Abstract
A bicycle real wheel hub includes pulling spokes and static spokes connected to the disks thereof. The hub includes a tubular portion with two disks respectively connected to two ends of the tubular portion. Multiple protrusions protrude from the inner side of each disk. The head of each pulling spoke is secured to the protrusion corresponding thereto. The head of each static spoke is secured to the disks. The heads of the pulling spokes are located closer to the middle point of the tubular portion than the heads of the static spokes. When the hub rotates, the static spokes provide strength in the axial direction of the hub, and the pulling spokes have strong tension so that the hub bears higher torque.
Claims5
A bicycle real wheel hub comprising:
- a tubular portion and two disks respectively formed with two ends of the tubular portion, each disk having an inner side and an outer side, the inner side facing the tubular portion and located opposite to the outer side;
- multiple protrusions protruding from the inner side and evenly spaced apart from each other, a separation space formed between adjacent protrusions, each protrusion having a first hole defined therethrough, two open ends of each of the first holes facing the separation space corresponding thereto;
- each disk having multiple second holes defined therethrough and communicating with the inner and outer sides, one of two open ends of each second hole communicating with the inner side and facing the separation space;
- multiple pulling spokes each having a head and a shank, the head of each pulling spoke secured in the first hole of the protrusion corresponding thereto, the shank of each pulling spoke extending through the separation space and extending outward, and
- multiple static spokes each having a head and a shank, the head of each static spoke located at the inner side and stopped by a periphery of the second hole, the shank of each static spoke extending through the disk and extending outward.
