Embodiment Construction

[0036] The technical solutions in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings in this embodiment. However, this should not be construed as limiting the present invention to specific embodiments, but only for explanation and understanding:

[0037] Such as Figure 1 to Figure 5 As shown, this embodiment provides a beam structure, including a beam assembly 1 , a longitudinal beam 2 and a bracket assembly 3 .

[0038] A longitudinal beam 2, a crossbeam assembly 1 is arranged between the two longitudinal beams 2, and a bracket assembly 3 is provided on the side of the longitudinal beam 2 away from the crossbeam assembly 1; the longitudinal beam 2, the The beam assembly 1 is detachably connected to the bracket assembly 3 .

[0039] The existing beam adopts a welded structure, and the thickness of the longitudinal beam 2 is relatively thin. When the jack directly acts on the longitudinal beam 2 or the beam, the longit...

Abstract

The invention discloses a cross beam structure, relates to the technical field of vehicle cross beam structures, and solves the problems that an existing cross beam structure is huge and insufficientin resistance. The cross beam structure is connected with two longitudinal beams on a frame and comprises a cross beam assembly and a support assembly, and the cross beam assembly is located between the two longitudinal beams; the support assembly is arranged on the side, away from the cross beam assembly, of each longitudinal beam and used for connecting a jack; and the longitudinal beams, the cross beam assembly and the support assembly are detachably connected. The longitudinal beams have better strength, torsion resistance and bending resistance, and the structural resistance of the wholecross beam is enhanced; and all parts more match vehicle types, and the size of the cross beam structure is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle beam structures, in particular to a beam structure. Background technique [0002] In an off-road vehicle, generally the jack and the crossbeam assembly are two independent structures. The crossbeam assembly is used to connect the left and right longitudinal beams of the chassis frame, and the jack is connected to the side of the longitudinal beam. At present, the crossbeam assembly for installing the jack generally adopts a The structure of the larger overall tailor-welded beam assembly, the inner part of the longitudinal beam is a larger box-shaped tailor-welded beam assembly, which is welded on the inner side of the longitudinal beam to connect the left and right longitudinal beams, and the outer side of the longitudinal beam is also box-shaped The tailor-welded beam assembly is welded on the outer sides of the left and right longitudinal beams and connected to the middle beam assembly. This for...
