Abstract
A vehicle driveline component includes a hollow motor shaft and a link shaft. The hollow motor shaft is supported for rotation about an axis including a plurality of grooves extending along an interior surface of the motor shaft. The link shaft cooperates with the interior surface of the motor shaft and the grooves to define a space between the link shaft and the motor shaft. The grooves are configured to force liquid lubricant to flow through the space in a longitudinal direction relative to the link shaft and the motor shaft when the motor shaft rotates. The link shaft includes a lubricant passage, a first connecting lubricant passage, and a second connecting lubricant passage. The lubricant passage extends along a longitudinal direction of the link shaft. The first and second connecting lubricant passages provide fluid communication between the longitudinal lubricant passage and the space.
