Abstract
A bicycle hub unit configured to be stably coupled to a frame of a bicycle includes a hub axle and a rotation restriction member. The hub axle is configured to be coupled to the frame of the bicycle. The rotation restriction member is configured to couple the hub axle to the frame so that rotation relative to the hub axle and the frame is restricted. At least one of the hub axle and the rotation restriction member has a cable guide structure configured to guide a cable, which electrically connects an electric component and an electronic component, in a region including the rotation restriction member in an axial direction parallel to a center longitudinal axis of the hub axle.
Claims23
A bicycle hub unit comprising:
- a hub axle configured to be coupled to a frame of a bicycle;
- a freewheel rotatable about the hub axle;
- and
- a rotation restriction member configured to couple the hub axle to the frame so that rotation relative to the hub axle and the frame is restricted,
- at least one of the hub axle and the rotation restriction member including a cable guide structure configured to guide a cable in a region including the rotation restriction member in an axial direction parallel to a center longitudinal axis of the hub axle, and
- the cable electrically connecting an electric component and an electronic component, the electronic component being arranged to at least partially overlap a portion of the freewheel in a radial direction of the hub axle, the portion being configured to support a rear sprocket of the bicycle.
A bicycle hub unit comprising:
- a hub axle configured to be coupled to a frame of a bicycle;
- a freewheel rotatable about the hub axle;
- a rotation restriction member configured to couple the hub axle to the frame so that rotation relative to the hub axle and the frame is restricted;
- a hub body provided on the hub axle to be rotatable about the hub axle;
- and
- an electric power generator that generates electric power based on rotation of the hub body relative to the hub axle,
- at least one of the hub axle and the rotation restriction member including a cable guide structure configured to guide a cable in a region including the rotation restriction member in an axial direction parallel to a center longitudinal axis of the hub axle, and
- the cable electrically connecting the electric power generator to an electronic component, the electronic component being arranged to at least partially overlap the freewheel in a radial direction of the hub axle.
A bicycle hub unit comprising:
- a hub axle coupled to a frame of a bicycle, and the hub axle including a recess, the recess including a groove that is provided in an outer circumferential surface of the hub axle and extends in an axial direction parallel to a center longitudinal axis of the hub axle;
- and
- a rotation restriction member including a first engagement portion engaging with the recess of the hub axle,
- the rotation restriction member being configured to couple the hub axle to the frame so that rotation relative to the hub axle and the frame is restricted, and
- the rotation restriction member being detachably attached to the hub axle.
A bicycle hub unit comprising:
- a hub axle configured to be coupled to a frame of a bicycle;
- and
- a rotation restriction member configured to couple the hub axle to the frame so that rotation relative to the hub axle and the frame is restricted,
- the rotation restriction member including a cable guide structure configured to guide a cable that electrically connects an electric component and an electronic component,
- the cable guide structure being configured to guide the cable in a region including the rotation restriction member in an axial direction parallel to a center longitudinal axis of the hub axle, so that the cable is located at an outer side of an inner surface of the frame, the inner surface being located closer to a center line of the frame than an outer surface of the frame with respect to the axial direction of the hub axle, and
- the cable guide structure being further configured to guide the cable in a radial direction of the hub axle between the inner surface and an outer surface of the frame opposite to the inner surface.
A bicycle hub unit comprising:
- a hub axle coupled to a frame of a bicycle;
- a hub body provided on the hub axle to be rotatable about the hub axle;
- an electric power generator generating electric power based on rotation of the hub body relative to the hub axle;
- a freewheel rotatable about the hub axle;
- and
- a guide member provided on the hub axle so that rotation relative to the hub axle is restricted, the guide member including a cable guide structure configured to guide a cable in the axial direction of the hub axle so that the cable is located at an outer side of an inner surface of the frame, the inner surface being located closer to a center line of the frame than an outer surface of the frame with respect to an axial direction parallel to a center longitudinal axis of the hub axle, and
- the cable electrically connecting the electric power generator and an electronic component, the electronic component being arranged to at least partially overlap the freewheel in a radial direction of the hub axle.
