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 capable of oscillating on the frame of a vehicle, in particular a two-wheeler.
  • Bisher bildet die Ansaugvorrichtung ein mit der eigentlichen Brennkraftmaschine fest verbundenes Aggregat. So far, the suction device forms an integral with the actual internal combustion engine unit. 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. This results in a high cost of materials and an increased space requirement, since the suction device is allowed to the vehicle frame with respect to not impede or restrict the oscillation capability of the internal combustion engine.
  • 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 thus based on the object of remedying the deficiency and to create a suction that enables material and space saving.
  • 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. The invention solves the problem by providing a frame tube of the vehicle or a rigidly fixed to the vehicle frame tube is formed as a suction pipe and resiliently flexible with the other parts of the suction device and the internal combustion engine itself, such. B. über eine balgartige Muffe, verbunden ist. 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. already so it forms a frame tube part of the intake silencer, making an already existing part of the frame is used twice and makes the desired material savings achieved. 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. It also follows a reduction in the space requirements of the intake because otherwise required by the relative movement of the engine freedom of movement of the suction pipe must no longer be considered. 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. Nevertheless, however, the oscillation capability of the internal combustion engine and optionally other parts of the suction device is assured, since serving as a suction pipe frame tube or the additional the frame fastened stationary pipe in elastically flexible connection to the internal combustion engine or the other aggregate parts is. Die erfindungsgemäße Ansaugvorrichtung ist nicht nur für die Brennkraftmaschine von Zweiradfahrzeugen brauchbar, sondern kann auch bei Fahrzeugkonstruktionen ähnlicher Grundausbildung, z. The suction device according to the invention is useful not only for the internal combustion engine of two-wheeled vehicles, but can also in vehicle designs like basic training for. B. bei Handmähmaschinen od. dgl., angewendet werden. B. OD at Handmähmaschinen. The like., To 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 Motor unit swinging arm, the air filter is previously fixedly attached to this swing arm, which entails the disadvantages that the air filter increases the unsprung mass, must be attached to a noise standard relatively unfavorable location and clearance for the deflection of the requires Unit swing.
  • 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. According to the invention these drawbacks are eliminated by an air cleaner attached to the vehicle frame and is elastically connected with the subsequent part of the suction device, in particular the carburetor flexible. Dadurch ist es möglich, den Raum um das Luftfilter für andere Aggregate auszunützen, da auf die Bewegungsfreiheit keine Rücksicht genommen werden muß. This makes it possible to exploit the space around the air filter for other aggregates because no consideration has to be made to the freedom of movement. Selbstverständlich werden auch die ungefederten Massen verringert und es ist möglich, das Luftfilter an einen geräuschmäßig günstigeren Ort anzubringen. also the unsprung masses are reduced course and it is possible to attach the air filter to a noise moderately better location.
  • 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 suction 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. A frame tube of the vehicle 1 is connected resiliently via a bellows-like sleeve 2 with the air filter 3 and thus forms a part of the intake silencer. 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. From the air filter or the intake silencer 3 a pipe 4 leading to the carburetor 5, wherein the pipe 4 is connected again via resiliently flexible couplings 6 with the two parts 3 and 5. FIG. Die Brennkraftmaschine 7 ist im nicht dargestellten Fahrzeugrahmen schwingungsfähig gelagert und weist einen Zylinder 8 auf, an dem das Abgasrohr 9 angeschlossen ist. The internal combustion engine 7 is mounted capable of oscillating in the non-illustrated vehicle frame and has a cylinder 8, to which the exhaust pipe 9 is connected.
