  • Low voltage interrupter for electric winch
    Patent number: 7262947
    Abstract: A low voltage interrupt for an electric winch prevents voltage decay of a battery due to excessive operation of the winch. If the battery voltage decays below a threshold, the low voltage interrupt disables the winch, allowing an alternator to recharge the battery. A voltage sense circuit determines the voltage of the battery. The sensed voltage is compared to a predetermined threshold. If the sensed voltage decays below the threshold, the low voltage interrupt generates an interrupt signal. The interrupt signal causes a relay to actuate, thereby interrupting current to the winch.

  • Roller disk brake for a winch
    Patent number: 7222700
    Abstract: A brake mechanism having a motor output shaft outputting a driving torque in a power-in and a power-out direction. A camming device operably couples the output shaft to a drive shaft for fixed rotation. A one-way clutch operably couples the drive shaft and a brake device. The brake device is normally in an engaged position that prevents rotation of the clutch device. During a holding maneuver, the one-way clutch, camming device, and brake device cooperate to prevent uncommanded movement. However, the nature of the one-way clutch permits free rotation during a power-in direction and the nature of the camming device permits free rotation during a power-out direction.

  • Hub assembly having a clutch ring travel limiter
    Patent number: 7143883
    Abstract: A wheel hub assembly is provided including a movable clutch ring for selective engagement between an engaged and disengaged position for providing driving torque from an axle shaft to a wheel hub. The clutch ring is in full-time engagement with external clutch teeth of the axle shaft and is movable to an engaged position with external clutch teeth of a coupler that is secured to the wheel hub. Furthermore, the coupler is provided with a travel limiter for preventing the clutch ring from traveling beyond a predetermined desired position along the coupler.

  • Utility winch
    Patent number: 6604731
    Abstract: A utility winch having a single planet gear assembly that commonly engages adjacent ring gears, one ring gear fixed and the other rotatable. The planet gears of the planet assembly have inner and outer portions that rotate together and have different diameters and different numbers of teeth, one ring gear engaged with an inner portion and a second ring gear engaged with an outer portion of the planet gears. Said ring gears matched to the respective planet gear portions and having different numbers of teeth and different diameters as required to achieve involute engagement of the ring gears and planet gears whereby the rotatable gear is caused to rotate at a substantially reduced rate of rotation. Said rotatable ring gear is fixed to the winch reel for reduced rotation of the reel.
