A starting ring can be included in the integrated part.

Description

25 30 5121 564 2 Denna monteringsmetod är dyr att genomföra eftersom först måste två separata komponenter med relativt höga krav på toleranser tillverkas, och sedan måste komponentema var för sig monteras med precision. Speciellt räknarringen kräver stor precision vid monteringen på svänghjulet. This assembly method is expensive to implement because first two separate components with relatively high requirements for tolerances must be manufactured, and then the components must each be assembled with precision. The counter ring in particular requires great precision when mounting on the flywheel.

Sammanfattning av uppfinningen Föreliggande uppfinning utgör ett system för att avhjälpa nackdelarna hos kända tänd- och/eller generatorsystem. Fördelen med uppfinningen är således ett säkert och hållfast tänd- och generatorsystem, vilket är enklare och billigare att framställa och vilket kärmetecknas av att på svänghjulet anordnas en integrerad del av magnetiskt material som innefattar en kombinerad återkopplingsring och räknarring.Summary of the Invention The present invention is a system for overcoming the disadvantages of known ignition and / or generator systems. The advantage of the invention is thus a safe and durable ignition and generator system, which is simpler and cheaper to manufacture and which is characterized by the fact that an integral part of magnetic material is arranged on the flywheel which comprises a combined feedback ring and counter ring.

En betydande besparing kan erhållas med föreslagna systemet med integrerad återkopplingsring och räknarring eftersom endast en komponent behöver framställas och eftersom monteringen kan göras i ett och samma moment t ex i samband med gjutning av svänghjulet.A significant saving can be obtained with the proposed system with integrated feedback ring and counter ring because only one component needs to be manufactured and because the assembly can be done in one and the same step, for example in connection with casting of the flywheel.

Svänghjulet är företrädesvis utformat av aluminium. Zink, titan eller magnesium utgör alternativa material. Räknarringens kuggar, nockar eller liknande, som är belägna på utsidan av svänghjulet, friläggs efter gjutningen. Ett korrosionsskyddande aluminiumskikt kan dock med fördel behållas över räknarringens nockar.The flywheel is preferably made of aluminum. Zinc, titanium or magnesium are alternative materials. The teeth, cams or the like of the counter ring, which are located on the outside of the flywheel, are exposed after casting. However, a corrosion-protective aluminum layer can advantageously be retained over the cams of the counter ring.

Enligt en ytterligare utföringsforrn kan svänghjulets massa regleras genom att man varierar höjden på räknarringens nockar. Övriga särdrag hos uppfinningen framgår av de åtföljande kraven.According to a further embodiment, the mass of the flywheel can be regulated by varying the height of the cams of the counter ring. Other features of the invention appear from the appended claims.

Sammanfattningsvis är fördelama med en integrerad mät- och âterkopplingsring enligt uppfinningen följande: - hâllfastheten hos det färdiga svänghjulet är högre än vid en separat monterad räknaning eftersom räknarringen är ingjuten i och därmed en del av svänghjulet, - det är möjligt att få ett hundraprocentigt korrosionsskydd genom att behålla ett tunt aluminiumskikt på svänghjulets ytterdiameter, utanför räknarringens nockar, - svänghjulets svängmassa kan enkelt regleras och anpassas genom att variera höjden på räknarringens nockar, - arbetsinsatsen och den totala kostnaden blir betydligt lägre järnfört med det fall då två komponenter används.In summary, the advantages of an integrated measuring and feedback ring according to the invention are the following: - the strength of the finished flywheel is higher than with a separately mounted counter because the counter ring is molded into and thus part of the flywheel, to maintain a thin aluminum layer on the outer diameter of the flywheel, outside the cams of the counter ring, - the flywheel mass of the flywheel can be easily adjusted and adjusted by varying the height of the cams of the counter ring,

O:\users\KR\SEM AB\l l0006300t.doc 10 15 20 25 30 Beskrivning av utfóríngsformer Uppñnningen kommer nu att beskrivas närmare med hjälp av den åtföljande ritningen, där Figur 1 är en vy i perspektiv visande ett svänghjul i genomskärning.Description of embodiments The invention will now be described in more detail with the aid of the accompanying drawing, in which Figure 1 is a perspective view showing a flywheel in section.

