The technical scheme that its technical matters that solves the utility model adopts is: a kind of High Performance lightweight hub-bearing unit, comprise flange wheel hub, flange plate outer ring, inner ring, biserial rolling body, retainer and magnetic encoder, the flange wheel hub comprises flange end face and hub spindle, and the biserial rolling body lays respectively among hub spindle root raceway and the inner ring raceway; Be provided with in the inboard of described flange plate outer ring respectively and the corresponding parallel biserial cup raceway side by side of hub spindle root raceway and inner ring raceway, the rolling body outside that is installed between cup raceway and hub spindle root raceway and the inner ring raceway is provided with retainer, and the inner ring outside is provided with the flange lug boss that adapts with the rolling body sphere; Magnetic encoder is arranged sintering on inner ring shaft shoulder face according to gear shaping shape.
Described flange end face is a plum blossom shape structure, and flange end face endoporus is an arcuate structure.
Be provided with step on described hub spindle, the terminal surface of hub spindle is arranged to crimping, and this crimping and the inner ring end face outside are for realizing the end face axle riveted construction of axial location.
The inboard step position with hub spindle of described inner ring is an interference fit, and an end face of inner ring is resisted against hub spindle shaft shoulder face.
Be provided with step in the described inner ring rib boss outside.
Described magnetic encoder is multistage magnetic rubber, and the distance of magnetic encoder inner ring surface and inner ring step surface is 1.0-1.5mm.
Be provided with low friction moment integral seal circle between the outside of described inner ring and the inboard of flange plate outer ring.
Be provided with the seal ring of forming by garter spring seal ring and single lip seal circle between the inboard of described hub spindle and flange plate outer ring.
The beneficial effects of the utility model are: the structure that adopts inner ring sintering magnetic encoder, eliminated the instability of the axial and radial position of the relative hub-bearing unit of magnetic encoder, reduce the fluctuation of the relative abs sensor of magnetic encoder position, improved the reliability of ABS work; The flange end face of flange wheel hub adopts plum blossom shape structure and flange end face endoporus to adopt the arcuate structure that is similar to sphere, has alleviated the total weight of parts, has reduced fuel oil consumption, reaches purpose of energy saving.
