the utility model provides a hub bearing unit with integral type sensor, includes outer lane and inner circle, the outer lane with be equipped with the holder between the inner circle, be equipped with the rolling element on the holder, still include the sensor, the sensor includes housing and inductive head, the housing with the outer lane is connected, be equipped with the socket of an organic whole on the housing, be equipped with in the socket with the contact pin that inductive head electricity is connected.

The magnetic ring is sleeved on the outer wall of the inner ring, and at least part of the magnetic ring is arranged opposite to the induction head.

The housing and the socket are integrally injection molded.

The housing comprises a convex ring, a clamping ring made of metal materials is arranged on the convex ring, and the circumferential outer wall of the clamping ring is contacted with the circumferential inner wall of the outer ring.

The convex ring is provided with a flange on the circumferential outer wall, and the flange covers the front end face of the outer ring.

The housing is made of engineering plastic.

The rolling element is a steel ball.

The beneficial effects of the utility model are as follows: the utility model provides a hub bearing unit with an integrated sensor, wherein a plug of the sensor and a shell are made into an integrated structure, so that the generation of a connecting gap is avoided, the air tightness of a product can be improved, the cost can be reduced, and the benefit is improved.
