, the hydraulic pressure in the hydraulic pressure portion 32 is gradually increased to supply the hydraulic pressure to the body 41 side of the push cylinder 40 through the oil tube 34. do.
푸쉬 실린더(40)의 바디(41)측으로 유입된 유압은 전방의 로드(42)를 압축 스프링(50)의 탄력을 이기고 일정한 길이만큼 인출시키게 되는 것이다.The hydraulic pressure introduced to the body 41 side of the push cylinder 40 is to pull the front rod 42 to the predetermined length to overcome the elasticity of the compression spring 50.
이렇게 인출되는 로드(42)는 마스터 실린더(10)내의 피스톤(11)과 더욱 근접하게 되므로 공차일때에는 브레이크 페달 조작에 따른 제동 응답 시간이 빨라지게 되는 것이다.The rod 42 drawn out in this way is closer to the piston 11 in the master cylinder 10, so that the braking response time according to the brake pedal operation is faster when the tolerance is achieved.
제동 응답 시간이 빨라지게 되는 것은 제동 시간이 보다 길어지게 되는 것인 바 결과적으로 공차일때와 제동거리는 동일한 상태로서 유지가 되게 되는 것이다.The faster the braking response time is, the longer the braking time is. As a result, the braking distance and the braking distance are maintained in the same state.
따라서 운전자는 차량의 중량이 증가할때마다 제동 거리의 확보를 위한 찻간 안전거리에 변동을 주지 않으면서 운전을 할 수 있게 되므로 운전자의 주행성을 향상시키게 되는 것이며, 특히 운전자가 아닌 차량 스스로 차량 중량에 따른 제동력 조절로 항상 일정한 제동거리를 유지시킬 수가 있게 되므로 안전한 주행을 할 수가 있게 되는 것이다.Therefore, the driver can drive without changing the safety distance between the cars to secure the braking distance whenever the weight of the vehicle increases, thereby improving the driver's driving ability, especially the vehicle itself, not the driver It is possible to maintain a constant braking distance by adjusting the braking force according to the safe driving.
그러므로 본 발명은 운전자가 차량 중량에 따른 안전거리 확보에 신경을 쓰지 않아도 되며, 특히 운전자의 안전 거리 오판으로 인한 사고 발생 가능성을 방지시키게 되므로 보다 안전한 차량 운행을 제공하게 되는 매우 유용한 효과가 있는 것이다.Therefore, the present invention does not have to worry about the driver to secure the safety distance according to the weight of the vehicle, and in particular prevents the possibility of an accident caused by the driver's safety distance misjudgment, thereby providing a very safe vehicle operation.
