Abstract
A NOVEL BICYCLE HUB WHICH INCORPORATES AT LEAST ONE UNIDIRECTIONAL CLUTCH/BEARING/FREEWHEEL OF THE HYPERBOLOIDAL TYPE AS AN INTEGRAL COMPONENT. THE INVENTION IS COMPRISED GENERALLY OF AN ORDINARY HUB MEMBER HAVING A PAIR OF OPPOSED PARALLEL FLANGES DEFINING A PLURALITY OF APPERTURES THROUGH WHICH ARE DISPOSED A SERIES OF SPOKES FOR CONNECTING THE HUB MEMBER TO A RIM. IN ONE EMBODIMENT, THE HUB IS LOCATED RELATIVE TO THE AXIS BY A PAIR OF BALL BEARING ARRANGEMENTS AND RETAINING NUTS IN A MANNER TO BE SET FORTH HEREINBELOW.IN A FIRST EMBODIMENT, THE HUB MEMBER RECEIVES CORRESPONDINGLY THREADED SHOULDER PORTION CONNECTED TO THE OUTER RACE MEMBER OF THE HYPERBOLOIDAL TYPE FREEWHELL. THE INNER RACE MEMBER OF THE FREEWHEEL IS SANDWICHED BETWEEN ONE OF THE AFOREMENTIONED BALL BEARING ARRANGEMENTS, AND THE SPROCKET OR SPROCKETS CONNECTED TO THE INNER MEMBER.THE ORIENTATION OF THE INNER AND OUTER BALL BEARING RACES IS SELECTED SUCH THAT THE INNER AND OUTER RACE SURFACES OF THE HYPERBOLOIDAL FREEWHEEL ARE NORMALLY BIASED INTO POSITIVE ENGAGEMENT WITH THE CYLINDRICAL THRUST TRANSMITTING ROLLERS USED WITH THE FREEWHEEL. BY "POSITIVE" ENGAGEMENT IS MEANT THAT THE ROLLERS ARE ALL DISPOSED AT A SMALLER ANGLE WITH RESPECT TO THE SUBDERIVATIVE HYPERBOLOIDAL INNER RACE SURFACE OF REVOLUTION ALONG A GENERATOR OF THE INNER FACE SURFACE AND, IN ADDITION, EACH MAKING LINE CONTACT WITH THE SUBDERIVATIVE HYPERBOLOIDAL OUTER RACE SURFACE OF REVOLUTION ALONG A GENERATOR OF THE OUTER RACE SURFACE.(FIG 1)
