AusfĂĽhrungsformen der ErfindungEmbodiments of the invention

Figur 1 zeigt eine Startvorrichtung 10 in einem Längsschnitt. Diese Startvorrichtung 10 weist beispielsweise einen Startermotor 13 und einen elektrischen Antrieb 16 (Relais, Starterrelais) auf. Der Startermotor 13 und der elektrische Antrieb 16 sind an einem gemeinsamen Antriebslagerschild 19 befestigt. Der Startermotor 13 dient funktionell dazu, ein Andrehritzel 22 anzutreiben, wenn es im Zahnkranz 25 der hier nicht dargestellten Brennkraftmaschine eingespurt ist. Figure 1 shows a starting device 10 in a longitudinal section. This starting device 10 has, for example, a starter motor 13 and an electric drive 16 (relay, starter relay). The starter motor 13 and the electric drive 16 are attached to a common drive end shield 19. The starter motor 13 functions to drive a starter pinion 22 when it is engaged in the ring gear 25 of the internal combustion engine, not shown here.

Der Startermotor 13 weist als Gehäuse ein Polrohr 28 auf, das an seinem Innenumfang Polschuhe 31 trägt, die jeweils von einer Erregerwicklung 34 umwickelt sind. Die Polschuhe 31 umgeben wiederum einen Anker 37, der ein aus Lamellen 40 aufgebautes Ankerpaket 43 und eine in Nuten 46 angeordnete Ankerwicklung 49 aufweist. Das Ankerpaket 43 ist auf eine Antriebswelle 44 aufgepresst. An dem dem Andrehritzel 22 abgewandten Ende der Antriebswelle 13 ist des Weiteren ein Kommutator 52 angebracht, der unter anderem aus einzelnen Kommutatorlamellen 55 aufgebaut ist. Die Kommutatorlamellen 55 sind in bekannterweise mit der Ankerwicklung 49 derartig elektrisch verbunden, dass sich bei Bestromung der Kommutatorlamellen 55 durch Kohlebürsten 58 eine Drehbewegung des Ankers 37 im Polrohr 28 ergibt. Eine zwischen dem elektrischen Antrieb 16 und dem Startermotor 13 angeordnete Stromzufuhr 61 versorgt im Einschaltzustand sowohl die Kohlebürsten 58 als auch die Erregerwicklung 34 mit Strom. Die Antriebswelle 13 ist kommutatorseitig mit einem Wellenzapfen 64 in einem Gleitlager 67 abgestützt, welches wiederum in einem Kommutatorlagerdeckel 70 ortsfest gehalten ist. Der Kommutatordeckel 70 wiederum wird mittels Zuganker 73, die über den Umfang des Polrohrs 28 verteilt angeordnet sind (Schrauben, beispielweise zwei, drei oder vier Stück) im Antriebslagerschild 19 befestigt. Es stützt sich dabei das Polrohr 28 am Antriebslagerschild 19 ab und der Kommutatorlagerdeckel 70 am Polrohr 28.The starter motor 13 has a pole tube 28 as a housing, which has pole shoes 31 on its inner circumference, each of which is wound by an excitation winding 34. The pole shoes 31 in turn surround an armature 37, which has an armature package 43 constructed from lamellae 40 and an armature winding 49 arranged in slots 46. The armature package 43 is pressed onto a drive shaft 44. At the end of the drive shaft 13 facing away from the starter pinion 22, a commutator 52 is furthermore attached, which is constructed, among other things, from individual commutator segments 55. The commutator fins 55 are known to be electrically connected to the armature winding 49 in such a way that when the commutator fins 55 are energized by carbon brushes 58, the armature 37 in the pole tube 28 rotates. A current supply 61 arranged between the electric drive 16 and the starter motor 13 supplies both the carbon brushes 58 and the excitation winding 34 with current in the switched-on state. The drive shaft 13 is supported on the commutator side with a shaft journal 64 in a slide bearing 67, which in turn is held stationary in a commutator bearing cover 70. The commutator cover 70 is in turn attached by means of tie rods 73, which are arranged distributed over the circumference of the pole tube 28 (screws, for example two, three or four pieces) in the drive end shield 19 attached. The pole tube 28 is supported on the drive end shield 19 and the commutator bearing cover 70 on the pole tube 28.

