Abstract
Novel lightweight bicycle hub comprises a hub shell, a main shaft and a ratchet wheel. The two end of the hub shell is sleeved on the main shaft by a bearing. The ratchet wheel is disposed one end of the hub shell, and a fixed chainring is disposed on the other end of the hub shell. The hub shell comprises a tube which is provided with a disc chuck. Spokes mounting holes are formed on the disc chuck. The tubes are symmetrically distributed. The pipe diameter of the tube is large on both sides and small in the middle. The novel lightweight bicycle hub has the advantages of being capable of taking intensity and portability into consideration, and saving material.
Description
Technical field
The utility model belongs to a kind of bicycle hub.
Background technology
Common bicycle hub is only paid attention to working strength, and is light not.Along with the development of society, road construction ground is more smooth, and people are more and more obvious to the light requirement of bicycle, and the weight, the while economical with materials that alleviate colored hub under the prerequisite of guaranteed performance seem necessary.
Summary of the invention
Can't take into account intensity and portability, the more deficiency of materials for what overcome existing bicycle hub, the utility model provides a kind of novel light bicycle hub that can take into account intensity and portability, economical with materials.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of novel light bicycle hub, comprise hub shell body, main shaft and ratchet-type flywheel, described hub shell body two ends are contained on the main shaft by bearing carrier ring, one side of described hub shell body is installed the ratchet-type flywheel, and the opposite side of described hub shell body is installed the fixed type gear piece, and described hub shell body comprises middle pipe, described middle pipe is provided with floral disc, described floral disc is provided with the spoke mounting hole, and described middle pipe is symmetric, and the caliber both sides of middle pipe are large, middle little.
Further, described floral disc is provided with lightening hole, and the radian intervals such as described lightening hole are arranged on described floral disc one circle.
The beneficial effects of the utility model are mainly manifested in: improved the structure of hub shell, reduced the caliber of middle pipe, set up lightening hole on the floral disc, effectively alleviated the weight of colored hub under the prerequisite of guaranteed performance, saved material.
