[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only to represent selected embodiments of the present application.

[0023] In the description of the present application, the meaning of "a plurality of" is two or more than two, unless otherwise explicitly and specifically limited.

[0024] Embodiment one:

[0025] Referring to Figures 1-2 The spoked wheel assembly shown in the figure, including the wheel rim part 1 and the hub mounting part 3, a plurality of spokes 2 are connected between the wheel rim part 1 and the hub mounting part 3, the number of spokes 2 will affect the performance of the wheel set, including strength, rigidity, weight and aerodynamic characteristics, therefore, the number of spokes 2 is not fixed, but is determined according to the type and purpose of the bicycle, the present application does not make specific limitation, the wheel rim part 1, the hub mounting part 3 and the spoke 2 are integrally formed or assembled as a whole, and all are carbon fiber material;

[0026] The spoke 2 contains the connecting part 22 at both ends and the wind breaking part 21 in the middle, the connecting part 22 connects the wind breaking part 21 with the wheel rim part 1 or the hub mounting part 3, the wind breaking part 21 is water drop-shaped in cross section, wherein the outline of the water drop shape and the preferred data of the length-width ratio value are prior art, and will not be described in detail, the water drop-shaped wind breaking part 21 has the best wind breaking effect compared with other shapes, the wind breaking part 21 includes the wind breaking end 211 and the leeward end 212, the wind breaking end 211 is a round end of water drop shape, and the leeward end 212 is a sharp end of water drop shape, when the rider rides forward, the airflow first contacts the wind breaking end 211, and the airflow breaks through the wind breaking end 211, part of the airflow passes through one side of the leeward end 212, and another part of the airflow passes through the other side of the leeward end 212, so as to separate the resistance generated by the airflow, divide and weaken the larger airflow, and reduce the wind resistance. The wind resistance coefficient of the water drop shape is one of the known minimum values, which is lower than that of the circular or flat cross section of the spoke 2, when a plurality of wind breaking parts 21 rotate at the same time, the airflow can be divided into several parts, so that the resistance received by the bicycle is reduced, so that the rider is easier to break the wind when riding, and the resistance received by the bicycle is reduced.

[0027] And the wheel rim part 1, the hub mounting part 3 and the spoke 2 are integrally formed or assembled as a whole, the connection structure of the spoke 2 and the wheel rim part 1 and the hub mounting part 3 is simplified, the connection head is not needed for connection like the traditional connection structure, the structural strength is improved, and the integrally formed structure avoids the spoke 2 from being easily led to uneven tension, wheel rim out-of-round and the like if adjustment is not in place during installation.

[0028] The section of the connecting part 22 is circular, which is convenient for processing and manufacturing of the connection part of the spoke 2 and the wheel rim part 1 or the hub mounting part 3, and the side of the wind-breaking end 211 away from the leeward end 212 is flush with the edge of the connecting part 22, and the overall wind-breaking surface of the spoke 2 is located on a line.

[0029] The transition part 23 is further arranged between the wind-breaking part 21 and the connecting part 22, the transition part 23 gradually changes from the water-drop shape of the wind-breaking part 21 to the circular shape of one end of the connecting part 22, and the whole is more beautiful.