In Antriebsrichtung schließt sich an den Anker 37 ein sogenanntes Sonnenrad 80 an, das Teil eines Planetengetriebes 83 ist. Das Sonnenrad 80 ist von mehreren Planetenrädern 86 umgeben, üblicherweise 3 Planetenräder 37, die mittels Wälzlagern 89 auf Achszapfen 92 abgestützt sind. Die Planetenräder 37 wälzen in einem Hohlrad 95 ab, das im Polrohr 28 außenseitig gelagert ist. In Richtung zur Abtriebsseite schließt sich an die Planetenräder 37 ein Planetenträger 98 an, in dem die Achszapfen 92 aufgenommen sind. Der Planetenträger 98 wird wiederum in einem Zwischenlager 101 und einem darin angeordneten Gleitlager 104 gelagert. Das Zwischenlager 101 ist derartig topfförmig gestaltet, dass in diesem sowohl der Planetenträger 98, als auch die Planetenräder 86 aufgenommen sind. Des Weiteren ist im topfförmigen Zwischenlager 101 das Hohlrad 95 angeordnet, das letztlich durch einen Deckel 107 gegenüber dem Anker 37 geschlossen ist. Auch das Zwischenlager 101 stützt sich mit seinem Außenumfang an der Innenseite des Polrohrs 28 ab. Der Anker 37 weist auf dem vom Kommutator 52 abgewandten Ende der Antriebswelle 13 einen weiteren Wellenzapfen 110 auf, der ebenfalls in einem Gleitlager 113 aufgenommen ist, ab. Das Gleitlager 113 wiederum ist in einer zentralen Bohrung des Planetenträgers 98 aufgenommen. Der Planetenträger 98 ist einstückig mit der Abtriebswelle 116 verbunden. Diese Abtriebswelle ist mit ihrem vom Zwischenlager 101 abgewandten Ende 119 in einem weiteren Lager 122, welches im Antriebslagerschild 19 befestigt ist, abgestützt. Die Abtriebswelle 116 ist in verschiedene Abschnitte aufgeteilt: So folgt dem Abschnitt, der im Gleitlager 104 des Zwischenlagers 101 angeordnet ist, ein Abschnitt mit einer sogenannten Geradverzahnung 125 (Innenverzahnung), die Teil einer sogenannten Wellen-Nabe-Verbindung ist. Diese Welle-Nabe-Verbindung 128 ermöglicht in diesem Fall das axial geradlinige Gleiten eines Mitnehmers 131. Dieser Mitnehmer 131 ist ein hülsenartiger Fortsatz, der einstückig mit einem topfförmigen Außenring 132 des Freilaufs 137 verbunden ist. Dieser Freilauf 137 (Richtgesperre) besteht des Weiteren aus dem Innenring 140, der radial innerhalb des Außenrings 132 angeordnet ist. Zwischen dem Innenring 140 und dem Außenring 132 sind Klemmkörper 138 angeordnet. Diese Klemmkörper 138 verhindern in Zusammenwirkung mit dem Innen- und dem Außenring eine Relativdrehung zwischen dem Außenring und dem Innenring in einer zweiten Richtung. Mit anderen Worten: Der Freilauf 137 ermöglicht eine umlaufende Relativbewegung zwischen Innenring 140 und Außenring 134 nur in eine Richtung. In diesem Ausführungsbeispiel ist der Innenring 140 einstückig mit dem Andrehritzel 22 und dessen Schrägverzahnung 143 (Außenschrägverzahnung) ausgeführt. Das Andrehritzel 22 kann alternativ auch als geradverzahntes Ritzel ausgeführt sein. Statt elektromagnetisch erregter Polschuhe 31 mit Erregerwicklung 34 könnten auch permanentmagnetisch erregte Pole verwendet werden.A so-called sun gear 80, which is part of a planetary gear 83, adjoins the armature 37 in the drive direction. The sun gear 80 is surrounded by a plurality of planet gears 86, usually 3 planet gears 37, which are supported on axle journals 92 by means of roller bearings 89. The planet gears 37 roll in a ring gear 95 which is mounted on the outside in the pole tube 28. In the direction of the driven side, a planet carrier 98 adjoins the planet gears 37, in which the axle journals 92 are received. The planet carrier 98 is in turn stored in an intermediate bearing 101 and a slide bearing 104 arranged therein. The intermediate bearing 101 is designed in a cup-shaped manner such that both the planet carrier 98 and the planet gears 86 are accommodated in it. Furthermore, the ring gear 95 is arranged in the pot-shaped intermediate bearing 101 and is ultimately closed by a cover 107 with respect to the armature 37. The intermediate bearing 101 is also supported with its outer circumference on the inside of the pole tube 28. The armature 37 has a further shaft journal 110 on the end of the drive shaft 13 facing away from the commutator 52, which is also received in a slide bearing 113. The plain bearing 113 in turn is received in a central bore of the planet carrier 98. The planet carrier 98 is integrally connected to the output shaft 116. This output shaft is supported with its end 119 facing away from the intermediate bearing 101 in a further bearing 122 which is fastened in the drive end shield 19. The output shaft 116 is divided into different sections: the section which is arranged in the slide bearing 104 of the intermediate bearing 101 is followed by a section with a so-called straight toothing 125 (internal toothing) which is part of a so-called shaft-hub connection. In this case, this shaft-hub connection 128 enables a driver 131 to slide axially in a straight line. This driver 131 is a sleeve-like extension which is connected in one piece to a cup-shaped outer ring 132 of the freewheel 137. This freewheel 137 (directional lock) also consists of the inner ring 140, which is arranged radially inside the outer ring 132. Clamping bodies 138 are arranged between the inner ring 140 and the outer ring 132. In cooperation with the inner and outer rings, these clamping bodies 138 prevent a relative rotation between the outer ring and the inner ring in a second Direction. In other words: the freewheel 137 enables a circumferential relative movement between the inner ring 140 and outer ring 134 only in one direction. In this exemplary embodiment, the inner ring 140 is made in one piece with the starter pinion 22 and its helical toothing 143 (outer helical toothing). The starter pinion 22 can alternatively also be designed as a straight toothed pinion. Instead of electromagnetically excited pole shoes 31 with excitation winding 34, permanently magnetically excited poles could also be used.

Das elektrische Antrieb 16 bzw. der Anker 168 hat aber darüber hinaus auch die Aufgabe, mit einem Zugelement 187 einen dem Antriebslagerschild 19 drehbeweglich angeordneten Hebel zu bewegen. Dieser Hebel 190, üblicherweise als Gabelhebel ausgeführt, umgreift mit zwei hier nicht dargestellten "Zinken" an ihrem Außenumfang zwei Scheiben 193 und 194, um einen zwischen diesen eingeklemmten Mitnehmerring 197 zum Freilauf 137 hin gegen den Widerstand der Feder 200 zu bewegen und dadurch das Andrehritzel 22 in dem Zahnkranz 25 einzuspuren.The electric drive 16 or the armature 168 also has the task, moreover, of moving a lever which is arranged so as to be rotatable about the drive end shield 19 by means of a pulling element 187. This lever 190, usually designed as a fork lever, grips two disks 193 and 194 on its outer circumference with two “tines” (not shown here) in order to move a drive ring 197, which is clamped between them, towards the freewheel 137 against the resistance of the spring 200 and thereby the starting pinion 22 to be engaged in the ring gear 25.

