Definitions
- this thrust motor comprising windings and a movable part.
- the thrust motor is used to move a switching axis to electrically connect contacts and thus to close a circuit of a starter motor.
- the movable part is also connected to a driver, which in turn interacts with an engagement lever for engaging a pinion.
- a starting device with an engaging relay in which the movable part of the engaging relay is connected to a driver that is relatively movable to the movable part.
- the engagement relay it can happen that the pinion rests on the face of the ring gear of the internal combustion engine and a contact device is switched on for switching on a starter motor of the starting device. A maximum current may flow through the contact device and thus through the starter motor, while the pinion is still in contact with the ring gear.
- an engagement relay for an electrical machine and a method for operating an electrical machine, in particular designed as a starting device, with an engagement relay having the features of the independent patent claims are proposed.
- the advantages of the invention of the engagement relay are that the proposed arrangement ensures that switching on the contact device of the engagement relay in order to switch on a starter motor of the starting device can only be closed when the pinion is at least partially engaged in the ring gear of the internal combustion engine. As a result, there is a risk that the pinion will jump over a tooth gap in the toothed ring and thereby the toothed ring or the pinion itself will no longer be damaged ("ratcheting"). By the gap or the associated stop of the stop part with the driver, the closing of the contact device is for Switching of the starter motor is prevented mechanically if the pinion is not at least partially meshed with the ring gear.
- FIG 1 a view of a starting device 10 with part of an on-board network 13 is shown schematically. Furthermore, at the left end is the Figure 1 A toothed ring 15 of an internal combustion engine 17 is shown in detail.
- the starting device 10 has an engaging relay 20, an engaging lever 22, a starter motor 23 and also, among other things, a pinion 25 Figure 1
- the part of the vehicle electrical system shown shows a power supply 27, typically referred to as a starter battery, and a start switch 28.
- the in Figure 1 The circuit shown shows the circuit or current path via which the electrical energy supply of the starting device 10 takes place.
- the engagement relay 20 is connected to a positive pole of the power supply 27 via a so-called terminal 30.
- the current then runs into the starter motor 23 via a so-called terminal 45.
- a contact bridge 50 onto what is known as a plus bolt 51 and a minus bolt 52. Then, when the start switch 28 is closed, a current flows through the positive bolt 51, the contact bridge 50 and the negative bolt 52 into the starter motor 23 and drives it at full power.
- two auxiliary contacts 53 and 54 are electrically conductively connected to one another by the contact bridge 50 or, alternatively, a similar contact. This leads to a pull-in winding 55 being energized.
- this engagement relay 20 for actuating the contact bridge 50 has an apparatus, referred to here as a thrust motor 60 with the movable part 57, which, by energizing the pull-in winding 55 and also a holding winding 63, develops a force that enables the contact bridge 50 Via the movable part 57 - preferably designed as a magnet armature - to move against various resistances (springs for example).
- FIG. 2 a more specific embodiment of the engagement relay 20 with the thrust motor 60 is shown in an initial position.
- a contact device 65 is shown, to which, inter alia, the contact bridge 50, the plus bolt 51 and the minus bolt 52 belong.
- this also includes an auxiliary contact 53 and an auxiliary contact 54.
- these two auxiliary contacts 53, 54 serve to energize a pull-in winding 55 after the start switch 28 has been closed.
- the contact bridge 50 is seated on a switching axis 67, which is passed through a magnetic yoke 70.
- the contact bridge 50 is seated on an insulating sleeve 72.
- the insulation sleeve 72 is inserted and guided in a cylindrical recess in the magnetic yoke 70.
- a contact compression spring 73 is supported at its left end and thus at an end facing away from the contact bridge 50, on a shoulder of the switching axis 67, also not designated in detail from.
- a stop element 75 rests on a pin 76 of reduced diameter.
- the stop element 75 preferably designed as a simple perforated plate - rests with a surface which is directed towards the contact bridge 50 against a bottom 77 of a blind hole-like recess 78.
- the blind hole-like recess 78 is made at one end 79 of the movable part 57. This end 79 faces away from the contact bridge 50.
- the movable part 57 has - starting from the base 77 - a through opening 80 in the manner of a through hole.
- the switching axis 67 is supported in this through opening 80 by means of a sliding bush 81.
- a contact restoring spring 82 is supported on an end face of the sliding bush 81, which is not designated in detail and which is directed towards the contact bridge 50. At another end of the contact return spring 82, the latter is supported on the magnetic yoke 70.
- a guide element 83 adjoins the end 79 of the movable part 57, which is preferably embodied here as a bushing, for example. This guide element 83 is fixed in place at its end facing the movable part 57.
