Abstract: An actuation device for a hydraulic actuation system, e.g., a motor vehicle brake or an electrified clutch actuator, may include a connection for an actuation device; a pressure supply device, driven by an electromotor drive, in the form of a piston or double-stroke piston pump; a piston cylinder unit that may be actuated by means of the actuation device; and an electronic control unit. An axis of the piston cylinder unit and an axis of the pressure supply device may be arranged in parallel.

Abstract: A brake system may include a first pressure supply unit having an electromotive drive and arranged to supply pressure medium to first and second brake circuits; a motor-pump unit to supply pressure medium to at least one of the brake circuits; a second pressure supply unit, connected to the motor-pump unit via first and second hydraulic lines and arranged to supply pressure medium to at least one of the brake circuits; and a valve unit. The second pressure supply unit may be connected via a third hydraulic line to at least one of the brake circuits. The valve unit may include at least one feed valve via which the third hydraulic line may be at least partially reversibly shut off. An isolating valve may be disposed in at least one of the hydraulic lines to at least partially reversibly shut off the at least one hydraulic line.

Abstract: A vehicle brake system may include: two hydraulic brake circuits, each having at least one hydraulically operating wheel brake; first and second pressure supply devices; at least one valve assembly for adjusting the brake pressure for each wheel individually and/or for separating/connecting the wheel brakes from/to at least one of the pressure supply devices; at least one electronic control and regulating unit; and a hydraulic connection line connecting the two brake circuits. Each wheel brake is paired with a dedicated switch valve, and each brake circuit has a hydraulic main line via which the switch valves may be connected to the pressure supply devices. The connection line has two connection switch valves connected in series and open when unenergized via pressure present in the respective hydraulic main line and/or an inner section of a connection line connecting two connections of the connection switch valves directly together.

Abstract: A braking system for a vehicle may include a hydraulic brake pedal system having a master cylinder having at least one pressure chamber, from which a hydraulic output is coupled to at least one brake circuit via an infeed switch valve. The master cylinder is coupled to a reservoir via at least one opening via a hydraulic connection. A failure of a pressure chamber seal of the at least one pressure chamber of the master cylinder is safeguarded by at least one redundancy, and the failure of the pressure chamber seal or the redundancy of the pressure chamber seal of the at least one pressure chamber of the master cylinder can be diagnosed.

Abstract: A helical gearing for driving an adjusting element, which may be an actuator or a piston of a piston-cylinder unit, is driven by an electric motor. The adjusting element may be moved along an axis. The drive apparatus has a rotor, or a translator rotatably mounted in a housing by a bearing and fixedly connected to the input of or formed integrally with the helical gearing. The output of the helical gearing is connected to or formed integrally with the adjusting element. An anti-twist means may prevent the adjusting element from twisting in the circumferential direction about the axis. The helical gearing and/or at least part of the adjusting element is/are formed to be transversely elastic to the axis of rotation, at least in one region.

Abstract: The disclosure 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. 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 of the piston-cylinder unit.

Abstract: A brake system may include an actuation device, in particular a brake pedal; a first piston-cylinder unit with two pistons, in particular an auxiliary piston and a second piston, in order to supply brake circuits with a pressure medium via a valve device, wherein one of the pistons, in particular the auxiliary piston, can be actuated by means of the actuation device; a second piston-cylinder unit comprising an electric motor-powered drive, a transmission, and at least one piston in order to supply pressure medium to at least one of the brake circuits via a valve device; and a motor pump unit with a valve device in order to supply pressure medium to the brake circuits. The brake system may further include a hydraulic travel simulator which is connected to a pressure or working chamber of the first piston-cylinder unit.

Abstract: A brake system and a method for controlling a brake system. The brake system may include a first module having a first pressure supply unit with an electromotive drive, an optional second pressure supply unit and a first control device for controlling the first pressure supply unit; a second module having a third pressure supply unit, isolation valves and brake-pressure-adjusting valves, and a second control device for controlling the brake-pressure-adjusting valves; and a detection unit for detecting a first case of error. The brake system is designed such that, in the first case of error, in order to provide an ABS function and/or a yaw torque intervention, it implements a (wheel-specific and/or selective) adjustment of the pressures in the wheel brakes by actuating at least one of the brake-pressure-adjusting valves of the second module and/or the isolation valves of the second module and the first pressure supply unit.

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.

Abstract: A brake system for a vehicle has at least one pressure supply device which is connected to a brake circuit via a hydraulic line. Furthermore, the brake system has a hydraulic connection between at least one of the brake circuits and an accumulator container, said connection being switchable via at least one outlet switch valve, and the pressure supply device has a double stroke piston with a working stroke and a return stroke. The double stroke piston can be at least partly emptied via the outlet switch valve.
