Abstract

An intake device for an internal combustion engine (7) is arranged on the frame of a vehicle, especially a two-wheel vehicle, so that it can oscillate. In order to save both material and space, a frame tube (1) of the vehicle or a tube rigidly fixed to the vehicle frame is designed as intake pipe, which is elastically connected to the other parts (3, 5) of the intake device or to the internal combustion engine (7) itself, for example by way of a bellows-like sleeve (2, 6). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Ansaugvorrichtung für eine Brennkraftmaschine, die am Rahmen eines Fahrzeuges, insbesondere eines Zweirades, schwingungsfähig angeordnet ist.The invention relates to an intake device for an internal combustion engine, which is arranged such that it can vibrate on the frame of a vehicle, in particular a two-wheeler.

Bisher bildet die Ansaugvorrichtung ein mit der eigentlichen Brennkraftmaschine fest verbundenes Aggregat. Daraus ergibt sich ein hoher Materialaufwand und ein vergrößerter Raumbedarf, da die Ansaugvorrichtung die Schwingungsfähigkeit der Brennkraftmaschine dem Fahrzeugrahmen gegenüber nicht behindern bzw. einschränken darf.So far, the intake device has formed a unit that is firmly connected to the actual internal combustion engine. This results in a high cost of materials and an increased space requirement, since the intake device must not impede or restrict the vibrability of the internal combustion engine relative to the vehicle frame.

Der Erfindung liegt somit die Aufgabe zugrunde, diesen Mangel zu beseitigen und eine Ansaugvorrichtung zu schaffen, die eine Material- und Raumeinsparung ermöglicht.The invention is therefore based on the object to remedy this deficiency and to provide a suction device which enables material and space to be saved.

Die Erfindung löst die gestellte Aufgabe dadurch, daß ein Rahmenrohr des Fahrzeuges oder ein am Fahrzeugrahmen starr befestigtes Rohr als Ansaugrohr ausgebildet wird und mit den übrigen Teilen der Ansaugvorrichtung bzw. der Brennkraftmaschine selbst elastisch flexibel, z. B. über eine balgartige Muffe, verbunden ist.The invention solves this problem in that a frame tube of the vehicle or a tube rigidly attached to the vehicle frame is designed as an intake pipe and with the remaining parts of the intake device or the internal combustion engine itself elastically flexible, for. B. is connected via a bellows-like sleeve.

Es bildet also ein Rahmenrohr bereits einen Teil des Ansauggeräuschdämpfers, wodurch ein ohnehin vorhandener Bauteil des Rahmens doppelt benutzt wird und sich die gewünschte Materialeinsparung erzielen läßt. Es ergibt sich aber auch eine Verringerung des Raumbedarfs der Ansaugvorrichtung, da die sonst durch die Relativbewegung der Brennkraftmaschine erforderliche Bewegungsfreiheit des Ansaugrohres nicht mehr in Betracht gezogen werden muß. Dennoch aber ist die Schwingungsfähigkeit der Brennkraftmaschine und gegebenenfalls weiterer Teile der Ansaugvorrichtung gewährleistet, da das als Ansaugrohr dienende Rahmenrohr bzw. das zusätzliche am Rahmen befestigte unbewegliche Rohr in elastisch flexibler Verbindung mit der Brennkraftmaschine bzw. den übrigen Aggregatteilen steht. Die erfindungsgemäße Ansaugvorrichtung ist nicht nur für die Brennkraftmaschine von Zweiradfahrzeugen brauchbar, sondern kann auch bei Fahrzeugkonstruktionen ähnlicher Grundausbildung, z. B. bei Handmähmaschinen od. dgl., angewendet werden.A frame tube therefore already forms part of the intake silencer, as a result of which an already existing component of the frame is used twice and the desired material savings can be achieved. However, there is also a reduction in the space requirement of the intake device, since the freedom of movement of the intake pipe, which is otherwise required by the relative movement of the internal combustion engine, no longer has to be taken into account. However, the ability of the internal combustion engine and possibly other parts of the intake device to vibrate is ensured, since the frame tube serving as the intake tube or the additional immovable tube attached to the frame is in elastically flexible connection with the internal combustion engine or the other unit parts. The suction device according to the invention is not only useful for the internal combustion engine of two-wheeled vehicles, but can also be used in vehicle constructions of a similar basic design, e.g. B. od handheld mowers. Like. Be applied.

Handelt es sich um ein Zweirad mit Triebsatzschwinge, so ist bisher das Luftfilter fix auf dieser Schwinge befestigt, was die Nachteile mit sich bringt, daß das Luftfilter die ungefederten Massen erhöht, an einem geräuschmäßig verhältnismäßig ungünstigen Ort angebracht werden muß und Freiraum für das Einfedern der Triebsatzschwinge erfordert.If it is a two-wheeler with a power unit swing arm, the air filter has so far been firmly attached to this swing arm, which has the disadvantages that the air filter increases the unsprung masses, must be attached in a relatively noisy place and free space for the compression of the Power train swing arm required.

Erfindungsgemäß werden auch diese Mängel beseitigt, indem das Luftfilter am Fahrzeugrahmen befestigt und mit dem nachfolgenden Teil der Ansaugvorrichtung, insbesondere dem Vergaser, elastisch flexibel verbunden ist. Dadurch ist es möglich, den Raum um das Luftfilter für andere Aggregate auszunützen, da auf die Bewegungsfreiheit keine Rücksicht genommen werden muß. Selbstverständlich werden auch die ungefederten Massen verringert und es ist möglich, das Luftfilter an einen geräuschmäßig günstigeren Ort anzubringen.According to the invention, these deficiencies are also eliminated by attaching the air filter to the vehicle frame and flexibly and flexibly connecting it to the following part of the intake device, in particular the carburetor. This makes it possible to use the space around the air filter for other units, since freedom of movement does not have to be taken into account. Of course, the unsprung masses are also reduced and it is possible to mount the air filter in a place with less noise.

Die Zeichnung zeigt als Ausführungsbeispiel die wesentlichen Teile der erfindungsgemäßen Ansaugvorrichtung mit der Brennkraftmaschine im Teilschnitt.The drawing shows an exemplary embodiment of the essential parts of the intake device according to the invention with the internal combustion engine in partial section.

Ein Rahmenrohr 1 des Fahrzeuges ist über eine balgartige Muffe 2 mit dem Luftfilter 3 elastisch nachgiebig verbunden und bildet so einen Teil des Ansauggeräuschdämpfers. Vom Luftfilter bzw. vom Ansauggeräuschdämpfer 3 führt ein Rohr 4 zum Vergaser 5, wobei das Rohr 4 wieder über elastisch flexible Muffen 6 mit den beiden Teilen 3 und 5 verbunden ist. Die Brennkraftmaschine 7 ist im nicht dargestellten Fahrzeugrahmen schwingungsfähig gelagert und weist einen Zylinder 8 auf, an dem das Abgasrohr 9 angeschlossen ist.A frame tube 1 of the vehicle is connected to the air filter 3 in a resilient manner via a bellows-like sleeve 2 and thus forms part of the intake silencer. A pipe 4 leads from the air filter or the intake silencer 3 to the carburetor 5, the pipe 4 being connected to the two parts 3 and 5 again via elastically flexible sleeves 6. The internal combustion engine 7 is mounted such that it can vibrate in the vehicle frame (not shown) and has a cylinder 8 to which the exhaust pipe 9 is connected.
