摘要:
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.

An input device of a vehicle brake system integrally includes an integrally provided master cylinder 34 and a stroke simulator 64 which communicate via a hydraulic communication path. The stroke simulator 64 is provided with a simulator piston 68 accommodated within a simulator accommodation chamber 64c. The simulator accommodation chamber 64c has an opening portion 64e enabling the insertion of the simulator piston 68 into the simulator accommodation chamber 64c from the side on which the brake pedal is disposed relative to the dashboard 2.

The following are provided: an input device (14) via which an operator inputs brake operations; a motor cylinder device (16) that generates hydraulic brake pressure on the basis of electric signals based on said brake operations; and a VSA device (18) that assists in stabilizing the behavior of the vehicle on the basis of the aforementioned hydraulic brake pressure generated by the motor cylinder device (16). Said input device (14), motor cylinder device (16), and VSA device (18) are disposed, separated from each other, in an engine compartment (R) partitioned off forwards of a dashboard (2).
摘要:
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.
