Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a high-strength, lightweight automotive steering wheel frame. Background Technology
[0002] With the rapid development of the automotive industry, consumers' demands for vehicle performance are increasing. As a key component for drivers to control the direction of the vehicle, the performance of the steering wheel directly affects driving safety and comfort. Traditional steering wheel frames are mostly made of materials such as steel or aluminum alloys, which, while possessing a certain strength and rigidity, are insufficient in terms of lightweighting, shock absorption, noise reduction, and comfort.
[0003] Firstly, with the development of automotive lightweighting technology, reducing the overall weight of vehicles has become an important way to improve fuel efficiency and reduce emissions. Traditional steel steering wheel frames have a high density, which is not conducive to vehicle lightweighting. While materials such as aluminum alloys are lighter than steel, there is still room for improvement in areas such as shock absorption, noise reduction, and comfort.
[0004] Secondly, during driving, the steering wheel needs to withstand various forces, including the driver's grip force, the reaction force of the steering system, and vibrations from uneven road surfaces. Traditional steering wheel frame structures may experience stress concentration, deformation, or damage when dealing with these forces, affecting driving safety and comfort. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength, lightweight automotive steering wheel frame. It is integrally cast from aluminum alloy, and through a hollow structure design and the addition of reinforcing ribs, the overall rigidity and strength are improved while reducing weight. Furthermore, the detachable connection design facilitates disassembly and maintenance, enhancing ease of use.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A high-strength, lightweight automotive steering wheel frame includes a steering wheel disc for the driver to grip, a steering wheel hub connected to a steering shaft, and two steering wheel spokes connecting the steering wheel disc and the steering wheel hub. The steering wheel hub and the steering wheel spokes are fixedly connected, and the steering wheel disc and the steering wheel spokes are detachably connected via a mounting assembly. A hub cover plate is engaged with the open end of the steering wheel hub.
[0008] Preferably, the mounting assembly includes two mounting holes formed on the steering wheel spokes, and the side wall of the steering wheel has threaded holes aligned with the mounting holes, with mounting screws adapted to the threaded holes disposed in the mounting holes.
[0009] Preferably, a reinforcing rib is fixedly installed between the lower inner side of the steering wheel disc and the steering wheel hub to enhance the structural strength of the steering wheel hub.
[0010] Preferably, the reinforcing rib adopts an "arch"-shaped structure, and the contact surface with the steering wheel hub is an arc surface.
[0011] Preferably, the steering wheel disc, steering wheel spokes, and reinforcing ribs are all hollow structures and are integrally cast from aluminum alloy.
[0012] Preferably, the steering wheel, steering wheel spokes, and reinforcing ribs all have rounded corners, and the steering wheel is fitted with an anti-slip sleeve.
[0013] This utility model has the following beneficial effects:
[0014] The steering wheel rim and spokes are detachably connected via a mounting assembly, facilitating disassembly and maintenance and improving ease of use. The mounting screws feature an anti-loosening design, ensuring they will not loosen due to vibration during long-term use, thus enhancing safety.
[0015] A "bow"-shaped reinforcing rib is fixedly installed between the lower inner side of the steering wheel and the steering wheel hub, enhancing the structural strength of the steering wheel hub. The reinforcing rib has been optimized through finite element analysis to ensure it can withstand greater impact forces under extreme conditions, improving safety. The contact surface between the reinforcing rib and the steering wheel hub is an arc surface, reducing stress concentration and extending service life.
[0016] The hollow structure inside the steering wheel spokes is filled with lightweight foam material, which reduces the overall weight and effectively absorbs vibrations, improving stability during driving. The steering wheel, spokes, and reinforcing ribs all use a hollow structure and are integrally cast from aluminum alloy, improving overall rigidity and strength. Reinforcing ribs are designed inside the hollow structure, further enhancing overall rigidity while reducing weight.
[0017] The steering wheel, spokes, and reinforcing ribs all have rounded corners, reducing potential safety hazards from sharp edges. The steering wheel is fitted with a non-slip sleeve made of highly elastic silicone material with a textured surface, enhancing grip and providing a comfortable feel. Attached Figure Description

[0023] Reference Figures 1-3 A high-strength, lightweight automotive steering wheel frame includes a steering wheel 1 for the driver to grip, a steering wheel hub 3 connected to the steering shaft, and two steering wheel spokes 2 connecting the steering wheel 1 and the steering wheel hub 3. The steering wheel hub 3 and the steering wheel spokes 2 are fixedly connected, while the steering wheel 1 and the steering wheel spokes 2 are detachably connected via a mounting assembly. The mounting assembly includes two mounting holes on the steering wheel spokes 2. The side wall of the steering wheel 1 has threaded holes aligned with the mounting holes, and mounting screws 5 that are compatible with the threaded holes are provided in the mounting holes. The mounting screws 5 are designed to prevent loosening, ensuring that they will not loosen due to vibration during long-term use, thus improving safety. A hub cover 4 is snap-fitted to the open end of the steering wheel hub 3. The hub cover 4 has a snap-fit design for easy disassembly and maintenance, and its surface is matte-finished, enhancing its overall aesthetics.
[0024] A reinforcing rib 6 is fixedly installed between the lower inner side of the steering wheel rim 1 and the steering wheel hub 3 to enhance the structural strength of the steering wheel hub 3. The reinforcing rib 6 adopts an "arch"-shaped structure, and its contact surface with the steering wheel hub 3 is an arc surface. The hollow structure inside the steering wheel spokes 2 is filled with lightweight foam material, which reduces the overall weight and effectively absorbs vibration, improving stability during driving. The "arch"-shaped structure of the reinforcing rib 6 has been optimized through finite element analysis to ensure that it can withstand greater impact forces under extreme conditions. At the same time, the arc surface design reduces stress concentration and extends service life.
