Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a lightweight and high-strength wheel hub. Background Technology

[0002] With the implementation of energy conservation, emission reduction, and "slimming down" measures in the automotive market, the lightweighting of the whole vehicle and the lightweighting of parts have become important indicators for the whole vehicle and major component assemblies. Furthermore, with the promotion of new energy vehicles, the lightweighting of automotive parts is particularly important, among which the lightweighting of automotive wheels makes a significant contribution to energy conservation and emission reduction in vehicle body lightweighting.

[0003] Existing car wheel rims are relatively easy to damage when they collide with objects, which may require the replacement of the entire wheel rim. If more alloy materials are used to make car wheel rims, the weight of the rim will be greater, thereby increasing fuel consumption. Utility Model Content

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0021] This embodiment mainly describes a lightweight and high-strength wheel hub, as detailed below:

[0022] like Figures 1-4 As shown, a lightweight and high-strength wheel hub includes a first wheel hub 2 and a second wheel hub 4, which are detachably connected together. Specifically, one end of the first wheel hub 2 is provided with a first protrusion 13, which extends into the interior of the first wheel hub 2; one end of the second wheel hub 4 is provided with a second protrusion 14, which extends into the interior of the second wheel hub 4. Both the first protrusion 13 and the second protrusion 14 are provided with screw holes 9 for connection and fixing, and the screw holes 9 on the first protrusion 13 and the second protrusion 14 are corresponding to each other. When the first wheel hub 2 and the second wheel hub 4 are connected together, the first protrusion 13 and the second protrusion 14 are close to each other, and the first wheel hub 2 and the second wheel hub 4 are fixedly connected by bolts passing through the screw holes 9.

[0023] When the first wheel hub 2 or the second wheel hub 4 needs to be replaced, only the corresponding wheel hub needs to be replaced, instead of replacing the entire wheel hub, thus reducing maintenance costs.

[0024] like Figure 1 , Figure 3 As shown, the first hub 2 is provided with five outer spokes 3. The five outer spokes 3 are evenly distributed on the first hub 2. One end of the outer spoke 3 is fixed on the first hub 2, and a reinforcing rib 1 is provided at the connection between the outer spoke 3 and the first hub 2. The reinforcing rib 1 increases the contact area between the outer spoke 3 and the first hub 2 and enhances the deformation resistance of the outer spoke 3.

[0025] A connecting shaft 10 is provided inside the first hub 2, and the other end of the outer spoke 3 is fixedly mounted on the connecting shaft 10.

[0026] like Figure 2 As shown, each outer spoke 3 has a groove 11 on its inner side to reduce the overall weight of the first hub 2.

[0027] like Figure 3 , Figure 4 As shown, an inner spoke 6 is fixedly provided inside the second hub 4. Specifically, a connecting part 5 is provided on the inner spoke 6. The connecting part 5 is fixedly provided around the inner spoke 6. The connecting part 5 is provided with screw holes 9 corresponding to the first protrusion 13 and the second protrusion 14. The connecting part 5 is abutted against the second protrusion 14 and is fixed to the connecting part 5 by bolts passing through the first protrusion 13 and the second protrusion 14 at the same time.

[0028] Furthermore, a mounting base 7 is provided at the center of the inner spoke 6. Several locking blocks 8 extending inward are provided on the mounting base 7. Specifically, there are five locking blocks 8, which are evenly distributed on the inner side of the mounting base 7. The connecting shaft 10 is provided with a slot 12 corresponding to the number of locking blocks 8. The slot 12 is strip-shaped and is provided on the surface of the connecting shaft 10 along the axial direction of the connecting shaft 10. When the user installs the inner spoke 6, the locking blocks 8 are aligned with the slot 12, so that the inner spoke 6 slides in the slot 12 through the locking blocks 8. When the connecting part 5 is close to the second protrusion 14, the locking blocks 8 are engaged in the slot 12, limiting the rotation of the inner spoke 6 in the axial direction of the connecting shaft 10, so that the connection between the inner spoke 6 and the second protrusion 14 is more stable.

[0029] The cross-sectional thickness of the locking block 8 is the same as that of the mounting base 7, and the cross-sectional thickness of the mounting base 7 is greater than that of the inner spoke 6, so as to enhance the connection stability between the inner spoke 6 and the mounting base 7 and the compressive strength of the mounting base 7.

[0030] The inclusion of six inner spokes enhances the overall compressive strength of the wheel hub and extends its service life.
