본 발명은 험로 내구시험로의 서스펜션 냉각시스템에 관한 것으로, 특히 신차종개발기간을 단축하기 위하여 실시하는 험로 내구시험을 실시하는 무인 내구 시험차량의 쇽업저버를 자동으로 냉각시켜 줄 수 있도록 된 험로 내구시험로의 서스펜션 냉각시스템에 관한 것이다.The present invention relates to a suspension cooling system for a test road endurance test furnace, and particularly, to provide an automatic cooling of the shock absorber of an unmanned endurance test vehicle that carries out a test road endurance test conducted to shorten a new vehicle model development period. A suspension cooling system in a test furnace.

일반적으로, 험로 내구시험은 도로의 조건이 험하여 운전자가 신체에 많은 충격을 받아 몸을 상하는 사례가 빈번하여 험로 주행용 내구 시험차량은 무인화하는 추세이다.In general, in the case of the rough road endurance test, the road condition is so severe that the driver is often shocked by the body and the body is hurt, so the endurance test vehicle for the rough road driving is unmanned.

또한, 내구시험을 위하여 험로를 주행하면 서스펜션의 쇽 업저버가 과격한 운동을 하여 쇽 업저버 내부 오일의 온도가 급상승하고, 쇽업저버 내부의 피스톤 및 내부 부품들이 열에 의하여 손상을 당하며, 오일의 온도가 상승하여 댐핑포스(Damping Force)도 약화되어 많은 충격을 흡수하지 못하므로 쇽 업져버가 조기에 파손이 되고, 이에 따라 차체도 시험목적에 맞지 않는 과도한 충격과 함께 내구력을 정확히 파악하기 어려운 파손을 당하게 된다.In addition, if you drive the rough road for endurance test, the shock absorber moves sharply, the temperature of the oil inside the shock absorber rises rapidly, the piston and internal parts inside the shock absorber are damaged by heat, and the oil temperature rises. Damping force is also weakened to absorb a lot of shock, so the shock absorber is damaged prematurely, and thus the car body suffers excessive shock that is not suitable for the test purpose and damage that is difficult to pinpoint the durability.

이에 따라 험로 내구시험을 위해서는 쇽 업져버 냉각장치가 필히 가동되어야 하는 것으로, 종래에는 냉각수 탱크와 냉각수 분사용 펌프 및 배터리를 차량에 탑재하였다.Accordingly, the shock absorber cooling apparatus must be operated for the rough road durability test. In the related art, a coolant tank, a coolant spray pump, and a battery are mounted on a vehicle.

따라서, 종래에는, 주행중에 차량 실내에 적재된 냉각수탱크의 물을 냉각수 분사용 펌프를 가동시켜 쇽업저버에 분사하여 냉각하거나, 또는 차량을 정차시켜 놓고 호스로 물을 뿌려 쇽업저버를 냉각시켰다.Therefore, in the related art, water in a coolant tank loaded in a vehicle interior while driving is cooled by spraying a coolant injection pump on a shock absorber or cooling the shock absorber by stopping the vehicle and spraying water with a hose.

그러나 종래에는, 차량 내부에 냉각수탱크와 냉각수 분사용펌프 및 베터리를 탑재하게 되므로 차량의 중량에 관한 시험조건을 정확히 관리할 수 없고, 차량에 탑재한 냉각수탱크의 물을 다 사용하면 재충진해야 하므로 불필요한 시간을 과다하게 소비하며, 차량을 정차시켜 놓고 호스로 물을 뿌려 쇽업저버를 냉각할 경우 확실한 냉각효과를 얻지 못함은 물론, 차량을 정차시켜 놓게 되어 정확한 측정 데이타를 얻을 수 없는 문제점이 있었다.However, in the related art, since the coolant tank, the coolant injection pump, and the battery are mounted inside the vehicle, it is impossible to accurately manage the test conditions regarding the weight of the vehicle. Excessive time wasted excessively, and when the vehicle is stopped and water is sprayed with a hose to cool the shock absorber, there is a problem that the vehicle is stopped and accurate measurement data is not obtained.

본 발명의 목적은, 특히 신차종 개발기간을 단축하기 위하여 실시하는 험로 내구시험을 실시하는 무인 내구 시험차량의 쇽업저버를 자동으로 냉각시켜 줄 수 있는 험로 내구시험로의 서스펜션 냉각시스템을 제공하기 위한 것이다.SUMMARY OF THE INVENTION An object of the present invention is to provide a suspension cooling system for a humgro endurance test furnace that can automatically cool the shock absorber of an unmanned endurance test vehicle that performs the ruggedness endurance test, in particular, to shorten the development period of a new vehicle. will be.

도면과 같이, 시험로(200)의 일부에 내구차량(100)의 주행방향으로 다수의 압력관(10)을 내설하고, 상기 압력관(10)의 좌, 우에 분사노즐(12)을 바깥 방향을 향하도록 경사지게 설치하며, 상기 압력관(10)의 끝단에 밸브(14)를 연결, 설치하고, 상기 압력관(10)에 펌프(20)를 연결, 설치하며, 상기 펌프(20)에 여과망이 설치된 흡수구(22)을 연결, 설치하고, 상기 흡수구(22)를 시험로(200) 일측에 설치한 저수조(50) 저면에 설치하며, 상기 시험로(200) 좌, 우의 일측에 차량위치감지센서(30)를 설치하고, 상기 시험로(200)의 상부면에 집수로(52)를 형성하며, 상기 집수로(52)의 상부에 쇠창살발판(54)을 설치하여 구성한다.As shown in the drawing, a plurality of pressure tubes 10 are installed in a part of the test path 200 in the driving direction of the durable vehicle 100, and the injection nozzles 12 are directed outwardly to the left and right of the pressure tube 10. It is installed to be inclined so as to connect and install the valve 14 to the end of the pressure pipe 10, the pump 20 is connected to and installed in the pressure pipe 10, the absorption port is installed in the filter network (20) ( 22) to connect and install, the absorption port 22 is installed on the bottom surface of the reservoir 50 installed on one side of the test furnace 200, the vehicle position sensor 30 on one side of the test passage 200, left and right To install, to form a water collecting passage 52 on the upper surface of the test passage 200, and to install a grate plate 54 on the upper portion of the water collecting passage 52.

