ABSTRACT:
A winch assembly (11) comprises a rotary input shaft (15) connected to a pair of first and second gears (21,22) for rotating the gears in opposite directions. First and second friction clutches (23,24) are adapted to selectively connect a rotary output shaft (20) with the first and second gears, respectively, for establishing a drive connection from the input shaft to the output shaft during the reel-out (RO) and reel-in (RI) modes of operation of the winch assembly. An overrunning one-way clutch (33) is interconnected between the first and second gears for normally permitting the gears to rotate in opposite directions, but will lock-up when a torque load imposed on the output shaft during the reel-in mode of operation exceeds the input torque to the winch assembly by the input shaft.
