본 고안은 에어 브레이크 시스템에 관한 것으로 솔레노이드 밸브 및 브레이크 챔버로 구성된 차량에 있어서의 주차 브레이크 패드 보호를 위한 주차 브레이크 안전장치에 관한 것이다.The present invention relates to an air brake system and to a parking brake safety device for protecting a parking brake pad in a vehicle composed of a solenoid valve and a brake chamber.
종래의 에어 브레이크 시스테은 첨부도면 제2도에 도시된 바와 같이 주차 브레이크 패드(11)와 상기 주차 브레이크 패드(11)를 작동시키는 브레이크 챔버(12)로 이루어진 작동부와;The conventional air brake cyste includes an operating unit including a parking brake pad 11 and a brake chamber 12 for operating the parking brake pad 11, as shown in FIG.
상기 작동부를 조절하기 위한 조절부로서 에어탱크(14)와 솔레노이드 밸브(13)와 주차용 of-off 스위치(15)와 주차시 중립위치 스위치(16)로 구성되어 있다.As an adjusting unit for adjusting the operation unit, the air tank 14, the solenoid valve 13, the parking of-off switch 15 and the neutral position switch 16 when parking.
이와 같은 종래의 브레이크 시스템에 있어서 작동상태는 주차 브레이크 해제시 먼저 주차용 of-off 스위치(15)를 온(on)위치에 두면 솔레노이드 밸브(13)는 포트를 열어주도록 하므로서 에어탱크(14)내의 에어가 브래이크 챔버(12)에 작용하게 된다.In the conventional brake system, the operation state is that when the parking brake is released first, the parking of-off switch 15 is placed in the on position so that the solenoid valve 13 opens the port and the air tank 14 is opened. Air acts on the brake chamber 12.
따라서 브레이크 챔버(12)내의 에어실린더를 작동하여 브레이크 패드(11)가 해제되게 되는 것이다.Therefore, the brake pad 11 is released by operating the air cylinder in the brake chamber 12.
그런데 상기 솔레노이드 밸브(13)의 포트 입구에 이물질이 끼어 막혀 있을 경우 주차용 of-off 스위치(15)를 온위치에 작동하더라도 브레이크 챔버(12)내의 에어가 통하지 못하므로 브레이크 패드(11)는 해제되지 않게 된다.However, when foreign matter is blocked in the port inlet of the solenoid valve 13, even if the parking of-off switch 15 is operated in the on position, air in the brake chamber 12 does not pass, so the brake pad 11 is released. Will not be.
그러나 이를 감지하지 못한 운전자는 브레이크 패드(11)가 해제되지 않은 상태에서 그대로 차량을 주행하게 되므로서 해제되지 못한 브레이크 패드(11)는 급격한 마모와 과열이 발생되어 차량 수명 단축 및 안전사고의 우려가 있었다.However, the driver who does not detect this is driving the vehicle as it is without the brake pad 11 is released, so the brake pad 11 that is not released suddenly wears out and overheats, resulting in a shortened vehicle life and a safety accident. there was.
이와 같은 문제점을 해소하기 위하여 안출된 본 고안에서는 에어용 브레이크 시스템에 있어서 주차용 솔레노이드 밸브가 이물질에 의해 막혔을 때 운전자가 즉시 감지할 수 있도록 하며, 차량 주행을 방지하도록 하는 주차 브레이크용 안전장치를 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention provides a parking brake safety device that enables the driver to immediately detect when the parking solenoid valve is blocked by foreign substances in the air brake system and prevents the vehicle from running. Its purpose is to.
상기의 목적을 달성하기 위하여 본 고안에서는 주차용 솔레노이드 밸브의 입구 포트가 이물질에 의하여 막혀 브레이크 챔버내의 에어가 통하지 못하여 브레이크 패드가 해제되지 않을 경우 이를 쉽게 감지할 수 있도록 압력감지장치를 부설하여 운전실에는 경고등을 설치하고, 상기 압력감지장치에 의해 작동되는 주차시 중립위치 스위치에 의하여 차량의 주행방지기능을 갖도록 함을 특징으로 한다.In order to achieve the above object, in the present invention, an inlet port of a parking solenoid valve is blocked by a foreign material, and thus a pressure sensing device is installed in the cab to easily detect when the brake pad is not released because the air in the brake chamber cannot pass. A warning light is installed, and the vehicle is prevented from running by the neutral position switch when operated by the pressure sensing device.
이하 첨부된 도면에 의거하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 에어시스템 주차 브레이크 장치용 회로도로서 작동부와 상기 작동부의 압력을 조절하는 조절부와 상기 작동부의 압력을 감지하는 압력감지장치부로 구성되어 있다.1 is a circuit diagram for an air system parking brake apparatus of the present invention, and includes an operating part, an adjusting part for adjusting the pressure of the operating part, and a pressure sensing device part for detecting the pressure of the operating part.