Nachfolgend wird auf den Einspurmechanismus eingegangen. Der elektrische Antrieb 16 weist einen Bolzen 150 auf, der ein elektrischer Kontakt ist und im Falle des Eingebautseins im Fahrzeug an den Pluspol einer elektrischen Starterbatterie, die hier nicht dargestellt ist, angeschlossen ist. Dieser Bolzen 150 ist durch einen Deckel 153 hindurchgeführt. Ein zweiter Bolzen 152 ist ein Anschluss für den elektrischen Startermotor 13, der über die Stromzufuhr 61 (dicke Litze) versorgt wird. Dieser Deckel 153 schließt ein Gehäuse 156 aus Stahl ab, welches mittels mehrerer Befestigungselemente 159 (Schrauben) am Antriebslagerschild 19 befestigt ist. In dem elektrischen Antrieb 16 ist eine Schubeinrichtung 160 zur Ausübung einer Zugkraft auf den Gabelhebel 190 und eine Schalteinrichtung 161 angeordnet. Die Schubeinrichtung 160 hat eine Wicklung 162 und die Schalteinrichtung 161 eine Wicklung 165. Die Wicklung 162 der Schubeinrichtung 160 und die Wicklung 165 der Schalteinrichtung 161 bewirken jeweils im eingeschalteten Zustand ein elektromagnetisches Feld, welches verschiedene Bauteile durchströmt.The single-track mechanism is discussed below. The electric drive 16 has a bolt 150, which is an electrical contact and, in the case of being installed in the vehicle, is connected to the positive pole of an electric starter battery, which is not shown here. This bolt 150 is passed through a cover 153. A second bolt 152 is a connection for the electric starter motor 13, which is supplied via the power supply 61 (thick wire). This cover 153 closes a housing 156 made of steel, which is fastened to the drive end shield 19 by means of a plurality of fastening elements 159 (screws). A thrust device 160 for exerting a tensile force on the fork lever 190 and a switching device 161 are arranged in the electric drive 16. The pushing device 160 has a winding 162 and the switching device 161 has a winding 165. The winding 162 of the pushing device 160 and the winding 165 of the switching device 161 each cause an electromagnetic field in the switched-on state, which flows through various components.

Figur 2 zeigt des Weiteren: Zwischen der Wicklung 162 der Schubeinrichtung 160 und der Wicklung 165 der Schalteinrichtung 161 ist ein Zwischenteil 166 angeordnet. Dieses Zwischenteil 166 ist elektromagnetisch nicht erregbar. Beiderseits dieses Zwischenteils 166 einerseits zur Wicklung 162 und andererseits zur Wicklung 165 hin ist je ein elektromagnetisch erregbares Kernteil 167 und ein Kernteil 168 angeordnet. In diesem Ausführungsbeispiel ist das Zwischenteil 166 als kreisringförmige Platte zwischen den beiden genannten Kernteilen 167 und 168 angeordnet. Auf die Funktion dieser beiden Wicklungen im Zusammenhang mit dem Zwischenteil 166 und anderen Bauteilen wird später eingegangen. Figure 2 shows furthermore: An intermediate part 166 is arranged between the winding 162 of the pushing device 160 and the winding 165 of the switching device 161. This intermediate part 166 cannot be excited electromagnetically. On both sides of this intermediate part 166 on the one hand towards the winding 162 and on the other hand towards the winding 165, an electromagnetically excitable core part 167 and a core part 168 are arranged. In this exemplary embodiment, the intermediate part 166 is arranged as an annular plate between the two core parts 167 and 168 mentioned. The function of these two windings in connection with the intermediate part 166 and other components will be discussed later.

Das Gehäuse 156 bildet mit einem zylindrischen Abschnitt 170 seines Gehäuses, einem ringförmigen Bodenabschnitt 173, einem rohrförmigen Hals 174, einem linear beweglichen Anker, der hier als Hubmittel 176 bezeichnet ist, und dem Kernteil 167 einen elektromagnetischen Kreis 179.The housing 156 forms, with a cylindrical section 170 of its housing, an annular base section 173, a tubular neck 174, a linearly movable armature, which is referred to here as lifting means 176, and the core part 167 an electromagnetic circuit 179.

Das Gehäuse 156 bildet mit einem weiteren zylindrischen Abschnitt 180 seines Gehäuses 156, einem ringförmigen Rückschlusskern 183, der hier beispielhaft aber nicht zwingend einen zylinderringförmigen einstückig angeformten Ansatz 186 hat, einem weiteren Anker, der hier als Hubmittel 189 bezeichnet ist, und dem Kernteil 168 einen weiteren elektromagnetischen Kreis 210.The housing 156 forms with a further cylindrical section 180 of its housing 156, an annular yoke core 183, which here, for example but not necessarily, has a cylindrical ring-shaped projection 186, a further armature, which is designated here as lifting means 189, and the core part 168 another electromagnetic circuit 210.

Es ist somit ein elektrischer Antrieb 16 mit einer Schubeinrichtung 160 und einer Schalteinrichtung 161 beschrieben und gezeigt, wobei sowohl ein Hubmittel 176 der Schubeinrichtung 160 als auch ein Hubmittel 189 der Schalteinrichtung 161 mittels je eines elektromagnetischen Kreises 179, 210 zu bewegen sind.An electric drive 16 with a pushing device 160 and a switching device 161 is thus described and shown, wherein both a lifting device 176 of the pushing device 160 and a lifting device 189 of the switching device 161 can be moved by means of an electromagnetic circuit 179, 210 each.

