Abstract
Abstract An arrangement for mounting an angular velocity detector on a vehicle wheel hub and axle assembly includes an axially directed cylindrical flange on the wheel hub which cooperates with a radially inner surface of the tone wheel which is also provided with a radially inwardly directed flange abutting the end of the flange on the wheel hub. The teeth of the tone wheel are mounted on the radially outer surface of the tone wheel and the tone wheel may be hot-keyed onto the flange on the wheel hub. The magnetic pickup is mounted on one of a pair of arcuate clamping members which surround the axle and which are secured together by means of a pair of bolts. A protective apertured cover is mounted on the magnetic pickup intermediate the pickup and the tone wheel to protect the pickup during positioning of the two elements during assembly.
