Abstract
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, a second camshaft phaser, and a coupling that non-rotatably connects the first camshaft phaser to the concentric camshaft assembly. Each of the camshaft phasers is configured to be connected to either the inner or the outer camshaft. The coupling accommodates for radial and axial offset between the first camshaft phaser and the second camshaft phaser.
Claims20
A camshaft phaser arrangement configured for a concentric camshaft assembly having inner and outer camshafts, the camshaft phaser arrangement comprising:
- a first camshaft phaser configured to be connected to one of the inner or outer camshafts, the first camshaft phaser having a center hub;
- a second camshaft phaser configured to be connected to a remaining one of the inner or outer camshafts via a cam fastener, the second camshaft phaser axially adjacent to the first camshaft phaser;
- a coupling disposed at least partially within the cam fastener, the coupling having a first end non-rotatably connected to a coupling end of the center hub and a second end configured to be non-rotatably connected to the one of the inner or outer camshafts;
- and,
- at least one first fastener connecting the first camshaft phaser to the second camshaft phaser;
- and,
- the coupling configured to accommodate at least one of a radial offset or an axial offset between the first camshaft phaser and the concentric camshaft assembly.
A camshaft phaser arrangement configured for a concentric camshaft assembly having inner and outer camshafts, the camshaft phaser arrangement comprising:
- a first hydraulic camshaft phaser configured to be connected to the inner camshaft, the first camshaft phaser having a center hub;
- a second hydraulic camshaft phaser configured to be connected to the outer camshaft via a cam fastener;
- a coupling having a first end non-rotatably connected to the center hub and a second end configured to be non-rotatably connected to the inner camshaft, the second end disposed within a through-aperture of the cam fastener;
- and,
- at least one fastener connecting a first stator of the first camshaft phaser to a second stator of the second camshaft phaser;
- and,
- the coupling configured to accommodate at least one of a radial offset or an axial offset between a first rotor of the first camshaft phaser and the inner camshaft.
A camshaft phaser arrangement configured for a concentric camshaft assembly having inner and outer camshafts, the camshaft phaser arrangement comprising:

- a second camshaft phaser configured to be connected to a remaining one of the inner or outer camshafts via a cam fastener, the second camshaft phaser axially adjacent to the first camshaft phaser;
- a coupling having a first end non-rotatably connected to a coupling end of the center hub and a second end configured to be non-rotatably connected to the one of the inner or outer camshafts;
- and,
- at least one first fastener connecting the first camshaft phaser to the second camshaft phaser;
- and,
- the coupling configured to accommodate at least one of a radial offset or an axial offset between the first and second camshaft phasers;
- and,
- the center hub extending within a through-aperture of the cam fastener.
