Description

Technical Field

[0001] This utility model relates to the field of vehicle wheel hub technology, specifically a lightweight wheel hub structure. Background Technology

[0002] The wheel hub is one of the core components of a vehicle wheel, responsible for bearing the weight of the tire and transmitting the vehicle's power, braking, and steering forces to the ground. The wheel hub is not only crucial for bearing weight but also plays a significant role in the vehicle's performance, safety, and appearance. It must withstand loads from the ground and the vehicle, including the vehicle's own weight, loads, and kinetic energy and braking forces generated during driving. The wheel hub must ensure a secure connection between the tire and the axle while effectively distributing stress from the ground, braking, and steering. The wheel hub secures the tire by mating with it, ensuring it doesn't detach at high speeds. The wheel rim provides the foundation for a tire seal, preventing air pressure leakage.

[0003] Common wheel materials include aluminum alloy, steel, magnesium alloy, titanium alloy, and carbon fiber. The manufacturing process of a wheel directly affects its strength, weight, and production cost. Common wheel manufacturing processes include casting, forging, die casting, and extrusion molding.

[0004] The structure of a vehicle wheel hub typically consists of a hub center, spokes, rim, bolt holes, and safety edge. Compared to heavier wheels, lightweight wheels offer advantages such as improved fuel economy, enhanced acceleration, improved handling, improved braking performance, increased suspension efficiency, and reduced tire wear. Therefore, while maintaining the same material and strength, it is necessary to reduce the amount of material used in the wheel hub to achieve this goal. However, most existing wheel hubs are designed with spokes in mind, reducing the amount of spoke material to reduce the hub's weight. The applicant, while ensuring the hub's strength, further reduced the hub's weight by decreasing the amount of material used in the hub center. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 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.

[0023] Please see Figure 1-4 This embodiment provides a lightweight wheel hub structure, including a support ring 1 and a center disc 2. The support ring 1 is the rim of the wheel hub, the part that directly contacts the tire, supporting the tire and ensuring a tight fit between the tire and the wheel hub. The support ring 1 has a flat cylindrical shape at its center, with safety edges and reinforcing ribs at both ends to enhance strength and resistance to detachment, preventing the tire from detaching under low air pressure or flying off at high speed. The center disc 2 is the hub center of the wheel hub, used for connection to the vehicle axle.

[0024] The center disc 2 is located inside the support ring 1, and multiple first spokes 3 connect the center disc 2 and the support ring 1. The first spokes 3 support the center disc 2, ensuring that the center disc 2 is positioned within the central axis of the support ring 1. During vehicle operation, the first spokes 3 also share the load of the wheel hub and provide support and force transmission. The support ring 1, center disc 2, and first spokes 3 are made of carbon fiber. Compared to other wheel hub materials (such as steel, aluminum alloy, and titanium alloy), carbon fiber wheels are lighter and have higher rigidity without changing the structure. The support ring 1, center disc 2, and first spokes 3 are all integrally molded in the same mold. This integral molding improves impact resistance, making the wheel hub less prone to deformation, cracking, or breakage when the vehicle is traveling at high speed or subjected to severe impacts, thus improving safety. The integral molding mold can complete the main structure of the wheel hub in one molding process, avoiding dimensional errors caused by multiple processing steps and improving precision.

[0025] Since reducing wheel hub weight has advantages such as improving fuel economy, enhancing acceleration performance, improving handling performance, enhancing braking performance, improving suspension system efficiency, and reducing tire wear, in order to further reduce the wheel hub weight of this utility model, the center disc 2 includes a center cylinder 21, a fixed cylinder 22, and a second spoke 23. Since most vehicle axles have five axle bolts for connection, the fixed cylinder 22 is set to five. Of course, the fixed cylinder 22 is not limited to five; it can be selected according to the number of axle bolts connecting the vehicle. Figure 2 and Figure 4As shown, the central cylinder 21 is located at the inner center of the support ring 1, and five fixed cylinders 22 are evenly arranged in a circular array around the central cylinder 21 with the central axis of the support ring 1 as the center. The two ends of the second spoke 23 are connected to the central cylinder 21 and the fixed cylinders 22 respectively, and are used to fix the position between the central cylinder 21 and the fixed cylinders 22.

