Definitions

  • the two first wheel valves which can be hydraulically separated from the first pressure source, are preferably assigned to the wheels of a first vehicle axle, while the other first wheel valves are assigned to the wheels of another vehicle axle.
  • the first vehicle axle is the front axle and the other vehicle axle is the rear axle.
  • the brake system comprises a first electronic device, by means of which the first pressure source is actuated, and a second electronic device, by means of which the second pressure ⁇ source is actuated.
  • the second electronic device is electrically independent of the first electronic device, so that an electrical or electronic fault in one of the electronic devices does not lead to failure of both electronic devices.
  • an output port of the first wheel valve 6a, 6b, 6c, 6d and an output port of the second wheel valve 7a, 7b, 7c, 7d are interconnected and connected to the wheel brake.
  • the input terminals of the second wheel valves 7a-7d are directly hydraulically connected via the second brake supply line 33 to the second pressure source 2 or the pressure space thereof.
  • "Directly hydraulically connected” is to be understood here in the sense that no electrically operable valve or even no valve (eg check valve) is arranged in the second brake supply line 33. Thus, it is neither a circular valve for separating the second pressure source from a part of the wheel brakes nor provided a separating valve for separating the second pressure source of all wheel brakes.
  • check valve before ⁇ is seen.
  • a check valve opening in the direction of the brake supply line 33 is provided.
  • the said check valves are usually part of the piston pump.
