Description

Technical Field

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

[0002] A wheel hub flange is a component that connects the wheel to the axle of a vehicle. It is typically a metal disc-shaped structure mounted on the outer edge of the wheel hub. The main function of the flange is to securely fasten the tire to the wheel hub with bolts or nuts, ensuring that the tire does not become loose during vehicle operation. It is usually made of high-strength aluminum alloy or steel to withstand the enormous pressure and torque generated during vehicle operation. The flange design takes into account durability, corrosion resistance, and compatibility with the wheel hub and wheel.

[0003] Currently, most existing automotive wheel hub flanges are manufactured using injection molding. While this design offers lower manufacturing costs, under high-load conditions of vibration and impact, the overall resonance is often significant, leading to cracking of the flange during long-term use. This affects its service life and safety. Furthermore, traditional wheel hub flange structures lack effective vibration control and buffering measures. During vehicle operation, vibrations are not effectively absorbed, resulting in significant vibration transmission within the system and further exacerbating component wear and fatigue.

[0004] To overcome these technical shortcomings, a design solution is needed that can effectively mitigate vibration, improve shock resistance, and enhance the overall durability of wheel hub flanges. Based on this, we propose an automotive wheel hub flange. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide an automotive wheel hub flange that can solve the problems of cracking, accelerated wear and fatigue caused by the large overall resonance and lack of effective vibration control and buffering measures in existing automotive wheel hub flanges.

[0007] To solve the above technical problems, this utility model provides an automotive wheel hub flange, which adopts the following technical solution: it includes a connecting base plate, a protective cover is installed on one side of the connecting base plate, and an anti-wear component is connected between the connecting base plate and the protective cover. The anti-wear component includes a buffer pad, and metal connecting pieces are respectively connected to both sides of the buffer pad.

[0008] The protective cover includes a wear-resistant cover plate, and a connecting shaft hole is provided through the middle of the wear-resistant cover plate, the buffer pad, and the metal connecting piece.

[0009] Optionally, the cushioning pad is made of polyurethane rubber material.

[0010] Optionally, a fixed shaft is connected to the middle of one side of the connecting base plate. The fixed shaft is matched with the connecting shaft hole structure. A first fixing hole is opened around the inner side of the fixed shaft. Several sets of positioning grooves are also opened on the inner side of the connecting base plate and the wear-resistant cover plate.

[0011] Optionally, the connecting base plate, buffer pad, metal connecting piece, and wear-resistant cover plate are all provided with second fixing holes on their outer sides, and a positioning plate is also provided on the outer side of the metal connecting piece.

[0012] Optionally, the positioning plate and the positioning groove are matched, and the positioning plate and the positioning groove are engaged by a snap-fit.

[0013] Optionally, the connecting base plate and the wear-resistant cover plate are respectively provided with several sets of buffer grooves arranged in a circular array, and each buffer groove is provided with a W-shaped reinforcing rib.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. This solution incorporates an anti-wear component between the connecting base and the protective cover. This component mainly consists of a buffer pad and a metal connecting plate. The buffer pad is made of polyurethane rubber, which has excellent tear resistance and impact resistance, effectively withstanding external impacts, compression, and tension. A positioning plate is added to the outside of the anti-wear component, and several sets of positioning grooves are opened on the inside of the connecting base and the wear-resistant cover. Because the positioning plate and the positioning grooves are interlocked, the buffer pad can be fixed and connected between the connecting base and the protective cover, ensuring that the buffer pad does not move during use and can continuously perform its shock absorption and buffering function between the connecting base and the protective cover.

