Specific implementation mode
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
As shown in Figure 1 and Figure 2, the embodiment of the present invention provides a kind of damper fixing bracket, including：
Rack body and the bolt suspending head 1 being set on the rack body, vehicle shock absorber assembly pass through the bolt
Suspending head 1 is fixedly connected with the rack body；
The rack body includes：
The end face 21 of first support plate 2, the first end of first support plate 2 is cambered surface；And
The second support plate 3 being oppositely arranged with first support plate 2, the end face of the first end of second support plate 3
31 be cambered surface；Wherein, the cambered surface can fit with the outer surface of the bridge tube of Automobile drive axle assembly, the cambered surface with it is described
The outer surface of bridge tube is by being welded to connect.
In the above embodiment of the present invention, as shown in Figure 1, the entire end face of the first end of the first support plate is cambered surface,
The entire end face of the first end of second support plate is also cambered surface, which can be arranged in Automobile drive axle assembly just
The outer surface of bridge tube, and being fixedly connected with the outer surface of the bridge tube by welding, therefore the cambered surface is weld seam end face, i.e., first
The end face 21 of the first end of support plate 2 is the first weld seam end face, and the end face 31 of the first end of the second support plate 3 is the second weld seam end
Face；The rack body is welded to connect by the first weld seam end face and the second weld seam end face with bridge tube, then the weldering of the first weld seam end face
Seam is sufficiently wide with the weld seam of the second weld seam end face, and the molten depth of weld is also enough, enhances the weld strength of holder.
To sum up, according to the present invention embodiment the case where, be computed veritification, the first support plate 2, the second support plate 3 exist
Stress concentration point, i.e., damper fixing rack structure provided in an embodiment of the present invention is under limit pavement state, on the left of holder originally
Body stress maximum value reaches 295MPa (yield limit 229MPa) or more, this body stress maximum value reaches 295MPa on the right side of holder
More than (yield limit 229MPa), so damper fixing bracket provided in an embodiment of the present invention is not in intensity, weld seam
Insufficient (incomplete) penetration causes it to there are problems that fatigue crack risk under automobile limit driving cycle.
Specifically, in the above embodiment of the present invention, the lower longitudinal tie of second support plate 3 and Automobile drive axle assembly
Holder abuts, and by being welded to connect.
In the embodiment of the present invention, the lower longitudinal tie holder of the second support plate 3 and Automobile drive axle assembly by being welded to connect,
So that damper fixing bracket is fixedly connected with lower longitudinal tie holder, Fig. 2 shows the second support plates 3 and lower longitudinal tie holder
Weld seam end face 32, since the second support plate 3 and the bonding area of lower longitudinal tie holder are enough big, admittedly there is no the wind of fatigue crack
Danger.

Connect the reinforcing plate 5 of first support plate 2 and second support plate 3, the reinforcing plate 5 and the third branch
Fagging 4 is oppositely arranged.
As shown in Figure 1, the first support plate 2, the second support plate 3, third support plate 4 and reinforcing plate 5 form stable branch
Frame connecting structure ensure that the intensity, rigidity and bending-twisting ability of holder.
Further, after in order to mitigate vibration damper complement and rack body fixation, phase attrition when driving
Damage, the damper fixing bracket further include：
Gasket 6, the gasket 6 are sheathed in the bolt suspending head 1 in the third support plate 4.Gasket 6 plays isolation and delays
The effect of punching so that vibration damper complement is not directly contacted with third support plate 4, the direct abrasion for avoiding it mutual, simultaneously
The power in the driving conditions of part can be absorbed, its mutual abrasion is mitigated.
Specifically, in the above embodiment of the present invention, the rack body uses punch forming process.I.e. the damper is solid
The rack body of fixed rack is not specifically described herein by SAPH440 material plate punch formings, moulding process.
To sum up, the above embodiment of the present invention optimizes vibration damping rear and using SAPH440 material structures to weld seam end face
Device fixing rack structure had not only met self-strength requirement, but also meet matching requirements through finite element analysis, and through excessive wheel vehicle
Authentic experiments are verified, and do not occur fatigue fracture.Compared with existing fixing bracket, damper provided in an embodiment of the present invention fixes branch
Frame intensity, rigidity, bending-twisting ability significantly improve, the weld penetration of holder welding end surface, and weld strength higher is further ensured that
The reliability of supporting structure, plays good design using effect.
In order to preferably realize that above-mentioned purpose, the embodiment of the present invention also provide a kind of automobile, as shown in figure 3, including automobile
Driving axis, vehicle shock absorber assembly 7 and damper fixing bracket 8 as described above.
Specifically, the Automobile drive axle assembly includes：Automobile drive axle 9, the bridge tube being connect with the automobile drive axle 9
10, the lower longitudinal tie holder 11 being fixedly connected with the bridge tube 10；Wherein,
The damper fixing bracket 8 is fixedly connected with the vehicle shock absorber assembly 7, the damper fixing bracket 8
It is welded to connect with the bridge tube 10, the damper fixing bracket 8 is welded to connect with the lower longitudinal tie holder 11.
It should be noted that automobile provided in an embodiment of the present invention includes the support bracket fastened automobile of above-mentioned damper, then
The above-mentioned support bracket fastened all embodiments of damper are suitable for the automobile, and can reach same or analogous advantageous effect.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
