Abstract
A hub lock for a vehicle having a hub lock housing assembly that is pre-assembled and then assembled as a unit to the vehicle's axle, spindle and wheel hub. The sub-assembly arrangement is provided by splitting the functions of the vehicle's drive gear mounted on the end of the vehicle's axle. An inner drive gear member (also referred to as a sleeve or spacer) is mounted to the axle end to secure the axle on the spindle. An outer drive gear that slidably fits onto the inner drive gear provides the direct connection to the clutch ring of the hub lock. The inner drive gear is pre-assembled to the axle and the outer drive gear enables the hub lock housing assembly to be pre-assembled and as a unit to slidingly mount onto the vehicle. A dial used to manually retract the clutch ring into engagement against spring resistance is provided with a spring assist that is spring loaded when the dial is rotated to the disengaged position.
