Above-mentioned cartridge structure comprises that also the center filler between the draw beam supports, and said center filler supports and is arranged on the center filler base plate, and is vertical with the center filler base plate.
Above-mentioned center filler base plate is the rectangular base plate that has the U-shaped breach, and the width of said U-shaped breach is equal to or less than the width of two draw beam webs.
The width of above-mentioned center filler base plate is greater than the width of draw beam lower aerofoil, and the thickness of said center filler base plate is greater than the thickness of draw beam lower aerofoil.
Above-mentioned center filler base plate is the individual layer steel plate.
Above-mentioned T type attaching parts is captiveed joint with the center filler base plate.
The utility model has the advantages that:
1, to be installed in a monoblock individual layer steel plate be on the center filler base plate to body center plate; Putting on the center filler base plate does not have the draw beam lower aerofoil, directly supports with draw beam web, body bolster diaphragm and center filler to link to each other, not cover plate under the pillow; Avoided in the existing multiple-structure; Pillow down can't be closely connected fully between cover plate and attachment face, has the gap, makes pillow cover plate and the problem that the body center plate stressing conditions is bad even ftracture down.
