Aus der US 4790235 A ist ist eine Befestigungsanordnung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 bekannt. Bei dieser bekannten Anordnung ist ferner die Mutter vorläufig auf den Gewindebolzen aufgeschraubt, welcher eine Gehäuseöffnung durchgreift. Zur Montage des Bremskraftverstärkers an einer Spritzwand ist es erforderlich, den Gewindebolzen zusammen mit der vorläufig aufgeschraubten Mutter in einer bestimmten Position durch eine vergrößerte Öffnung in der Spritzwand axial hindurchzustecken, sodann eine Verdrehung des Bremskraftverstärkers derart vorzunehmen, daß ein schlankerer Öffnungsteil im Bereich der Mutter vorliegt, um schließlich durch das Festdrehen der Mutter eine dauerhafte Befestigung zu erzielen. Um ein selbsttätiges Lösen des Bremskraftverstärkers zu vermeiden, ist die Spritzwand schließlich mit einem Vorsprung versehen, welcher einen Rückdrehvorgang unterbindet. Die Herstellung der Bauteile, insbesondere der Spritzwand mit der Öffnung und dem Vorsprung, ist aufwendig. Ferner weist die Montage Vebesserungspotential auf, weil zeitlich nach einem (axialen) Durchsteckvorgang noch eine koordinierte Verdrehbewegung des Bremskraftverstärkers und schließlich das Festdrehen der Schrauben ausgeführt werden muß, wobei auch dafür Sorge getragen werden muß, daß sich der Gewindebolzen unter dem Drehmoment nicht relativ zu dem Gehäuse verdreht.From US 4790235 A is a mounting arrangement the features of the preamble of claim 1 known. In this known arrangement, the mother is also provisional screwed onto the threaded bolt, which one Reaches through the housing opening. To assemble the Brake booster on a bulkhead it is necessary the threaded bolt together with the provisionally screwed one Nut in a certain position by an enlarged Insert the opening in the bulkhead axially, then one Rotate the brake booster in such a way that there is a slimmer opening part in the area of the nut, to finally make a permanent one by tightening the nut To achieve attachment. To solve the problem automatically Avoiding the brake booster is the bulkhead finally with one Provide projection, which prevents a reverse rotation. The manufacture of the components, especially the bulkhead the opening and the projection is complex. Furthermore, the Montage improvement potential because after a time (axial) push-through process still a coordinated Twisting movement of the brake booster and finally that Tightening the screws must be done, too care must be taken that the threaded bolt not twisted relative to the housing under the torque.
Zur Vermeidung von koordinierten Durchsteck- und Verdrehbewegungen bei Rastvorrichtungen für die Befestigung von Bremskraftverstärkern ist aus der DE 38 04 850 A1 ein mit jeweils einer Radialnut versehener Befestigungszapfen bekannt. Ferner ist die Spritzwand mit Zentrierhülsen und mit separaten Verriegelungselementen versehen, welche im Rahmen der Montage in Einriff in die Nut der Befestigungszapfen bringbar sind. Eine konische Spitze der Befestigungszapfen dient dabei dem Aufspreizen der Verriegelungselemente. Die Gestaltung der Verriegelungselemente erfordert einen hohen Bauaufwand, und eine derartige Rastbefestigung ist für Austauschzwecke nicht lösbar.To avoid coordinated push-through and Twisting movements of locking devices for fastening of brake boosters is from DE 38 04 850 A1 with a radial groove provided mounting pin known. Furthermore, the bulkhead with centering sleeves and with separate locking elements provided, which in the frame the assembly engages in the groove of the fastening pins are feasible. A conical tip of the mounting pin serves to spread the locking elements. The Design of the locking elements requires a high level Construction effort, and such a snap fastening is for Exchange purposes cannot be solved.
Es ist daher eine Aufgabe der vorliegenden Erfindung, eine Anordnung zum Anbringen eines Bremskraftverstärkers der eingangs genannten Gattung dahingehend zu verbessern, daß das Verstärkergehäuse mit einfachen Mitteln und im Rahmen eines einfachen Montage(bewegungs-)vorgangs an der Spritzwand vorfixierbar 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 with simple means and in the context of a simple assembly (movement) process on the bulkhead is pre-fixable.
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 verhakbar 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, the edge of which can be hooked onto the bulkhead is.
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.

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 3, 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, the pins 3 , especially their conical sections 5, yield elastically when inserting the thread and thus get caught or 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 .
