[0025] like Figures 1 to 4 As shown, an embodiment of the utility model provides a bogie frame, which includes a crossbeam 10 and two side beams 20. The crossbeam 10 extends in the transverse direction; the two side beams 20 are respectively arranged at both ends of the crossbeam 10 and extend in the longitudinal direction, the side beam 20 includes an upper cover plate 21, a lower cover plate 22 and a side plate 23, the upper cover plate 21 and the lower cover plate 22 are arranged in a vertical interval, the side plate 23 extends in the vertical direction, the upper surface of the side plate 23 is connected to the middle part of the upper cover plate 21, and the lower surface of the side plate 23 is connected to the middle part of the lower cover plate 22, and the two ends of the crossbeam 10 are riveted to the side plates 23 of the two side beams 20 respectively.

[0026] By applying the technical solution of the utility model, the bogie frame includes a cross beam 10 and two side beams 20. Since the side beam 20 includes an upper cover plate 21, a lower cover plate 22 and a side plate 23, the upper surface of the side beam 20 is connected to the upper cover plate 21, and the lower surface of the side plate 23 is connected to the lower cover plate 22. The structure of the single side plate 23 can reduce the weight of the side beam 20. The two ends of the cross beam 10 are riveted to the side plates 23 of the two side beams 20 respectively. The riveted structure is used instead of the welding structure to reduce the deformation of the connection part of the cross beam 10 and the side beam 20. After the cross beam 10 or the side beam 20 fails, it can be directly disassembled to facilitate the replacement of the damaged cross beam 10 or the side beam 20. At the same time, since there is no need for welding, the flaw detection process of the weld is omitted, and there is no problem of cracks in the weld, which improves the assembly efficiency.

[0027] The upper cover plate 21 and the lower cover plate 22 are both concave structures, and the middle parts of the upper cover plate 21 and the middle parts of the lower cover plate 22 are both concave downwards.

[0028] like Figure 2 As shown, the side beam 20 further includes a connecting rib 24, and the connecting rib 24 is connected between the upper cover plate 21 and the lower cover plate 22.

The vertical rib 241 can form a connection structure for the upper cover plate 21, the lower cover plate 22 and the side plate 23, thereby strengthening the structural strength of the side beam 20.

[0030] The vertical ribs 241 are located in the middle of the upper cover plate 21 and at the concave transition, and there are multiple vertical ribs 241, which are arranged at intervals in the longitudinal direction. The cross-sectional areas of both ends of the vertical ribs 241 are increased to increase the contact area with the upper cover plate 21 and the lower cover plate 22.

[0032] In this embodiment, transverse ribs 242 are disposed on both sides of the plurality of vertical ribs 241. The width of the transverse ribs 242 is greater than the width of the vertical ribs 241, which means that the transverse ribs 242 are greater than the vertical ribs 241 in the longitudinal direction.

The brake hanger 16 can be used to connect the brake beam to the cross beam 10, thereby reducing the transverse dimension of the brake beam and simplifying the structure of the brake beam.

[0042] The upper enclosure plate 11 has a crossbeam mounting hole 111 which is vertically penetrated. The crossbeam mounting hole 111 can facilitate the assembly of the crossbeam 10 and the side beam 20 and reduce the weight of the crossbeam 10 .

[0043] In this embodiment, both the front web 12 and the rear web 14 have weight-reducing holes 17 that penetrate in the longitudinal direction. The weight-reducing holes 17 can facilitate the assembly of the cross beam 10 and the side beam 20 and reduce the weight of the cross beam 10.

[0044] Another embodiment of the present application provides a bogie, which includes the bogie frame provided above. Since the side beam 20 includes an upper cover plate 21, a lower cover plate 22 and a side plate 23, the upper surface of the side beam 20 is connected to the upper cover plate 21, and the lower surface of the side plate 23 is connected to the lower cover plate 22, the weight of the side beam 20 can be reduced by using a single side plate 23 structure. The two ends of the cross beam 10 are riveted to the side plates 23 of the two side beams 20 respectively, and the riveted structure is used instead of the welding structure, which can reduce the deformation of the connection part of the cross beam 10 and the side beam 20, and after the cross beam 10 or the side beam 20 fails, it can be directly disassembled to facilitate the replacement of the damaged cross beam 10 or the side beam 20. At the same time, since there is no need for welding, the flaw detection process of the weld is omitted, and there is no problem of cracks in the weld, which improves the assembly efficiency.
