The invention discloses a rail train, a bogie and a framework. The framework comprises side beams, cross beams, brake beams, longitudinal beams, transverse shock absorber seats, tread shaping seats, anti-side-rolling torsion bar seats and anti-snaking shock absorber seats. Wherein the side beams, the cross beams, the brake beams, the longitudinal beams, the transverse shock absorber seats, the tread shaping seats, the side-rolling-resistant torsion bar seats and the snaking-resistant shock absorber seats are all structural parts integrally forged by titanium alloy, and the side beams and the cross beams are of I-shaped beam structures and are integrally forged by die forging. Due to the fact that titanium alloy has the performance characteristics of being low in density, high in specific strength, excellent in corrosion resistance, good in high-temperature strength and the like, the weight of each structural part can be reduced by designing the side beams, the cross beams, the brake beams, the longitudinal beams, the transverse shock absorber seats, the tread shaping seats, the side-rolling-resistant torsion bar seats and the snaking-resistant shock absorber seats into the structural parts formed by integrally forging the titanium alloy.
本发明公开了一种轨道列车、转向架和构架,构架包括:侧梁、横梁、制动梁、纵梁、横向减振器座、踏面修形座、抗侧滚扭杆座和抗蛇行减振器座;其中,所述侧梁、所述横梁、所述制动梁、所述纵梁、所述横向减振器座、所述踏面修形座、所述抗侧滚扭杆座和所述抗蛇行减振器座均为钛合金整体锻造的结构件,且侧梁、横梁为工字梁结构并由整体模锻锻造。由于钛合金具有密度低、比强度高、抗腐蚀性能优异、高温强度良好等性能特点,通过将侧梁、横梁、制动梁、纵梁、横向减振器座、踏面修形座、抗侧滚扭杆座和抗蛇行减振器座均设计为钛合金整体锻造的结构件,可降低各结构件的重量。
