Anlage ( 1) zur GebrauchsmusteranmeldungAnnex ( 1) to the utility model application
„T-MOUNT Mkl"ist ein hydraulisch gedämpfter Motorträger für großvolumige Einzylinder-Modellmotore (ab 25ccm Hubraum) mit axialer Schwingungsebene und Frontführung durch Gewindestangen. "T-MOUNT Mkl" is a hydraulically damped engine mount for large-volume single-cylinder model engines (from 25ccm displacement) with axial vibration plane and front guidance by threaded rods.
Problemproblem
Bei großvolumigen Einzylinderflugmodellmotoren werden sehr starke Vibrationen auf die Zelle des Modellflugzeuges abgegeben. Diese Vibrationen können bei Flugmodellen die zur Fernsteuerbarkeit benötigten Rudermaschinen oder sogar die elektronischen Bauteile zerstören, oder in ihrer Funktion sehr stark beeinträchtigen. Herkömmliche Systeme setzen oder hängen den Motor auf bzw. an mehrere Schwinggummis und lassen diesen „Taumeln" auf oder mit den Gummis. Daraus ergibt sich auch ein „unrunder" Propellerkreis" der auf die Flugeigenschaften des Modells einwirkt, da die Kurbelwellenspitze (= propeiieraufnanme) „eiert". Nicht gelöst ist derzeit ein weiteres Problem bei herkömmlichen Systemen: die Verstellbarkeit von Motorsturz und Seitenzug im eingebauten Zustand bei Modell-Flugzeugen. Large-volume single-cylinder model aircraft engines emit very strong vibrations into the model aircraft's airframe. These vibrations can destroy the rudder machines or even the electronic components required for remote control in model aircraft, or can severely impair their function. Conventional systems place or hang the engine on or on several rubber vibration mounts and allow it to "wobble" on or with the rubber. This also results in an "out-of-round" propeller circle, which affects the model's flight characteristics because the crankshaft tip (= propeller mount) "wobbles". Another problem with conventional systems has not yet been solved: the adjustability of the engine pitch and side pull when installed in model aircraft.
Lösung:Solution:
Die Lagerung mit einem hinter dem Motor befindlichen Schwinggummielement in der Kurbelwellenachse zwischen zwei Führungsplatten, ergibt eine axiale Schwingungsebene, die im Verbund mit der Frontführung im Bereich der Propelleraufnahme ein Taumeln verhindert. Die FrontführungThe bearing with a rubber vibration element located behind the engine in the crankshaft axis between two guide plates creates an axial vibration plane, which in conjunction with the front guide in the area of the propeller mount prevents wobbling. The front guide
Wird durch 3-6 Streben Is supported by 3-6 struts (je nach Motor) (depending on engine) gewährleistet guaranteed (s. Fotos! = 3-Streben).(see photos! = 3-struts).
a) a) der Motor schwingt um die Kurbelwellenachsethe engine oscillates around the crankshaft axis
b) Die progressive Abfederung der bewegten Massen des Motors und „erste" Dämpfung, übernimmt das Schwinggummielement, das auf Drehung (und nicht_auf zug oder Druck!) arbeitet. Zusätzliche 1~4 Öldämpfer dämpfen nach- haltig heftige Schwingungen (in der Praxis erwiesen!). b) The progressive cushioning of the moving masses of the engine and "first" damping is carried out by the rubber vibration element, which works on rotation (and not on tension or compression!) . Additional 1~4 oil dampers permanently dampen violent vibrations (proven in practice!).
c) Zylinderlage des Motors, Motorsturz und Seitenzug sind nachträglichc) Cylinder position of the engine, engine camber and side draft are subsequently
im eingebauten ZUStand korrigierbar (= Schubstreben der Frontführung sind Gewindestangen und leicht in der Länge durch heraus- oder hineindrehen zu verändern.) Can be corrected when installed (= push rods of the front guide are threaded rods and can be easily changed in length by screwing them in or out.)
d) alle Einzelteile des T-Mount's sind verschraubt und einzeln ersetzbard) all individual parts of the T-Mount are screwed and can be replaced individually
e) Kompakte Bauweise (12cm Breite!)e) Compact design (12cm width!)
f) besondere Ausfertigung des Motorträgers (s. zeichnung i) ermöglicht die Verwendung von fast allen handelsüblichen (Moden-) Motore ab 10cm3 bis 50cm3 Hubraum mit Seitenflansch und Frontvergaser (s. Fotos vom &tgr;-Mount) f) special design of the engine mount (see drawing i) allows the use of almost all commercially available (modern) engines from 10cm 3 to 50cm 3 displacement with side flange and front carburettor (see photos of the &tgr;-mount)
g) sehr hohe Dämpfung der Einzylinder-Motorschwingungeng) very high damping of single-cylinder engine vibrations
h) drei bis 6-Schraubenbefestigung ermöglicht das gesamte Aggregat mit eingebautem Motor leicht auszuwechseln.h) three to six-screw fastening allows the entire unit with built-in motor to be easily replaced.
Die bestehenden Systeme - z.B. Hydromount von Toni Clark (Lübbecke) oder der Motorträger von Metallwaren Ludwig (Bremen) - sind Motorträgersysteme für Modelimotore mit Heckflanschbefestigung und haben keine Frontführung. Ebenso wie bei anderen Systemen wird der Modellmotor auf 4-6 Schwinggummis mit und ohne Dämpfer gelagert und taumeln. In der Regel sind solche Systeme für einen oder wenige Motortypen ausgelegt. The existing systems - e.g. Hydromount by Toni Clark (Lübbecke) or the engine mount by Metallwaren Ludwig (Bremen) - are engine mount systems for model engines with rear flange mounting and have no front guide. As with other systems, the model engine is mounted on 4-6 rubber vibration mounts with and without dampers and tumbles. Such systems are usually designed for one or a few engine types.
LösungSolution
„T-Mount MkI" vermeidet alle bekannten Nachteile und zeigt deutliche Vorteile:"T-Mount MkI" avoids all known disadvantages and shows clear advantages:
a) Schwingungsarmut,a) Low vibration,
b) einfacher Aufbau >. b) simple structure >.
c) Anpassungsfähigkeit d) Justage im eingebauten Zustandc) Adaptability d) Adjustment in installed state
e) Die axiale Schwingungsebene mit progressiv dämpfendem Schwinggummi, abgestimmtem Shore-Wert und Öldämpfern, sowie der stabilen Frontführung ermöglicht eine bisher nicht gekannte „Weichheit" der Restschwingungen, die letztlich bei Einzylindermotoren nicht ganz zu vermeiden sind.e) The axial vibration plane with progressively dampening rubber, coordinated Shore value and oil dampers, as well as the stable front guide enables a previously unknown "softness" of the residual vibrations, which ultimately cannot be completely avoided in single-cylinder engines.
