Abstract

The brake servo housing is fitted with mounting bolts (3) which are offered into pre-drilled mounting holes (4) in the bulkhead (2). The bolts have ratchet ridges (5) which provide a press fit into the bulkhead prior to fitting the securing nuts. The edges of the bulkhead holes are slotted radially to enhance the elasticity of the grip. The brake pedal mounting is similarly fitted to the bulkhead prior to fitting the securing nuts.

Description

Die vorliegende Erfindung betrifft eine Anordnung zum An­ bringen eines Bremskraftverstärkers an einer Spritzwand eines Kraftfahrzeuges, wobei das Verstärkergehäuse mit Gewindebolzen versehen ist, die von in der Spritzwand vorgesehenen Öffnungen aufgenommen werden und die mit Muttern zusammenwirken, deren Festziehen die Befestigung des Bremskraftverstärkers an der Spritzwand ermöglicht.The present invention relates to an arrangement for bring a brake booster on a bulkhead one Motor vehicle, the amplifier housing with threaded bolts is provided, the openings provided in the bulkhead are recorded and which work together with nuts, their Tighten the brake booster attachment to the Bulkhead allows.

Bei der Montage bekannter Bremskraftverstärker dieser Art werden die Gewindebolzen vom Motorraum des Kraftfahrzeuges aus durch die in der Spritzwand vorgesehenen Öffnungen hindurchge­ steckt und auf der anderen Seite der Spritzwand bzw. im Fahr­ gastraum, mit Muttern versehen. Sowohl bei der Montage des Bremskraftverstärkers selbst als auch bei der Montage eines mindestens das Bremspedal tragenden Pedalbockes muß der Brems­ kraftverstärker bis zum endgültigen Festschrauben durch Werker oder Montagebetriebsmittel festgehalten werden.When installing known brake boosters of this type the threaded bolts from the engine compartment of the motor vehicle through the openings provided in the bulkhead stuck and on the other side of the bulkhead or while driving guest room, provided with nuts. Both when assembling the Brake booster itself as well as when installing a at least the brake pedal-carrying pedal bracket must be the brake power amplifier until final tightening by the worker or assembly equipment.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Anordnung zum Anbringen eines Bremskraftverstärkers der eingangs genannten Gattung dahingehend zu verbessern, daß das Verstärkergehäuse durch einen Einsteckvorgang an der Spritz­ wand vorfixiert ist, so daß das vorhin erwähnte Festhalten nicht notwendig ist.It is therefore an object of the present invention to Arrangement for attaching a brake booster to improve the genus mentioned in that the Amplifier housing by inserting the sprayer wall is pre-fixed, so that the aforementioned holding is not necessary.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Spritzwand im Bereich der Öffnungen elastisch verformbar ausgebildet ist und daß die Gewindebolzen einen kegelförmigen Abschnitt aufweisen, dessen Rand mit der Spritzwand in Eingriff bringbar ist. This object is achieved in that the Bulkhead elastically deformable in the area of the openings is formed and that the threaded bolt is a conical Have section whose edge with the bulkhead in Intervention can be brought.  

Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind in den Unteransprüchen 2 bis 5 aufgeführt.Advantageous further developments of the subject matter of the invention are listed in subclaims 2 to 5.

Die Erfindung wird in der nachfolgenden Beschreibung eines in der beiliegenden Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigt:The invention is described in the following description of a the accompanying drawing embodiment shown explained in more detail. The drawing shows:

Fig. 1 einen ersten Schritt bei der Montage eines erfindungsgemäßen Bremskraftverstärkers; Figure 1 shows a first step in the assembly of a brake booster according to the invention.

Fig. 2 den Bereich einer in der Spritzwand vorgesehenen Öffnung; Fig. 2 the area of an opening provided in the bulkhead opening;

Fig. 3 die Anordnung nach Fig. 1 in einem an der Spritzwand vorfixierten Zustand; und Fig. 3 shows the arrangement of Figure 1 in a pre-fixed to the bulkhead state. and

Fig. 4 die Anordnung nach Fig. 3 nach der Endmontage einschließlich des Pedalbockes. Fig. 4 shows the arrangement of FIG. 3 after the final assembly including the pedal bracket.

Das in Fig. 1 lediglich schematisch angedeutete Verstärker­ gehäuse 1 eines pneumatischen Bremskraftverstärkers, vorzugs­ weise eines Unterdruckbremskraftverstärkers weist mindestens zwei Gewindebolzen 3 auf, die von in einer Spritzwand 2 eines Kraftfahrzeuges ausgebildeten Öffnungen 4 aufgenommen werden und die einen kegelförmigen Abschnitt 5 aufweisen. Wie insbes­ ondere Fig. 2 zu entnehmen ist, sind im Bereich der Öffnungen 4 radiale Schlitze bzw. Aussparungen 6 vorgesehen, so daß Segmente 11 gebildet werden, die beim Einführen der Gewinde­ bolzen 31 insbesondere deren kegelförmiger Abschnitte 5 elastisch nachgeben und somit ein Verhaken bzw. ein selbst­ tätiges Halten der kegelförmigen Abschnitte 5 in den Öffnungen 4 ermöglichen (Fig. 3). Anschließend werden auf die Gewinde­ bolzen 3 Distanzhülsen 7 aufgeschoben, an denen sich ein in Fig. 4 schematisch dargestellter Pedalbock 8 abstützt. Danach wird die Baugruppe Verstärkergehäuse 1 - Pedalbock 8 unter Zwischenschaltung einer Unterlegscheibe 9 an der Spritzwand 2 endgültig festgeschraubt. Dabei ist es sinnvoll, wenn in dem Raum zwischen der Spritzwand 2 und dem Pedalbock 8 eine Dämmungsschicht 12 vorgesehen ist.The only schematically indicated in Fig. 1 amplifier housing 1 of a pneumatic brake booster, preferably as a vacuum brake booster has at least two threaded bolts 3 which are received by openings 4 formed in a bulkhead 2 of a motor vehicle and which have a conical section 5 . As can be seen in particular on FIG. 2, 4 radial slots or recesses 6 are provided in the area of the openings, so that segments 11 are formed which, when the threaded bolts 31 are inserted, yield in particular their conical sections 5 and thus become caught or caught enable the conical sections 5 to be held automatically in the openings 4 ( FIG. 3). Subsequently, spacer sleeves 7 are pushed onto the threaded bolts 3 , on which a pedal bracket 8, shown schematically in FIG. 4, is supported. Then the assembly amplifier housing 1 - pedal bracket 8 is finally screwed to the bulkhead 2 with the interposition of a washer 9 . It makes sense if an insulation layer 12 is provided in the space between the bulkhead 2 and the pedal bracket 8 .
