본 발명은 도 1 및 도 2에 도시한 바와 같이, 트럭 등의 차량에서 에어컨 컴프레서(1)를 장착시에 공간활용 및 엔진관련 부품들과의 간섭을 피하기 위한 것으로서, 엔진(E)의 크랭크 샤프트 풀리(3)에 브이 벨트(4")로 연결되어 엔진(E)의 구동과 동시에 구동하는 보기 구동기구인 컴프레서, 워터 펌프, 오일 펌프 및 파워 스티어링 오일 펌프 등의 샤프트인 예를들어, 파워 스티어링 오일 펌프(11)의 샤프트(11')를 연장하여 샤프트(11')에 일단을 결합하고, 타단을 컴프레서 풀리(12)에 볼트(13)로 고정하는 커플링(10)을 형성한 것이다.1 and 2, the crankshaft of the engine (E) to avoid space utilization and interference with engine-related components when mounting the air conditioner compressor (1) in a vehicle such as a truck For example, the power steering oil is a shaft of a compressor, a water pump, an oil pump, and a power steering oil pump, which are bogie drive mechanisms connected to the pulley 3 by a V-belt 4 "and simultaneously drive the engine E. Coupling 10 is formed by extending shaft 11 'of pump 11 to couple one end to shaft 11' and fixing the other end to compressor pulley 12 with bolt 13.

상기 커플링(10)의 일단은 보스형상으로 형성하고 파워 스티어링 오일 펌프(11)의 샤프트(11')는 스플라인축형상으로 형성하여, 파워 스티어링 오일 펌프(11)의 샤프트(11')에 커플링(10)의 일단을 끼워서 조립함을 통해 파워 스티어링 오일 펌프(11)의 구동력이 커플링(10)에 전달되게 하는 것이다. 상기 파워 스티어링 오일 펌프(11)의 샤프트(11')는 엔진(E)의 측방향에 위치되게 되어, 이와 연결되는 컴프레서(1)는 엔진(E)의 측부 또는 후미에 위치되게 되므로서, 엔진관련 부품들과의 간섭을 피하게 되는 것이다.One end of the coupling 10 is formed in a boss shape, and the shaft 11 'of the power steering oil pump 11 is formed in a spline shaft shape to couple to the shaft 11' of the power steering oil pump 11. By assembling one end of the ring 10, the driving force of the power steering oil pump 11 is transmitted to the coupling 10. The shaft 11 ′ of the power steering oil pump 11 is located in the lateral direction of the engine E, so that the compressor 1 connected thereto is located at the side or the rear of the engine E, thereby providing engine-related Interference with components is avoided.

그리고 상기 커플링(10)은 일체로 형성하는 것이며, 설치위치를 조정할 수 있도록 하기 위하여, 파워 스티어링 오일 펌프(11)의 샤프트(11')에 조립되는 연결부(14)와, 상기 연결부(14)에 볼트(13)로 고정되며 컴프레서(1) 설치위치를 가변시킬 수 있도록 하기 위한 길이 조정부(15)와, 상기 길이 조정부(15)에 볼트(13)로 고정되며 컴프레서 풀리(12)에 볼트(13)로 고정되는 몸체(16)로 분리하여 고정할 수 있는 것이다. 또한, 상기한 길이 조정부(15)를 사용하지 않고 연결부(14)와 몸체(16)를 고정한 후 연결부(14)를 파워 스티어링 오일 펌프(11)의 샤프트(11')에 끼우고 몸체(16)를 컴프레서 풀리(12)에 고정하여 사용할 수 있는 것이다.And the coupling 10 is formed integrally, in order to be able to adjust the installation position, the connecting portion 14 assembled to the shaft 11 'of the power steering oil pump 11, and the connecting portion 14 Is fixed to the bolt 13 to the length adjusting unit 15 for varying the installation position of the compressor (1), the length adjusting unit 15 is fixed to the bolt (13) and bolts to the compressor pulley (12) 13) to be fixed by separating the body 16 is fixed. In addition, after fixing the connecting portion 14 and the body 16 without using the length adjusting portion 15 described above, the connecting portion 14 is inserted into the shaft 11 'of the power steering oil pump 11 and the body 16 is fixed. Can be fixed to the compressor pulley 12 and used.