Der elektromagnetische Kreis 179 der Schubeinrichtung 160 und der elektromagnetische Kreis 210 der Schalteinrichtung 161 sind in einem gemeinsamen elektromagnetisch erregbaren Gehäuse 156 angeordnet sind.The electromagnetic circuit 179 of the pushing device 160 and the electromagnetic circuit 210 of the switching device 161 are arranged in a common electromagnetically excitable housing 156.

Der elektromagnetische Kreis 179 der Schubeinrichtung 160 und der elektromagnetische Kreis 210 der Schalteinrichtung 161 sind durch ein elektromagnetisch nicht erregbares Zwischenteil 166 getrennt.The electromagnetic circuit 179 of the pushing device 160 and the electromagnetic circuit 210 of the switching device 161 are separated by an electromagnetically non-excitable intermediate part 166.

Beiderseits des Zwischenteils 166 ist je ein elektromagnetisch erregbares Kernteil 167, 168 angeordnet, wobei das eine Kernteil 167 ein Teil des elektromagnetischen Kreises 179 der Schubeinrichtung 160 ist und das andere Kernteil 168 Teil des elektromagnetischen Kreises 210 der Schalteinrichtung 161 ist.An electromagnetically excitable core part 167, 168 is arranged on each side of the intermediate part 166, the one core part 167 being part of the electromagnetic circuit 179 of the pushing device 160 and the other core part 168 is part of the electromagnetic circuit 210 of the switching device 161.

In Figur 3 sind Teile gezeigt, die in das Gehäuse 156 eingesetzt werden. Eine Gleithülse 213 ist mit dem Kernteil 167 verbunden (geklemmt). Hierzu ist die Gleithülse 213 auf einen im wesentlichen zylindrischen Absatz 216 des Kernteils 167 aufgeschoben. Auf der Gleithülse 213 sitzt wiederum ein Wicklungsträger 216, der zwischen zwei Seitenteilen 219 und 221 die Wicklung 162 trägt.In Figure 3 parts are shown which are inserted into the housing 156. A sliding sleeve 213 is connected (clamped) to the core part 167. For this purpose, the sliding sleeve 213 is pushed onto an essentially cylindrical shoulder 216 of the core part 167. On the sliding sleeve 213 there is in turn a winding support 216 which carries the winding 162 between two side parts 219 and 221.

Das Kernteil 167 weist einen größeren Außendurchmesser als der Wicklungsträger 216 auf. Nach radial innen erstreckt sich das Kernteil 167 mit dem Absatz 216 (erste Stufe) des Kernteils 167 in die Gleithülse 213. Nach einer weiteren Stufe erstreckt sich das Kernteil 167 mit einem geschlossenen Haubenteil 224 weiter in die Gleithülse 213. Mit diesem Haubenteil 224 erstreckt sich das Kernteil 167 in den beweglichen Anker, der hier als Hubmittel 176 bezeichnet ist, Figur 1.The core part 167 has a larger outer diameter than the winding carrier 216. The core part 167 extends radially inward with the shoulder 216 (first step) of the core part 167 into the sliding sleeve 213. After a further step, the core part 167 extends with a closed hood part 224 further into the sliding sleeve 213. With this hood part 224 extends the core part 167 in the movable armature, which is referred to here as lifting means 176, Figure 1 ,

An das Kernteil 167 schließt sich das Zwischenteil 166 an. Dieses Zwischenteil 166 weist eine zentrale Öffnung 227 auf. Diese zentrale Öffnung 227 hat zumindest in etwa den gleichen Durchmesser wie ein Durchmesser einer Kavität 230 im Kernteil 167 im Bereich einer Fuge 233, die sich zwischen dem Kernteil 167 und dem Zwischenteil 166 befindet. Von der zentralen Öffnung 227 geht nach radial außen ein Ringbereich 236 aus, der an seinem Außendurchmesser eine sich axial (Hubrichtung des/der Anker) erstreckende Nut 239 aufweist. Diese Nut 239 ist in axiale Richtung geöffnet, so dass sich eine Gleithülse 242 in diese Nut 239 erstreckt. Die Nut 239 geht mit ihrem Außenumfang in eine nicht näher bezeichnete innenzylindrische Oberfläche des Zwischenteils 166 über, an der die Gleithülse 242 gestützt anliegt. Das Zwischenteil 166 trägt somit in einem Ringbereich 236 eine Gleithülse 242 trägt.The intermediate part 166 adjoins the core part 167. This intermediate part 166 has a central opening 227. This central opening 227 has at least approximately the same diameter as a diameter of a cavity 230 in the core part 167 in the region of a joint 233 which is located between the core part 167 and the intermediate part 166. An annular region 236 extends radially outward from the central opening 227 and has a groove 239 extending axially (stroke direction of the armature (s)) on its outer diameter. This groove 239 is opened in the axial direction, so that a sliding sleeve 242 extends into this groove 239. The groove 239 merges with its outer circumference into an unspecified inner cylindrical surface of the intermediate part 166, against which the sliding sleeve 242 is supported. The intermediate part 166 thus carries a sliding sleeve 242 in an annular region 236.

Dem Zwischenteil 166 folgt in axialer Richtung das Kernteil 168, das in diesem Ausführungsbeispiel eben ringzylindrisch ausgeführt ist. Ein Außendurchmesser des Kernteils 168 ist größer als ein Außendurchmesser des Zwischenteils 166 und der Außendurchmesser des Kernteils 167. Auf der Gleithülse 242 sitzt somit das zweite Kernteil 168.The intermediate part 166 is followed in the axial direction by the core part 168, which in this exemplary embodiment is also of a ring-cylindrical design. An outer diameter of the core part 168 is larger than an outer diameter of the intermediate part 166 and the outer diameter of the core part 167. The second core part 168 is thus seated on the sliding sleeve 242.

