Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy wheels, and more specifically to an aluminum alloy wheel for an off-road vehicle. Background Art

[0002] An off-road vehicle is a vehicle designed specifically for driving on rugged, roadless terrain. It usually has a high ground clearance, a powerful engine, and a four-wheel drive system to cope with adverse road conditions. Off-road vehicles are also often used for activities that require driving in wilderness or mountainous areas, such as exploration, military, and rescue missions. Due to its powerful performance and adaptability, off-road vehicles are a very practical means of transportation in many situations.

[0003] Aluminum alloy tires have the following advantages over traditional steel tires: aluminum alloy tires are relatively light, which improves fuel efficiency and driving performance; the excellent strength and rigidity of aluminum alloy materials enable the tires to perform well when subjected to loads and impacts, providing better handling and driving stability; aluminum alloys have good heat dissipation properties and can more effectively dissipate the heat generated by the braking system.

[0004] Aluminum alloy wheels are widely used in automobile manufacturing and have some significant advantages, but they also have some disadvantages: aluminum alloy wheels are relatively fragile and easily damaged by external impact and collision. Especially when off-road vehicles are driving on potholes and gravel roads, the wheel hub may be dented or scratched by the impact of stones; aluminum alloy wheels are easily affected by oxidation and corrosion, especially sewage adhering to the wheel hub for a long time, which may cause spots, rust or corrosion on the surface of the aluminum alloy wheel and the bolts.
