The cross beam 5 is structurally decoupled from the side beam body 4, and the cross beam 5 is cooperated with the side beam body 4 through the cross beam mounting hole on the side beam body 4 and is welded as a whole.

[0034] As shown in Figure 3 The side beam body 4 is divided into a main structure 6, a secondary spring mounting block 9, a current collector mounting block 7, an auxiliary device mounting block 8 and the like.

[0035] The side beam body 4 adopts a general frame structure, and the middle upper cover plate and the secondary mounting seat thereof of the general frame structure are extracted as the optional secondary spring mounting block 9. The secondary spring mounting block 9 can be configured with multiple blocks according to different projects in the platform, such as the secondary spring mounting blocks 9, 10 in the embodiment, to adapt to the rubber stack, steel spring group or hourglass spring used on bogies of different speed levels.
