Description

Technical Field

[0001] The utility model relates to the technical field of spoke wheels, in particular to a spoke installation structure and a spoke wheel. Background Art

[0002] Spoke wheels are often used in motorcycles, bicycles, etc. The spoke wheels mainly include a hub, a rim, and spokes connecting the hub and the rim. The deformation of the rim and the spokes can absorb impact, meet the shock absorption needs, and also achieve lightweight requirements.

[0003] The spoke installation structure of a conventional spoke wheel is that one end of the spoke is fixedly connected to the rim, and the other end is fixedly connected to the hub. In order to facilitate installation, the spokes of this structure have assembly margins at both ends. When the spokes are subjected to force, they are very likely to become loose, thereby greatly reducing the load-bearing performance of the spoke wheel; some other spoke wheels have segmented spokes, where two spoke sections are respectively connected to the rim and the hub, and then an intermediate connecting strip is used to securely connect the two spoke sections and maintain a certain tension. Although the spokes of this structure are firmly and reliably connected, their installation is cumbersome and assembly and disassembly is extremely inconvenient. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0027] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0028] See also Figures 1 to 4 As shown, the preferred embodiment provides a spoke mounting structure, including a rim 1, a hub 2 and spokes 3. In particular, a raised portion 4 is provided on the circumferential inner surface of the rim 1, a mounting groove 5 is provided in the raised portion 4, a limiting block 6 is embedded in the mounting groove 5, a spoke cap 7 is passed through the hub 2, a first end of the spoke 3 is limited and fixed by the limiting block 6, and a second end of the spoke 3 is threadedly connected to the spoke cap 7.

[0029] Therefore, the spoke installation structure adopts a spoke 3 installation form in which one end is stopped by the limit block 6 and the other end is fixed by a thread, which not only makes the spoke 3 easy to install, but also ensures the reliable assembly of the spoke 3. Specifically, the convenient installation is reflected in that it is only necessary to pass the first end of the spoke 3 through the limit block 6, insert the limit block 6 into the installation groove 5, and then tighten the second end of the spoke 3 with the spoke cap 7; the reliable assembly is reflected in that the first end of the spoke 3 is locked, the second end of the spoke 3 is threadedly connected with the spoke cap 7, and the spoke cap 7 is tightened to ensure that the spoke 3 is firmly and reliably connected to the rim 1 and the hub 2.

[0030] In particular, a notch 8 is formed on the end surface of the protrusion 4 facing the rim 1, and the stopper 6 is inserted into the mounting groove 5 through the notch 8. The end surface insertion method is adopted, which is more convenient for the installation of the stopper 6, and the insertion direction of the stopper 6 is not in the same plane as the force direction of the spoke 3, so there is no need to worry that the stopper 6 will slip out of the mounting groove 5 after the spoke 3 is installed.

[0031] Specifically, the cross-section of the limit block 6 and the cross-section of the installation groove 5 are both in the shape of a "convex" character, the installation groove 5 stops the lower convex edge of the limit block 6, the upper end surface of the limit block 6 exposes the protrusion 4, and the spoke 3 passes through the upper end surface of the limit block 6.

[0032] Furthermore, a convex head 9 is provided at the first end of the spoke 3, and a through hole 10 is provided on the upper end surface of the stop block 6. The spoke 3 passes through the through hole 10, and the through hole 10 limits the convex head 9 to ensure the installation of the first end of the spoke 3. In addition, the convex head 9 is sunk into the through hole 10 to avoid affecting the assembly of the stop block 6 in the installation groove 5.

[0033] In particular, the surface of the raised portion 4 passing through the spoke 3 is inclined relative to the circumferential tangential plane of the rim 1, and the inclination angle α is 20° to 30°. Each spoke 3 is arranged at a radial inclination relative to the rim 1, so that the force can be evenly transmitted between the rim 1 and the hub 2.

[0034] Furthermore, the first end of the spoke 3 has a bending portion 11, and the bending angle β of the bending portion 11 is 30° to 50° to meet the multi-angle installation requirements of the spoke 3. In this embodiment, the bending angle β is 40°.

[0035] In particular, a plurality of raised portions 4 are respectively arranged on both side edges of the circumferential inner surface of the rim 1, and a plurality of spoke caps 7 are respectively arranged on both side edges of the hub 2. The first end of each spoke 3 is limited by a limit block 6 in the raised portion 4 on one side, and the second end of the spoke 3 is fixed by the spoke cap 7 on the other side.

[0036] Preferably, the protrusions 4 on both sides are aligned one by one in the axial direction of the rim 1, and the inclined directions of the two aligned protrusions 4 are opposite to each other, so as to balance part of the acting force.

[0037] Preferably, two adjacent spokes 3 on the same side are cross-distributed to improve structural strength.

[0038] On this basis, this embodiment also provides a spoke wheel, which adopts the above-mentioned spoke installation structure.

[0039] Therefore, the spoke wheel adopting the spoke installation structure has reliable load-bearing performance and is more convenient when installing the spokes 3.

[0040] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
