Description
PATENTSCHRIFT Titel: Schwungradantrieb fuer Fahrzeuge. PATENT LETTERING Title: Flywheel Drive for Vehicles.
Der zu beschreibende Schwungradantrieb besteht aus zwei Schwungradgehaeusen 15, 16 welche von ihrer Seitenverkehrtheit abgesehen, innen vollkommen gleich sind.The flywheel drive to be described consists of two flywheel housings 15, 16 which, apart from their lateral wrongness, are completely identical on the inside.
Dieselben sind durch einen Verbindungsteil 17 verbunden. Jedes Schwungradgehaeuse enthaellt ein Schwungrad welches aus einem aeusseren Wulst 18 welcher durch eine Scheibe 19 mit Schaft 20 verbunden ist, besteht. Distanzscheiben 21 hallten den Wulst konzentrisch um den Schaft.They are connected by a connecting part 17. Any flywheel housing contains a flywheel which consists of an outer bead 18 which is through a Washer 19 is connected to shaft 20, there is. Spacers 21 echoed the Bead concentric around the shaft.
Der aeussere Wulst wird hier nicht naeher beschrieben, da ein aehnlicher in einer frueheren Patentschrift, einen restraining Ring betreffend, beschrieben worden ist.The outer bead is not described here in more detail, there is a similar one in an earlier patent relating to a restraining ring has been.
Schaft 20 hat an seinen Enden die Kugellager 23 und 24. - Fuer hoehere Geschwindigkeiten koennen andere als die abgebildeten Kugellager verwendet werden. ( differential Kugellager z.B. ) Schaft 20 wird ausser von den Kugellagern 23 und 24, von den permanent Magneten 22 in seinem Platz gehallten.Shank 20 has ball bearings 23 and 24 at its ends. - For hoehere Speeds other than those shown can be used. (differential ball bearings e.g.) Shank 20 is not only used by ball bearings 23 and 24, held in place by the permanent magnets 22.
Um die Reibungsverluste waehrend des Stillstandes eines mit Schwungradantrieb nach dem Erfindungsgegenstand ausgeruesteten Fahrzeuges so klein wie moeglich zu hallten, koennen die Kugellager 23 und 24 von Spannfuttern gehallten werden, welche sich bei Stillstand des Fahrzeuges oeffnen, (nicht gezeigt ) Hierdurch kann die Reibung der Kugellager waehrend des Stillstandes des Fahrzeuges vollkommen aufgehoben werden.About the friction losses during the standstill of a flywheel drive vehicle equipped according to the subject matter of the invention as small as possible echoed, the ball bearings 23 and 24 can be held by chucks, which open when the vehicle is at a standstill (not shown) Friction of the ball bearings while the vehicle is at a standstill is completely eliminated will.
Ein Vorteil des mechanischen Schwungradantriebes ist dass die Schwungraeder desselben in kuerzerer Zeit hochgedreht werden koennen als noetig ist um den Benzintank eines mittellasse Wagens zu fuellen.One advantage of the mechanical flywheel drive is that the flywheels same Can be turned up in less time than is necessary for the fuel tank to fill the medium-sized car.
Wie schnell Energie von einem energie Acumulator ( z.B. einem grossen Schwungrad ) auf die Schwungraeder des Schwungradantriebes uebertragen werden kann haengt von dem Drehmoment ab, welchem Schaft 26 ueberholkupplung 30 und Schaft 20 standhallten koennen. Die Schaefte und Ueberholkupplung koennen ohne dass dieselben wesentlich schwerer gemacht werden muessen, so gebaut werden, dass ein Hochdrehen der Schwungraeder innerhalb einer Minute moeglich wird.How quickly energy from an energy acumulator (e.g. a large Flywheel) can be transferred to the flywheels of the flywheel drive depends on the torque, which shaft 26 overrunning clutch 30 and shaft 20 can stand. The shafts and overrunning clutch can without the same must be made much heavier, built in such a way that revving the flywheels become possible within a minute.
