본 발명은 자동차 공기 현가장치의 냉각구조에 관한 것으로, 특히 대형트럭 및 버스의 엔진에 설치되는 공기압축기에 배출되는 고열의 압축공기를 공냉식으로 조기 냉각시키며, 엔진오일 및 응축수가 배출되도록 한 자동차 공기 현가장치의 냉각구조에 관한 것이다.The present invention relates to a cooling structure of an automobile air suspension system, and in particular, to precool the high-temperature compressed air discharged to an air compressor installed in an engine of a large truck and a bus by air cooling, and to discharge engine oil and condensed water. It relates to a cooling structure of the suspension system.

종래에는 첨부 도면 제1도에 도시된 바와 같이, 엔진내의 공기압축기(a)에서 배출되는 고열의 압축공기는 파이프(b)를 통해 공기건조기(c)로 배출되어 공기건조기(c)의 내부에 있는 데시칸트 흡수제에 공기의 수분이 흡수되어 흡수된 수분은 배수밸브(d)로 배출되고 건조된 공기는 공기건조기(c)에 파이프(b)로 연결된 공기정화탱크(e)를 통해 공기탱크(f)에 저장된다. 이때 압력조정기(g)는 공기탱크(f)의 압력을 일정하게 유지시키며, 일정 압력으로 저장된 공기는 공압으로 주행중인 차량의 바퀴에 제동을 거는 중요한 역할을 하였다.Conventionally, as shown in Figure 1 of the accompanying drawings, the high-temperature compressed air discharged from the air compressor (a) in the engine is discharged to the air dryer (c) through the pipe (b) to the interior of the air dryer (c) Moisture absorbed by the moisture in the desiccant absorbent is discharged to the drain valve (d) and the dried air through the air purification tank (e) connected to the air dryer (c) by a pipe (b) ( f). At this time, the pressure regulator (g) maintains a constant pressure in the air tank (f), the air stored at a constant pressure played an important role to brake the wheel of the vehicle running at pneumatic pressure.

그러나 공기압축기(a)에서 고열의 압축공기가 파이프(b)를 통해 배출될 때 미소한 엔진 오일이 공기건조기(c)에 흡입되어 공기건조기(c)의 데시칸트 흡수제의 수분 흡수 능력을 저하시키고 흡입된 압축공기의 고열로 공기건조기(c)의 내부가 손상되기도 쉬워 자동차의 제동력에도 영향을 주어 브레이크 불량 및 기능저하를 일으켰다.However, when the high-temperature compressed air is discharged through the pipe (b) in the air compressor (a), the minute engine oil is sucked into the air dryer (c) to lower the water absorption capacity of the desiccant absorbent of the air dryer (c). The inside of the air dryer (c) is also easily damaged by the high temperature of the compressed air sucked in, which also affects the braking power of the car, causing brake failure and deterioration.

이와 같은 종래의 문제점을 감안하여 안출한 것으로, 본 발명은 공기압축기와 파이프로 연결된 공기건조기의 사이에 공기냉각기가 파이프로 연결되도록 설치하고 공기압축기에서 배출되는 고열의 압축공기가 냉각되도록 공기압축기와 공기냉각기에 연결된 파이프의 둘레에 냉각핀을 설치한 것으로 공기건조기가 고열의 압축공기에 의해 내구수명이 단축되던 것을 연장시키며 공기건조기에 흡입되어 들어오던 엔진 오물을 중간에 설치된 공기냉각기에서 배출되도록 하여 데시칸트 흡수제의 수명을 연장하며 공기압 브레이크의 제동력을 향상시키는데 그 목적이 있다.The present invention has been made in view of the above-described problems, the present invention is installed between the air compressor and the air dryer connected by a pipe air cooler is connected to the pipe and the air compressor to cool the high-temperature compressed air discharged from the air compressor Cooling fins are installed around the pipe connected to the air cooler, which extends the service life of the compressed air by high temperature compressed air and discharges the engine dirt that was sucked into the air dryer from the air cooler installed in the middle. The purpose is to extend the life of desiccant absorbents and to improve the braking force of pneumatic brakes.
