Definitions
- the invention relates to a compressor which is connected to a drive source by a gear transmission.
- Air compressors for commercial vehicles generally convert a rotary movement provided by the drive source (engine) of at least one piston, which moves up and down in a cylinder and compresses the air during this movement. This conversion takes place by means of a connecting rod which is rotatably mounted on the piston with a connecting rod eye and which is rotatably mounted eccentrically on a crankshaft with another connecting rod eye.
- the crankshaft is rotated by the drive source through a gear ratio.
- the gear ratio is constant so that the working speed of the compressor changes with the engine speed.
- the compressor is generally designed so that it can still supply the required compressed air requirement of the vehicle at its system pressure even when the vehicle engine is idling.
- the compressor must fit into an installation volume specified by the vehicle design, and the crankshaft must have a gearwheel for the power transmission that fits into a gearwheel present on the drive source.
- the operating parameters of the compressor are more or less fixed and must be accepted by the user, even if they are not optimal in terms of noise or energy consumption.
- a compressor In the context of the invention, a compressor was developed. This has a crankcase in which a crankshaft is rotatably mounted in a crankcase.
- the crankcase contains at least one cylinder space in which a piston, which is mounted eccentrically on the crankshaft by a connecting rod, can be excited to reciprocate.
- the crankshaft is connected to a drive source by a gear transmission that has a modulus m, in that the gearwheel arranged on the crankshaft engages in the gearwheel on the drive source.
- the axis of rotation of the crankshaft is offset from the central axis of the cylinder space by an amount d1, which is an integral multiple of m / 2.
- the central axis of the cylinder space is understood to mean the axis extending from the center of the base area of the cylinder space perpendicular to this base area, along which the piston moves.
- the transmission ratio of the transmission can be changed to an advantageous range without having to make changes to the external dimensions of the compressor or to the drive source.
- the gear of the drive source does not have to be changed. If the gear of the drive source has a number Z 1 of teeth and the meshing gear of the crankshaft has a number Z 2 of teeth, then the distance between the axes of rotation of the gears is given by m ⁇ (Z 1 + Z 2 ) / 2, where m is the modulus of the transmission. This modulus is a measure of the size of the teeth.
- the claimed offset between the axis of rotation of the crankshaft and the central axis of the cylinder space is introduced, the number of teeth Z 2 of the gear on the crankshaft and thus also the transmission ratio of the transmission can be changed without having to make changes to the drive source.
- the number of teeth remains an integral number, particularly in the case of the claimed offset, so that complex adaptation measures on the gear wheels are not required.
- the claimed feature of the integer multiple of m / 2 is not to be interpreted purely mathematically, but expressly also includes distances dl that deviate from an integer multiple of m / 2 only to such an extent that the gearwheel of the crankshaft within the mechanical tolerances can still mesh with the gear of the drive source without changes in the size of the teeth for the purpose of power transmission.
- the transmission advantageously has a transmission ratio between 1 to 0.9 and 1 to 1.1 from the drive source to the crankshaft.
- the typical motors for heavy commercial vehicles provide a gearwheel with a modulus value between 1.5 and 3.5 mm for driving a compressor.
- the gear ratio by which the number of teeth Z 2 of the gear on the crankshaft is changed can thus be changed by 2 to 3%.
- the transmission ratio is therefore advantageously greater than 1, ie Z 2 is less than Z 1 .
- the piston of the compressor moves faster. Given the specifications for the air output per unit of time (for example 200 liters per minute at 12 bar system pressure and 700 revolutions per minute of the engine), less piston stroke in the cylinder is then required to achieve this output.
- the compressor can be made more compact. Because of the limited space in the engine compartment, the piston displacement is a constant bottleneck. Typically only 360 to 400 cm 3 are available per cylinder.
- the connecting rod eye of the connecting rod which is rotatably mounted against the crankshaft, is advantageously freely movable in a circle around the axis of the crankshaft. Wear caused by bearing forces is particularly low. Furthermore, this configuration takes up particularly little space in the crankcase of the crankcase.
