Beschreibung description
Die Erfindung betrifft einen quaderförmigen Hydraulikblock für ein Hydraulikaggregat einer Schlupfregelung einer hydraulischen Fahrzeugbremsanlage mit den Merkmalen des Oberbegriffs des Anspruchs 1. Schlupfregelungen sind beispielsweise Blockierschutz-, Antriebsschlupf- und/oder Fahrdynamikregelungen/elektronische Stabilitätsprogramme, für die die Abkürzungen ABS, ASR, FDR/ESP gebräuchlich sind. Solche Schlupfregelungen hydraulischer Fahrzeugbremsanlagen sind von Personenkraftwagen und Krafträdern bekannt und werden hier nicht näher erläutert. The invention relates to a block-shaped hydraulic block for a hydraulic unit of a slip control of a hydraulic vehicle brake system having the features of the preamble of claim 1. Slip control are, for example, anti-lock, traction and / or vehicle dynamics control / electronic stability programs for which the abbreviations ABS, ASR, FDR / ESP are in use. Such slip control hydraulic vehicle brake systems are known from passenger cars and motorcycles and are not discussed here.
Stand der Technik State of the art
Kernstück solcher Schlupfregelungen ist ein Hydraulikaggregat, das einen Hydraulikblock aufweist, der mit hydraulischen Bauelementen der Schlupfregelung bestückt und durch Bremsleitungen an einen Hauptbremszylinder angeschlossen ist und an den durch Bremsleitungen eine oder mehrere hydraulische Radbremsen angeschlossen sind. Hydraulische Bauelemente sind unter anderem Magnetventile, Hydropumpen (meistens Kolbenpumpen), Rückschlagventile, Hydro- speicher, Dämpferkammern und Drucksensoren. Der Hydraulikblock ist typi- scherweise ein quaderförmiger Metallblock, der zu einer mechanischen Befestigung und hydraulischen Verschaltung der hydraulischen Bauelemente der Schlupfregelung dient. Verschaltung meint eine hydraulische Verbindung der hydraulischen Bauelemente entsprechend einem hydraulischen Schaltplan der Schlupfregelung. Der Hydraulikblock weist Aufnahmen für die hydraulischen Bauelemente der Schlupfregelung auf. Dabei handelt es sich üblicherweise um zylindrische, meist durchmessergestufte Ansenkungen, Sack- oder Durchgangslöcher, die im Hydraulikblock angebracht sind und in die die hydraulischen Bauelemente vollständig oder teilweise eingebracht, beispielsweise eingepresst sind. Beispielsweise sind Hydropumpen üblicherweise vollständig in ihre Aufnahmen in einem Hydraulikblock eingebracht, wogegen bei Magnetventilen üblicherweise nur ein hydraulischer Teil in eine Aufnahme eines Hydraulikblocks eingebracht ist und ein elektromagnetischer Teil des Magnetventils aus dem Hydraulikblock vorsteht. Durch eine normalerweise kartesische Verbohrung des Hydraulikblocks sind die Aufnahmen entsprechend dem hydraulischen Schaltplan der Schlupfregelung miteinander verbunden. Kartesisch bedeutet parallel oder rechtwinklig zueinander und zu Flächen und Kanten des Hydraulikblocks im Hydraulikblock angebrachte Bohrungen. Bestückt mit den hydraulischen Bauelementen bildet der Hydraulikblock ein Hydraulikaggregat. The core of such slip control is a hydraulic unit having a hydraulic block which is equipped with hydraulic components of the slip control and connected by brake lines to a master cylinder and to which one or more hydraulic wheel brakes are connected by brake lines. Hydraulic components include solenoid valves, hydraulic pumps (mostly piston pumps), check valves, hydraulic accumulators, damper chambers and pressure sensors. The hydraulic block is typically a block-shaped metal block, which serves for mechanical fastening and hydraulic connection of the hydraulic components of the slip control. Interconnection means a hydraulic connection of the hydraulic components according to a hydraulic circuit diagram of the slip control. The hydraulic block has recordings for the hydraulic components of the slip control. These are usually cylindrical, usually diameter stepped countersinks, blind or through holes which are mounted in the hydraulic block and in which the hydraulic components are completely or partially introduced, for example, pressed. For example, hydraulic pumps are usually completely incorporated into their receptacles in a hydraulic block, whereas in solenoid valves usually only a hydraulic part is introduced into a receptacle of a hydraulic block and an electromagnetic part of the solenoid valve protrudes from the hydraulic block. By a normally Cartesian bore of the hydraulic block recordings are connected according to the hydraulic circuit diagram of the slip control. Cartesian means parallel or perpendicular to each other and to surfaces and edges of the hydraulic block in the hydraulic block mounted holes. Equipped with the hydraulic components, the hydraulic block forms a hydraulic unit.
