Abstract:
A wheel hub and bearing assembly mountable on a vehicle axle comprising:a) a wheel hub having a longitudinal axis;b) a pair of bearings within said wheel hub, said bearings in spaced axial relation along the longitudinal axis of said wheel hub;c) a lubricant cavity within said wheel hub between said axially spaced bearings;d) a vane disposed within said lubricant cavity and extending radially outwardly with respect to the longitudinal axis of said wheel hub, the vane having a cap portion and a base portion, the vane including:i) a first passage including,a transverse port in the cap portion for receiving lubricant into the vane upon rotation of said wheel hub on said axle,a radial passageway in the base portion for directing lubricant flow from said transverse port in a radially inward direction towards the longitudinal axis of said wheel hub, andan axial nozzle in the base portion for directing lubricant flow from said radial passageway in an axial direction, with respect to the longitudinal axis of said wheel hub, out of the vane and within said lubricant cavity towards one of said axially spaced bearings, andii) a second passage including,a transverse port in the cap portion for receiving lubricant into the vane upon opposite rotation of said wheel hub on said axle,a radial passageway in the base portion for directing lubricant flow from said transverse port of said second passage in a radially inward direction towards the longitudinal axis of said wheel hub, andan axial nozzle in the base portion for directing lubricant flow from said radial passageway of said second passage in an axial direction, with respect to the longitudinal axis of said wheel hub, out of said vane and within said lubricant cavity towards one of said axially spaced bearings.
