Abstract
Description
Beschreibung Warnanlage zur Übermittlung an den ahrzeugführer bei Überschreitung der zul<issi .en Höchstgeschwindigkeit, für alle mit Tachometer ausgerüsteten Automobile, Schienenfahrzeuge oder sonstige Fortbewegungsmittel durch akustisches oder optisches Signal.description Warning system to be transmitted to the driver if the maximum permitted speed is exceeded, for all automobiles, rail vehicles or other means of transport equipped with a speedometer by means of an acoustic or optical signal.
Die Einhaltung genauer Geschwindigkeiten ist besonders in den Städen, auf den Landstraßen und Autobahnen Gebot, um Unfälle zu verhindern oder acuh neuerdings Energie zu sparen.Maintaining precise speeds is particularly important in the cities on the country roads and highways is mandatory to prevent accidents or even more recently To save energy.
Bei Oberschreitung der zulässigen Höchstgeschwindigkeiten sind oft Unfälle oder empfindliche Strafen die Folge.When exceeding the maximum permissible speeds are often Accidents or severe penalties result.
Durch die Vielzahl der Reizeinflüsse ist der Fahrzeugführer nicht nur auf die Einhaltung der exakten zulässigen Geschwindigkeit eingestelle, sondern er aht eine Anzahl von Vorgangen gleichzeitig auszuführen.Due to the large number of stimuli, the vehicle driver is not only set to compliance with the exact permissible speed, but it has to perform a number of operations at the same time.
Um dem Führer des Fortbewegungsmittels, gleich welcher Art, Auf die Überschreitung des Limits aufmerksam zu machen, wird außer der sichtbaren Angabe- auf dem Tachometer, ein hörbares oder auch optisches Signal gegeben. Das Signal wird von der Tachonadel ausgelöst. Die gleichzeitige Übermittlung an Auge und Ohr warnt eindringlich bei zu hohem Bewegungsablauf.To the leader of the means of locomotion, no matter what kind, on the To draw attention to the exceeding of the limit, apart from the visible information on the speedometer, an audible or optical signal is given. The signal is triggered by the speedometer needle. The simultaneous transmission to the eye and ear warns urgently if the movement is too high.
Auf dem Fahrtgeschwindigkeitsmesser sind an den kritischen Geschwindigkeiten z.B. 50km/h, 80km/h, lOOkm/h oder auch anderen Messwerten Fotozellen angebracht, die verstellbar sein können.On the speedometer are at critical speeds e.g. 50km / h, 80km / h, 100km / h or other measured values photocells attached, which can be adjustable.
Hinter dem Tachometerglas wird ein durchsichtiger Kuststoffring, der als Zahnkranz ausgebildet ist, angebracht. Über ein Ritzel ist der Kranz von außen durch eine Reiidelschraube zu verstehen. Eine oder mehrere Lichtquellen und Fotozellen werden im Zahnkranz genau gegenüberliegend angebracht.Behind the speedometer glass is a clear plastic ring called the is designed as a ring gear, attached. The rim is on the outside via a pinion to be understood by a Reiidel screw. One or more light sources and photocells are placed exactly opposite one another in the gear rim.
Siehe Figur Nr. 1 Die arnung zum akustischen oder optischen Gerät erfolgt über die Lichtquelle, die Tachonadel und Fotozelle. Sobald die Tachonadel den Lichtstrahl unterbricht, wird das Signal gegeben. Die gewünschte darnn, z.B. für 50km/h für den Stadtverkehr, SOkm/h auf Landstraßen oder lüükm/h z.Zeit auf den Autobahnen ist einzeln einstellbar oder variabel.See figure no. 1 The warning about the acoustic or optical device takes place via the light source, the speedometer needle and photocell. As soon as the speedometer needle interrupts the light beam, the signal is given. The desired darnn, e.g. for 50km / h for city traffic, SOkm / h on country roads or lüükm / h for the moment the highways is individually adjustable or variable.
Siehe Figur 2 Toleranzwerte sind auf genaue Werte einstellbar, so daJo exakte Geschwindigkeiten in km/h oder teilen gefahren werden können.See Figure 2. Tolerance values can be set to exact values, see above daJo exact speeds in km / h or parts can be driven.
Die Überschreitung des Limits wird sofort mitg-eteilt.If the limit is exceeded, you will be notified immediately.
Das -#arnsignal wird bei kritischer Geschwindigkeit ausgelöst und kann durch Verzögerung evtl. elektronisc z.B. 2 Sekunden andauern.The - # arnsignal is triggered at critical speed and, due to a delay, can possibly last electronically, e.g. 2 seconds.
