Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example one

As shown in fig. 1 to 3, the present embodiment discloses a connecting structure of an integrated spoke assembly and a hub, comprising: a hub 1, two sets of integral spoke components 2 and two sets of upper covers 3.

Referring to fig. 5 and 6, the hub 1 includes a hub body 11 and flanges 12 at both ends of the hub body 11. The inner end of the flange 12 is provided with a mounting platform 13, the mounting platform 13 and the flange surface form a step surface T, and the shaft at the outer end of the mounting platform 13 is provided with an external thread 14. The external thread 14 is provided with at least two turns of active thread.

As shown in fig. 7 and 8, the one-piece spoke assembly 2 includes a connecting ring 3 and a plurality of spokes 4 circumferentially connected to the connecting ring 3, wherein the spokes 4 and the connecting ring 3 are made of carbon fiber material by integral molding. The circumferential side wall of the connecting ring 3 is provided with a plurality of groups of spokes 4, each group of spokes 4 comprises two spokes 4 which are arranged in an up-down overlapping manner, and the included angle alpha between the two spokes 4 which are arranged in the up-down overlapping manner is 115-125 degrees. Each spoke 4 is tangential to the connecting ring 3 in the circumferential direction. As shown in fig. 9, the spokes 4 are arranged obliquely inward at an angle β of 3 ° to 10 °. The design can ensure that the tension of the spokes 4 is proper and the force is uniform.
