The invention relates to the technical field of railway vehicles, and provides a bogie frame, a bogie and a railway vehicle, and the bogie frame comprises a box beam, a bearing beam, an inner vertical plate, an outer vertical plate, a bearing bottom plate, a bearing top plate and a plate spring. The box beams are hollow and respectively form mounting channels. The bearing beams are arranged on the box beams respectively. The inner vertical plates are arranged in a bent mode and connected with the bearing beams in a welded mode to define a center pin channel. And the outer vertical plate is welded with the box beam. The bearing bottom plate is connected with the box beam, the inner vertical plate and the outer vertical plate in a welded mode. The bearing top plate is located above the bearing top plate, the top of the box beam is open, the bearing top plate extends to the position above the box beam and is connected with the box beam in a welded mode to seal the top opening, and the bearing top plate is further connected with the bearing beam, the inner vertical plate and the outer vertical plate in a welded mode. The plate spring is installed in the installation channel and extends in the longitudinal direction of the box beam, and the two ends of the plate spring are each provided with a cushion block used for being connected with a wheel set shaft sleeve. The structure is simple, the strength is high, and the forming is convenient.
