Description

Beschreibungdescription
Kompressor einheitCompressor unit
Die Erfindung betrifft eine Kompressoreinheit, insbesondere zur Luftverdichtung innerhalb tragbarer / transportabler Geräte, welche mindestens einen Motor und einen über einen Schubkurbeltrieb angetriebenen Hubkolbenverdichter aufweist, wobei derThe invention relates to a compressor unit, in particular for air compression within portable / portable devices, which has at least one motor and a reciprocating compressor driven by a sliding-crank drive, wherein the
Schubkurbeltrieb aus einem Kurbelrad und einer mit Kurbelrad und einem Kolben verbundenen Pleuelstange besteht.Thrust crank mechanism consists of a crank wheel and a connecting rod connected to the crank wheel and a piston.
Bei solchen Kolbenverdichtern, insbesondere bei sehr einfachen und in großen Stückzahlen hergestellten Kolbenverdichtern wie etwa Kleinkompressoren zum Befüllen von Reifen, ist es wünschenswert, den Maximaldruck in bestimmten Grenzen zu halten, damit zum einen keine Materialüberlastung an den Kompressorbauteilen entsteht bzw. eine hohe Kompressorleistung und Lebensdauer bei wirtschaftlichem Materialeinsatz erreichbar ist und damit zum anderen eine Druckbefüllung ohne weitere teure Regeleinrichtungen nur bis zu einem Maximaldruck erfolgt.In such reciprocating compressors, especially in very simple and produced in large quantities reciprocating compressors such as small compressors for filling tires, it is desirable to keep the maximum pressure within certain limits, on the one hand, no material overload on the compressor components or high compressor performance and life can be achieved with economical use of material and thus on the other hand, a pressure filling without further expensive control devices only up to a maximum pressure.
Zur Einstellung des Maximaldruckes im Arbeitsraum des Kolbenverdichters sind einige Methoden bekannt, mit denen über eine Veränderung des Todluftvolumens eine Hubraumeinstellung und damit eine Druckeinstellung vorgenommen werden kann. Als Todluftvolumen oder auch „schädliches Volumen" bezeichnet man dabei den Teil des durch Kolbenboden und Zylinderwände begrenzten Zylindervolumens, welcher nach Vollendung des Kompressionshubes noch zwischen Kolbenboden und Zylinderwand verbleibt.To set the maximum pressure in the working space of the reciprocating compressor some methods are known with which a change in the dead volume of air displacement adjustment and thus a pressure setting can be made. The term "dead volume" or "harmful volume" refers to the part of the cylinder volume bounded by the piston crown and the cylinder walls, which still remains between the piston crown and the cylinder wall after completion of the compression stroke.
Zu diesen Methoden zählt beispielsweise die Zusammenstellung der Komponenten, nämlich Kolben, Pleuelstange, Zylinder, Zylinderkopf, mit entsprechend geeigneten Toleranzen. Dies kann jedoch nur bei ausreichend präziser Herstellung der Einzelteile erfolgreich durchgeführt werden und bleibt selbst dann ein aufwendiger Kompromiss.These methods include, for example, the composition of the components, namely piston, connecting rod, cylinder, cylinder head, with appropriate appropriate Tolerances. However, this can only be successfully carried out with sufficiently precise production of the individual parts and remains a costly compromise even then.
Eine weitere Methode ist das Einlegen von Zylinderkopfdichtungen unterschiedlicher Dicke, wodurch ebenfalls das Todluftvolumen beeinflusst werden kann. Dies ist aber im Grunde eine arbeitsintensive und lediglich schrittweise Annäherung an die richtigen Druckverhältnis se .Another method is the insertion of cylinder head gaskets of different thickness, which also the dead air volume can be influenced. However, this is basically a labor-intensive and only gradual approach to the correct pressure ratio se.
Eine weitere Lösung sind Überdruckventile im Kolbenboden oder in den Zylinderwänden, die bei einem Maximaldruck öffnen. Abgesehen von den erforderlichen zusätzlichen Bauteilen sind bei dieser Lösung die Druckschläge und die Geräuschentwicklung gelegentlich problematisch.Another solution is pressure relief valves in the piston head or in the cylinder walls, which open at a maximum pressure. Apart from the required additional components, the pressure surges and noise are occasionally problematic in this solution.
