    Abstract: A harmonic drive of an electromechanical camshaft adjusters includes a drive wheel designed as a ring gear; an internally toothed output element mounted with radial play in the drive wheel; a further internally toothed element fastened to the drive wheel, the internal toothing of which has a diameter corresponding to the internal toothing of the output element; an adjuster assembly which is formed from a wave generator; an externally toothed flexible gear element which can be deformed by said wave generator, the external toothing of this flexible gear element meshing both with the internal toothing of the output element and with the internal toothing of the further element; an annular gap being formed between the further internally toothed element and an inner peripheral surface of a recess of the drive wheel. The width of the annular gap is at least partially greater than a radial play of the output element.

    Abstract: An object of the present invention is to obtain a controller device for a variable valve timing apparatus capable of controlling a phase to an arbitrary fixed valve timing from immediately before an internal combustion engine stops until after the internal combustion engine has stopped. The controller device for the variable valve timing apparatus according to the present invention performs, during engine stop processing of the internal combustion engine, normal control of changing the relative rotational phase of a camshaft to a most advanced position or a most retarded position when the rotational speed of a crankshaft is equal to or more than a first threshold, and low-speed control of fixing a current or a voltage supplied to the motor to be constant to maintain the relative rotational phase of the camshaft at the most advanced position or the most retarded position in a period from when the rotational speed of the crankshaft is lower than the first threshold until the rotational speed becomes zero.

    Abstract: A valve timing adjustment device includes: a driving rotating body that rotates with a crankshaft; a driven rotating body that rotates with a camshaft; a reduction mechanism configured to change a relative rotation phase of the driving rotating body and the driven rotating body by a driving force of an actuator; and a filter unit capable of capturing a foreign matter contained in lubricating fluid supplied into the reduction mechanism. The reduction mechanism includes: an internal gear portion having internal teeth formed inward in a radial direction, and an external gear portion having external teeth formed outward in the radial direction to mesh with the internal teeth. The driven rotating body has a supply hole penetrating in an axial direction. The filter unit has holes penetrating in the axial direction, and the holes are arranged in a flow path of the lubricating fluid connected to the supply hole.

    Abstract: The disclosure relates to a control device, in particular in an electromechanical camshaft adjuster, comprising an electric motor and a control transmission coupled to the electric motor via a coupling element and designed as a harmonic drive. A two-armed wire coupler is provided as the coupling element, the arms of which engage in openings of an inner ring of a waveform generator of the control transmission, and the wire coupler has a winding which is wound around the motor shaft of the electric motor in a non-rotating manner.

    Abstract: An electrically-actuated variable camshaft timing (VCT) phaser assembly, comprises a sun gear configured to receive input from an electric motor and one or more planet gears having radially-outwardly-extending gear teeth that engage the sun gear; a first ring gear, having radially-inwardly extending gear teeth that engage the radially-outwardly-extending gear teeth of the sun gear, configured to receive rotational output provided by a crankshaft; a second ring gear, having radially-inwardly extending gear teeth that engage the radially-outwardly-extending gear teeth of the sun gear, configured to couple to a camshaft; one or more planet gear pins that carry the planet gear(s) and engage a planetary gear set to prevent the relative rotation of the planet gear pin(s) relative to the planetary gear set; and one or more springs that bias the planet gear pin(s) and the planetary gear(s) toward the first ring gear and the second ring gear.
