Rim with an Inner Rim Flange, a Rim Base, and an Outer Rim Flange

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a wheel rim that includes an inner rim flange, a wheel center (spider), and an outer rim flange, all interconnected. The unique feature is the wheel center, which is constructed as a sandwich layer: a closed-cell metal foam core is placed between layers of thermoplastic fiber-reinforced composites, resulting in a lightweight yet robust structure.

Use CasesContent extracted from patent full text and abstract with AI.

• Automobile wheels for passenger cars and trucks
• Lightweight wheels for electric or hybrid vehicles
• Wheels for high-performance or motorsport applications
• Bicycle or motorcycle rims requiring weight reduction
• Aerospace applications where strong but lightweight wheels are necessary

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly reduced weight of the wheel rim, improving vehicle efficiency
• Enhanced structural strength and durability due to the composite sandwich structure
• Potential for better energy absorption and improved safety in crashes
• Improved vehicle handling and performance due to reduced unsprung mass
• Corrosion resistance thanks to use of thermoplastic composites

Patent Abstract

Die Erfindung betrifft Felgen mit einem inneren Felgenhorn, einem Felgenstern und einem äußeren Felgenhorn, die miteinander verbunden sind. Die Felgen zeichnen sich insbesondere durch ihre geringe Masse aus. Dazu ist der Felgenstern ein Verbund aus einem geschlossen porigen Metallschaumkörper zwischen thermoplastischen Faser-Kunststoff-Verbunden, so dass der Felgenstern einen Faserverbund/Metallschaum/Faserverbund-Sandwichaufbau aufweist.
