Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] The invention relates to a heavy-duty vehicle rear balance suspension system, which comprises a cast beam assembly and a balance shaft assembly.

[0028] combine figure 2 and image 3 , The cast beam assembly includes: an integral cast beam 4 , an upper connecting plate 5 , and a lower connecting plate 6 . like figure 2 As shown, the integral cast beam adopts an integral cast structure, including a top plate 44, a bottom plate 45, a side plate 46 connecting the ends of the top plate and the bottom plate and perpendicular to it, and a vertical plate connecting the top plate, the bottom plate and the middle of the two side plates 47. The above arrangement makes the crossbeam form an "I"-shaped section in both the vertical section and the horizontal section perpendicular to the vertical plate 47. Both ends of the top plate 44 are respectively provided with tw...

Abstract

The invention relates to a rear balanced suspension system of a heavy-duty car, and provides the rear balanced suspension system of the heavy-duty car, which has the advantages that the carrying capacity is improved remarkably, the structures of all parts are more reasonable; and the connection is more stable, so that all the parts are not easily fatigued and broken. The rear balanced suspension system comprises a cast cross beam assembly and a balancing shaft assembly, wherein the cast cross beam assembly comprises an integral cast cross beam, upper connecting plates and lower connection plates; the integral cast cross beam comprises a top plate, a baseplate, side plates connected with the end parts of the top plate and the baseplate and perpendicular to the top plate and the baseplate, and a vertical plate connected with the middles of the top plate, the baseplate and the two side plates to cause the longitudinal section and the horizontal section of the cross beam to be I-shaped; and two X-shaped strengthening ribs are arranged among the front surface and the rear surface of the vertical plate, and the top plate and the baseplate. Connecting flange faces of balancing shaft brackets are connected with a connecting flange face of an auxiliary balancing shaft; and the bottoms of the two balancing shaft brackets are connected together through the auxiliary balancing shaft.

Description

technical field [0001] The invention relates to a vehicle suspension system, in particular to a rear balance suspension system on a heavy-duty vehicle. Background technique [0002] In the prior art, the rear balance suspension system of a heavy-duty vehicle using an integral balance shaft has the characteristics of high rigidity and strong load-carrying capacity, and is widely used in engineering dump vehicles and other vehicles that need to carry relatively large loads and complex road conditions. like figure 1 As shown, the rear balance suspension system includes an integral balance shaft 2 and two balance shaft brackets 1' fixed thereon. The rotation of the balance shaft relative to the balance shaft bracket is restricted, thereby constituting the balance shaft assembly. The main body of the frame beam used in the suspension system is two grooved beams 6' installed on the backrest, and two thrust rod supports 5' for fixing the upper thrust rod are riveted in each of th...