Auf das Kernteil 168 folgt in axialer Richtung auf der Gleithülse 242 sitzend wiederum ein Wicklungsträger 245, der zwischen zwei Seitenteilen 248 und 251 die Wicklung 165 trägt. Auf der Gleithülse 242 sitzt ein weiterer Wicklungsträger 245 mit einer elektrischen Wicklung 165 sitzt.The core part 168 is followed in the axial direction on the sliding sleeve 242 by a winding carrier 245 which carries the winding 165 between two side parts 248 and 251. Another winding carrier 245 with an electrical winding 165 is seated on the sliding sleeve 242.

Im Gegensatz zum Wicklungsträger 216 weist der Wicklungsträger 245 eine Besonderheit auf: Auf dem Wicklungsträger 245 ist nicht nur die Wicklung 165 aufgewickelt, sondern auch eine Wicklung 254, die in Bezug zum Hubmittel 189 im Betrieb als eine Haltewicklung fungiert. Hierauf wird später noch eingegangen.In contrast to the winding carrier 216, the winding carrier 245 has a special feature: not only the winding 165 is wound on the winding carrier 245, but also a winding 254, which functions as a holding winding in relation to the lifting means 189 during operation. This will be discussed later.

Am in Figur 3 rechten Ende des dargestellten Gegenstands erstrecken sich zwei elektrische Anschlüsse 257 und 260, die zur Stromversorgung der Wicklung 162 (mit der Wicklung 254 und der Wicklung 165 dienen. Die Anschlüsse 257 und 260 sind mit zwei durch den Deckel 153 hindurchragenden Kontakten (Flachstecker) 263 und 266 elektrisch leitfähig verbunden, Figur 1. Mittels der Kontakte 263 und 266 ist von außen eine Ansteuerung der genannten Wicklungen möglich.On in Figure 3 On the right end of the object shown, two electrical connections 257 and 260 extend, which serve to supply current to the winding 162 (with the winding 254 and the winding 165. The connections 257 and 260 are provided with two contacts (tab connectors) 263 and 266 electrically connected, Figure 1 , The contacts 263 and 266 can be used to actuate the windings mentioned from the outside.

Es ist somit ein elektrischer Antrieb 16 gezeigt, dessen Kernteil 167, welches Teil des elektromagnetischen Kreises 179 der Schubeinrichtung 160 ist, eine in Richtung zum Hubmittel 189 der Schalteinrichtung 161 konkave Form mit einer Kavität 230 aufweist. In die Kavität 230 ragt eine Schaltachse 269 der Schalteinrichtung 161. Je näher ein Oberflächenabschnitt der Kavität 230 der Fuge 233 angeordnet ist, desto größer ist ein Winkel zwischen dem Oberflächenabschnitt und einer Achse 272.An electrical drive 16 is thus shown, whose core part 167, which is part of the electromagnetic circuit 179 of the pushing device 160, has a concave shape with a cavity 230 in the direction of the lifting means 189 of the switching device 161. A switching axis 269 of the switching device 161 protrudes into the cavity 230. The closer a surface section of the cavity 230 to the joint 233 is arranged, the greater the angle between the surface section and an axis 272.

In Figur 4 ist das Gehäuse 156 über das bereits zu Figur 1 Erwähnte näher beschrieben. So ist das Gehäuse 156 an der Startvorrichtung 10 bis auf einen Bördelrand 275 (Figur 1) und den rohrförmigen Hals 174 zylindrisch. Im ringförmigen Bodenabschnitt 173 befinden sich Durchgangsöffnungen 278, von denen in Figur 4 eine dargestellt ist. Diese Durchgangsöffnungen 278 haben ein Innengewinde und nehmen die Befestigungselemente 159 (Schrauben) auf. Von einem, dem rohrförmigen Hals 174 (erstes Ende) in Richtung der Achse 272 abgewandten Ende ausgehend, beginnt das Gehäuse 156 zunächst mit einem schmalen Randbereich, der dem späteren Bördelrand 275 entspricht. Diesem Abschnitt folgt mit in diesem Fall gleichem Innendurchmesser eine vorzugsweise zylindrische Aufnahme 281 an der ein Bördelabsatz 284 (Figur 1) des Deckels 153, gefolgt von einer ringförmigen Dichtung 153, und der ringförmige Rückschlusskern 183 mit seinem Außendurchmesser passend aufgenommen wird. Der ringförmige Rückschlusskern 183 liegt an einer Stirnfläche 290 eines Absatzes 293 an. Diesem Absatz 293 folgt ein gegenüber der vorzugsweise zylindrischen Aufnahme 281 im Innendurchmesser kleinerer Abschnitt 296 (erster Wicklungsabschnitt), der die Wicklung 165 überdeckt. Dem Abschnitt 296 folgt ein nach trichterförmiger Abschnitt 299. Dieser trichterförmige Abschnitt 299 dient dazu, den Kernteil 167, das Zwischenteil 166 und den Kernteil 168 zu zentrieren. Nach dem trichterförmigen Abschnitt 299 folgt eine Passzone 302, in der das Kernteil 168 mit einer Presspassung (Übermaß der Presspassung 0,1 bis 0,3 mm, je nach Toleranzlage der Teile zueinander eingefügt ist. Danach folgt eine Passzone 305, in der das Kernteil 167 mit einer Presspassung (Übermaß der Presspassung 0,1 bis 0,3 mm, je nach Toleranzlage der Teile zueinander) eingefügt ist. Für den Fall, dass zwischen den beiden Passzonen 302 und 305 keine weitere Zone ist, ist ein Übergang der Passzonen 302 und 305 dort, wo das Zwischenteil 166 angeordnet ist. Der Passzone 305 folgt ein trichterförmiger Abschnitt 309, der dazu dient, den Wicklungsträger 216 in einen die Wicklung 162 überdeckenden Bereich 312 zu zentrieren.In Figure 4 the housing 156 is already closed Figure 1 Described in more detail. For example, the housing 156 on the starting device 10 is up to a flanged edge 275 ( Figure 1 ) and the tubular neck 174 cylindrical. In the annular bottom section 173 there are through openings 278, of which in Figure 4 one is shown. These through openings 278 have an internal thread and receive the fastening elements 159 (screws). Starting from an end facing away from the tubular neck 174 (first end) in the direction of the axis 272, the housing 156 initially begins with a narrow edge region which corresponds to the later flanged edge 275. This section, in this case with the same inner diameter, is followed by a preferably cylindrical receptacle 281 on which a flanged shoulder 284 ( Figure 1 ) of Lid 153, followed by an annular seal 153, and the annular yoke core 183 is received with its outer diameter to match. The annular yoke core 183 abuts an end face 290 of a shoulder 293. This shoulder 293 is followed by a section 296 (first winding section) which is smaller in the inside diameter than the preferably cylindrical receptacle 281 and which covers the winding 165. Section 296 is followed by a funnel-shaped section 299. This funnel-shaped section 299 serves to center the core part 167, the intermediate part 166 and the core part 168. After the funnel-shaped section 299 there follows a fitting zone 302, in which the core part 168 is inserted with an interference fit (excess of the interference fit 0.1 to 0.3 mm, depending on the tolerance position of the parts to one another. This is followed by a fitting zone 305, in which the core part 167 is inserted with a press fit (oversize of the press fit 0.1 to 0.3 mm, depending on the tolerance position of the parts relative to one another). In the event that there is no further zone between the two fitting zones 302 and 305, there is a transition of the fitting zones 302 and 305 where the intermediate part 166 is arranged. The fitting zone 305 is followed by a funnel-shaped section 309 which serves to center the winding carrier 216 in an area 312 covering the winding 162.

