Abstract
Description
Die Erfindung betrifft einen Speicher, insbesondere ge eignet zur Aufnahme, Speicherung und Abgabe von Hydro dynamischem-Druck. Die beiden, den Speicher prägenden Gegendruckzylinder, werden auf der Energieseite durch ei ne Hydropumpe die gegen den anstehenden Gasdruck des Speichers arbeitet und so ein mechanisches Bremsmoment erzeugt mit Hydro-Druck aufgeladen, bzw. die als Tank dienende Mengenseite gleichlaufend zur Aufladung, entleert. Durch Umschalten eines Steuergliedes entnimmt die jetzt als Motor arbeitende Pumpe gespeicherten Hydro-Druck von der Energieseite des Speichers, der Motor setzt die Hydro- Energie in mechanische Bewegungsenergie um durch Erzeu gung eines Antriebsdrehmomentes, die entspannte Hydro- Flüssigkeit wird von der Mengenseite des Speichers aufge nommen. Diese Funktionsweise eines Speichers gehört bei der Betrachtung eines einzelnen Gegendruck-Zylinders zum Stand der Technik, ist aber durch konstruktive Oberar beitung der Zylinder im Detail den speziellen Anforder ungen als Energie-Mengen-Speicher angepaßt.The invention relates to a memory, in particular ge suitable for taking up, storing and dispensing Hydro dynamic pressure. The two that shape the memory Impression cylinders are on the energy side by ei ne hydraulic pump against the gas pressure of the Storage works and so a mechanical braking torque generated with hydro-pressure, or as a tank serving quantity side parallel to the charge, emptied. By switching a control element, the now takes hydraulic pressure stored as a motor pump the energy side of the store, the engine sets the hydraulic Energy into mechanical kinetic energy around by ore of a drive torque, the relaxed hydraulic Liquid is drawn up from the volume side of the reservoir taken. This is how a memory works considering a single back pressure cylinder State of the art, but is due to constructive Oberar processing of the cylinders in detail to meet the special requirements adapted as energy quantity storage.
Als technische Neuerung auf den Zylinder bezogen gelten im besonderen die Zylinderdeckel (75-86), sowie deren Sicherung auf der Hochdruckseite des Speichers durch den Segment-Ring (87). Wobei sich die einzelnen Ring-Segmente (88, 89) in der vorgesehenen Innennut des Zylinders selbst fixieren, da sie aus einem Ring gefertigt sind und diesen eingebaut wieder bilden. Durch einen mit den Zylinder deckeln von der Gegenseite verschraubten Ring (91, 92) werden diese axial über den Segment-Ring (87) bzw. den Sprengring (125) auf der Mengenseite, in Position gehalten. The cylinder covers ( 75-86 ), as well as their securing on the high-pressure side of the accumulator by the segment ring ( 87 ), are a special technical innovation related to the cylinder. The individual ring segments ( 88 , 89 ) fix themselves in the provided internal groove of the cylinder, since they are made from a ring and form it again when installed. A ring ( 91 , 92 ) screwed to the cylinder cover from the opposite side holds it in position axially via the segment ring ( 87 ) or the snap ring ( 125 ) on the quantity side.
Eine weitere technische Neuerung stellt die Zylinderver bindung der Doppelmontage dar, die es ermöglicht zwei getrennte Gegendruckzylinder mittels eines Adapterringes (90) zu einer Funktionseinheit zusammenzufügen. Der sich an den Zylinderdeckelaxialsicherungen, Segment-Ring (87) auf der Hochdruckseite und Sprengring (125) auf der Nie derdruckseite abstützende, die beiden Zylinder zueinander fixierende, bzw. über Zylinderdeckel (82) mit Zylinder deckel (76) verschraubte und damit die Zylinder axial ver bindende Ring (90) der zur Montageerleichterung durch ei nen Stift (152) seine radiale Position sucht, sowie das nachfolgend montierte Teil dies an dem Ring selbst tun kann. Der Energie-/Mengen-Speicher als eine Einheit, ist als solcher speziell dafür geeignet, ihm zugeführte Ener gie in Form von hydrostatischem Druck aufzunehmen gleich wo der Energiespender seinen Ursprung hat. Am effektivsten jedoch geschieht dies, wenn Energie die beim Bremsen frei wird in speicherbare Hydroenergie umgesetzt wird und diese dann wieder bei Bedarf etwa beim Beschleunigen wieder zur Verfügung steht. Dies erfordert jedoch eine genaue Abstim mung des Energie-/Mengen-Speichers mit der jeweiligen Ein satzmöglichkeit. So sind nachfolgende Kriterien zur Fin dung des richtigen Speichertyps von Bedeutung wie Spei chermenge, Verdichtung das heißt wieviel darf sich wäh rend eines Arbeitsspiels z. B. ein Bremsmoment verändern, welche Baumöglichkeit bietet der zur Verfügung stehende Platz für das Speicheraggregat. Dieser Speicher erfüllt diese 3 Kernfragen in einer, in jedem Teilbereich indi viduellen Gestaltungsmöglichkeiten die nahezu jede Vari ante zuläßt. So sind über die wählbaren Zylinderlängen auf der Energieseite bei Doppelmontage (15-24), bei Ein zel- und Aufbaumontage (25-34) auf der Mengenseite bei Doppelmontage (40-49), bei Einzel- und Aufbaumontage (50-59) die wichtigsten Speicherkapazitäten bzw. Fassungs vermögen abgedeckt. Das nächste Kriterium das hier gelöst wurde ist das wählbare Verdichtungsverhältnis. Es steht außer Frage, das ideale Verdichtungsverhältnis wäre 1 : 1, dieses würde gewährleisten, daß beim Gegendruckzylinder über die gesamte Hubstrecke des Kolbens der Gasdruck und somit der Öldruck konstant bliebe, dies wäre jedoch nur beim stationären Betrieb des Speichers annähernd möglich, da hier ein entsprechend großer Ausgleichdruckbehälter zur Verfügung