Disclosed is a flat car body. The chassis of the car body comprises: a middle beam (1), two ends of the middle beam (1) being provided with an end beam (2) respectively; a large cross beam (3), the large cross beam (3) being provided in a middle part of the middle beam (1); a sleeper beam (4), the sleeper beam (4) being provided between the end beam (2) and the large cross beam (3); a small cross beam (5), the small cross beam (5) being provided between the large cross beam (3) and the sleeper beam (4); a longitudinal beam (6), the longitudinal beam (6) being provided between the end beam (2) and the sleeper beam (4); and a marked beam (7), the marked beam (7) being provided between the small cross beam (5) and the large cross beam (3). 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.