Es ist somit vorgesehen, dass das Kernteil 167 des elektromagnetischen Kreises 179 der Schubeinrichtung 160 mit Druck an einer Passzone 305 des elektromagnetisch erregbaren Gehäuses 156 anliegt.It is thus provided that the core part 167 of the electromagnetic circuit 179 of the thrust device 160 bears with pressure against a fitting zone 305 of the electromagnetically excitable housing 156.

Es ist somit vorgesehen, dass das Kernteil 168 des elektromagnetischen Kreises 210 der Schalteinrichtung 161 mit Druck an einer Passzone 305 des elektromagnetisch erregbaren Gehäuses 156 anliegt.It is thus provided that the core part 168 of the electromagnetic circuit 210 of the switching device 161 presses against a fitting zone 305 of the electromagnetically excitable housing 156.

Durch die Passzone 302 wird es ermöglicht, dass das Kernteil 167 mit seinem Außendurchmesser ohne am Umfang Magnetfluss hindernden Luftspalt einzusetzen. Der Wirkungsgrad des elektrischen Antriebs 16 steigt, so dass für den Betrieb weniger Energie aufgewendet werden muss und/oder Material eingespart werden kann. Gleiches gilt für die Passzone 305 und das Kernteil 167.
Das Gehäuse 156 weist eine rohrartige Innenwand auf und ist zwischen je einem Zentrum einer Wicklung 162, 165 mehrfach abgestuft ist.The fitting zone 302 makes it possible for the core part 167 with its outer diameter to be used without an air gap preventing the circumference of magnetic flux. The efficiency of the electric drive 16 increases, so that less energy has to be used for the operation and / or material can be saved. The same applies to the pass zone 305 and the core part 167.
The housing 156 has a tubular inner wall and is stepped several times between each center of a winding 162, 165.

In Figur 5 ist ein allgemein topfförmiges Einpresswerkzeug 320 aus Stahl dargestellt. Dieses Einpresswerkzeug 320 dient dazu, den in Figur 3 dargestellten Aufbau in das in Figur 4 dargestellte Gehäuse 156 einzusetzen. Von einem Boden 321 geht eine Ringwand 322 aus, die mit einer schmalen bzw. schmaleren Drückringwand 323 endet. Eine Stirnfläche 324 dient dazu, auf einen schmalen Ringbereich 325 (Figur 3) Druck bzw. eine Druckkraft auf das Kernteil 168 ausüben zu können. Mit ihrem Innendurchmesser übergreift die Drückringwand 323 die Wicklung 254. Beim Einschieben des Aufbaus aus Figur 3 befindet sich die Drückringwand 323 zwischen dem Gehäuse 156 - bzw. dem Abschnitt 296 - und der Wicklung 165. Zwei Löcher (Sacklöcher) 326 und 329 sind in einen ringfömigen, deckelnahen Bereich 333 eingebracht und nehmen im Zustand der Montage die zwei elektrischen Anschlüsse 257 und 260 auf. Beim Einsetzen übergreift ein Einpresswerkzeug 320 mit einer Drückringwand 323 die elektrische Wicklung 165 übergreift und überträgt bei einer Einsetzbewegung eine Druckkraft auf das Kernteil 168 überträgt.In Figure 5 A generally cup-shaped press tool 320 made of steel is shown. This press tool 320 serves to Figure 3 structure shown in the in Figure 4 insert housing 156 shown. A ring wall 322 extends from a bottom 321 and ends with a narrower or narrower push ring wall 323. An end face 324 serves to fit onto a narrow ring area 325 ( Figure 3 ) To be able to exert pressure or a compressive force on the core part 168. With its inner diameter, the push ring wall 323 overlaps the winding 254. When the structure is pushed in Figure 3 there is the push ring wall 323 between the housing 156 - or the section 296 - and the winding 165. Two holes (blind holes) 326 and 329 are introduced into a ring-shaped region 333 near the cover and take the two electrical connections 257 and 260 on. When inserting, a press tool 320 with a push ring wall 323 overlaps the electrical winding 165 and transmits a compressive force to the core part 168 during an insertion movement.

