A free wheel hub mechanism made up of a body secured to a wheel, an inner race secured to an axle shaft and rotatable therewith, means for engaging the inner race with the body only upon rotation of the shaft and for otherwise permitting free rotation of the body. A shoe receiving member is secured to a spindle sleeve of the axle shaft and has a receiving surface which crosses the axle shaft at substantially a right angle. A shoe means maintains the engaging means in its engaged condition, the shoe means having a sliding surface which crosses the axle shaft at a substantially right angle, and a spring biases the sliding surface of the shoe means against the receiving surface of the shoe receiving member.

Free wheel hub mechanism

A free wheel hub mechanism including a body fixed to a wheel, an annular clutch continuously engaged with the body, an interengaging member connected to an axle shaft rotatable therewith and engageable with the annular clutch, a follower operatively connected to the annular clutch and axially movable in response to the rotation of a manual handle, and a nut fixed to the axle shaft for supplying a preload force on a taper bearing between a housing and the axle shaft.

A free wheel hub apparatus for vehicles having a wheel hub and an axle shaft includes a body integrally rotated with the wheel hub, an inner member disposed within the body and integrally rotated with the axle shaft, a bearing member interposed between the inner member and the body, a plurality of rollers interposed between the inner member and the body, a cage for supporting the rollers, and frictional means for engaging or disengaging the cage with or from a knuckle or the body according to the axial movement of the cage by a handle.
