A camshaft phaser arrangement configured for a concentric camshaft assembly having inner and outer camshafts is provided. The camshaft phaser arrangement includes a first camshaft phaser that is configured to be non-rotatably connected to both the inner and outer camshafts, and a second camshaft phaser that is configured to be non-rotatably connected to one of the inner or outer camshafts.

Camshaft phaser arrangement for a concentric camshaft assembly

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.

A camshaft phaser arrangement configured for a concentric camshaft having inner and outer camshafts is provided. The camshaft phaser arrangement includes a first camshaft phaser and a second camshaft phaser. Each of the camshaft phasers is configured to be connected to either the inner or the outer camshaft. One or more couplers are arranged to torsionally couple the first camshaft phaser to the second camshaft phaser. A first end of the coupler is received by a radial slot configured within either the first or second phaser.

A variable cam phaser system including a variable cam phaser and a vibration damper fixed to the variable cam phaser is disclosed. A method for damping vibration for a variable cam phaser is also disclosed. The method includes providing a variable cam phaser, providing a vibration damper, and fixing the vibration damper to the variable cam phaser.
