In groove, interconnecting piece is provided with the bolt hole of connection semi-mounted car crossbeam；Bracket, the support are connected with outer connector and interconnecting piece
Frame includes first level plate, and first level plate both ends, which are respectively perpendicular, is connected with the first vertical plate and the second vertical plate in the same direction, the
Two vertical plate upper end outside verticals are connected with the second level board；First vertical plate is connected by fastener with outer connector, the
One level board and the second level board are provided with through hole, and suspension is welded on the downside of first level plate, and the second vertical plate passes through tight
Firmware is connected with interconnecting piece.
Further, the first level plate, the second level board, the first vertical plate and the integrated knot of the second vertical plate
Structure, the height of the first vertical plate are more than the height of the second vertical plate.
Further, the first vertical plate is made up of the trapezoidal plate on top and the rectangular slab of bottom；Second level board is trapezoidal
Plate.
Further, inclined strengthening support is provided between suspension and semi-mounted car crossbeam.
Further, the outer connector, interconnecting piece, strengthening support are carbon-steel parts or Al-alloy parts, and the bracket is carbon
Steel part.
Further, the outer connector and interconnecting piece are groove profile part, and the web of outer connector and interconnecting piece is vertical
In the web of semitrailer I-shaped longeron, the web of semitrailer I-shaped longeron passes through fastener and the wing of outer connector and interconnecting piece
Face is connected.
Compared with prior art, the present invention has advantages below：
1st, the present invention solves suspension and semi-mounted turner by the mutual cooperation of outer connector, interconnecting piece and bracket
Connectivity problem between word longeron, and mitigate complete vehicle weight in the case where meeting that frame strength does not reduce.
2nd, it is big without being opened up on longeron when fixed structure provided by the invention is installed compared with existing connected mode
Through hole installation fastener is measured, a small amount of through hole is only opened up and purpose can be achieved, reduce influence of the through hole to frame strength.
3rd, on the premise of bonding strength is met, the first vertical plate top is set to trapezoidal plate, the second level board is trapezoidal
Plate, the weight of bracket can be reduced, meanwhile, manufacture outer connector and interconnecting piece using groove profile part, you can meet design requirement,
The weight of connector is reduced again, meets light-weighted requirement.
4th, the present invention is simple in construction, and easily manufactured, old cheap.
