Patent application number | Description | Published |
20080290726 | Brake system - A brake system includes a tandem-type master cylinder, a tandem-type slave cylinder with front and rear fluid pressure chambers and front and rear pistons arranged such that fluid pressure is generated in the fluid pressure chambers when the rear piston is advanced by an actuator, wheel cylinders connected to the fluid pressure chambers of the master cylinder, respectively, and a regulator which regulates a maximum distance between the front and rear pistons. The regulator prevents excessive increase in the volume of the rear fluid pressure chamber. | 11-27-2008 |
20090095100 | Brake apparatus - Brake apparatus includes a transmission unit for operatively connecting a brake pedal to a master cylinder, and the transmission unit is a mechanism capable of varying a ratio between an output amount of a push rod connected to a master cylinder and an operation amount of the brake pedal. Further, the transmission unit is constructed in such a manner that, in an initial operation region of the brake pedal, a ratio of the operation amount of the brake pedal to the output amount of the push rod is set to be greater than in another operation region immediately following the initial operation region. | 04-16-2009 |

20130291533 | VEHICLE-BODY ATTACHMENT STRUCTURE FOR ELECTRIC BRAKE ACTUATOR - Untreated bosses are formed in advance in two directions on a cylinder mechanism. The bosses on one side are formed as mounts to attach a motor cylinder device to a vehicle body, and the other bosses are formed as ports to connect to the cylinder mechanism. The mount bosses are formed on the outside in the width direction of the vehicle, and the port bosses are formed on the inside in the width direction of the vehicle. | 11-07-2013 |
20130333375 | VEHICLE BRAKE SYSTEM - The following are provided: an input device via which an operator inputs brake operations; a motor cylinder device that generates hydraulic brake pressure on the basis of electric signals based on said brake operations; and a VSA device that assists in stabilizing the behavior of the vehicle on the basis of the aforementioned hydraulic brake pressure generated by the motor cylinder device. Said input device, motor cylinder device, and VSA device are disposed, separated from each other, in an engine compartment partitioned off forwards of a dashboard. | 12-19-2013 |
20130340422 | VEHICLE-BODY ATTACHMENT STRUCTURE FOR ELECTRIC BRAKE ACTUATOR - 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. | 12-26-2013 |
