摘要： A hydraulically controlled fan drive system for controlling the cooling of an engine and having a method of engagement includes a housing assembly containing a hydraulic fluid and an engaging circuit. The engaging circuit includes a pitot tube coupled within the housing assembly that receives at least a portion of the hydraulic fluid as the housing assembly rotates to drive a clutch pack (and coupled fan) via static pressure. A fluid controller having binary control adjusts the static pressure within the pitot tube at a given rotational speed, thereby controlling the engagement of the clutch pack to a fully engaged drive (utilizing friction type engagement), a fully disengaged drive, and at least two partially engaged clutch positions (i.e. partially engaged utilizing a wet viscous type clutch engagement). To control static pressure release, the fluid controller may utilize a dual spool system valving arrangement or a parallel fixed orifice binary control.

摘要： A flexible metal disk used to mount the fan to the fan drive. The metal disk is a resilient mounting, and as such reduces vibration levels between the fan and fan drive, thereby preventing damage to various components within the cooling system. The flexible metal disk also functions to self align the fan and the fan drive. The flexible metal disk is also durable, and therefore offers improved creep and deterioration resistance as compared with typical elastomeric mountings. In another preferred embodiment, multiple flexible metal disks may be coupled together and used to mount the fan to the fan drive to provide additional damping as compared with single disk systems.

摘要： A fan drive assembly including a cooling fan (11) and a fluid coupling device (13). The cooling fan includes a fan hub (17), a spider (15), and a plurality of fan blades (19). The coupling device has an output coupling assembly (21) including a body (23) and a cover (25). The body (23) includes preferably only three mounting portions (67), each being disposed immediately adjacent an outer periphery of the body. Each of the mounting portions (67) defines the necessary machining chucking surfaces (73), and a spider mounting surface (75) including a pilot surface (77) engaging the pilot diameter (79) of the spider (15). The body (23) includes cooling fins (61) covering substantially all of the rearward surface (59) of the body not covered by the mounting portions. The fan hub (17) also includes a rearwardly extending air dam portion (81), limiting localized radial air flow. The fan drive is able to improve the radial air flow through the body cooling fins and achieve substantially greater heat dissipation from the fan drive assembly, thus permitting greater fan speed for a given input speed.

摘要： The control of the coolant flow is accomplished through valving or by adjusting the pumping speed of a water pump and a water motor, or a combination of all three elements. During normal operation, where engine cooling is not required, the speed control coupling maintains a slow and constant water pump speed at all engine-operating speeds. The valve is maintained to stop coolant flow from entering the radiator while allowing coolant to flow through a heater. If engine cooling is required, the valve is actuated such that coolant is circulated to the engine and through the radiator. If air conditioning is required, the speed control coupling simply increases the water pump speed and the fan speed while the valve is set to bypass coolant flow to the engine. If air conditioning and engine cooling are required, the valve is actuated to allow coolant flow to the engine.

摘要： A stator and diffuser assembly is introduced between an engine cooling fan and engine. The stator acts increase the static efficiency per unit airflow of the axial fan by reducing the rotational component of air traveling through the fan and by directing the airflow in an axial direction towards the engine. The diffuser acts to increase the static efficiency per unit airflow of the axial fan used by decelerating the airflow, thereby providing more airflow to the engine at a given fan rotational speed. The stator and diffuser assembly thus decreases the amount of horsepower necessary to drive the fan at a given rotational speed and reduces noise.

摘要： An electronically-controlled viscous coupling is coupled to a water pump to control the coolant flow rate of engine coolant to an engine at a given engine speed to maximize fuel economy and minimize emissions. The viscous coupling has a stationary electrical coil that, when excited by electrical current, induces the driven disk to flex away from an input disk within the viscous, thereby increasing the size of the shear area, thereby decreasing the amount of torque produced to drive the water pump shaft and impellers that control the coolant flow rate. A carrier coupled to the back of the driven disk maximizes the amount of flex allowed to the driven disk, thereby assuring a maximum decrease in rotational speed of the impellers at a given engine speed and ensuring that the driven disk does not contact the stationary coil.

摘要： A system for fabricating fan blades wherein the assembly includes a flat hub plate having generally radially oriented notches defined therein intersecting the plate periphery. Individual blades each include a hub connection portion adjacent an inner end region which includes parallel flat portions angularly related to the general blade configuration interconnected by a transition portion. The flat blade portions are located upon opposite sides of the hub plate and the transition portion extends through the hub plate notch. The flat portions are attached to the hub plate, and by predetermining the position of the hub connection configuration on the blade, the fan characteristics can be predetermined and accurately duplicated. The system permits a standard set of tools to form a variety of sizes of fan blade components having various characteristics.
