ABSTRACT:
A winch (10) is powdered by a motor (20) mounted at one end of a drum (12) through a three-stage planetary drive train (26) disposed adjacent the opposite end of the drum (12 ). The drive train (26) includes elongate drive shaft (25) which extends longitudinally through the interior of the drum (12) toward the motor (20). A brake-clutch assembly (24), disposed within the interior of the drum (12) operably interconnects motor (20) and drive shaft (25). The brake-clutch assembly (24) automatically operates in response to the magnitude and direction of the torque being transmitted between motor (20) and drive shaft (25). In operation, the brake-clutch assembly (24) permits the drive shaft (25) to rotate relative to and power the drum (12) to reel in the loaded drum cable and then frictionally locks the drive shaft (25) to the inside diameter of the drum (12) to hold the load on the drum cable when motor (20 ) is stopped. The brake-clutch assembly (24) also frictionally bears against the inside diameter of the drum (12) when motor (20) is operating in the reverse direction to reel out the load attached to the drum cable thereby controlling the rotational speed of the drum (12) to prevent it from overrunning the motor (20).
