Thus, the rib plate 40 is arranged to enable the welding strength between the first side edge 44 and the upper cover plate 31 and between the web 33 and the second side edge 45 to be higher, so that the rib plate 40 and the center plate beam 30 are welded more firmly, and the overall structural strength of the bogie is further improved. Meanwhile, the structure is simple, the processing and the realization are easy, and the processing cost of the bogie is reduced.
Optionally, the length b of the third side 46 and the length a of the first side 44 satisfy:In the present embodiment, the length b of the third side 46 and the length a of the first side 44 satisfy:Thus, the rib 40 has inclined side edges, and when the vertical load acting on the upper cover plate 31 is transmitted to the rib 40, the vertical load is decomposed in two directions on the inclined side edges, so that structural damage of the rib 40 is prevented, and the service life of the rib 40 is prolonged.
It should be noted that the size relationship between the length b of the third side 46 and the length a of the first side 44 is not limited thereto, as long as the production requirement can be met.
As shown in fig. 2 and 4, each rib plate 40 further has a fourth side 47, the second side 45 is connected to the first side 44 through the fourth side 47, the fourth side 47 and the first side 44 form a first included angle, the fourth side 47 and the second side 45 form a second included angle, and an avoiding gap 471 for avoiding a weld is formed between the fourth side 47 and the upper cover plate 31 and the web 33. Thus, the arrangement makes the welding between the rib plate 40 and the central disk beam 30 more compact and firm, and improves the structural strength of the bogie.
In the present embodiment, the projection of the first side 44 on the upper deck 31 is within the upper deck 31 in the height direction of the center sill 30. Thus, the above arrangement prevents the first side edge 44 from leaking out in the height direction of the center sill 30 to prevent the first side edge 44 from structurally interfering with other structures on the truck. Meanwhile, the bogie is more attractive in appearance due to the arrangement.
Optionally, the web 33 has a preset distance a from the side edge of the upper cover plate 31, and the length a of the first side edge 44 satisfies the following distance a:In the present embodiment, the length a of the first side 44 and the preset distance a satisfy:
As shown in fig. 1, the upper cover plate 31 has a threaded hole 311, and all rib plates 40 are disposed avoiding the threaded hole 311. Thus, the arrangement prevents the rib 40 welded to the upper cover plate 31 from being structurally interfered with the fastener passing through the threaded hole 311, thereby improving the structural reliability of the bogie.
Optionally, at least some of the rib plates 40 are arranged at intervals along the length direction of the upper cover plate 31. In the present embodiment, three rib plates 40 of the six rib plates 40 are located at the front side of the upper cover plate 31 and are spaced apart in the longitudinal direction of the upper cover plate 31, and the other three rib plates 40 of the six rib plates 40 are located at the rear side of the upper cover plate 31 and are spaced apart in the longitudinal direction of the upper cover plate 31.
The present application further provides a vehicle (not shown) including a bogie. Wherein, the bogie is the bogie.
