[0001] INNOVATIVE WHEEL DESIGN WITH MODIFIED AERODYNAMICS FOR THE BRAKE SYSTEM

[0002] TECHNICAL FIELD

[0003] The invention relates to a wheel for use in vehicles, comprising at least one rim for mounting a tire thereon and at least one disc for mounting the said rim onto a disc flat surface.

[0004] PRIOR ART

[0005] Brake cooling systems used around vehicle wheels have been developed to prevent excessive heating of the brakes and to improve braking performance. Excessive heating of the brakes reduces braking performance and can shorten the lifespan of brake components. Therefore, brake cooling systems are of great importance. The most common brake cooling systems include air ducts and fins, perforations and grooves on brake discs, and liquid cooling systems. Air ducts and fins enhance airflow around the brake discs, facilitating heat dissipation. Perforations and grooves on the brake discs help dissipate heat more quickly during braking and assist in expelling gases and dust from the brake pads. Liquid cooling systems, which are used in high-performance and heavy-duty vehicles, transfer heat by circulating coolant within the brake calipers or discs.

[0006] Wheels have a significant impact on brake cooling systems. The design and material of the wheels can aid in cooling the brakes. Wheels made from lightweight materials with high thermal conductivity allow heat from the brake discs to dissipate more quickly. An open-wheel structure enhances airflow, helping to dissipate heat from the brake discs more efficiently. Additionally, air holes and channels on the wheel optimize airflow, improving brake cooling. Larger wheels provide a greater surface area, enhancing heat dissipation and allowing for larger brake discs, which further improve cooling performance. The known application CN214874749 in the literature describes a wheel structure consisting of a wheel, with a wheel spoke placed on the inner side surface near the front section of the rim, where the rim and the wheel spoke are fixed by welding. The structure includes distributed air holes and air holes with height differences. Inadequate cooling of the brakes can significantly reduce braking performance, posing a risk to driving safety. Overheated brake discs and pads may become less effective during braking, leading to an extended braking distance. Additionally, high temperatures can cause premature wear of brake pads and discs, increasing maintenance costs and shortening the lifespan of the braking system.

[0007] Inadequate cooling can lead to a condition known as "brake fading." Brake fading is the reduction of braking force due to excessive heating of the brakes. This situation can be particularly dangerous during downhill driving, where prolonged and intense braking is required. Additionally, continuous exposure of brake components to high temperatures can cause the brake fluid to reach its boiling point, leading to the formation of air bubbles in the brake hydraulic system. This results in a softening of the brake pedal and a decrease in braking force.

[0008] Insufficient performance of the wheels affects not only braking performance but also overall vehicle performance and safety. Overheated brakes can also cause the tires and suspension components to heat up. This may reduce tire grip and negatively impact the performance of the suspension system. Additionally, excessive heat can lead to deformation of the brake discs and wheels, resulting in vibrations and a decrease in driving comfort.

[0009] As a result, all the above-mentioned problems have made it imperative to make an innovation in the relevant technical field.

[0010] SUMMARY OF THE INVENTION

[0011] The present invention relates to a wheel for eliminating the above-mentioned disadvantages and bringing the new advantages to the relevant technical field. An object of the invention is to provide a rim with improved brake cooling properties in vehicles.

[0012] In order to achieve all the purposes mentioned above and that will emerge from the detailed description below, the present invention is related to, a wheel for use in vehicles, comprising at least one rim for mounting a tire thereon and at least one disc for mounting the said rim onto a disc flat surface. Accordingly, its novelty is that, the disc comprises at least one disc body that is rounded around the inner wall of the rim and at least one disc opening at its center, wherein the disc body has a quarter circle form such that one side is welded to the rim and the other side is mounted onto the disc flat surface, wherein the disc body includes at least one cooling hole to allow air transfer to the braking system, and wherein the disc body further comprises at least one formed section in a convex structure that at least partially protrudes outward from the disc body to allow air intake into the cooling hole.

[0013] A possible embodiment of the invention is characterized in that, disc body comprises at least one non-formed section. Thus, the non-formed section maintains the continuity of the rounded form of the disc body, helping to regulate airflow and allowing air to enter the cooling holes more efficiently.

[0014] Another possible embodiment of the invention is characterized in that, multiple cooling holes, formed sections, and non-formed sections are arranged sequentially side by side along the disc body. Thus, heat is more effectively dissipated across the disc during braking, preventing excessive heating of the brake discs, which in turn enhances braking performance and safety.

[0015] Another possible embodiment of the invention is characterized in that, disc body comprises a sequential arrangement of cooling hole - formed section - cooling hole - non-formed section. Thus, this arrangement optimizes airflow and ensures that each cooling hole operates at maximum efficiency.

