Description
Technical field
The present invention relates to body of a motor car, more particularly to a kind of front panel front beam bridging arrangement.
Background technology
At present, traditional vehicle front panel front beam is that an overall crossbeam is overlapped on before left and right on girder assembly, and its
Joint form is the corner joint of Y-direction, so that front panel front beam assembly is unadjustable on C/C directions.Due to big before left and right
Beam is high-strength steel with front panel front beam, and the more difficult control of corner connection lap-joint Y-direction molding surface size, it is once inclined that it overlaps Y-direction type face
Difference, may result in before left and right girder assembly in the C/C deviations of directivity, causes whole front face size bigger than normal or less than normal.
The content of the invention
In order to solve the problems of the prior art, the present invention provides a kind of front panel front beam bridging arrangement.
The present invention provides a kind of front panel front beam bridging arrangement, including front panel front beam, left front girder assembly and
Girder assembly before the right side, the left and right ends of the front panel front beam respectively with the left front girder assembly, it is right before girder assembly X
To overlap joint.
As a further improvement on the present invention, described in the thickness of girder assembly is all higher than before the left front girder assembly, the right side
The thickness of front panel front beam.
As a further improvement on the present invention, the thickness of the front panel front beam is 1.4mm.
As a further improvement on the present invention, the thickness of girder assembly is 2.0mm before the left front girder assembly, the right side.
As a further improvement on the present invention, the left and right ends of the front panel front beam are respectively equipped with bending corner connection and connect
Head, positioned at the bending corner joint in left side and the left front girder assembly X to overlap joint, positioned at the bending angle on right side
Connector with it is described it is right before girder assembly X to overlap joint.
The beneficial effects of the invention are as follows：Through the above scheme, front panel front beam is divided into front panel front beam, left front big
Beam assembly and it is right before three sections of girder assembly, Y-direction overlap joint is improved to X to overlap joint, there is controllability on C/C directions, can
The defects of girder assembly is avoided before left and right in the C/C deviations of directivity, causes whole front face size bigger than normal or less than normal.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of front panel front beam bridging arrangement of the present invention.
Fig. 2 is a kind of schematic diagrames of the X of front panel front beam bridging arrangement of the present invention to overlap joint.
Embodiment
The invention will be further described for explanation and embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 2, a kind of front panel front beam bridging arrangement, including front panel front beam 1, left front crossbeam are total
Into 2 and it is right before girder assembly 3, the left and right ends of the front panel front beam 1 respectively with the left front girder assembly 2, it is right before it is big
Beam assembly 3X to overlap joint, i.e., the left and right ends of described front panel front beam 1 respectively with the left front girder assembly 2, it is right before crossbeam
The contact surface that assembly 3 overlaps is perpendicular to horizontal plane.
As shown in Figure 1 to Figure 2, the thickness of girder assembly 3 is all higher than the front panel before the left front girder assembly 2, the right side
The thickness of front beam 1.
As shown in Figure 1 to Figure 2, the thickness of the front panel front beam 1 is 1.4mm.
As shown in Figure 1 to Figure 2, the thickness of girder assembly 3 is 2.0mm before the left front girder assembly 2, the right side.
As shown in Figure 1 to Figure 2, the left and right ends of the front panel front beam 1 are respectively equipped with bending corner joint 11, are located at
With the left front girder assembly X to overlap joint 21, the bending corner connection positioned at right side connects the bending corner joint 11 in left side
Head, to overlap joint, can also exchange setting, bending corner joint 11 is separately positioned on left front big with girder assembly X before the right side
Before beam assembly 2, the right side on girder assembly 3.
A kind of front panel front beam bridging arrangement provided by the invention, has the characteristics that：
（1）The overlap joint of the original Y-direction corner joint of girder assembly 3 before front panel front beam 1 and left front girder assembly 2, the right side
Form, has been changed to joint forms of the X to lap joint, key function dimension chain is had controllability, can effectively interrupt ruler
The transmission and accumulation of very little chain tolerance；
（2）Completely eliminate front panel front beam 1 and fill phenomenon not in place, that is, solve because its fill it is not in place caused by front panel
With front wheel housing overlap from sky amount up to 5mm problem above, three step on the overproof problem of mount point and front panel and wheel cover lap-joint rosin joint,
The quality problems of desoldering；
（3）With controllability, solve front panel front beam 1 and force after being attached to position, before caused left front girder assembly 2, the right side
Girder assembly 3 is turned-out in Y-direction type face, and causes the overproof quality problems of the chassis key point such as subframe, front overhang mount point,
Also to eliminate the potential risk of front-wheel sideslip；
（4）Tradition front panel front beam is divided into three sections, with left front girder assembly 2, it is right before girder assembly 3 weld together with left and right
Connector, very high to intensity requirement, its material thickness is designed as 2.0mm.The material thickness of interlude front beam is designed as 1.4mm, directly saves
Cost-saving also effectively alleviates car body weight up to 30%；
（5）Solve the bottleneck station of the difficult dress of front panel front beam assembly, improve productive temp, also improve the offline conjunction of new product
Lattice rate.
A kind of front panel front beam bridging arrangement provided by the invention has the beneficial effect that：
（1）Reduce the material thickness 0.6mm (1.4mm is reduced to by 2.0mm) of 1 high-strength steel of front panel front beam, directly save into
Originally up to 30%, meanwhile, directly alleviate car body weight 0.5128Kg（It is 1.2015Kg to be mitigated by 1.7143Kg）；
（2）Save because front panel front beam 1 and girder assembly 3Y before left front girder assembly 2, the right side are manually returned to interference
Repair, caused by manpower reprocess the cost that cost and rework time waste；
（3）Save because front panel front beam 1 fill it is not in place not in place to cause front panel to fill, caused by front vehicle body assembly scrap
And the material cost produced.
（4）Key point overproof problem in chassis caused by eliminating the 1 more difficult installation of front panel front beam, improves product pass
The stability of key size；
（5）The overlap joint for greatly reducing front panel and wheel cover is measured from sky, is improved Product jointing quality, is improved the offline conjunction of new product
Lattice rate.
Above content is that a further detailed description of the present invention in conjunction with specific preferred embodiments, it is impossible to is assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