- a stop part 84 and a driver 85 are arranged in this guide element 83.
- the stop part 84 and the driver 85 are held at a distance by a spring 86, which is designed here as a compression spring, for example, and by a force exerted by this spring 86.
- the driver 85 is constructed as follows: from the side facing the movable part 57, a section 87 follows, which is particularly preferred and is designed here, for example, as a ring-like collar. This section 87 has an outer circumference with a radially outwardly directed surface 88. The driver 85 is guided in the guide element 83 with this radially outwardly directed surface 88. This enables the driver 85 to be guided precisely in the guide element 83 in the direction of an axis 89 which corresponds to a direction during switching and thus the movement of the contact bridge 50 and the movement of the movable part 57. In the direction facing away from the movable part 57, the driver 85 has a section 90 which is particularly preferably designed as an annular cylinder.
- a preferably circular end face 91 At the end of the section 90 furthest away from the movable part 57 there is a preferably circular end face 91. Between this end face 91 and an end face of the stop element 75 there extends a return spring 92, which is particularly preferably designed as a compression spring. Between the end face 91 and a further end face 93 is a connecting section 94. In the direction facing away from the movable part 57, a slot 95 follows in the driver 85, which is particularly preferably designed as a longitudinal slot. A further end face 96 is located in the direction that is remote from the movable part 57, so that the slot 95 extends in the direction of the axis 89 between the two end faces 93 and 96.
- the end face 96 is followed by an end section 97, which at this point preferably connects side parts of the slot 95, preferably in one piece.
- the driver 85 thus includes, inter alia, the section 87 as a ring-like collar, the section 90, the connecting section 94, the side parts of the slot 95 and the end section 97.
- the stop part 84 is particularly preferably constructed like a disk. It has a preferably disk-like pin part 98 which itself has an end face 99 directed in the direction of the axis 89 and at the same time towards the end face 96. Also directed in the direction of the axis 89 and, in this case, aligned with the end face 93, the pin part 98 has a further end face 100. the pin part 98 extends particularly preferably between the two end faces 99 and 100. The pin part 98 is guided at its end directed in the direction of the contact bridge 50 by means of a guide device 101 in the guide element 83 in such a way that the stop part 84 carries out a preferably exclusively axial movement, which runs in the direction of the axis 89.
- the guide device 101 has two arms 102 extending from the pin part 98. Both arms 102 each have a guide section 103 which extends like a rod in the direction of the axis 89. These guide sections 103 have a surface 104 pointing away from the axis 89, ie radially outward from there, over which the stop part 84 is guided in the guide element 83 in such a way that this stop part 84 is movably guided in the direction of the axis 89 is.
- a section of the engagement lever 22 engages in the installed state of the engagement relay 20. Due to a preferred installation position of the engagement relay 20 relative to a housing of the starting device 10, the driver 85 lifts the section 87 from a stop element 110 when the engagement lever 22 is inserted into the slot 95 (distance w not equal to zero).
- FIG. 2 shows the rest position of the engagement relay 20
- Figure 3 shows Figure 3 the engaging relay 20 shortly after the engaging relay 20 is switched on with an already slightly changed position of the movable part 57.
- the stop element 75 with its surface facing the contact bridge 50 is already slightly lifted from the surface or the bottom 77 of the movable part 57. Accordingly, there is a distance d between the stop element 75 and the floor 77.
- the situation shown in this figure is intended to show a situation of the mechanics in the engaging relay 20 or in the starter or the starting device 10, in which all so-called backlashes, ie axial play in the starting device 10 or the engaging relay, up to the imminent shifting of the pinion 25 20 are used up.
- Such slack can be or are, for example, distances between the end face 99 and an upper end of the engagement lever 22. Furthermore, slacks that can act between the engagement lever 22 and a pinion shaft 106 are also possible. In this situation, a gap s between the end faces 100 and 93 is preferably still of the size that is also shown during the rest position Figure 2 present. A distance a still corresponds to a distance between the ring gear 15 and the pinion 25 in the idle state. A distance k which exists between a contact bridge 50 and the auxiliary contacts 53, 54 is still zero here. This means that the pull-in winding 55 is energized.
- the engagement relay 20 for an electrical machine which is preferably used as a starting device 10 for engaging a pinion 25, is thus disclosed.
- the engagement relay 20 has a contact device 65 for connecting electrical contacts 120, 121.
- the electrical contact 120 is connected in particular to a plus bolt 51 and the electrical contact 121 in particular to a minus bolt 52.
- the engagement relay has a thrust motor 60 which is used to move the switching axis 67.
