Abstract: An apparatus (10) and method for controlling an angular position of a camshaft (12) in an internal combustion engine having a camshaft phaser (14) for controllably varying the phase relationship between a crankshaft of the internal combustion engine and the camshaft (12). The camshaft phaser (14) can be actuated by an electric motor (16) having an actuator shaft (18) operating through a gear reduction drive train (20) having a stationary adjusting member (22) which rotates when a phase change adjustment is desired. A sensor (30) can generate a signal corresponding to an angular position of the stationary adjusting member (22) of the gear reduction drive train (20). An engine control unit (40) can adjust a position of the camshaft (12) through operation of the electric motor (16) for rotating the stationary adjusting member (22) based on the generated signal corresponding to the angular position of the stationary adjusting member (22).

Abstract: An electric variable valve timing apparatus includes a sprocket unit and an electric motor. The electric motor is fixed to a chain cover with bolts. The chain cover includes plural bosses each having an internal thread to which one of the bolts is threaded. The bosses extend from the chain cover toward the sprocket unit to positions at which the bosses face an outer periphery of the sprocket unit in a radial direction. The bosses are arranged such that, when the sprocket unit moves downward from an attaching position, at which the sprocket unit is attached to the camshaft, at least two bosses are engaged with the sprocket unit to restrict downward movement of the sprocket unit, and that the sprocket unit is allowed to move between a location outside of a space covered by the chain cover and the attaching position.

Abstract: A variable valve device for an internal combustion engine for varying operating characteristics of engine valves by changing a relative rotational phase of a camshaft to a timing sprocket has an electric motor that rotates the camshaft relatively to the timing sprocket, a cover member provided to cover a front end section of the electric motor, and an angle sensor that detects a rotational angle position of a motor output shaft. The angle sensor includes a detected unit provided inside of a top end section of the motor output shaft and a detecting unit provided on the cover member so as to be opposed to the detected unit through a minute clearance. A metal disk-shaped reinforcing plate is molded and fixed inside of a cover main body of the cover member mainly formed of a synthetic resin material, thus enhancing the entire rigidity of the cover main body.

Abstract: A valve timing controller includes a driving rotor, a driven rotor, a planetary rotor, a planetary carrier, and an elastic component to produce a restoring force biasing the planetary rotor to an eccentric side such that the driving rotor is inclined to the driven rotor. The driving rotor has an inclination angle θ1 relative to the driven rotor in a first inclination state where the driving rotor is in contact with the driven rotor on both sides in the axial direction. The inclination angle θ1 is smaller than an inclination angle θ2 in a second inclination state where the driving rotor is in contact with the driven rotor on both sides in the radial direction, and is smaller than an inclination angle θ3 in a third inclination state where the driving rotor is in contact with the camshaft on both sides in the radial direction.

Abstract: In a definition cross-section of a planet gear located on an eccentric side in a radial direction relative to a driving rotor and a driven rotor, an imaginary straight line is defined by connecting a center of a planet side outer arc part that configures a raceway groove of a planet outer wheel on the eccentric side to a center of a solar side outer arc part that configures a raceway groove of a solar outer wheel on an opposite side opposite from the eccentric side. A planet side inner arc part of a planet inner wheel and a solar side inner arc part of a solar inner wheel are located on the imaginary straight line in the definition cross-section.
