Instrumented anti-friction bearing for a wheel has the wheel coding and detection elements arranged facing each other at a radius which is less than that of the annulus containing the wheel mounting holes

摘要

#CMT# #/CMT# Antifriction bearing for guiding wheel rotation comprises a turning element (1) to which the wheel is connected and a fixed element (2) with an annular space between them filled by bearings. A rotation detection system has first means (3) mounted on the front surface of the turning element, the other part (4) of the detection system being mounted on the fixed element opposite to the first part. The detection means are placed in an annular space between moving and stationary elements with the radius of the fixed element exterior being slightly less than that comprising the mounting holes. #CMT#USE : #/CMT# Instrumented anti-friction bearing for a wheel. #CMT#ADVANTAGE : #/CMT# The sensor for detecting the coding signals is protected against all shocks and any projections. The resolution of the rotary position signal is as accurate as possible for the size of the positioning system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a partially sectioned view of an inventive bearing. 1 : turning element 2 : fixed element 3, 4 : first and second parts of the angular position detection system 5 : mounting hole.
