Abstract

The invention provides an integrated ABS sensor automobile hub bearing unit. The integrated ABS sensor automobile hub bearing unit is characterized in that an inner ring is fastened on the outer circle of the end part of an internal flange plate; a first raceway is arranged between the inner ring of and an external flange plate; a first magnetic cage is mounted in the first raceway; a first rolling body is mounted in a pocket of a first magnetic cage; an internal side sealing ring is arranged between the inner ring and the external flange plate; a second raceway is arranged between the external circular surface of the other end of the internal flange plate and the internal circular surface of the external flange plate; a second magnetic cage is mounted in the second raceway; a second rolling body is mounted in a pocket of a second magnetic cage; an external side sealing ring is arranged at root parts of the internal flange plate and the external flange plate; a gear ring is arranged ina position, between the first rolling body and the second rolling body, on the external circular surface of the internal flange plate; a three-chip ABS sensor is inserted in a circular through hole formed in the middle part of the external flange plate; and a three-chip ABS sensor fixing ring is fixed on the external flange plate by using an internal hexagonal bolt.

Description

technical field [0001] The invention relates to the technical field of automobile hub bearing units, in particular to an integrated ABS sensor automobile hub bearing unit. Background technique [0002] The existing hub bearing unit has ABS signal output, and its structure is composed of an ABS sensor, a ring gear, an outer flange, an inner ring, two rows of rolling elements, two cages, an inner flange, and Corresponding number of sealing rings and knurled bolts. The ABS sensor is installed on the outer flange, the ring gear is installed on the inner flange, and the axial position of the ABS sensor is directly above the ring gear. The inner flange drives the ring gear to rotate together to realize the signal output measurement of the ABS sensor. However, the ABS sensor still has the disadvantage that the induction signal is output through the speed of the ring gear on the inner flange connected to the wheel, and the speed of the two rows of rolling elements cannot be monito...
