Schalldämpfer für Kraftfahrzeuge, insbesondere MotorrollerSilencers for motor vehicles, in particular motor scooters

Die Erfindung betrifft eine Vorrichtung zur Schalldämpfung der Abgasanlage der Verbrennungsmotoren von Kraftfahrzeugen, insbesondere von Motorrollern.The invention relates to a device for soundproofing the exhaust system of the internal combustion engines of motor vehicles, especially from scooters.

Ein derartiger Schalldämpfer stellt insbesondere für Krafträder ein Bauelement mit relativ großem Raumbedarf dar und legt demzufolge dem Fahrzeugkonstrukteur in mancher Hinsicht Beschränkungen in der Gestaltungsfreiheit auf.Such a muffler is a component that requires a relatively large amount of space, in particular for motorcycles, and therefore lays down In some respects, restrictions on the freedom of design are imposed on the vehicle designer.

Die Erfindung schlägt daher eine aus zwei nebeneinander liegenden, vorzugsweise zylindrischen Topfen bestehende Schalldämpfereinheit vor, die über die sonst im Innern des Schalldämpfers angeordnete Reflexionsrohre (Abstimmungsrohre) schalleitend verbunden sind, welche die Töpfe zugleich zumindest einseitig zu einer Montageeinheit zusammenfügen. Zum weiteren Zusammenhalt der Baueinheit dient vorzugsweise ein Verbindungsblech, das auch zur Befestigung der Baueinheit am Fahrgestell dienen kann. Erfolgt diese Verbindung über ein elastisches Glied, so kann zur weiteren Halterung des Schalldämpfers am Fahrzeug ein starr mit dem Motor und dem einen der Töpfe verbundenes Abgasrohr dienan.The invention therefore proposes one of two adjacent, preferably cylindrical pot before existing muffler unit, which is otherwise arranged in the interior of the muffler Reflection tubes (tuning tubes) connected in a sound-conducting manner are, which at the same time join the pots together at least on one side to form an assembly unit. For further cohesion the structural unit is preferably a connecting plate which can also be used to attach the structural unit to the chassis. If this connection is made via an elastic member, a rigid element can be used to further mount the silencer on the vehicle the engine and the exhaust pipe connected to one of the pots are used.

Die Vorteile der Erfindung sollen nachfolgend anhand eines Ausführungsbeispiels dargelegt werden.The advantages of the invention are described below with the aid of an exemplary embodiment be set out.

Die Fig. 1 zeigt eine für Motorroller vorgesehene Auspuffanlage mit"drei Kammern nach der Erfindung in der Seitenansicht, die Fig. 2 einen Schnitt in der Draufsicht und die
Fig.3 einen Querschnitt. Zwei zylindrische Töpfe 1, 2 sind
durch ein Verbindungsblech 3 miteinander zusammengehalten, das über einen Gummipuffer 4 mit dem Fahrgestellteil 5 verbunden ist.1 shows an exhaust system intended for scooters with "three chambers according to the invention in a side view, FIG. 2 shows a section in plan view and FIG
3 shows a cross section. Two cylindrical pots 1, 2 are
held together by a connecting plate 3 which is connected to the chassis part 5 via a rubber buffer 4.

Vom nicht dargestellten Motor führt ein gewundenes Abgasrohr 6- in den Topf 1 und ist in der stirnseitigen Wand 7 dieses Topfes sowie in einer durchbrochenen Zwischenwand 8 verankert. Das an den Motor starr angeschlossene Rohr 6 dient somit zugleich zur Halterung der Schalldämpfereinheit. Zum Zusammenhalt
der beiden Töpfe tragen noch die beiden Resonatorrohre 9, 10 bei, die in den Wandungen der Töpfe 1 und 2 verschweißt sind. Sie können zusätzlich noch mit dem Rohr 6 sowie den beiden Auspuffrohren 11, 12 verbunden werden.From the motor, not shown, a winding exhaust pipe 6- leads into the pot 1 and is anchored in the front wall 7 of this pot and in a perforated partition 8. The pipe 6 rigidly connected to the engine thus also serves to hold the muffler unit. To cohesion
The two resonator tubes 9, 10, which are welded in the walls of the pots 1 and 2, also contribute to the two pots. They can also be connected to the pipe 6 and the two exhaust pipes 11, 12.

Zylindrische Töpfe lassen sich mit guter mechanischer Festigkeit durch einen geringen Fertigungsaufwand herstellen und
haben günstige Schalldämpfungseigenschaften. Die Resonatorrohre 9, 10 können so gelegt werden, daß die für sie erforderlichen Bohrungen in den beiden Topfen an gleichen Stellen liegen. Die Fertigungsstufen für beide Töpfe sind somit zum größten
Teil dieselben. Ferner kann der Abstand der beiden Töpfe ohne Beeinträchtigung der Schalldämpfungseigenschaften in gewissen Grenzen den Einbauerfordernissen angemessen werden. Sollte diese Möglichkeit zur Einpassung der Schalldämpfereinheit in
den zur Verfügung stehenden Einbauraum wegen der durch Fahrzeugteile, z. B. Rahmenrohre, Fahrzeugständer usw., versperrten Unterseite des Motorrollers noch nicht ausreichen, so können die Töpfe auch gegeneinander in Längsrichtung verscho-Cylindrical pots can be manufactured with good mechanical strength and with little manufacturing effort
have favorable soundproofing properties. The resonator tubes 9, 10 can be placed so that the holes required for them in the two pots are in the same places. The production stages for both pots are thus the largest
Part the same. Furthermore, the distance between the two pots can be adapted to the installation requirements within certain limits without impairing the soundproofing properties. Should this option for fitting the silencer unit in
the available installation space because of the vehicle parts such. B. frame tubes, vehicle stands, etc., blocked underside of the scooter are not sufficient, so the pots can also be offset against each other in the longitudinal direction.

Die Anordnung nach der Erfindung ermöglicht es, insbesondere eine maximale Bodenfreiheit für das Fahrzeug zu erzielen.ben or twisted, but then from the outset the bores for the resonator tubes 9, 10 are attached differently Need to become. The arrangement according to the invention makes it possible, in particular, maximum ground clearance for the vehicle to achieve.
