Es ist Aufgabe der Erfindung eine Vorrichtung zur Prüfung von Luftgeräuschen eines Kraftfahrzeugs zu schaffen, die sich durch einfache Handhabung und gute Wirksamkeit auszeichnet. Dabei sollte aber auch die Vorrichtung so gestaltet sein, dass sie im Rahmen von Qualitätsprüfungen des Personenkraftwagens leicht einsetzbar ist.It The object of the invention is a device for testing aerosound to create a motor vehicle, characterized by ease of use and good effectiveness. But it should also the device be designed so that they are part of quality inspections of the passenger car easy to use.
Nach der Erfindung wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.To The invention achieves this object by the features of the patent claim 1 solved. Further, the invention ausgestaltende features are included in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass qualitätsfördernde Prüfungen von Luftgeräuschen eines Personenkraftwagens lokal auf dem Prüfstand und nicht auf öffentlichen Strassen oder Prüfgeländestrassen durchgeführt werden können. Dabei ist die Blasdüseneinrichtung an einer Transporteinrichtung angebracht, so dass manuelle Bedienungsvorgänge der besagten Blasdüseneinrichtung durch entsprechendes Personal weitgehend entfallen und das Personal sich überwiegend auf die subjektive und/oder manuelle Feststellung der Luftgeräusche konzentrieren kann. Eine vorteilhafte Ausbildung der Blasdüseneinrichtung wird erreicht, wenn letztere mehrere Blasdüsen umfasst, die auf das Dach und Seitenwände des Aufbaus des Personenkraftwagens gerichtet sind. Dies wird auch noch dadurch unterstützt, dass zumindest die auf das Dach des Aufbaus gerichtete Blasdüse relativ zum Personenkraftwagen verstellbar ausgebildet ist. Durch die in Längsrichtung des Personenkraftwagens bewegliche Ausbildung der Transporteinrichtung lassen sich zum einen gezielte Messungen der Luftgeräusche und auch definierte Prüfprogramme hierfür realisieren. Eine konstruktiv übersichtliche Lösung ist auch dadurch geschaffen, dass die Blasdüsen der Blasdüseneinrichtung über ein Leitungssystem im den Personenkraftwagen aufnehmenden Prüfstand an wenigstens ein Gebläse angeschlossen sind. Darüber hinaus ist der Aufbau des Traggestells der Transporteinrichtung einfach, und es dient vorbildlich zur Befestigung der Blasdüsen und von Leitungen des Leitungssystems. Schließlich kann der Prüfstand in einem Raum untergebracht sein, der zur Einfahrt des Personenkraftwagens geeignet ist und gegenüber Geräuschquellen abschirmbar ist, um die zu messenden Luftgeräusche weitgehend störungsfrei erfassen zu können.The with the invention mainly The benefits achieved can be seen in the fact that quality-enhancing tests of aerosound a passenger car locally on the test bench and not on public Roads or proving ground roads carried out can be. In this case, the blowing nozzle device attached to a transport device, so that manual operations of the said blowing nozzle device largely eliminated by appropriate staff and the staff predominantly focus on the subjective and / or manual detection of airborne noise can. An advantageous embodiment of the blowing nozzle device is achieved if the latter several tuyeres Includes, on the roof and side walls of the construction of the passenger car are directed. This is also supported by the fact that at least the blast nozzle directed towards the roof of the structure relative is designed to be adjustable to passenger cars. By the in longitudinal direction the passenger car movable training of the transport device On the one hand, targeted measurements of airborne noise and also defined test programs therefor realize. A structurally clear solution is also created by the fact that the nozzles of the blowing nozzle device via a conduit system connected in the passenger car test bench to at least one fan are. About that In addition, the structure of the support frame of the transport device simple, and it serves as an example for attaching the tuyeres and Lines of the pipe system. Finally, the test bench in be housed in a room leading to the entrance of the passenger car is suitable and opposite Sound sources shieldable is to the air noise to be measured largely trouble-free to be able to capture.
In der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher beschrieben ist.In The drawing is an embodiment of the invention, which is described in more detail below.