stehen müßte. Eine praktikable Lösung sieht hier einen in seiner Länge für die interne Verdichtung wählbaren Kolben ohne Abtastungsmöglichkeit (65-69) oder mit Abtastungsmöglichkeit (70-74) vor. Ist der Aufstel lungsort in seiner Abmessung beschränkt, so besteht die Möglichkeit von externen Verdichtungsräumen für Energie- und Mengenverdichtungsraum, das heißt z. B. ein Energie-/ Mengen-Speicher mit einer kleinen Gesamtverdichtung, also mit einem großen Verdichtungsraum wird bei einem kleinen Montageraum eingesetzt, so wird der sowieso vorhandene Verdichtungsraum intern nach der kleinsten Kolbenlänge ausgelegt, während die Verdichtung gemeinsam über einen extern angeordneten, also außerhalb gelegenen Verdichtungs raum niedrig gehalten wird. Der Aufbau dieser externen Verdichtungsräume entspricht dem der Speicher, jedoch ohne Kolben. Wie dort kann auch hier das Verdichtungsvo lumen über die Teillänge beim Energieverdichtungsraum (60-64) flexibel gestaltet werden. Another technical innovation is the cylinder connection of the double assembly, which makes it possible to combine two separate impression cylinders by means of an adapter ring ( 90 ) to form a functional unit. The on the cylinder cover axial fuses, segment ring ( 87 ) on the high pressure side and snap ring ( 125 ) on the low pressure side, which fix the two cylinders to each other, or via cylinder cover ( 82 ) with cylinder cover ( 76 ) and thus screwed the cylinders axially ver binding ring ( 90 ) which searches for its radial position by a pin ( 152 ) to facilitate assembly, and the subsequently assembled part can do so on the ring itself. The energy / quantity storage as a unit, as such, is particularly suitable for absorbing the energy supplied to it in the form of hydrostatic pressure, no matter where the source of energy originates from. The most effective way to do this, however, is when energy that is released when braking is converted into storable hydro energy and is then available again when needed, for example when accelerating. However, this requires a precise coordination of the energy / quantity storage with the respective application option. The following criteria for finding the right storage type are of importance, such as the amount of storage, compression, that is, how much is allowed during a work cycle. B. change a braking torque, which construction option offers the space available for the storage unit. This memory fulfills these 3 core questions in a design option that is individual in each sub-area and that allows almost every variant. For example, the selectable cylinder lengths on the energy side for double assembly ( 15-24 ), for single and surface mounting ( 25-34 ) on the volume side for double mounting ( 40-49 ), for single and surface mounting ( 50-59 ) main storage capacities and capacities are covered. The next criterion that was solved here is the selectable compression ratio. There is no question that the ideal compression ratio would be 1: 1, this would ensure that the gas pressure and thus the oil pressure would remain constant in the counterpressure cylinder over the entire stroke length of the piston, but this would only be possible approximately with the stationary operation of the accumulator, since here appropriately large compensation pressure vessels should be available. A practical solution provides for a piston that can be selected in terms of its length for internal compression without a scanning option ( 65-69 ) or with a scanning option ( 70-74 ). Is the installation site limited in its dimensions, there is the possibility of external compression rooms for energy and volume compression space, that is z. B. an energy / volume storage with a small total compression, i.e. with a large compression space is used with a small assembly space, the compression space that is present anyway is designed internally for the smallest piston length, while the compression is carried out together via an externally arranged, i.e. outside located compression space is kept low. The structure of these external compression spaces corresponds to that of the accumulator, but without pistons. As there, the compression volume can be designed flexibly over the partial length of the energy compression room ( 60-64 ).
Als Verbindung zum Speicher ist eine feste Installation vorgesehen. Die Endstellung des Kolbens (70-74) kann durch Anbringen von Betätigungselementen (95-99, 156) an ihm und durch Montage von Endschalter-Kontrollen (140) an den Zylinderdeckeln (79, 80, 85, 86) kontrolliert werden. Somit ist es möglich, den jeweiligen Betriebsendstand "Energiespeicher leer/voll, Mengenspeicher voll/leer" sowohl als Einzelinformation abzufragen als auch als Steuerbefehl weiterzugeben. Bei Einsatz der Doppelmon tageausführung besteht aufgrund der Bauart nur die Mög lichkeit der Abfragung des leeren Energiespeichers bzw. leeren Mengenspeichers.A permanent installation is provided as a connection to the storage. The end position of the piston ( 70-74 ) can be checked by attaching actuators ( 95-99 , 156 ) to it and by installing limit switch controls ( 140 ) on the cylinder covers ( 79 , 80 , 85 , 86 ). It is thus possible to query the respective operating end status "energy storage empty / full, quantity storage full / empty" both as individual information and as a control command. When using the double-day version, due to the design, there is only the possibility of querying the empty energy store or empty quantity store.
