[0016] The following description is provided to disclose the present application so that those skilled in the art can implement the present application. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious modifications. The basic principles of the present application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present application.

[0017] The skilled in the art should understand that in the disclosure of the specification, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, the above terms cannot be understood as a limitation on the utility model.

[0018] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0019] Reference Figures 2 to 4 The embodiment of the present application provides a six-spoke wheel hub, which comprises a wheel hub body 10. Six connecting parts 11 are uniformly arranged on the outer circumferential side of the wheel hub body 10, and a connecting plate 12 extending in the radial direction of the wheel hub body 10 is arranged in each connecting part 11. The radial direction of the wheel hub body 10 is the vertical direction of the extension direction of the wheel hub cavity 101 of the wheel hub body 10. An open bolt hole 102 for mounting a T-shaped bolt is arranged on the connecting plate 12, and the open bolt hole 102 extends in the axial direction of the wheel hub body 10. The axial direction of the wheel hub body 10 is the extension direction of the wheel hub cavity 101 of the wheel hub body 10. In addition, the size of the opening 1021 of the open bolt hole 102 is greater than or equal to the maximum hole diameter size of the open bolt hole 102, so that when the T-shaped bolt is mounted to the wheel hub body 10, the stud portion of the T-shaped bolt can be directly inserted into the open bolt hole 102 from the position of the opening 1021 of the open bolt hole 102. Compared with the conventional way of inserting the T-shaped bolt from one end of the closed loop bolt hole, this structure can more conveniently and quickly install the T-shaped bolt, thereby effectively improving the installation efficiency of the T-shaped bolt. In addition, the top of the connecting plate 12 is provided with a limiting structure for limiting the bolt head of the T-shaped bolt in the rotation direction. Once the T-shaped bolt is installed in place, the T-shaped bolt can no longer rotate or deviate. When the clamping block is connected through the T-shaped bolt, only the clamping block needs to be rotated. The limiting of the T-shaped bolt by the limiting structure can ensure the stability of the T-shaped bolt installed on the wheel hub body 10 and the connection reliability between the two, avoiding the risk of easy tearing of the conventional closed loop bolt hole, being safer to use and having a long service life.

[0020] In one embodiment, the opening 1021 of the open bolt hole 102 is located at the outer side wall of the connecting plate 12, i.e. the side wall close to the outer side of the connecting part 11, so that the T-shaped bolt is more convenient to install.

[0021] In one embodiment, the opening 1021 of the open bolt hole 102 has the same size as the maximum hole diameter of the open bolt hole 102, while the outer side wall 111 of the connecting part 11 is provided with a clearance gap 103 communicating with the opening 1021 of the open bolt hole 102, and the clearance gap 103 has the same size as the opening 1021 of the open bolt hole 102. Compared with the way that the size of the opening 1021 is larger than the maximum hole diameter, the T-shaped bolt can be limited to a certain extent through the opening 1021 and the clearance gap 103, while the quick installation of the T-shaped bolt is not affected.

[0022] In one embodiment, the limiting structure includes a limiting baffle 21 and two limiting members 22, wherein the limiting baffle 21 is located at the inner side of the open bolt hole 102 and faces the open bolt hole 102, for limiting the bolt head at the inner side, and the two limiting members 22 are symmetrically distributed at the outer side of the open bolt hole 102, for limiting the bolt head at the outer side, so that the limiting space 201 for limiting the bolt head can be formed by the limiting baffle 21 cooperating with the two limiting members 22, to avoid the rotation or deviation of the T-shaped bolt.

[0023] Further preferably, the limiting member 22 is a limiting plate, and the outer side wall of the connecting part is extended from the top of the connecting plate to the opening of the open bolt hole, to form the limiting member, so that the existing structure can be fully utilized and improved on the basis of the existing structure, so that the six-spoke wheel hub is more easily manufactured, and the bolt head is limited in a surface contact manner, with a larger contact area and better limiting stability.

[0024] It should be understood by those skilled in the art that the embodiments of the utility model shown in the above description and the drawings are only examples and do not limit the utility model. The advantages of the utility model have been completely and effectively realized. The functions and structural principles of the utility model have been shown and explained in the embodiments, and the embodiments of the utility model can be any deformation or modification without departing from the principles.
