ABSTRACT:
An electronically-controlled fluid coupling device having a front mounted fan and electrical actuation without a tethered harness. The fluid coupling device combines an inverted viscous clutch, drive pulley and a split electromagnetic actuator package. In this arrangement, the electrical portion of the split electromagnetic actuator is not physically attached to the fan drive, but is instead mounted to a stationary member. The remaining actuator components are integral to the fan drive and are composed of only mechanical parts. The inverted clutch arrangement having remote electronic control allows three output modes: engaged, partially engaged, or disengaged.
