Detailed Description
It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1, the frame structure for the new energy commercial truck comprises two parallel frame longitudinal beams 1 and three frame cross beams 2. The frame cross member 2 penetrates the frame rail 1 and is welded and fixed thereto.
The structure of the frame longitudinal beam 1 is formed by welding two C-shaped beams, and the cross section of the longitudinal beam is shown in figure 2. The frame longitudinal beam adopts the form of two C-shaped beam buckles, and the two C-shaped beams are respectively an outer C-shaped beam 11 and an inner C-shaped beam 12. The joint adopts intermittent welding, and is supported and reinforced, the outer side C-shaped beam plays a main bearing role, the inner side C-shaped beam is an auxiliary bearing, and conditions are created for reducing the material consumption of the inner side C-shaped beam.
Compared with the existing square tube longitudinal beam structure, the structure has the advantage that the bearing capacity and the tensile strength are obviously improved. The static loading test of the quality shows that 626kg of the novel longitudinal beam structure is loaded, the deformation of the square tubular longitudinal beam is 2.1mm, the deformation of the square tubular longitudinal beam is 5.5mm, 1167kg of the novel longitudinal beam structure is loaded, the deformation of the square tubular longitudinal beam is 8.0mm, 1780kg of the novel longitudinal beam structure is loaded, the deformation of the square tubular longitudinal beam is 7.6mm, the deformation of the square tubular longitudinal beam is 16.3mm, the elastic deformation of the loading is only about 1/2 of the square tubular longitudinal beam structure, the plastic deformation of the novel longitudinal beam structure is 1.4mm, the plastic deformation of the square tubular longitudinal beam is 4.0mm, and the plastic deformation is only about 1/3 of the square tubular longitudinal beam structure.
The frame cross member 2 is constructed in the form of a frame rail 1, which is smaller in cross-sectional dimension than the frame rail 1.
As shown in fig. 3-5, the middle part of the side surface of the frame longitudinal beam 1 is hollowed out to form a hollowed-out hole, and the shape of the hollowed-out hole is matched with the shape of the cross section of the frame cross beam 2. The frame cross beam 2 penetrates through a hollowed-out hole of the frame longitudinal beam 1, and a sealing plate 3 is arranged on the outer side face of the hollowed-out hole and is fixed with the frame longitudinal beam.
After the frame cross beam 2 penetrates through the frame longitudinal beam 1, the two contact surfaces are connected in a welding mode, and as the contact surfaces are large and the two contact surfaces are in penetrating lap joint, the torsional strength is low compared with the surface welding in the traditional process, and the integral torsional strength of the frame is improved.
In the present embodiment, the cross-sectional shapes of the frame rail 1 and the frame cross member 2 are both substantially square, and are merely examples. Under the condition that the cross sections of the frame longitudinal beam 1 and the frame cross beam 2 adopt other shapes, the effect of improving the strength can be achieved as long as the two C-shaped beam buckling structural forms are adopted, and the homography should fall into the protection scope of the technical scheme.
