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 consists of an inner and outer rim flange and a wheel spider (hub). The unique aspect is that the wheel spider is constructed as a sandwich structure: a closed-cell metal foam core is placed between layers of thermoplastic fiber-reinforced plastics. This layered design combines the properties of metal and advanced composites for better performance.