Zu einer Verbindung des Hydraulikblocks mit einem Hauptbremszylinder und zur Verbindung von Radbremsen mit dem Hydraulikblock weisen bekannte Hydraulikblöcke Anschlussbohrungen für Bremsleitungen auf. Die Anschlussbohrungen sind typischerweise zylindrische Ansenkungen bzw. Sacklöcher, die beispielsweise Innengewinde für eine Schraubverbindung mit einem Schraubnippel einer Bremsleitung aufweisen oder gewindelos zum Einpressen und Verstemmen eines Einpressnippels einer Bremsleitung vorzugsweise in sog. self-clinch Technik sind. Self-clinch bedeutet, dass sich der Einpressnippel beim Einpressen in die Anschlussbohrung des Hydraulikblocks unter plastischer Umformung von Material des Hydraulikblocks selbst druckdicht in der Anschlussbohrung des Hydraulikblocks verstemmt. For connecting the hydraulic block with a master cylinder and for connecting wheel brakes to the hydraulic block, known hydraulic blocks have connecting bores for brake lines. The connection bores are typically cylindrical countersinks or blind holes, which have, for example, internal threads for a screw connection with a screw nipple of a brake line or are thread-less for pressing in and caulking a press-fit nipple of a brake line, preferably in so-called self-clinching technique. Self-clinch means that the press-fit nipple when pressing into the connection bore of the hydraulic block with plastic deformation of material of the hydraulic block itself caulked in the connection bore of the hydraulic block.
Die Offenlegungsschrift DE 10 2006 059 924 A1 offenbart einen Hydraulikblock für ein Hydraulikaggregat einer Schlupfregelung einer hydraulischen Fahrzeugbremsanlage, bei dem alle Aufnahmen für Magnetventile der Schlupfregelung in einer Deckseite, die auch als Ventilseite bezeichnet werden kann, eines quaderförmigen Hydraulikblocks angeordnet sind. Die Deckseite ist eine der beiden großen Seiten des quaderförmigen Hydraulikblocks, der nicht würfelförmig ist, sondern länger und breiter als dick. Die Deckseite kann quadratisch oder rechteckig sein. Zentral in einer Längsmittelebene und versetzt zu einer Quermittelebene des Hydraulikblocks weist der bekannte Hydraulikblock einen Exzenterraum in einer Grundseite auf. Die Grundseite, die auch als Motorseite bezeichnet werden kann, liegt der Deckseite gegenüber und ist kongruent zu ihr. Der Exzenterraum ist eine zylindrische, durchmessergestufte Ansenkung und ist für eine Unterbringung eines Pumpenexzenters vorgesehen, der zum Antrieb zweier Hydropumpen dient. Der Pumpenexzenter wird von einem Elektromotor als Pumpenmotor angetrieben, der außen an der Motorseite des Hydraulikblocks angebracht wird. The publication DE 10 2006 059 924 A1 discloses a hydraulic block for a hydraulic unit of a slip control of a hydraulic vehicle brake system, in which all recordings for solenoid valves of the slip control in a cover page, which can also be referred to as the valve side, a cuboid hydraulic block are arranged. The top side is one of the two major sides of the block-shaped hydraulic block, which is not cube-shaped, but longer and wider than thick. The top side can be square or rectangular. Centrally in a longitudinal center plane and offset from a transverse center plane of the hydraulic block, the known hydraulic block has an eccentric space in a base side. The base page, which can also be referred to as the engine side, is opposite the deck side and is congruent with it.

