Definitions

  • the present invention relates to a brake device for a rotating body and a moving body control device.
  • Brake devices for vehicles such as automobiles and railcars are equipped with a rotating plate (disk brake rotor) attached to the rotating shaft of the wheels to reduce the output of a driving device (engine) for rotating the wheels, A friction member (brake pad) is brought into contact with the rotating plate, and the rotational speed of the rotating shaft is reduced by friction between the rotating plate and the friction member, thereby decelerating the vehicle.
  • a rotating plate disk brake rotor
  • a friction member brake pad
  • the brake device using the friction body has various problems as described below.
  • the brake pad is brought into contact with the disk brake opening by depressing the brake pedal with a foot, the occurrence of a shock due to a sudden braking force is prevented, and The brake pedal and brake pad are oiled to reduce the impact on the foot due to the contact between the brake pedal and the disk brake rotor. If the frictional heat acts on the oil in the hydraulic circuit, air bubbles are generated, causing a phenomenon that the braking force is significantly reduced. The surface is thermally expanded and deformed, or the friction surface is blunted, causing a phenomenon (fade phenomenon) in which the friction force, that is, the braking force is reduced.
  • This repulsive force is proportional to the square of the rotational speed of the disk brake rotor (ie, kinetic energy).
  • the repulsive force is small.
  • the braking force due to the friction is exerted satisfactorily, but when the rotation speed of the disk brake rotor is higher than a certain level, the repulsive force described above increases dramatically, and the braking force due to the friction is exerted favorably. Disappears.
  • the rotational speed of the friction body must be a rotational speed corresponding to the rotational speed of the rotating plate. This is because, for example, if the rotational speed of the friction body is constant, the rotating plate cannot naturally become lower than the rotational speed of the friction body, and moreover, as the rotational speed of the rotating plate approaches the rotational speed of the friction body. However, as the difference between the two rotational speeds becomes smaller, the frictional force, ie, the braking force, decreases. Further, in the configuration in which the friction member has a constant rotation speed, the problem of the repulsive force occurs when the rotation speed of the rotating plate (that is, the rotation speed of the wheels) is more than a certain degree.
  • the rotation speed of the friction body must be adjusted in accordance with the rotation speed of the rotary plate. For example, if the friction body is rotated by an appropriate motor, this adjustment is very troublesome. This is because a detection device for detecting the rotation speed of the rotating plate is required, and a variable device for appropriately changing the rotation speed of the friction body is required. Furthermore, the use of such a detecting device or a variable device causes a problem that the responsiveness (response) of the brake is deteriorated.