Das Hochdrehen der Schwungraeder geht wie folgt vor sich: Zuerst greift ein innerer Konus ueber den aeusseren Konus 27 und schliesst luftdicht ab. Der innere Konus ist am Ende eines Rohres welches einen Schaft mit dem Gegenstueck des ueberstehenden Endes des Schaftes 26 einschliesst. Zur gleichen Zeit in welcher der innere Konus ueber den Konus 27 geschoben wird, kuppelt das Ende des Schaftes 26 mit seinem Gegenstueck ein, Die Luft zwischen dem Rohr mit dem Konus welcher ueber Konus 27 geschoben wird und dem Schaft welcher mit Schaft 26 einkuppelt, wird abgesaugt. Wenn das Vacuum ueber Dichtungsring 29, dem Vacuum im Schwungradgehaeuse gleich ist, wird der Dichtungsring angehoben.The flywheels are revved up as follows: First grab an inner cone over the outer cone 27 and closes airtight. The inner one The cone is at the end of a tube which has a shaft with the counterpart of the protruding one End of the shaft 26 includes. At the same time in which the inner cone Is pushed over the cone 27, the end of the shaft 26 couples with its counterpart a, the air between the tube with the cone which is pushed over cone 27 and the shaft which engages with shaft 26 is sucked off. When the vacuum About sealing ring 29, which is equal to the vacuum in the flywheel housing, is the sealing ring raised.
Dies kann mit einem Elecktomagneten welcher den Eisenring 28 der mit dem Dichtungsring verbunden ist anzieht, geschehen.This can be done with an electromagnet which the iron ring 28 with is connected to the sealing ring.
Nach dem Abheben des Dichtungsringes kann mit dem Hochdrehen des Schwungrades begonnen werden. Beide Schwungraeder des Schwungradantriebes muessen gleichzeitig hochgedreht werden.After the sealing ring has been lifted off, the flywheel can be started up to be started. Both flywheels of the flywheel drive must be at the same time be turned up.
Um zu vermeiden dass die Kreiselmomente in extremen Faellen ein mit Schwungradantrieb ausgeruestetes Fahrzeug umkippen, muessen die beiden Schwungscheiben entgegengesetzte Drehrichtungen aufweisen.In order to avoid the gyroscopic torques being reduced in extreme cases Flywheel drive equipped vehicle overturns, the two flywheels must have opposite directions of rotation.
Zum Funktionieren des Schwungradantriebes ist es absolut erlorderlich dass die beiden Schwungraeder zu jeder Zeit die gleiche Umdrehungszahl aufweisen. Die Umdrehungszahlen der Scnwungraeder koennen mit magnetischen impuls Zaehlern (nicht gezeigt) laufend aufgezeichnet werden. Sobald ein Schwungrad langsamer wird als das andere muss Elecktrizitaet vom Generator-Motor 32 des schnelleren Schwungrades zum Generator-Motor 32 des langsameren Schwungrades geleitet werden. Hierdurch wird die Drehzahl des langsameren Schwungrades erhoeht und die Drehzahl des schnelleren Schwungrades verlangsamt.It is absolutely necessary for the flywheel drive to function that the two flywheels have the same number of revolutions at all times. The number of revolutions of the flywheels can be counted with magnetic impulse counters (not shown) can be recorded continuously. As soon as a flywheel slows down the other must have electricity from the generator-motor 32 of the faster flywheel to the generator motor 32 of the slower flywheel. This will the speed of the slower flywheel increases and the speed of the faster one The flywheel slows down.
Um ein Fahrzeug mit dem Schwungradantrieb nach dem Erfindungsgegenstand anzutreiben, muessen erst die Sonnenraeder der differential Planetengetriebe-33 mit den Schwungraedern auf dieselbe Drehzahl gebracht werden. Um dies zu erreichen werden die Sonnenraeder des jeweiligen differential Planetengetriebes vermittels des Elecktromotors. 35 auf dieselbe Drehzahl wie das jeweilige Schwungrad gebracht.To a vehicle with the flywheel drive according to the subject of the invention To drive, the sun wheels of the differential planetary gear 33 be brought to the same speed with the flywheels. To achieve this the sun wheels of the respective differential planetary gear are mediated of the electric motor. 35 brought to the same speed as the respective flywheel.
Elecktrizitaet fuer Motor 35 kommt von Motor- Generator 32. Wenn die Geschwindigkeit der Sonnenraeder und der Schwungscheibe uebereinstimmt, werden dieselben vermittels der Zahnkupplung 34 gekuppelt. Der Kupplungsschieber wird vermittels der Spulen 36 elecktromagnetisch bewegt.Electricity for motor 35 comes from motor generator 32. If the Speed of the sun wheels and the flywheel coincide, become the same coupled by means of the tooth coupling 34. The coupling slide is mediated of the coils 36 moved electromagnetically.
