An integrated air compressor and winch is provided that utilizes a 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.

Integrated air compressor and winch

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 wheel end assembly including a live spindle secured to a wheel hub at an outboard end. A bearing surrounding the spindle and abutted against a shoulder on the spindle. Said bearing preloaded by a retention structure that slidably engages the bearing to compress the bearing against the shoulder. A clutch ring slidably engages splines associated with the live spindle and with an axle portion to connect and disconnect the axle to the live spindle and accordingly the wheel hub.

Retention mechanism for vehicle wheel assembly

An annular actuator for moving a member axially to couple and un couple a drive member with a driven member of a vehicle drive train. The actuator encircles the drive and driven member. The actuator has a housing to which a diaphragm is mounted. A spring biases the diaphragm to move in one axial direction and withdrawal of air forces the diaphragm to move in the opposite axial direction. A shifting fork coupled to the diaphragm moves a clutch ring in the one axial direction to be coupled with only one of the drive and driven members and is coupled with both the drive and driven members when moved in the opposite direction. The actuator defines a sealed chamber that is totally non-rotatable with relative movement occurring between the shifting fork and the clutch ring.

Pneumatic annular actuator

A pulse actuated clutch and control arrangement for coupling and decoupling a drive line of a vehicle relative to a wheel such as when shifting between two-wheel and four-wheel drive modes. The pulse actuated clutch has a coupling member that is permanently engaged with one of a driven member and a driving member. The coupling member is movable in a first direction to engage one of the driven and driving members and is movable in a second direction to engage both the driven and driving members. The coupling member is moved in the second direction by a first pulse of air pressure applied thereto. Formations of the piston assembly and the driven member cooperatively latch the piston in the second position to maintain the coupling member in engagement with both the driven and driving members following first pulse of air pressure. A second, greater magnitude pulse of air pressure moves the primary piston further to unlatch the piston and uncouple the driven member from the driving member. The illustrated control arrangement incorporated into a general purpose control module for a vehicle to accomplish pulse actuated control over the clutch mechanism in coordination with other vehicle control activities. The control arrangement makes use of timers and references vehicle conditions to ensure mechanical transition of the pulse actuated clutch mechanism fully into a desired state.
