Technical Field

the invention relates to a semitrailer torsion resisting mechanism, in particular to a support reinforcing device of the semitrailer torsion resisting mechanism.

Background

the existing freight semitrailer suspension is generally divided into steel plate suspension, air suspension, hydraulic suspension and the like, wherein the steel plate suspension is simple in structure, most economical and most common. As shown in fig. 1, in the conventional steel plate suspension structure of the three-axle semitrailer, the size and height of the reinforcing box are changed according to the height change of the support 12, so as to better reinforce the support 12 and avoid the damage of the support 12. The height of a semi-trailer loading surface determines the height of a support 12, the height of the support 12 and the height of a support connecting plate 13 have a certain relation, a support reinforcing box 14 is welded in the front and rear of the connecting plate, and the support reinforcing box 14 is slightly lower than the support connecting plate 13 so as to avoid interference between the support reinforcing box 14 and a balance arm 17. The height of the support reinforcing box 14 is generally 40mm, 60mm, 95mm, 165mm and the like, and for a support 12 below 130, the support reinforcing box 14 cannot be added, if the existing support reinforcing box 14 is added, the support reinforcing box interferes with the balance arm 17, and if the existing support reinforcing box 14 is not added, the problem that the welding part of the support and the crossbeam is cracked easily occurs. The current market generally requires that the bearing surface is reduced, and the trend of supports with heights below 130 is that a new support reinforcing device needs to be developed urgently.
