The heat exchanger has a plurality of heat exchanger plates, each of which having a hub, a rim member, and disc spring portion that interconnects the hub and the rib member. Each disk spring portion defines a plurality of coolant apertures. The heat exchanger plates are press-fit to the rotor shaft such that each disc spring portion is deflected from a pre-installation state, and each rim member is engaged to an interior surface of the rotor shaft while being spaced apart from adjacent rim members along a rotational axis of the rotor. A first coolant passage is disposed through the hubs of the plates. The coolant apertures in the heat exchanger plates cooperate to form a plurality of second coolant passages.

Abstract: A vehicle driveline component with a ball-ramp mechanism that includes a first ball-ramp ring, a second ball-ramp ring and a plurality of balls. Each of the first and second ball-ramp rings have a plurality of ball supports that define ball tracks that receive the balls. Each of the ball supports has a first radial width at a first location and a second radial width at a second location. The first and second widths are different to minimize the amount of material that forms the first and second ball-ramp rings.

Abstract: An electric drive unit having a stator body, a plurality of sets of field windings mounted to the stator body, a rotor received in the stator body and rotatable relative to the stator body, a plurality of phase terminals, and a current sensor assembly. Each of the phase terminals is coupled to an associated one of the sets of field windings. The current sensor assembly has a plurality of current sensor laminations, and a sensor. The current sensor laminations are generally C-shaped and are abutted against one another to form a sensor lamination stack. The sensor lamination stack defines a gap. The current sensor laminations are disposed about a corresponding one of the phase terminals. The sensor is disposed in the gap.

Abstract: A method includes determining a vector state of an alternating current (AC) electrical machine. The method includes, when the vector state is a zero-vector state, obtaining a plurality of phase current samples of the AC electrical machine, determining a decay time constant based on the plurality of phase current samples, and determining a resistance of a winding of the AC electrical machine based on the decay time constant. The method further includes selectively activating a plurality of switches of an inverter configured to provide power to the AC electrical machine based at least on the resistance of the winding of the AC electrical machine.

Abstract: A piston assembly that includes a pair of piston members that are formed of compacted powdered metal. The piston members have sets of locking features that include alternating projections and recesses that are spaced circumferentially about and intersect a rod aperture that extends through the piston member. Each projection is formed along a projection axis, which extends radially from a center axis along which the rod aperture is formed, and has a pair of opposite side walls and an end wall that connects the side walls to one another on a side of the projection that is opposite the rod aperture. The recesses on each piston member are configured to matingly and frictionally receive the projections on the other piston member.
