The invention relates to the technical field of locomotive frames, in particular to a bearing frame. The bearing frame comprises end parts, a middle beam, corridor floors, an auxiliary supporting beam, cover plates and a sealing frame, the left end and the right end of the middle beam are respectively connected with one end part, the corridor floors are arranged on the front side and the rear side of the middle beam, the cover plates are arranged on the upper face and the lower face of the middle beam, the sealing frame is arranged on the cover plates, and the auxiliary supporting beam is assembled on the middle beam. On the premise that the structure of the center sill is not changed, the weight requirements of three locomotives are met by adjusting the length and the plate thickness of the center sill. The cover plate in the end assembly and the lower cover plate of the middle beam are spliced, the overall strength and rigidity of the frame are improved, and the arc-shaped design of the cover plate can reduce the stress of the cover plate. Cross beams, longitudinal beams and the like used for installing different devices on the upper portion are arranged in the middle of the middle beam. The upper cover plate, the lower cover plate and the middle air duct beam form front and rear frame air ducts to meet the ventilation requirement of the traction motor.
本发明涉及机车车架的技术领域,尤其涉及一种承载车架。这种承载车架包括端部、中梁、走廊地板、辅助支持梁、盖板和密封框,中梁的左右两端各连接一个端部,中梁的前后两侧设有走廊地板,在中梁的上、下面上设置盖板,盖板上设有密封框装,在中梁上装配有辅助支持梁。在保证中梁结构不变的前提下,通过调整中梁的长度、板厚来满足三种机车的重量要求。端部装配中的盖板与中梁的下盖板采用拼接,提高车架整体的强度和刚度,且盖板的弧形设计可以减少其应力。中梁中间布置用于上部不同设备的安装的横梁、纵梁等。采用上、下盖板和中间风道梁形成前、后架风道,来满足牵引电机的通风需求。
