Description

Technical Field

[0001] The utility model relates to the technical field of automobile tubeless wheels, in particular to a wheel. Background Art

[0002] Automobile wheels are components designed for movement, appearance, and safety. Traditionally, automobile wheels have mostly been formed from cast iron alloys, alloy structural steels, or other lightweight materials. Cast iron alloy or alloy structural steel wheels offer high strength and toughness, but due to their high density, they are heavy for a given thickness. Material properties also limit the design of their exterior styling. Lightweight, single-material materials, such as aluminum alloys, have a density and elastic modulus only one-third that of steel. Therefore, a larger volume of aluminum alloy is required to meet the product's rigidity and strength requirements. Furthermore, the preparation of aluminum alloys carries challenges such as high energy consumption and high carbon emissions. Therefore, while maintaining the original load-bearing capacity, the lighter steel-aluminum structured wheels are becoming increasingly popular.

[0003] Currently, due to the difficulty in welding and fixing aluminum and steel in steel-aluminum wheels, existing steel-aluminum wheels are connected and welded together using connectors at the bottom groove of the steel rim. Part of the connector is cast into the aluminum spoke, while part is bonded to the steel rim. This connection at the bottom groove of the steel rim results in increased material usage and weight in the aluminum spoke, failing to meet lightweighting requirements. Furthermore, since the connector is partially covered by aluminum, a gap exists at the joint between the aluminum and steel rim. This gap is visible from the outside, resulting in a poor overall aesthetic. Utility Model Content
