Description

DrucksteuervorrichtungPressure control device

Die Erfindung betrifft eine Drucksteuervorrichtung, insbesondere Kraftfahrzeugbremsdruck-Steuervorrichtung, wie Antiblockier-Steuervorrichtung, Antriebsschlupf-Steuervorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a pressure control device, in particular motor vehicle brake pressure control device, such as an anti-lock control device, traction control device according to the preamble of patent claim 1.

Aus der DE 43 25 412 AI ist bereits eine derartige Drucksteuervorrichtung bekannt geworden, die im einzelnen mit in einem Ventilaufnahmekörper angeordneten Drucksteuerventilen versehen ist, welche die Drucksteuerkanäle innerhalb des Ventilaufnahmekörpers elektromagnetisch zu schließen oder zu öffnen vermögen. Auf dem Magnetantrieb befindet sich zur Betätigung der Drucksteuerventile eine zweiteilige Abdeckungseinheit aufgesetzt, die die aus dem Ventilaufnahmekörper hervorstehenden Teile der Drucksteuerventile überdeckt. Zwischen den beiden Gehäuseteilen der Abdeckungseinheit befindet sich eine die Magnetantriebe aufnehmende, metallische Trägerplatte, die mittels einer Schraubverbindung zwischen den beiden Gehäuseteilen fest und gleichzeitig flüssigkeitsdicht eingespannt ist. Teile einer Steuer- und/oder Regelelektronik befinden sich gleichfalls oberhalb der Trägerplatte und damit innerhalb des vom Ventilaufnahmekörper abgewandten Gehäuseteils der Abdeckungseinheit.Such a pressure control device is already known from DE 43 25 412 AI, which is provided in detail with pressure control valves arranged in a valve receiving body, which are able to electromagnetically close or open the pressure control channels within the valve receiving body. To actuate the pressure control valves, a two-part cover unit is placed on the magnetic drive, which covers the parts of the pressure control valves protruding from the valve body. Between the two housing parts of the cover unit there is a metallic carrier plate which receives the magnetic drives and which is clamped firmly and at the same time in a liquid-tight manner by means of a screw connection between the two housing parts. Parts of a control and / or regulating electronics are also located above the carrier plate and thus within the housing part of the cover unit facing away from the valve receiving body.

Daher ist es die Aufgabe der vorliegenden Erfindung, eine Drucksteuervorrichtung der eingangs genannten Art mit möglichst einfachen, kostengünstigen und funktionssicheren M- itteln möglichst kompakt als auch baulich und funktionell variabel gestalten zu können, wobei die Körperschallübertragung innerhalb der Drucksteuervorrichtung möglichst gering bleiben soll.It is therefore the object of the present invention to be able to design a pressure control device of the type mentioned at the outset as simply as possible, inexpensively and functionally reliable means as compactly as possible and structurally and functionally, wherein the structure-borne noise within the pressure control device should remain as low as possible.

Diese Aufgabe wird erfindungsgemäß für eine Drucksteuervorrichtung der eingangs genannten Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.This object is achieved according to the invention for a pressure control device of the type mentioned at the outset with the characterizing features of patent claim 1.

Weitere Merkmale, Vorteile und Anwendungsmöglichkeiten der Erfindung gehen im nachfolgenden aus den Unteransprüchen und aus der Beschreibung eines Ausführungsbeispiels hervor.Further features, advantages and possible uses of the invention will become apparent in the following from the subclaims and from the description of an exemplary embodiment.