- the axis of rotation of the crankshaft is advantageously offset from the central axis of the cylinder space by an amount dl between 1 and 5 mm, preferably between 2 and 3 mm. Then the effect can additionally be exploited that the deflection of the connecting rod from the central axis of the cylinder is reduced when the crankshaft rotates about its axis. This deflection applies a force component to the piston, which presses against the wall of the cylinder and thus increases the wear due to friction between the cylinder and the piston.
- the invention offers the advantage that compressors of a limited range of performance classes with a high proportion of identical parts can be manufactured inexpensively.
- To adjust the power only the offset dl between the axis of rotation of the crankshaft and the central axis of the cylinder has to be adjusted.
- FIG 1 shows a schematic diagram of a compressor according to the invention.
- a cylinder bore 1a in the crankcase 1.5 Their central axis is labeled X.
- a piston 2 moves in the cylinder bore. It is connected to the crankshaft 4 via a connecting rod 3.
- the connecting rod has two connecting rod eyes 3a and 3b.
- the upper connecting rod eye 3a is rotatably supported against the piston 2.
- the lower connecting rod eye 3b is rotatably supported against a crank pin 4a which rotates with the crankshaft 4 about its central axis Y. If the crankshaft 4 rotates, the lower connecting rod eye 3b of the connecting rod 3 describes a circle around the central axis Y of the crankshaft 4.
- the axes X and Y run perpendicular to one another; the X axis runs in the drawing plane, the Y axis perpendicular to the drawing plane. However, both axes are shifted parallel to each other by an amount dl.
- the crankshaft 4 is rotatably supported against the part 5 of the crankcase 1.5.
- the effect of the parallel displacement dl is shown in the integration of the compressor into an engine compartment Figure 2 ,
- the motor block 9 with fixed dimensions is located at a predetermined location and provides a predetermined gear wheel 8 for driving the compressor.
- the gearwheel rotates about an axis Z which is perpendicular to the plane of the drawing and is at a distance A from the central axis X of the cylinder space which runs in the plane of the drawing.
- the crankshaft 4 is from driven a gear 7 that engages in the gear 8 on the engine block 9. This gear 7 rotates about the axis Y, which is the axis of symmetry of the crankshaft 4 and is perpendicular to the plane of the drawing.
- the axes Y and Z are at a distance B from one another which is smaller than the distance A.
- the gear 7 therefore has a number Z 2 of teeth which is smaller than the number Z 1 of the gear 8 on the engine block 9.
- the gear 7 thus rotates faster than the gear 8.
- the flange 6, with which it is mounted in the engine compartment, is also located at the same location as in a compressor according to the prior art, the gear 7 of which was the same size as the gear 8.

Description
Die Erfindung betrifft einen Kompressor, der durch eine Getriebeübersetzung mit einer Antriebsquelle verbunden ist.The invention relates to a compressor which is connected to a drive source by a gear transmission.
Luftkompressoren für Nutzfahrzeuge wandeln in der Regel eine von der Antriebsquelle (Motor) bereitgestellte Drehbewegung mindestens eines Kolbens um, der sich in einem Zylinder auf- und abbewegt und bei dieser Bewegung die Luft verdichtet. Diese Umwandlung geschieht durch eine Pleuelstange, die mit einem Pleuelauge am Kolben drehbar gelagert ist und die mit einem anderen Pleuelauge exzentrisch drehbar an einer Kurbelwelle gelagert ist. Die Kurbelwelle wird durch eine Getriebeübersetzung von der Antriebsquelle in Drehung versetzt. Das Übersetzungsverhältnis ist konstant, so dass die Arbeitsgeschwindigkeit des Kompressors sich mit der Motordrehzahl ändert.Air compressors for commercial vehicles generally convert a rotary movement provided by the drive source (engine) of at least one piston, which moves up and down in a cylinder and compresses the air during this movement. This conversion takes place by means of a connecting rod which is rotatably mounted on the piston with a connecting rod eye and which is rotatably mounted eccentrically on a crankshaft with another connecting rod eye. The crankshaft is rotated by the drive source through a gear ratio. The gear ratio is constant so that the working speed of the compressor changes with the engine speed.
