BRAKE SYSTEM WITH AT LEAST TWO HYDRAULIC CIRCUITS AND AT LEAST TWO PRESSURE SUPPLY DEVICES

A brake system may include: two hydraulic brake circuits, each having at least one wheel brake; a first pressure supply device for pressure build-up and release in at least one brake circuit via forward and return travel of a piston; a second pressure supply device with a continuous delivery, electromotively-driven piston pump, gear pump, or eccentric piston pump; at least one valve assembly with valves for adjusting pressure for each wheel brake and/or for connecting/disconnecting the wheel brakes and at least one of the pressure supply devices; at least one electronic control unit; a connection line connecting the two brake circuits; and at least one outlet valve for pressure release. The wheel brakes are paired with dedicated switch valves. Each brake circuit has a hydraulic main line to connect the switch valves to the first and second pressure supply devices, which provide different maximum pressures and/or delivery volumes.
