Abstract
Official abstract text for this publication.
A variable cam timing assembly ( 10 ) and method for an internal combustion engine of a motor vehicle includes a cam phaser ( 22 ) connected between an inner camshaft ( 12 a ) and an outer camshaft ( 12 b ) of a concentric camshaft ( 12 ). A torsional drive mechanism ( 14 ) connects between the cam phaser ( 22 ) and the inner camshaft ( 12 a ) for transmitting rotational torque. The torsional drive mechanism ( 14 ) permits adjustment for perpendicularity and axial misalignment of the inner and outer camshafts ( 12 a, 12 b ), while maintaining a torsionally stiff coupling between the cam phaser ( 22 ) and one of the inner and outer camshafts ( 12 a, 12 b ) of the concentric camshaft ( 12 ). The torsional drive mechanism ( 14 ) can be formed from one of a flexible shaft coupling ( 40 ), a transversely split driven gear ( 140 ), a transversely split sprocket ring gear ( 240 ), a transverse face spline gear ( 340 ), and a pin and slot combination drive ( 440 ).
First claim
Opening claim text (preview).
What is claimed is: 1. In a variable cam timing assembly ( 10 ) for an internal combustion engine of a motor vehicle having a cam phaser ( 22 ) connected between an inner camshaft ( 12 a ) and an outer camshaft ( 12 b ) of a concentric camshaft ( 12 ), the improvement comprising: a torsional drive mechanism ( 14 ) connected between the inner camshaft ( 12 a ) and the outer camshaft ( 12 b ) of the concentric camshaft ( 12 ) for transmitting rotational torque therebetween,…
