Description
Technical Field
The utility model relates to the field of automobile hub screws, in particular to an automobile hub screw.
Background
As shown in the attached figure 6 of the specification, the hub screw of the first generation product and the hub screw of the existing popular product are provided with the section lightening holes which are strip-shaped holes or kidney-shaped holes. The hub screw is basically not problematic when applied to a common automobile, because the requirement on the pretightening force of the hub screw of the common automobile is not high. However, the hub screw pre-tightening force required by racing is easy to be broken when the screw is used, as shown in the figure. And there has been a number of dealer feedbacks. The racing car is short in repair period, a hub screw needs to be screwed, and the influence of fatigue strength is caused, so that the service life of the racing car is short. The analysis is caused by insufficient mechanical design of the lightening hole structure, so that structural improvement is needed.
Moreover, in order to screw out the hub screw more quickly, when the hub screw is about to be screwed out, the hub screw needs to be pinched by a hand to be screwed, and the hub screw is screwed out slowly by using a tool when the hub screw is about to be screwed out, but the gloves worn by the user are slippery due to a lot of oil stains, so the hub screw is easy to slip when being screwed.
Finally, the existing hub screw does not have a spare force application point, and the hub screw cannot be unscrewed when no proper wrench is available on site, so that a hub screw with a spare force application point is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an automobile hub screw, which improves the structural mechanical design of lightening holes, increases the bearing strength of torque load, has better mechanical property through tests, and prolongs the service life of products; the anti-slip threads are arranged, so that the hub screw is not easy to slip when being manually screwed; a unique spare force application screwing point is designed, and the hub screw can be unscrewed even if a proper wrench is not available on site.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
a head end of the hub screw is a threaded end; hollow holes are formed in the middle end of the hub screw, and reinforcing ribs are reserved between every two adjacent hollow holes; the tail end of the hub screw is a columnar hand-screwing end.
And a hexagonal hollow structure similar to a honeycomb structure is formed between the hollow holes and the reinforcing ribs.
A plurality of triangular hollow structures are formed between the hollow holes and the reinforcing ribs.
And the included angle of the hexagonal hollow structure and the included angle of the triangular hollow structure are rounded off to form a smooth curve transition processing structure.
The most tail end of the columnar hand screwing end is provided with anti-skid lines.
The column hand is twisted and is held and be close to the well end one side annular array of wheel hub screw and be equipped with a plurality of jacks.
Compared with the prior art, the utility model has the beneficial effects that:
this product automobile wheel hub screw has improved the structural mechanics design of lightening hole, the honeycomb structure has outstanding geometric mechanics performance, this design designs into hexagon hollow out construction with the fretwork hole, triangle-shaped hollow out construction, and leave the strengthening rib strip between the adjacent fretwork hole, and the equal radius angle of fretwork hole contained angle department, form smooth curve transition processing structure, whole structural mechanics design is more reasonable, structural strength is very high, increase its torque load's bearing strength, there is more mechanical properties through the experiment, weight is very light again, the service life of product is improved.
The anti-skidding threads are arranged at the tail end of the columnar hand-screwing end, so that the friction force is increased and the wheel hub screw is not easy to skid when the wheel hub screw is screwed manually; the column hand is twisted one side ring array and is equipped with a plurality of jacks near the middle-end one side of wheel hub screw, designs unique reserve power and twist the point, when the scene does not have suitable spanner, alternates at jack department and inserts the post and also can twist off the wheel hub screw as the spanner.

Detailed Description
The utility model will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.
Example 1:
the utility model relates to an automobile hub screw, wherein the head end of the hub screw is a threaded end 1; the thread end 1 is a conical surface matched with the hub. Hollow holes 3 are formed in the middle end 2 of the hub screw, the hollow holes 3 serve as lightening holes, and reinforcing ribs 4 are reserved between every two adjacent hollow holes 3; a hexagonal hollow structure similar to a honeycomb structure is formed between the hollow holes 3 and the reinforcing ribs 4.
