wobei das Schließblech mit den vorgenannten Bauteilen als vormontierte Baueinheit an einer Spritzwand eines Kraftfahrzeuges befestigbar ist.wherein the striking plate with the aforementioned components as a pre-assembled unit can be attached to a bulkhead of a motor vehicle.
Ein Betatigungsaggregat der eingangs beschriebenen Ausfuhrungsform ist im großen und ganzen durch die deutsche Offenlegungsschrift 42 33 167 bekannt geworden. Außerdem sei in diesem Zusammenhang auf die DE-OS 42 30 395 Bezug genommen .An actuating unit of the embodiment described at the outset has become known on the whole from German Offenlegungsschrift 42 33 167. In this context, reference is also made to DE-OS 42 30 395.
Bei dem Bremskraftverstarker handelt es sich regelmäßig um einen Unterdruckbremskraftverstarker, dem üblicherweise ein Hauptbremszylinder zur Betätigung der Kraftfahrzeugbremsanlage nachgeschaltet ist. Der Kupplungsgeber arbeitet im allgemeinen hydraulisch und in Verbindung mit einem am Kupplungsgehause angebrachten Kupplungsnehmer zur Betätigung der Kupplung bzw. zum Betrieb der Kupplungsanlage.The brake booster is usually a vacuum brake booster, which is usually a master brake cylinder for actuating the Motor vehicle brake system is connected downstream. The clutch transmitter generally works hydraulically and in connection with a clutch slave attached to the clutch housing for actuating the clutch or for operating the clutch system.
Im Kraftfahrzeugmnern erfolgt eine entsprechende Betätigung mit Hilfe des Bremspedals und/oder Kupplungspedals, welche an einen gemeinsamen Pedalbock angelenkt sein können oder getrennte Pedalbocke aufweisen. Jedenfalls wirkt das Bremspedal m bekannter Art und Weise m der Regel auf eine Betatigungsstange, welche ihrerseits auf eine Druckstange des Unterdruckbremskraftverstarkers arbeitet oder selbst als solche ausgeführt ist. Das Kupplungspedal lost die angeschlossene Kupplung mit Hilfe hydraulisch übertragener Kräfte durch den Kupplungsgeber und den Kupplungsnehmer aus.A corresponding actuation takes place in the motor vehicle men with the aid of the brake pedal and / or clutch pedal, which can be articulated on a common pedal bracket or have separate pedal bracket. In any case, the brake pedal m generally acts in a known manner on an actuating rod, which in turn works on a push rod of the vacuum brake booster or is itself designed as such. The clutch pedal triggers the connected clutch with the aid of hydraulically transmitted forces through the clutch master and the clutch slave.
Beim Stand der Technik wird im allgemeinen so vorgegangen, daß auf dem Schließblech mittels des zumindest einen Pedalbockes das Bremspedal und das Kupplungspedal montiert werden. Außerdem ist eine Anbringung des Gaspedals möglich. Zusatzlich lassen sich Bremskraftverstarker und Kupplungsgeber befestigen. Dies alles erfordert aufwendige Montageschritte, wobei daruberhinaus die einzelnen vorgenannten Bauteile mit ihren separaten Gehäusen zu einem relativ großen Gewicht des solchermaßen vormontierten Schließbleches beitragen. Dies ist insofern von Nachteil, als die vormontierten Schließbleche üblicherweise beim Zusammenbau eines Kraftfahrzeuges m eine Öffnung der Spritzwand eingeschraubt oder in anderer Weise mit dieser fest verbunden werden. Aus dem großen Gewicht resultieren nicht nur besondere Belastungen des Montagepersonals, sondern auch gegebenenfalls Verzogerungen bei dem Einbau, da sich eine Justage regelmäßig schwierig gestaltet. Hier will die Erfindung insgesamt Abhilfe schaffen.In the prior art, the procedure is generally such that the brake pedal and the clutch pedal are mounted on the striking plate by means of the at least one pedal bracket. It is also possible to attach the accelerator pedal. The brake booster and clutch transmitter can also be attached. All of this requires complex assembly steps, and in addition the individual aforementioned components with their separate housings contribute to a relatively large weight of the striking plate which has been preassembled in this way. This is disadvantageous in that the preassembled striking plates usually have an opening when assembling a motor vehicle Bulkhead screwed in or otherwise firmly connected. The large weight not only results in special loads for the assembly personnel, but also, if necessary, delays in the installation, since adjustment is regularly difficult. The invention as a whole aims to remedy this.
