Abstract: An electrohydraulic power vehicle braking system for a motor vehicle driving autonomously on public roads is equipped with two redundant power brake pressure generators so that, in the event of independent driving and a failure of one power brake pressure generator, the other power brake pressure generator is able to decelerate the motor vehicle without driver intervention.

Abstract: A wheel-specific, electrohydraulic brake actuator for controlling the brake pressure of a connectible wheel brake of a motor vehicle in a slip-dependent manner. A method for controlling a wheel-specific, electrohydraulic brake actuator as well as an electronically slip-controllable vehicle brake system using wheel-specific, electrohydraulic brake actuators, are also described. In the brake actuator, a pressure channel connects the brake pressure generator directly to the wheel connection.

Abstract: In a brake actuating device, in particular a vehicle brake system. The brake actuating device includes a housing, in which a piston seat is disposed which is surrounded by a wall and comprises a receiving axis along which a piston to be coupled to a piston rod can be accommodated in the piston seat in an axially displaceable manner. At its end region which is directed toward the piston rod, the piston seat includes a guide section in which a guide element for guiding the piston rests radially against the wall. The guide element is axially held in position by means of a radial groove disposed in the guide section.

Abstract: A piston of a hydraulic power unit of a hydraulic power vehicle braking system including slip control is guided directly, without a cylinder liner, in a cylinder bore of a hydraulic block. The piston is rotatably fixedly and axially displaceably held in a bushing with the aid of an anti-rotation mechanism, which in turn is rotatably fixed at the hydraulic block. A pivot bearing of a worm gear for displacing the piston is fixed at the bushing.

Abstract: A semicircular rotation prevention part for preventing rotation of a piston of a hydraulic unit of an externally-powered hydraulic vehicle brake system. The rotation prevention part is positioned in a congruent widened section at a mouth of a cylinder bore of a hydraulic block of the hydraulic unit and includes axially parallel rotation prevention grooves on its inner circumference, with which shoulders projecting outwards from the piston engage.

Abstract: A hydraulic block for a hydraulic unit for an electrohydraulic dual-circuit power brake system for a motor vehicle which drives autonomously on public roads. Two chambers of a power cylinder bore in the hydraulic block are connected by nonreturn valves and in parallel by bypass lines to chambers of a brake fluid reservoir arranged on the hydraulic block. Further brake fluid may be drawn in when the power cylinder is actuated.

Abstract: A pump assembly for generating pressure in a brake circuit of a controllable power brake system of a motor vehicle. The pump assembly has, as a pressure generator, a piston-cylinder unit in which a piston is actuated with the aid of a piston drive. The piston drive converts a rotational movement, with which a nut of this piston drive is driven, into a translatory movement of a spindle, which is in turn connected to the piston in a rotationally fixed manner. The piston is a steel component in which a plastic deformation at a piston head forms a device for connecting the spindle to the piston in a rotationally fixed manner.

Abstract: Hydraulically separating both brake circuits of an electrohydraulic dual-circuit power brake system. A piston-cylinder unit having two pistons is provided, the first piston of which being displaceable with a first electric motor via a worm gear and the second piston of which being displaced by subjecting it to pressure by the first piston.

Abstract: An electronically slip-controllable power brake system, The system includes pressure-medium-actuable wheel brakes on a first axle and electromechanically actuable wheel brakes on a second axle of a motor vehicle. A hydraulic unit is provided having a brake master cylinder for specifying a braking request by the driver, a simulator coupled thereto for providing haptic feedback to the driver, a first electronic controller for electrically activating a drive motor of a brake pressure generator using external energy, and a pressure modulator for adjusting one wheel-specific wheel brake pressure per pressure-medium-actuable wheel brake. A controllable first pressure medium connection is provided between the brake master cylinder and the simulator and a controllable second pressure medium connection is provided between the brake master cylinder and one of the pressure-medium-actuated wheel brakes.

Abstract: In the field of autonomous driving, a power braking system having two piston-cylinder units, one of which electromechanically generates a hydraulic brake pressure by means of an electric motor and the other of which communicates with the former in such a way that under pressure it generates a brake pressure in a second brake circuit. The second piston-cylinder unit hydraulically separates two brake circuits from each other.

Abstract: To extend a power cylinder bore in a hydraulic block of a power brake system, a cylinder cover, which is in the form of a cylinder tube and is closed at one end, is fastened by means of a circumferential caulking in a fastening groove of the hydraulic block which encloses the power cylinder bore. An interference fit of a fastening flange of the cylinder cover in the fastening groove reliably seals the cylinder cover against the hydraulic block in a pressure-proof manner.

Abstract: A cup-shaped cover of a pedal travel simulator, hydraulic accumulator, or a damper chamber, using a radially resilient connecting ring, which protrudes into a groove of the cover and into an opposing groove of a receptacle of a hydraulic block of a traction slip controller of a hydraulic vehicle braking system, to fasten inseparably at the hydraulic block.

Abstract: An interface device for a component of a functional system of a vehicle brake system for fastening a pedal-travel sensor coupled to the component and for fastening the component on an associated vehicle. The interface device has a first contact surface to be positioned on the component and has a second contact surface to be positioned on the vehicle. The second contact surface is set at an oblique angle with respect to the first contact surface.

The non-return valve has a valve-seat part in the form of an apertured disk, onto which is pressed a valve cage in which a valve ball is disposed as shut-off member and a helical compression spring is disposed as valve spring. A bowl-shaped filter is secured in a depression in the valve-seat part opposite the valve cage.

A method for assembling the hydraulic unit thus configured is also described.
