摘要： An electronically-controlled viscous fan drive having a one-piece accumulator and reservoir located on the top side of the clutch. The accumulator also has a low pressure and high pressure fill hole for allowing movement of viscous fluid from the reservoir to a anti-bleedback chamber and into the operating and working chamber of the coupling during normal operation. A radially balance valve disk having a step up feature coupled to a spring and an actuator electronically controls movement of viscous fluid from the reservoir to the anti-bleedback chamber through the fill holes by energizing or deenergizing the spring based on engine operating conditions. The valve disk may be a one-piece or two-piece design. The accumulator is designed to prevent morning sickness associated with the flow of viscous fluid from the reservoir to the operating chamber during engine off situations.

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 present invention 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： 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.
