Bearing assembly with wheel revolution detector

摘要

A bearing assembly with a revolution detector for detecting the number of revolutions of a vehicle wheel. It includes a pulse ring made of a ferromagnetic material into a multipolar magnet and fixedly mounted on the outer periphery of the inner ring and a sensor mounted on the outer ring at a position opposite to the pulse ring. The pulse ring has a mounting portion fixed to the inner ring, an uprising portion extending radially and outwardly from one end of the mounting portion, and a flange portion extending from the outer end of the uprising portion in parallel with and opposite to the mounting portion. The flange portion has its outer surface magnetized into a multipolar magnet.