Nach dem der Aufbau aus Figur 3 in das Gehäuse 156 aus Figur 4 eingesetzt ist, Figur 6, wird eine Vormontageeinheit aus verschiedenen Bauteilen in die Gleithülse 242 eingesetzt. Diese Vormontageeinheit weist folgende Bauteile auf: den Rückschlusskern 183, in dessen gestufte Öffnung ein Kontaktlager 340 eingesetzt ist. Auf einem Absatz des Kontaktlagers 340 sitzt eine Kontaktbrücke 343, die zwischen einem Bund 346 eines Kopfes 349 der Schaltachse 269 und dem Kontaktlager 340 angeordnet ist. Zwischen dem Kopf 349 und der Kontaktbrücke 343 ist eine Unterlegscheibe 352 angeordnet. Während sich eine Außenseite des Kontaktlagers 340 in der Öffnung abstützt, sitzt in dessen von der Kontaktbrücke 343 abgewandten Seite eine Druckfeder 355, die sich an einer Stirnfläche eines Hülsenteils 358 abstützt. Das Hülsenteil 358 wird mittels eines Innenvorsprungs 361 in einer Ringnut 364 gehalten. Um das Hülsenteil 358 erstreckt sich eine weitere Druckfeder 367, die sich an einer Stirnfläche einer Vertiefung im Hubmittel 189 abstützt. Die Druckfeder 367 stützt sich mit ihrem anderen Ende am einstückig angeformten Ansatz 186 des Rückschlusskerns 183 ab. Die Schaltachse 269 ist in einem rohrförmigen Stutzen 370 des Hubmittels 189 befestigt. Der Rückschlusskern 183 weist auf der zur Kontaktbrücke 343 gerichteten Seite eine oder mehrere Vertiefungen 371 auf. In diese Vertiefungen 371 können durchgebogene Enden der Kontaktbrücke 343 eintauchen.After the build out Figure 3 into the housing 156 Figure 4 is used Figure 6 , a pre-assembly unit made of various components is inserted into the sliding sleeve 242. This preassembly unit has the following components: the yoke core 183, in the stepped opening of which a contact bearing 340 is inserted. A contact bridge 343 sits on a shoulder of the contact bearing 340 and is arranged between a collar 346 of a head 349 of the switching axis 269 and the contact bearing 340. A washer 352 is arranged between the head 349 and the contact bridge 343. While an outer side of the contact bearing 340 is supported in the opening, a compression spring 355 is seated in its side facing away from the contact bridge 343 and is supported on an end face of a sleeve part 358. The sleeve part 358 is held in an annular groove 364 by means of an inner projection 361. A further compression spring 367 extends around the sleeve part 358 and is supported on an end face of a depression in the lifting means 189. The other end of the compression spring 367 is supported on the integrally molded projection 186 of the yoke core 183. The switching axis 269 is fastened in a tubular connecting piece 370 of the lifting means 189. The yoke core 183 has one or more depressions 371 on the side facing the contact bridge 343. Bent ends of the contact bridge 343 can dip into these depressions 371.

Diese Vormontageeinheit wird in die Gleithülse 242, voran mit dem rohrförmigen Stutzen 370 des Hubmittels 189, eingesetzt. Der Rückschlusskern 183 wird mit seinem radial äußersten Rand an die Stirnfläche 290 des Absatzes 293 angelegt.This preassembly unit is inserted into the sliding sleeve 242, first with the tubular connecting piece 370 of the lifting means 189. The yoke core 183 is applied with its radially outermost edge to the end face 290 of the shoulder 293.

Es ist Verfahren zur Montage eines elektrischen Antriebs 16 mit einem rohrartigen Gehäuse 156 mit einer Schubeinrichtung 160 und einer Schalteinrichtung 161 offenbart, wobei zunächst ein Wicklungsträger 216 mit einer elektrischen Wicklung 162 eingesetzt wird, dann ein erstes und ein zweites elektromagnetisch erregbares Kernteil 167, 168 und danach ein weiterer Wicklungsträger 245 mit zumindest einer elektrischen Wicklung 165 eingesetzt wird. Es ist des Weiteren vorgesehen, dass nach dem ersten elektromagnetischen Kernteil 167 und vor dem zweiten elektromagnetischen Kernteil 168 ein elektromagnetisch nicht erregbares Zwischenteil 166 in das Gehäuse eingesetzt wird.A method for assembling an electric drive 16 with a tubular housing 156 with a pushing device 160 and a switching device 161 is disclosed, wherein first a winding support 216 with an electrical winding 162 is used, then a first and a second electromagnetically excitable core part 167, 168 and then another winding carrier 245 with at least one electrical winding 165 is used. It is further provided that an intermediate part 166, which cannot be excited electromagnetically, is inserted into the housing after the first electromagnetic core part 167 and before the second electromagnetic core part 168.

