The problem that utility model has low production cost.
The technical solution of the utility model: a kind of automobile hub unit improving firmly beforehand means, including inner flange, inner flange
Axis body be arranged with outward flange, be provided with steel ball between axis body and the outward flange of inner flange；The inboard of described outward flange is provided with close
Seal, outward flange is provided with O, and the outside of outward flange is provided with seal closure；The axis body of described inner flange is additionally provided with circle road, encloses road
Inside being provided with inner ring, the end of the axis body of inner flange is provided with outstanding riveting end, and inner ring is stuck in circle road by outstanding riveting end.
In the above-mentioned automobile hub unit improving firmly beforehand means, the axis body both sides of described inner flange are respectively provided with a pair steel
Ball, is provided with keeper between homonymy steel ball, the both sides of keeper are provided with ball torr, and homonymy steel ball is respectively arranged at the ball of keeper both sides
In torr.
In the automobile hub unit of aforesaid improvement firmly beforehand means, described seal closure is arranged over sealing lid, seals lid
Inboard offset with outstanding riveting end.
Compared with prior art, this utility model uses outstanding riveter skill in the end of inner flange axis body, makes inner flange axis body
End form outstanding riveting end, make inner ring be tightly fixed to enclose in road, the assembling play of this structure, it is simply that the final utilization trip of product
Gap, will not be affected by extraneous factor and be changed.This utility model be respectively provided with in the both sides of outward flange sealing ring, O,
And seal closure, serve and prevent dust, sewage from entering interiors of products, prevent the effect that grease in product leaks simultaneously.Enter
One step ground, this utility model is also provided with keeper between steel ball, by steel ball even partition, it is ensured that bearing capacity during use
It is uniformly distributed.As can be seen here, of the present utility model being possible not only to improves fastening effect, thus improves the service life of product, peace
Full performance have also been obtained preferably guarantee；And the problem that this utility model has low production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but not as to limit of the present utility model
System.
Embodiment: a kind of automobile hub unit improving firmly beforehand means, as it is shown in figure 1, include inner flange 1, inner flange 1
Axis body 2 is arranged with outward flange 3, is provided with steel ball 4 between axis body 2 and the outward flange 3 of inner flange 1；The inboard of described outward flange 3 sets
Having sealing ring 5, outward flange 3 to be provided with O 6, the outside of outward flange 3 is provided with seal closure 7；The axis body 2 of described inner flange 1 also sets
You Quan road 8, circle is provided with inner ring 9 in road 8, and the end of inner flange 1 is provided with outstanding riveting end 10, and inner ring 9 is stuck in circle road 8 by outstanding riveting end 10
In.Axis body 2 both sides of described inner flange 1 are respectively provided with a pair steel ball 4, are provided with keeper 11 between homonymy steel ball 4, keeper 11
