The invention discloses a rail transit vehicle body chassis structure, a vehicle body and a rail vehicle. The rail transit vehicle body chassis structure comprises an upper-layer structure and a lower-layer structure, and a frame beam of the upper-layer structure comprises a left middle longitudinal beam and a right middle longitudinal beam; the lower-layer structure comprises a lower-layer bottom plate, and sealing cavities are formed in the middle and the two sides of the lower-layer bottom plate; the left middle longitudinal beam and the right middle longitudinal beam are connected with the corresponding sides of the lower-layer bottom plate through the upper-layer connecting plate and the lower-layer connecting plate respectively, the lower-layer bottom plate, the left middle longitudinal beam, the right middle longitudinal beam and the upper-layer connecting plate and the lower-layer connecting plate jointly define a box-type force transmission structure, and a traction seat and a car coupler mounting seat are mounted in the box-type force transmission structure. Two sides of the upper part of the traction seat are respectively connected with the left middle longitudinal beam and the right middle longitudinal beam, and the lower part is connected with a sealing cavity in the middle of the lower-layer bottom plate; the two sides of the upper portion of the coupler mounting base are connected with the left middle longitudinal beam and the right middle longitudinal beam through upper connecting plates, and the two sides of the lower portion of the coupler mounting base are connected with the sealing cavities in the two sides of the lower-layer bottom plate through lower connecting plates. The vehicle body chassis structure has the advantages of high strength, high rigidity and light weight.
