Abstract
The invention discloses a supporting structure and a railway vehicle, wherein the supporting structure comprises a coupler middle front part supporting structure and a coupler tail frame middle part supporting structure; the middle-front support structure of the car coupler is fixed on a car body and used for supporting the car coupler; the coupler tail frame middle supporting structure is fixed on the coupler box fixing part and used for supporting the middle part of the coupler tail frame; and the coupler yoke pin supporting bolt mounting seat on the coupler yoke can be abutted with the middle supporting structure of the coupler yoke after the constant force connecting piece is broken, and the supporting seat of the middle supporting structure of the coupler yoke is cut off. Because the distance between the rear end of the coupler yoke pin supporting bolt mounting seat on the coupler yoke and the front end of the coupler yoke middle supporting structure is larger than the distance of the coupler moving backwards when the fixed part and the movable part constant force connecting piece of the coupler box break, the supporting seat of the coupler yoke middle supporting structure is cut off after the fixed part and the movable part constant force connecting piece of the coupler box break, and the problem that the movable part constant force connecting piece cannot be broken controllably is avoided.
