Wheel hub clutching mechanism
 A wheel hub clutching mechanism includes an internally splined body, and a clutch ring which is adapted to be meshed with a shaft driven pinion and is resiliently connected by means of a connecting spring to a follower which, in turn, is controlled by means of a rotatable cam. The follower and the clutch ring are biased toward the locked positions thereof by means of a compression spring when the cam is rotated to its locked position by means of a manually operated handle, and the clutch ring is retracted to the free position thereof together with the follower when the cam is rotated to its free position by means of the handle. A pinion supporting member is also interposed between the shaft driven pinion and the body, the splines of the body being formed so as to be substantially parallel to the shaft axis.
