Embodiment
Below in conjunction with embodiment, the utility model is elaborated.
The automobile four-wheel that Fig. 2 provides for the utility model embodiment is located the structural representation of adjusting part, and the automobile four-wheel that Fig. 3 provides for the utility model embodiment is located the structural representation of eccentric bolt in adjusting part.
The utility model embodiment provides a kind of automobile four-wheel location adjusting part, comprise eccentric bolt 1, eccentric washer 2 and nut 3, described eccentric bolt 1 comprises hex head bolt head 12, eccentric flange dish 11 and screw rod, described hex head bolt head 12 is positioned at one end of described screw rod, described eccentric flange dish 11 is fixedly connected with described hex head bolt head 12, and described eccentric washer 2 and described nut 3 are fixed on the other end of described screw rod.Nut 3 is preferably countersunk nut, fit tolerance that can free size.
Wherein: described screw rod, near described eccentric flange dish 11, is divided into the first polished rod 132, the second polished rod 133, the 3rd polished rod 135 and threaded stem 134 successively; Described the first polished rod 132 is identical with the outside dimension of described the 3rd polished rod 135; The outside dimension of described the second polished rod 133 is less than the outside dimension of described the first polished rod 132, and in the present embodiment, the external diameter of the second polished rod 133 is than the little 2mm of the external diameter of the first polished rod 132; The outside dimension of described the second polished rod 133 is less than the outside dimension of described threaded stem 134; The outer wall of described the 3rd polished rod 135 is provided with fluting 131, and this fluting 131 can be milling moulding, can be also cold-heading molding, and the section that makes described the 3rd polished rod 135 is the circle that lacks string.The setting of fluting 131 can limit the rotation of eccentric washer 2, also plays location and shear-stable effect simultaneously.
As shown in Figures 2 and 3, the first polished rod 132 is identical with the outside dimension of the 3rd polished rod 135, and the two is all thicker polished rods.In the time that the eccentric flange dish 11 of eccentric bolt 1 is limited in the locating slot of Rear secondary frame for vehicle, eccentric flange dish 11 can only rotate, the first polished rod 132 location of matching with the positioning hole of offering on rear overhang pull bar.While adjusting tire angle, the first polished rod 132 prizes rear overhang pull bar by positioning hole and moves.
Preferably, compare with the 3rd polished rod 135 with the first polished rod 132, the length of the second polished rod 133 is greater than the length of the first polished rod 132 and the 3rd polished rod 135, can be referred to as elongate rod at this.Elongate rod is positioned at the weakest position of whole screw rod, i.e. the surrender part of bolt.When to bolt tightening, the plastic deformation of bolt just occurs in this position., by longer thin bar design, while making to tighten, can have between longer yield region meanwhile, can meet and be repeatedly used.In addition, the outside dimension of elongate rod is less than the outside dimension of threaded stem 134, makes the sectional area of elongate rod be less than the sectional area of helical thread portion, makes elongate rod become the weakest position on whole screw rod.
On the basis of above-described embodiment, threaded stem 134 parts are set as far as possible for tooth is apart from less closely-pitched.In the present embodiment, the worm tooth on threaded stem 134 is apart from being 1.5mm, and closely-pitched, for coarse thread, because the area of the suffered stress of helical thread portion can be large, therefore can improve the intensity at screw thread position.Improve because closely-pitched makes the intensity of threaded stem 134, what therefore the external diameter of elongate rod part just can design is larger, thereby improves the intensity of elongate rod.
View after the automobile four-wheel location adjusting part that Fig. 4 provides for the utility model embodiment is assembled, the assembling mode of adjusting part as shown in Figure 4, when needs are during compared with high-clamping force, can set and reasonably be with angled moment of torsion by test, for example, first eccentric bolt 1 is tightened to 100NM, after all parts are all fitted to together, then rotate 60 degree, the process of corner, nut 3 depends on tooth distance with respect to the kinematic relation of eccentric bolt 1, is therefore easier to control.
In the time using this adjusting part, first eccentric bolt 1 is fit in the locating slot of Rear secondary frame for vehicle and the positioning hole of rear overhang pull bar, put eccentric washer 2 and nut 3 from the other end of eccentric bolt 1, four-wheel location is adjusted.Then use electric torque rifle, according to the angled moment of torsion of enforcement of regulations band of a setting, thereby eccentric bolt can be screwed to yield point.It is tighter that the automobile four-wheel location adjusting part that the present embodiment provides can be twisted than the adjusting part of prior art, its reason is: 1, on the screw rod of eccentric bolt of the prior art, offer groove, therefore intensity is lower, and in the adjusting part that the present embodiment provides, the helical thread portion of eccentric bolt is arranged on threaded stem, although elongate rod part intensity a little less than, stress is not concentrated, so that the intensity of whole eccentric bolt is wanted is high.2, in the adjusting part that the present embodiment provides, the plastic deformation of eccentric bolt occurs in elongate rod part, so possess the condition that tightens to plastic range, that can twist is tighter.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of the each embodiment's technological scheme of the utility model.