Der Kompressor wird im Allgemeinen so ausgelegt, dass er den geforderten Druckluftbedarf des Fahrzeugs bei dessen Systemdruck auch im Leerlauf des Fahrzeugmotors noch liefern kann. Dabei muss der Kompressor in ein durch das Fahrzeugdesign vorgegebenes Einbauvolumen passen, und die Kurbelwelle muss für die Kraftübertragung ein Zahnrad aufweisen, das in ein an der Antriebsquelle vorhandenes Zahnrad passt. Die Betriebsparameter des Kompressors sind also mehr oder weniger fest vorgegeben und vom Benutzer hinzunehmen, auch wenn sie im Hinblick auf das Geräusch oder den Energieverbrauch nicht optimal sein sollten.The compressor is generally designed so that it can still supply the required compressed air requirement of the vehicle at its system pressure even when the vehicle engine is idling. The compressor must fit into an installation volume specified by the vehicle design, and the crankshaft must have a gearwheel for the power transmission that fits into a gearwheel present on the drive source. The operating parameters of the compressor are more or less fixed and must be accepted by the user, even if they are not optimal in terms of noise or energy consumption.
Aus der
Es ist daher die Aufgabe der Erfindung, einen Kompressor zur Verfügung zu stellen, der bei Vorgabe eines konkreten Einbauraumes im Motorraum und eines konkreten Zahnrades an der Antriebsquelle für die Kraftübertragung auf vorteilhaftere Betriebsparameter konfigurierbar ist. Diese Aufgabe wird erfindungsgemäß gelöst durch einen Kompressor gemäß Hauptanspruch. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den darauf rückbezogenen Unteransprüchen.It is therefore the object of the invention to provide a compressor which can be configured for more advantageous operating parameters for the power transmission when a specific installation space is specified in the engine compartment and a specific gearwheel on the drive source. This object is achieved by a compressor according to the main claim. Further advantageous configurations result from the subclaims which refer back to it.
Im Rahmen der Erfindung wurde ein Kompressor entwickelt. Dieser weist ein Kurbelgehäuse auf, in dem eine Kurbelwelle in einem Kurbelraum drehbar gelagert ist. Das Kurbelgehäuse enthält mindestens einen Zylinderraum, indem ein durch eine Pleuelstange exzentrisch an der Kurbelwelle gelagerter Kolben zu einer Hin- und Herbewebung anregbar ist. Die Kurbelwelle ist durch ein Zahnradgetriebe, dass einen Modulus m aufweist, mit einer Antriebsquelle verbunden, indem das an der Kurbelwelle angeordnete Zahnrad in das Zahnrad an der Antriebsquelle eingreift.In the context of the invention, a compressor was developed. This has a crankcase in which a crankshaft is rotatably mounted in a crankcase. The crankcase contains at least one cylinder space in which a piston, which is mounted eccentrically on the crankshaft by a connecting rod, can be excited to reciprocate. The crankshaft is connected to a drive source by a gear transmission that has a modulus m, in that the gearwheel arranged on the crankshaft engages in the gearwheel on the drive source.
Erfindungsgemäß ist die Drehachse der Kurbelwelle gegen die Mittelachse des Zylinderraums um einen Betrag dl versetzt, der ein ganzzahliges Vielfaches von m/2 ist. Unter der Mittelachse des Zylinderraums wird die vom Mittelpunkt der Grundfläche des Zylinderraums senkrecht zu dieser Grundfläche ausgehende Achse verstanden, entlang der der Kolben sich bewegt.According to the invention, the axis of rotation of the crankshaft is offset from the central axis of the cylinder space by an amount d1, which is an integral multiple of m / 2. The central axis of the cylinder space is understood to mean the axis extending from the center of the base area of the cylinder space perpendicular to this base area, along which the piston moves.