Das differential Planetengetriebe treibt ueber nicht naeher bezeichnete Kegelraeder eine Welle (in der Zeichnung nicht zu sehen) an welche durch spezial Dichtungen hindurch zur Aussenseite des Schwungradgehaeuses gefuehrt wird. Wenn die beiden Schwungraeder entgegengesetzte Drehrichtungen haben sind auch die beiden nach aussen fuehrenden Wellen entgegengesetzt drehend. Dies ist noetig um seitlichen Bewegungen des Schwungradantriebes bei der Uebertragung von wechselnden Drehmomenten, vorzubeugen.The differential planetary gear drives over unspecified Bevel gears a shaft (not visible in the drawing) to which through special Seals is guided through to the outside of the flywheel housing. if the two flywheels have opposite directions of rotation are also the two outwardly leading shafts rotating in the opposite direction. This is necessary for lateral Movements of the flywheel drive when transmitting changing torques, to prevent.
Um den gasdynamischen Wiederstand des Schwungrades so niedrig wie moeglich zu hallten, sollte das Innere des Schwungradgehaeuses mit mit Helium gefuellt sein und unter einem wesentlich niedrigeren als dem atmospherischen Druck stehen.To keep the gas dynamic resistance of the flywheel as low as possible to echo, the inside of the flywheel housing should also with Be filled with helium and at a much lower level than atmospheric Standing under pressure.
Die Dichtung an der Austrittsstelle der Antriebswellen kann in an sich bekannter Weise aus'zwei labyrinth.Dichtungen bestehen, zwischen welchen eine Kammer ist, die ein Vacuum aufweist, welches vermittels einer Pumpe immer gleich dem Vacuum im Schwungradgehaeuse gehallten wird. Der Strohm zum Antrieb der vacuum Pumpe kommt vom Generator-Motor 32, Waehrend des Stillstandes der nach aussen fuehrenden Welle kann die Austrittsstelle derselben vermittels eines Dichtungsringes wie Ring 29 luftdicht abgeschlossen werden, Die Schmierung der Kugellager des Schaftes 26 sowie des Kugellagers 24 wird vermittels Schmierstoff welcher durch die Bohrungen 38 geleitet wird, erreicht. Dieser Schmierstoff gelangt wenn derselbe die zu schmierenden Lager passiert hat in den Raum 39 und wird von dort abgesaugt. Der Schmierstoff fuer das differential Planetengetriebe wird von Raum 40 abgesaugt.The seal at the exit point of the drive shafts can be in As is known, there are two labyrinth seals, between which one Chamber is that has a vacuum, which is always the same by means of a pump the vacuum is held in the flywheel housing. The straw to drive the vacuum The pump comes from the generator motor 32, while the one leading to the outside is at a standstill Shaft can be the exit point of the same by means of a sealing ring like ring 29 are hermetically sealed, the lubrication of the ball bearings of the shaft 26 and the ball bearing 24 is by means of lubricant which through the bores 38 is passed. This lubricant arrives when the same is the one to be lubricated Storage has passed into room 39 and is vacuumed from there. The lubricant for the differential planetary gear is extracted from space 40.
Die Ueberholkupplung 30 muss nicht unbedingt wie gezeichnet ausgefuehrt werden. Jede beruerungsfreie Ueberholkupplung welche das erforderliche Drehmoment uebertragen kann ist geeignet die gezeigte ueberholkupplung zu ersetzen.The overrunning clutch 30 does not necessarily have to be designed as shown will. Every non-contact overrunning clutch which has the required torque can transfer is suitable to replace the overrunning clutch shown.
Um eine Uebertragung ploetzlicher Fahrzeugbewegungen auf den Schwungradantrieb zu vermeiden, kann derselbe vermittels eines Kardangelenkes 25 aufgehaengt werden. Die Eigenbewegung des Schwungradantriebes kann vermittels Federn und Daempfern gedampft werden ( nicht gezeigt ).A transfer of sudden vehicle movements to the flywheel drive To avoid this, it can be suspended by means of a universal joint 25. The own movement of the flywheel drive can be dampened by means of springs and dampers (not shown).
Der Schwungradantrieb ist von einem Schutzring 37 umgeben, Die Schwungradgehaeuse muessen stark genug gebaut sein um ein auseinander fliegendes Schwungrad sicher zu hallten. Die in diesem Falle entstehende Hitze kann keinen Schaden anrichten wenn der Schwungradantrieb hinreichend isoliert ist ( mit Glasfasern z, 3. ).The flywheel drive is surrounded by a protective ring 37, the flywheel housing must be built strong enough to prevent a flywheel from flying apart to echo. The one in this The heat generated by the trap cannot cause any damage do if the flywheel drive is sufficiently insulated (with glass fibers e.g. 3.).