[0016] Another possible embodiment of the invention is characterized in that, quartercircle form of the disc body is configured to face outward on the rim in a first version. Thus, the disc body protrudes outward from the rim, optimizing airflow and directing it toward the cooling holes, thereby enabling faster cooling of the brake discs.

[0017] Another possible embodiment of the invention is characterized in that, quartercircle form of the disc body is configured to face inward on the rim in a second version. Thus, the disc body recesses inward into the rim, allowing airflow to pass closer to the disc surface, thereby increasing the amount of air passing through the cooling holes and improving braking performance.

[0018] Another possible embodiment of the invention is characterized in that, the disc body comprises at least one bolt hole for connection to the disc flat surface. Thus, the wheel is securely and firmly mounted onto the vehicle's disc flat surface, ensuring balanced wheel rotation and safe driving of the vehicle.

[0019] Another possible embodiment of the invention is characterized in that, it is compatible with both opposing wheels of the vehicle. Thus, the wheels can be used on both the left and right-side wheels. This flexibility facilitates installation and maintenance, optimizes inventory management, and allows the rims to be interchanged during use without the need for side differentiation.

[0022] Fig. 2 shows a representative first version of the rim which is the assembly of the invention.

[0023] Fig. 3 shows a representative second version of the rim that is the assembly of the invention.

[0024] DETAILED DESCRIPTION OF THE INVENTION In this detailed description, the subject of the invention is explained by way of example only for a better understanding of the subject, which shall not create any limiting effect.

[0025] The representative front view of the subject wheel (1 ) is provided in Figure 1. The subject wheel (1 ) is a metal ring onto which the vehicle’s tire is mounted. It is generally made of steel, aluminum, or alloys. The diameter and width of the wheels (1 ) directly affect tire dimensions and road grip. Larger wheels (1 ) typically allow for the use of wider tires, thereby improving road grip. The shape and design of the wheels (1) influence the overall appearance and aerodynamic properties of the vehicle. The wheels (1) are mounted onto the disc flat surface (30) using bolts or nuts, and proper installation ensures balanced rotation of the wheel and safe driving of the vehicle. The wheels (1 ) keep the tire in place when inflated, bear the vehicle’s load, and support driving dynamics such as braking, acceleration, and cornering. The subject wheel (1) is mounted onto a disc flat surface (30) on the vehicle. Essentially, the wheel (1) comprises at least one rim (10), at least one disc (20), and at least one cooling hole (24) on the said disc (20).

[0026] The rim (10) is a cylindrical structure onto which the tire is mounted. The rim (10) is formed in a cylindrical shape to ensure the safe and balanced rotation of the wheel. The edge sections of the rim (10) are configured to securely hold the tire in place and prevent it from coming off the wheel (1 ).

[0027] The disc (20) comprises at least one disc body (22) that is rounded around the inner wall of the rim (10) and a disc opening (21 ) at its center. The disc body (22) is mounted onto the disc flat surface (30). When viewed in cross-section, the disc body (22) has an approximately quarter-circle form (23). This quarter-circle form (23) ensures that the disc (20) is both aesthetically and functionally efficient. The disc body (22) is welded to the rim (10) on one side. This weld connection securely and robustly holds the disc (20) and the rim (10) together. On the other side of the disc body (22), at least one bolt hole (25) is provided to allow the wheel (1 ) to be mounted onto the vehicle. The bolt holes (25) ensure the secure attachment of the wheel (1 ) to the vehicle’s disc flat surface (30). The disc opening (21 ) forms a compatible connection point with the disc flat surface (30). Additionally, the disc body (22) includes various mounting and connection points that facilitate the integration of the wheel (1 ) with other components of the vehicle.

[0028] At least one cooling hole (24) is provided on the disc body (22) to ensure the effective cooling of the braking system. The mentioned cooling hole (24) is in the form of an opening on the disc body (22) and enables the rapid dissipation of heat generated in the brake discs during braking. The rapid dissipation of heat enhances braking performance and prevents excessive heating of brake components. The cooling hole (24) allows the brakes to function efficiently for a longer duration, thereby extending the lifespan of the braking system. The number and placement of the cooling holes (24) can be predetermined to ensure maximum cooling performance of the brake discs. These cooling holes (24) prevent excessive heating of the brake pads and discs, minimizing potential performance losses during braking.

