Integrated hub unit

The utility model discloses an integrated hub unit, which comprises an outer bearing ring integrally formed with a flange, wherein the outer bearing ring is sheathed to the outer surface of a big inner ring coaxially arranged with the outer bearing ring; the outer bearing ring is fixedly provided with an ABS (anti-skid brake system) sensor; a pulse generator is arranged between the outer end part of the big inner ring and the outer bearing ring; and the pulse generator is opposite to the induction surface of the ABS sensor. The integrated hub unit disclosed by the utility model is in an integrated integral-type design, has a signal function and an ABS function, and has the advantages of compact structure, strong anti-rust capability, stable signal, convenience in maintenance and good dustproof and sealing effects, the assembling technology is reduced due to the fact that a magnetic gear ring does not need to be assembled, the integral weight is lightened, and the cost is saved. The pulse generator is assembled between the outer end part of the big inner ring and the outer bearing ring and is not exposed out of the integrated hub unit, and the pulse generator can be prevented from being polluted.
