Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with attached
Figure and specific embodiment are described in detail.
As shown in Figure 1 and Figure 2, the embodiment of the present invention provides a kind of vibroshock fixed support, including:
Rack body and the bolt being arranged on described rack body hang 1, and vehicle shock absorber assembly is by described
Bolt hangs 1 and fixing with described rack body is connected；
Described rack body includes:
First gripper shoe 2, the end face 21 of the first end of described first gripper shoe 2 is cambered surface；And,
The second gripper shoe 3 being oppositely arranged with described first gripper shoe 2, the first end of described second gripper shoe 3
End face 31 be cambered surface；Wherein, described cambered surface can be affixed with the outer surface of the bridge tube of Automobile drive axle assembly
Closing, the outer surface of described cambered surface and described bridge tube passes through to be welded to connect.
In the above embodiment of the present invention, as it is shown in figure 1, the whole end face of the first end of the first gripper shoe is equal
For cambered surface, the whole end face of the first end of the second gripper shoe is also cambered surface, and this cambered surface the most just can be blocked and set
In the outer surface of the bridge tube of Automobile drive axle assembly, and it is connected by welding is fixing with the outer surface of described bridge tube,
Therefore described cambered surface is weld seam end face, the end face 21 of the first end of the i.e. first gripper shoe 2 is the first weld seam end face,
The end face 31 of the first end of the second gripper shoe 3 is the second weld seam end face；This rack body passes through the first weld seam end
Face and the second weld seam end face are welded to connect with bridge tube, then the weld seam of the first weld seam end face and the second weld seam end face
Weld seam is the most sufficiently wide, and weld is molten deep enough, strengthens the weld strength of support.
To sum up, according to the situation of the embodiment of the present invention, it is computed veritifying, first gripper shoe the 2, second gripper shoe
3 all exist stress concentration point, and i.e. the vibroshock fixing rack structure of embodiment of the present invention offer is at limit road surface shape
Under state, on the left of support, this body stress maximum reaches more than 295MPa (yield limit is 229MPa), support
Right side this body stress maximum reaches more than 295MPa (yield limit is 229MPa), so the present invention is real
The vibroshock fixed support that executing example provides does not haves intensity, weld penetration is not enough, causes it in the automobile limit
The problem that there is fatigue crack risk under driving cycle.

Further, in order to strengthen the intensity of rack body, it is ensured that the reliability of support, described rack body
Also include:
Connect described first gripper shoe 2 and the reinforcing plate 5 of described second gripper shoe 3, described reinforcing plate 5 and institute
State the 3rd gripper shoe 4 to be oppositely arranged.
As it is shown in figure 1, the first gripper shoe the 2, second gripper shoe the 3, the 3rd gripper shoe 4 and reinforcing plate 5 shape
Become stable support connection structure, it is ensured that the intensity of support, rigidity and bending-twisting ability.
Further, in order to alleviate vibration damper complement and rack body fixing after, when driving
Mutually abrasion, described vibroshock fixed support also includes:
Pad 6, the bolt that described pad 6 is sheathed in described 3rd gripper shoe 4 hangs on 1.6, pad
To isolation and the effect of buffering so that vibration damper complement and the 3rd gripper shoe 4 are not directly contacted with, it is to avoid its phase
Directly abrasion between Hu, can absorb the power during part driving simultaneously, alleviate its mill each other
Damage.
Concrete, in the above embodiment of the present invention, described rack body uses punch forming process.I.e. should
The support bracket fastened rack body of vibroshock is by SAPH440 material plate punch forming, and moulding process is not made at this
Specifically describe.
To sum up, the above embodiment of the present invention butt welded seam end face is optimized rear and uses SAPH440 material structure
Vibroshock fixing rack structure, through finite element analysis, both met self-strength requirement, and met again assembling and want
Ask, and through too much wheel car load authentic experiments checking, fatigue fracture does not occurs.Compared with existing fixed support,
The vibroshock fixed support intensity of embodiment of the present invention offer, rigidity, bending-twisting ability significantly improve, support
The weld penetration of welding end surface, weld strength is higher, further ensures the reliability of supporting structure, plays
Good design using effect.
In order to preferably realize above-mentioned purpose, the embodiment of the present invention also provides for a kind of automobile, as it is shown on figure 3,
Including Automobile drive axle assembly, vehicle shock absorber assembly 7 and vibroshock fixed support 8 as above.
Concrete, described Automobile drive axle assembly includes: automobile drive axle 9 and described automobile drive axle 9 are even
The bridge tube 10 connect and the described fixing lower longitudinal tie support 11 being connected of bridge tube 10；Wherein,
Described vibroshock fixed support 8 is fixing with described vehicle shock absorber assembly 7 to be connected, and described vibroshock is solid
Fixed rack 8 is welded to connect with described bridge tube 10, described vibroshock fixed support 8 and described lower longitudinal tie support