- the thrust motor 60 has a movable part 57, which is preferably designed as a magnet armature. Accordingly, the thrust motor 60 is designed, for example, as a so-called lifting magnet.
- the movable part 57 serves to actuate the switching axis 67.
- the movable part 57 is connected to a driver 85.
- a stop part 84 is movable relative to the movable part 57 of the thrust motor 60, and when the engagement relay 20 is in a state of rest there is a gap s between the stop part 84 and the driver 85.
- a spring 86 holds the stop member 84 and the driver 85 at a distance.
- a compression spring is arranged between the stop part 84 and the driver 85. This means that it is provided in particular that the spring 86 is designed as a compression spring.
- the stop part 84 and the driver 85 are guided against one another. In particular, it is provided that the stop part 84 and the driver 85 are guided directly against one another.
- the peg part 98 is designed in particular in the manner of a plate and can therefore be guided easily in the slot 95 with the plate-like surfaces of the peg part 98. This means that the stop part 84 seated in the slot 95 cannot be rotated about the axis 89. A small torsional backlash is only possible, particularly preferably, in order to prevent an undesired blockage between the two parts.
- a pin part 98 which is designed in particular in the manner of a plate, engages in a slot 95 of the driver 85 and, as a result, the stop part 84 and the driver 85 are guided against one another.
- the stop part 84 has a radially outwardly directed surface 104, the stop part 84 being guided in the guide element 83 by means of this surface 104.
- the component driver 85 interacting with the stop part 84 has a section 87, in particular designed as a ring-like collar, which has a radially outwardly directed surface 88, the driver 85 being guided with this surface 88 in the guide element 83.
- the driver 85 has a collar-like section 87 and the switching axis 67 has a stop element 75, in particular at its end facing the driver 85, in particular carries it.
- a further stop element 110 is arranged between the collar-like section 87 and the stop element 75, which in the idle state, in particular the non-installed engagement relay 20, is a stop for the collar-like section 87 and in the switching state a stop for the further stop element 75 , in particular the switching axis 67.
- the further stop element 110 is held between the guide element 83, in particular a collar 125, of the guide element 83 designed as a bushing, and an end face 128 of the movable part 57.
- a starting device 10 with an engaging relay 20 according to one of the embodiment variants described above is provided.
- Figure 4 shows the engagement relay 20 in the starting device 10 in a situation in which a distance a between the pinion 25 and the ring gear 15 is now zero.
- the distances s and k are preferably unchanged, ie the distance for k is as already in FIG Figure 3 in principle zero, since the contact bridge 50 is in contact with the auxiliary contacts 53, 54.
- the representations of the distance k are in Figure 3 and Figure 4 symbolic.
- a pinion 25 is designed as a so-called plug-in pinion, as is the case in the exemplary embodiment, but not necessarily the case, there is a further distance m, which denotes a so-called plug-in pinion path.
- the pull-in winding 55 is energized. Since the starter motor 23 is arranged in the current path of the pull-in winding 55 and the current is so large that the starter motor 23 rotates, ultimately a pinion 25 also rotates. Furthermore, this means that the stop element 110 according to the illustration Figure 6 presses on the stop element 75. The distance d has therefore now reached its maximum. Furthermore, the distance or gap s between the two end faces 93, 100 has now decreased. In the course of the increase in the distance w or, if applicable, the emergence of the distance w, a gap or distance k not equal to zero is now also established.
- the gap s is now also compared to the previous states, which in the Figures 2 to 5 shown reduced in size.
- the driver 85 compared with the situation according to Figure 5 , its position has not changed, since the distances a and m have not changed, and the end section 97 with its end face 96 rests unchanged against the upper end of the engagement lever 22.
- a method for operating an electrical machine, in particular designed as a starter device 10, with an electrical starter motor 23 and with an engagement relay 20, wherein after the engagement relay 20 is switched on, a contact device 65 is to be actuated and a switch of the circuit of the starter motor 23 is thereby closed is, wherein a movable part 57 of a thrust motor 60 of the engaging relay '20 is connected to a driver 85 and by an engagement movement of the movable part 57 of the driver 85 on an engaging lever 22 causes an engaging force to engage a pinion 25 in a ring gear 15, wherein A stop part 84 is arranged between the movable part 57 of the thrust motor 60 and the driver 85, initially with a gap s with an initial size between the driver 85 and the stop part 84 and when moving the movable part 57 of the thrust motor 60 when switching the gap s we downsized d.
- the gap s is reduced.
- the movable part 57 of the thrust motor 60 is prevented from moving further and, as a result, further movement of the switching axis 67 and thereby closing of the contact device 65 is initially stopped.
