Adherence parameters measuring method for motor vehicle industry, involves obtaining intermediate signal by balanced sum of elementary signals from sensors, where efforts transmitted at level of wheel bearing is calculated from signal

摘要

The method involves delivering an elementary signal representing local deformation of rolling bearing caused by efforts transmitted between outer and inner rings (2, 3) via balls (4), by sensors (11-13) equipped with a wheel bearing, where the signal has a continuous component and a periodic disturbance due to the passage of balls at the right of sensors. An intermediate signal representing an average value of elementary signals, is obtained by balanced sum of elementary signals, where efforts transmitted at the level of wheel bearing is calculated from the intermediate signal.