작동부는 주차용 브레이크 패드(111)와 상기 주차용 브레이크 패드(111)를 작동시키도록 에어실린더가 내장된 브레이크 챔버(112)를 구성요소로 한다.The operating unit includes a parking brake pad 111 and a brake chamber 112 in which an air cylinder is built to operate the parking brake pad 111 as a component.
조절부는 상기 작동부의 작용을 조절하기 위하여 압축공기가 충전된 에어탱크(114)와 상기 에어탱크(114)의 압축공기를 제어하는 솔레노이드 밸브(113)와 상기 솔레노이드 밸브(113)를 작동시키는 주차용 on-off 스위치(115)와 주차시 중립위치 스위치(116)를 구성요소로 한다.The control unit is a parking tank for operating the solenoid valve 113 and the solenoid valve 113 for controlling the compressed air of the air tank 114 and the compressed air filled with compressed air in order to adjust the action of the operation unit The on-off switch 115 and the neutral position switch 116 when parking are components.
또한 압력감지부는 상기 작동부의 브레이크 챔버(112)의 압력을 감지하는 압력감지스위치(120)와 상기 압력감지스위치(120)에 의하여 작동되는 경고등(121)을 부설함으로서 브레이크 챔버(112)내의 압력 이상 유무를 판별하며 또한 주차시 중립위치 스위치(116)에도 연결하여 상호 작동이 이루어지도록 한다.In addition, the pressure detection unit by installing a pressure detection switch 120 for detecting the pressure of the brake chamber 112 of the operating unit and the warning light 121 operated by the pressure detection switch 120 or more in the pressure in the brake chamber 112. The presence of the vehicle is also connected to the neutral position switch 116 during parking so that the mutual operation is performed.
이와 같이 구성된 본 고안의 작용 및 효과를 살펴본다.It looks at the operation and effects of the present invention configured as described above.
차량 주행을 위하여 주차브레이크의 해제시에는 먼저 주차용 on-off 스위치(115)를 on 위치로 작동한다.When the parking brake is released for driving the vehicle, the on-off switch 115 for parking is first operated in the on position.
상기 주차용 on-off 스위치(115)에 의하여 신호가 솔레노이드 밸브(113)에 인가되면 상기 솔레노이드 밸브(113)의 입구 포트가 열리게 되며 에어탱크(114)에 저장된 압축공기가 이동하여 브레이크 챔버(112)를 작동시키게 된다.When the signal is applied to the solenoid valve 113 by the parking on-off switch 115, the inlet port of the solenoid valve 113 is opened and the compressed air stored in the air tank 114 moves to the brake chamber 112. ) Will be activated.
따라서 브레이크 챔버(112)내의 에어실린더가 작동하여 주차용 브레이크 패드(111)를 해제하도록 한다.Therefore, the air cylinder in the brake chamber 112 is operated to release the parking brake pad 111.
그러나 솔레노이드 밸브(113)가 각종 이물질에 의하여 입구 포트가 막혀있을 경우 주차용 on-off 스위치(115)를 작동하여도 에어탱크(114)의 압축공기가 진입하지 못하므로 브레이크 챔버(112)에는 압력이 작용하지 않게 된다.However, when the solenoid valve 113 is blocked by various foreign substances, even if the on-off switch 115 for parking does not operate, the compressed air of the air tank 114 does not enter the brake chamber 112. This will not work.
이때 브레이크 챔버(112)와 연결된 압력감지스위치(120)는 브레이크 챔버(112)내의 압력이 저압임을 감지하여 운전실내에 설치된 경고등(121)을 점등하도록 한다.At this time, the pressure sensing switch 120 connected to the brake chamber 112 detects that the pressure in the brake chamber 112 is low, so that the warning lamp 121 installed in the cab is turned on.
또한 주차시 중립위치스위치(116)를 작동하여 차량의 주행이 방지되도록 하여 운전자로 하여금 주차 브레이크용 에어시스템의 이상유무를 쉽게 감지하도록 한다.In addition, the neutral position switch 116 is operated during parking so that the vehicle is prevented from traveling so that the driver can easily detect an abnormality of the parking brake air system.
따라서 주차용 브레이크 패드(111)의 해제가 되지 않은 상태에서는 절대로 주행이 되지 않도록 하므로서 브레이크 패드(111)의 마모를 방지할 수 있도록 하는 것이다.Therefore, it is possible to prevent abrasion of the brake pad 111 while never driving in the state where the parking brake pad 111 is not released.
