ABSTRACT:
A free-wheel hub transmission mechanism includes an axle, and an aluminum hub barrel and a driving barrel which are rotatably mounted on the axle. The driving barrel which carries a sprocket wheel has a threaded body portion extending into the hub barrel to connect to a coupling socket which transmits the rotation of the driving barrel to a reinforcing hollow body. The reinforcing hollow body is provided in and fixedly coupled to the hub barrel. The coupling socket is movable toward and frictionally engageable with the reinforcing hollow body upon rotation of the driving barrel in one direction and is disengageable from the reinforcing hollow body upon rotation of the driving barrel in another direction.
