<p>FRAME LONGITUDINAL BEAM STRUCTURE FOR CHASSIS FRAMES OF UTILITY VEHICLES, IN PARTICULAR OF TRUCKS AND/OR BUSES The invention relates to a frame longitudinal beam structure for chassis frames of utility vehicles, in particular of trucks and/or buses, having at least one frame longitudinal beam (2) of modular construction which extends in the vehicle longitudinal direction when in the mounted state, wherein the frame longitudinal beam (2) has a base profile (3) which extends substantially over the entire length of the frame longitudinal beam (2) and which has a plate shaped central web (3a) which, as viewed in cross section, extends between opposite frame longitudinal beam regions, in particular between an upper flange region and a lower flange region of the frame longitudinal beam (2), which central web (3a) runs substantially rectilinearly as viewed in the direction of the longitudinal extent of the base profile, and to which central web (3a) supplemental profiles (4, 5) formed by separate components are attached in areal abutting connection. A plurality of supplemental profiles (4, 5) are attached to the central web (3a), which runs substantially rectilinearly and substantially over the entire length of the frame longitudinal beam (2), of the base profile (3) such that, in the direction of extent of the longitudinal beam, at least two frame longitudinal beam regions (6, 7, 8) of different frame longitudinal beam profile cross section are formed. Also proposed is a method for producing a frame longitudinal beam. .o</p> |