상기 차량위치감지센서(30)를 컨트롤러(40)에 연결하고, 상기 컨트롤러(40)를 펌프(20)와 밸브(14) 각각에 연결하며, 상기 컨트롤러(40)를 컨트롤하우스(45) 내부에 설치하여 구성한다.The vehicle position detecting sensor 30 is connected to the controller 40, the controller 40 is connected to each of the pump 20 and the valve 14, and the controller 40 is connected to the inside of the control house 45. Install and configure.

본 발명 기술구성의 미설명부호 100은 내구차량, 102은 프론트 쇽업저버, 104은 리어 쇽업저버를 나타낸 것이다.Reference numeral 100 in the technical configuration of the present invention denotes a durable vehicle, 102 denotes a front shock absorber, and 104 denotes a rear shock absorber.

따라서 본 발명은, 내구차량(100)이 분사노즐(12)의 위치에 다다르면 차량위치 감센서(30)가 내구차량(100)을 감지하고, 내구차량(200)의 위치를 감지한 데이타 값이 컨트롤러(40)에 전해지며, 상기 컨트롤러(40)가 펌프(20)를 작동시켜 저수조(50)의 물을 끌어올리고, 밸브(14)가 개방되어 본사노즐(12)을 통하여 험로에서의 과도한 운동으로 과열된 프론트, 리어 쇽업저버(102)(104)에 물을 분사하게 되는 것이다.Therefore, in the present invention, when the durable vehicle 100 reaches the position of the injection nozzle 12, the vehicle position sensor 30 detects the durable vehicle 100, the data value of detecting the position of the durable vehicle 200 It is transmitted to the controller 40, the controller 40 operates the pump 20 to draw up the water in the reservoir 50, the valve 14 is opened to the excessive movement in the humrough through the head office nozzle 12 Water is sprayed on the front and rear shock absorbers 102 and 104 that are overheated.

상기 프론트, 리어 쇽업저버(102)(104)를 냉각시킨 물은 다시 시험로(200) 받가에 모아져 집수로(52)를 통하여 저수조(50)로 돌아와 다시 활용되고, 흡수구(22)의 여과망은 오염물이 펌프(20)로 유입되지 않도록 한다.The water cooled by the front and rear shock absorbers (102, 104) is collected in the test furnace (200) receiving back and returned to the water tank (50) through the water collecting passage (52), and the filter net of the absorber (22) is used again. Prevent contaminants from entering the pump 20.

험로에서 내구차량(100)이 30~40Kph의 속도로 주행하기 때문에 하나의 분사노즐로 분사하여서는 냉각시간이 충분하지 않아 바닥에 다수의 분사노즐(12)을 설치하며, 내구차량(100)의 위치가 감지되면 내구차량(100)과 위치가 가까운 분사노즐(12)로부터 물이 분사되기 시작하여 멀리 떨어져 있는 분사노즐(12)로 순차적으로 냉각수를 분사하도록 컨트롤러(40)가 밸브(14)를 제어하며, 한 개의 분사노즐(12)당 분사시간은 고정되어 있어 분사노즐(12)당 자체의 1회 분사량을 분사하고 나서 자동으로 분사를 멈추게 함으로써 불필요한 냉각수의 분사를 최소화하는 것이다.Since the durable vehicle 100 travels at a speed of 30 to 40 Kph in the rough road, the cooling time is not sufficient by spraying with one spray nozzle, so that a plurality of spray nozzles 12 are installed on the floor, and the position of the durable vehicle 100 is Is detected, the controller 40 controls the valve 14 to sequentially spray cooling water from the injection nozzle 12 close to the durable vehicle 100 to the injection nozzle 12 far away. And, the injection time per one injection nozzle 12 is fixed to minimize the injection of unnecessary cooling water by stopping the injection automatically after the injection of its own single injection amount per injection nozzle 12.

이상과 같이 본 발명은, 냉각수탱크와 냉각수 분사용펌프 및 배터리를 내구차량에 탑재하지 않도록 되므로, 종래에 비하여 내구차량의 중량에 관함 시험조건을 정확히 관리할 수 있고, 냉각수를 재충진시킬 필요가 없으므로 시험시간을 절약할 수 있으며, 또한 자동으로 냉각수를 정확히 분사하여 확실한 냉각효과를 얻을 수 있음은 물론 사용이 편리한 이점을 갖는다.As described above, the present invention does not mount the cooling water tank, the cooling water injection pump, and the battery in the endurance vehicle, and thus it is possible to accurately manage the test conditions regarding the weight of the endurance vehicle, and to refill the cooling water. Therefore, the test time can be saved, and the cooling water can be automatically and accurately sprayed to obtain a certain cooling effect, as well as the convenience of use.
