Patent ID: 10711660

Abstract:
An electric-hydraulic camshaft phaser assembly, including a hydraulic camshaft phaser and an electric camshaft phaser. The hydraulic camshaft phaser includes: a stator arranged to receive rotational torque and including a plurality of radially inwardly extending protrusions; a rotor arranged to be non-rotatably connected to a first camshaft and including a plurality of radially outwardly extending protrusions circumferentially interleaved with the plurality of radially inwardly extending protrusions; and a plurality of chambers bounded at least in part by the plurality of radially inwardly extending protrusions and the plurality of radially outwardly extending protrusions. The electric camshaft phaser includes: an input non-rotatably connected to the stator; an output gear; and at least one protrusion fixed to the output gear and arranged to be inserted into at least one slot of a second camshaft. The at least one protrusion is arranged to transmit rotational torque from the output gear to the second camshaft.
