Abstract: A system is provided for shielding a tone ring assembly in automotive vehicles. The system comprises a ring cap with a central aperture, a plurality of molding slides circularly arranged on a first side of the ring cap, a plurality of snap-fit arms and a plurality of pilot tabs positioned on a second side of the ring cap, where the plurality of pilot tabs and the plurality of snap-fit arms are arranged in concentric circles with the snap-fit arms forming an outer circle and the pilot tabs forming an inner circle, and where each pilot tab of the plurality of pilot tabs is positioned directly behind a corresponding snap-fit arm of the plurality of snap-fit arms. In one example, the system prevents metal to metal contact between a tone ring and a shaft during axle shaft installation.

Abstract: A tone wheel assembly includes a tone wheel. A first member is attached to the tone wheel. A second member is at least partially disposed around a portion of the first member. The second member includes a collar portion, one or more first leg portions extending axially from the collar portion, and one or more second leg portions extending axially from the collar portion. The one or more first leg portions include a first leg portion protuberance that extends radially from an outer surface of the one or more first leg portions. The one or more second leg portions include a second leg portion protuberance that extends radially from an outer surface of the one or more second leg portions.

Abstract: A breather assembly (100) for a vehicular drive axle (10). The breather assembly includes a body member (102) having a vertically extending drainback tube portion (114) and a horizontally extending connecting portion (120), and a curved formed hose member (104) to minimize leakage of lubricant (S) from the drive axle axle housing (26) and ingestion of exterior water into the housing.

Abstract: A lubrication system for the helical gear thrust washer, helical gear journal and inter-axle differential in tandem drive axles. The leading drive axle input shaft is journalled in a bearing supplied on one side with a gravity flow of lubricant from a passage receiving lubricant slinging from the power divider periphery, which receives lubricant slinging from the axle ring gear. The opposite side of the bearing has an annular lubricant chamber therearound formed by an annular baffle member surrounding the input shaft on the interior side of the bearing. The bearing is operative to pump lubricant to the annular chamber. An axial passage formed through a portion of the input shaft communicates the annular chamber with the differential gears. In one form the annular baffle member rotates with the input shaft and in the other form it is stationary.