Es wurde erkannt, dass auf diese Weise das Übersetzungsverhältnis des Getriebes in einen vorteilhaften Bereich geändert werden kann, ohne das an den Außenmaßen des Kompressors oder an der Antriebsquelle Veränderungen vorgenommen werden müssen. Insbesondere muss das Zahnrad der Antriebsquelle nicht geändert werden. Wenn das Zahnrad der Antriebsquelle eine Anzahl Z1 von Zähnen hat und das darin eingreifende Zahnrad der Kurbelwelle eine Anzahl Z2 von Zähnen hat, dann ist der Abstand der Drehachsen der Zahnräder gegeben durch m∗(Z1 + Z2)/2, worin m der Modulus des Getriebes ist. Dieser Modulus ist ein Maß für die Größe der Zähne. In dem der beanspruchte Versatz zwischen der Drehachse der Kurbelwelle und der Mittelachse des Zylinderraums eingeführt wird, kann die Zahnzahl Z2 des Zahnrads an der Kurbelwelle und damit auch das Übersetzungsverhältnis des Getriebes geändert werden, ohne das an der Antriebsquelle Veränderungen vorgenommen werden müssen. Gerade bei dem beanspruchten Versatz bleibt die Zahnanzahl ganzzahlig, so dass aufwendige Anpassungsmaßnahmen an den Zahnrädern entfallen. Somit ist das beanspruchte Merkmal des ganzzahligen Vielfachen von m/2 auch nicht rein mathematisch auszulegen, sondern umfasst ausdrücklich auch noch Abstände dl, die von einem ganzzahligen Vielfachen von m/2 nur so weit abweichen, dass das Zahnrad der Kurbelwelle im Rahmen der mechanischen Toleranzen noch ohne Änderungen an der Größe der Zähne zwecks Kraftübertragung in das Zahnrad der Antriebsquelle eingreifen kann.It was recognized that in this way the transmission ratio of the transmission can be changed to an advantageous range without having to make changes to the external dimensions of the compressor or to the drive source. In particular, the gear of the drive source does not have to be changed. If the gear of the drive source has a number Z 1 of teeth and the meshing gear of the crankshaft has a number Z 2 of teeth, then the distance between the axes of rotation of the gears is given by m ∗ (Z 1 + Z 2 ) / 2, where m is the modulus of the transmission. This modulus is a measure of the size of the teeth. In that the claimed offset between the axis of rotation of the crankshaft and the central axis of the cylinder space is introduced, the number of teeth Z 2 of the gear on the crankshaft and thus also the transmission ratio of the transmission can be changed without having to make changes to the drive source. The number of teeth remains an integral number, particularly in the case of the claimed offset, so that complex adaptation measures on the gear wheels are not required. Thus, the claimed feature of the integer multiple of m / 2 is not to be interpreted purely mathematically, but expressly also includes distances dl that deviate from an integer multiple of m / 2 only to such an extent that the gearwheel of the crankshaft within the mechanical tolerances can still mesh with the gear of the drive source without changes in the size of the teeth for the purpose of power transmission.
Dabei weist das Getriebe vorteilhaft ein Übersetzungsverhältnis zwischen 1 zu 0,9 und 1 zu 1,1 von der Antriebsquelle auf die Kurbelwelle auf. Die typischen Motoren für schwere Nutzfahrzeuge stellen für den Antrieb eines Kompressors ein Zahnrad mit einem Moduluswert zwischen 1,5 und 3,5 mm bereit. Damit kann das Übersetzungsverhältnis pro Zahn, um den die Zahnanzahl Z2 des Zahnrads an der Kurbelwelle geändert wird, um 2 bis 3 % geändert werden.The transmission advantageously has a transmission ratio between 1 to 0.9 and 1 to 1.1 from the drive source to the crankshaft. The typical motors for heavy commercial vehicles provide a gearwheel with a modulus value between 1.5 and 3.5 mm for driving a compressor. The gear ratio by which the number of teeth Z 2 of the gear on the crankshaft is changed can thus be changed by 2 to 3%.