Der Erfindung liegt das technische Problem zugrunde, ein Betatigungsaggregat der eingangs beschriebenen Ausfuhrungsform so weiterzubilden, daß bei reduziertem Gewicht eine einfache Montage möglich ist.The invention is based on the technical problem of developing an actuating unit of the embodiment described at the outset in such a way that simple assembly is possible with reduced weight.
Zur Losung dieser Aufgabe schlagt die Erfindung bei einem gattungsgemaßen Betatigungsaggregat für eine Kraftfahrzeugbrems- und/oder -kupplungsanlage vor, daß das Schließblech, zumindest eine Gehausehalfte des Verstarker- gehauses, das Kupplungsgebergehause und der Pedalbock als einteilige Flanschbauemheit ausgebildet sind. Hierdurch lassen sich bereits die Montagekosten deutlich reduzieren, weil beispielsweise eine Anbringung der einen Gehausehalfte (des Verstarkergehauses) am Schließblech ebenso entfallen kann, wie die Befestigung des Kupplungsgebergehauses an dem vorgenannten Bauteil. Gleiches gilt für den Pedalbock. Die vorgenannte Flanschbauemheit bietet darüber hinaus den Vorteil, daß sie bei der Anbringung der erforderlichen Aggregate des Bremskraftverstarkers, des Kupplungsgebers sowie der Lagerbauteile für den Pedalbock als gleichsam Montagehilfe oder Montagelehre dienen kann. Jedenfalls wird durch die einteilige Bauweise bereits eine deutliche Gewichtsreduzierung erreicht, wobei gleichzeitig der Zusammenbau durch die Verringerung der zu verbindenden Teile vereinfacht ist.To solve this problem, the invention proposes in a generic actuating unit for a motor vehicle brake and / or clutch system that the striking plate, at least one half of the amplifier housing, the clutch transmitter housing and the pedal bracket are designed as a one-piece flange unit. As a result, the assembly costs can already be significantly reduced because, for example, attaching one half of the housing (the amplifier housing) to the striking plate can be eliminated, as is fastening the clutch transmitter housing to the aforementioned component. The same applies to the pedal bracket. The aforementioned flange unit also has the advantage that it can serve as an assembly aid or assembly gauge when attaching the required units of the brake booster, the clutch transmitter and the bearing components for the pedal bracket. In any case, a significant weight reduction is already achieved through the one-piece construction, while at the same time the Assembly is simplified by reducing the number of parts to be connected.
Diese Vorteile können noch weiter für den Fall gesteigert werden, daß die Flanschbauemheit als Kunstoffspritzgußteil aus einem Thermoplast, zum Beispiel Polyamid (PA), ausgeführt ist. Die Verwendung eines solchen Werkstoffes ist vorliegend deshalb möglich, weil im Bereich des Schließbleches ausschließlich Temperaturen erreicht werden, welche unterhalb der maximalen Gebrauchstemperaturen solcher Thermoplaste liegen. Diese bewegen sich in der Größenordnung von ca.170/ C bis ca. 200/ C bei Polyamid (PA) .These advantages can be further increased in the event that the flange unit is designed as a plastic injection molded part made of a thermoplastic, for example polyamide (PA). The use of such a material is possible in the present case because in the area of the striking plate only temperatures are reached which are below the maximum service temperatures of such thermoplastics. These range from approx. 170 / C to approx. 200 / C for polyamide (PA).
