  • Braking system including motor-driven disc brake equipped with self-servo mechanism
    Patent number: 6305506
    Abstract: Electrically operated braking system with a motor-driven disc brake including an electric motor for braking an automotive vehicle wheel, and a motor control device controlling the electric motor, the disc brake further including a disc rotor having a friction surface, a friction pad movable for contact with the friction surface to restrict rotation of the disc rotor, a pad support mechanism for supporting the friction pad movably in a direction intersecting the friction surface, a pad pressing mechanism including the electric motor and a pressing member, the electric motor producing a drive force for moving the pressing member to force the friction pad against the disc rotor, and a self-servo mechanism for providing a self-servo effect of boosting a friction force generated between the friction surface and the friction pad, on the basis of the friction force.
