Abstract:
A seal assembly that includes a case member, which is configured to be received in a seal bore in a housing, a first dynamic seal, which is configured to sealingly engage a shaft that is rotatably supported in a housing, and a second dynamic seal that is configured to sealingly engage a slinger that is coupled to the shaft for rotation therewith. The second dynamic seal has an annular seal lip and a spring member that is located on an “air side” of the annular lip seal. The spring member is configured to bias the annular lip seal in a pivoting manner about the axis and into contact with a surface on the slinger.

Claim (Index 1):
A seal assembly comprising:\n a case structure defining an annular case member that is disposed longitudinally along an axis; a first dynamic seal coupled to the case structure and extending therefrom in a first axial direction along the axis, the first dynamic seal having a first annular seal lip and a first spring member, the first annular seal lip having a first sealing surface that is disposed about the axis concentric with the annular case member such that the first sealing surface is spaced from the axis by a first distance (r 1 ), the first spring member engaging the first annular seal lip and biasing the first sealing surface in a radially inward direction toward the axis; and a second dynamic seal coupled to the case structure and extending therefrom in a second axial direction along the axis, the second axial direction being opposite the first axial direction, the second dynamic seal having a second annular seal lip and a second spring member, the second annular seal lip being frustoconical in shape and diverging from the axis with increasing from the case structure in the second axial direction, the second annular seal lip having a second sealing surface that is disposed concentrically about the axis such that the second sealing surface is spaced from the axis by a second distance (r 2 ) that is larger than the first distance (r 1 ), the second spring member engaging the second annular seal lip and biasing the second sealing surface toward the axis, the second spring member being a type of annular leaf spring haying a frustoconical portion that is matingly engaged with the second annular seal lip.
