Patent ID: 10060303

Abstract:
A camshaft phaser comprising an advance one-way clutch and a retard one-way clutch. The camshaft phaser comprises an input component arranged to receive torque from an engine, an advance inner ring, a plurality of rollers circumferentially arranged around the advance inner ring, an advance outer ring radially disposed between the input component and the advance inner ring, and an actuation assembly arranged to be disposed within a camshaft, the actuation assembly comprises advance locking pin assemblies arranged in advance channels and an actuator rod. For an advanced mode, the actuator rod is arranged to radially displace advance locking pin assemblies to non-rotatably connect the camshaft and advance inner ring, the rollers ride up ramps on advance outer ring, which expands radially to engage the input component. The retard clutch is substantially similar, and arranged diametrically opposed, to the advance clutch.
