Abstract
The invention relates to the field of automobile manufacturing, and discloses an integrated automobile frame and a manufacturing method thereof. The integrated automobile frame includes a frame main body, and the frame main body includes a first longitudinal beam and parallel and side-by-side beams arranged side by side with the first longitudinal beam. The second longitudinal beam, the cross beam component is arranged between the first longitudinal beam and the second longitudinal beam, and the first longitudinal beam, the second longitudinal beam and the cross beam component are metal extruded integrally formed structures. Compared with the existing automobile frame, the first longitudinal beam, the second longitudinal beam and the cross member of the integrated automobile frame of the present invention are integrally formed by metal extrusion, no need for separate production, processing and assembly molding, and its structure is simple The method solves the problems in the prior art that the separate production and processing of the beam and the longitudinal beam is complicated and the accuracy of the assembly and connection of the beam and the longitudinal beam is difficult to guarantee.
Description
technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an integrated automobile frame and a manufacturing method thereof. Background technique [0002] At present, the frame of lightweight tractors generally adopts the side beam structure, which has the advantages of simple structure, which is conducive to expanding the serialization of different wheelbases, the needs of multi-variety models and modified vehicles, and has good versatility. [0003] In the prior art, the manufacturing process of the longitudinal beam and the cross beam is simple and mature, which facilitates the fixed installation of other assemblies and components, and the installation position is easy to adjust. Among them, the side beam frame is composed of longitudinal beams and cross beams, and the longitudinal beams and cross beams are mostly stamped or rolled by steel plates. In actual production, longitudinal beams and beams are usually processed and f...
