A vehicle driveline component having a housing, a shaft received in the housing, a lubricant pathway coupled to the shaft for rotation therewith, a sleeve disposed coaxially about the lubricant pathway, and a fluid feed conduit coupled to the component housing. The lubricant pathway is disposed helically about an exterior surface of the shaft. The sleeve has a feed port. The fluid feed conduit having an outlet that is in fluid communication with the feed port. Lubricant in the lubricant pathway that has been discharged from the outlet of the fluid feed conduit travels in a predetermined axial direction along the rotary axis of the shaft when the shaft rotates about the rotary axis in a predetermined rotational direction.

Vehicle driveline component having a lubricant pathway for transmitting a lubricating fluid to desired location

A driveline component that includes a shaft, a friction clutch, a lubricant passage and an oil distributor sleeve. The friction clutch includes a hub with a hub portion and a plate mount. The oil distributor sleeve is received on the plate mount so that a lubricant chamber is disposed radially between the oil distributor sleeve and the hub portion. The lubricant passage is disposed between the shaft and the lubricant chamber and has a passage outlet that intersects the lubricant chamber. The oil distribution sleeve receives lubrication discharged from the passage outlet and directs the received lubrication to apertures formed through the plate mount.

Driveline component having oil distributor sleeve

Vehicle driveline component having rotatable lubricant pathway for transmitting lubricating fluid to desired location

A transfer case having a lubrication guide with an inlet, an outlet and an elongated tubular portion that is disposed between the inlet and the outlet. The lubrication guide is coupled to a drive assembly that transmits rotary power between a pair of output shafts such that the inlet is disposed proximate a first rotary component of the drive assembly to receive splash lubrication (i.e., slung lubrication and/or surge lubrication) therefrom.

Transfer case having a lubrication guide

A power transmitting device that includes a shaft, a friction clutch, a lubricant passage and an oil spout. The friction clutch defines a lubricant chamber. The lubricant passage is disposed between the shaft and the lubricant chamber and has a passage outlet that intersects the lubricant chamber. The oil spout is received in the lubricant chamber and extends along a longitudinal axis of the shaft such that the oil spout is disposed about the lubricant passage and a portion of a hub portion of the friction clutch. The oil spout diverges radially outwardly from the hub portion with increasing distance from the lubricant passage in a direction toward an outlet of the oil spout.
