A fluid flow system for a rotatable shaft assembly includes a first fluid flow device installed in a rotatable shaft, and a second fluid flow device installed in the rotatable shaft, spaced axially apart from the first fluid flow device. The first fluid flow device includes a wall portion having a radial dimension that retains oil in the rotatable shaft. The second fluid flow device includes a wall portion having a radial dimension that facilitates discharge of oil from the radial shaft. The first and second fluid flow devices each include a plurality of baffles on the respective wall portions thereof. The plurality of baffles drive the flow of fluid in an axial direction, from the first fluid flow device toward the second fluid flow device, as the first and second fluid flow devices rotate together with the rotatable shaft.

Lubrication and cooling system for rotatable components

One or more variable stiffness devices may be positioned between the splined coupling of a pair of rotating mechanical components to reduce or substantially eliminate backlash during operation. The variable stiffness device may include a spring pin that exerts a variable biasing force on mating surfaces of the pair of rotating mechanical components to maintain a relative position of the components in response to rotational and/or torsional forces exerted during operation.

Variable stiffness device to absorb backlash in splined components

An axle decoupler system comprises: an axle decoupler configured to selectively couple an axle of a vehicle with a wheel hub of the vehicle, the axle decoupler comprising: a sliding ring having first splines coupled to second splines on the axle, the sliding ring having a first position where the first splines are not also coupled to third splines on the wheel hub, and a second position where the first splines are also coupled to the third splines; and an electric motor for moving the sliding ring into the first or second position; and a one-way clutch coupling the axle and the wheel hub to each other.
