摘要： An internal planetary gear mechanism reduces a load applied to tooth surfaces of an external gear and an internal gear, a sliding portion such as a bearing and the like. By setting the amount of eccentricity α of an eccentric part to be larger than a theoretical value, a distance between the center of the external gear and the center of the internal gear is increased to allow the reduction of a loss in the bearing and on the tooth surfaces of the gears, and a mesh zone between the internal gear and the external gear can be reduced to decrease a part at a large pressure angle, thereby reducing a loss generated by a large pressure angle. As a result of reduction in the mesh zone between the external gear and the internal gear, rolling contact of the gears is maintained.

摘要： In a vehicle brake apparatus for executing ABS control to prevent a wheel from locking in such a manner that braking force is controlled so as to keep a slip ratio of a wheel at a target slip ratio so that an excessive drop of a wheel speed from a vehicle body speed is adjusted, an output current for driving a braking actuator is set to a current on which oscillating waves are superimposed during ABS control so that the wheel speed changes to show oscillating waves. Even if the wheel speed once drops to an extent that the slip ratio exceeds the target slip ratio, further decrease of the wheel speed is restricted and the wheel speed turns to an increase soon and this cycle is repeated. Accordingly, there occurs no excessive drop of the wheel speed due to the response delay so that sufficient braking force is generated.

摘要： An eccentric portion of a first shaft is supported by a pair of roller bearings. If moments are generated by meshing of an externally toothed gear and an internally toothed gear and inner pins and inner pin holes that configure a rotation control mechanism, the pair of bearings provide two point support for the externally toothed gear. Accordingly, the externally toothed gear is supported so as not to tilt with respect to the first shaft, and a configuration is provided in which point contact does not occur in the meshing area of the externally toothed gear and the internally toothed gear.

摘要： The present invention provides an electric brake system which detects the occurrence of overshooting, and corrects a feedback gain in the PID feedback control at overshooting. For example, it increases a differential gain Kd. Accordingly, a damping force increases from the time when the overshooting is determined, and after the overshooting, the output of an electric brake moderately decays to get closer to the target value with the passage of time.

摘要： A vehicular motor-driven brake apparatus includes an open circuit in which reciprocation of a master cylinder generating a brake pressure is caused by an actuator that operates according to a pedal operation amount, and brake fluid discharged from a wheel cylinder during pressure decrease is directly returned to a master reservoir subject to atmospheric pressure. A fluid amount replenishment control is executed during pressure increase of the master cylinder in which a master stroke is returned for only a predetermined time by operation of the actuator, and thus brake fluid is sucked up from the master reservoir to the master cylinder. Accordingly, when an ABS control continues for a long time period, even if the brake pedal is being depressed, reduced pressure brake fluid in the master cylinder is sucked up. Therefore, there is no limit to pressure decrease, and bottoming-out of the master cylinder does not occur.
