US Classification:

192 36

Abstract:

A hub lock device for converting a vehicle between four-wheel and two-wheel drive, the hub lock being actuated by automatic actuation or manual actuation. A sliding clutch ring that engages and disengages the wheel and axle is trapped in a cage. An extender bar from the cage has a hook end that hooks over the edge of a nut. The nut is moved between inner and outer positions by a manual dial. In the outer position, the nut forces the cage, through engagement of the hook end, to the position whereat the clutch ring is urged to interlock the axle and wheel. In the inner position the nut releases the cage, i. e. , the hook can extend between an inner and outer position, to permit automatic actuation. The automatic actuation includes cam actuation wherein the spindle nut provides the cam actuator and brake surface for secondary cam actuation. The spindle nut is locked to the spindle with a lock pin projection extended from a thrust ring that enhances turning of the drive gear on the axle relative to the spindle nut in four-wheel drive.
