Aluminum honeycombfloor structure is directly laid in this floor.
This buffer beam is connected by buffer beam backing plate with floor.
The both sides attachment weld that this buffer beam backing plate is connected with floor is arranged on the first floor reinforcement plate node place that floor profile local thickeies, and arranges two row's plug welding holes in the centre of buffer beam backing plate.
This sleeper beam is connected with floor by sleeper beam backing plate.
This sleeper beam is provided with the kingpin hole for being connected and fixed with bogie truck, arranges sleeper beam rebound in kingpin hole side.
This sleeper beam rebound is arranged on the second floor reinforcement plate node on floor.
Compared with prior art, the beneficial effect that the utility model has is:
1, the utility model is by adopting elongated floor, floor is extended to draw beam place, is connected by H type tie-beam, cancel original short floor panel structure, and floor Undercarriage structure is simplified, and reduces section bar die sinking kind, reduces productive costs;
2, upper and lower surface, the utility model floor overlaps respectively and is fixed on the tie-beam of falling H type, and floor forms closed cavity structure with the junction of the tie-beam of falling H type, regulates surplus for bottom frame floor assembly welding provides larger welding;
3, the utility model arranges sleeper beam backing plate, buffer beam backing plate respectively in the junction of floor and sleeper beam, buffer beam, is used for regulating bottom frame floor deformation of assembly welding excessive and occurring the untight phenomenon of overlap joint, has good manufacturability;
4, the floor profile local of the utility model buffer beam backing plate commissure thickeies, and ensures that floor profile is not by burn-through;
5, between the utility model floor and sleeper beam, sleeper beam backing plate is set, floor and sleeper beam junction arrange sleeper beam rebound, and corresponding with the floor reinforcement plate node of floor profile, significantly reduce the stress concentration degree of sleeper beam and junction, long floor, ensure enough Joint strenghts;
6, aluminium honeycomb Double floor structure is directly laid on the utility model floor, can significantly reduce car body noise, improve ride quality.
Generally speaking, the utility model Undercarriage structure is simple, decreases weld seam quantity, easy modularized production, lighter in weight, and between parts, connection mode is reasonable, and intensity is good, meets the requirement of car body high-intensity performance.

Detailed description of the invention
As shown in Figure 1, the utility model Undercarriage structure mainly comprise be located at two ends draw beam 1, buffer beam 2, sleeper beam 3, floor 5 and edge beam of underframe 6.Floor 5 is between two edge beam of underframes 6, and two ends extend to draw beam 1 place, are connected with draw beam 1 by the tie-beam of falling H type 4.This buffer beam 2 is located between draw beam 1 and sleeper beam 3, and buffer beam 2 and sleeper beam 3 overlap with floor 5 and be connected.
As shown in the floor of Fig. 2 and draw beam connection diagram, one end of upper and lower two gussets of the tie-beam of falling H type 4 is welded with draw beam 1, upper and lower surface, floor 5 overlaps respectively and is fixed on the tie-beam of falling H type 4, floor 5 forms closed cavity structure 13 with the junction of the tie-beam of falling H type 4, not only Joint strenght is high, adopt overlap joint connection mode to allow elongated floor 5 have enough welding to regulate surplus simultaneously, ensure the precision in length over ends of body direction, good manufacturability.Aluminum honeycombfloor structure 10 is directly laid in floor 5, is conducive to reducing car body noise, improves ride quality.
As shown in the floor of Fig. 3 and buffer beam connection diagram, buffer beam backing plate 7 is first connected with floor 5, both sides attachment weld is arranged on the first floor reinforcement plate node 5a place that section bar local, floor 5 thickeies, ensure that floor 5 section bar is not by burn-through, arranges two row's plug welding holes 12 and strengthens the Joint strenght with floor 5 in the centre of buffer beam backing plate 7.Buffer beam 2 is connected by setting up buffer beam backing plate 7 with floor 5, avoid floor 5 linear deformation in bottom frame floor assembly welding excessive and occur with buffer beam 2 overlap untight phenomenon, there is good manufacturability.
