ABSTRACT:
A speed sensing differential axle mechanism provides a plurality of teeth formed in a small diameter end portion of a differential case. In a preferred form, the teeth are integral to the case, spaced uniformly about the small diameter end portion thereof, and are disposed for relative rotation with respect to a stationary electronic pickup element secured rigidly in an associated external carrier. In the preferred embodiment, the pickup element is totally enclosed within the carrier, whereby it is protected from external environments, as well as from splash and spray oil circulating within the differential assembly. For the latter purpose, an internal baffle is utilized to protect the internal pickup element from the oil.
