Abstract: The invention relates to an actuating system for a vehicle brake, with an actuating arrangement, in particular a brake pedal, at least one (first) piston-cylinder unit, which is connected via a hydraulic line to the vehicle brake (braking circuit) in order to supply the braking circuit with pressure medium and apply pressure to the vehicle brake, and with a drive for the piston-cylinder unit. According to the invention, pressure medium can be fed to the braking circuit in controlled manner in both piston movement directions, in particular the advance stroke and the return stroke, by means of at least one, in particular stepped, piston (10) of the piston-cylinder unit (10, 10a, 10b).

Abstract: 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.

Abstract: An actuation device for a hydraulically operating brake system may include: a master cylinder in a housing and having at least one piston, to which a force can be applied by, e.g., a brake pedal; pressure supply device(s), at least one of which is a piston pump or double stroke piston pump having a piston and driven by an electromotive drive, the drive moving the piston directly or via a step-up gear; at least one valve assembly with magnetic valves; and at least one electronic control and regulating unit. The brake system has at least two hydraulic circuits, and a pressure change can be carried out in at least one wheel brake via the pressure supply device(s). A first housing or module, hydraulically connected to the housing, may contain the valve assembly and the at least one piston and pressure chamber of at least one of the pressure supply devices.

Abstract: An actuating device for an entirely or partially hydraulic vehicle braking system includes a master brake cylinder with a piston and a working chamber hydraulically connectable to a reservoir, a pedal feel simulator, and, via at least one normally open valve, at least one brake circuit. At least one hydraulic wheel brake is assigned to a brake circuit and connected thereto via at least one separate controllable switching valve. A pressure supply unit has a motor-driven piston and a cylinder. At least one valve assembly includes wheel-specific solenoid pressure control valves. At least one electrical control unit controls valves of the valve assembly and the motor of the pressure supply unit. Outlet valves enable discharge of hydraulic medium from wheel brakes or brake circuits into the reservoir. One housing contains the valve assembly and hydraulic component of the pressure supply unit, and a separate housing contains the master brake cylinder.

Abstract: A brake system for a vehicle has at least two hydraulic brake circuits, each with at least one hydraulically acting wheel brake, and a switching valve on each hydraulically acting wheel brake, which switching valve connects in each case one hydraulically acting wheel brake to one of the two brake circuits. The brake system also has a central outlet switching valve which brings about a switchable hydraulic connection between at least one of the brake circuits and a reservoir vessel, wherein the reduction in pressure in the at least one hydraulically acting wheel brake is effected by opening the central outlet switching valve and the associated switching valve.
