Abstract

A speedometer indicator field and scale are supplemented by a circular revolution rate display field and scale enclosing them. The revolution rate display uses the speedometer indicator needle which is mounted so as to rotate about the centre of both fields. Thus no individual measurement system or transducer is required, and the speed and revolution rate indicators are combined into a single instrument. The speed display field carries one or more scales corresp. to the gear ratios.

Description

Kombinierte Drehzahl-und Geschwindigkeitsmessung Combined speed and speed measurement

und Anzeige Bei Renn- und Sportwagen ist es in der Automobilbranche üblich,zu dem gesetzlich vorgeschriebenen Geschwindigkeitsmesser einen separaten Drehzahlmesser einzubauen.Bei Fahrzeugen der gehobenen Klasse gehört er genauso zur Instrumentierung wie z.B. eine Uhr. and advertisement For racing and sports cars, it is in the automotive industry It is common to have a separate speedometer in addition to the legally required speedometer It should also be installed in upscale vehicles for instrumentation such as a clock.

Diese Drehzahlmesser haben separate Messfühler am Motor(Nocken-,Kurbelwelle oder Zündverteiler).Uber einen entsprechenden Wandler werden die gezählten Impulse in die jeweilige Motordrehzahl umgesetzt und angezeigt.Beim grössten Teil der Kraftfahrzeuge,insbesonders der unteren Klassen fehlt dieses nützliche Instrument aus Kostengründen.Es kann lediglich mit entsprechendem Aufwand als Sonderzubehör nachträglich eingebaut werden.These tachometers have separate sensors on the engine (camshaft, crankshaft or ignition distributor) .The pulses counted are transmitted via an appropriate converter converted into the respective engine speed and displayed. In the majority of motor vehicles, especially the lower classes lack this useful instrument for reasons of cost can only be retrofitted as a special accessory with the corresponding effort.

In der heutigen Zeit der Energieknappheit ist es aber vor allem bei kleineren Wagen notwendig,insbesonders bei längeren Autobahnfahrten, sich immer im Bereich der günstigsten und wirtschaftlichsten Drehzahl zu bewegen.Ausserdem ist es wichtig,dass vor allem die hochverdichteten Motoren mit kleinem Hubraum nicht überdreht werden(max. zul. Drehzahl).In this day and age of energy shortage, however, it is mainly at Smaller cars are necessary, especially for longer motorway journeys, always to move in the range of the cheapest and most economical speed it is important that especially the high-compression engines with small cubic capacity do not over-revved (max. permissible speed).

Da bei allen Schaltgetrieben ja bekantlich die Motordrehzahl bei eingelegtem Gang während der Fahrt direkt proportional zur jeweiligen man Geschwindigkeit ist,könnte auf einer zweiten.entsprechnd umgerechneten Skala am Geschwindigkeitsmesser durch dieselbe Tachonadel die Drehzahl anzeigen.Dies hätte zudem den Vorteil,dass beide Werte gleichzeitig auf einem Instrument ohne wesentlichen Zusatzkosten angezeigt werden.Since with all manual transmissions the engine speed is known when the gear is engaged Gear while driving is directly proportional to the speed at which you are driving on a second, correspondingly converted scale on the speedometer the same speedometer needle show the speed. This would also have the advantage that both Values displayed simultaneously on one instrument without significant additional costs will.

Die einfachste Ausführung ist in Bild 1 gezeigt.Die Drehzahlanzeige ist hier nur auf den meisbenutzten 4. Gang bezogen.The simplest version is shown in Figure 1 is only related to the most frequently used 4th gear.

Eine andere Ausfürung mit mehreren Drehzahlskalen für verschiedene Gänge ist in Bild 2 gezeigt.Another version with several speed dials for different Gear is shown in picture 2.

Die Anordnung und Ausführung der Skalen kann dabei sehr verschieden sein.Die Anzeige erfolgt vorzugsweise analog,sie könnte jedoch durch entsprechende Anderung auch digital erfolgen.Auch zusätzliche Angaben durch Markierungen(vorzugsweise farbig) für optimalen Umschaltpunkt, wirtschaftlichste Drehzahl,max. Drehmoment e.t.c.sind auf diesen Skalen möglich.The arrangement and design of the scales can be very different The display is preferably analog, but it could be indicated by appropriate Changes can also be made digitally. Additional information by means of markings (preferably colored) for optimal switchover point, most economical speed, max. Torque e.t.c. are possible on these scales.

Da sowohl die Geschwindigkeits- wie Drchzahlanzeigemeist linear erfolgt, ist die Umrechnung relativ einfach,wie folgendes Beispiel zeigt: Es gilt: n = K *z * v mit n =Motordrehzahl (U/min) K zul. Dauerdrehzahl (Ü/min) zul. Dauerhöchstgeschw.(km/h) z =Ubersetzungsverhältniss für Getriebe v = Geschwindigkeit (km/h) Beispiel : K = 6000U/min/169km/h = 35,5 } 1. Gang z=3,764 n = 133.622*v 2. Gang z=2,02 n = 71.71*v 3. Gang z=1,32 n = 4. Gang z=1 n = 35.5*v Die beiliegenden Bilder sind nach obigem Beispiel gezeichnet.Since both the speed and the number of revolutions are mostly linear, the conversion is relatively simple, as the following example shows: The following applies: n = K * z * v with n = engine speed (rpm) K permissible continuous speed (rpm) permissible maximum continuous speed (km / h) z = transmission ratio for gearbox v = speed (km / h) Example: K = 6000rpm / 169km / h = 35.5} 1st gear z = 3.764 n = 133.622 * v 2nd gear z = 2.02 n = 71.71 * v 3rd gear z = 1.32 n = 4th gear z = 1 n = 35.5 * v The attached pictures are based on the above Example drawn.

Zur besseren Übersicht könnte die Skale im Drehzahlbereich von 5000 bis 6000 gelb 4000 bis 3000 grün 2000 bis 4000 blau über 6000 rot markiert seinFor a better overview, the scale could be in the speed range of 5000 up to 6000 yellow 4000 to 3000 green 2000 to 4000 blue over 6000 red
