Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] refer to figure 1 and figure 2 , a high-strength bicycle hub, including a hub shell 1 and a main shaft 2, the two ends of the hub shell 1 are set on the main shaft 2 through bearings 3, the hub shell 2 includes a middle tube 4, the The middle tube 4 is provided with at least three or more axially arranged axial protrusions 5, and the axial protrusions 5 are axially distributed with spoke installation holes 6, and the plurality of spoke installation holes 6 are formed by the middle pipe. The midline is centrally symmetrical.

[0014] A plurality of axial ridges 5 are distributed at equal arc intervals along the radial direction of the outer ring of the middle tube.

[0015] The axial protrusions are integrated with the middle tube.

[0016] Usually, there are 3 to 10 axial convex lines; refer to figure 1 , there are 12 spoke mounting holes, 6 on each side, ...

Abstract

The invention relates to a high strength bicycle hub comprising a hub casing and a main shaft, wherein both ends of the hub casing are sleeved on the main shaft through bearings; the hub casing comprises a middle tube which is provided with at least more than three axial convex strips arranged axially; spoke installation holes are axially distributed in the axial convex strips; and a plurality of spoke installation holes are symmetrically arranged by regarding the midline of the middle tube as the center. The invention provides the high strength bicycle hub with the advantages of simplifying assembly procedures and improving the strength of rims.

Description

technical field [0001] The invention belongs to a bicycle flower hub. Background technique [0002] There are two discs on both sides of the bicycle hub, and there are holes on the discs to install the auxiliary rods. The length of the steel wires needs to be adjusted one by one, and the center of gravity is prone to deviation and ellipse during assembly. The assembly is time-consuming and laborious, and the strength of the rim is low. And along with the trend that the bicycle evolves into today's sports equipment by the means of transportation in the past, people also put forward higher requirement to the performance of bicycle, therefore, hub is as the main component of bicycle, and it seems very important to improve bicycle performance by changing hub structure. Needed. Contents of the invention [0003] In order to overcome the disadvantages of time-consuming and labor-intensive assembly of the existing bicycle hub and low strength of the rim, the present invention pr...
