Detailed description of the invention
For the technical characterstic of this programme can be clearly described, below by detailed description of the invention, and combining its accompanying drawing, the utility model is elaborated.
As shown in FIG. 1 to 3, this utility model includes base 1 and for installing the bend pipe 2 of mud guard.Base 1 includes the pedestal 101 being connected with vehicle frame and the connecting portion 102 being connected with bend pipe 2, wall thickness α near the bend pipe end of connecting portion 102 is more than the bend pipe wall thickness β away from connecting portion 102, and seamlessly transits to the bend pipe wall thickness β away from connecting portion 102 near the wall thickness α of the bend pipe end of connecting portion 102.Bend pipe 2 uses friction welding (FW) or electron beam weldering to be connected with connecting portion 102.Connecting portion 102 is positive round cone, and the middle part of positive round cone is provided with the first through hole 3, and the first through hole 3 is inverted cone-shaped.It is positioned at the position outside connecting portion 102 on pedestal 101 and is provided with bolt hole 4.Bolt hole 4 is two, lays respectively on the pedestal 101 of connecting portion 102 both sides.Being positioned on pedestal 101 at bolt hole 4 and be provided with boss 5, boss 5 is arranged with connecting portion 102 homonymy.The bottom of pedestal 101 is provided with scrobicula step 6.On pedestal 101, the position corresponding to the first through hole 3 is provided with the second through hole 7, and the second through hole 7 is connected with the first through hole 3.It is provided with reinforcement 8 in second through hole 7.
This utility model bend pipe 2 uses friction welding (FW) or electron beam weldering to be connected with connecting portion 102, effectively prevent weld seam oxidation, oozes the traditional welding defects such as slag, improves intensity and the reliability of weld seam.It addition, weld seam flanging remains weld seam step 9 high for 1mm to increase weld strength in removal process.
For solving friction welding (FW) or electron beam weldering mud guard fixing support assembly weld strength and the conflicting problem of lightweight, bend pipe 2 end welded with connecting portion 102 phase uses the most isometrical change wall construction, the i.e. wall thickness α near the bend pipe end of connecting portion 102 is more than the bend pipe wall thickness β away from connecting portion 102, and seamlessly transits to the bend pipe wall thickness β away from connecting portion 102 near the wall thickness α of the bend pipe end of connecting portion 102.The design of this structure not only effectively reduces the weight of mud guard fixing support assembly, is also effectively increased bead contact area and weld strength simultaneously.Preferably, being 5mm near the wall thickness α of the bend pipe end of connecting portion 102, the bend pipe wall thickness β away from connecting portion 102 is 3mm, and compared with the bend pipe of existing 4.5mm wall thickness, single-piece loss of weight 1.6kg, loss of weight ratio is up to 30%, and effect is clearly.
Connecting portion 102 is positive round cone, and the middle part of positive round cone is provided with the first through hole 3, and the first through hole 3 is inverted cone-shaped, thus forms the connecting portion not waiting wall.Connecting portion 102 uses the structure of wall thickness gradual change from bottom to top, not only reduces mud guard fixing support assembly weight, also reduces the bottom force-bearing situation of connecting portion 102 simultaneously, it is to avoid the bottom stress concentration problem of connecting portion 102.
It is positioned at the position outside connecting portion 102 on pedestal 101 and is provided with bolt hole 4, it is simple to pedestal 101 is connected with vehicle frame.Preferably, bolt hole 4 is two, lays respectively on the pedestal 101 of connecting portion 102 both sides, so decreases pedestal area in the case of ensureing pedestal 101 bonding strength, it is simple to the layout of car load as far as possible.
Being positioned on pedestal 101 at bolt hole 4 and be provided with boss 5, boss 5 is arranged with connecting portion 102 homonymy.The design of boss 5, adds the connecting length of bolt, is prevented effectively from bolt and gets loose and breakage problem.
The bottom of pedestal 101 is provided with scrobicula step 6.The design of this structure not only reduces base 1 weight, decreases pedestal 101 bottom surface amount of machining simultaneously.
On pedestal 101, the position corresponding to the first through hole 3 is provided with the second through hole 7, and the second through hole 7 is connected with the first through hole 3.The design of this structure reduces the weight of base 1.
It is provided with reinforcement 8, and the design of scrobicula step 6 in second through hole 7, not only increases the intensity bottom pedestal 101, also effectively prevent rainwater and invade the hidden danger causing weld cracking at corner bead for a long time.
This utility model is made up of base 1 and bend pipe 2, simple in construction, and friction welding (FW) or electron beam welding control technique the most simply, and welding efficiency is high.
Mud guard fixing support assembly versatility of the present utility model is higher, it is simple to promote, and i.e. for different automobile types and frame width, can realize sharing by the length and angle changing bend pipe, have the highest versatility.
Above-mentioned detailed description of the invention cannot function as the restriction to this utility model protection domain, and to those of ordinary skill in the art, any alternate modification or the conversion of being made this utility model embodiment all fall within protection domain of the present utility model.
This utility model does not describes part in detail, is the known technology of those skilled in the art of the present technique.
