Bearing and drive assembly with combined wheel speed sensor

摘要

A powered wheel bearing has a solid spindle supported within a stationary hub by two rows of bearing balls. The innermost ball row has a separable race that is fixed in place by an abutting keeper ring that sits in an adjacent groove. The keeper ring, in turn, is prevented from dislodging by an overlaying shoulder on the sleeve of a CV joint that fits over the end of the spindle with interengaging splines. The joint sleeve is fixed to the spindle by an internal snap ring, so the motion of inserting the sleeve over the spindle is all that is necessary, both for attachment and alignment. The outside of the sleeve also carries regular teeth that provide the encoder ring for a speed sensor.