Der erfindungsgemäße Hydraulikblock mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist für ein Hydraulikaggregat einer Schlupfregelung einer hydraulischen Fahrzeugbremsanlage vorgesehen. Der Hydraulikblock weist Aufnahmen für Ventile der Schlupfregelung, insbesondere Magnetventile, in einer der beiden einander gegenüberliegenden großen Seiten des quaderförmigen Hydraulikblocks auf, die allgemein bei einem Quader als Grundseite und als Deckseite be- zeichnet werden. Hier wird die große Seite des Hydraulikblocks, die die Aufnahmen für die Ventile der Schlupfregelung aufweist, auch als Ventilseite bezeichnet. Magnetventile der Schlupfregelung sind Einlassventile, Auslassventile, Trennventile und Ansaugventile. Durch die Einlassventile und die Auslassventile sind Radbremsen an die Schlupfregelung angeschlossen. Die Einlassventile und die Auslassventile bilden Radbremsdruckmodulationsventilanordnungen, mit denen sich Radbremsdrücke in den Radbremsen radindividuell regeln lassen. Mit den Trennventilen lässt sich ein Hauptbremszylinder während einer Schlupfregelung hydraulisch von der Fahrzeugbremsanlage trennen und durch die Ansaugventile lassen sich Hydropumpen für einen schnellen Druckaufbau unmittelbar mit dem Hauptbremszylinder oder einem Bremsflüssigkeitsvorratsbehälter ver- binden. Ansaugventile sind nicht in jeder Schlupfregelung vorhanden, Einlassventile, Auslassventile und Trennventile gibt es normalerweise. The hydraulic block according to the invention with the features of the preamble of claim 1 is provided for a hydraulic unit of a slip control of a hydraulic vehicle brake system. The hydraulic block has receptacles for valves of the slip control, in particular solenoid valves, in one of the two opposing large sides of the block-shaped hydraulic block, which are generally referred to in a cuboid as a base side and as a cover page. Here, the large side of the hydraulic block, which has the recordings for the valves of the slip control, also referred to as the valve side. Solenoid valves of the slip control are intake valves, exhaust valves, isolation valves and intake valves. Through the inlet valves and the exhaust valves wheel brakes are connected to the slip control. The intake valves and the exhaust valves form wheel brake pressure modulation valve arrangements with which wheel brake pressures in the wheel brakes can be regulated individually for each wheel. With The separating valves allow a master cylinder to be hydraulically separated from the vehicle brake system during slip control, and hydraulic pumps can be directly connected to the master cylinder or a brake fluid reservoir through the intake valves for rapid pressure build-up. Intake valves are not included in any slip control, intake valves, exhaust valves, and isolation valves usually exist.
In Längsseiten weist der erfindungsgemäße Hydraulikblock Aufnahmen für Hydropumpen der Schlupfregelung auf, die gelegentlich auch als Rückförderpumpen bezeichnet werden und meistens Kolbenpumpen, gelegentlich auch (Innen-) Zahnradpumpen sind. In longitudinal sides of the hydraulic block according to the invention has recordings for hydraulic pumps of the slip control, which are sometimes referred to as return pumps and mostly piston pumps, occasionally also (internal) gear pumps.
Eine Querseite des erfindungsgemäßen Hydraulikblocks ist zur Anbringung eines Elektromotors zum Antrieb von Hydropumpen der Schlupfregelung vorgesehen, die in den Aufnahmen für die Hydropumpen des Hydraulikblocks angeordnet sind. Die Querseite des Hydraulikblocks, die zur Anbringung des Elektromotors zum Antrieb der Hydropumpen vorgesehen ist, wird hier auch als Motorseite bezeichnet. Sie kann kürzer, gleich lang oder länger als die Längsseiten des Hydraulikblocks sein. A transverse side of the hydraulic block according to the invention is provided for mounting an electric motor for driving hydraulic pumps of the slip control, which are arranged in the receptacles for the hydraulic pumps of the hydraulic block. The transverse side of the hydraulic block, which is provided for mounting the electric motor for driving the hydraulic pumps, is also referred to as the engine side.

