RADBEFESTIGUNG MIT AUF DER ACHSE MONTIERTEM AUFNEHMER

摘要

A wheel mounting includes an axle provided with a spindle, a hub located around the spindle, and an antifriction bearing located between the spindle and the hub for enabling the hub to rotate on the spindle with minimal friction. The axle also has a cylindrical ring seat located beyond its spindle and a shoulder located between the spindle and the ring seat. The ring seat has a stop located along it. The bearing has a cone located around the spindle, with its back face being against the shoulder, a cup located in the hub, and tapered rollers located between tapered raceways on the cone and cup. Beyond the large end of its raceway the cup is fitted with an excitor ring having a radial wall at the inboard end of the bearing. The ring seat carries a mounting ring having an axial wall provided with a formation that bears against the stop on the seat and an end edge that is against the back face of the inboard cone. Indeed, the axial wall is compressed between the back face of the inboard cone and the stop, so that the formation on the axial wall bears tightly against the stop on the ring seat. This fixes the mounting ring firmly in position axially with respect to the radial wall on the excitor ring. The mounting ring carries a sensor which is presented toward the radial wall of the excitor ring. The sensor produces a pulsating signal when the excitor ring rotates, and the frequency of that signal reflects the angular velocity of the hub.
