Description

Technical Field

[0001] The utility model relates to a frame assembly for a truck, belonging to the technical field of automobile parts. Background Art

[0002] When light trucks are used in mountainous areas with poor road conditions and heavy loads, there is a risk of insufficient load-bearing capacity and frame torsion and tearing. Traditional light trucks cannot meet the harsh working conditions in mountainous areas, which can easily cause frame tearing. The rear overhang and front crossbeam of traditional light truck frames are connected by a single crossbeam, which has poor torsion resistance; the four crossbeams of traditional light truck frames are installed in fixed holes, which is not conducive to modification. For example: Patent document CN202987274U discloses "a light truck frame with a new structure", in which the ends of the longitudinal beams adopt a dovetail structure and the crossbeams mostly adopt a tubular beam structure. The overall strength of the frame is poor and the load-bearing capacity is weak; Patent document CN213384450U discloses "a lightweight light truck frame assembly", in which the ends of the longitudinal beams adopt a dovetail structure. The longitudinal beams are only partially reinforced at the front and rear overhang beams, and the rear overhang and front crossbeam assembly is a single crossbeam structure. Under mountainous road conditions, the frame is very prone to torsional deformation and cracking. Summary of the Invention

The front cross beam, the second cross beam, the third cross beam and the fourth cross beam are arranged in sequence from front to back at the front of the left longitudinal beam and the right longitudinal beam, and the rear tail beam, the spare tire cross beam, the rear overhang rear cross beam assembly and the rear overhang front cross beam assembly are arranged in sequence from back to front at the rear of the left longitudinal beam and the right longitudinal beam; standard holes are arranged in front of the left longitudinal beam and the right longitudinal beam, and the relative installation spacing between the front cross beam, the second cross beam, the third cross beam and the fourth cross beam can be adjusted according to the chassis layout; the rear overhang front cross beam assembly is a double cross beam structure.

[0005] The through-type left reinforcing beam and the through-type right reinforcing beam are both integral structures of C-shaped cross-sections and are respectively fixed to the left longitudinal beam and the right longitudinal beam between the second cross beam and the third cross beam by bolts.

[0006] The rear-suspension front cross beam assembly includes a rear-suspension front cross beam connecting plate and two rear-suspension front cross beams. U-shaped holes are provided at both ends of the rear-suspension front cross beams to facilitate the assembly of the double cross beams and the layout of pipelines. The two ends of the two rear-suspension front cross beams are connected to the left longitudinal beam and the right longitudinal beam through the rear-suspension front cross beam connecting plate.

[0007] The length of the rear overhang front cross beam connecting plate is longer than the width of the two rear overhang front cross beams.

[0008] The left bracket and the right bracket are respectively fixed on the left longitudinal beam and the right longitudinal beam between the rear overhang front cross beam assembly and the rear overhang rear cross beam assembly.
