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.

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.
