Wherein, the transition connection bracket includes a bent bracket mounting plate, the outer side of the bent upper part of the bracket mounting plate is connected with the inner side of the belly of the frame longitudinal beam by bolts, and the inner side of the bent upper part of the bracket mounting plate is connected to the The beam is welded; the outer side of the bent lower part of the bracket mounting plate is bolted to the inner side of the lower wing surface of the frame longitudinal beam, and the lower edge of the bent lower part of the bracket mounting frame is provided with a wing plate, and the wing plate is connected to the lower wing of the frame Bolted connection to the base of the leaf spring bracket described above.

Wherein, at least one stiffener plate is welded at the bend of the bracket mounting plate, groove-shaped through ribs are welded between adjacent stiffener plates, and groove-shaped cross-sectional ribs are welded between the stiffener plate and the beam. Ribs.

Wherein, the crossbeam, the bracket mounting plate, the wing plate, the stiffener plate, the groove-shaped through rib, and the groove-shaped variable cross-section stiffener are welded as one.

The utility model adopts a beam front scheme, the front beam and the leaf spring bracket are connected and strengthened by the transition connection bracket welded together with the beam, the front beam effectively avoids the space occupied by the engine, and the transition connection bracket and the leaf spring bracket adopt Bolted. For the transitional connection bracket, the bracket mounting plate is welded together with the beam, and is integrally strengthened by welding the stiffener plate, the groove-shaped cross-section stiffener and the groove-shaped through-beam. The bracket mounting plate covers most of the front part of the frame longitudinal beam and uses bolts The connection makes the leaf spring bracket and the front part of the frame have higher strength and torsional rigidity, realizes the function of installing the beam at the front leaf spring bracket of the front suspension, and effectively enhances the strength of the front leaf spring bracket and the torsion resistance of the frame stiffness.

When installing, first connect the leaf spring bracket to the longitudinal beam of the frame, and then install the cross beam and the transition connection bracket, which are connected by bolts. The structure is simple, the manufacturability is good, and it is easy to assemble. The leaf spring bracket is strengthened by a transition connection bracket inside the frame longitudinal beam, and the bracket mounting plate shares the bolt holes with the leaf spring bracket and the frame longitudinal beam, so the structure is compact and reliable.

The beneficial effects of the utility model are: the utility model effectively avoids the space occupied by the engine through the front beam, so that the leaf spring bracket and the front part of the frame have higher strength and torsional rigidity, and realizes the installation of the beam at the leaf spring bracket. The function can effectively enhance the strength of the leaf spring bracket and the torsional rigidity of the frame.