Nach dem Stand der Technik waren die Zahnanzahlen beider Zahnräder identisch, also Z1 = Z2. Wird Z2 jetzt über Z1 hinaus gesteigert, bewegt sich der Kolben im Kompressor langsamer. Damit kann das Betriebsgeräusch des Kompressors vermindert werden um den Preis, dass auch die Luftleistung pro Zeiteinheit abnimmt. Vorteilhaft ist daher das Übersetzungsverhältnis größer als 1, d.h. Z2 ist kleiner als Z1. Dann bewegt sich der Kolben des Kompressors schneller. Bei gegebenen Spezifikationen für die Luftleistung pro Zeiteinheit (beispielsweise 200 Liter pro Minute bei 12 bar Systemdruck und 700 Umdrehungen pro Minute des Motors) ist dann weniger Kolbenhub im Zylinder erforderlich, um diese Leistung zu erbringen. Der Kompressor kann kompakter ausgestaltet werden. Wegen der beengten Platzverhältnisse im Motorraum ist der Kolbenhubraum ein ständiger Engpass. Typischerweise stehen nur 360 bis 400 cm3 pro Zylinder zur Verfügung.According to the prior art, the number of teeth of both gears were identical, that is Z 1 = Z 2 If Z 2 is now increased above Z 1 , the piston in the compressor moves more slowly. The operating noise of the compressor can thus be reduced at the price that the air output per unit of time also decreases. The transmission ratio is therefore advantageously greater than 1, ie Z 2 is less than Z 1 . Then the piston of the compressor moves faster. Given the specifications for the air output per unit of time (for example 200 liters per minute at 12 bar system pressure and 700 revolutions per minute of the engine), less piston stroke in the cylinder is then required to achieve this output. The compressor can be made more compact. Because of the limited space in the engine compartment, the piston displacement is a constant bottleneck. Typically only 360 to 400 cm 3 are available per cylinder.
Vorteilhaft ist das gegen die Kurbelwelle drehbar gelagerte Pleuelauge der Pleuelstange frei in einem Kreis um die Achse der Kurbelwelle beweglich. Der Verschleiß durch Lagerkräfte ist dann besonders gering. Weiterhin beansprucht diese Ausgestaltung besonders wenig Platz im Kurbelraum des Kurbelgehäuses.The connecting rod eye of the connecting rod, which is rotatably mounted against the crankshaft, is advantageously freely movable in a circle around the axis of the crankshaft. Wear caused by bearing forces is particularly low. Furthermore, this configuration takes up particularly little space in the crankcase of the crankcase.
Vorteilhaft ist die Drehachse der Kurbelwelle gegen die Mittelachse des Zylinderraums um einen Betrag dl zwischen 1 und 5 mm, bevorzugt zwischen 2 und 3 mm, versetzt. Dann kann zusätzlich der Effekt ausgenutzt werden, dass bei der Drehung der Kurbelwelle um ihre Achse die Auslenkung der Pleuelstange aus der Mittelachse des Zylinders vermindert wird. Diese Auslenkung beaufschlagt den Kolben mit einer Kraftkomponente, die gegen die Wand des Zylinders drückt und somit den Verschleiß durch Reibung zwischen Zylinder und Kolben erhöht.The axis of rotation of the crankshaft is advantageously offset from the central axis of the cylinder space by an amount dl between 1 and 5 mm, preferably between 2 and 3 mm. Then the effect can additionally be exploited that the deflection of the connecting rod from the central axis of the cylinder is reduced when the crankshaft rotates about its axis. This deflection applies a force component to the piston, which presses against the wall of the cylinder and thus increases the wear due to friction between the cylinder and the piston.
Allgemein bietet die Erfindung den Vorteil, dass Kompressoren eines begrenzten Umfangs an Leistungsklassen mit einem hohen Gleichteilanteil kostengünstig gefertigt werden könne. Es ist zur Einstellung der Leistung lediglich der Versatz dl zwischen der Drehachse der Kurbelwelle und der Mittelachse des Zylinders anzupassen.In general, the invention offers the advantage that compressors of a limited range of performance classes with a high proportion of identical parts can be manufactured inexpensively. To adjust the power, only the offset dl between the axis of rotation of the crankshaft and the central axis of the cylinder has to be adjusted.