[0029] At least one formed section (26) is provided on the disc body (22) to allow air intake into the cooling hole (24). This formed section (26) is shaped with a convex structure, protruding at least partially outward from the disc body (22). When the wheel (1) rotates, the formed section (26) facilitates air circulation, directing airflow through the cooling holes (24) toward the braking system. The formed section (26) guides airflow around the brake discs and enables faster heat dissipation. This enhances the cooling capacity of the brakes, preventing performance degradation and improving safety during braking. The number and placement of the formed sections (26) are arranged so that they are positioned between each cooling hole (24) to achieve maximum cooling performance of the brake discs. These sections help reduce excessive heating during braking, increasing the reliability and efficiency of the braking system. At least one non-formed section (27) is provided between the formed section (26) and the cooling holes (24) on the disc body (22). The mentioned non-formed section (27) maintains the continuity of the disc body's (22) rolling circle and does not have any convex structure like the formed section (26). This section allows the air turbulence created by the formed section (26) to enter the cooling hole (24). For this reason, it is positioned between the cooling holes (24). Multiple cooling holes (24) are positioned side by side on the disc body (22), with multiple formed sections (26) and non-formed sections (27) arranged between these cooling holes (24). In the preferred embodiment of the invention, a sequential arrangement of "cooling hole (24) - formed section (26) - cooling hole (24) - nonformed section (27)" is implemented in a repeated pattern. This multi-arrangement enhances the cooling efficiency of the brakes. The presence of multiple cooling holes (24) increases airflow, ensuring that heat dissipates more rapidly from the surface of the disc (20). The formed sections (26) and non-formed sections (27) between the cooling holes (24) optimize airflow and maximize the cooling efficiency of each cooling hole (24). This configuration improves braking performance and safety while also extending the lifespan of brake components. The multiple cooling holes (24) on the disc body (22) prevent excessive heating of the brake discs, thereby maintaining consistently high braking performance. These features are crucial for the overall safety and performance of the vehicle. It is specified that the quarter-circle form (23) of the disc body (22) can be designed in two different versions. These versions differ in terms of the placement of the disc (20) on the rim (10) and their ventilation characteristics.

[0030] In Figure 2, a representative view of the first version (I) of the subject wheel (1 ) is provided. In the first version (I), the quarter-circle form (23) of the disc body (22) is positioned to face outward on the rim (10). In this configuration, the disc body (22) extends outward from the rim (10). The formed sections (26) on the disc body (22) facilitate the passage of airflow over the disc (20) and direct it toward the cooling holes (24). As the wheel (1 ) rotates, the outward-facing disc body (22) optimizes airflow and ensures air circulation through the cooling holes (24) toward the braking system.

[0031] In Figure 3, a representative view of the second version (II) of the subject wheel (1 ) is provided. In the second version (II), the quarter-circle form (23) of the disc is positioned to recess inward toward the disc flat surface (30). In this configuration, the disc body (22) has an inwardly recessed structure within the rim (10). The nonformed sections (27) on the disc body (22) allow airflow to pass closer to the disc surface. During the rotation of the wheel (1 ), the inwardly recessed form directs airflow directly onto the surface of the disc (20) and toward the cooling holes (24). In both versions, the formed section (26) and the non-formed section (27) on the disc body (22) allow air to circulate during the rotation of the wheel (1) and reach the braking system through the cooling hole (24). The formed section (26) is a convex structure that either protrudes outward or recesses inward from the disc body (22). In the first version (I), this structure optimizes airflow and increases the amount of air passing through the cooling holes (24) on the disc surface. Conversely, in the second version (II), the non-formed section (27) facilitates the entry of air into the cooling holes (24). As the wheel (1 ) rotates, the formed section (26) regulates and directs airflow, ensuring effective cooling of the brake discs and pads. This cooling process enhances the performance of the braking system.

[0032] Both versions of the invention allow the wheel (1) to be used on both the left and right wheels of the vehicle. This is clearly evident from the positions of the disc body (22) and the disc flat surface (30) in Figures 2 and 3. This design flexibility facilitates the installation and maintenance of the wheels (1 ) and optimizes inventory management. It enables the interchangeability of the wheels (1 ) without requiring any distinction between sides during use. Thus, the wheels (1) provide the same performance and cooling efficiency on both sides, enhancing the reliability of the braking system and the overall driving safety of the vehicle.

[0033] As a result, the ability to design the quarter-circle form (23) of the disc (20) to either face outward or recess inward creates different airflow dynamics, optimizing brake cooling performance. In both versions, the formed section (26) and the non-formed section (27) enhance air circulation, contributing to the effective cooling of the braking system. These designs have been carefully developed to improve the overall braking performance and driving safety of the vehicle.

[0034] The scope of protection of the invention is specified in the appended claims and cannot be limited to what is described for illustrative purposes in this detailed description. It is clear that a person skilled in the art can produce similar embodiments in the light of what is explained above, without deviating from the main theme of the invention.
