  • Patent number: 11072317
    Abstract: A brake fluid reservoir for a hydraulic brake actuator of vehicles, which is coupled at its lower base to the upper side of the hydraulic module of the hydraulic brake actuator. The reservoir includes at its lower base a mechanical anchor, which fastens it to the hydraulic module and includes a single anchoring point, which is centered at the lower base of the reservoir in the longitudinal direction. The reservoir also includes several connecting nipples, which may be connected to the hydraulic module with the aid of sealing washers, which generate a torque on the reservoir in relation to the mechanical anchor. The reservoir includes a compensation seal, which is situated in a receptacle of its lower base in such a position that it generates an additional torque in relation to the mechanical anchor, which compensates for the torque generated by the plurality of connecting nipples.

  • Publication number: 20210206363
    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.

  • Publication number: 20210188232
    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.

  • Publication number: 20210086730
    Abstract: A hydraulic block of a slip regulation system of a hydraulic external force vehicle brake system that has a master brake cylinder bore and forms a master brake cylinder. In order to prevent a hard impact of a master brake cylinder piston on an end stop when the master brake cylinder is released, in particular when there is a sudden release, for example when the driver's foot slips off the brake pedal, the present invention provides a hydraulic return flow damper that is integrated in the master brake cylinder piston.

  • 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.

  • Publication number: 20200282968
    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.
