Abstract
A wheelend assembly seal between the hub of a wheelend and a spindle shaft is provided. The wheelend assembly seal is a seal device having at least a static seal structure, a wear ring, and a dynamic seal structure. The dynamic seal structure comprises a resilient member that is biased such that in an uninstalled state, the resilient member diverges from an axially extending portion of the dynamic seal structure. When installed, the resilient member is compressed to be approximately parallel the axially extending portion and forms a seal between the surface of the resilient member and the outer surface of the spindle shaft.