- FIG 7 a further state of the engagement relay 20 or the starting device 10 is shown.
- This state follows the state shown in Figure 6 is shown.
- the distances a and m are still zero.
- the distance k increases, in other words, the distance between the contact bridge 50 and the contact surface of the positive pin 51 or the contact surface of the negative pin 52 becomes smaller.
- the gap s is now also zero, ie the distance between the stop part 84 and the driver 85 cannot be reduced any further.
- the distance v can accordingly no longer be increased in this situation either. This also applies to the distance w.
- a stop element 75 arranged on the switching axis 67 is placed against the stop element 110 on the movable part 57 of the thrust motor 60. Before or after the stop element 75 arranged on the switching axis 67 is applied to the stop element 110 on the movable part 57 of the thrust motor 60, the driver 85 is removed from the stop element 110 on the movable part 57 of the thrust motor 60, and thereby a spring force of the spring 86 between the stop part 84 and the driver 85 enlarged.
- a so-called “blind circuit” of the starting device 10 occurs, ie the start switch 28 has been actuated (starting device 10 switched on), but the pinion 25 cannot mesh with the ring gear 15. Accordingly, in this situation it is necessary to switch off the starting device 10 so that a holding winding 115 is switched off and does not overheat.
- Such a shutdown can either be done manually by the vehicle driver (manual opening of the Start switch 28) or by a control device, not shown here or shown in more detail, which detects this situation (no engagement of the pinion 25 in the ring gear 15 possible) and then automatically, e.g. B. after the lapse of time, temperature of a winding, such as a holding winding 115, the circuit to the starting device 10 opens.
- the movement of the movable part 57 enables the stop element 110 to move forward, so that a force continues to act on the stop element 75 and consequently also on the switching axis 67 in the direction of the contact bridge 50.
- the contact bridge 50 will touch the contact surface of the positive bolt 51 and the negative bolt 52 and thereby close the main current path of the starter motor 23.
- the movable part 57 of the thrust motor 60 is thus moved and the switch of the circuit of the starter motor 23 is thereby closed.
- the starter motor 23 will then drive the pinion 25 with maximum power and the internal combustion engine 17 can be started.

Demgegenüber soll mit den Maßnahmen der vorgeschlagenen Erfindung eine Verbesserung erzielt werden.In contrast, the measures of the proposed invention are intended to achieve an improvement.
Erfindungsgemäß werden ein Einrückrelais für eine elektrische Maschine sowie ein Verfahren zum Betreiben einer insbesondere als Startvorrichtung ausgebildeten elektrischen Maschine mit einem Einrückrelais mit den Merkmalen der unabhängigen Patentansprüche vorgeschlagen.According to the invention, an engagement relay for an electrical machine and a method for operating an electrical machine, in particular designed as a starting device, with an engagement relay having the features of the independent patent claims are proposed.
Die Vorteile der Erfindung des Einrückrelais bestehen darin, dass durch die vorgeschlagene Anordnung erreicht wird, dass ein Einschalten der Kontakteinrichtung des Einrückrelais um einen Startermotor der Startvorrichtung einzuschalten, zwingend erst dann geschlossen werden kann, wenn das Ritzel zumindest teilweise im Zahnkranz der Brennkraftmaschine eingespurt ist. Dadurch ist ein Risiko, wonach das Ritzel eine Zahnlücke im Zahnkranz überspringt und dadurch der Zahnkranz oder das Ritzel selbst beschädigt wird ("Ratschen") nicht mehr gegeben. Durch den Spalt bzw. den damit verbundenen Anschlag des Anschlagsteils mit dem Mitnehmer wird das Schließen der Kontakteinrichtung zum Schalten des Startermotors mechanisch verhindert, wenn das Ritzel in den Zahnkranz nicht zumindest teilweise eingespurt ist. Dies führt zu einer so genannten "Blindschaltung", bei der zwar beispielsweise das Zündstartschloss betätigt, aber der Starter bzw. die Startvorrichtung nicht eingeschaltet wird. Die Brennkraftmaschine wird dadurch nicht gestartet, "Ratschen" zwischen dem Ritzel und dem Zahnkranz wird verhindert. Entsprechende Vorteile gehen mit dem ebenfalls beanspruchten erfindungsgemäßen Verfahren einher.The advantages of the invention of the engagement relay are that the proposed arrangement ensures that switching on the contact device of the engagement relay in order to switch on a starter motor of the starting device can only be closed when the pinion is at least partially engaged in the ring gear of the internal combustion engine. As a result, there is a risk that the pinion will jump over a tooth gap in the toothed ring and thereby the toothed ring or the pinion itself will no longer be damaged ("ratcheting"). By the gap or the associated stop of the stop part with the driver, the closing of the contact device is for Switching of the starter motor is prevented mechanically if the pinion is not at least partially meshed with the ring gear. This leads to what is known as a "blind circuit" in which, for example, the ignition lock is actuated, but the starter or the starting device is not switched on. The internal combustion engine is not started as a result, "ratcheting" between the pinion and the ring gear is prevented. Corresponding advantages are associated with the method according to the invention, which is also claimed.

