Description

Technical Field

[0001] This utility model relates to the technical field of ribbed wheel hub assemblies, and in particular to a split-type ribbed wheel hub assembly. Background Technology

[0002] The wheel hub is a key component for vehicle load-bearing and transmission, and its performance is crucial. Modern wheel hub designs, especially in applications emphasizing high performance and lightweight construction, typically incorporate additional plate-like ribs (or reinforcing ribs) on the front or back of the wheel hub body (including the center ring, spokes, and rim). These ribs are not the spokes that provide primary support, but rather serve to improve the local rigidity of the wheel hub, enhance resistance to torsional deformation, optimize heat dissipation, and improve aerodynamics.

[0003] In existing technologies, the ribs are mostly manufactured as a single piece with the wheel hub body. This one-piece structure has the following main drawbacks:

[0004] First, the manufacturing process is complex and costly. For wheel hubs with complex rib shapes, one-piece molding requires the design and manufacture of complex molds, which makes the production process difficult and results in a low yield rate. This is especially true when the ribs are small or have special curved surfaces, which can easily lead to casting defects and increase manufacturing costs.

[0005] Secondly, repair and replacement are extremely inconvenient and uneconomical. During long-term use, the protruding ribs of the wheel hub are highly susceptible to damage from scratches and impacts. Since the ribs are an integral part of the wheel hub, any localized damage can render the entire wheel assembly unusable, forcing users to pay exorbitant costs to replace the entire hub, resulting in unnecessary waste.

[0006] Third, the limited material selection restricts performance optimization. The unibody structure dictates that the wheel hub body and the ribs must use the same material, making it impossible to differentiate the optimal material based on the different stress characteristics of each part (such as the center ring requiring high rigidity and the ribs requiring high tensile strength), thus limiting further improvements in the overall performance of the wheel hub.

[0007] Fourth, personalized customization is difficult. The one-piece structure prevents users from changing the color or style of the ribs according to personal preferences or specific needs, resulting in insufficient product flexibility and fun.

[0008] Therefore, there is an urgent need in this field for a new wheel hub rib structure solution to solve the many problems caused by the aforementioned integrated structure. Utility Model Content

[0009] The purpose of this utility model is to provide a split-type ribbed wheel hub assembly to overcome the shortcomings of the prior art.

[0010] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0011] A split-type ribbed wheel hub assembly includes a wheel hub body, the center of which is provided with a central ring, and the outer contour has a plurality of protruding bosses distributed at equal intervals. It also includes split-type plate-shaped ribs with the same number of bosses. One end of each plate-shaped rib is detachably connected to the central ring by a first fastener, and the other end is detachably connected to the corresponding boss by a second fastener.

[0012] Further improvements to optimize the technical solution include:

[0013] The number of the aforementioned bosses is six, and correspondingly, the number of the plate-shaped reinforcing bars is also six.

[0014] An annular central ring mounting portion is integrally formed on the outer peripheral wall of the aforementioned central ring, and the central ring mounting portion is fixedly connected to one end of the plate-shaped rib by a first fastener.

[0015] The aforementioned boss includes a boss seat and a boss cover. The boss seat is provided with a boss cavity. The other end of the plate-shaped rib passes through the boss seat and extends into the boss cavity. The boss cover can cover the boss seat to close the boss cavity. At the same time, the boss cover is fixedly connected to the other end of the plate-shaped rib by a second fastener.

[0016] Mounting holes are provided at both ends of the aforementioned plate-shaped rib, the central ring mounting part, and the boss cover. The first fastener is inserted into the mounting holes of one end of the plate-shaped rib and the central ring mounting part to achieve a detachable connection between the plate-shaped rib and the central ring mounting part. The second fastener is inserted into the mounting holes of the other end of the plate-shaped rib and the boss cover to achieve a detachable connection between the plate-shaped rib and the boss.

[0017] The first and second fasteners mentioned above are screws or bolts.

[0018] The aforementioned plate-shaped reinforcing bars are made of aluminum alloy, carbon fiber composite material, or magnesium alloy.

[0019] The structure and dimensions of each of the plate-shaped reinforcing bars are exactly the same.

[0020] The surface of the aforementioned plate-shaped reinforcing bars is provided with weight-reducing holes.

[0021] The technical advantages of this utility model are as follows:

[0022] 1. This utility model greatly simplifies the casting mold structure and process complexity of the wheel hub body by designing the ribs and wheel hub body as separate structures. The ribs can be produced as separate standard parts, and their production process is easier to control. This effectively avoids defects such as incomplete filling and porosity that are prone to occur in the rib area in traditional one-piece casting, thereby significantly improving the production yield and reducing the overall manufacturing cost.

