20100066162 | Braking Apparatus For Vehicle - In a braking apparatus for a vehicle, an input piston and a pressurizing piston are movably supported inside a cylinder, thereby sectioning a first pressure chamber, a second pressure chamber, and a third pressure chamber, the second pressure chamber and the third pressure chamber communicating with each other through a communicating path. An ECU causes a control hydraulic-pressure that is adjusted by first and second liner valves to act on the second pressure chamber from the third pressure chamber, thereby assisting the pressurizing piston to enable to output control hydraulic-pressure from the first pressure chamber. A counterforce chamber whose volume decreases as the input piston moves forward is provided inside a cylinder, and a counterforce giving mechanism that can give an operation counterforce to a brake pedal through the input piston by deforming corresponding to decrease of the volume of the counterforce chamber is provided inside the input piston. | 03-18-2010 |

20100295364 | BRAKE SYSTEM COMPRISING A CLUTCH SHIFTABLE BY THE BRAKE PEDAL FOR DISENGAGING THE DRIVE DEVICE FROM THE PISTON-CYLINDER UNIT - The invention relates to a brake system, comprising at least one piston-cylinder unit for producing a pressure in at least one working chamber, the working chamber being connected to at least one wheel brake via at least one hydraulic line, and the brake system comprising at least one drive device and an actuating device, particularly in the form of a brake pedal, and the drive device during normal operation acting on the at least one first piston of the piston-cylinder unit for building pressure and reducing pressure by way of a first force transmission means, and in the event of failure of the drive device the actuating device acting mechanically on the piston by way of a second force transmission means, wherein the adjustment of the second force transmission means disengages the connection between the first force transmission means and the piston by means of the actuating device. | 11-25-2010 |
20110006595 | CONTROL SYSTEM FOR AUTOMATIC RELEASE HAND BRAKE - A hand brake control system for a rail vehicle hand brake having a release trigger. The system includes a cylinder for activating the release trigger of the hand brake and a source of pressure. A first valve selectively connects either the source of pressure at a first input or a second input to the cylinder at an output. A second valve selectively connects either the source of pressure or exhaust to the second input of the first valve at the output of the second valve. The first valve is a manually operated valve and the second valve is an electro-pneumatic valve. Linkage allows actuation of the first valve from at least two location about the vehicle. | 01-13-2011 |
20110006596 | BRAKE SYSTEM COMPRISING AT LEAST ONE CONVEYING UNIT FOR REDELIVERING BRAKE FLUID TO THE WORKING CHAMBERS OF A BRAKE BOOSTER - The invention relates to a brake system comprising an electromotive drive device for a brake booster having at least one piston, the at least one piston being driven by the drive device for pressure build-up and pressure relief in at least one wheel brake and being mechanically adjustable by means of a brake actuator, especially in the form of a brake pedal, only in the event of malfunction of the drive device, at least one decoupling valve for closing and opening the brake line being arranged in the brake line between every wheel brake and a working chamber of the brake booster. The brake system is characterized in that at least one delivery unit delivers, when required, brake fluid from a reservoir to the respective working chamber of the brake booster via at least one supply line that is connected to a brake line or the brake booster, especially to a working chamber, a controlled valve for opening and closing the respective supply line being arranged in every supply line. | 01-13-2011 |

20110248560 | Method For Controlling A Hydraulic Vehicle Brake System - A method for controlling a hydraulic vehicle brake system having an electromechanical brake booster, includes activating the brake booster and a master brake cylinder of the vehicle brake system in response to a desire to brake, and reducing a clearance in the wheel brakes. | 10-13-2011 |
20110278914 | BRAKE ACTUATOR, METHOD OF OPERATING SAME, AND SYSTEM INCLUDING SAME - A brake actuator includes an actuator body, a piston held in the actuator body, and an actuator rod coupled to the piston and coupleable to a brake to actuate the brake. A method of operating the brake actuator includes maintaining a first fluid pressure of a first fluid against a first side of the piston to urge the piston in a brake-actuating direction, and controlling a second fluid pressure of a second fluid against a second side of the piston opposite the first side of the piston to move the piston controllably in a brake-releasing direction. A brake system including the brake actuator is also disclosed. | 11-17-2011 |
