Device for gauging the revolving speed between two members in relative rotation.

摘要

A revolving speed gauge device is formed by a revolving phonic wheel (14) which is fixed to the inner revolving race (10) of a wheel bearing and a sensor (28) that faces the phonic wheel an is assembled in a C shaped flux concentrator (15). The latter is fixed to the suspension standard (16) of the vehicle by means of a ring (17) that is provided with an elastic horizontal tongue (32) adapted for quick coupling the flux concentrator (15) and the sensor (28) to the standard (16).
