Device capable of detecting the rotational speed of two elements in relative such as the support elements of a vehicle wheel, in particular the rings of the roller bearing for the support the vehicle wheel, characterized in that an initial deflector or ring integral with the rotating ring of the bearing carries twin magnetized rings with pairs of poles of opposite sign, between which a magnetic sensor carried by a second deflector or support integral with the fixed ring of the bearing being is operatively inserted, the magnetic sensor being located between the n polar expansions, the number of which conforms to the pairs of opposing poles of twin magnetized rings.

Device for detecting the relative rotational speed of two elements in a

A device enabling the revolutionary speed to be measured between two parts in relative rotation such as the supports of a vehicle wheel and in particular between rings of a rolling bearing for the support of a vehicle wheel, including a first shield integral with the rotating ring of the rolling bearing carrying a magnetized ring with a pair of alternate poles, which is placed in front of, in operation, a passive sensor borne by a second shield attached to the fixed ring of the bearing; the sensor is inductive and has n polar pieces in a number proportional to the pairs of alternate poles of the magnetized ring; the configurations of shields and sensor are such that the elements measuring the relative speed are integral with the shields and protected outwards.
