Abstract (en)
[origin: WO2009138075A1] The invention relates to a hydraulic brake system (1), comprising at least one brake valve (4, 98, 100), which can be manually actuated and by way of which a pressurized medium connection between at least one brake line (53, 54) connected by way of a pressurized medium connection to a wheel brake cylinder (26, 28, 30, 32) and a hydraulic accumulator (6, 8) can be opened. To this end, a wheel valve (16, 18, 20, 22, 102, 176, 178, 180, 182) is disposed between the wheel brake cylinder (26, 28, 30, 32) and the brake valve (4, 98, 100) in the pressurized medium flow path, wherein said wheel valve can be controlled by way of a circuit valve (34, 36, 184, 186, 210, 212) or a control element actuating the brake valve (4, 98, 100), regardless of the manual actuation of the brake valve (4, 98, 100). A plurality of brake circuits (94, 96) can be provided in the brake system, each being associated with a circuit valve 34, 36, 184, 186, 210, 212). The wheel and brake valves are furthermore either electrically controlled or pilot-controlled by hydraulics.
