Abstract:
A variable camshaft timing (VCT) assembly includes an independent VCT device that can couple with a first camshaft and change an angular position of the first camshaft relative to the angular position of a crankshaft. The independent VCT device has a stator and an output fixedly coupled with the first camshaft. The VCT assembly also includes a dependent VCT device that angularly adjusts a second camshaft in response to angular adjustment of the first camshaft. The dependent VCT device has a camshaft link coupled with the output of the independent VCT device; the camshaft link has a slot positioned radially outwardly from an axis of camshaft rotation. The independent VCT device also includes a planetary gear link having a geared surface configured to engage a geared surface coupled to the second camshaft, a planetary gear pin received by the slot of the camshaft link, and a planetary gear pivot; angular movement of the output relative to the stator moves the planetary gear pin relative to the slot and the planetary gear link about the pivot thereby transmitting angular motion of the first camshaft to the second camshaft through the planetary gear link.
