FIELD OF THE INVENTIONThe present invention relates generally to an apparatus for a radiator cooling fan hub. More specifically, the present invention is a direct drive radiator cooling fan hub to eliminate engine overheating that is caused due to a failing or inefficient electronic thermal clutch fan.
BACKGROUND OF THE INVENTIONOne of the most common problems associated with a failing or inefficient electronic thermal clutch fan is an overheating engine. The electronic thermal clutch fan is responsible for controlling the operation of the radiator cooling fans of a vehicle. For examples, A bad or failing electronic thermal clutch fan may not engage properly thus disabling the radiator cooling fan operation with in a vehicle causing it to overheat. When a vehicle is towing a heavy load under extreme cold or hot weather conditions, the electronic thermal clutch fan may not operate up to the maximum efficiency for cooling the engine properly. The efficiency of the electronic thermal clutch fan is normally tested at the standard room temperature. When a vehicle is towing a heavy load in a higher elevation, the electronic thermal clutch fan may not operate up to the maximum efficiency. The efficiency of the electronic thermal clutch fan is normally tested at the sea level, wherein the elevation is not a factor and tested under non-extreme towing conditions. As a result of those examples, the engine may result in overheating and lead to more serious mechanical issues as the operator of the vehicle may be unaware of the failing or inefficient electronic thermal clutch. Furthermore, it also affects the air conditioning, transmission cooling, the engine oil temperature, and radiator temperature.
It is therefore an object of the present invention to introduce an apparatus for a direct drive radiator cooling fan hub that replaces the existing electronic thermal clutch fan. More specifically, the present invention provides a direct drive and non-electronic hub between a fan pully of the engine and a radiator cooling fan assembly of the vehicle thus eliminating potential problems such as failing electronic parts, failing mechanically coupled parts, and inefficiency that are currently present within the electronic thermal clutch fan and the control module. As a result, the present invention is able to eliminate engine overheating in relation to a bad or failing electronic thermal clutch fan, higher elevations, extreme hot or cold weather conditions, racing, or towing. The present invention also optimizes the efficiency of the air conditioning process, transmission cooling process, oil temperature, and the radiator temperature thus resulting less thermal stress on the engine.
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
The present invention is a direct drive radiator cooling fan hub that replaces functionality of the electronic thermal clutch fan of a vehicle. More specifically, the electronic thermal clutch fan is designed to perform under normal conditions such as the sea level, the standard room temperature, and daily transportation. However, one of the common problem with vehicles that utilize the electronic thermal clutch fan is an overheating engine due extreme weather conditions, higher elevations, or higher/extreme towing capacities as the electronic thermal clutch fan is either a failing part or not able to perform up to maximum efficiency. The present invention is able to overcome the engine overheating problem as the present invention provides a direct drive and non-electronic hub in between a fan pully of the engine and a radiator cooling fan assembly of the vehicle. As a result, the present invention is continuously able to power the radiator cooling fan assembly without factoring outside elements such as elevation and temperature. In reference to
The cylindrical body 1, which provides the necessary surface area to mount a radiator cooling fan of the vehicle, comprises a first base wall 2, a second base wall 3, and a lateral wall 4 as shown in
The at least one flange 5 that centrally positions the radiator cooling fan is concentrically positioned along the rotational axis 11 and terminally connected to the cylindrical body 1 as shown in
The plurality of fan blade attachments 6 provides a mean to secure the radiator fan to the cylindrical body 1. In reference to
The fan pully attachment nut 7 attaches the present invention to the fan pully. In reference to
In order to withstand applied torque and to reduce the weight, the present invention is preferably made from 6061 aluminum. However, the present invention is not limited 6061 aluminum and can be made from any other type of material high strength and lightweight materials to minimize wear and tear on the fan pully and to allow longevity of the bearing. Since the present invention operates under any environmental conditions and does not require a computer or an electronic thermostat to operate, the present invention immediately and continuously implements the cooling process for the engine. As a result, the present invention can be beneficial for government tactical vehicles that relies on engine fan cooling to keep the interior and engine cool, for race trucks with the higher engine capacity, for commercial trucks that haul heavy loads.
Since the present invention does not require additional component during the installation and provide a direct attachment to the fan pully, the present invention facilitate an easy installation process. in reference to the installation method, first, loosen all shroud fan bolts and unplug the fan shroud on bottom of the radiator. Then, loosen the fan hub nut and spin off the fan hub. Then, Lift the radiator cooling fan and the electronic thermal clutch fan out of engine compartment to remove the bolt fasteners that connect the radiator cooling fan to the electronic thermal clutch fan. The radiator cooling fan is then positioned flush with the at least one flange 5 and reattached to present invention through the plurality of fan blade attachments 6. The present invention is then reinstalled between the fan shroud and the radiator as the fan pully attachment nut 7 is threaded onto the fan pully with reverse rotation (or forward rotation depending on the engine design). As the final step, the fan shroud is then reinstalled thus covering the present invention and the radiator cooling fan.
In a preferred embodiment of the present invention, the cylindrical body 1 is 7 inches in diameter and 2 inches in thickness. The diameter for the each of the plurality of fan blade attachments 6 is 5/16 inches, and the inner diameter of the fan pully attachment nut 7 is 19/16 inches. The weight is about 3.5 pounds. The aforementioned dimensions of the preferred embodiment are specifically adopted for 2003-2017 Dodge vehicles with a 6.7 Cummins Engine, 2003-2007 Dodge vehicles with a 5.9 Cummins Engine, and All vehicles with 6.7/5.9 Cummins from 2003 to 2017.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
