Field of the Invention The present invention relates to a vehicle load detector, comprising: a pressure reducing valve (6) installed in a frame (1) of a vehicle body so that the valve rod (5) forms a vertical direction, and a guide (7) installed in a vertical direction on the rear axle (2). ) And one side is coupled to the valve rod 5 and the other side is coupled to the guide 7 to operate the pressure reducing valve 6 while being lowered along the guide 7 in proportion to the weight of the load.

Description
본 발명은 차량의 하중를 감지하는 장치에 관한 것으로, 특히 화물칸의 중량에 따라 승강되는 이동체를 매개로 압력을 조절할 수 있도록 되어 압력손실을 최소화하도록 된 차량하중 감지기에 관한 것이다.The present invention relates to an apparatus for detecting a load of a vehicle, and more particularly, to a vehicle load detector configured to minimize pressure loss by adjusting a pressure via a moving object that is lifted and lowered according to a weight of a cargo compartment.
짐을 적재하는 화물차량에 있어서, 짐을 실지 않은 공차상태에서는 리어부분이 프론트부분보다 상대적으로 하중이 덜 가해져 가볍기 때문에 브레이크를 동작시키게 되면 리어휠에서 스키드마크가 발생되면서 차체가 한쪽 방향으로 회전을 하게 된다.In a load-carrying cargo vehicle, in the unloaded tolerance state, the rear part is lighter because it is relatively less loaded than the front part. When the brake is operated, a skid mark is generated on the rear wheel and the body rotates in one direction. .
즉, 화물차량에 설치되는 브레이크는 대개 전륜과 후륜을 동시에 구속하도록 되어 있어서 화물을 적재하지 않고 브레이크를 동작시키면 타이어와 노면간의 마찰계수가 상대적으로 낮은 쪽에서 차체가 회전되게 된다.In other words, the brakes installed in the freight vehicle are generally designed to restrain the front wheel and the rear wheel at the same time, so that when the brake is operated without loading the cargo, the vehicle body rotates at the relatively low coefficient of friction between the tire and the road surface.
이를 방지하기 위하여 종래에도 도 3에 도시된 것과 같이 차체의 프레임(1)과 리어액슬(2)사이에 소정장력을 갖는 코일스프링(3)이 설치되고, 이 코일스프링(3)이 밸브레버(4)를 동작시켜 밸브압력을 조절하므로써 차체높이가 중립상태가 유지되도록 하고 있다.In order to prevent this, a coil spring 3 having a predetermined tension is conventionally installed between the frame 1 and the rear axle 2 of the vehicle body as shown in FIG. 3, and the coil spring 3 is a valve lever ( 4) is operated to adjust the valve pressure to maintain the vehicle height in neutral.
이에 따라 공차인 상태에서 급브레이크를 밟았을 때 차량의 뒷쪽으로 앞부분보다는 상대적으로 작은 제동력이 가해지도록 조절하여 후륜에 설치되는 브레이크장치에서 록 현상 즉, 스키드마크가 찍힐 정도로 차량이 급제동되는 것을 방지할 수 있게 된다.Accordingly, when a sudden brake is applied in a tolerated state, a braking force is applied to the rear of the vehicle, rather than to the front, so that the brake device installed on the rear wheel prevents the braking, that is, the skid mark is rapidly applied. It becomes possible.
그런데, 상기와 같은 구조로 된 종래의 감지기는, 장기간 사용함에 따라 코일스프링(3)의 장력에 변화가 생기게 되면, 차체의 거동에 따라 밸브로드(4)를 제대로 동작시킬 수 없게 되어 밸브압력이 적절하게 제어되지 못하게 되며, 이로 인해 급제동시 차체가 회전되는 현상이 발생된다는 문제점이 있었다.However, in the conventional sensor having the above-described structure, if the tension of the coil spring 3 changes due to long-term use, the valve rod 4 cannot be properly operated according to the behavior of the vehicle body, and the valve pressure is reduced. It may not be properly controlled, which causes a problem that the vehicle body is rotated during sudden braking.
이에 본 발명은 상기와 같은 문제를 해결하기 위하여 발명된 것으로, 화물칸의 중량에 따라 승강되는 이동체를 매개로 밸브압력을 조절할 수 있도록 되어 급제동시에도 후륜의 브레이크에서 록현상이 발생하는 것을 효과적으로 방지할 수 있도록 된 차량하중 감지기를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, it is possible to adjust the valve pressure via the moving body to be lifted according to the weight of the cargo compartment to effectively prevent the occurrence of the lock phenomenon in the brake of the rear wheel during sudden braking. It is an object of the present invention to provide a vehicle load detector that can be used.
상기와 같은 목적을 달성하기 위한 본 발명의 차량하중 감지기는, 차체의 프레임에 밸브로드가 수직방향을 이루도록 설치되는 감압밸브와, 리어액슬위에 수직방향으로 설치되는 가이드와, 일측은 상기 밸브로드와 결합되고 타측은 상기 가이드와 결합되어 적재하중의 중량에 비례하는 만큼 상기 가이드를 따라 승하강되면서 감압밸브를 작동시켜 밸브압력을 조절하도록 하는 이동체로 구성되는 것을 특징으로 한다.The vehicle load sensor of the present invention for achieving the above object, the pressure reducing valve is installed in the frame of the vehicle body in a vertical direction, the guide installed in the vertical direction on the rear axle, and one side is the valve rod and The other side is coupled to the guide is characterized in that it is composed of a moving body to adjust the valve pressure by operating the pressure reducing valve while moving up and down along the guide in proportion to the weight of the load.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 감압밸브의 개략적인 구성도이고, 도 2는 도 1의 A위치에서 본 요부단면도로서, 본 발명은 도면에 도시된 것과 같이, 차체의 프레임(1)에 밸브로드(5)가 수직방향을 이루도록 감압밸브(6)가 설치되고, 리어액슬(2)위에 수직방향으로 가이드(7)가 설치되며, 이 가이드(7)를 매개로 상하로 이동가능하도록 이동체(8)가 설치되어 있다.FIG. 1 is a schematic configuration diagram of a pressure reducing valve according to the present invention, and FIG. 2 is a sectional view of a main part viewed from the position A of FIG. 1, and the present invention, as shown in the drawing, includes a valve rod ( A pressure reducing valve 6 is installed so that 5) is in a vertical direction, and a guide 7 is installed in the vertical direction on the rear axle 2, and the movable body 8 is movable up and down via the guide 7. Is installed.
