Kit for a Body-Shell Structure

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

This invention relates to a modular kit for constructing the body-shell structure of rail vehicles. The kit includes specially designed upper and lower beams (chords), cross beams, vertical columns, window rails, and front/rear modules that fit together using standardized sheet-metal joints. Most components are designed with uniform profile shapes and cross-sections, allowing for easy assembly and significant flexibility in constructing rail vehicle bodies of varying sizes and configurations.

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

• Assembly of various types of rail vehicles, including passenger trains, trams, and subway cars
• Customization and rapid prototyping of new rail vehicle models for different customer requirements
• Repair and upgrade of existing rail vehicle bodies using standardized modules and joints
• Manufacture of lightweight and strong space-frame structures for transportation vehicles
• Adaptation of car body-shells to different vehicle lengths and widths with minimal redesign

BenefitsContent extracted from patent full text and abstract with AI.

• Substantially reduces development and production time thanks to modular and standardized elements
• Lowers manufacturing costs by minimizing the number of unique parts and streamlining production processes
• Improves product safety and consistency due to repeatable designs and reduced manual craftsmanship
• Allows for flexible vehicle design and easy adaptation to customer-specific requirements
• Simplifies logistics, production, and spare part management by using a limited set of profiles and joints
• Facilitates efficient repairs and upgrades, as modules and joints are easily replaceable

Patent Abstract

An embodiment of the present invention discloses a kit for a body-shell structure of a rail vehicle, including a carrier structure with at least two upper belts and a plurality of roof cross members for the roof region of the space frame, at least two lower belts and a plurality of bottom cross members for a bottom region of the body, a plurality of columns running perpendicular and a plurality of window belts for side regions of the body. An embodiment of the present invention further includes at least one head module, wherein the shell structure has a modular design. The upper belts and the lower belts are connected via knots to adjoining cross members, perpendicular columns and/or window belts, wherein the upper belts and the lower belts have a uniform profile cross-section and the knots are at least partially of uniform design.
