Abstract: A vehicle driveline component having a housing, first and second shafts supported by the housing for rotation about a rotary axis, a two-speed transmission in a power transmission path between the first and second shafts, a shift fork and a failsafe spring. The two-speed transmission has a movable member that is movable along the rotary axis between a high-speed position, in which the two-speed transmission operates in a first gear ratio, and a low-speed position in which the two-speed transmission operates in a second gear ratio that provides a higher speed reduction between the first and second shafts than the first gear ratio. The shift fork is coupled to the movable member for movement therewith along the rotary axis. The failsafe spring is disposed coaxially about the rotary axis and biases the movable member toward the high-speed position.

Abstract: A dual drive gear of an actuation assembly for a transfer case includes an annular disk, a dual drive gear hub, and a sense plate. The annular disk has an inner periphery and an outer periphery. The outer periphery defines a plurality of teeth projecting radially outward. The dual drive gear hub is attached to the inner periphery of the annular disk and has an inner surface that defines a bore extending through a center of the dual drive gear. The dual drive gear hub includes a pair of curved walls projecting from a first axial end face of the annular disk. The sense plate projects from a second axial end face of the annular disk opposite of the first axial end face and includes a plurality of curved wall sections. The annular disk, the dual drive gear hub, and the sense plate are formed together as a single piece.

Abstract: 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.

Abstract: 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.