Gegenstand der Unteransprüche sind vorteilhafte Ausgestaltungen und Weiterbildungen der im Anspruch 1 angegebenen Erfindung. The subject of the dependent claims are advantageous refinements and developments of the invention specified in claim 1.
Die Erfindung ermöglicht eine Anordnung aller Magnetventile der Schlupfrege- lung an einer Seite des Hydraulikblocks, und zwar wie bei bekannten derartigenThe invention makes it possible to arrange all the magnetic valves of the slip control on one side of the hydraulic block, as in known ones
Hydraulikblöcken in drei Reihen mit je vier Magnetventilen. Außerdem ist eine Anordnung von Anschlussbohrungen für hydraulische Radbremsen und einen Hauptbremszylinder an den Seiten und den Stellen des Hydraulikblocks möglich, an denen sie sich auch bei vielen bekannten derartigen Hydraulikblöcken befin- den. Der mit den Bauelementen der Schlupfregelung bestückte Hydraulikblock lässt sich an einer üblichen Stelle in einen Motorraum eines Kraftwagens unterbringen und an die üblichen Bremsleitungen ohne Änderungen anschließen.

The equipped with the components of the slip control hydraulic block can be accommodated at a conventional location in an engine compartment of a motor vehicle and connect to the usual brake lines without changes.
Unter einer Bohrung ist ein Durchgangsloch oder ein Sackloch unabhängig von der Art seiner Herstellung zu verstehen. Eine Bohrung muss also nicht durch Bohren sondern kann beispielsweise durch Fräsen oder in sonstiger Weise hergestellt sein. Under a bore, a through hole or a blind hole is independent of the manner of its production to understand. So a hole does not have to go through Drilling but can be made for example by milling or otherwise.

Der in Figuren 1 und 2 dargestellte, erfindungsgemäße Hydraulikblock 1 ist für ein Hydraulikaggregat einer Schlupfregelung einer im Übrigen nicht dargestellten 20 hydraulischen Fahrzeugbremsanlage vorgesehen. Solche Schlupfregelungen sind beispielsweise Blockierschutz-, Antriebsschlupf- und/oder Fahrdynamikregelungen/elektronische Stabilitätsprogramme, für die die Abkürzungen ABS, ASR, FDR/ESP gebräuchlich sind. Der Hydraulikblock 1 ist ein quaderförmiger Metallblock, der in der hier verwendeten Terminologie breiter und länger als dick ist. ErThe illustrated in Figures 1 and 2, inventive hydraulic block 1 is provided for a hydraulic unit of a slip control of a otherwise not shown 20 hydraulic vehicle brake system. Such slip controls are, for example, anti-lock, traction and / or vehicle dynamics control / electronic stability programs, for which the abbreviations ABS, ASR, FDR / ESP are common.

Für eine hydraulische Fahrzeugbremsanlage mit zwei Bremskreisen und vier Radbremsen - in jedem Bremskreis zwei Radbremsen - weist der Hydraulikblock 1 vier Aufnahmen 3 für Einlassventile, vier Aufnahmen 4 für Auslassventile, zwei Aufnahmen 5 für Trennventile und zwei Aufnahmen 6 für Ansaugventile auf. Es sind die vier Aufnahmen 3 für die Einlassventile in einer ersten Reihe parallel zu einer Querseite 7 des Hydraulikblocks 1 , die vier Aufnahmen 4 für die Auslassventile in einer zweiten Reihe ebenfalls parallel zu der Querseite 7 und die beiden Aufnahmen 5 für die Trennventile außen sowie die beiden Aufnahmen 6 für die Ansaugventile innen in einer dritten Reihe parallel zu der Querseite 7 in der Ventilseite 2 des Hydraulikblocks 1 angebracht. In anderen Seiten außer der Ventilseite 2 weist der Hydraulikblock 1 keine Aufnahmen für Magnetventile der Schlupfregelung auf. Andere Anzahlen und eine andere Anordnung der Aufnahmen 3, 4, 5, 6 für die Magnetventile in der Ventilseite 2 sind möglich. 30 recorded slip control solenoid valves. For a hydraulic vehicle brake system with two brake circuits and four wheel brakes - two wheel brakes in each brake circuit - the hydraulic block 1 has four receptacles 3 for Intake valves, four intake 4 receptacles 4, two intake 5 isolators and two intake manifold intake manifolds 6. There are the four receptacles 3 for the intake valves in a first row parallel to a transverse side 7 of the hydraulic block 1, the four receptacles 4 for the exhaust valves in a second row also parallel to the transverse side 7 and the two receptacles 5 for the separating valves outside and two receptacles 6 for the intake valves inside a third row parallel to the transverse side 7 in the valve side 2 of the hydraulic block 1 is mounted. In other pages except the valve side 2, the hydraulic block 1 has no recordings for solenoid valves of the slip control. Other numbers and a different arrangement of the receptacles 3, 4, 5, 6 for the solenoid valves in the valve side 2 are possible.
