The fan blade coupling assembly is a key component in the engine cooling system of Ford Pickup RANGER and Mazda BT50 3.2L models. It is mainly installed between the fan and the fan pulley to achieve automatic control of the fan speed, ensuring that the engine can maintain normal operating temperature under various working conditions.
Working principle
Temperature sensing mechanism: The front of the coupler is equipped with a bimetallic spring that can sense the temperature of the coolant flowing through the radiator. When the car is cold, the valve controlled by the bimetallic spring closes; When the engine temperature rises, the hot coolant deforms the bimetallic wire and opens the valve.
Principle of silicone oil transmission: After the valve is opened, the silicone oil in the coupling will flow between the driving plate and the driven plate, using the viscosity of the silicone oil to transmit power, so that the fan speed increases with the engine temperature, enhancing the heat dissipation effect; After the temperature drops, the valve closes and the silicone oil flows back to the storage chamber under centrifugal force, causing the fan speed to decrease.
Product advantages
Precise adaptation: Specially designed for the Ford RANGER and Mazda BT50 3.2L models, it perfectly matches the vehicle's engine cooling system in terms of size, mounting holes, connection methods, etc., ensuring easy installation without the need for additional modifications or adjustments.
Efficient heat dissipation: It can adjust the fan speed in real-time and accurately according to the actual temperature of the engine. In high load operation or high temperature environment of the engine, it can quickly increase the fan speed, increase the heat dissipation air volume, effectively prevent engine overheating, and ensure stable engine performance and service life.
Shock absorption and noise reduction: During the transmission of power, it can effectively buffer the vibration and impact force generated by the fan rotation, reduce the transmission of vibration to the body and other components, lower the noise inside the car, and improve driving comfort.
Energy saving and consumption reducing: avoids unnecessary high-speed operation of the fan, reduces engine power loss, thereby reducing fuel consumption and achieving energy saving and emission reduction.
Quality Assurance
High quality materials: The shell and key transmission components are made of high-strength and wear-resistant metal materials to ensure that they can withstand the stress of fan rotation and various complex working conditions during long-term use; The internal silicone oil is selected from high-purity and stable performance products, which have good thermal stability and viscosity retention.
Strict testing: During the production process, strict quality control standards are followed, and multiple testing processes are carried out, including appearance inspection, dimensional accuracy measurement, performance testing, etc., to ensure that each fan blade coupling assembly meets or exceeds the original factory requirements.
