ABSTRACT:
A spindle assembly for reliably locking a vehicle wheel to a vehicle. The spindle assembly includes a slotted sleeve that is engageable with a central opening of the wheel, to cooperate with a plurality of lugs in locking the wheel in place. The slotted sleeve incorporates a number of deflectable fingers, and a mandrel can be reciprocated along the sleeve's longitudinal axis, between an extended position and a retracted position. When the mandrel is in its extended position, the sleeve's deflectable fingers are moved to a position that allows the wheel to be removed and replaced, whereas when the mandrel is in its retracted position, the fingers are moved into engagement with the wheel, to positively lock the wheel in place. A compressible coil spring biases the mandrel to its retracted position, but the application of a positive hydraulic pressure to the spindle assembly overcomes this spring bias, to move the mandrel to its retracted position. The wheel thereby can be removed and replaced without the need for any supplementary tools. The spindle assembly has particular utility if it is combined with a jack mechanism, such that applying a pressurized fluid (liquid or gas) to the vehicle simultaneously activates both the jack mechanism and the spindle assemblies, to lift the vehicle's wheels off of the ground and simultaneously unlock the wheels.
