The invention discloses a bogie frame, a bogie and a railway vehicle. The bogie frame comprises a main frame body, an auxiliary frame body and a brake mounting seat, the main framework body comprises two side beams, a first cross beam and a second cross beam; a first mounting hole and a second mounting hole are formed in each side beam; two ends of the first cross beam respectively penetrate through the two first mounting holes and are fixedly connected with the two side beams; two ends of the second cross beam respectively penetrate through the two second mounting holes and are fixedly connected with the two side beams; the auxiliary framework body is located between the two side beams and penetrates through the first cross beam and the second cross beam. The secondary framework body comprises two longitudinal beams and two reinforcing beams; the two reinforcing beams are perpendicular to the longitudinal beams and arranged at the ends of the longitudinal beams. The brake mounting base is of a double-clamping-plate structure and is fixedly connected with the reinforcing beam. The bogie frame can meet the strength requirements for the running speed of 160 km/h and the axle load of 21 t or above, meanwhile, the installation strength of a brake and the braking effect of a vehicle are met, and safe running of the vehicle is guaranteed.