Figur l visar ett svänghjul l i genomskäming. Svänghjulet är gjort av icke- magnetiskt material, företrädesvis aluminium. Även andra material är naturligtvis tänkbara, såsom zink, titan, magnesium eller andra lämpliga icke-magnetiska metaller, legeringar eller plast.Figure 1 shows a flywheel 1 in cross section. The flywheel is made of non-magnetic material, preferably aluminum. Other materials are of course also conceivable, such as zinc, titanium, magnesium or other suitable non-magnetic metals, alloys or plastics.

Svänghjulet l har forrnen av en skiva 2 med ett hål 3 för en motoraxel. Skivans periferi har en axialt sig sträckande kant 4 med en väsentligen axial inneryta och en väsentligen axial ytteryta.The flywheel 1 has the front of a disc 2 with a hole 3 for a motor shaft. The periphery of the disc has an axially extending edge 4 with a substantially axial inner surface and a substantially axial outer surface.

En integrerad del 5, som innefattar en kombinerad återkopplingsring 6 och räknarring 7, är anordnad vid svänghjulet l så att återkopplingsiingen 6 ansluter till kantens 4 inneryta. Räknarringen 7 har nockar, mätkuggar eller tänder som är vända mot svänghjulets ytteryta.An integral part 5, which comprises a combined feedback ring 6 and counter ring 7, is arranged at the flywheel 1 so that the feedback ring 6 connects to the inner surface of the edge 4. The counter ring 7 has cams, measuring teeth or teeth which face the outer surface of the flywheel.

I den visade utföringsfonnen gjuts den integrerade delen 5 på plats samtidigt som svänghjulet gjuts. Andra metoder för framställning kan även tänkas.In the embodiment shown, the integrated part 5 is cast in place at the same time as the flywheel is cast. Other methods of production are also conceivable.

Räknaningens nockar friläggs eñer gjutningen genom bearbetning av svänghjulets ytterdiameter. För att skydda nockama mot korrosion kan dock ett tunt aluminiumskikt behållas över nockama. Vissa typer av givare, t ex Hallgivare kan känna av räknarringens nockar även under ett tunt aluminiumskikt.The cams of the count are exposed after casting by machining the outer diameter of the flywheel. However, to protect the cams from corrosion, a thin layer of aluminum can be retained over the cams. Some types of sensors, such as Hall sensors, can detect the cams of the counter ring even under a thin layer of aluminum.

På insidan av den integrerade delens âterkopplingsring 6 monteras på lämpligt sätt en eller flera permanentmagneter (ej visade), t ex i form av en ring.On the inside of the feedback ring 6 of the integrated part, one or more permanent magnets (not shown) are mounted in a suitable manner, for example in the form of a ring.

Genom att variera höjden av räknarringens, 7, nockar kan man på ett enkelt sätt reglera svänghjulets massa.By varying the height of the cams of the counter ring, 7, the mass of the flywheel can be regulated in a simple manner.

I den visade utföringsformen är räknaningens, 7, nockar rektangulärt utformade, men det är uppenbart att de kan ha annan lämplig form. Nockarna kan ligga jäms med svänghjulets ytterdiameter men även skjuta ut utanför svänghjulets ytterdiameter.In the embodiment shown, the cams of the count, 7, are rectangular in shape, but it is obvious that they may have another suitable shape. The cams can be flush with the outer diameter of the flywheel but also protrude beyond the outer diameter of the flywheel.

Den integrerade delen 6 kan även innefatta en startkrans med utskjutande kuggar för samverkan med en Startmotor.The integrated part 6 may also comprise a starter ring with projecting teeth for co-operation with a starter motor.

Uppfinningen är avsedd att användas i en motor.The invention is intended for use in an engine.
