Embodiment Construction

[0010] In the figure, the invention includes a central shaft 1, a spoke 2, a bearing 3, a gland 4, a spring retaining ring 5, a dustproof ring 6, and a sealing ring 7. The two ends of the central shaft 1 are symmetrically installed and fixed through the bearing 3. Wheel spoke 2, a dust ring 6 is arranged between the inner side of the wheel spoke 2 and the central axle 1; at both ends of the central axle 1, a pressure cover 4 is fixedly installed through the spring retaining ring 5, and a pressure cover 4 is arranged between the pressure cover 4 and the wheel spoke 2. There is a sealing ring 7.

Abstract

The invention discloses a bicycle hub structure. Two ends of a centre shaft are symmetrically fixedly provided with spokes; a dust-proof ring is arranged between the inner side of each spoke and the centre shaft; two ends of the centre shaft are respectively fixedly provided with a gland by a spring check ring; and a seal ring is arranged between each gland and each spoke. The bicycle hub structure has the advantages of simple structure and low cost. Meanwhile, because the working environment of a bearing is completely in a sealing state, damage on a rolling part caused by foreign matters can be effectively prevented, and the bicycle hub structure is reliable to use and work and long in service life.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a structure of a bicycle wheel hub. Background technique [0002] At present, the wheel hub of a bicycle is generally composed of a central axle, a sleeve, a steel ball washer, a pin nut, and a spoke for fixing the spokes. The spokes are fixed at both ends of the sleeve, and the central axle runs through the sleeve Steel ball pads are installed in the annular grooves at both ends of the spokes, and the annular track of the steel ball pad is full of steel balls, and the steel balls are fixed on the steel ball pads with a specific pin nut. [0003] From the structure of the existing bicycle hub, it can be seen that the existing bicycle hub has the defects of complex structure and high cost. In addition, the bicycle hub of this structure also has the defects of high failure rate and low service life. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is t...
