Abstract
A hub bearing unit with differentiated inner holes. The automobile hub bearing unit mainly solves the problem that two inner rings of an existing automobile hub bearing unit are installed in an outer flange in parallel and are troublesome in assembly. The method is characterized in that: the diameter of the first inner hole is smaller than that of the first outer hole, and a first inner ring is arranged in the first inner hole; the second stepped hole mechanism comprises a second outer hole and a second inner hole, the diameter of the second inner hole is smaller than that of the second outer hole, and a second inner ring is arranged in the second inner hole; the inner diameter of the first inner ring is smaller than that of the second inner ring. The utility model provides a wheel hub bearing unit of hole differentiation adopts the inner circle of two different internal diameters and installs at the both ends of ring flange hole, is convenient for pack into on the one hand, and on the other hand is the step shaft rather than the complex when the loading, can restrict wheel hub bearing unit and prolong the motion or the trend of motion of axis direction, reduces the impact to lock nut, promotes working life.

Drawings
Fig. 1 is a schematic cross-sectional view of an embodiment of the present invention.
Fig. 2 is a schematic cross-sectional view of another embodiment of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, a hub bearing unit with differentiated inner holes comprises an outer flange 1, wherein the outer flange 1 is axially provided with a through hole 2, one end of the through hole is provided with a first stepped hole mechanism, the other end of the through hole is provided with a second stepped hole structure, the first stepped hole mechanism comprises a first outer hole 31 and a first inner hole 32, the diameter of the first inner hole is smaller than that of the first outer hole, and a first inner ring 321 is arranged in the first inner hole; the second stepped hole mechanism comprises a second outer hole 41 and a second inner hole 42, the diameter of the second inner hole is smaller than that of the second outer hole, and a second inner ring 421 is arranged in the second inner hole; the inner diameter of the first inner ring is smaller than that of the second inner ring. Adopt the inner circle of two different internal diameters and install at the both ends of ring flange hole, be convenient for on the one hand pack into, on the other hand, when the loading with its complex be the step shaft (because the internal diameter of two inner circles is different), can restrict the motion or the motion trend of wheel hub bearing unit along the axis direction, reduce the impact to lock nut, promote working life.
In the present invention, as shown in the figure, the through hole inner wall and the first inner ring outer wall are provided with a first bearing 51 therebetween.
In the present invention, as shown in the figure, the through hole inner wall and the second inner ring outer wall are provided with a second bearing 52 therebetween.