Es zeigt die einzige Figur 1 in vereinfachter Darstellung einen Teilschnitt durch eine Drucksteuervorrichtung, die im wesentlichen aus einem blockförmigen, metallischen Ventilaufnahmekörper 1 besteht, der mehrere parallel nebeneinander angeordnete Drucksteuerventile 5 aufnimmt, die mit ihrem Magnetantrieb an der Oberfläche des Ventilaufnahmekörpers 1 hervorstehen und die erfindungsgemäß mit einem abgestuften, ersten Gehäuseteil 2 der Abdeckungseinheit 3 von einem weiteren, zweiten Gehäuseteil 4 der Abdeckungsseite 3 räumlich getrennt sind. Das im wesentlichen topfförmig ge- staltete zweite Gehäuseteil 4 nimmt am Topfboden ein Wälzlager auf, in dem die Antriebswelle eines Elektromotors 6 geführt ist. Der offene, in Richtung des ersten Gehäuseteils 2 sich erstreckende Abschnitt des zweiten Gehäuseteils 4 weist einen radial umlaufenden Kragen auf, der über eine Abdichtung 13 am ersten Gehäuseteil 2 anliegt. Das die wesentlichen Teile des Elektromotors 6 aufnehmende zweite Gehäuseteil 4 kann sowohl kraft- als auch formschlüssig am ersten Gehäuseteil 2 befestigt sein. Hierzu eignen sich beispielsweise Niet-, Schraub-, Clip- und Klebverbindungen, die im einzelnen bekannt sind und von daher nicht näher zu erläutern sind. Wesentlich für die Erfindung ist hierbei, daß das am Ventilaufnahmekörper 1 angebrachte erste Gehäuseteil 2 aus einem gut formbaren, schalldämpfenden Material besteht, während das entfernt vom zweiten Ventilaufnahmekörper 1 am ersten Gehäuseteil 2 angebrachte zweite Gehäuseteil 4 aus einem festigkeitsmäßig sehr steifen Werkstoff besteht. Im vorliegenden Ausführungsbeispiel ist deshalb das zweite Gehäuseteil 4 aus einem Metall, vorzugsweise Dünnblechteil, hergestellt und das erste Gehäuseteil 2 besteht aus einem Nichtmetall, vorzugsweise elektrisch isolierenden Kunststoff. Dadurch, daß das erste Gehäuseteil 2 auf Höhe des zweiten Gehäuseteils 4 mit mehreren Gehäusestufen 8 versehen ist, ergibt sich einerseits eine optimale Raumausnutzung zur Anordnung des Elektromotors 6 und der Drucksteuerventile 5 in der Abdeckungseinheit 3, andererseits auch eine verbesserte Steifigkeit des ersten Gehäuseteils 2, wodurch sich die Gehäusewandstärke des Kunststoffteils als auch dessen Verrippung auf ein Minimum reduziert. Die abbildungsgemäße Körperkontur des ersten Gehäuseteils 2 läßt sich somit mit den an sich für Kunststofformteile bekannten Herstellverfahren einfach und dennoch sehr präzise herstellen. Die zweckmäßige Verwendung eines aus Dünnblech bestehenden Gehäusetopfes zur Aufnahme der Magnete 12 des Elektromotors 6 bleibt mit all seinen Vorzügen hinsichtlich guter Herstellbarkeit und entsprechend geforderter hoher Steifigkeit unbe- einträchtigt. Die Welle des Elektromotors 6 wird hierbei nicht nur am Topfboden des zweiten Gehäuseteils 4 gelagert, sondern auch gleichzeitig am gegenüberliegenden Wellenabschnitt. Hierzu ist das erste Gehäuseteil 2 mit einem Bund 11 versehen, der somit eine Teilfassung für die Wellenlagerung und damit für die Motorlagerung 9 bildet. Zur Hindurchführung der Welle des Elektromotors 6 durch das erste, mit den Gehäusestufen 8 versehenen Gehäuseteil 2 befindet sich im ersten Gehäuseteil 2 eine an den Wellendurchmesser angepaßte Durchgangsöffnung 7, die mit der beiderseits der Welle angebrachten Motorlagerung 9 fluchtet. Durch die vorgestellte Wellenlagerung des Elektromotors 6 innerhalb des ersten und zweiten Gehäuseteils 2,4 ergibt sich eine eigenständig handhabbare, vormontierte und vorprüfbare Baueinheit, so daß der Elektromotor 6 unabhängig vom Ventilaufnahmekörper 1 in Betrieb genommen werden kann. Da es sich bei dem vorgeschlagenen Elektromotor um die Bauform eines Bürstenläufers handelt, besteht über die im ersten Gehäuseteil 2 vorzugsweise in dessen Stirnwand eingespritzten und in Richtung des Ventilaufnahmekörpers 1 hervorstehenden Stromkontakte 14 die Möglichkeit zum Anschluß einer Gleichstromquelle einer Prüfeinrichtung, bevor überhaupt der Ventilaufnahmekörper 1 montiert ist. In Fig. 1 ist hierzu gut die Lage des Bürstenhalters 15 an der äußeren, zum Elektromotor 6 hin gerichteten Stirnwand des ersten Gehäuseteils 2 zu erkennen, womit das erste Gehäuseteil 2 nicht nur eine Abdeckungsfunktion der Drucksteuerventile 5 und Lagerfunktion