  • Publication number: 20260241906
    Abstract: An electrically controllable solenoid valve, in particular for open-loop and/or closed-loop control of a pressure medium connection in a hydraulic unit of an electronically slip-controllable vehicle brake system. Some solenoid valves have a valve insert including a lower part with a control cross-section and an upper part for guiding a tappet. A closing element is coupled to the tappet for controlling the control cross-section. To actuate the valve, a magnetic coil acts on a magnetic armature, which actuates the tappet against the force of a return element. The lower part has an end portion which is inserted into a lower part receptacle in the upper part. The end portion includes at least one recess which is open toward the upper part and penetrates a wall of the lower part in radial direction.

  • Publication number: 20260233724
    Abstract: A method for controlling a wheel-specific electrohydraulic brake actuator, a wheel-specific electromechanical brake actuator, and an electronically slip-controllable power braking system with a wheel-specific electrohydraulic brake actuator. Brake actuators are provided with a housing block. A motor is arranged thereon for actuating a brake pressure generator, a pressure medium reservoir, a pressure channel from the brake pressure generator to a wheel connection for a wheel brake, and an electronic control unit. A method provides for controlling a brake actuator, in which the driving of the brake pressure generator is controlled by the electronic control unit to regulate the pressure at the wheel connection and the pressure channel can be controlled using an electrically actuatable isolating valve which is controlled by the electronic control unit at least for pressure reduction in such a way that it assumes an open position.

  • Patent number: 12420757
    Abstract: A hydraulic unit for an electronically slip-controllable power brake system of a motor vehicle. A cuboidal housing block is equipped with components for generating a braking pressure and for open- or closed-loop control thereof. On a motor side of the housing block, a motor is fastened to drive a braking pressure generator, while on a reservoir side, a reservoir is provided to supply the vehicle brake system with a pressure medium. The reservoir has at least one protruding fastening peg, which projects into a recess open to the outside on the housing block. Using a retaining pin inserted into a transverse bore of the housing block and passing through this recess, the reservoir is anchored to the housing block. The transverse bore, open on the motor side of the housing block, is in a flat portion in which a pin head of the retaining pin lies without the pin head protruding axially beyond a motor side of the housing block.

  • Publication number: 20250263054
    Abstract: A hydraulic block of a power brake system, which is designed as a cuboidal housing block. The hydraulic block has a power cylinder bore for receiving a power cylinder, and two chambers, which are arranged above the power cylinder bore and form a brake fluid reservoir. On a side of the power cylinder bore that is opposite to the brake fluid reservoir, a separating cylinder is arranged, which extends perpendicularly to the power cylinder bore and in which a separating piston is arranged, which hydraulically separates a first and a second supply connection to a vehicle dynamics control from one another. The separating cylinder is hydraulically connected to the power cylinder so that pressure of the power cylinder can be applied to a first axial piston side of the separating piston and a brake pressure can be generated via a second axial piston side of the separating piston.
