Description
Technischer Hintergrundtechnical background
Die Erfindung geht aus von einem Hydraulikaggregat für eine elektronisch regelbare Fahrzeugbremsanlage entsprechend der Gattung des Anspruchs 1. In Bremsanlagen moderner Kraftfahrzeuge ermöglichen es derartige Hydraulikaggregate, dass das Fahrzeug im Falle eines Bremsvorgangs bei maximaler Fahrzeugverzögerung lenkbar bleibt, dass im Falle der Regelung des Antriebsschlupfs die Kraft des Fahrzeugantriebs in Vortrieb des Fahrzeugs umsetzbar ist, oder dass im Falle einer Regelung der Fahrdynamik das Fahrzeug in der vom Fahrer gewünschten Spur gehalten werden kann. Hierzu regelt das Hydraulikaggregat in Abhängigkeit der Reibungsverhältnisse zwischen den Rädern des Fahrzeugs und der Fahrbahn den Bremsdruck radindividuell. Die Erfassung dieser Reibverhältnisse erfolgt durch fahrzeugseitige Sensoren, deren Signale in einem mit dem Hydraulikaggregat zusammenwirkenden elektronischen Steuergerät verarbeitet werden.The Invention is based on a hydraulic unit for an electronically controllable Vehicle brake system according to the preamble of claim 1. In Brake systems of modern motor vehicles enable such hydraulic units that the vehicle is steerable in the event of braking at maximum vehicle deceleration remains that in the case of regulation of traction slip the force the vehicle drive can be converted into propulsion of the vehicle, or that in the case of regulation of the driving dynamics, the vehicle in the desired by the driver Track can be kept. The hydraulic power unit regulates in dependence the friction conditions between the wheels of the vehicle and the road surface, the brake pressure for each wheel. The Detection of these frictional relationships is carried out by on-board sensors, the signals of which are in one the hydraulic unit interacting electronic control unit processed become.
Bekannte Hydraulikaggregate umfassen einen metallischen Gehäuseblock, in den Einbauräume für ein Antriebselement, wenigstens für ein Pumpenelement, für Magnetventile und für Anschlüsse zur hydraulischen Kontaktierung dieses Hydraulikaggregats unter anderem mit einem anbaubaren Hochdruckspeicher, dem Hauptbremszylinder und den Radbremsrylindern einer Fahrzeugbremsanlage ausgebildet sind. Im Gehäuseblock sind darüber hinaus Druckmittelkanäie angeordnet, die die verschiedenen Einbauräume miteinander verbinden.Known Hydraulic units include a metallic housing block, in the installation space for a Drive element, at least for a pump element, for Solenoid valves and for Connections to hydraulic contacting of this hydraulic unit among others with a mountable high pressure accumulator, the master brake cylinder and the wheel brake cylinders of a vehicle brake system are formed. In the housing block are about it also pressure medium channels arranged that connect the different installation spaces with each other.
Die Einbauräume, Anschlüsse und Druckmittelkanäle sind in erster Linie aus fertigungstechnischer Sicht am Gehäuseblock platziert. Dabei ist das Augenmerk auf einen möglichst geringen Zerspanungsaufwand bei gleichzeitig möglichst wenigen Aufspannungen des Rohlings des Gehäuseblocks gerichtet. Möglichst rechtwinklig aufeinandertreffende Zerspanungsquerschnitte werden ebenso angestrebt wie besonders kompakte Außenabmessungen des Gehäuseblocks.The Installation spaces, connections and pressure medium channels are primarily on the housing block from a manufacturing perspective placed. The focus is on the lowest possible machining effort at the same time if possible directed a few clamps of the blank of the housing block. preferably machining cross sections that meet at right angles aspired as well as particularly compact external dimensions of the housing block.
Diese Prämissen führen bei bekannten Hydraulikaggregaten dazu, dass ein anbaubarer Hochdruckspeicher lediglich an einer Seite des Gehäuseblocks montierbar ist. Dies schränkt die Einsetzbarkeit des Hydraulikaggregats für verschiedene Fahrzeugtypen ein.This premises to lead in known hydraulic units, that a mountable high-pressure accumulator only on one side of the housing block is mountable. This limits the usability of the hydraulic unit for different vehicle types on.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zu Grunde, bei einem Gehäuseblock eines Hydraulikaggregats eine Anordnung von Einbauräumen und Druckmittelkanälen vorzuschlagen, die bei unveränderten Außenabmessungen und Zerspanungseigenschaften des Gehäuseblocks eine breitere Varianz bezüglich der Anordnung eines anbaubaren Hochdruckspeichers ermöglicht. Diese Aufgabe löst ein Gegenstand mit den Merkmalen des Anspruchs 1.In front Against this background, the invention is based on the object a housing block a hydraulic unit, an arrangement of installation spaces and Pressure fluid channels propose the same at unchanged external dimensions and machining properties of the housing block a wider variance in terms of the arrangement of a mountable high-pressure accumulator enables. This task solves an object with the features of claim 1.
