Abstract: A hydraulic-expansion chuck for clamping a workpiece includes an annular body, an inner circumferential surface, an outer circumferential surface, and an axis of rotation. The chuck also includes a channel integrated into the annular body for receiving a pressurized hydraulic fluid to clamp the workpiece. The channel has an annular peripheral channel section formed radially between the inner circumferential surface and the outer circumferential surface. The chuck also includes a holding contour with a plurality of expansion lugs disposed on the inner circumferential surface and a plurality of further channel sections branching off from the channel. At least one of the plurality of further channel sections extends into a respective lug of the plurality of expansion lugs, and the hydraulic-expansion chuck is manufactured by an additive manufacturing process.

Abstract: A hydrodynamic thrust bearing for a torque converter comprising: an axis of rotation; a first radial thrust surface; a second radial surface, opposite the first radial thrust surface, including at least two axially protruding anti-rotation pins for preventing relative motion with one of either a stator assembly or an impeller once assembled; an inner circumferential surface defining an opening concentric with the axis of rotation; an outer circumferential surface; and, an axial retention means for attaching to the one of either a stator assembly or an impeller and including at least two resilient tabs, each tab comprising: a deflectable portion; a lockable portion; and, an axial portion having a first width and connecting the deflectable portion and the lockable portion. A torque converter having a hydrodynamic thrust bearing as described is also provided.

Abstract: A method of forming a target wheel for a camshaft phaser assembly is disclosed. The method includes providing a sheet metal body, and stamping the sheet metal body to form a sensor tab. The sensor tab includes a medial flange positioned between first and second axially extending edges. The sensor tab includes: at least one inner corner defined between the medial flange and at least one of the first axially extending edge or the second axially extending edge, and at least one outer corner defined between the medial flange and at least one of the first axially extending edge or the second axially extending edge. The method includes forming a groove in the at least one inner corner.

Abstract: A differential assembly includes a side gear configured to receive torque and a wedge clutch. The wedge clutch includes a hub configured to connect with a shaft and a wedge element radially disposed between the hub and the side gear. The wedge element has an inner surface seated on the hub and an outer surface engageable with the side gear. The wedge element is radially expandable and has a rested state in which the side gear and the hub are rotatable relative to each other and an expanded state in which the side gear and hub are rotationally locked to each other.

Abstract: A torque coupler includes an input side and an output side, which are situated rotatably around an axis of rotation, and in addition an intermediate plate for coupling with the input side, an output flange for coupling with the output side, a spring damper for coupling the intermediate plate with the output flange, and a centrifugal force pendulum having a pendulum flange and a pendulum mass. Here the pendulum flange extends between a first area, in which the pendulum flange is attached to the intermediate plate, and a second area, in which the pendulum mass is attached to the pendulum flange. The output flange has a cutout, through which a section of the pendulum flange which connects the two areas runs.

Abstract: An electromagnetic actuating unit of a hydraulic directional valve, which has an armature and a first and a second magnet yoke. The first and the second magnet yokes at least partially bind an armature space, the armature is arranged in the armature space so as to be axially displaceable, and the first and the second magnet yokes face each other in the axial direction of the armature.
