Description

Technical Field

[0001] This utility model relates to a high-strength aluminum alloy wheel hub structure, and more particularly, to a high-strength aluminum alloy wheel hub structure. Background Technology

[0002] In existing designs, the structure of aluminum alloy wheel hubs is similar to that of the applicant's earlier utility model patent CN219947767U, which describes a deformation-resistant aluminum alloy wheel hub. Its main structure includes a wheel hub body and a bushing. Several support plates are connected between the wheel hub body and the bushing. A brake disc seat is connected to the reverse side of the bushing. The brake disc seat has five fixed protrusions, each with a groove. These fixed protrusions are mainly used to provide the mounting position for the brake disc.

[0003] The aforementioned aluminum alloy wheels have excellent deformation resistance and are widely recognized in the market. However, in practical applications, these types of wheels are only compatible with brake discs that have a single circumferential array of mounting holes. Some brake disc structures that require higher connection stability to meet the needs of aggressive driving have an outer disc body and an inner connecting disc body. The inner connecting disc body is located inside the outer disc body. The outer disc body has multiple first mounting holes distributed in a circumferential array, and the inner connecting disc body also has multiple second mounting holes distributed in a circumferential array. In this case, the existing wheel structure cannot be stably connected with this type of brake disc and urgently needs further improvement. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a high-strength aluminum alloy wheel hub structure that can meet higher connection strength requirements.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A high-strength aluminum alloy wheel hub structure includes a rim, spokes, and a disc mounting base. The disc mounting base is located in the middle of the rim. The spokes connect the rim and the disc mounting base. The disc mounting base has a plurality of first fixing protrusions. A plurality of connecting blocks are integrally formed around the periphery of the disc mounting base. The spokes connect the connecting blocks and the rim. Each connecting block has a second fixing protrusion. The protrusion direction of the first fixing protrusion is consistent with the protrusion direction of the second fixing protrusion.

[0006] Through the above technical solution, the outer disc of the brake disc can be attached to the first fixed protrusion, and the inner connecting disc of the brake disc can be attached to the second fixed protrusion. Bolts pass through the outer disc and are threaded onto the first fixed protrusion, and bolts pass through the inner connecting disc and are threaded onto the second inner connecting disc. At this time, not only are the effective connection points between the entire brake disc and the wheel hub greatly increased, but the first and second fixed protrusions on the wheel hub also provide the brake disc with sufficiently strong support and stability, which can meet the connection stability requirements under intense driving conditions, and the operational reliability is also effectively enhanced.

[0007] Preferably, the spokes include a plurality of spoke assemblies, and the plurality of spoke assemblies correspond one-to-one with a plurality of connecting blocks. The spoke assembly includes a central spoke and two side spokes, and the two side spokes are symmetrically distributed on both sides of the central spoke.

[0008] Through the above technical solution, the three spokes can provide a single connecting block with sufficiently strong connection stability.

[0009] Preferably, the side spokes on the spoke assembly between two adjacent connecting blocks intersect each other.

[0010] The above technical solution enables the two connecting blocks to work together to enhance connection stability, thereby further improving structural strength.

[0011] Preferably, the protrusion height of the first fixing protrusion is higher than that of the second fixing protrusion.

[0012] The above technical solution can, on the one hand, adapt to the installation requirements of outer discs and inner connecting discs with height differences; on the other hand, it can also save some of the materials used in the casting process.

[0013] Preferably, the first fixed protrusion, the second fixed protrusion, and the connecting block are connected by reinforcing ribs.

[0014] The above technical solution improves the connection strength between the first fixed protrusion, the second fixed protrusion, and the connecting block, resulting in higher overall structural strength during use.

[0015] Preferably, the mounting base of the disc body is provided with a hollow groove.

[0016] The above technical solutions can effectively reduce the overall weight of the disk mounting base, thus meeting the requirements for lightweight design.

[0017] Preferably, the first fixed protrusion is provided with a weight-reducing groove, and the weight-reducing groove is connected to the hollow groove.

[0018] Through the above technical solution, on the one hand, since the traditional solid protruding column structure also requires drilling and tapping processing, a weight reduction groove is set in the protruding column during the casting process, which can reduce the overall weight of the first fixed protruding column, reduce material costs, and make subsequent processing more convenient; on the other hand, the weight reduction groove is connected to the hollow groove, and the molten aluminum liquid in the molten state can more easily flow into the corresponding space.

[0019] Preferably, the weight-reducing groove is provided with a plurality of connecting pieces, which are arranged in a circular array around the axis of the first fixed protrusion, with two adjacent connecting pieces spaced apart from each other.

[0020] The above technical solution achieves several advantages. First, by using several connecting pieces instead of solid casting of the sidewalls, casting costs are saved. Second, during subsequent processing, only drilling and tapping of the sidewalls formed by the connecting pieces are required for subsequent use, making processing more convenient.

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 The specific embodiments of this utility model will be further described in detail to make the technical solution of this utility model easier to understand and master.

[0024] A high-strength aluminum alloy wheel hub structure includes a rim 1, spokes 2, and a disc mounting base 3. The disc mounting base 3 is located in the middle of the rim 1, and the spokes 2 connect the rim 1 and the disc mounting base 3.

[0025] The mounting base 3 of the disk has several integrally formed connecting blocks 5 around its perimeter. In this embodiment, there are 6 connecting blocks 5.

[0026] The spoke 2 connects the connecting block 5 to the rim 1. The spoke 2 includes several spoke assemblies 21, each corresponding to one of the connecting blocks 5. Each spoke assembly 21 includes one central spoke 211 and two side spokes 212, symmetrically distributed on both sides of the central spoke 211. The side spokes 212 on the spoke assembly 21 between two adjacent connecting blocks 5 intersect each other.

[0027] The mounting base 3 of the disk is provided with a number of first fixing protrusions 4. In this embodiment, the number of first fixing protrusions 4 is 6.

[0028] Each connecting block 5 is provided with a second fixing protrusion 6, and the protrusion direction of the first fixing protrusion 4 is the same as the protrusion direction of the second fixing protrusion 6. The protrusion height of the first fixing protrusion 4 is higher than the protrusion height of the second fixing protrusion 6.

[0029] The first fixed protrusion 4, the second fixed protrusion 6, and the connecting block 5 are connected by reinforcing ribs 7.

[0030] A hollow groove 8 is provided inside the mounting base 3 of the disc body. A weight-reducing groove 9 is provided inside the first fixed protrusion 4, and the weight-reducing groove 9 is interconnected with the hollow groove 8. A plurality of connecting pieces 10 are provided inside the weight-reducing groove 9. In this embodiment, the number of connecting pieces 10 is 3 pieces, and the 3 connecting pieces 10 are arranged in a circular array with the axis of the first fixed protrusion 4 as the center, and the two adjacent connecting pieces 10 are spaced apart from each other.

[0031] See Figure 4 Using this diagram as a reference, the wheel hub will subsequently require drilling and tapping of the right end face of the first fixed protrusion 4 and the right end face of the second fixed protrusion 6. In particular, for the first fixed protrusion 4, the drilling bit will be inserted into the first fixed protrusion 4 from right to left, and the tapping bit will tap the right end of the first fixed protrusion 4 and the inner wall of the connecting piece 10 in sequence to form an internal thread hole. Subsequently, the brake disc can be placed against the right end face of the first fixed protrusion 4, and the bolt will pass through the brake disc from right to left and be threaded onto the right end of the first fixed protrusion 4 and the connecting piece 10.