des Elektromotors 6 übernimmt, sondern gleichfalls auch die Aufgabe der an sich bekannten Bürstenträgerplatte erfüllt. Die zweiteilige, den Elektromotor 6 aufnehmende Abdeckungseinheit 3 wird entsprechend der Fig. 1 an der die Magnetantriebe der Drucksteuerventile 5 aufweisenden Stirnfläche des Ventilaufnahmekörpers 1 mittels kraft- und/oder formschlüssiger Befestigungsmittel angebracht. Hierbei ragt das eine Wellende mit seinem Exzenter in ein Nadellager, das ein funktionelles Zwischenglied einer im Ventilaufnahmekörper 1 integrierten Pumpe ist. Aus Fig. 1 wird klar ersichtlich, daß durch die erfindungsgemäße Anordnung des aus Kunststoff bestehenden ersten Gehäuseteils 2 zwischen dem metallischen zweiten Gehäuseteil 4 und dem metallischen Ventilaufnahmekörper 1 der Kunststoff als Schalldämpfer wirkt. Damit unterbleibt die an sich bei Metallen hinreichend bekannte schnelle Schallfortpflanzung und Schallverstärkung durch das als Schallsperre wirkende erste Gehäuseteil 2. Ein weiterer erheblicher Vorteil der zweiteiligen Abdeckungseinheit 3 ist darin zu sehen, daß quasi das zweite Gehäuseteil 4 als Einheitsteil mit gleichem Anschlußbild universell für verschiedene Drucksteuervorrichtungen verwendet werden kann. Das erste Gehäuseteil 2 übernimmt in solchen Fällen die Funktion eines Adapterteils, das entsprechend der Ventilbestückung des Ventilaufnahmekörpers 1 relativ leicht als Formspritzteil an die not- wendige Bauraumgestaltung für die Drucksteuerventile 5 angepaßt werden kann. Auch das erste Gehäuseteil 2 läßt sich verhältnismäßig einfach mit einem gleichbleibenden Anschlußbild zur Aufnahme des zweiten Gehäuseteils 4 ausführen, wobei dem ersten Gehäuseteil 2 klar erkennbar eine Motorträgerfunktion zukommt.1 shows a simplified illustration of a partial section through a pressure control device, which essentially consists of a block-shaped, metallic valve receiving body 1, which accommodates a plurality of pressure control valves 5 arranged in parallel next to one another, which project with their magnetic drive on the surface of the valve receiving body 1 and which are in accordance with the invention with a stepped, first housing part 2 of the cover unit 3 are spatially separated from a further, second housing part 4 of the cover side 3. The essentially pot-shaped Designed second housing part 4 receives a roller bearing on the pot bottom, in which the drive shaft of an electric motor 6 is guided. The open section of the second housing part 4 which extends in the direction of the first housing part 2 has a radially circumferential collar which bears against the first housing part 2 via a seal 13. The second housing part 4, which receives the essential parts of the electric motor 6, can be fastened to the first housing part 2 in a non-positive and positive manner. For this purpose, rivet, screw, clip and adhesive connections, for example, are suitable, which are known in detail and therefore cannot be explained in more detail. It is essential for the invention that the first housing part 2 attached to the valve receptacle body 1 consists of a well formable, sound-absorbing material, while the second housing part 4 attached to the first housing part 2 away from the second valve receptacle body 1 consists of a very rigid material. In the present exemplary embodiment, the second housing part 4 is therefore made of a metal, preferably thin sheet metal part, and the first housing part 2 consists of a non-metal, preferably electrically insulating plastic. The fact that the first housing part 2 is provided with a plurality of housing stages 8 at the level of the second housing part 4 results on the one hand in an optimal space utilization for the arrangement of the electric motor 6 and the pressure control valves 5 in the cover unit 3, and on the other hand also an improved rigidity of the first housing part 2, whereby the housing wall thickness of the plastic part and its ribbing are reduced to a minimum. The illustration The body contour of the first housing part 2 can thus be produced simply and yet very precisely using the manufacturing processes known per se for plastic molded parts. The expedient use of a housing pot made of thin sheet metal for receiving the magnets 12 of the