Title:
CONNECTING STRUCTURE FOR CHASSIS SIDE BEAM OF RAIL VEHICLE HAVING DRUM-SHAPED VEHICLE BODY
Document Type and Number:
WIPO Patent Application WO/2022/062110
Kind Code:
A1
Abstract:
A connecting structure for a chassis side beam of a rail vehicle having a drum-shaped vehicle body, comprising a chassis side beam (1), a chassis cross beam (3), a side wall upright column (5) and a side wall plate (6); the chassis side beam (1) is a roll bending member, has a cross section of a groove-shaped structure, and has a side face (14), an upper wing face (10) and a lower wing face (11); the side face has an inclination angle consistent with that of the side wall plate (6), a recessed pressing platform (13) is provided at the upper end of the outer side of the side face (14), the side wall plate (6) is overlapped on the pressing platform (13) and is butt welded to the pressing platform for fixation; the inner end of the lower wing face (11) is vertically turned downwards to form a flange (12), a vertical plate (2) is welded and fixed between the upper wing face (10) and the lower wing face (11), the inner side face of the vertical plate (2) is coplanar with the inner side face of the vertical flange (12), and serves as a mounting surface for an under-vehicle device hanger (7); and the upper plane of the chassis cross beam (3) is flush with the upper wing face (10) of the chassis side beam, and the two ends of the chassis cross beam (3) are welded and fixed to the inner surface on the side face (14) of the chassis side beam. Said structure makes under-vehicle devices be hung on a side beam, solves the problem of relatively large fatigue stress at the junction of a side wall upright column and a floor, reduces the machining difficulty and assembly difficulty of a cross beam, and reduces the weight of a vehicle body.
