Claim 0:
1. A camshaft assembly for a vehicle valvetrain having first and second engine valves, the camshaft assembly comprising:
a camshaft;
a first camshaft cartridge axially displaceable along the camshaft and including a plurality of first cam lobes configured to selectively impart movement to the first engine valve;
a second camshaft cartridge axially displaceable along the camshaft and including a plurality of second cam lobes configured to selectively impart movement to the second engine valve;
a single actuator configured to axially displace the first camshaft cartridge along the camshaft; and
a coupling between the first camshaft cartridge and the second camshaft cartridge, wherein axial displacement of the first camshaft cartridge selectively imparts movement to the second camshaft cartridge via the coupling for axial displacement of the second camshaft cartridge such that only the single actuator is needed to axially shift the first and second camshaft cartridges without having to directly engage the second camshaft cartridge,
wherein the first camshaft cartridge is axially displaceable relative to the second camshaft cartridge.
