A power management module for a winch system comprises an overload and low voltage interrupt module within a housing. The overload interrupt determines operating current for the winch system and provides an interrupt signal when the current is greater than a threshold. The low voltage interrupt determines voltage of a power source and provides an interrupt signal when the voltage is less than a threshold. A method of operating the power management module comprises determining operating current of the winch system with an overload interrupt module and voltage of a vehicle power source with a low voltage interrupt module. The overload and low voltage interrupt modules are located within a housing. The overload interrupt provides an interrupt signal when the operating current is greater than a threshold. The low voltage interrupt provides an interrupt signal when the voltage is less than a threshold.
A portable pulling tool is provided including an integrally formed one-piece gear case for positioning all of the gear train components. The gear train includes a combination of helical gears and a differential planetary gear unit in a unique configuration. A motor control system is provided to automatically shut off the motor when a predetermined current load is detected. A multi-segment LED is provided to indicate to the user the amount of load that is being applied.

A winch assembly includes a housing member, a drum rotatably coupled to the housing member, a drive shaft extending through the drum and into the housing member, a gear train located within the housing member, and an actuation mechanism. The gear train includes a sun gear driven by the drive shaft, a ring gear, and a planetary gear assembly driven by the sun gear and including a planetary gear rotatably coupled to a carrier plate and engaged with the ring gear. The actuation mechanism includes a locking member displaceable between first and second positions and a biasing member having a radially extending arm engaged with the locking member to provide displacement between the first and second positions. The locking member rotationally fixes the ring gear relative to the housing member in the first position and allows relative rotation between the ring gear and the housing member in the second position.
An integrated air compressor and winch is provided that utilizes a single source of rotary motive power for driving both a winch drum and compressor mechanism. The integrated air compressor and winch is preferably provided with a gear case that is operable to provide an appropriate gear reduction for driving the winch drum while providing an appropriate drive speed for operating the compressor.
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.
B60T 1/00 - Arrangements of braking elements, i.e. of those parts where braking effect occurs
B60T 13/00 - Transmitting braking action from initiating means to ultimate brake actuator with power assistance or drive; Brake systems incorporating such transmitting means, e.g. air-pressure brake systems
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.
