Abstract
A camshaft assembly, including a camshaft phaser with: stator; rotor including first plurality of circumferentially aligned ramps; and second plurality of circumferentially aligned ramps offset from the first plurality of ramps in a first axial direction; first and second wedge plates radially disposed between the rotor and the stator; and camshaft non-rotatably connected to the rotor. In a drive mode: the stator is arranged to receive first torque and to rotate in a first direction; the assembly is arranged to operate in successive cycles of a first phase followed by a second phase; in the first phase the first wedge plate non-rotatably connects the stator and the rotor while the second wedge plate is rotatable with respect to the stator; and in the second phase, the second wedge plate non-rotatably connects the stator and the rotor while the first wedge plate is rotatable with respect to the stator.