[0023] 2. Because the ribs are detachably connected to the center ring and boss via fasteners, when a rib is damaged due to scratches or collisions, the damaged rib can be replaced individually simply by unscrewing the fasteners, without having to scrap the entire wheel assembly. This completely solves the drawback of the traditional unibody structure of "partial damage, overall scrapping," saving users high replacement costs and conforming to the concepts of green environmental protection and sustainable use.

[0024] 3. The split design breaks the limitations of material selection. The wheel hub body and plate-shaped ribs can be made of the most suitable materials according to their different stress characteristics and performance requirements. This material combination strategy of "taking the best from each" can maximize the overall performance of the wheel hub assembly.

[0025] 4. By inserting the ends of the reinforcing ribs into the boss cavity and securing them with the boss cover, and by using multiple fasteners for connection, a robust mechanical connection structure is formed. This connection method avoids the heat-affected zone and stress concentration problems caused by welding, ensuring the strength and fatigue resistance of the connection points, and guaranteeing the safety and reliability of the product.

[0026] 5. Users can easily change the ribs to different colors, surface finishes, or styles to meet their individual aesthetic needs. This transforms the wheel hub from a static functional component into a dynamic, modular product that can be customized, enhancing its appeal and market attractiveness. Attached Figure Description

[0033] See Figures 1 to 3 The present invention relates to a split-type ribbed wheel hub assembly, which mainly includes a wheel hub body 1, plate-shaped ribs 2, a first fastener 3, and a second fastener 4.

[0034] The wheel hub body 1 is integrally formed from aluminum alloy through a casting process. Its structure includes a central ring 11, an outer contour, and multiple spokes connecting the central ring 11 and the outer contour. The outer contour has six protruding bosses 12 that are evenly spaced.

[0035] A ring-shaped mounting portion 111 is integrally cast on the outer peripheral wall of the central ring 11. Six sets of threaded holes are uniformly machined along the circumference of the central ring mounting portion 111.

[0036] The boss 12 is a hollow structure, consisting of a boss seat 121 and a boss cover 122. The boss seat 121 is integrally formed with the outer contour of the wheel hub body 1, and has a boss cavity 123 inside. The boss cover 122 can be engaged with the second fastener 4 through its hole to cover the boss seat 121, thereby sealing the boss cavity 123.

[0037] There are six plate-shaped ribs 2, each corresponding to one of the bosses 12. In this embodiment, the plate-shaped ribs 2 are molded from carbon fiber composite material, which has the advantages of being lightweight and high-strength. Each plate-shaped rib 2 has a beautiful arc-shaped aerodynamic shape along its length. Mounting holes are opened at both ends of the plate-shaped ribs 2. To further achieve lightweighting, multiple weight-reduction holes 21 are also stamped on the surface of the plate-shaped ribs 2.

[0038] In this embodiment, both the first fastener 3 and the second fastener 4 are stainless steel bolts with internal hexagonal head caps.

[0039] The assembly process is as follows:

[0040] Place one end of a single plate-shaped rib 2 facing the center ring 11 against the corresponding position of the center ring mounting part 111, so that the mounting hole on it is aligned with the threaded hole on the center ring mounting part 111.

[0041] The first fastener 3 is passed through the mounting hole at one end of the plate-shaped rib 2 and screwed into the threaded hole of the center ring mounting part 111. It is tightened with a preset torque to reliably fix that end of the plate-shaped rib 2 to the center ring 11.

[0042] The plate-shaped reinforcing bar 2 is inserted into the boss cavity 123 of the corresponding boss 12 at the other end facing the boss 12.

[0043] The boss cover 122 is placed on the boss seat 121, at which point the hole on the boss cover 122 and the mounting hole at the other end of the plate-shaped rib 2 are aligned.

[0044] Use a second fastener 4 to pass through the hole in the boss cover 122 and the mounting hole in the plate rib 2 in sequence and tighten it.

[0045] Repeat the above steps to install the remaining five plate-shaped reinforcing bars 2 in sequence.

[0046] This utility model, by designing the rib and the wheel hub body as separate parts and connecting them with mechanical fasteners, brings the following advantages:

[0047] In terms of production: the mold structure of the wheel hub body 1 has been simplified, improving the yield rate. The plate-shaped ribs 2 can be mass-produced separately as standard parts, resulting in lower costs and more controllable quality.

[0048] In terms of maintenance: If a scratch on the vehicle damages a plate-shaped rib 2, the damaged rib can be replaced individually by simply unscrewing the fasteners at both ends, without having to replace the entire expensive wheel assembly, thus greatly reducing maintenance costs.

[0049] In terms of performance: the wheel hub body 1 can be made of high-toughness aluminum alloy casting, while the plate-shaped ribs 2 can be made of high-strength carbon fiber material, achieving the optimal combination of materials and improving the overall performance of the product.

[0050] In terms of personalization: users can purchase different colors or surface textures of the plate-shaped ribs 2 according to their preferences for easy replacement, thus meeting their personalized needs.

[0051] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
