The air reservoir 20 is arranged between the two suspension plates. Suspension frames of the air reservoir are respectively hung on the C-shaped hanging plates, thus, after a mounting hole in each of the suspension frame is correspondingly aligned with the mounting hole in the bottom portion of the hanging plate, the suspension frames and the hanging plate may be fixed by a bolt assembly and thus the air reservoir is mounted to the air reservoir suspension seat. Since the bottom portion of the C-shaped hanging plate can hold up the air reservoir suspension frames, the air reservoir won't fall off even if the bolt assembly becomes loose. Compared with the conventional technology, such structure has anti-fall function, greatly improves the safety and reliability of the air reservoir suspension seat, improves the safety of the operation of the wagon, optimizes the connection of the air reservoir and the wagon body, improves the force condition of the air reservoir seat, increases the strength and rigidity of the air reservoir suspension seat, and prolongs the service life of the air reservoir suspension seat and the air reservoir. [0034] As a further improvement to the above embodiment, as shown in Figures 7 to 16, for saving the installation space of the air reservoir and allowing the structure between the entire air reservoir suspension seat and the air reservoir to be more compact, both of the two hanging plates 6 are respectively located on outer sides of the two suspension plates 1, and an accommodating space 30 for accommodating the air reservoir 20 is formed between the connecting plate 5, the two suspension plates 1 and the two hanging plates 6. In this embodiment, the suspension plate located at a left side is a first suspension plate la, and the suspension plate located at a right side is a second suspension plate lb. The hanging plate fixedly connected with the first suspension plate 1 a is a first hanging plate 6a, and the hanging plate fixedly connected with the second suspension plate lb is a second hanging plate 6b. The first hanging plate 6a is located at an outer side of the first suspension plate la, and the second hanging plate 6b is located at an outer side of the second suspension plate lb. [0035] As a preferred embodiment of the above embodiment, for further enhancing the anti-fall performance of the air reservoir suspension seat, an opening end at a bottom portion of each of the hanging plates 6inclines towards an inner side of the opening of the hanging 5 7053162_1 (GHMatters) P100097.AU DENISET plate 6, and the inclined portion forms an anti-fall portion 62. In a case that the bolt assembly for connecting the air reservoir and the air reservoir suspension seat becomes loose, the air reservoir will move on the hanging plate under the operation and vibration of the wagon body. When the air reservoir suspension frame moves to an end portion of the hanging plate, the air reservoir suspension frame can be blocked by the anti-fall portion 62, avoiding the air reservoir falling from the hanging plate. [0036] In the above embodiments, the connecting plate 5 and the two hanging plates 6 are integrally formed. An accommodating space 30 for accommodating the air reservoir is provided between the two hanging plates, and the suspension seat can be easily made and installed. [0037] A railway freight train is further provided, as shown in Figures 3 to 6. The railway freight train includes a freight train body and at least one air reservoir 20 secured to the wagon body. The air reservoir 20 is securely connected to the freight train body via one air reservoir suspension seat, and the air reservoir suspension seat is the anti-fall air reservoir suspension seat for a railway freight train according to any of the above embodiments. The freight train body is provided with a bathtub-shaped plate 3 and a middle beam 2 located in a recess of the bathtub-shaped plate 3, the connecting plate 5 of the air reservoir suspension seat is welded to a bottom portion of the middle beam 2, and both of the air reservoir 20 and the air reservoir suspension seat are located in the recess of the bathtub-shaped plate 3 after being assembled. [0038] In the railway freight train, since the anti-fall air reservoir suspension seat of the railway freight train described above is employed, the air reservoir 20 is disposed between the two suspension plates land the suspension frames of the air reservoir 20 are respectively hung on the C-shaped hanging plates. After a mounting hole in the suspension frame is aligned with the mounting hole in the bottom portion of the hanging plate, the suspension frame and the hanging plate may be fixed by a bolt assembly and thus the air reservoir is mounted to the air reservoir suspension seat. Since the bottom portion of the C-shaped hanging plate can hold up the air reservoir suspension frames, the air reservoir won't fall off even if the bolt assembly becomes loose. Compared with the conventional technology, such structure has anti-fall function, greatly improves the safety and reliability of the air reservoir suspension seat. The 6 7053162_1 (GHMatters) P100097.AU DENISET present solution allows the air reservoir to be connected to the hanging plates of the air reservoir suspension seat, which adds an anti-fall structure, thus, improves the safety of the operation of the wagon, optimizes the connection of the air reservoir and the wagon body, improves the force condition of the air reservoir seat, increases the strength and rigidity of the air reservoir suspension seat, and prolongs the service life of the air reservoir suspension seat and the air reservoir.