Jedenfalls ergeben sich weitere Vorteile dahingehend, daß die Fertigung der einteiligen Flanschbauemheit äußerst einfach gestaltet werden kann, weil diese gleichsam einem Zug in einem Spritzgußwerkzeug hergestellt werden kann. Außerdem zeichnen sich derartige Thermoplaste durch hohe Schlagfestigkeit, Saure- und Olbestandigkeit sowie eine gute Schalldampfung aus. Samtliche vorgenannten Eigenschaften sind unabdingbar auf dem beschriebenen Einsatzgebiet und lassen sich auf vorteilhafte Weise mit den verwendeten Werkstoffen darstellen.In any case, there are further advantages in that the manufacture of the one-piece flange unit can be made extremely simple, because it can be produced in a single injection mold, as it were. In addition, such thermoplastics are characterized by high impact resistance, acid and oil resistance and good sound absorption. All of the aforementioned properties are indispensable in the field of use described and can be advantageously represented with the materials used.
Zur Erhöhung der Festigkeit und Gewährleistung einer einfachen Hersteilbarkeit weist die Flanschbauemheit darüber hinaus regelmäßig innen- und außenseitige Verstarkungsrippen auf, die größtenteils in Längsrichtung verlaufen. Zur Montageerleichterung kann das Verstarkergehause zweigeteilt ausgeführt sein und eine mit dem Schließblech e stuckig verbundene Schließblechge- hausehalfte und eine der Spritzwand zugeordnete Spπtzwandgehausehalfte aufweisen. Die Schließblechge- hausehalfte weist im allgemeinen innenseitige bzw. mnenwandseitige Verstarkungsrippen auf, und zwar bevorzugt ihrem Kopfbereich. Um den durch die vorgenannten Verstarkungsrippen erzeugten gleichsam toten Raum zu reduzieren, sieht die Erfindung weiter vor, daß die Schließblechgehausehalfte eine mnenwandseitig, dem Schließblech gegenüberliegend angeordnete, Begrenzungsplatte zur Definition einer Arbeitsdruckkammer zwischen Begrenzungsplatte und der Schließblechgehausehalfte angeordnetem Arbeitskolben besitzt. D.h., die Arbeitsdruckkammer wird durch die innenseitigen Verstarkungsrippen nicht unnötig vergrößert. Hierfür sorgt die vorgenannte Begrenzungsplatte, welche in die Schließblechgehausehalfte eingeklebt oder eingeschweißt sein kann.In order to increase the strength and ensure ease of manufacture, the flange unit also regularly has reinforcing ribs on the inside and outside, which for the most part run in the longitudinal direction. This can make installation easier Be made in two parts and have a striking plate housing half which is connected in one piece to the striking plate e and a half wall housing half which is assigned to the bulkhead. The striking plate housing half generally has reinforcing ribs on the inside or on the inner wall, preferably in the head region thereof. In order to reduce the dead space, as it were, created by the aforementioned reinforcing ribs, the invention further provides that the striking plate housing half has a limiting plate arranged on the inner wall side, opposite the striking plate, for defining a working pressure chamber between the limiting plate and the striking plate housing half. This means that the working pressure chamber is not unnecessarily enlarged by the reinforcing ribs on the inside. This is ensured by the above-mentioned boundary plate, which can be glued or welded into the striking plate half.
Darüber hinaus ist im allgemeinen e n dem Verstarkergehause zugeordneter Zuganker vorgesehen, welcher die bei einer Bremsenbetatigung auftretenden Kräfte abfangt, insbesondere ein durch den Außenluftdruck begünstigtes Zusammenziehen des mit Unterdruck beaufschlagten Verstarkergehauses verhindert. Dieser Zuganker ist nach bevorzugter Ausfuhrungsform der Erfindung die Flanschbauemheit, insbesondere in die Schließblechgehausehalfte, eingespritzt. Dies kann im Zuge αer Herstellung der Flanschbauemheit in der Weise geschehen, daß der Zuganker in das Spritzgußwerkzeug eingelegt und von Kunststoff umspritzt wird. Selbstverständlich sind auch andere Befestigungsmoglichkeiten des Zugankers denkbar.In addition, a tie rod assigned to the amplifier housing is generally provided, which intercepts the forces that occur when the brakes are applied, in particular prevents the amplifier housing, which is subjected to negative pressure, from contracting due to the outside air pressure. According to a preferred embodiment of the invention, this tie rod is injected into the flange unit, in particular into the striker housing half. This can be done in the course of manufacturing the flange unit in such a way that the tie rod inserted into the injection mold and overmolded with plastic. Of course, other fastening options for the tie rod are also conceivable.