Die Aufnahmen 3, 4, 5, 6 für die Magnetventile sind zylindrische, durchmessergestufte Ansenkungen im Hydraulikblock 1 , in die die nicht dargestellten Mag- netventile der Schlupfregelung in sogenannter self-clinch Technik eingepresst werden. Das bedeutet, dass die Magnetventile beim Einpressen Material des Hydraulikblocks 1 plastisch so verformen, dass sie mechanisch gehalten und druckdicht in den Aufnahmen 3, 4, 5, 6 abgedichtet sind. The receptacles 3, 4, 5, 6 for the solenoid valves are cylindrical, diameter-graded countersinks in the hydraulic block 1, in which the not shown Mag- netventile the slip control in so-called self-clinching technique are pressed. This means that the solenoid valves during pressing material of the hydraulic block 1 plastically deform so that they are mechanically held and pressure-tight in the receptacles 3, 4, 5, 6 are sealed.
In der Querseite 7, die der ersten Reihe mit den Aufnahmen 3 für die Einlassventile am nächsten liegt, weist der Hydraulikblock 1 vier Anschlussbohrungen 8 zum Anschluss nicht gezeichneter, hydraulischer Radbremsen der Schlupfregelung auf. Die Anschlussbohrungen 8 für die Radbremsen sind in einer Reihe parallel zur Ventilseite 2 in der Querseite 7 angeordnet. Die Anschlussbohrungen 8 sind zylindrische Ansenkungen mit beispielsweise Innengewinden zu einem Schraubanschluss von Bremsleitungen mit Schraubnippeln oder ohne Innengewinde für einen Anschluss von Bremsleitungen durch Verstemmen. Das Ver- stemmen kann in sog. Self-Clinch Technik mit speziellen Nippeln erfolgen, die Material des Hydraulikblocks 1 beim Einpressen der Nippel in die Anschlussbohrungen 8 so umformen, dass die Nippel mechanisch gehalten und druckfest in den Anschlussbohrungen 8 abgedichtet sind. Die Anschlussbohrungen 8 müssen nicht durch Bohren, sondern können auch in anderer Weise hergestellt, beispielsweise gefräst sein. In Längsseiten 9 weist der Hydraulikblock 1 zwei Aufnahmen 10 für Kolbenpumpen der Schlupfregelung auf. Die Aufnahmen 10 für die Kolbenpumpen sind gleichachsig einander gegenüber im Hydraulikblock 1 angebracht. Die Längsseiten 9 müssen nicht länger als die Querseite 7 sein, bei dem in Figuren 1 und 2 gezeichneten Hydraulikblock 1 sind die Längsseiten 9 kürzer als die Querseiten 7, in Figur 3 sind sie länger. Die Aufnahmen 10 für die Hydropumpen sind zylindrische, durchmessergestufte Löcher, die zum Einbau nicht dargestellter Kolbenpumpen als Hydropumpen der Schlupfregelung der nicht dargestellten hydraulischen Fahrzeugbremsanlage vorgesehen sind. Typischerweise werden solche Kolbenpumpen in die Pumpenbohrunggen eines Hydraulikblocks eingepresst. In the transverse side 7, which is the first row with the receptacles 3 for the intake valves closest, the hydraulic block 1 has four connection holes 8 for connection not drawn, hydraulic wheel brakes of the slip control. The connection bores 8 for the wheel brakes are arranged in a row parallel to the valve side 2 in the transverse side 7. The connection holes 8 are cylindrical countersinks