Vorteile der ErfindungAdvantages of invention
Ein Hydraulikaggregat mit einem Gehäuseblock entsprechend den Merkmalen des Anspruchs 1 hat den Vorteil, dass es bei unverändert kompakten Außenabmessungen und nach wie vor guter Zerspanbarkeit die Anordnung eines anbaubaren Hochdruckspeichers in verschiedenen Raumrichtungen erlaubt. Die Erfindung bietet darüber hinaus die Möglichkeit, an Stelle eines einzelnen Speichers zwei getrennte bauraumkleinere Teilspeicher einzusetzen. Die Lage des Speichers und die Länge der Druckmittelkanäle haben entscheidenden Einfluss auf die Funktionseigenschaften und das Betriebsgeräusch der Fahrzeugbremsanlage. In beiden Anordnungen des Hochdruckspeichers sind die Kanallängen und damit das enthaltene Druckmittelvolumen gleich groß. Die Erfindung ermöglicht demnach ohne wesentlichen baulichen Zusatzaufwand eine größere Modellvielfalt, um diese Eigenschaften fahrzeugspezifisch abzustimmen. Die betroffenen Druckmittelkanäle sind besonders kurz ausgebildet und erfordern damit besonders wenig Zerspanungsaufwand. Dies verlängert die Werkzeugstandzeiten. Kurze Kanallängen verringern darüber hinaus das Steuervolumen und erhöhen die Dynamik der Fahrzeugbremsanlage insgesamt.On Hydraulic unit with a housing block according to the features of claim 1 has the advantage that it at unchanged compact external dimensions and still the good machinability the arrangement of an attachable High-pressure accumulator allowed in different spatial directions. The Invention offers about it beyond the possibility instead of a single storage tank, two separate smaller installation spaces Use partial storage. The location of the store and the length of the Pressure fluid channels have a decisive influence on the functional properties and the operating noise of the Vehicle brake system. In both arrangements of the high pressure accumulator are the channel lengths and thus the volume of pressure medium contained is the same size. The invention allows therefore a larger variety of models without significant additional construction effort, to coordinate these properties vehicle-specifically. The affected Pressure fluid channels are particularly short and therefore require very little Chip removal. This extends the tool life. Short channel lengths also reduce the tax volume and increase the dynamics of the vehicle brake system as a whole.
Weitere Vorteile oder vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen oder der nachfolgenden Beschreibung.Further Advantages or advantageous developments of the invention result itself from the subclaims or the description below.
Eine Anordnung zweier Pumpenelemente in einem Winkel, der größer ist als 90°, gemäß Anspruch 2, wirkt sich positiv bezüglich der mechanischen Betriebsgeräusche des Hydraulikaggregats aus. Eine Zusammenführung von Druckmittelkanälen in einem Knoten erlaubt besonders kurze Kanallängen und ist fertigungstechnisch besonders einfach und bauraumgünstig darstellbar, wenn diese Kanäle gemäß Anspruch 4 in einer gemeinsamen Ebene verlaufen. Besonders vorteilhaft ist die Verwendung eines erfindungsgemäßen Hydraulikaggregats in einer Fahrzeugbremsanlage, die gemäß Anspruch 8 eine muskelkraftbetätigte Hilfsbremse und eine fremdkraftbetätigte Betriebsbremse umfasst, da bei derartigen Bremssystemen besonders voluminöse Speicher notwendig sind und deren Platzierung deshalb besondere Bedeutung zukommt.A Arrangement of two pump elements at an angle that is larger than 90 °, according to claim 2, has a positive effect on mechanical operating noise of the hydraulic unit. A combination of pressure medium channels in one Knot allows particularly short channel lengths and is manufacturing technology particularly simple and space-saving representable if these channels according to claim 4 run in a common plane. It is particularly advantageous the use of a hydraulic unit according to the invention in a vehicle brake system, which according to claim 8 a muscle-operated person Auxiliary brake and a power-operated service brake, because with such brake systems, particularly voluminous storage are necessary and their placement is therefore of particular importance due.
