Abstract
A fan drive with high torque release embodying the concepts of the present invention is adapted to disengage the fan drive under high torque conditions. The fan drive includes an input shaft member and an output shaft member. A torque transfer device operatively connects the input shaft member with the output shaft member. A spring apply mechanism is provided for engaging the torque transfer device at low speeds and under low torque loading, and a centrifugal apply mechanism is provided for maintaining engagement of the torque transfer device under higher operating speeds and at properly anticipated torque loading. A release mechanism substantially disengages the torque transfer device upon the application of higher than desired torque loading conditions.