electric motor 6 remains unaffected with all its advantages with regard to good manufacturability and the required high rigidity. The shaft of the electric motor 6 is not only supported on the bottom of the pot of the second housing part 4, but also on the opposite shaft section at the same time. For this purpose, the first housing part 2 is provided with a collar 11, which thus forms a partial mount for the shaft bearing and thus for the motor bearing 9. For the passage of the shaft of the electric motor 6 through the first housing part 2 provided with the housing stages 8 there is in the first housing part 2 a passage opening 7 which is adapted to the shaft diameter and which is aligned with the motor mounting 9 mounted on both sides of the shaft. The proposed shaft mounting of the electric motor 6 within the first and second housing parts 2, 4 results in an independently manageable, preassembled and pre-testable structural unit, so that the electric motor 6 can be put into operation independently of the valve receiving body 1. Since the proposed electric motor is in the form of a brush rotor, there is the possibility, via the current contacts 14, which are preferably injected into the end wall of the first housing part and protrude in the direction of the valve receiving body 1, to connect a direct current source to a test device, before the valve receiving body 1 at all is mounted. 1, the position of the brush holder 15 on the outer end wall of the first housing part 2, which is directed towards the electric motor 6, can be clearly seen, with which the first housing part 2 not only assumes a covering function of the pressure control valves 5 and bearing function of the electric motor 6, but also also fulfills the task of the brush holder plate known per se. The two-part cover unit 3 accommodating the electric motor 6 is attached, according to FIG. 1, to the end face of the valve receiving body 1 which has the magnetic drives of the pressure control valves 5 by means of non-positive and / or positive fastening means. In this case, the one shaft end projects with its eccentric into a needle bearing, which is a functional intermediate element of a pump integrated in the valve receiving body 1. From Fig. 1 it is clear that the inventive arrangement of the first plastic housing part 2 between the metallic second housing part 4 and the metallic valve body 1, the plastic acts as a silencer. The rapid propagation and amplification of sound by the first housing part 2, which acts as a sound barrier, and is well known in metals, is thus omitted. Another considerable advantage of the two-part cover unit 3 can be seen in the fact that the second housing part 4, as a unit part with the same connection pattern, is universal for different pressure control devices can be used. In such cases, the first housing part 2 takes on the function of an adapter part which, in accordance with the valve configuration of the valve receiving body 1, is relatively easy as a molded part to the emergency Agile space design for the pressure control valves 5 can be adapted. The first housing part 2 can also be designed relatively easily with a constant connection diagram for receiving the second housing part 4, the first housing part 2 having a motor carrier function that is clearly recognizable.

Ergänzend wird noch darauf verwiesen, daß zur Stromversorgung bzw. Ansteuerung des Elektromotors 6 und der Drucksteuerventile 5 zumindest Teile einer Steuer- und/oder Regelelektronik 16 an der Stirnfläche des Ventilaufnahmekörpers 1 positioniert sind, womit sich eine gute Wärmeableitung ergibt, andererseits jedoch auch die Montage der schematisch als Platte skizzierten Steuer- und/oder Regelelektronik 16 im ersten Gehäuseteil 2 nicht ausgeschlossen ist. In addition, reference is made to the fact that at least parts of control and / or regulating electronics 16 are positioned on the end face of the valve receiving body 1 for the power supply or control of the electric motor 6 and the pressure control valves 5, which results in good heat dissipation, but on the other hand also the assembly the control and / or regulating electronics 16 schematically sketched as a plate in the first housing part 2 is not excluded.
