Weichai WP 12/13 Heavy Duty Truck Parts New 612600062253 Fan Clutch for Engine Essential 612600062253 Component

When the engine load increases and the coolant temperature increases, the temperature of the air flow through the radiator core also increases. The high temperature air is blown on the bimetal temperature sensor, which causes the bimetal plate to be heated and deformed, and drives the drive pin of the valve plate and the control valve plate to deflect an Angle. When the air temperature exceeds 65 ° C, the oil inlet hole A on the driven plate is opened, and the silicone oil in the oil storage chamber enters the working chamber through this hole. Viscous silicone oil flows into the gap between the driving plate and the driven plate and the driving plate and the clutch housing, and the torque on the driving plate is transmitted to the clutch housing, driving the fan to rotate at high speed, and the clutch is in the engaged state.
