Abstract: A wheel end assembly includes a seal for sealing the annular space between an inner member and an outer member, one of which is a static component and the other a rotatable component. The seal includes an annular case having a cylindrical portion engaged with the static component and an annular flange portion extending radially from the cylindrical portion so as to be oriented vertically with respect to the horizontal central axis. An annular seal member is attached to the flange portion of the case and has at least one sealing lip engaged with the rotatable component so as to separate the annular space into a first chamber and a second chamber. Further, at least one air vent hole extends axially through the flange portion of the case so as to fluidly connect the first chamber with the second chamber.

Abstract: An oil seal having the usual lips for retaining oil and a guide member made of a variety of relatively stiff or rigid materials. The guide member is made slightly larger than the smallest diameter of the seal member when the seal rests on the shaft. The seal member can have the guide member on either the air side or the oil side of the seal. The disclosure also relates to a shipping plug, which is inserted into the seal and retains the oil in place during shipping when the seal is installed but a shaft is not installed.

Abstract: A controllable magnetorheological fluid valve for controlling magnetorheological fluid. The controllable fluid valve includes a magnetorheological fluid conduit with a magnetorheological fluid path. The controllable fluid valve includes a north magnetic pole and a south magnetic pole, with the south magnetic pole proximate the north magnetic pole with a magnetic discontinuity spacer between the south magnetic pole and the north magnetic pole wherein the spacer forces nontraversing magnetic flux lines from said north pole out into the magnetorheological fluid path and then back into the south pole.

Abstract: A tone ring assembly for use on a rotatable machine part. The tone ring is able to generate a varying voltage output when rotated at varying speeds. A fixed position magnetic sensor detects this voltage. The tone ring comprises an axially extending main body portion having a plurality of areas able to generate a voltage upon rotation. A retainer having at least one radial flange prevents axial movement of the tone ring and the tone ring includes ribs and spaces on its inside diameter to permit oil to pass therethrough.

Abstract: An accumulator piston for an automatic transmission. The piston comprises two components, the first and second being cup elements welded together with their closed ends in abutting relation. The lower cup includes a curled back portion with a radial flange having an axially extending bi-directional oil seal thereon, and spaced apart recesses in the curled back portion to permit oil to flow therein. The upper cup includes a radial flange of reduced diameter compared to the lower cup flange. The flange also has a lip seal thereon. The piston is spring-loaded and moves up and down in a bore and counterbore in response to fluid flow on either side of the piston to absorb shifting shocks.
