Abstract
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.
