The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
In the utility model, in the situation that do not do opposite explanation, the upper and lower, left and right of the noun of locality of use shown in " upper and lower, left and right " typically refer to reference to the accompanying drawings; " inside and outside " refers to inside and outside with respect to the profile of each parts itself.
According to an aspect of the present utility model, a kind of bolt fastening structure is provided, comprise bolt 4, nut 6 and the first attaching parts and the second attaching parts, wherein, bolt 4 passes the through hole on the first attaching parts and the second attaching parts and passes through nut 6 fastening, and has the sleeve 5 that is set on the bolt 4 between the second attaching parts and the nut 6.Wherein, the bolt grade of bolt 4 is preferably more than 10.9, and satisfying the high strength demand, but the utility model is not limited to this.
As mentioned above, owing to having the sleeve 5 that is set on the bolt 4 between the second attaching parts and the nut 6, length and the guidance quality of bolt 4 have so been increased, at this moment, because the length of bolt 4 increases, its elasticity has also obtained corresponding increase, simultaneously, the bolt 4 that length increases is equivalent to a spring, the spring performance of bolt 4 can well compensate for the variation of predetermincd tension, thereby make the variation fluctuation of predetermincd tension weakened, therefore greatly strengthened locking property and the reliability of this bolt fastening structure.
As shown in Figure 2, for the length that guarantees bolt 4 is enough to make it have certain spring performance or makes described spring performance can produce the effect that due compensation predetermincd tension changes, preferably, the length E of the screw rod of bolt 4 is more than or equal to 80mm, the length D of sleeve 5 is more than or equal to 30mm, but the utility model is not limited to this, that is to say, the length D of the length E of screw rod and sleeve 5 can suitably reduce, and needs only so that the actual required Joint strenght that the spring performance that bolt 4 shows can satisfy under the different application condition requires.
In addition, in order further to improve the locking property of bolt fastening structure, be preferably double nut according to the nut 6 of embodiment of the present utility model, but the utility model is not limited to this.
With reference to figure 2, according to embodiment of the present utility model, preferably, the first attaching parts be connected attaching parts and be respectively auxiliary girder and connect otic placode 2 and be connected otic placode 3 with chassis side rail, auxiliary girder connect otic placode 2 is connected with chassis side rail otic placode 3 be separately positioned on the compartment auxiliary girder 1 with chassis side rail 7 on, and auxiliary girder connection otic placode 2 is connected otic placode 3 and comprises respectively the first relative connecting portion 8 and the second connecting portion 9 with chassis side rail, bolt 4 passes the first connecting portion 8 and the second connecting portion 9 and fastening by nut 6, and has between the second connecting portion 9 and the described nut 6 and be set on the described sleeve 5 of stating on the bolt 4.Do the time spent at static load, because bolt 4 is connected under the effect of predetermincd tension, the friction force that produces between nut 6 and bolt cap and bearing surface is connected bolt to have certain anti-loose ability; Vehicle in the process of moving, because chassis side rail 7 is being hit, during the factor affecting such as vibration or variable load, the predetermincd tension of bolt 4 will change, at this moment, the friction drag that prevents thread looseness may reduce or instantaneous disappearance, screw thread probably loses self-locking and gets loose, yet, owing to having the sleeve that is set on the bolt 4 between the second attaching parts and the nut 6, so increased length and the guidance quality of bolt 4, at this moment, the bolt 4 of lengthening is equivalent to a spring, the spring performance of this bolt 4 so that the locking property of this bolt fastening structure and reliability strengthen, thereby so that the compartment be connected safely and reliably with chassis side rail 7.Here need to prove, the utility model has only provided the embodiment that described bolt fastening structure is applied to connect automobile bodies and vehicle frame, but the utility model is not limited to this.
For the dismounting that is installed on of conveniently processing and making things convenient for bolt 4, as shown in Figure 2, preferably, the first connecting portion 8 and the second connecting portion 9 parallel to each other and spaces, here, the spacing between the first connecting portion 8 and the second connecting portion 9 is not particularly limited, because the existence of sleeve 5 can make the length of bolt 4 increase indirectly, so the spacing between the first connecting portion 8 and the second connecting portion 9 can even be less value less than 10mm, and the utility model is not limited to this.
According to another aspect of the present utility model, the utility model also provides a kind of vehicle, wherein, is connected by the bolt fastening structure described in the technique scheme between the compartment of described vehicle and the vehicle frame.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in the above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment in reconcilable situation, can make up by any suitable mode.For fear of unnecessary repetition, the utility model is to the no longer separately explanation of various possible array modes.
In addition, also can carry out combination in any between the various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
