Abstract
Systems and method for a cam phaser are provided. In some configurations, the cam phaser includes a drive member having a first mating surface, a driven member having a second mating surface, and a locking mechanism arranged between the first mating surface and the second mating surface. The locking mechanism is operable to contact the first mating surface and the second mating surface, in response to an outside force applied to the driven member that loads the locking mechanism. The cam phaser further includes an engaging member. The engaging member is configured to selectively actuate the locking mechanism to enable rotation of the driven member relative to the drive member. The cam phaser may include a reaction mechanism configured to receive additional force from an input mechanism and selectively transmit the additional force to the driven member to unload the locking mechanism.