with, for example, internal threads to a screw connection of brake lines with Schraubnippeln or without internal thread for a connection of brake lines by caulking. The staking can be carried out in so-called self-clinching technique with special nipples that transform the material of the hydraulic block 1 when the nipples are pressed into the connection bores 8 in such a way that the nipples are mechanically held and pressure-tightly sealed in the connection bores 8. The connection holes 8 need not be made by drilling, but can also be produced in other ways, for example milled. In longitudinal sides 9, the hydraulic block 1 has two receptacles 10 for piston pumps of the slip control. The receptacles 10 for the piston pumps are coaxially mounted opposite each other in the hydraulic block 1. The longitudinal sides 9 need not be longer than the transverse side 7, in the drawn in Figures 1 and 2 hydraulic block 1, the longitudinal sides 9 are shorter than the transverse sides 7, in Figure 3, they are longer. The receptacles 10 for the hydraulic pumps are cylindrical, diameter-graduated holes, which are provided for the installation of unillustrated piston pumps as hydraulic pumps of the slip control of the hydraulic vehicle brake system, not shown. Typically, such piston pumps are pressed into the Pumpenbohrunggen a hydraulic block.

Die Aufnahmen 10 für die Hydropumpen sind radial zu einer Achse des Elektromotors 1 1 im Hydraulikblock 1 angeordnet, wobei der Elektromotor 11 außen am Hydraulikblock 1 angebracht wird. Gleichachsig zum Elektromotor 11 ist ein Exzenterraum 12 in der Motorseite des Hydraulikblocks 1 angebracht. Der Exzenterraum 12 dient der Unterbringung eines nicht gezeichneten Pumpenexzenters zum Antrieb der Hydropumpen, der mit dem Elektromotor 1 1 antreibbar ist. Die Aufnahmen 10 für die Hydropumpen, die in Figuren 1 und 2 mit Strichlinien angedeutet sind, münden radial in den Exzenterraum 12, der in Figuren 1 und 2 ebenfalls mit Strichlinien angedeutet ist. One of the transverse side 7 with the connecting holes 8 opposite transverse side of the hydraulic block 1, which is referred to here as the engine side and is located in the drawing below the hydraulic block 1, is for mounting an indicated with dashed lines electric motor 1 1 to drive in the receptacles 10 for the hydraulic pumps arranged hydraulic pumps provided. The receptacles 10 for the hydraulic pumps are arranged radially to an axis of the electric motor 1 1 in the hydraulic block 1, wherein the electric motor 11 is externally attached to the hydraulic block 1. Coaxially to the electric motor 11, an eccentric 12 is mounted in the engine side of the hydraulic block 1. The eccentric 12 is used to accommodate a not shown pump eccentric for driving the hydraulic pumps, which is driven with the electric motor 1 1. The receptacles 10 for the hydraulic pumps, which are indicated in dashed lines in Figures 1 and 2, open radially into the eccentric 12, which is also indicated in Figures 1 and 2 with dashed lines.
