20090114865 | Solenoid-valve unit for an electropneumatic controller - A solenoid-valve unit for an electropneumatic controller, especially a pilot-control unit of an electropneumatic pressure modulator of a vehicle, includes a solenoid-valve unit having a valve-housing bottom with compressed-air bores, and solenoid valves having solenoids and displaceable magnet armatures. The solenoids are disposed outside of the valve-housing bottom. At least one pressure sensor for measuring pneumatic pressure in a compressed-air bore of the valve-housing bottom is placed in or on the valve-housing bottom. Electric leads to the solenoids and to the pressure sensor are routed to a common electrical interface. | 05-07-2009 |
20090184568 | Electro-Pneumatic Brake Control Device - An electro-pneumatic brake control device is provided for controlling the parking brake of a vehicle having compressed-air-actuated brake cylinders, at least one of which is a spring brake cylinder with a spring store part. Valve devices place the brake control device into various operating states. In a first operating state, the valve devices are at least partially supplied with current and switched such that a compressed air line to the spring store part of the spring brake cylinder is aerated. In a second state, the valve devices are at least partially supplied with current and switched such that the compressed air line is deaerated. In a third state, which can be activated in the event of failure of the electrical energy supply of the brake control device, the valve devices are switched to a currentless state such that the compressed air line is automatically deaerated in throttled manner. | 07-23-2009 |

20090309413 | VALVE UNIT, ELECTRO-PNEUMATIC BRAKE CONTROL DEVICE HAVING A VALVE UNIT OF SAID TYPE FOR CONTROLLING A PARKING BRAKE, VEHICLE BRAKE SYSTEM HAVING A BRAKE CONTROL DEVICE OF SAID TYPE AND VEHICLE HAVING A BRAKE SYSTEM OF SAID TYPE - A valve unit for an electro-pneumatic brake control is connected to an input of an air-quantity-boosting valve for the aeration/venting thereof. A double-armature solenoid valve includes primary and secondary armatures each spring-loaded and actuated by common magnet coil. The primary armature is a switch for a vent valve; the secondary armature is a switch for an intake valve. When the coil is not drawing current, the armatures are in spring-loaded position, the intake valve blocking intake and the vent valve venting. When a first current flows through the coil, the primary armature enters switching position, with the secondary armature in spring-loaded position; the intake valve blocking intake and the vent valve blocking venting. When a second current greater than the first flows through the coil, both primary and secondary armatures are moved into switching positions, so that the intake valve admits air and the vent valve blocks venting. | 12-17-2009 |
20100025141 | Electro-Pneumatic Brake Control Device - An electro-pneumatic brake control device is provided for controlling a parking brake of a vehicle having a service brake and a parking brake, the service brake having a brake pedal and pneumatically actuatable brake cylinders operatively connected to the brake pedal for actuating wheel brakes. At least one brake cylinder is a spring brake cylinder with a spring store part for actuating the parking brake. In the event of a failure of the electrical energy supply, the spring store part of the spring brake cylinder is permanently vented by actuating the brake pedal in order to activate the parking brake. | 02-04-2010 |

20120006634 | Actuating Device and Method for Actuating Such an Actuating Device - The invention relates to an actuating device for a parking brake of a vehicle, in particular a commercial vehicle, wherein the actuating device comprises an operating brake for driving operation and the parking brake for securing the vehicle. A first braking effect can be generated by means of the parking brake for the vehicle independently of a braking procedure for the operating brake. The actuating device comprises a first switched state, wherein the first braking effect of the parking brake cannot be provided, and comprises a second switched state, wherein the first, in particular full, braking effect and the parking brake can be provided. The actuating device further comprises a manually actuatable operating element ( | 01-12-2012 |
20130214588 | Valve Device, Brake System and Vehicle - A valve device for brake control of a different pressure medium-operated vehicle brake systems comprises a housing that has pressure medium ducts. A relay valve provides a pneumatic control pressure, which is fed to the relay valve via at least one of the pressure medium ducts at a higher flow rate. At least one insert is pneumatically connected to at least two of the pressure medium ducts, which can be pneumatically connected to each other by the insert. The two pressure medium ducts define a pressure medium path, the profile of which differs based on the housing that is in each case selected and/or switched based on the selected insert. The housing is selected from a set of housings having different pressure medium ducts, in particular bores, but which are otherwise essentially similar. The insert is selected from a set of different inserts. | 08-22-2013 |