Das bewegliche Teil 57 hat - ausgehend von dem Boden 77 - eine Durchgangsöffnung 80 nach Art einer Durchgangsbohrung. In dieser Durchgangsöffnung 80 ist die Schaltachse 67 mittels einer Gleitbuchse 81 gelagert. An einer nicht näher bezeichneten Stirnfläche der Gleitbuchse 81, welche zu der Kontaktbrücke 50 gerichtet ist, stützt sich eine Kontaktrückstellfeder 82 ab. An einem anderen Ende der Kontaktrückstellfeder 82 stützt sich diese an dem magnetischen Rückschluss 70 ab. An das Ende 79 des beweglichen Teils 57 schließt sich ein Führungselement 83 an, das bevorzugt und hier beispielhaft als Buchse ausgeführt ist. Dieses Führungselement 83 ist an seinem zum beweglichen Teil 57 gerichteten Ende ortsfest befestigt. In diesem Führungselement 83 sind ein Anschlagsteil 84 und ein Mitnehmer 85 angeordnet. Das Anschlagsteil 84 und der Mitnehmer 85 sind durch eine Feder 86, welche hier beispielhaft als Druckfeder ausgeführt ist, und durch eine von dieser Feder 86 ausgeübte Kraft auf Abstand gehalten.At an
Der Mitnehmer 85 ist dabei wie folgt aufgebaut: von der Seite, welche dem beweglichen Teil 57 zugewandt ist, folgt zunächst ein Abschnitt 87, der besonders bevorzugt und hier beispielhaft als ringartiger Bund ausgeführt ist. Dieser Abschnitt 87 hat einen Außenumfang mit einer nach radial außen gerichteten Fläche 88. Mit dieser nach radial außen gerichteten Fläche 88 ist der Mitnehmer 85 in dem Führungselement 83 geführt. Dadurch ist eine präzise Führung des Mitnehmers 85 in dem Führungselement 83 in Richtung einer Achse 89 möglich, die einer Richtung beim Schalten und damit dem Bewegen der Kontaktbrücke 50 und der Bewegung des beweglichen Teils 57 entspricht. Der Mitnehmer 85 weist in sich von dem beweglichen Teil 57 abgewandter Richtung einen Abschnitt 90 auf, der besonders bevorzugt ringzylindrisch gestaltet ist. Am sich von dem beweglichen Teil 57 am weitesten entfernten Ende des Abschnitts 90, befindet sich eine bevorzugt kreisförmige Stirnfläche 91. Zwischen dieser Stirnfläche 91 und einer Stirnfläche des Anschlagelements 75 erstreckt sich eine Rückstellfeder 92, die hier besonders bevorzugt als Druckfeder ausgeführt ist. Zwischen der Stirnfläche 91 und einer weiteren Stirnfläche 93 befindet sich ein Verbindungsabschnitt 94. In die Richtung, die von dem beweglichen Teil 57 weg weist, schließt sich im Mitnehmer 85 ein Schlitz 95 an, der besonders bevorzugt als Längsschlitz ausgeführt ist. In der Richtung, die sich vom beweglichen Teil 57 entfernt, befindet sich eine weitere Stirnfläche 96, so dass sich der Schlitz 95 in Richtung der Achse 89 zwischen den beiden Stirnflächen 93 und 96 erstreckt. Der Stirnfläche 96 folgt ein Endabschnitt 97, der an dieser Stelle bevorzugt Seitenteile des Schlitzes 95 bevorzugt einstückig verbindet. Der Mitnehmer 85 umfasst somit unter anderem den Abschnitt 87 als ringartigen Bund, den Abschnitt 90, den Verbindungsabschnitt 94, die Seitenteile des Schlitzes 95 und den Endabschnitt 97.The
Das Anschlagsteil 84 ist besonders bevorzugt scheibenartig aufgebaut. Es weist einen bevorzugt scheibenartigen Zapfenteil 98 auf, der in Richtung der Achse 89 und dabei zur Stirnfläche 96 gerichtet selbst eine Stirnfläche 99 aufweist. Ebenfalls in Richtung der Achse 89 gerichtet und in diesem Fall zur Stirnfläche 93 ausgerichtet, hat das Zapfenteil 98 eine weitere Stirnfläche 100. D. h. das Zapfenteil 98 erstreckt sich besonders bevorzugt zwischen den beiden Stirnflächen 99 und 100. Das Zapfenteil 98 ist an seinem in Richtung zur Kontaktbrücke 50 gerichteten Ende mittels einer Führungseinrichtung 101 in dem