This structure includes the crossbeam body, connects linking bridge, wheel casing assembly, extension plate at crossbeam body both ends, and linking bridge, wheel casing assembly, the equal bilateral symmetry of extension plate set up at the both ends of crossbeam body, linking bridge have one with the first connecting portion of this body coupling of crossbeam, first connecting portion are relative the opposite side of crossbeam body is equipped with the second connecting portion of echelonment, the second connecting portion with the wheel casing assembly is connected, and the side of second connecting portion is equipped with the third connecting portion of being connected with the extension plate, and the extension plate is connected with the wheel casing assembly.
Description
Technical field
The utility model relates to automotive body structure technical field, is specifically related to a kind of machinery space front cross beam structure.
Background technology
Current motorcar body great majority adopt full-bearing type structure, and self-supporting body almost carries all load in car use procedure, and mainly comprise torsions, the load such as bending, under the effect of these load, the stiffness characteristics of motorcar body then shows important especially.Body stiffness is unreasonable, will directly affect the reliability, safety, NVH performance etc. of car.
For improving body stiffness, devise machinery space front cross beam structure in some vehicle machinery spaces and connect left and right wheel cover shock absorber bearing assembly, itself and left-right longeron wheel cover is made always to be shaped as closed circular structure, improve vehicle body front structure rigidity and left and right wheel cover shock absorber bearing assembly Y-direction dynamic stiffness, thus improve body structure stability and NVH performance.But, the left and right wheel cover shock absorber bearing assembly of this structure, owing to having larger dynamic changes process to machinery space front cross rail, therefore, need the Joint strenght promoting machinery space front cross rail crossbeam assembly and left and right wheel cover shock absorber bearing assembly, and can not make to interfere or clearance issues in the upper part process of crossbeam assembly welding.
Summary of the invention
The purpose of this utility model proposes a kind ofly to ensure the machinery space front cross beam structure that the load of Joint strenght and left and right wheel cover shock absorber bearing assembly is effectively transmitted.
According to the machinery space front cross beam structure that the utility model provides, comprise cross-beam body, be connected to the connection bracket at cross-beam body two ends, wheel cover assembly, extension plate, described connection bracket, wheel cover assembly, extension plate is all symmetrical set the two ends at cross-beam body, described connection bracket has first connecting portion be connected with cross-beam body, the opposite side of the relatively described cross-beam body of described first connecting portion is provided with stair-stepping second connecting portion, described second connecting portion is connected with described wheel cover assembly, the side of described second connecting portion is provided with the 3rd connecting portion be connected with described extension plate, described extension plate is connected with wheel cover assembly.
Machinery space front cross beam structure of the present utility model, take connection bracket as link, make left and right wheel cover shock absorber bearing assembly form three by the second connecting portion of connection bracket with the 3rd connecting portion and extension plate to be connected, ensure Joint strenght, make the load of left and right wheel cover shock absorber bearing assembly transmission effectively be transmitted by cross-beam body simultaneously, reduce the cracking risk of the links such as connecting portion roof drip; By the setting of connection bracket, machinery space front cross rail assembly ensures the functional dimension of its Y-direction in welding process by welding jig, prevent machinery space front cross rail assembly from welding in part process with left and right wheel cover shock absorber bearing assembly and interfere or clearance issues.
Further, the cross section of described cross-beam body is U-lag structure, to ensure the intensity of cross-beam body.
Further, the cross sectional shape of described first connecting portion and the cross sectional shape adaptation of described cross-beam body, to increase connection area as far as possible, ensure Joint strenght.
Specifically, described connection is and is welded to connect.
