A quick release hub assembly having an elongate hollow axle for receiving thereon a captively held rotatable wheel. For attachment and release, the assembly is provided with an insert mechanism, which fits within a tubular opening on a vehicle. The assembly includes an elongate rod threaded at one end and having a pivotable cam member and handle on the other end. A cam follower washer member is positioned on the rod between the handle and the wheel. The insert mechanism includes first and second cone members in facing relation with a split nylon ring in between the two facing cone surfaces. The cone members are received on the rod and are held in place thereon between the wheel and the threaded end by means of a locking nut. The parts are dimensioned and configured such that movement of the rod in the axial direction outwardly on pivoting of the handle toward the wheel urges the cone surfaces together thus moving the perimeter of the split nylon ring radially outwardly against The inner surface of the tubular opening to thereby lock the hub assembly in place relative to the vehicle. Conversely, pivoting of the handle away from the wheel moves the rod axially inwards to thereby relax the pressure on the nylon washer and permit ready release of the assembly. The cam handle is pivotable about a pivot axis parallel to the plane of the wheel and moves through an angle away from the plane of the wheel to apply (or relax) an axial force to the assembly for securing or release of the assembly.
