In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a wheel hub bearing flange inner circle, includes the ring flange, the one end of ring flange is formed with along axial extension and supplies the rolling dabber of ball with outer flange cooperation, the other end of ring flange is formed with along axial extension and is used for the annular round platform with wheel and brake disc complex, the ring flange circumference equipartition has a plurality of connecting holes that are used for the wheel bolt to wear to establish the pressure equipment, the position that the biggest excircle department of ring flange corresponds between two adjacent connecting holes is formed with the circular arc breach.
By adopting the scheme, the circular arc notch is arranged on the flange plate, compared with a complete circular flange plate in the prior art, the flange plate with the circular arc notch can reduce certain weight, save a part of materials and achieve the purpose of light weight. And the arc notch is arranged between two adjacent connecting holes, so that the arc notch is prevented from interfering the connecting holes, and the wheel bolt can be ensured to smoothly penetrate through and be pressed in the connecting holes. The flange plate can be directly forged and formed through a forging process, the structure is simple, the processing is convenient, and the purpose of light weight is achieved.
As a further setting of the utility model, the annular round platform is provided with a plurality of arc-shaped notches along circumference.
By adopting the scheme, the consumption of the inner ring of the flange is further reduced, the weight of the inner ring of the flange is reduced, and the aim of light weight is fulfilled.
As a further setting of the utility model, the other end terminal surface of ring flange is provided with the annular, the annular corresponds the setting and is greater than the aperture of connecting hole in connecting hole department and the radial trough width of annular.
By adopting the scheme, the consumption of the inner ring of the flange is further reduced, the weight of the inner ring of the flange is reduced, and the aim of light weight is fulfilled.
As a further arrangement of the present invention, the arc end of the arc notch and the outer diameter end of the ring groove are arranged in a cross manner.
By adopting the scheme, on the premise of not interfering the connecting hole, the size of the arc notch is increased as much as possible, the weight reduction weight is improved, the quality of the flange inner ring is lighter, and the flange inner ring is attractive in appearance.
As a further setting of the utility model, the position that the other end terminal surface of ring flange corresponds annular round platform is inwards sunken to be formed with the hole.
Adopt above-mentioned scheme, through setting up the hole, can further lighten the weight of flange inner circle on the one hand for the flange inner circle is lightweight more, and on the other hand, the car of being convenient for adds man-hour, and usable instrument top is established and is fixed a position and the tight fixed in top in the hole, thereby conveniently drives the flange inner circle and rotates, the processing of being convenient for.
The present invention will be further described with reference to the accompanying drawings.