Danach wird eine weitere Vormontagegruppe auf den Rückschlusskern 183 aufgesetzt: Diese Vormontagegruppe weist als Träger den Deckel 153 auf. In diesen Deckel sind der Bolzen 150 und der Bolzen 152 eingesetzt. Deren Köpfe 380 und 383 bilden beispielsweise mit kupfernen Einlagen die Gegenkontakte, die durch die Kontaktbrücke 343 miteinander elektrisch zu verbinden sind. Weitere Teil dieser Vormontagegruppe sind die hindurchragenden Kontakte (Flachstecker) 263 und 266. Anschließend wird der Bördelrand 275 nach radial innen auf den Bördelabsatz 284 umgelegt und so der Deckel 153 mit dem Gehäuse 156 befestigt. Anschließend wird eine Druckfeder 390 - eingesetzt in eine Vertiefung 393 um einen Stift 396 mit dem Hubmittel 176 in die Gleithülse 213 gesetzt.A further preassembly group is then placed on the yoke core 183: this preassembly group has the cover 153 as a carrier. The bolt 150 and the bolt 152 are inserted into this cover. Their heads 380 and 383 form, for example with copper inserts, the counter-contacts which are to be electrically connected to one another by the contact bridge 343. Another part of this preassembly group are the protruding contacts (tabs) 263 and 266. The flanged edge 275 is then folded radially inward onto the flanged shoulder 284 and the cover 153 is thus fastened to the housing 156. A compression spring 390 is then inserted into a recess 393 around a pin 396 with the lifting means 176 in the sliding sleeve 213.

Im Betrieb wird zunächst die Wicklung 162 bestromt, damit das Andrehritzel 22 vorgespurt wird. Danach wird die Wicklung 165 bestromt, um die Kontaktbrücke 343 gegen die beiden Köpfe 380 und 383 der Bolzen 150 und Bolzen 152 zu drücken und so eine elektrische Verbindung zwischen der Starterbatterie und dem Startermotor 13 herzustellen. Der Startermotor wird dann bestromt und dadurch das Andrehritzel 22 gedreht. Vorspuren des Andrehritzels 22 und Schalten der Kontaktbrücke 343 sind damit vollständig entkoppelt. Gemäß diesem Ausführungsbeispiel ist vorgesehen, die Wicklung 165 nur als Einzugswicklung zu verwenden und demnach mit der Wicklung 254 und deren bewirkten elektromagnetischen Feld das Hubmittel 189 im vorgerückten Zustand zu halten. Die Wicklung 165 wird folglich nach dem Vorrücken ausgeschaltet.During operation, the winding 162 is first energized so that the starter pinion 22 is pre-energized. The winding 165 is then energized in order to press the contact bridge 343 against the two heads 380 and 383 of the bolts 150 and bolts 152 and thus establish an electrical connection between the starter battery and the starter motor 13. The starter motor is then energized and the starter pinion 22 is thereby rotated. Toe-in of the starter pinion 22 and switching of the contact bridge 343 are thus completely decoupled. According to this exemplary embodiment, it is provided that the winding 165 is used only as a pull-in winding and accordingly with the winding 254 and the electromagnetic field caused to keep the lifting means 189 in the advanced state. The winding 165 is consequently switched off after the advance.

Alternativ kann vorgesehen sein, dass nur eine Wicklung 162 und eine Wicklung 165 vorhanden sind, wobei die Wicklung 165 sowohl das VorrĂĽcken als auch das Halten des Hubmittels 189 bewirkt.Alternatively, it can be provided that only one winding 162 and one winding 165 are present, the winding 165 causing both the advancement and the holding of the lifting means 189.

Es ist vorgesehen, dass die Schubeinrichtung 160 und die Schalteinrichtung 161 mittels je eines elektromagnetischen Kreises 178, 210, vorzugsweise separat, zu bewegen sind.It is provided that the pushing device 160 and the switching device 161 can each be moved, preferably separately, by means of an electromagnetic circuit 178, 210.

Es ist somit ein elektrischer Antrieb 16 vorgesehen, bei dem der elektromagnetische Kreis 210 der Schalteinrichtung 161 eine elektrische Wicklung 165 aufweist, die dazu dient, das Hubmittel 189 der Schalteinrichtung 161 in Richtung einer Achse 272 zu einem RĂĽckschlusskern 183 zu schieben, wobei der elektromagnetische Kreis 179 der Schubeinrichtung 160 eine elektrische Wicklung 162 aufweist, die mit einer Wicklung 254 derart elektrisch verbunden ist, dass der elektromagnetische Kreis 210 der Schalteinrichtung 161 durch Bestromen der Wicklung 162 erregbar ist.An electric drive 16 is thus provided, in which the electromagnetic circuit 210 of the switching device 161 has an electrical winding 165 which serves to push the lifting means 189 of the switching device 161 in the direction of an axis 272 to a return core 183, the electromagnetic circuit 179 of the pushing device 160 has an electrical winding 162 which is electrically connected to a winding 254 in such a way that the electromagnetic circuit 210 of the switching device 161 can be excited by energizing the winding 162.

Das Hubmittel 176 des elektromagnetischen Kreises 179 der Schubeinrichtung 160 hat ein Anlenkteil 187 hat, mit dem Zugkräfte bewirkt werden.The lifting means 176 of the electromagnetic circuit 179 of the thrust device 160 has an articulation part 187 with which tensile forces are brought about.

Es ist vorgesehen, zunächst die Wicklung 165 zu wickeln und danach die Wicklung 162 und dann die Wicklung 254. Alternativ, d. h. für den Fall, dass die Wicklung 165 auf der Wicklung 254 angeordnet sein soll, ist zunächst die Wicklung 254, dann die Wicklung 162 und danach die Wicklung 165 zu wickeln.It is envisaged to first wind winding 165 and then winding 162 and then winding 254. Alternatively, i. H. in the event that the winding 165 is to be arranged on the winding 254, the winding 254 must first be wound, then the winding 162 and then the winding 165.

Die Wicklung 162 und die Wicklung 254 können auch einstückig ausgeführt werden.The winding 162 and the winding 254 can also be made in one piece.
