Advantages of Fan Clutch
Fuel Efficiency: Fan clutches prevent excessive energy consumption, resulting in improved fuel efficiency and reduced operational costs for trucking companies.
Extended Engine Life: Maintaining proper engine temperatures through effective cooling helps extend the lifespan of the engine and its components, reducing maintenance and replacement costs.
Emission Reduction: Proper cooling contributes to cleaner exhaust emissions, aligning with environmental regulations.
Enhanced Performance: Consistent engine temperatures ensure that the engine operates at its designed efficiency, translating to better overall performance and power output.
Types of Fan Clutches
Non-Thermal Fan Clutches
Non-thermal clutches operate solely based on the shaft speed of the water pump. At low and idling speeds, the clutch allows the fan blade to turn at almost a 1:1 ratio. At high speeds, the silicone fluid within in the clutch will lose its ability to transfer the energy from the shaft to the fan clutch body (and therefore, the fan) and the fan is then allowed to almost free-wheel, removing its load from the engine.
Thermal Fan Clutches
The thermal fan clutch operates in response to underhood temperatures. As hot air blows across the radiator, it heats a thermal spring mounted at the front of the clutch. As the spring is heated, it turns and allows valve ports to open within the clutch. Silicone fluid stored inside a reservoir is allowed to pass through these open ports and enter the working area of the clutch. This engages the clutch and drives the fan. Once the engine is cooled down, the thermal spring rotates back and closes the valve ports, disengaging the fan.
Electronic – Viscous EV Fan Clutch Operation
This style of fan clutch operates like a thermal clutch, but the ECM/PCM signal controls the level of engagement of the EV clutch. This engagement process is ultimately controlled through the ECM/PCM by the following input variables: Coolant Temperature, Intake Manifold Temperature, Transmission Oil Temperature, A/C Pressure and Engine Oil Temperature. These variables are manufacturer-specific and fan speed is dictated based on the level of cooling required.
Material of Fan Clutch
High-Quality Carbon Steel Flange (Ball Bearing)
Our uses high-quality carbon steel that is made to withstand high impacts, have high billet density, and have high deformation resistance. Every GMB Ball Bearing is machine press-fitted to the main case using the proper force range.
Precision OEM-Spec Fan Clutch Components
Fan Clutch components are manufactured to match the exact OEM spec materials: high-quality cold rolled steel, aluminum, and carbon steel. Each component is precision measured using state-of-the-art technology to be dimensionally correct, with 99.99% accuracy and strict tolerance limits.
Precision OEM-Spec Test Standard
Fan Clutches are manufactured to match the exact OEM performance that's intended for the vehicle. Each fan clutch is also precision tested using rigorous standards to maintain 99.99% accuracy and strict tolerances.
Proprietary OE Fixed Design
GMB has supplied and worked with OEMs for years and knows most fan clutch issues relate to noise or oil leakage. To prevent oil leakage, GMB Fan Clutches include an oil seal on top of the rotor. GMB also revised the design of the oil seal from a single oil seal to a double oil seal and expanded the return hole to retrieve all oil from the rotor.
Components of Fan Clutch
Thermostat
The thermostat is a temperature-sensitive device that detects changes in engine temperature. It is responsible for engaging or disengaging of the fan clutch. When the engine temperature rises beyond a certain threshold, the thermostat signals the fan clutch to engage and increase the fan's rotational speed.
Bimetallic Spring
The bimetallic spring reacts to changes in temperature by expanding or contracting. This expansion or contraction influences the position of the clutch plate, which in turn controls the engagement of the fan.
Clutch Plate
The clutch plate is connected to the bimetallic spring. When the bimetallic spring expands or contracts, it causes the clutch plate to move. This movement alters the position of the fan blades, adjusting their angle and rotational speed accordingly.
Fluid Filled Chamber
Inside the fan clutch, there is a fluid-filled chamber that regulates the fan's operation. The fluid is sensitive to temperature changes and helps control the movement of the clutch plate.
Use of Fan Clutch
The fan clutch's job is to control when the fan comes on and off. It provides airflow when needed. It also reduces drag on the engine when not needed. This improves power and fuel economy.
The fan disengages when:
The engine is cool
The vehicle's speed forces air through the radiator
The fan engages when:
The engine gets hot
The vehicle is not moving or its speed is slow
Most fan clutches are filled with a silicone-based oil. The oil is held in an internal reservoir when the fan is disengaged.
To engage the fan, internal valves open and allow the fluid to fill the working area of the clutch. This creates friction between the drive plate and the housing, causing the fan to spin.
To disengage the fan, the valves close. The fluid is kept in the reservoir. This reduces the friction and allows the housing and fan to spin independently of the shaft.
