Car Body of a Rail Vehicle

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

This invention relates to a rail vehicle car body (wagenkasten) constructed from multiple parts, where a primary flat component (the base plate or form sheet) serves as a structural foundation, onto which specifically shaped open profile sections are mounted. These open profiles, unlike conventional closed-profile supports, use less material while maintaining structural strength, and can be further reinforced and connected using specially designed node (knot) parts. The system allows for fewer welds, easier assembly, and materials savings without compromising mechanical stability.

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

• Construction of passenger train car bodies
• Manufacturing of freight railcar structures
• Design of lightweight and cost-effective tram or metro vehicle bodies
• Production of modular rail vehicle body kits
• Upgrade or retrofitting of older railcar bodies with modern, efficient structural elements

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces overall weight of the rail vehicle due to less material use
• Lowers manufacturing cost through simplified components and assembly processes
• Retains or improves the structural integrity and stability of the car body
• Minimizes the number of welds required, improving reliability and reducing labor
• Provides flexibility in design for both flat and curved wall surfaces
• Allows for easier, modular assembly and potential standardization of parts across vehicle models
• Improved manufacturing speed and quality through use of deep-drawn node components
