The middle beam (1) is a fish-bellied type structure with a variable cross section. The sleeper beam (4) and the large cross beam (3) are a double-web box-like structure with a variable cross section. The longitudinal beam (6) is an inverted U-shaped groove. The car body is a fish bone-type structure with no continuous side beam, and the bearing mode thereof is a chassis bearing, and thus the weight of the car body can be effectively reduced and the bearing capacity of the car body is improved, thereby ensuring transportation efficiency and economic benefits.