Führungselement 83 derartig geführt, dass das Anschlagsteil 84 eine bevorzugt ausschließlich axiale Bewegung durchführt, die in Richtung der Achse 89 verläuft. Als besonders bevorzugte Ausführungsform weist die Führungseinrichtung 101 zwei von dem Zapfenteil 98 ausgehende Arme 102 auf. Beide Arme 102 weisen jeweils einen Führungsabschnitt 103 auf, der sich stabartig in Richtung der Achse 89 erstreckt. Diese Führungsabschnitte 103 weisen eine von der Achse 89 weg weisende, d. h. von dort nach radial außen gerichtete Oberfläche 104 auf, über die das Anschlagsteil 84 in dem Führungselement 83 so geführt ist, dass dieses Anschlagsteil 84 in der Richtung der Achse 89 beweglich und derartig geführt ist. In dem Schlitz 95, d. h. zwischen den Stirnflächen 96 und 99 greift im eingebauten Zustand des Einrückrelais 20 ein Abschnitt des Einrückhebels 22 ein. Durch eine bevorzugt gewählte Einbaulage des Einrückrelais 20 zu einem Gehäuse der Startvorrichtung 10 hebt der Mitnehmer 85 den Abschnitt 87 von einem Anschlagelement 110 ab, wenn der Einrückhebel 22 in den Schlitz 95 eingeführt wird (Abstand w ungleich Null).The
Während
Es ist somit ein Einrückrelais 20 für eine elektrische Maschine, die vorzugsweise als Startvorrichtung 10 zum Einrücken eines Ritzels 25 dient, offenbart. Das Einrückrelais 20 weist eine Kontakteinrichtung 65 zum Verbinden elektrischer Kontakte 120, 121 auf. Der elektrische Kontakt 120 ist insbesondere mit einem Plusbolzen 51 und der elektrische Kontakt 121 insbesondere mit einem Minusbolzen 52 verbunden. Es ist eine Schaltachse 67 vorhanden, die zum elektrischen Verbinden zu betätigen ist. Das Einrückrelais hat einen Schubmotor 60, der zum Verschieben der Schaltachse 67 dient. Der Schubmotor 60 hat einen beweglichen Teil 57, der vorzugsweise als Magnetanker ausgeführt ist. Dementsprechend ist der Schubmotor 60 beispielsweise als so genannter Hubmagnet ausgeführt. Der bewegliche Teil 57 dient dazu, die Schaltachse 67 zu betätigen. Der bewegliche Teil 57 ist mit einem Mitnehmer 85 verbunden. Ein Anschlagteil 84 ist relativ zum beweglichen Teil 57 des Schubmotors 60 beweglich und in einem Ruhezustand des Einrückrelais 20 ist zwischen dem Anschlagteil 84 und dem Mitnehmer 85 ein Spalt s. Eine Feder 86 hält das Anschlagteil 84 und den Mitnehmer 85 auf Abstand. Insbesondere ist vorgesehen, dass zwischen dem Anschlagteil 84 und dem Mitnehmer 85 eine Druckfeder angeordnet ist. D. h., dass insbesondere vorgesehen ist, dass die Feder 86 als Druckfeder ausgebildet ist. Des Weiteren ist vorgesehen, dass das Anschlagsteil 84 und der Mitnehmer 85 gegeneinander geführt sind. Insbesondere ist vorgesehen, dass das Anschlagteil 84 und der Mitnehmer 85 unmittelbar gegeneinander geführt sind. Das gegeneinander Führen des Anschlagteils 84 und des Mitnehmers 85 ist dadurch möglich, dass in dem Schlitz 95 des Mitnehmers 85 das Anschlagteil 84 mit dem Zapfenteil 98 geführt ist. Das Zapfenteil 98 ist insbesondere plattenartig ausgebildet und ist dadurch mit den plattenartigen Oberflächen des Zapfenteils 98 in dem Schlitz 95 gut führbar. D. h., dass das Anschlagteil 84 sitzend in dem Schlitz 95 nahezu nicht um die Achse 89 drehbar ist. Es ist lediglich besonders bevorzugt ein kleines Verdrehspiel möglich, um eine ungewollte Blockade zwischen den beiden Teilen zu verhindern. Dementsprechend ist vorgesehen, dass ein Zapfenteil 98, welcher insbesondere plattenartig ausgebildet ist, in einen Schlitz 95 des Mitnehmers 85 eingreift und dadurch das Anschlagteil 84 und der Mitnehmer 85 gegeneinander geführt sind. Insbesondere ist vorgesehen, dass das