An integration kit is disclosed herein that allows for mounting of a resolver trigger wheel relative to a bearing assembly, resolver, and rotor. The integration kit simplifies assembly and saves space. The integration kit includes a resolver integration sleeve that includes a first axial section including a radially inner surface defining a bearing support and radially inwardly extending flange defining an axial abutment surface. The resolver integration sleeve also includes a second axial section including at least one anti-rotation slot dimensioned to receive a portion of a trigger wheel, at least one anti-rotation tab extending axially towards the first axial section and dimensioned to be received by a rotor, at least one securing tab extending radially outward and configured to engage a trigger wheel, and a radially outwardly extending flange.

A hydrodynamic bearing includes an annular washer having an annular face configured to form a hydrodynamic thrust bearing. The annular face defines a plurality of circumferentially spaced oil grooves having opposing first and second lips extending between inner and outer diameters of the face. The annular face further defines a plurality of circumferentially spaced thrust segments alternating with the grooves such that each of the thrust segments is disposed between an associated pair of first and second ones of the grooves. Each of the thrust segments includes a land that is raised on the face relative to the first and second lips of the associated pair, a first ramp extending from the second lip of the first groove to a first side of the land, and a second ramp extending from the first lip of the second groove to a second side of the land.

Hydrodynamic bearing

A wedge clutch includes first and second races supported for rotation about a common axis. The first race defines a cam surface and circumferentially arranged pockets recessed into the cam surface. A wedge element is formed of circumferentially arranged wedges each having an ear disposed in one of the pockets. Resilient members are disposed in the pockets and act between the ears to bias the wedge element to a contracted position in which the wedge elements collectively contract towards the axis and the clutch is engaged. A cage is axial movable towards the wedge element to engage with the ears to compress the resilient members and move the wedge element to an expanded position in which the wedge elements collectively expand away from the axis and the clutch is disengaged.

Wedge clutch with slotted carrier

A wedge clutch, including: a hub; a carrier; a first wedge plate segment radially located between the hub and the carrier and including a first ramp sloping radially inwardly in a first circumferential direction and including a first circumferential end; a second wedge plate segment radially located between the hub and the carrier and including a second ramp sloping radially inwardly in a second circumferential direction, opposite the first circumferential direction and including a second circumferential end. In a free-wheel mode of the wedge clutch, one of the hub or the carrier is rotatable with respect to the other of the hub or the carrier. In a locked mode of the wedge clutch: the hub and the carrier are non-rotatably connected for rotation of the hub in the first circumferential direction; and the first and second circumferential ends are in contact.

Bi-directional wedge clutch with lockup prevention

An actuator assembly is disclosed. The actuator assembly includes a driven component, a coil housing including a first coil and a second coil, and an armature housing including a first armature and a second armature. The first armature is axially fixed to the armature housing, and the second armature is slidably received within the armature housing and axially fixed to the driven component. In a first energized state, the first coil is energized, and the driven component is driven a first predetermined distance towards the coil housing. In a second energized state, the first coil and the second coil are energized, and the driven component is driven a second predetermined distance towards the coil housing.

Multi-stage actuator assembly

A wedge clutch includes a first race rotatable about an axis and having first tapered surfaces annularly arranged about the axis, and a second race rotatable about the axis and concentric with the first race, the second race having a circumferential groove. A plurality of wedge segments are annularly arranged about the axis, each wedge segment having a second tapered surface contacting one of the first tapered surfaces. A plurality of pawls extend radially through at least a portion of either the first race or the second race. Each pawl is circumferentially aligned with a respective gap between two adjacent wedge segments. An actuating ring is configured to move axially along the axis. Axial movement of the actuating ring engages the pawls to force each pawl radially into the respective gap to separate the two adjacent wedge segments.

Radial actuation of disengagement for wedge clutch

A switchable wedge clutch includes an inner race, and an outer race that has an inner surface defining a plurality of tapered regions. A plurality of wedge plate are disposed between the inner and outer races, and are moveable circumferentially about the inner race. Each wedge plate segment has a tapered outer surface configured to engage and slide relative to the tapered regions of the outer race. An actuating ring has a plurality of axially-extending tapered fingers configured to fit between two of the wedge plate segments. The wedge plate segments are wedged between the tapered regions and the inner race to lock the inner and outer race together. Axial movement of the actuating ring forces the wedge plate segments circumferentially against biasing forces of springs to unwedge the wedge plate segments from between the outer race and the inner race and unlock the wedge clutch.

Switchable cylindrical wedge clutch

A wedge plate clutch, including: an axis of rotation; a hub; an outer ring located radially outwardly of the hub; a plurality of circumferentially aligned wedge plate segments radially disposed between the hub and the outer ring; a cage; and a dual function spring including a first plurality of resilient elements urging the cage in a first axial direction and a second plurality of resilient elements urging the plurality of circumferentially aligned wedge plate segments radially inwardly. For a disconnect mode for the wedge plate clutch, the hub and the outer ring are rotatable with respect to each other. To transition from the disconnect mode to a connect mode for the wedge plate clutch, in which the hub and the outer ring are non-rotatably connected, the cage is arranged to displace the first plurality of circumferentially aligned wedge plate segments.

Wedge plate clutch with dual function spring

A clutch includes a carrier defining an annular groove and a hub coaxial with the carrier and defining an outer surface. The hub is axially movable relative to the carrier between at least a first position and a second position. A wedge disk has a first edge disposed on the outer surface, a second edge disposed in the annular groove, and a face extending between the edges and defining an annular shoulder. The disk engages between the carrier and the hub when the hub is in the first position to lock the clutch, and the carrier and the hub are rotatable relative to each other when the hub is in the second position. An annular retainer is configured to prevent radial expansion of the disk when the hub is in the second position and to permit radial expansion of the disk when the hub is in the first position.

Wedge clutch with anti-expansion retainer

A planetary pin used for staking in a planetary gear system is provided. The planetary pin comprises a cylindrical body, a first end having a first end surface, a second end having a second end surface, and a circular groove formed in at least one of the end surfaces concentric with the cylindrical body.

Staked planet pin

A planet pin for use in a planetary gear system and a gear system including a planet pin are disclosed. The inventive planet pin provides a plurality of radial passages in fluid communication with an axial passage which can advantageously eliminate, or substantially reduce, the need to orient a planet pin in a planetary gear system.
