Motor vehicle frame structure

Abstract

The invention provides a motor vehicle frame structure which is applied to the field of vehicle chassis parts. A front left hole (5) is formed in the front portion of a left longitudinal beam (1) of the motor vehicle frame structure, and a front right hole (6) is formed in the front portion of a right longitudinal beam (2); one end of a front cross beam (3) penetrates through the front left hole (5), and the other end of the front cross beam (3) penetrates through the front right hole (6); and a front left protruded block (31) arranged on the upper surface of the front portion of the left longitudinal beam (1) is arranged on the position, located above the front left hole (5), of the left longitudinal beam (1), and a front right protruded block (32) arranged on the upper surface of the front portion of the right longitudinal beam (2) is arranged on the position, located above the front right hole (6), of the right longitudinal beam (2). According to the motor vehicle frame structure, the structure is simple, the integral rigidity of a vehicle frame can be effectively improved, when large loads or impact are borne by the vehicle frame in the travelling process, the problems that thevehicle frame deforms, and welding joints crack can be avoided, the bearing capacity is effectively improved, and the safety accident is avoided.

Description

technical field [0001] The invention belongs to the field of automobile chassis components, and more specifically relates to a motor vehicle frame structure. Background technique [0002] The car frame is composed of longitudinal beams and beams. Its form mainly has two kinds of side beam type and middle beam type, and the car frame is mainly to support and carry the main components on the car. The structural feature of the side beam frame is that it is convenient to install the driver's cab, compartment and some special equipment and arrange other components. For the automobile frame, it needs to have strong torsional rigidity and bearing capacity, so as to facilitate the arrangement and mutual cooperation of related components. However, the automobile frame in the prior art is simply welded to the left longitudinal beam, right longitudinal beam, front beam, and rear beam. When it is uneven, cracking at the welding seam will occur, which will affect the normal use of the...

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 subjected to a large load or impact, the car frame will not deform, and there will be no cracking of the welded seam, which can improve the bearing capacity and avoid the occurrence of safety accidents.