그리고 상기 가이드(7)에는 수직방향으로 안내레일(9)이 형성되고, 상기 이동체(8)의 일측에는 수직방향으로 돌출부(도시되지 않음)가 형성되어, 이 돌출부가 상기 안내레일(9)에 끼워짐으로써 상기 이동체(8)가 가이드(7)를 따라 수직방향으로 이동될 수 있도록 되어 있다.A guide rail 9 is formed in the guide 7 in the vertical direction, and a protrusion (not shown) is formed in one side of the movable body 8 in the vertical direction, and the protrusion is formed in the guide rail 9. By being fitted, the movable body 8 can be moved in the vertical direction along the guide 7.
한편, 상기 이동체(8)의 다른쪽 면에는 소정각도로 테이퍼부(10)가 형성되어 있는 바, 이 테이퍼부(10)는 차체의 중량에 따라 프레임(1)과 리어액슬(2)이 수직방향으로 거동될 때 거동범위에 따라 밸브로드(5)를 동작시키게 된다.On the other hand, the tapered portion 10 is formed on the other surface of the movable body 8 at a predetermined angle, and the tapered portion 10 has the frame 1 and the rear axle 2 perpendicular to each other according to the weight of the vehicle body. When operating in the direction to operate the valve rod 5 in accordance with the range of motion.
다음에는 이상과 같이 구성된 차량하중 감지기(11)의 동작에 대해 설명한다.Next, the operation of the vehicle load detector 11 configured as described above will be described.
공차인 상태에서는 프레임(1)을 기준으로 하여 리어액슬(2)이 상대적으로 하강하게 되므로, 이 리어액슬(2)에 고정된 이동체(8)가 가이드(7)를 따라 함께 하강하게 되고, 이에 따라 밸브로드(5)는 테이퍼부(10)의 경사각도 만큼 상기 가이드(7)쪽을 향하는 방향으로 이동되면서(즉, 도 1에 도시된 상태에서 우측방향으로 이동되면서) 감압밸브(6)를 동작시켜 밸브압력을 조절하게 되며, 이로 인해 차체는 중립을 이룰 수 있게 된다.In the state of tolerance, since the rear axle 2 is relatively lowered relative to the frame 1, the movable body 8 fixed to the rear axle 2 is lowered along the guide 7 together. Accordingly, the valve rod 5 moves in the direction toward the guide 7 by the inclination angle of the tapered portion 10 (that is, while moving to the right in the state shown in FIG. 1) to reduce the pressure reducing valve 6. By operating the valve pressure, which makes the body neutral.
반대로, 적차인 상태에서는 프레임(1)을 기준으로 하여 리어액슬(2)이 상대적으로 상승하게 되므로, 이 리어액슬(2)에 고정된 이동체(8)가 가이드(7)를 따라 함께 상승하게 되고, 이에 따라 밸브로드(5)는 테이퍼부(10)의 경사각도 만큼 상기 프레임(1)쪽을 향하는 방향으로 이동되면서(즉, 도 1에 도시된 상태에서 좌측방향으로 이동되면서) 감압밸브(6)를 동작시켜 밸브압력을 조절하게 되며, 이로 인해 차체는 중립을 이룰 수 있게 된다.On the contrary, since the rear axle 2 is relatively raised with respect to the frame 1 in the vehicle position, the movable body 8 fixed to the rear axle 2 is raised along the guide 7 together. Accordingly, the valve rod 5 is moved in the direction toward the frame 1 by the inclination angle of the tapered portion 10 (that is, while moving to the left in the state shown in FIG. 1) the pressure reducing valve 6 ) To regulate the valve pressure, which makes the body neutral.
한편, 상기 이동체(8)에 형성된 테이퍼부(10)는 리어액슬(2)의 거동상태에 따라 감압밸브(6)의 동작을 직접 제어하는 역할을 수행하므로 그 경사각을 적절하게 조절해 주어야 하며, 경사각을 적절하게 조절하면 화물칸의 용적에 관계없이 폭 넓게 적용할 수 있는 잇점이 있게 된다.On the other hand, the tapered portion 10 formed on the movable body 8 serves to directly control the operation of the pressure reducing valve (6) according to the behavior of the rear axle (2), so that the inclination angle should be adjusted appropriately, Properly adjusting the angle of inclination has the advantage of being widely applicable regardless of the cargo volume.
이상 설명한 것과 같이 본 발명에 따르면, 압력손실 없이 화물칸의 중량에 따라 적절하게 밸브압력을 조절할 수 있게 됨으로써, 급제동시 후륜의 브레이크에서 록현상이 발생하는 것을 효과적으로 방지할 수 있게 되고, 이에 따라 안전사고를 예방할 수 있는 효과가 있게 된다.As described above, according to the present invention, the valve pressure can be adjusted appropriately according to the weight of the cargo compartment without pressure loss, thereby effectively preventing the occurrence of the lock phenomenon in the brake of the rear wheel during sudden braking, and thus a safety accident. Will be effective to prevent.
