Beschreibung
Zusammenfassung:	The utility model discloses an automobile frame cross beam which comprises an upper piece, a lower piece is fixedly welded to the bottom of the upper piece, outer connecting cambered surfaces are symmetrically arranged at the positions, close to the side wall, of the top of the upper piece, and inner connecting cambered surfaces are symmetrically arranged at the positions, close to the side wall, of the bottom of the upper piece. Positioning plates are symmetrically and fixedly connected to the corners of the bottom of the upper piece, positioning holes are formed in the middle positions of the two positioning plates and used for accurately positioning the upper piece during welding machining, and mounting holes are symmetrically formed in the positions, close to the corners of the top, of the front wall of the upper piece and used for mounting and fixing the frame cross member assembly and a frame. And reference holes are symmetrically formed in the front wall of the upper piece close to the bottoms of the t
