EXTERIOR LONGITUDINAL BEAM FOR TWIN-AXLE RAILWAY GOODS WAGGON

The invention relates to exterior longitudinal beams for twin-axle railway goods waggon, which are designed to transmit the horizontal buffer forces and to receive the vertical load of the freight and devices bearing the axles According to the invention, the exterior longitudinal beam for twin-axle railway goods waggons is built in three levels in the upper side along its length, such that it has an uppermost level (6) corresponding to the loading level, a mid level (7) as a support surface for the lower side (8) of the waggon and a lower level (9) forming the support surface for the crossbeams (10) of the railway goods waggon The exterior longitudinal beam (1) is entirely built at the same construction height, over the axles (3) to the frontal crossbeams (2) of the waggon Thus in the axle (3) area, the lower side of the exterior longitudinal beams (1) has two openings (13) for taking over the bearing housings (14) of the axles (3), said openings(13) being lockable in known manner, by means of axle (3) box guide keys(15), and the vertical sides of the openings (13) are provided with some slides (16) for restraint of the displacement of the bearing housing (14) of the axles (3) The exterior longitudinal beam has on the inner sides of the opening (13), some vertical spring leaves (18) tightly secured to the upper side of the exterior longitudinal beam (1) while in the area of the housings (14) of the axles (3) they are located at an adequate distance between the axle (3) and the exterior longitudinal beam (1) on its outer side towards the exterior of the waggon