[0026] The center cylinder 21 has a center hole through which it connects to the axle, serving as the fixing point between the wheel hub and the vehicle. The fixing cylinder 22 has bolt holes for fixing the wheel hub to the axle or connecting it to the wheel bolts (the axle bolts pass through the bolt holes, and the protruding axle bolts are then connected by a nut threaded through them). The wheel is fixed to the vehicle's suspension system through these holes.

[0027] like Figure 1 and Figure 3 As shown, the two first spokes 3, which are symmetrical and form a V-shaped structure, are a set of support bars, and each fixed cylinder 22 is connected to a set of support bars. The support bars and support ring 1 form a fan-shaped structure (quasi-triangular structure). The V-shaped spoke structure can effectively distribute the force on the wheel hub, especially the impact force during high-speed driving or braking. Due to the V-shaped connection of the spokes, the force distribution at the stress points can be more uniform, enhancing the overall strength and rigidity of the wheel hub.

[0028] like Figure 2 and Figure 4 As shown, the two second spokes 23, which are symmetrical and form a figure-eight structure, are a set of connecting strips, and each fixed cylinder 22 is connected to a set of connecting strips. In order to increase the structural strength of the central disc 2, as shown... Figure 1 and Figure 2 As shown, the first spoke 3 on the fixed cylinder 22 and the second spoke 23 installed on the other side of the same fixed cylinder 22 are located on the same plane. Therefore, when the vehicle is in use, the pressure transmitted from the support ring 1 to the first spoke 3 will be transmitted to the second spoke 23 through the fixed cylinder 22, and finally to the center cylinder 21. The stable transmission of the wheel hub pressure ensures the stability of the wheel hub structure.

[0029] Compared to existing disc-shaped wheel hubs, the center disc 2 of this invention consists of a center cylinder 21, a fixed cylinder 22, and a second spoke 23, forming a hollow structure. While maintaining the same material and strength, this design further reduces the overall weight of the wheel hub, resulting in a lighter design. This lighter wheel hub reduces the overall weight of the vehicle. With reduced vehicle weight, the engine needs to consume less energy to drive the vehicle, thus improving fuel efficiency. In daily driving, reducing wheel weight effectively reduces fuel consumption, especially during long-distance city driving or high-speed driving, where this advantage is particularly significant. The lightweight wheel hub also reduces the wheel's moment of inertia, allowing for faster acceleration. Reduced wheel inertia means the engine needs to overcome less friction, resulting in more rapid acceleration. Reduced inertia allows the vehicle to more efficiently convert engine power into wheel rotation, leading to faster acceleration, especially noticeable during start-up and high-speed driving. The lighter wheel hub also reduces wheel mass, making the vehicle more agile and precise in cornering. This is especially important for sports sedans and race cars, providing better steering response and handling. Reduced wheel weight reduces the load on the suspension system when cornering or under stress, allowing for more precise suspension adjustments and improved driving stability. Lightweight wheels reduce the weight of the wheels, thus reducing the burden on the braking system. For the braking system, lighter wheels allow braking force to be transmitted to the wheels more quickly, shortening braking distance and improving braking response. Reduced wheel weight also reduces heat buildup during braking, preventing overheating and brake fade, and improving braking system stability. Lightweight wheels allow the suspension system to more effectively handle impacts from uneven road surfaces because the lighter wheels result in a more responsive suspension. This improved responsiveness, especially when traversing potholes or at high speeds, enhances vehicle comfort and stability. Lighter wheels exert less impact on the tires, helping to extend tire life. By reducing tire-road friction and vibration, tire wear becomes more even, improving tire durability.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
