  • Publication number: 20170008365
    Abstract: A stabilizer bushing includes a holding hole, a vehicle-body facing surface, an outer surface having a U-shape, and at least one separation surface extending from an inner circumferential surface of the holding hole to the outer surface. Each of the at least one separation surface has a pressing force generating surface located nearer to the vehicle-body facing surface than a particular plane in a state in which the stabilizer bushing is mounted on a vehicle-body-side mount surface of a vehicle-body-side component. The particular plane has a central axis of the holding hole and is parallel with the vehicle-body-side mount surface. The pressing force generating surface has a holding-hole-side end portion and an outer-surface-side end portion. The pressing force generating surface is inclined so as to be farther from the vehicle-body-side mount surface at the outer-surface-side end portion than at the holding-hole-side end portion.

  • Patent number: 6469468
    Abstract: An SR motor includes a stator having a plurality of salient poles and a rotor having another plurality of salient poles. Windings are wound around the plurality of salient poles and magnetic fields are generated in the plurality of salient poles. The number of salient poles of the rotor is determined depending upon a number of the salient poles of the stator. A supply mode for supplying power from a power supply to the windings, a reflux mode for setting both terminals of the windings to an identical potential, and a regenerative mode for recovering an electromotive force generated in the windings into the power supply are executed as the rotor rotates. The reflux mode and the regenerative mode are preferably repeated in a period during which the inductance of the windings is reduced as the rotor rotates.

  • Patent number: 6397981
    Abstract: An electromechanical brake system for a vehicle has a brake actuator installed to each wheel of the vehicle and a controller for controlling an operation of each brake actuator. The brake actuator is constituted to clamp a disc rotor by a pair of brake pads through a rotational motion converting mechanism according to an operation of the motor. The rotational motion converting mechanism is constituted by a screw shaft integrally connected to a rotation shaft of the motor and a ball screw screwed with the screw shaft and integrally connected to one of the pair of brake pads. When the vehicle is put in a stopping state, the controller drives the motor so that an ordinary use region of the screw shaft, which is contacted with balls of the ball nut during a brake operation, is faced with a lubricant hole formed at an end portion of the ball nut.
