Description

A TUBELESS VEHICLE WHEEL WITHOUT WELDING FIELD

[0001] The embodiment herein generally relates to the field of manufacturing a tubeless vehicle wheel without welding. More specifically, the embodiment provides a single-piece tubeless vehicle wheel without welding, ensuring improved structural integrity, durability, and air retention efficiency.BACKGROUND AND PRIOR ART

[0002] In general, various methods are followed for manufacturing a wheel for a vehicle. The wheels can be made by assembling a multi piece wheel or the wheels can be manufactured using a single piece. Multi piece wheel manufacturing 15 process involves a central disc of the wheel and a wheel rim formed separately. Further, the central disc and wheel rim have to be assembled accordingly and welded together as a final wheel for a vehicle. In case of a single piece wheel manufacturing process, the whole wheel is formed using a single blank.

[0003] Generally, raw material consumption is low in a single piece wheel manufacturing process when compared to a multi piece wheel manufacturing process. Further, stress concentration due to welding is eliminated in a single piece wheel manufacturing process as welding process is not required. In addition, the production cost for manufacturing a single wheel is lower when compared to manufacturing a multi piece wheel.

[0004] The present application is a Patent of Addition to Indian Patent 482060. While the parent patent (482060) describes the process for manufacturing a single-piece tubeless vehicle wheel, existing prior art does not sufficiently address structural optimizations in the final wheel product, particularly in terms of material distribution, load-bearing capacity, and air retention efficiency.

[0005] Furthermore, the rim profile, bead seats, and well region in existing wheels often lack structural optimization for improved tire fitment, air sealing efficiency, and load distribution, making them less effective for tubeless applications.

[0006] Additionally, conventional wheel designs do not effectively integrate controlled material distribution, particularly in the disc region and rim profile, leading to unnecessary weight and compromised structural strength. The flange regions in existing wheels may also be prone to deformation under impact, affecting long-term durability and performance

[0007] Therefore, there is a need to develop a process for manufacturing tubeless vehicle wheel. Further, there is a need for a process for manufacturing tubeless vehicle wheel without welding using a single hoop. Furthermore, there is a need for a process for manufacturing tubeless vehicle wheel without subjecting the work piece to more stress and tension.

[0008] Therefore, there is a need for a single-piece tubeless vehicle wheel without welding that overcomes the structural limitations of existing wheels, ensuring enhanced durability, optimized weight distribution, improved air retention, and increased load-bearing capacity. There is also a need for a tubeless vehicle wheel design with structurally optimized bead seats, well region, and flanges to improve tire fitment, air sealing efficiency, and impact resistance. Additionally, there is a need for a wheel design with controlled material distribution, particularly in the disc region and rim profile, to achieve weight reduction while maintaining structural strength.OBJECTS

[0063] According to an embodiment, the present disclosure provides a singlepiece tubeless vehicle wheel formed from a hoop (100) without welding, ensuring seamless structural integrity, optimized weight distribution, and enhanced air retention efficiency. The hoop (100) comprises an outboard end (101), a center region (102), and an inboard end (103), maintaining uniform material properties throughout its structure. The absence of welding eliminates stress concentration points, thereby improving fatigue resistance and increasing durability under operational loads.

[0064] In an embodiment, the wheel structure comprises a disc region (401), a nave region (403), and a rim profile (402), each formed through a combination of spinning, flow forming, and press-forming processes to achieve a seamless and high-strength structure. The disc region (401) is shaped by spinning the outboard end (101) of the hoop (100) at a rotational speed ranging from about 200 RPM to 1000 RPM, followed by controlled deformation at a temperature between 200°C and 700°C to introduce vent holes (901) for airflow regulation and coolant used for reduce temperature to room temperature. The disc region (401) is further structured to balance rigidity and flexibility, ensuring efficient load transfer andresistance to impact forces during operation. The **nave region (403) is formed from the shaped disc region (401), where bolt holes (404) are introduced using a precision punching process to ensure secure attachment to a vehicle hub. The bolt holes (404) are positioned within a tolerance range of ±0.2 mm to maintain uniform stress distribution across the nave region (403), reducing the risk of localized stress failures and ensuring a robust connection between the wheel and the vehicle.

[0065] In an embodiment, the rim profde (402) includes a bead seat (701) and a well region (703), both formed through a flow-forming process applying axial forces ranging from 250 kN to 600 kN and Radial Force from 400 kN to 800 kN, to ensure airtight sealing and enhance tire fitment. The bead seat (701) is contoured with a predetermined angle to provide an improved engagement surface for the tire bead, preventing air loss and improving tubeless functionality. The optimized shape of the bead seat (701) enhances the tire's grip on the wheel, minimizing the possibility of bead unseating under high dynamic loads. The well region (703) is structured to facilitate efficient tire mounting and balanced load distribution across the wheel structure. The depth of the well region (703) ranges between 25 mm and 35 mm, accommodating different tire profiles to ensure compatibility with a range of tubeless tires.

[0066] In an embodiment, the outboard flange (502) and inboard flange (704) are formed using a press-forming process and further reinforced through a secondary forming operation to enhance impact resistance and fatigue life. The outboard flange (502) is shaped to retain the tire bead securely, ensuring stability during high-speed and high-load conditions. The flange profile is engineered to resist deformation caused by lateral forces and road impacts, contributing to the overall longevity of the wheel. The inboard flange (704) provides structuralreinforcement for load-bearing applications and enhances the durability of the wheel under dynamic stress. The reinforcement of the inboard flange (704) reduces flexing, ensuring a stable interface between the wheel and the tire under varying operating conditions.

[0067] In an embodiment, the vent holes (901) and valve hole (902) are introduced using a precision punching process at predetermined positions to regulate airflow and improve the performance of the tubeless system. The vent holes (901) have diameters ranging between 25 mm and 45 mm, facilitating uniform air circulation within the wheel cavity, preventing pressure differentials that could affect wheel balance and performance. The valve hole (902) is strategically placed within ±1 mm tolerance for efficient inflation and pressure management, allowing for quick and reliable air adjustments. The shape and positioning of the valve hole (902) ensure compatibility with standard tubeless valve stems, providing a secure seal and preventing air leakage.

[0068] In an embodiment, the rim profile (402) is formed with a concave shape (601) through spinning, ensuring improved load distribution and structural reinforcement. The curvature of the rim profile (402) is designed with a radius ranging between 0.5 mm and 200 mm, optimizing the wheel’s resistance to bending and torsional forces, enhancing its ability to withstand heavy loads and rough road conditions. The controlled material distribution strategy within the rim profile (402) and disc region (401) ensures optimized weight reduction while maintaining mechanical performance, leading to enhanced vehicle efficiency, reduced rotational inertia, and improved handling characteristics. By strategically redistributing material within the wheel structure, the overall mass is minimized without compromising strength, allowing for better fuel efficiency and improved suspension response.

[0069] In an embodiment, the wheel is manufactured using a combination of spinning, flow forming, and press-forming techniques, ensuring a single-piece structure with uniform stress distribution and improved fatigue resistance. The absence of welding eliminates weak points associated with thermal stress, providing long-lasting durability for commercial and passenger vehicle applications. The uniform material properties maintained throughout the wheel enhance its reliability, making it suitable for high-performance applications where strength, weight reduction, and air retention efficiency are critical factors.