In einer der Ventilseite 2 gegenüberliegenden zweiten großen Seite 13, die dem Betrachter in Figur 2 zugewandt ist, weist der Hydraulikblock 1 zwei zylindrische Ansenkungen als Aufnahmen 14 für Hydrospeicher auf. Die Aufnahmen 14 für die Hydrospeicher sind ungefähr in einer Mitte zwischen der Querseite 7 und der Motorseite des Hydraulikblocks 1 angeordnet, das heißt ungefähr in Höhe der zweiten und der dritten Reihe mit den Aufnahmen 4, 5, 6 für die Auslassventile, Trennventile und Ansaugventile angeordnet und weisen einen größeren Durchmesser auf als die Aufnahmen 3, 4, 5, 6 für die Magnetventile auf. In der dargestellten und beschriebenen Ausführungsform der Erfindung sind die Aufnahmen 14 für die Hydrospeicher niedrig, die nicht gezeichneten Hydrospeicher werden durch Verstemmen druckdicht am Hydraulikblock 1 befestigt und stehen nach außen vom Hydraulikblock 1 ab. Steht genügend Bauraum im Hydraulikblock 1 zur Verfügung, können die nicht gezeichneten Hydrospeicher auch teilweise oder vollständig versenkt im Hydraulikblock 1 angeordnet werden (nicht dargestellt). In one of the valve side 2 opposite second large side 13, which faces the viewer in Figure 2, the hydraulic block 1 has two cylindrical countersinks as receptacles 14 for hydraulic accumulator. The receptacles 14 for the hydraulic accumulators are arranged approximately in a middle between the transverse side 7 and the engine side of the hydraulic block 1, that is arranged approximately at the level of the second and third row with the receptacles 4, 5, 6 for the exhaust valves, separating valves and intake valves and have a larger diameter than the receptacles 3, 4, 5, 6 for the solenoid valves. In the illustrated and described embodiment of the invention, the receptacles 14 for the hydraulic accumulator low, not shown hydraulic accumulators are pressure-tight fixed by caulking the hydraulic block 1 and stand out from the hydraulic block 1 from. Is there enough space in the hydraulic block 1 available, not shown hydraulic accumulators can also be partially or completely sunk in the hydraulic block 1 are arranged (not shown).

Die Anschlussbohrungen 15 für den Hauptbremszylinder sind gleich ausgeführt wie die Anschlussbohrungen 8 für die Radbremsen. Two-circuit master cylinder in the valve side 2 opposite large side 13 with the receptacles 14 for the hydraulic accumulator. The connection bores 15 for the master brake cylinder are the same as the connection bores 8 for the wheel brakes.
Der Hydraulikblock 1 ist kartesisch, das heißt parallel und rechtwinklig zu seinen Kanten und Seiten 2, 7, 9, 13 und spiegelsymmetrisch zu einer Längsmittelebene verbohrt. Die Längsmittelebene befindet sich in einer Mitte zwischen und verläuft parallel zu den Längsseiten 9. Spiegelsymmetrisch zur Längsmittelebene heißt, die Aufnahmen 3, 4, 5, 6, 10, 14 für die hydraulischen Bauelemente der Schlupfregelung sind spiegelsymmetrisch zur Längsmittelebene im Hydraulikblock 1 angebracht. Die Achse des Exzenterraums 12 und des Elektromotors 11 befindet sich in der Längsmittelebene. Einzelne Abweichungen von der Symmetrie sind nicht ausgeschlossen. The hydraulic block 1 is Cartesian, that is drilled parallel and perpendicular to its edges and sides 2, 7, 9, 13 and mirror-symmetrical to a longitudinal center plane. The longitudinal center plane is located in a middle between and runs parallel to the longitudinal sides 9. Mirror-symmetrical to the longitudinal center plane means receptacles 3, 4, 5, 6, 10, 14 for the hydraulic components of the slip control are mounted mirror-symmetrically to the longitudinal center plane in the hydraulic block 1. The axis of the eccentric 12 and the electric motor 11 is located in the longitudinal center plane. Individual deviations from the symmetry are not excluded.
Bestückt mit den nicht dargestellten Magnetventilen, Hydropumpen und weiteren hydraulischen Bauelementen einer Schlupfregelung einer nicht dargestellten hydraulischen Fahrzeugbremsanlage bildet der Hydraulikblock 1 ein Hydraulikaggregat, das Kernstück eines hydraulischen Teils der Schlupfregelung bildet. Equipped with the non-illustrated solenoid valves, hydraulic pumps and other hydraulic components of a slip control of a hydraulic vehicle brake system, not shown, the hydraulic block 1 forms a hydraulic unit, which forms the core of a hydraulic part of the slip control.
