Abstract
The invention provides a special-shaped assembly bolt. The bolt comprises a screw rod part and a flange part, a section of guide rod part arranged at the lower end of the screw rod part, and a boss part arranged at the upper part of the screw rod part, wherein diameters of the guide rod part and the screw rod part are less than those of the boss part and a bolt hole, and the diameter of the boss part is guaranteed to be in interference fit with the bolt hole. Because the front end of the bolt structure is provided with the guide rod part with the diameter of less than that of the screw part, the bolt structure is convenient for rear shaft assembly; and the rear end of the bolt is provided with a section of boss part, the fit clearance between a bolt hole and the bolt can be reduced when a bolt hole of a rear shaft assembly bracket is designed, so that the abnormal sound problem after assembly is effectively prevented.
Description
Technical field
The present invention relates to bolt, be specifically related to a kind of special-shaped construction bolt.
Background technique
Automobile industry twist beam type rear axle construction bolt is generally the flange plate construction bolt of general expression at present, and is as shown in Figure 1, and its structure comprises screw part 1 and flange part 2, because this structural bolts does not have guide rod, is difficult for assembling when in the workshop rear axle being installed.Assembling for the ease of rear axle; There is technology to design rear axle mounting bracket bolt hole than the big several millimeters of the diameter of bolt; Though this fit system is beneficial to the assembling of bolt; But because there are big gap in bolt and mounting hole, when crossing deceleration strip, be easy to generate the impact abnormal sound, influence user's satisfaction.
Summary of the invention
The purpose of this invention is to provide a kind of special-shaped construction bolt structure, the difficult installation that exists with effective solution general expression bolt and back abnormal sound problem is installed.
Technological scheme of the present invention is following:
A kind of special-shaped construction bolt, it comprises screw part and flange part.Further, also have one section guide rod portion, also have one section boss part in the upper end of screw part in the lower end of screw part; The diameter of said guide rod portion and screw part is littler than the diameter of boss part and bolt hole, the diameter of said boss part to guarantee with bolt hole be interference fit relation.
The diameter of said guide rod portion is littler than the diameter of screw part.
The present invention compares with existing technology and has the following advantages:
This bolt arrangement can make things convenient for the rear axle assembling because front end has the guide rod portion of one section diameter less than screw part; There is one section boss part the rear end in addition, when design rear axle mounting bracket bolt hole, can reduce the matching gap of this hole and bolt, effectively prevents to assemble the abnormal sound problem that the back exists.
Description of drawings
Fig. 1 is the structural representation of existing bolt;
Fig. 2 is the structural representation of this bolt.
Embodiment
Referring to figure, 2, this heterotypic bolt structure mainly is made up of the guide rod portion 3 of front end, middle screw part 1, boss part 4 and rear end flange part 2.The diameter of guide rod portion 1 and screw part 2 is littler than the diameter of boss part 3 and bolt hole, the diameter of boss part 3 to guarantee with bolt hole be the interference fit relation.Because guide rod portion 1 is all little than boss part 3 diameters with screw part 2 diameters, when assembling, pass rear axle mounting bracket bolt hole easily; After the rear axle assembled; Boss part 3 and rear axle mounting bracket bolt hole interference fit, the gap is very little, has prevented the impact abnormal sound that car load produces when crossing deceleration strip; Flange part 4 has increased the fitting area with mounting bracket, has effectively prevented problems such as bolt torsion becomes flexible.
