COMBINATION STRUCTURE OF STRUCTURE FOR RAILROAD CARS AND RAILROAD CARS USING THE SAME

摘要

PURPOSE: A composite material-formed slot coupling structure for a railway vehicle and the railway vehicle applied with the same are provided to easily coupling the structures with a strong coupling force and to easily remodel and maintain the vehicle. CONSTITUTION: A composite material-formed slot coupling structure for a railway vehicle includes a first structure (10) for the vehicle and a second structure (20) for the vehicle. A coupling protrusion (21) at the second structure is inserted into a coupling groove (11) at the first structure, and then the structures are mutually coupled. The coupling groove is formed into a shape of which three sides are closed, and is extended in the longitudinal extruding direction of the first structure. The coupling protrusion is extended in the longitudinal extruding direction of the second structure. When moving in an inserting direction into the coupling groove or in a direction opposite to the inserting direction, the coupling protrusion is separated from the coupling groove. One of the structures is formed with a composite material.
