ABSTRACT:
In an off-highway vehicle having an electric propulsion system which includes a motorized wheel, a traction motor and a transmission for transmitting power from the traction motor to the motorized wheel, wherein the transmission comprises a reduction stage, a low speed sun pinion defining a sun pinion cavity and a thrust washer, wherein the thrust washer includes a first surface portion movably associated with the low speed sun pinion via a thrust washer retainer and wherein the thrust washer is movably associated with the reduction stage via a lubrication plug is provided, wherein the lubrication plug includes a first plug portion having a radially extending portion movably associated with a second surface portion of the thrust washer and a second plug portion having a second plug portion structure which defines a plug cavity having a plug cavity inlet and at least one plug cavity outlet disposed adjacent at least a portion of the thrust washer, wherein the plug cavity inlet is disposed to communicate the sun pinion cavity with the plug cavity and wherein the at least one plug cavity outlet is disposed along at least one radial plane of the second plug portion to communicate the plug cavity with the thrust washer, such that a lubricant flowing through the sun pinion cavity and into the plug cavity inlet is allowed to flow out of the at least one plug cavity outlet such that the lubricant and the thrust washer lubricatingly interact.
