  • Publication number: 20140026557
    Abstract: An electric brake device includes a first slave piston which is housed in a cylinder body and generates hydraulic pressure in a first hydraulic chamber by moving forward, a motor which transmits a driving force to the first slave piston, and a restriction pin which is inserted and secured to the cylinder body in a direction perpendicular to an axial direction of the cylinder body and restricts a backward position of the first slave piston when a hydraulic pressure is applied from an outside to the first hydraulic chamber, wherein the restriction pin is inserted and secured to the cylinder mechanism in the direction perpendicular to the axial direction of the cylinder main body. Further, a clearance is formed between an inner peripheral wall of the cylinder body and a first groove portion and second groove portion which are formed on an outer surface of the restriction pin.

  • Publication number: 20140000254
    Abstract: A vehicular hydraulic-pressure-generation device wherein a first bush compressively deforms due to pressure from a simulator piston that moves when hydraulic pressure produced when a brake pedal is depressed is transmitted into a cylinder part. Said vehicular hydraulic-pressure-generation device thus creates artificial reaction-force characteristics with respect to the position of the brake pedal. The aforementioned first bush has a third elastic modulus, which is smaller than a second elastic modulus, and is provided in parallel with a first return spring. The compressive deformation of the first bush occurs over a second region that overlaps a first region in which compressive deformation of the return spring primarily occurs. This makes the brake pedal move more smoothly, reducing the feeling of incongruity resulting from a V-shaped singularity in the reaction-force characteristics with respect to brake pedal position.

    Abstract: A structure for attaching a motor cylinder device to the body of the vehicle, said vehicle brake system including: an input device via which an operator inputs brake operations; and a motor cylinder device that generates hydraulic brake pressure on the basis of electrical signals based on said brake operations. Said motor cylinder device has: an electric motor that operates on the basis of electrical signals; a driving-force transmission unit that transmits driving force from the electric motor; and a cylinder mechanism that applies pressure to a brake fluid by moving a piston axially by means of the driving force transmitted by the driving-force transmission unit. A mount for attaching the motor cylinder device to the body of the vehicle is provided near the center of gravity of the motor cylinder device. This makes it possible to minimize displacement of the electric brake actuator when subjected to vibration.