Die DE 10 2004 015 618 Al offenbart einen Axialkolbenverdichter mit variablem und regelbarem Hubraum, bei dem im Wesentlichen der Druck in der Trieb werkskammer über ein oder mehrere Regelventile in Echtzeit regelbar ist. Als Triebwerkskammer oder auch „abregelndes Volumen" wird hierbei der Raum bezeichnet, in dem der Kolbenantriebsmechanismus angeordnet ist. Die Regelung erfolgt mit Hilfe eines ein oder mehrere Betriebsparameter berücksichtigenden Algorithmus und die Regelventile sind so angeordnet, das entweder die Triebwerkskammer mit der Saugseite und/oder mit der Hochdruckseite verbunden werden kann.DE 10 2004 015 618 A1 discloses an axial piston compressor with variable and controllable displacement, in which essentially the pressure in the engine compartment can be regulated in real time via one or more control valves. The term "engine volume" is used herein to refer to the space in which the piston drive mechanism is located, controlled by an algorithm taking into account one or more operating parameters, and the control valves arranged to either the engine chamber with the intake side and / or can be connected to the high pressure side.
Hierdurch soll im Wesentlichen ein Vereisen verhindert werden, das durch zu starkes Absinken des Drucks auf der Saugseite entstehen könnte. Bei einfachen und kleinen Axialkolbenverdichtern, bei denen die Ansaugluft durch das Kolbenantriebsgehäuse des Kompressors strömt, bei denen also die Niederdruck- oder Saugseite und die Triebwerkskammer zusammenfallen, ist eine solche aufwendige Regelung nicht realisierbar.This should essentially be prevented icing, which could be caused by excessive drop in pressure on the suction side. In simple and small axial piston compressors in which the intake air flows through the piston drive housing of the compressor, ie where the low-pressure or suction side and the engine chamber coincide, such complex control is not feasible.
Zudem geht es bei den Leistungen von Kleinkompressoren weniger um die Vereisung auf der Unterdruckseite, als vielmehr darum, den Maximaldruck auf der Hochdruckseite zu begrenzen, um entweder bessere Materialauslastungen zu erreichen, oder aber um Fertigungstoleranzen für die Großserienfertigung handhabbar zu gestalten.In addition, the performance of small compressors is less about the icing on the negative pressure side, but rather about the maximum pressure on the high pressure side limit either to achieve better material utilization, or to make manageable manufacturing tolerances for mass production.
Für die Erfindung bestand also die Aufgabe, die Bauart von Kompressoren so zu gestalten, dass ohne großen Aufwand eine sehr genaue Einstellung des Maximaldruckes unabhängig von Fertigungsarten und -toleranzen erfolgen kann, sodass Nacharbeit von Bauteilen vermieden wird.So for the invention, the task was to design the design of compressors so that can be done without great effort, a very accurate adjustment of the maximum pressure regardless of manufacturing types and tolerances, so that rework of components is avoided.
Gelöst wird diese Aufgabe durch die Merkmale des Hauptanspruchs. Vorteilhafte Weiterbildungen sind in den Unteransprüchen enthalten.This object is achieved by the features of the main claim. Advantageous developments are contained in the subclaims.
Hierbei ist innerhalb des Schubkurbeltriebes, der aus einem Kurbelrad und einer mit Kurbelrad und mit einem Kolben verbundenen Pleuelstange besteht, eine Einrichtung zur Verstellung des Kolbenhubes angeordnet. Durch eine solche Ausbildung lässt sich während der Montage auf einfachste Weise der Kolbenhub und damit das verbleibende Todluftvolumen und der Maximaldruck bei gegebenen übrigen Abmessungen und Toleranzen einstellen.Here, a device for adjusting the piston stroke is arranged within the sliding crank mechanism, which consists of a crank wheel and a connecting rod connected to the crank wheel and a piston. Such a design allows the piston stroke and thus the remaining dead-air volume and the maximum pressure to be set at given remaining dimensions and tolerances in the simplest manner during installation.
Eine vorteilhafte Ausbildung besteht darin, dass zwischen Kolben und Pleuelstange eine in Schubrichtung längenverstellbare Verbindung angeordnet ist.An advantageous embodiment is that between the piston and the connecting rod an adjustable length in the direction of thrust connection is arranged.
Durch eine solche Ausbildung lässt sich bei der Montage des Kompressors durch einfache Verkürzung oder Verlängerung des Abstandes zwischen Kolbenboden und Anlenkpunkt der Pleuelstange am Kurbelrad das verbleibende Todluftvolumen und damit der Maximaldruck bei gegebenen Toleranzen einstellen.Such a design allows the remaining dead air volume and thus the maximum pressure at given tolerances set by simply shortening or lengthening the distance between the piston head and pivot point of the connecting rod on the crank wheel during assembly of the compressor.
