In the present application, considering that the amount of deformation of the nut seat 11 can represent the structural strength of the nut seat 11, the amount of deformation (including other variations such as in the thickness direction) of the nut seat 11 of the present application is reduced from the conventional 0.084mm to 0.077mm, and the rigidity performance of the nut seat 11 is effectively improved. Specifically, referring to fig. 4 of the specification, fig. 4 is a graph comparing the deformation amount of the nut seat of the conventional spoke with the deformation amount of the nut seat 11 of the present application, and as can be seen from fig. 4, the deformation amount of the nut seat 11 of the present application is smaller than that of the conventional nut seat in the case of different loading forces.

As shown in fig. 2 and 3, the nut holder 11 includes a sub-mounting plate 111 and a tapered ring plate section 112 connected to each other, wherein a mounting hole 1111 is opened in the sub-mounting plate 111, and the tapered ring plate section 112 is disposed to be gradually enlarged in a direction away from the sub-mounting plate 111.

In this way, a smooth transition at the junction of the central mounting disk 10 and the support ring plate 20 is ensured.

Further, for spokes 2 of different models, in the processing process of the nut seat 11, the nut seat 11 is set to be in a structure form extending in a tower shape in the axial direction of the mounting hole 1111, so that the nut seat 11 can be well extended, the phenomenon that the material is suddenly thinned due to large bending of the material in the stamping process and the thickness of the nut seat 11 is thinned due to large deformation in the thickness direction can be avoided, and the structural strength of the nut seat is ensured.

As shown in fig. 1 to 3, a center through hole 13 is formed in the center mounting plate 10, the nut holder 11 is positioned on the outer circumferential side of the center through hole 13, and the mounting hole 1111 is concentrically arranged with the center through hole 13. Thus, the provision of the center via 13 is used for connection of the wheel to the axle.

As shown in fig. 1, the center mounting plate 10 has a plurality of nut seats 11, the plurality of nut seats 11 are provided at intervals around the outer periphery of the center through hole 13, and each nut seat 11 has a mounting hole 1111. Thus, the plurality of mounting holes 1111 are provided for fastening and mounting the wheel and the axle.

As shown in fig. 1, the hole centers of the mounting holes 1111 are located on the same circle. In this way, when the wheel is connected with the axle, the connection reliability between the wheel and the axle is ensured, and the uniform stress between the wheel and the axle is ensured.
