Beam assembly, the junction of left top cover web beam assembly and respective " several " character form structure of right top cover web beam assembly and top cover
Falling the junction of " several " character form structure corresponding on middle buttress brace assembly is buckled together and by the junction of " several " character form structure
Both ends weld to form rectangular cavities with the both ends of the junction of " several " character form structure in corresponding top cover on buttress brace assembly,
Left back roof rai assembly and right back header longeron assembly are that " several " character form structure, the left back roof rai of medial recess are total
Into with right back header longeron assembly it is respective fall " several " character form structure junction with top cover on buttress brace assembly it is corresponding
The junction stacking of " several " character form structure, which is placed and welded together, makes left back roof rai assembly and right back header longeron assembly
" several " font attachment structure is remained in that down with the junction of buttress brace assembly in top cover.
Further technical scheme includes：
Described left back roof rai assembly and right back header longeron assembly include top cover floor side member and top cover floor side member
Reinforcing plate, top cover floor side member vertically fall from top to bottom successively by horizontal on back wall upper reinforcing plate, back wall entablature buttress brace, back wall
On the body rear wall entablature assembly that beam reinforcing plate and back wall upper cross beam welding form, indulged after top cover floor side member assembly and right top cover
Beam assembly is fixed by the back wall of screw and vehicle body.
The material of back wall upper reinforcing plate uses model DP590 high-strength steel, thickness 2mm.
The beneficial effects of the utility model are compared with prior art：
A kind of high top Roof Frame girder construction of commercial car metal described in the utility model in top cover buttress brace assembly with
The connecting portion of other beam assemblies forms cavity, adds the bonding strength between each beam assembly of top cover and the company of top cover and back wall
Connect intensity.This roof rail frame structure is thick without particular/special requirement to the Metal plate and material of each beam, and girder construction is simple, for drop weight
There is preferable contribution with Sheet Metal Forming Technology.On the premise of roof rail assembly weight and technology difficulty is not increased, the high top of novel metal
Top cover girder construction has preferable structural strength, can more uniformly spread the back wall power of matching top pressure intensity, so as to what is reduced
The thickness of slab of rear grit and the quantity of buttress brace, make the back wall drop nearly 10kg of weight, while top pressure can reach 112KN.
