  • Patent number: 9545905
    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.

  • Patent number: 9290170
    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.

  • Patent number: 8960049
    Abstract: The purpose of the present invention is to provide a vehicle brake system having a high degree of mounting freedom. The present vehicle brake system is configured in such a manner that an input device into which braking operation of the operator is inputted and a motor cylinder device which generates hydraulic brake pressure on the basis of an electric signal according to at least the braking operation are disposed so as to be separated from each other in the engine room partitioned in front of the dashboard. The vehicle brake system is characterized in that the input device is disposed behind a power device in such a manner that at least a part of the input device overlaps the power device in the front-rear direction.

  • Patent number: 8827378
    Abstract: Brake apparatus (10; 110; 140) includes a transmission unit (75) for operatively connecting a brake pedal (12) to a master cylinder (17), and the transmission unit is capable of varying a ratio between an output amount of a push rod (86) connected to a master cylinder (17) and a movement amount of the brake pedal (12). Further, the transmission unit (75) is constructed such that, in a latter-half operation amount region (E2; E6; E9) of the brake pedal, the ratio of the operation amount of the brake pedal to the movement amount of the push rod is controlled, via the transmission unit, to increase in response to increase of the operation amount of the brake pedal.