Schließlich ist der Hauptbremszylinder mit Druckmittelvor- ratsbehalter regelmäßig an der Spπtzwandgehausehalfte befestigt, so daß im Zuge der Montage des Betatigungs- aggregates lediglich Spritzwandgehausehalfte und Flanschbauemheit vereinigt zu werden brauchen. D.h., die Flanschbauemheit kann mit den auf ihr anzubringenden und zu befestigenden Bauteilen ebenso wie die Spritzwandgehausehalfte vormontiert werden. Im Zuge der Endmontage ist es nur noch erforderlich, die beiden vormontierten Baugruppen zum Betatigungsaggregat zu vereinige .Finally, the master brake cylinder with the pressure medium reservoir is regularly fastened to the half-wall housing half, so that only the half-wall housing half and flange assembly need be combined in the course of the assembly of the actuating unit. In other words, the flange unit can be preassembled with the components to be attached and fastened to it, as can the bulkhead housing half. In the course of the final assembly, it is only necessary to combine the two preassembled modules to form the actuating unit.
Im folgenden wird die Erfindung anhand einer lediglich em Ausfuhrungsbeispiel darstellenden Zeichnung naher erläutert; es zeigen:In the following the invention is explained in more detail with reference to a drawing showing only an exemplary embodiment; show it:

In üen Figuren ist em Betatigungsaggregat für eine nicht naher spezi izierte Kraftfahrzeugbrems- und/oder - kupplungsanlage gezeigt. Dieses Betatigungsaggregat weist em Schließblech 1 auf. Das vorgenannte Schließblech 1 ist zur Aufnahme von einem Bremskraftverstarker mit geteiltem Verstarkergehause 2a, 2b eingerichtet. Außerdem nimmt das Schließblech 1 einen Kupplungsgeber mit Kupplungsgebergehause 3 sowie nach dem Ausfuhrungsbeispiel zwei Pedalbocke 4,5 für em nicht dargestelltes Bremspedal und Kupplungspedal auf. Das Schließblech 1 laßt sich mit den vorgenannten Bauteilen, also Bremskraftverstarker mit Verstarkergehause 2a, 2b, Kupplungsgeber mit Kupplungsgebergehause 3 sowie Pedalbocke 4,5 mit Bremspedal und Kupplungspedal, als vormontierte Baueinheit an einer nur angedeuteten Spritzwand 6 eines Kraftfahrzeuges (als Betatigungsaggregat) befestigen.In the figures, an actuating unit for a motor vehicle brake and / or clutch system that is not specified in more detail is shown. This actuation unit has em striking plate 1. The aforementioned striking plate 1 is designed to accommodate a brake booster with a divided amplifier housing 2a, 2b. In addition, the striking plate 1 receives a clutch master with clutch master housing 3 and, according to the exemplary embodiment, two pedal blocks 4, 5 for the brake pedal and clutch pedal (not shown). The striking plate 1 can be fastened with the above-mentioned components, that is to say a brake booster with an amplifier housing 2a, 2b, a clutch master with a clutch master housing 3 and a pedal bracket 4, 5 with a brake pedal and clutch pedal, as a preassembled structural unit on a dashboard 6 of a motor vehicle (only indicated).
