The sleeper beam structure comprises a middle sectional material and outer side sectional materials which are arranged side by side in the length direction of a vehicle body, and the two outer side sectional materials are provided with inner cavity structures which are symmetrically arranged; the middle profile is an integral profile and comprises a middle top plate, a middle bottom plate, a left side plate, a right side plate and a first set of rib plates located in an inner cavity. The outer side profile is an integral profile and comprises an outer side top plate, an outer side bottom plate, an outer side edge plate and a second group of rib plates positioned in the inner cavity; outer side top plates of the two outer side section bars are connected with a middle top plate of the middle section bar in a welded mode through two welding seams, and outer side bottom plates of the two outer side section bars are connected with a middle bottom plate of the middle section bar in a welded mode through two welding seams. According to the sleeper beam structure, the manufacturing difficulty can be effectively reduced, the adjusting and repairing workload is greatly reduced, the longitudinal load transmission capacity and the overall structural strength are improved, and the local stress level is reduced.

    本发明公开了一种枕梁结构、底架及轨道车辆,包括沿车体长度方向并排设置的中间型材和外侧型材,两个所述外侧型材具有对称设置的内腔结构;所述中间型材为整体型材,其包括中间顶板、中间底板、左侧板、右侧板以及位于内腔中的第一组筋板;所述外侧型材为整体型材,其包括外侧顶板、外侧底板、外侧边板以及位于内腔中的第二组筋板;两个所述外侧型材的外侧顶板通过两道焊缝与所述中间型材的中间顶板焊接连接,两个所述外侧型材的外侧底板通过两道焊缝与所述中间型材的中间底板焊接连接。该枕梁结构能有效降低制造难度,大大减少调修工作量,提高纵向载荷传递能力和整体结构强度,降低局部应力水平。
