Antriebslagerschild 19 ab, und der Kommutatorlagerdeckel 70 am Polrohr 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 drei Planetenräder 86, die mittels Wälzlager 89 auf Achszapfen 92 abgestützt sind. Die Planetenräder 86 wälzen in einem Hohlrad 95 ab, das im Polrohr 28 außenseitig gelagert ist. In Richtung zur Abtriebsseite schließt sich an die Planetenräder 86 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 Drive end plate 19 from, and the Kommutatorlagerdeckel 70 on the pole tube 28th In the drive direction, a so-called sun gear 80 connects to the armature 37, which is part of a planetary gear 83. The sun gear 80 is surrounded by a plurality of planet wheels 86, usually three planet wheels 86, which are supported by means of roller bearings 89 on journals 92. The planet gears 86 roll in a ring gear 95, which is mounted outside in the pole tube 28. Towards the output side, the planet wheels 86 are adjoined by a planetary carrier 98, in which the axle journals 92 are accommodated. The planet carrier 98 is in turn stored in an intermediate storage 101 and a slide bearing 104 arranged therein. The intermediate bearing 101 is designed cup-shaped, that in this both the planet carrier 98, and the planet wheels 86th
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 44 einen weiteren Wellenzapfen 110 auf, der ebenfalls in einem Gleitlager 113 aufgenommen ist, ab.

Furthermore, the ring gear 95 is arranged in the cup-shaped intermediate bearing 101, which is ultimately closed by a cover 107 relative to the armature 37. Also, the intermediate bearing 101 is supported with its outer circumference on the inside of the pole tube 28. The armature 37 has on the end facing away from the commutator 52 end of the drive shaft 44 has a further shaft journal 110, which is also received in a sliding bearing 113, from. The sliding bearing 113 in turn is in a central bore of the
Planetenträgers 98 aufgenommen. Der Planetenträger 98 ist einstückig mit der Abtriebswelle 116 verbunden. Diese Abtriebswelle 116 ist mit ihrem vom Planet carrier 98 recorded. The planetary carrier 98 is integrally connected to the output shaft 116. This output shaft 116 is connected to her from

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 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 Intermediate bearing 101 facing away from the end 119 in a further bearing 122 which is fixed in the drive bearing plate 19, supported.