Hiermit wird auch eine preiswerte Großserienherstellung der Bauteile durch formgebende Gießverfahren, wie z.B. durch ein Druckgussverfahren, ermöglicht, ohne dass die übliche umfangreiche Nacharbeit zur Einhaltung aller Toleranzen erforderlich wird. Eine weitere vorteilhafte Ausbildung besteht darin, dass Kolben und Pleuelstange durch eine Gewindeverbindung miteinander verbunden sind, wobei die Gewindeverbindung vorzugsweise eine Verdrehsicherung aufweist. Damit lässt sich auf einfache Art und Weise eine Funktionstrennung in Längen-Einstellung als solche und Fixierung der Längen- Einstellung erreichen.Hereby, a low-cost mass production of the components by molding casting, such as by a die-casting method allows, without the usual extensive rework to meet all tolerances is required. A further advantageous embodiment is that piston and connecting rod are connected to each other by a threaded connection, wherein the threaded connection preferably has an anti-rotation. This can be a simple way to achieve a separation of functions in length setting as such and fixing the length adjustment.
Eine weitere besonders einfach und kostengünstig zur realisierende Ausbildung besteht darin, dass die Verdrehsicherung durch eine in das Gewinde eingreifende Madenschraube erfolgt, die einen rückseitigen Werkzeugansatz aufweist. Ein Nachstellen, beispielsweise nach Probeläufen, wird hier ohne weiters möglich.Another particularly simple and inexpensive to be realized training is that the rotation takes place by a gripping screw engaging in the thread having a back tool attachment. An adjustment, for example, after trial runs, here without further possible.
Eine besonders genaue Einstellbarkeit ergibt sich bei einer Ausbildung, bei der die Gewindeverbindung als Feingewinde ausgebildet ist.A particularly accurate adjustability results in a design in which the threaded connection is formed as a fine thread.
Eine weitere vorteilhafte Ausbildung besteht darin, dass zwischen Motor und Kolbenverdichter eine Getriebeeinheit angeordnet ist, die im Wesentlichen den Schubkurbeltrieb sowie mindestens eine Zahnradstufe als Getriebestufe aufweist. Hierdurch lassen sich insbesondere in Niederspannungssystemen Motoren mit höherer Drehzahl verwenden, die dann entsprechend untersetzt werden.A further advantageous embodiment is that between the engine and piston compressor, a transmission unit is arranged, which has essentially the sliding crank drive and at least one gear stage as a gear stage. As a result, engines with higher speed can be used, in particular in low-voltage systems, which are then appropriately reduced.
In besonderer Weise geeignet ist ein solcher Kompressor innerhalb einer Vorrichtung zum Abdichten und Aufpumpen aufblasbarer Gegenstände, insbesondere zum Abdichten und Aufpumpen von Kraftfahrzeugreifen, wobei die Vorrichtung weiterhin einen Behälter für ein in den aufblasbaren Gegenstand einfüllbares selbsttätiges Dichtmittel, eine Ventil- und Verteilereinheit für Dichtmittel und Druckgas mit einer an den Kompressor anschließbaren Einlassleitung und einer an den aufblasbaren Gegenstand anschließbaren Auslassleitung, Verbindungsmittel zwischen Ventil- und Verteilereinheit und aufblasbarem Gegenstand, ggf. Verbindungsmittel zur Energiezufuhr sowie Schalt-, und/oder Steuer- und Anzeigeeinrichtungen für den Betrieb der Vorrichtung beinhaltet. In einer solchen Vorrichtung wird dann der Maximaldruck des Kolbenverdichters mit Hilfe derSuch a compressor is particularly suitable within a device for sealing and inflating inflatable articles, in particular for sealing and inflating motor vehicle tires, the device further comprising a container for a self-sealing means which can be filled in the inflatable article, a valve and distributor unit for sealing means and Compressed gas with an attachable to the compressor inlet line and an attachable to the inflatable object outlet, connecting means between the valve and distributor unit and inflatable object, possibly connecting means for supplying energy as well as switching and / or control and display devices for the operation of the device. In such a device then the maximum pressure of the reciprocating compressor with the aid of
Einrichtung zur Verstellung des Kolbenhubes auf einen Wert von 6 bis 8 bar, vorzugsweise auf einen Wert von 7 bar begrenzt. Der Vorteil einer solchen Ausführung liegt darin, dass hier speziell auf ein Fahrzeug bzw. auf eine Fahrzeugreifengröße und den entsprechenden Luftdruckbereich zugeschnittene Reparatur-Sets bereitgestellt werden, die aus völlig gleichen Einzelteilen gefertigt sind und lediglich durch Veränderung ihres Maximaldruckes über einfachste Maßnahmen auf einen bestimmten Fahrzeugtyp eingestellt werden können.Device for adjusting the piston stroke to a value of 6 to 8 bar, preferably limited to a value of 7 bar. The advantage of such an embodiment lies in the fact that repair kits tailored specifically to a vehicle or to a vehicle tire size and the corresponding air pressure area are provided, which are manufactured from completely identical individual parts and only by changing their maximum pressure via the simplest measures to a specific vehicle type can be adjusted.