[0016] 2. This solution effectively improves the strength and toughness of the connecting base plate and the wear-resistant cover plate by creating a buffer groove on the inner side of the connecting base plate and the wear-resistant cover plate, and by adding W-shaped reinforcing ribs inside the buffer groove. This design not only improves the impact resistance of the connecting base plate and the wear-resistant cover plate, but also effectively avoids cracking and damage caused by vibration. It solves the problem of large overall resonance caused by the injection molding of existing automotive wheel hub flanges, thereby avoiding cracking under vibration. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Refer to Figures 1 to 5This utility model provides an embodiment of an automotive wheel hub flange, including a connecting base plate 1, a protective cover 2 installed on one side of the connecting base plate 1, and an anti-wear component 3 connected between the connecting base plate 1 and the protective cover 2. The anti-wear component 3 includes a buffer pad 4, and metal connecting pieces 5 are respectively connected to both sides of the buffer pad 4. The protective cover 2 includes a wear-resistant cover plate 6, and a connecting shaft hole 7 is provided through the middle of the wear-resistant cover plate 6, the buffer pad 4, and the metal connecting pieces 5. By adding a buffer pad 4 between the connecting base plate 1 and the protective cover 2, the vibration generated between the connecting base plate 1 and the protective cover 2 can be buffered, the vibration frequency can be adjusted, and energy can be absorbed. By providing a buffer groove 13 and a W-shaped reinforcing rib 14 inside the connecting base plate 1 and the wear-resistant cover plate 6, the strength and toughness of the connecting base plate 1 and the wear-resistant cover plate 6 can be effectively improved. This can solve the problem that existing automotive wheel hub flanges, which are made of injection molding, have large overall resonance and are prone to cracking during use in vibration scenarios.

[0026] The buffer pad 4 is made of polyurethane rubber, which has high tear resistance and impact resistance, effectively withstanding sudden impact, compression, or tension. It buffers, regulates vibration frequency, and absorbs energy between the connecting base 1 and the protective cover 2. A fixed shaft 8 is connected to the center of one side of the connecting base 1. The fixed shaft 8 matches the structure of the connecting shaft hole 7. First fixing holes 9 are formed around the inner perimeter of the fixed shaft 8. The connecting base 1 and the wear-resistant cover 6... Several sets of positioning grooves 10 are also provided on the inner side. The positioning grooves 10 provided on the inner side of the connecting base plate 1 and the wear-resistant cover plate 6 are used for limiting the connection between the wear-resistant component 3 and the connecting base plate 1 and the protective cover 2. The connecting base plate 1, the buffer pad 4, the metal connecting piece 5 and the wear-resistant cover plate 6 are all provided with second fixing holes 11 on the outer sides. The metal connecting piece 5 is also provided with a positioning plate 12 on the outer side. The positioning plate 12 added to the outer side of the metal connecting piece 5 is used for limiting the connection between the wear-resistant component 3 and the connecting base plate 1 and the protective cover 2.

[0027] The positioning plate 12 and the positioning groove 10 are structurally matched and are engaged in a snap-fit ​​manner. Through the snap-fit ​​structure design between the positioning plate 12 and the positioning groove 10, the buffer pad 4 can be limited and connected between the connecting base plate 1 and the protective cover 2. Several sets of buffer grooves 13 are respectively opened in the interior of the connecting base plate 1 and the wear-resistant cover plate 6. W-shaped reinforcing ribs 14 are provided inside the buffer grooves 13. By opening the buffer grooves 13 in the interior of the connecting base plate 1 and the wear-resistant cover plate 6, and adding the W-shaped reinforcing ribs 14 inside the buffer grooves 13, the strength and toughness of the connecting base plate 1 and the wear-resistant cover plate 6 can be effectively improved.

[0028] Working principle: This solution uses an anti-wear component 3 installed between the connecting base plate 1 and the protective cover 2. This anti-wear component 3 mainly consists of a buffer pad 4 and a metal connecting piece 5. The anti-wear component 3 uses a positioning plate 12 installed on the outside and several sets of positioning grooves 10 opened on the inside of the connecting base plate 1 and the wear-resistant cover plate 6. Because the positioning plate 12 and the positioning grooves 10 are in a snap-fit ​​fit, the buffer pad 4 can be limited and connected between the connecting base plate 1 and the protective cover 2. The buffer pad 4 is made of polyurethane rubber, which has high tear resistance and... It has high impact resistance and can effectively withstand sudden impact, compression or tension. It can buffer, regulate vibration frequency and absorb energy for vibrations generated between the connecting base plate 1 and the protective cover 2. With the buffer grooves 13 opened in the connecting base plate 1 and the wear-resistant cover plate 6 respectively, and the W-shaped reinforcing ribs 14 installed in the buffer grooves 13, it can effectively improve the strength and toughness of the connecting base plate 1 and the wear-resistant cover plate 6. It can solve the problem that the existing automobile wheel hub flanges are made of injection molding and have large overall resonance during use in vibration scenarios, which leads to cracking.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
