Example 1

As shown in fig. 1, the wheel set of the ADV motorcycle tubeless spoke type aluminum alloy rim includes a rim 1, a hub 2 and spokes 3 for a front wheel. The spokes 3 are connected between the rim 1 and the hub 2.

Referring to fig. 2, two axial sides of the rim 1 are respectively provided with spoke joint parts i 4, the spoke joint parts i 4 are erected outwards in the radial direction, and spoke outer end mounting holes 5 are formed in the spoke joint parts i 4.

As shown in fig. 3, the spoke 3 comprises an outer end portion 10, an intermediate portion 11 and an inner end portion 12. The outer end portion 10 is connected to the radially outer side of the intermediate portion 11, and the inner end portion 12 is connected to the radially inner side of the intermediate portion 11. The spoke 3 further comprises a cap 13. Cap head 13 engages threads on inner end 12. The cap head 13 is provided in the hub 2 (see fig. 1).

As shown in fig. 3, the outer end 10 of the spoke 3 is also provided with a projection 14, the projection 14 extending transversely. As shown in FIG. 1, the outer ends 10 of the spokes 3 are integrated into the spoke attachment portion I4. specifically, the outer ends 10 of the spokes 3 are inserted into the spoke outer end mounting holes 5 and are held against the outer side surface of the rim 1 by the protrusions 14. In this example, the protrusion 14 is located in the spoke outer end mounting hole 5, and the spoke outer end mounting hole 5 is a stepped hole, so that the effect of hiding the protrusion 14 is achieved, and friction between the protrusion 14 and the tire is avoided. In other embodiments, the outer ends of the spokes 3 can be welded to the spoke outer end mounting holes 5 by welding.

As shown in FIG. 2, the spoke attachment portions I4 are provided with a bead portion 6 on the axially inner side thereof, and a recessed portion 7 is provided between the bead portions 6. The inner rim of a tire (not shown, this example is of the tubeless type, i.e. a tire referred to as a cover) is disposed on the tire seat portion 6 and is axially and outwardly urged against the inner side surface of the spoke attachment portion I4. The recess 7 on the one hand increases the strength of the rim 1 and on the other hand the space within the recess 7 forms part of the inner cavity of the tire. As shown in fig. 1, a valve hole 19 is opened on the concave portion 7 of the rim 1 for placing an air nozzle of a tire.

As shown in FIG. 1, the spoke attachment portion I4 is provided with a beveled edge 15, and the spoke outer end mounting holes 5 are located in the slope of the beveled edge 15. The bevel 15 is angled both radially and axially. The beveled edge 15 contributes to reducing the friction between the rim 1 and the tyre.

As shown in FIG. 1, the two axial sides of the hub 1 are respectively provided with spoke joint parts II 8, and spoke inner end mounting holes 9 are formed in the spoke joint parts II 8. The aforementioned cap head 13 is disposed in the spoke inner end mounting hole 9, and an internally threaded hole in the cap head 13 is engaged with threads on the inner end 12 of the spoke 3, and the spoke 13 can be tightened by rotating the cap head 13.

As shown in fig. 1 and 3, the cap head 13 is provided at the outer circumference thereof with a wrench holding plane 16, and the wrench holding plane 16 is located outside the spoke inner end mounting hole 9, thereby facilitating a wrench to externally hold the cap head 13 and rotate the cap head 13.

In order to quickly mount the spokes 3, the inner end of the cap head 13 is also provided with an inner hexagonal hole 17.

As shown in FIG. 1, a single spoke 3 is connected between a spoke attachment portion I4 on one axial side and a spoke attachment portion II 8 on the other axial side to form an intersection for improving structural stability.

For better support of the rim 1, the outer ends 10 of the spokes 3 also have a bend, see fig. 3.

As shown in FIG. 1, two sets of spokes 3 are arranged between a single spoke-engaging portion II 8 and a corresponding spoke-engaging portion I4, and the two sets of spokes 3 are deflected in opposite directions in the circumferential direction, so that the structure is more stable. In fig. 1, c and d are each one of the two sets of spokes 3.

The connecting points of the spokes 3 of each of the two groups of spokes 3 on the spoke joint part II 8 are adjacent to each other to form a similar V shape, thereby facilitating the installation and improving the structural strength.

The connecting points of the two groups of spokes 3 on the spoke joint part I4 on one side of the rim 1 are distributed at equal intervals on the circumference, so that the stress capacity of the structure is more balanced.

As shown in fig. 3, in this example, a set screw 18 is further provided in the cap head 13. The set screw 18 is a headless screw, generally cylindrical, with a hexagonal socket at one end and threads on the periphery that mate with the threaded hole in the cap head 13. B' in fig. 3 is a left side view of b. The fastening screw 18 is screwed into the cap head 13 from the left side of the small drawing b in fig. 3 to the right, and the inner end parts of the spokes combined in the cap head 13 are tightly pressed, so that the spokes are not easy to loosen after being used for a long time.

Example 2

As shown in fig. 4, 5 and 6, the embodiment 2 of the present invention, the ADV motorcycle tubeless spoke type aluminum alloy wheel set of this embodiment is used for the rear wheel, and has substantially the same design concept as the front rim wheel set of the embodiment 1, and the main difference from the embodiment 1 is that the hub 2 has an axial eccentric distance to meet the installation requirement of the rear wheel, and accordingly, the spokes 3 with two different length specifications, e and f in fig. 6 are the spokes 3 with two length specifications.

In summary, in the ADV motorcycle tubeless spoke type aluminum alloy wheel set of the present embodiment, one end of the spoke 3 with the hat head 13 is connected to the hub 2, and the other end of the spoke 3 with smaller volume is connected to the rim 1, so as to facilitate the reduction of the rim 1. In addition, the spokes 3 are connected in a cross way between two axial sides of the rim 1 and two axial sides of the hub 2, and the spokes 3 connected to one side of the rim 1 and the corresponding side of the hub 2 are provided with two groups, and the two groups of spokes 3 form a V shape in opposite directions of circumferential deflection to improve the structural strength. Furthermore, the set screw 18 in the cap head 13 makes it less likely that the spoke 3 will loosen after prolonged use.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
