As shown, the water jacket 52 provided in the cylinder block 50 and the cylinder head 51, the radiator 53 and the radiator fan 54 for cooling the coolant heated in the water jacket 52, and the radiator ( 53, the water pump 55 for supplying the coolant cooled back to the cylinder block 50 and the cylinder head 51, and the circulation path of the coolant according to the water temperature between the water jacket 52 and the radiator 53 A thermostat (THERMOSTAT) 56 to be changed is provided.

또한, 상기 라디에이터(53)는 냉각수의 냉각 효율을 향상시키고 물펌프(55)의 흡입측 압력을 대기압 이상으로 유지하도록 하기 위해 라디에이터 캡 및 리저버 탱크를 두고 있다.In addition, the radiator 53 has a radiator cap and a reservoir tank to improve the cooling efficiency of the cooling water and to maintain the suction side pressure of the water pump 55 above atmospheric pressure.

상기한 물펌프(55)는 엔진의 구동력으로 회전하도록 되어 있는 바, 엔진의 크랭크샤프트 풀리와 상기 물펌프의 풀리가 벨트로 연결되어 엔진이 구동하여 크랭크샤프트 풀리가 회전하면 상기 물펌프가 회전하도록 되어 있다.The water pump 55 is to be rotated by the driving force of the engine bar, the crankshaft pulley of the engine and the pulley of the water pump is connected to the belt so that the engine is driven to rotate the water pump when the crankshaft pulley rotates.

이하, 첨부된 도면을 참조하여 본 발명의 실시 예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 보조 물펌프 구동장치를 도시한 것으로서, 물펌프(1)를 구동하는 물펌프 풀리(2)와 동심축으로 회전하는 물펌프 마찰차(3)와, 상기 물펌프 마찰차(3)의 회전력을 전달받아 보조 물펌프(4)를 구동하는 보조 물펌프 마찰차(5)와, 상기 물펌프 마찰차(3)의 회전력이 보조 물펌프 마찰차(5)로 전달되는 것을 단속하는 동력전달수단과, 서모스탯(6)이 개방되는 것을 감지하는 유속센서(7)와, 상기 유속센서(7)의 신호에 따라 상기 동력전달수단을 제어하는 ECU(8)로 구성된다.Figure 2 shows an auxiliary water pump driving apparatus according to the present invention, a water pump friction difference (3) that rotates concentrically with the water pump pulley (2) for driving the water pump (1), and the water pump friction The auxiliary water pump friction wheel 5 for driving the auxiliary water pump 4 by receiving the rotational force of the vehicle 3 and the rotational force of the water pump friction wheel 3 are transmitted to the auxiliary water pump friction wheel 5. A power transmission means for regulating the power supply, a flow rate sensor 7 for detecting that the thermostat 6 is opened, and an ECU 8 for controlling the power transmission means in accordance with a signal of the flow rate sensor 7. .

여기서, 상기 동력전달수단은 물펌프 마찰차(3) 및 보조 물펌프 마찰차(5)와 접촉 또는 이격되는 중간 마찰차(9)와, 상기 ECU(8)의 제어신호를 입력받아 상기 중간 마찰차(9)가 상기 물펌프 마찰차(3) 및 보조 물펌프 마찰차(5)와 접촉되도록 하는 액츄에이터(10)로 구성된다.Here, the power transmission means is an intermediate friction difference (9) in contact with or spaced apart from the water pump friction difference (3) and the auxiliary water pump friction difference (5), and receives the control signal of the ECU (8) the intermediate friction The vehicle 9 consists of an actuator 10 which is brought into contact with the water pump friction difference 3 and the auxiliary water pump friction difference 5.

상기한 바와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

엔진이 가동되면 크랭크샤프트 풀리가 회전하고 물펌프 풀리(2)가 회전하면서 물펌프(1)가 구동된다.When the engine is running, the crankshaft pulley rotates and the water pump pulley 2 rotates to drive the water pump 1.

엔진이 초기 시동 시에는 엔진을 회전하는 냉각수의 온도가 높지 않기 때문에 서모스탯(6)은 닫힌 상태를 유지하고, 냉각수는 물재킷(11) 내에서 순환하면서 엔진의 온도 상승이 원활하게 이루어지도록 한다.Since the temperature of the coolant rotating the engine is not high at the initial start of the engine, the thermostat 6 is kept closed, and the coolant is circulated in the water jacket 11 to smoothly increase the temperature of the engine. .

엔진이 정상적으로 가동되어 상기 엔진의 물재킷(11)을 순환하는 냉각수의 온도가 상승하면, 서모스탯(6)이 열리면서 물재킷(11)의 냉각수가 라디에이터로 유입된다.When the engine operates normally and the temperature of the cooling water circulating in the water jacket 11 of the engine rises, the thermostat 6 opens and the cooling water of the water jacket 11 flows into the radiator.

이때, 상기 서모스탯(6)이 열리면서 냉각수가 라디에이터 쪽으로 흐르면 ECU(8)는 유속센서(7)를 통해 이를 감지하고 액츄에이터(10)를 구동시키는 바, 상기 액츄에이터(10)는 중간 마찰차(9)를 이동시켜 상기 중간 마찰차(9)와 물펌프 마찰차(3) 및 보조 물펌프 마찰차(5)가 접촉되도록 한다.At this time, when the thermostat 6 is opened and the coolant flows toward the radiator, the ECU 8 senses this through the flow rate sensor 7 and drives the actuator 10, wherein the actuator 10 has an intermediate friction difference 9. The intermediate friction wheel 9 and the water pump friction wheel 3 and the auxiliary water pump friction wheel 5 are brought into contact with each other.

즉, 상기와 같이 중간 마찰차(9)와 물펌프 마찰차(3) 및 보조 물펌프 마찰차(5)가 접촉되면, 상기 물펌프 마찰차(3)의 회전력이 중간 마찰차(9)를 통해 보조물펌프 마찰차(5)로 전달되어 상기 보조 물펌프 마찰차(5)가 회전하기 때문에 보조물펌프(4)가 구동되게 된다.That is, when the intermediate friction difference 9, the water pump friction difference (3) and the auxiliary water pump friction difference (5), as described above, the rotational force of the water pump friction difference (3) is the intermediate friction difference (9) The auxiliary water pump friction difference (5) is transmitted through the auxiliary water pump friction difference (5) is rotated so that the auxiliary water pump (4) is driven.

상기 보조 물펌프(4)는 물펌프(1)와 함께 라디에이터를 통과하여 냉각된 냉각수를 실린더 블록과 실린더 헤드에 마련된 물재킷(11)으로 공급하여 엔진의 냉각에 사용되도록 한다.The auxiliary water pump 4 supplies the cooling water cooled by passing through the radiator with the water pump 1 to the water jacket 11 provided in the cylinder block and the cylinder head to be used for cooling the engine.

이상과 같이, 본 발명은 엔진의 온도가 저온일 때에는 물펌프만 구동하도록 하여 엔진의 온도 상승이 신속하게 이루어지도록 하고, 엔진의 온도가 고온일 때에는 물펌프와 보조 물펌프가 동시에 구동하도록 하여 라디에이터를 통과한 냉각수가 보다 신속하고 원활하게 물재킷을 순환하도록 하기 때문에 엔진의 냉각 효율이 증대되는 효과가 있다.As described above, the present invention allows only the water pump to be driven when the temperature of the engine is low so that the temperature rise of the engine can be performed quickly, and the water pump and the auxiliary water pump are simultaneously driven when the engine temperature is high. Since the coolant that passes through the water jacket circulates more quickly and smoothly, the cooling efficiency of the engine is increased.
