  • Patent number: 11767000
    Abstract: A cuboidal hydraulic block of a hydraulic power unit of a hydraulic power vehicle braking system for use in a left-hand drive vehicle or a right-hand drive vehicle to be attachable, rotatably by 180° about a horizontal axis, at a splashboard of a motor vehicle. An electric motor of a power brake pressure generator is thus selectively situated on a right or a left side of the hydraulic block.

  • Patent number: 11639161
    Abstract: A pedal-travel simulator of a hydraulic power vehicle brake system is connected to a brake-fluid reservoir by way of a groove between two piston seals of a power brake-pressure generator. Any air bubbles in the brake fluid get out of the pedal-travel simulator into the brake-fluid reservoir, and the piston seals are lubricated with the brake fluid.

  • Patent number: 11220250
    Abstract: A hydraulic block for a hydraulic power vehicle brake system including a slip control. A bore, which communicates through a circumferential groove with a receptacle of a pedal travel simulator, is run through parallel to a motor side of the hydraulic block between the motor side and a master brake cylinder bore in the hydraulic block and is connected through a transverse bore with a further bore parallel to the motor side, which connects the master brake cylinder bore with a connection for a pressureless brake fluid reservoir, which is attachable to the hydraulic block. The bores form a return of the pedal travel simulator, which has a low resistance to flow and allows for a closed system.

  • Publication number: 20210070267
    Abstract: An electrohydraulic vehicle power braking system for a passenger car driving autonomously on public roads. Two power brake pressure generators are provided which are independent of one another, one of which preferably includes an electromechanically drivable power piston-cylinder unit, and the other preferably includes two hydraulic pumps. Each power brake pressure generator includes a brake fluid reservoir, which is divided into chambers and which together are connected to a further brake fluid reservoir, which is not divided into chambers. The further brake fluid reservoir includes a brake fluid sensor, with the aid of which a brake fluid loss due to a leak at any arbitrary point of the vehicle power braking system is establishable. Due to short lines, the brake fluid reservoirs cause low flow resistances, and thus a rapid brake pressure build-up, even when the brake fluid is cold and, as a result, viscous.

  • Patent number: 10625722
    Abstract: A method for producing a hydraulic block of a slip-controlled hydraulic non-muscular-energy vehicle brake system. For the milling operation, the hydraulic block is clamped in two setups and a pump bore, into which the hydraulic block is clamped in the second setup, is produced in the hydraulic block in the first setup, thereby making it possible to machine five sides of the hydraulic block in the second setup free of clamping arrangement. Also described is a related hydraulic block.
