WHEEL SUPPORT BEARING WITH ROTARY SENSOR

摘要

PURPOSE: To enable the formation of a rotary sensor at a low cost and improve the mechanical strength and sealability of a connection part of the rotary sensor and a harness in a wheel support bearing containing the rotary sensor. CONSTITUTION: A rotary sensor 8 fixed on an inner race 3 is made up of a stator 12 press molded and a coil 13 wound on the inside of the stator 12 and a circular plate 14 is linked to the rear of the stator 12. A lead 18 led from the coil and the harness 23 are connected within a resin molded part 22 fixed on the circular plate 14. The lead 18 is surrounded by a resin sleeve 24 and seal rings 25 and 27 and the connected part of the lead and harness are reinforced and sealed.