Anschlagteil 84 eine nach radial außen gerichtete Oberfläche 104 aufweist, wobei das Anschlagteil 84 mittels dieser Oberfläche 104 in dem Führungselement 83 geführt ist. Das mit dem Anschlagteil 84 wechselwirkende Bauteil Mitnehmer 85 hat einen, insbesondere als ringartigen Bund ausgebildeten Abschnitt 87, der eine nach radial außen gerichtete Fläche 88 hat, wobei der Mitnehmer 85 mit dieser Fläche 88 in dem Führungselement 83 geführt ist. Es ist insbesondere vorgesehen, dass der Mitnehmer 85 einen bundartigen Abschnitt 87 hat und die Schaltachse 67 ein Anschlagelement 75, insbesondere an ihrem zum Mitnehmer 85 gerichteten Ende, aufweist, insbesondere trägt. Des Weiteren ist vorgesehen, dass zwischen dem bundartigen Abschnitt 87 und dem Anschlagelement 75 ein weiteres Anschlagelement 110 angeordnet ist, welches im Ruhezustand, insbesondere des nicht eingebauten Einrückrelais 20, ein Anschlag für den bundartigen Abschnitt 87 und im Schaltzustand ein Anschlag für das weitere Anschlagelement 75, insbesondere der Schaltachse 67 ist. Des Weiteren ist vorgesehen, dass das weitere Anschlagelement 110 zwischen dem Führungselement 83, insbesondere einem Bund 125, des als Buchse ausgebildeten Führungselements 83, und einer Stirnfläche 128 des beweglichen Teils 57 gehalten ist. Es ist des Weiteren eine Startvorrichtung 10 mit einem Einrückrelais 20 nach einer der vorbeschriebenen Ausführungsvarianten vorgesehen.An
Wie bereits erwähnt, ist nach dem Einschalten des Startschalters 28 die Einzugswicklung 55 bestromt. Da der Startermotor 23 im Strompfad der Einzugswicklung 55 angeordnet und der Strom so groß ist, dass der Startermotor 23 sich dreht, dreht sich letztlich auch ein Ritzel 25. Des Weiteren bedeutet das, dass das Anschlagelement 110 gemäß der Darstellung nach
Es ist somit ein Verfahren zum Betreiben einer insbesondere als Startvorrichtung 10 ausgebildeten elektrischen Maschine mit einem elektrischen Startermotor 23 und mit einem Einrückrelais 20 offenbart, wobei nach dem Einschalten des Einrückrelais 20 eine Kontakteinrichtung 65 betätigt werden soll und dadurch ein Schalter des Stromkreises des Startermotors 23 geschlossen wird, wobei ein beweglicher Teil 57 eines Schubmotors 60 des Einrückrelais' 20 mit einem Mitnehmer 85 verbunden ist und durch eine Einschaltbewegung des beweglichen Teils 57 der Mitnehmer 85 auf einen Einrückhebel 22 eine Einrückraft bewirkt, um ein Ritzel 25 in einen Zahnkranz 15 einzuspuren, wobei zwischen dem beweglichen Teil 57 des Schubmotors 60 und dem Mitnehmer 85 ein Anschlagsteil 84 angeordnet ist, wobei zunächst zwischen dem Mitnehmer 85 und dem Anschlagsteil 84 ein Spalt s mit einer Anfangsgröße vorhanden ist und beim Bewegen des beweglichen Teils 57 des Schubmotors 60 beim Schalten der Spalt s verkleinert wird. Beim Bewegen des beweglichen Teils 57 des Schubmotors 60 zum Schalten wird der Spalt s so verkleinert, dass der Mitnehmer 85 am Anschlagsteil 84 anschlägt. D. h., dass das Ritzel 25 mit einem seiner Zähne an einem der Zähne des Zahnkranzes 15 anschlägt und sich danach der Spalt s verkleinert. Eine Einzugswicklung 55 des Schubmotors 60 wird bestromt. Durch das Bestromen der Einzugswicklung 55 wird der zu dieser Einzugswicklung 55 in Reihe geschaltete Startermotor 23 bestromt und dadurch das Ritzel 25 in Drehung versetzt. Beim Bewegen des beweglichen Teils 57 des Schubmotors 60 wird beim Schalten eine Schaltachse 67 verlagert, wobei ein zunächst geschlossener Schalter 56 zum Bestromen einer Einzugswicklung 55 geöffnet wird. Gegen eine Federkraft einer Feder 86 zwischen dem Anschlagsteil 84 und dem Mitnehmer 85 wird der Spalt s verkleinert. Durch das Anschlagen des Ritzels 25 am Zahnkranz 15 wird der bewegliche Teil 57 des Schubmotors 60 an einer weiteren Bewegung gehindert und dadurch eine weitere Bewegung der Schaltachse 67 und dadurch ein Schließen der Kontakteinrichtung 65 zunächst gestoppt.A method is thus disclosed for operating an electrical machine, in particular designed as a

