Automobile frame structure

Abstract

The invention provides an automobile frame structure applied to the field of automobile chassis parts. One end of a front cross beam (3) of the automobile frame structure penetrates through a front left hole (5), and the other end of the front cross beam (3) penetrates through a front right hole (6); front left triangular blocks (7) are welded to the positions of the inner side face of a left longitudinal beam (1) and one end of the front cross beam (3), and front right triangular blocks (8) are welded to the inner side face of a right longitudinal beam (2) and the other end of the front crossbeam (3); one end of a rear cross beam (4) penetrates through a rear left hole (9), and the other end of the rear cross beam (4) penetrates through a rear right hole (10); and rear left triangular blocks (11) are welded to the positions of the inner side face of the left longitudinal beam (1) and one end of the rear cross beam (4), and rear right triangular blocks (12) are welded to the inner side face of the right longitudinal beam (2) and the other end of the rear cross beam (4). The automobile frame structure is simple in structure and cannot deform when an automobile frame bears large load or impact during travelling, the problem of cracking of welding joint parts does not occur, and bearing capability is effectively improved.

Description

Technical field [0001] The invention belongs to the field of automobile chassis parts, and more specifically, relates to an automobile frame structure. Background technique [0002] The car frame consists of longitudinal beams and cross beams. There are two main forms: side beam and middle beam. The car frame is mainly used to support the main components of the car. The structural feature of the side beam frame is that it is convenient to install the cab, carriage and some special equipment and arrange other parts. For automobile frames, it is necessary to have strong torsional rigidity and bearing capacity to facilitate the arrangement and coordination of related components. In the car frame in the prior art, the left longitudinal beam, the right longitudinal beam, the front cross beam, and the rear cross beam are simply welded. When the car frame is stressed, the deformation of the car frame itself is prone to occur, and the bearing capacity is too large or When it is not un...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a simple structure, which can stably and reliably realize the connection between the longitudinal beam and the cross beam, and effectively improve the overall rigidity of the automobile frame. When the frame is subjected to a large load or impact, the car frame will not be deformed, and there will be no cracking of the welded seam, which can effectively improve the bearing capacity and avoid the car frame structure of safety accidents.
