BIMETAL FAN CLUTCH FOR VEHICLE WITH PIN FOR MEASURING TEMPERATURE OF COOLING WATER

摘要

The present invention relates to a bimetal fan clutch for a vehicle capable of preventing a vehicle engine from overcooling or overheating according to the temperature by directly measuring the temperature of cooling water circulating via the operation of the engine and controlling the speed of the fan of a fan clutch correctly and swiftly according to the temperature of the cooling water. The present invention comprises a spacer (130) contained in a water pump housing (110) and connected to the driving axis (112) of a water pump having an impeller (114) on one surface thereon; a rotor (140) combined with the spacer (130) and connected to a fan (142); a hollow coupling member (150) penetrating the rotor (140) and connected to the spacer (130); a valve (160) combined with a pump (180) connected to one surface of the rotor (140) and controlling the flow of operating oil in an operating oil channel (144); bimetal (170) for controlling the valve (160) according to the temperature; and a pump (180) included at one side of the rotor (140). The present invention includes a pin (190) for measuring a temperature, penetrating from the bimetal (170) to inside the hollow coupling member (150), and to the spacer (130), the driving axis (112) of the water pump and the impeller (114) for circulating cooling water so as to directly receive the temperature of the cooling water and transmitting the temperature to the bimetal (170).