Nach dem Ausfuhrungsbeispiel sind das Schließblech 1, die eine Gehausehalfte 2a des Verstarkergehauses, das Kupplungsgebergehause 3 und die beiden Pedalbocke 4,5 als einteilige Flanschbauemheit 7 ausgebildet. Diese einteilige Flanschbauemheit 7 ist in Figur 1 dargestellt. Sie ist als Kunststoffspritzgußteil aus einem Thermoplast, im Ausfuhrungsbeispiel aus Polyamid ausgeführt. Zur Versteifung weist die Flanschbauemheit 7 innen- und außenseitige Verstarkungsrippen 8a, 8b auf, die größtenteils in Längsrichtung verlaufen. Die Verstarkungsrippen 8b sind mnenwandseitig der Gehausehalfte 2a angeordnet, wahrend die Verstarkungsrippen 8a außenseitig vorgesehen sind. Selbstverständlich kann zusätzlich auch em Gaspedal angebracht werden. Das Verstarkergehause 2a, 2b ist zweiteilig ausgeführt und weist eine mit dem Schließblech 1 emstuckig verbundene Schließblechgehausehalfte 2a und eine der Spritzwand 6 zugeordnete Spritzwandgehausehalfte 2b auf. Durch eine Begrenzungsplatte 9 laßt sich der durch die Rippen 8b erzeugte, gleichsam tote Raum 10, reduzieren. Diese Begrenzungsplatte 9 ist mnenwandseitig der Schließblechgehausehalfte 2a angeordnet, und zwar dem Schließblech 1 gegenüberliegend. Sie dient zur Definition einer Arbeitsdruckkammer 11 zwischen Begrenzungsplatte 9 und in der Schließblechgehausehalfte 2a angeordnetem Arbeitskolben 12. Dieser Arbeitskolben 12 ist lediglich mit einer zugehörigen Membran angedeutet. Jedenfalls wird die Arbeitsdruckkammer 11 im Zuge der Betätigung des Bremskraftverstarkers zunehmend belüftet und sorgt für eine entsprechende Bremsverstarkung, wie dies allgemein bekannt und nicht Gegenstand der vorliegenden Erfindung ist.According to the exemplary embodiment, the striking plate 1, the housing half 2a of the amplifier housing, the clutch master housing 3 and the two pedal blocks 4, 5 are designed as a one-piece flange unit 7. This one-piece flange assembly 7 is shown in FIG. 1. It is designed as a plastic injection molded part made of a thermoplastic, in the exemplary embodiment made of polyamide. For reinforcement, the flange unit 7 has reinforcing ribs 8a, 8b on the inside and outside, which for the most part run in the longitudinal direction. The reinforcing ribs 8b are arranged on the inner wall side of the housing half 2a, while the reinforcing ribs 8a are provided on the outside. Of course, an accelerator pedal can also be attached. The amplifier housing 2a, 2b is made in two parts and has an integral part with the striking plate 1 Strike plate housing half 2a and a bulkhead housing half 2b assigned to the bulkhead 6. The, as it were, dead space 10 generated by the ribs 8b can be reduced by a limiting plate 9. This boundary plate 9 is arranged on the inner wall side of the striking plate housing half 2a, namely opposite the striking plate 1. It serves to define a working pressure chamber 11 between the limiting plate 9 and the working piston 12 arranged in the striker housing half 2a. This working piston 12 is only indicated with an associated membrane. In any case, the working pressure chamber 11 is increasingly ventilated during the actuation of the brake booster and provides a corresponding brake booster, as is generally known and is not the subject of the present invention.
Die vorgenannte Begrenzungsplatte 9 ist die Schließzyl dergehausehalfte 2a eingeklebt oder eingeschweißt. Zusatzlich ist em Zuganker 12 verwirklicht, welcher in die Flanschbauemheit 7, im Ausfuhrungsbeispiel m die Schließgehausehalfte 2a, eingespritzt ist. Ausweislich der Figur 2 ist an der Spritzwandgehausehalfte 2b em Hauptbremszylinder, insbesondere e Tandem- Hauptzylmder 13 mit Druckmittelvorratsbehalter 14 befestigt. Zur Montage des Betatigungsaggregates 7 ist es lediglich erforderlich, die vorgenannte Spritzwandgehausehalfte 2b mit den montierten Bauteilen und die Flanschbauemheit 7 mit den hieran angebrachten Baugruppen zu vereinigen, wie dies in Figur 2 dargestellt ist. Das solchermaßen endmontierte Betatigungsaggregat laßt sich im Anschluß hieran unschwer in einer Öffnung der Spritzwand 6 oder an der Spritzwand 6 befestigen.