이상과 같이 커플링(10)을 이용하여 파워 스티어링 오일 펌프(11)의 샤프트(11')에 컴프레서 풀리(12)를 연결하게 되면, 엔진(E)의 구동과 동시에 크랭크 샤프트 풀리(3)와 브이 벨트(4")로 연결된 파워 스티어링 오일 펌프(11)의 풀리(11")가 브이 벨트(4")에 의해 회전하게 되어 파워 스티어링 오일 펌프(11)의 샤프트(11')가 회전하게 되고, 파워 스티어링 오일 펌프(11)의 샤프트(11')가 회전됨과 동시에 커플링(10)이 회전하게 되며, 커플링(10)의 회전과 동시에 컴프레서 풀리(12)가 회전하게 되는 것이다.As described above, when the compressor pulley 12 is connected to the shaft 11 'of the power steering oil pump 11 by using the coupling 10, the crankshaft pulley 3 and the engine are driven at the same time. The pulley 11 "of the power steering oil pump 11 connected by the V belt 4" is rotated by the V belt 4 "so that the shaft 11 'of the power steering oil pump 11 is rotated. As the shaft 11 'of the power steering oil pump 11 rotates, the coupling 10 rotates, and the compressor pulley 12 rotates simultaneously with the rotation of the coupling 10.

한편, 설치위치를 조정할 필요가 있는 경우에는, 연결부(14)에 길이 조정부(15)를 고정하고, 길이 조정부(15)에 몸체(16)를 고정하므로서 길이가 조정되는 것이고, 이상태에서 커플링(10)의 일단을 파워 스티어링 오일펌프(11)의 샤프트(11')에 끼우고 타단을 컴프레서 풀리(12)에 고정하면 되는 것이다.On the other hand, when it is necessary to adjust the installation position, the length is adjusted by fixing the length adjusting part 15 to the connecting portion 14 and fixing the body 16 to the length adjusting part 15, and in this state the coupling ( One end of 10) may be inserted into the shaft 11 'of the power steering oil pump 11 and the other end may be fixed to the compressor pulley 12.

이상태에서 사용자가 도시하지 않은 에어컨 스위치를 온(ON)시키게 되면, 에어컨 컴프레서 내부에 장착된 클러치(미도시)에 의해 컴프레서 풀리(12)의 회전력이 내부장치와 연결되게 되어 결과적으로 에어컨 컴프레서가 작동되게 되는 것이다.When the user turns on an air conditioner switch (not shown) in this state, the rotational force of the compressor pulley 12 is connected to the internal device by a clutch (not shown) mounted inside the air conditioner compressor, and as a result, the air conditioner compressor operates. It will be.

이상과 같이 본 발명은 컴프레서 풀리가 커플링에 의하여 파워 스티어링 오일 펌프의 샤프트에 간단하게 고정되게 되므로서, 컴프레서 설치시 브이 벨트를 사용하지 않으면서 적정하게 설치위치를 가변시키면서 설치할 수 있는 효과가 있는 것이다.As described above, the present invention has the effect that the compressor pulley is easily fixed to the shaft of the power steering oil pump by the coupling, so that it can be installed while varying the installation position appropriately without using the V-belt when installing the compressor. will be.

또한, 크랭크 샤프트 풀리를 기준으로 수직방향으로 동일평면상에 컴프레서를 설치하지 않아도 되어 엔진관련 부품들과의 간섭이 발생하지 않아 결과적으로 장착성이나 조립성이 향상되는 것이다.In addition, since the compressor does not need to be installed on the same plane in the vertical direction with respect to the crankshaft pulley, interference with engine-related parts does not occur, and as a result, mounting and assembly properties are improved.
