Abstract: A sealing structure has a permanent magnet and a magnetic-flux guiding member for guiding magnetic flux of the permanent magnet to a brake shaft of a brake rotating member. The magnetic-flux guiding member surrounds an outer periphery of the brake shaft so as to form a sealing gap around the brake shaft. The sealing gap is communicated to a fluid chamber, in which magnetic viscous fluid is filled. A fluid sealing member is provided at the brake shaft at a housing outer side of the magnetic-flux guiding member to form an intermediate fluid chamber, in which an intermediate fluid made of non-magnetic liquid is filled.

Abstract: An engine is provided with a variable valve timing device which transmits a rotational force generated by a motor via a motor drive circuit to a cam shaft so as to change a rotational phase of the cam shaft relative to a crank shaft. An ECU cools a motor and a motor drive circuit when the change of the rotational phase stops during the changing of the rotational phase of the cam shaft to a target value is detected. In addition, the lock state is eliminated by driving the motor by the motor drive circuit after cooling the motor device.

Abstract: In a valve timing control apparatus configured to execute phase-control via a phase converter, a controller is configured to control a phase angle of a camshaft relative to a crankshaft during an engine stopping period to a target phase angle differing from a required phase angle suited for an engine operating condition. The controller is further configured to change the phase angle of the camshaft toward the required phase angle during a time period from a point of time when cranking starts to a point of time when detection of a rotational position of the camshaft initiates during an engine restarting period. The controller is still further configured to start feedback-control for the phase angle of the camshaft from the point of time of initiation of detection of the rotational position of the camshaft for bringing the phase angle of the camshaft closer to the required phase angle.

Abstract: The invention provides a planetary gear mechanism achieving a greater reduction gear ratio without increasing the number of teeth of the gears, thereby enabling downsizing. In a planetary gear mechanism 1, a sun gear 91 functioning as an input gear receives smaller load than an internally toothed output gear 45, so gears (second planet gears 95) having a smaller module are connected to the planet gears 93, and the sun gear 91 is in engagement with the second planet gears 95. The sun gear 91 is formed of a same module as the second planet gears 95. The rotation of the sun gear 91 is reduced in speed and transmitted to the second planet gears 95, and rotation of the second planet gears 95 rotated at a reduced speed is further reduced by the slight difference in the numbers of teeth of the ring gear 44 and the internally toothed output gear 45 before being output.

Abstract: A method for determining a wear value of a transmission element between a crankshaft and a camshaft of a reciprocating piston internal combustion engine, in particular a timing chain or toothed belt, is provided. The camshaft is driven by the transmission element via a drive part, for example a camshaft gearwheel. In each case, at least one measurement value for the phase position of the drive part relative to the crankshaft is determined at time intervals during which the crankshaft drives the camshaft, and the wear value is determined from the difference between the measurement values.

Abstract: A control device for a variable valve timing apparatus that changes valve timing of at least one of an intake valve and an exhaust valve of an internal combustion engine includes an actual valve timing computing unit and a valve timing controlling unit. The actual valve timing computing unit computes actual valve timing. The valve timing controlling unit controls the variable valve timing apparatus to maintain present valve timing during starting of the internal combustion engine before the actual valve timing computing unit becomes capable of computing the actual valve timing. The valve timing controlling unit controls the variable valve timing apparatus such that the actual valve timing becomes target valve timing during the starting of the internal combustion engine after the actual valve timing computing unit becomes capable of computing the actual valve timing.
