    摘要： Systems and method for a cam phaser are provided. In some configurations, the cam phaser (100) includes a drive member (105) having a first mating surface, a driven member (110) having a second mating surface, and a locking mechanism (115) 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 (120). 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.

    摘要： The systems and methods described herein provide an approach for cam phase angle control where an axial or rotational position of an actuator of a cam phaser has a direct relationship to the phase angle of the cam shaft, allowing for accurate cam phasing without the need for cam shaft or crank shaft position sensors. Providing phase angle adjustability without the need for crank shaft or cam shaft position sensors enables control of phase angle solely by sensing the axial or rotational position of the actuator of the cam phaser.

    摘要： A valve opening and closing timing control apparatus (1) includes: a driving side rotator (A) disposed rotatably about a rotation axis (X) and configured to rotate synchronously with a crankshaft (2) of an internal combustion engine (E); a driven side rotator (B) disposed rotatably about the rotation axis and configured to be rotatable relative to the driving side rotator and to rotate integrally with a valve opening and closing camshaft (3) of the internal combustion engine; and a phase adjustment mechanism (C) configured to set a relative rotation phase between the driving side rotator and the driven side rotator by a driving force of an electric actuator (M). The phase adjustment mechanism includes: an internally toothed ring gear (21); an inner gear (22); and a drive shaft (24), and the valve opening and closing timing control apparatus further includes: a biasing member (25); and a displacement regulation portion (T).
