Description

Technical Field

[0001] This utility model relates to the field of wheel hub technology, and in particular to an aluminum alloy Kaba wheel hub. Background Technology

[0002] A wheel rim is a cylindrical metal component mounted on an axle, supporting the tire's inner contour. It is also called a steel rim, wheel wheel, or tire rim. Wheel rims come in many varieties depending on their diameter, width, forming method, and material. In recent years, with the increasing stringency of national regulations on overloading and exceeding size limits in the truck and bus market, users have become more inclined towards lightweight products, and their requirements for purchased vehicles have changed significantly. Therefore, the market share of aluminum alloy wheel rims is increasing.

[0003] In the existing technology, the valve stem hole on the aluminum alloy Kaba (truck, bus) wheel hub generally overlaps with the air vent, which causes stress concentration around the valve stem hole and is prone to cracking, affecting the safety performance of the aluminum alloy Kaba wheel hub. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum alloy Kaba wheel hub, in which the valve stem hole is located in the recessed part at the junction of the spoke and the rim, and the valve stem hole is staggered from the air hole, which is conducive to stress dispersion and avoids the common situation of cracks caused by the overlapping position of the valve stem hole and the air hole, thereby improving the safety performance of the aluminum alloy Kaba wheel hub and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An aluminum alloy Kaba wheel hub includes a rim and spokes; the spokes are connected to the upper part of one end of the rim, and several air holes are provided on the spokes. One end of the spokes is a mounting surface, and a central positioning hole is located at the center of the mounting surface, and several mounting holes are provided on the mounting surface; a valve stem hole is provided in the recessed part at the joint between the spokes and the rim, and the valve stem hole is offset from the air holes.

[0007] A further improvement of this invention is that the cross-sectional thickness of the spokes is smaller than that of the rim.

[0008] A further improvement of this utility model is that the spokes and rim are integrally formed by casting.

[0009] A further improvement of this utility model is that the rim is integrally formed by a spinning process.

[0010] A further improvement of this utility model is that the outer end of the spoke protrudes from one end of the rim.

[0011] A further improvement of this invention is that the air holes are distributed in a ring array on the wheel spokes.

[0012] A further improvement of this utility model is that the valve stem hole is located at the center of two of the air holes.

[0013] The beneficial effects of this utility model are:

[0014] The aluminum alloy Kaba wheel hub of this utility model has a valve stem hole located in the recessed part at the junction of the spoke and the rim, and the valve stem hole is staggered from the air hole, which is conducive to stress dispersion and avoids the common situation of cracks caused by the overlapping of the valve stem hole and the air hole, thus improving the safety performance of the aluminum alloy Kaba wheel hub.

[0015] The aluminum alloy Kaba wheel hub of this utility model, through casting and spinning processes, makes the cross-sectional thickness of the spokes smaller than that of the rim, resulting in a denser internal metallographic structure, better mechanical properties, a thinner cross-section, and lighter weight.

[0016] The aluminum alloy Kaba wheel hub of this utility model has the outer end of the spoke protruding from one end of the rim, which ensures better heat dissipation of the wheel hub. Attached Figure Description

[0022] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: As Figs. 1-4 As shown, an aluminum alloy Kaba wheel hub includes a rim 1 and spokes 2; the spokes 2 are connected to the upper part of one end of the rim 1, and the spokes 2 are provided with several air holes 3. One end of the spokes 2 is a mounting surface 4, the center of the mounting surface 4 is a central positioning hole 5, and the mounting surface 4 is provided with several mounting holes 6; the recessed part at the joint between the spokes 2 and the rim 1 is provided with a valve stem hole 7, and the valve stem hole 7 is offset from the air holes 3.

[0024] The cross-sectional thickness of spoke 2 is smaller than that of rim 1.

[0025] The spokes 2 and the rim 1 are integrally formed by casting.

[0026] The rim 1 is integrally formed by spinning process.

[0027] The outer end of the spoke 2 protrudes from one end of the rim 1.

[0028] The air holes 3 are arranged in a ring array on the spokes 2.

[0029] The center of valve stem hole 7 and two of the air holes 3.

[0030] The valve stem hole 7 of this invention is located in the recessed part at the junction of the spoke 2 and the rim 1, and the valve stem hole 7 is staggered from the air hole 3, which is conducive to stress dispersion and avoids the common situation of cracks caused by the overlapping positions of the valve stem hole 7 and the air hole 3, thus improving the safety performance of the aluminum alloy Kaba wheel hub. Through casting and spinning processes, the cross-sectional thickness of the spoke 2 is smaller than that of the rim 1, resulting in a denser metallographic structure inside the wheel hub, better mechanical properties, a thinner cross-section, and lighter weight. In addition, the outer end of the spoke 2 protrudes from one end of the rim 1, ensuring better heat dissipation of the wheel hub.