Die in
Ist eine Dynamik des Startermotors 23 aufgrund der Bestromung über die Einzugswicklung 55 wider Erwarten aufgrund irgendwelcher Widerstände im System nicht ausreichend groß, d. h., dreht sich der Startermotor 23 nach dem Abschalten der Einzugswicklung 55 nicht mit ausreichend hoher Drehzahl bzw. nicht lange genug, so ist die typischer Weise im Läufer und einem ggf. vorhandenem Planetengetriebe zwischen Ritzel 25 und Startermotor 23 gespeicherte rotatorische Energie nicht groß genug, um Widerstände mechanischer Art zwischen dem Ritzel 25 und dessen Zähnen und den Zähnen des Zahnkranzes 15 zu überwinden, somit nicht in der Lage die Zahn-auf-Zahn-Stellung zwischen Ritzel 25 und Zahnkranz 15 zu überwinden. In einem derartigen Fall kommt es zu einer so genannten "Blindschaltung" der Startvorrichtung 10, d. h. der Startschalter 28 wurde zwar betätigt (Startvorrichtung 10 eingeschaltet), jedoch ist ein Einspuren des Ritzels 25 in den Zahnkranz 15 nicht möglich. Dementsprechend ist in dieser Situation ein Abschalten der Startvorrichtung 10 erforderlich, damit eine Haltewicklung 115 abgeschaltet wird und diese nicht überhitzt. Ein derartiges Abschalten kann entweder manuell durch den Fahrzeugführer erfolgen (manuelles Öffnen des Startschalters 28) oder durch ein hier nicht näher bezeichnetes und auch nicht näher gezeigtes Steuergerät, welches diese Situation (kein Einspuren des Ritzels 25 in den Zahnkranz 15 möglich) erkennt und dann automatisch, z. B. nach Zeitablauf, Temperatur einer Wicklung, wie beispielsweise einer Haltewicklung 115, den Stromkreis zur Startvorrichtung 10 öffnet.If, contrary to expectations, the dynamics of the
Ist andernfalls ein Vorspuren des Ritzels 25 in den Zahnkranz 15 erfolgt, so gibt das obere Ende des Einrückhebels 22 eine weitere Bewegung des Endabschnitts 97 frei, so dass sich dieser in Richtung der Achse 89 weiter - in diesem Fall nach rechts bzw. in Richtung zur Kontaktbrücke 50 - bewegen kann. Diese damit verbundene Verlagerung des Mitnehmers 85 in Richtung zur Kontaktbrücke 50 führt aufgrund der Bestromung der Haltewicklung 115 und dem daher auf den beweglichen Teil 57 wirkenden Magnetfeld und der damit verbundenen Einzugskraft in Richtung zum magnetischen Rückschluss 70 zu einer Druckkraft in Richtung zur Kontaktbrücke 50 auf den Radialbund 113 und demnach auch auf die Stirnseite der Haltearme 102. D. h., dass das Anschlagteil 84 der weiteren Bewegung des Mitnehmers 85 unmittelbar folgt. Dementsprechend ist durch die Fortbewegung des beweglichen Teils 57 eine Fortbewegung des Anschlagelements 110 möglich, so dass auf das Anschlagelement 75 und demzufolge auch auf die Schaltachse 67 eine Kraft in Richtung zur Kontaktbrücke 50 weiter wirkt. Schließlich wird die Kontaktbrücke 50 die Kontaktfläche des Plusbolzens 51 und des Minusbolzens 52 berühren und dadurch den Hauptstrompfad des Startermotors 23 schließen. Der bewegliche Teil 57 des Schubmotors 60 wird somit fortbewegt und dadurch der Schalter des Stromkreises des Startermotors 23 geschlossen. Der Startermotor 23 wird dann das Ritzel 25 mit maximaler Leistung antreiben und der Startvorgang der Brennkraftmaschine 17 kann erfolgen.Otherwise, if the
