Chassis structure for e.g. rail vehicle, has lattice structure that is formed in longitudinal direction and is provided with adjacent lattice bars which are transverse to longitudinal direction

摘要

The chassis structure has a base unit that is connected with roof unit (16) through wall units (22, 24). A lattice structure (30) is formed in longitudinal direction (12) and is provided with adjacent lattice bars (34, 42, 46, 48) which are transverse to longitudinal direction. The lattice structure includes successive grid openings (74,84) formed in rows (62, 72, 82). The grip openings of adjacent rows are formed in transverse direction.
