Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
According to an aspect of the utility model embodiment, provide mounting bracket under a kind of rear shock absorber, be applicable to the vehicle of integral type rear axle, as shown in Figure 1, be welded by stay bearing plate 1, brace panel 2, pivot pin bolt 3 and pad 4, wherein:
Described stay bearing plate 1 is U-shaped structure, comprises the first side plate 100, second side plate 101 and the 3rd side plate 102.First side plate 100 and the 3rd side plate 102 are oppositely arranged, second side plate 101 is between the first side plate 100 and the 3rd side plate 102, be connected with the first side plate 100 and the 3rd side plate 102 arc respectively, thus, the stay bearing plate 1 be made up of the first side plate 100, second side plate 101 and the 3rd side plate 102 is a U-shaped structure.
As shown in Figure 2, the middle part of the second side plate 101 offers the first through hole, and the end face of the first end of the second side plate 101 comprises multiple transition arc 103.When the lower lining of rear shock absorber produces excessive deformation, the interference problem of easy generation rear shock absorber oil drum lower portion and mounting bracket, therefore, in order to avoid producing interference problem, the end face of first end is designed to multiple transition arc 103, and the design of multiple transition arc 103 has taken into full account the path of motion of rear shock absorber under each service condition, ensure that the minimum safe gap of rear shock absorber oil drum lower end and mounting bracket, and don't damaged the rigidity of whole support.
In addition, the second end of the first side plate 100 is connected with rear axle, the end surface shape of the second end and the mating shapes of rear axle; Being connected with rear axle of 3rd end of the 3rd side plate 102, the end surface shape of the 3rd end and the mating shapes of rear axle, wherein, the second end and the 3rd end homonymy, first end and the second end, the 3rd end homonymy.When being welded in rear axle by mounting bracket, only need the second end and the 3rd end to carry out welding with rear axle, conveniently, welding process more easily realizes for welding, location.
Brace panel 2 is positioned at the opening part of stay bearing plate 1U type structure, is oppositely arranged with the second side plate 101, and brace panel 2 is fixedly connected with the 3rd side plate 102 with the first side plate 100 respectively, thus forms a square structure in stay bearing plate 1, adds the stability of mounting bracket.
Pivot pin bolt 3 is connected with shock absorber, and the first end of pivot pin bolt 3 is through the first through hole, and be welded on brace panel 2, the second end of pivot pin bolt 3 exposes to stay bearing plate 1.Wherein, second end of pivot pin bolt 3 comprises the first connecting portion 301 and the second connecting portion 302, described first connecting portion 301 is less than the radius of the second connecting portion 302 near the radius of the second side plate 101, first connecting portion 301 away from the second side plate 101, second connecting portion 302.
The middle part of pad 4 offers the second through hole, and pad 4, by second end of the second through hole through pivot pin bolt 3, is welded on the second side plate 101.Pad 4 pairs of stay bearing plates 1 and pin bolt have welded booster action, meanwhile, can will install hard spot outwards movement again under rear shock absorber, are convenient to arrange rear shock absorber.
Preferably, stay bearing plate 1 is that punching press is one-body molded, and manufacturing process is simple.
Preferably, the second connecting portion 302 is set in the lining of described rear shock absorber, and the axial length of the second connecting portion 302 is identical with the axial length of described lining, to make under rear shock absorber attachment point when assembling nut, ensures that lining there will not be gross distortion.
In prior art, wheel is when bearing excessive lateral loading, rear axle can laterally power direction motion, now rear shock absorber also can swing along its axis direction, if the support of open-type, when side force is excessive, the windup-degree of lining are limited, shock absorber can only be allowed to bear excessive side force, be easy to cause shock absorber to damage.And mounting bracket under the rear shock absorber that the utility model embodiment provides, side force is offset in distortion by lining, and when side force is excessive, lining can swing by relative pin bolt, thus the angle making swing is larger, shock absorber can not be made excessive and damaged at windup-degree.
The utility model implements mounting bracket under the rear shock absorber provided, structure is simple, reliable design, easily realize with the welding process of rear axle, the attaching/detaching of shock absorber is convenient, only needs lining under shock absorber to pierce into pin bolt, put pad and urgent nut again and can realize assembling (otherwise dismounting), arrange can operational space large, the ability of certain side force can either be born, effectively can avoid the interference problem etc. with rear shock absorber oil drum bottom again.
According to another aspect of the present utility model, provide a kind of automobile, comprise mounting bracket under rear shock absorber as above.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