This shaft-hub connection 128 in this case allows the axially rectilinear sliding of a driver 131. This driver 131 is a sleeve-like extension which is integral with a cup-shaped outer ring 132 of the freewheel 137. This freewheel 137 (Richtgesperre) further consists of the inner ring 140 which is disposed radially within the outer ring 132. Between the inner ring 140 and the outer ring 132 clamping body 138 are arranged. These clamp body 138 prevent 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 Relativbewegung zwischen Innenring 140 und Außenring 132 nur in eine Richtung. In diesem Cooperation with the inner and outer ring relative rotation between the outer ring and the inner ring in a second direction. In other words, the freewheel 137 allows a relative movement between inner ring 140 and outer ring 132 in one direction only. In this
Ausführungsbeispiel ist der Innenring 140 einstückig mit dem Andrehritzel 22 und dessen Schrägverzahnung 143 (Außenschrägverzahnung) ausgeführt. Der Vollständigkeit halber sei hier noch auf den Einspurmechanismus Embodiment, the inner ring 140 is formed integrally with the starter pinion 22 and the helical teeth 143 (external helical teeth). For the sake of completeness, here is still the Einspurmechanismus
eingegangen. Das Eindrückrelais 16 weist einen Bolzen 150 auf, der ein received. The push-in relay 16 has a bolt 150, the one
elektrischer Kontakt ist und der an den Pluspol einer elektrischen Starterbatterie, die hier nicht dargestellt ist, angeschlossen ist. Dieser Bolzen 150 ist durch einen Relaisdeckel 153 hindurchgeführt. Dieser Relaisdeckel 153 schließt ein electrical contact and is connected to the positive pole of an electric starter battery, which is not shown here. This bolt 150 is passed through a relay cover 153. This relay cover 153 includes
Relaisgehäuse 156 ab, das mittels mehrerer Befestigungselemente 159 Relay housing 156 from, by means of several fasteners 159
(Schrauben) am Antriebslagerschild 19 befestigt ist. Im Relais 16 ist weiterhin eine Einzugswicklung 162 und eine sogenannte Haltewicklung 165 angeordnet. Die Einzugswicklung 162 und die Haltewicklung 165 bewirken beide jeweils im eingeschalteten Zustand ein elektromagnetisches Feld, welches sowohl das (Screws) is attached to the drive end plate 19. In relay 16, a pull-in winding 162 and a so-called holding coil 165 is further arranged. The pull-in winding 162 and the holding winding 165 each cause an electromagnetic field in the switched-on state, which both the
Relaisgehäuse 156 (aus elektromagnetisch leitfähigem Material), einen linear beweglichen Anker 168 und einen Ankerrückschluss 171 durchströmt. Der Anker 168 trägt eine Schubstange 174, die beim linearen Einzug des Ankers 168 in Richtung zu einem Schaltbolzen 177 bewegt wird. Mit dieser Bewegung der Relay housing 156 (made of electromagnetically conductive material), a linearly movable armature 168 and an armature circuit 171 flows through. The armature 168 carries a push rod 174, which is moved in the direction of linear retraction of the armature 168 in the direction of a switching pin 177. With this movement of
Schubstange 174 zum Schaltbolzen 177 wird dieser aus seiner Ruhelage in Push rod 174 to the shift pin 177 this is from its rest position in
Richtung zu zwei Kontakten 180 und 181 bewegt, so dass eine am zu den Direction to two contacts 180 and 181 moves, so that one on the
Kontakten 180 und 181 Ende des Schaltbolzens 177 angebrachte Kontaktbrücke 184 beide Kontakte 180 und 181 elektrisch miteinander verbindet. Dadurch wird vom Bolzen 150 elektrische Leistung über die Kontaktbrücke 184 hinweg zur Stromzuführung 61 und damit zu den Kohlebürsten 58 geführt. Der Startermotor 13 wird dabei bestromt. Contacts 180 and 181 end of the switching pin 177 mounted contact bridge 184 connects both contacts 180 and 181 electrically. As a result, electrical power is conducted from the bolt 150 across the contact bridge 184 to the power supply 61 and thus to the carbon brushes 58. The starter motor 13 is energized.
Das Relais 16 bzw. der Anker 168 hat aber darüber hinaus auch die Aufgabe, mit einem Zugelement 187 einen dem Antriebslagerschild 19 drehbeweglich However, the relay 16 or the armature 168 also has the task of a traction element 187 a drive bearing plate 19 rotatably
angeordneten Hebel zu bewegen. Dieser Hebel 190, üblicherweise als to move arranged lever. This lever 190, commonly called
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. Running fork lever, engages with two "tines" not shown here on its outer circumference two discs 193 and 194 to move a clamped between these driver ring 197 for freewheel 137 back against the resistance of the spring 200 and thereby einzura the starter pinion 22 in the ring gear 25 ,
Für die hier beschriebene Erfindung ist die Ausführung des Andrehritzels 22 mit Schrägverzahnung und die Ausführung der Welle-Nabe-Verbindung 128 mit For the invention described here, the embodiment of the Andrehritzels 22 with helical teeth and the execution of the shaft-hub connection 128 with
Geradverzahnung nicht von Bedeutung. Stattdessen kann das Andrehritzel 22 auch geradverzahnt und die Welle-Nabe-Verbindung 128 mit üblichem nicht selbst hemmendem Steilgewinde ausgeführt sein. Spur gearing does not matter. Instead, the starter pinion 22 may also be straight-toothed and the shaft-hub connection 128 may be designed with conventional non-self-locking helical thread.
Figur 2a zeigt eine Ansicht der Startvorrichtung 10 von der Anschlussseite des Relais 16 aus gesehen mit einem ersten Ausführungsbeispiel des Dämmmantels 203. In diesem Ausführungsbeispiel besteht der Dämmmantel 203 aus einem aus den FIG. 2 a shows a view of the starting device 10 as seen from the connection side of the relay 16 with a first exemplary embodiment of the damping jacket 203 In this embodiment, the Dämmmantel 203 consists of a from the
Außenumfang 206 aufgebrachten Schlauch 209, der hier zumindest aus einem Outer perimeter 206 applied hose 209, here at least one
Kunststoff (Grundbestandteile sind synthetisch oder halbsynthetisch erzeugte Polymere mit organischen Gruppen) besteht. Dieser Schlauch 209 kann beispielsweise aus einem Elastomer (Gummi etc.) oder einem elastischen Thermoplast wie Polyethylen, Polyurethan bestehen. Bevorzugt ist dieser Schlauch 209 als offene oder geschlossene Poren 212 aufweisender Kunststoff ausgebildet. Dieser Schlauch 209 kann Plastic (basic components are synthetic or semi-synthetic polymers with organic groups) exists. This hose 209 may for example consist of an elastomer (rubber, etc.) or an elastic thermoplastic such as polyethylene, polyurethane. Preferably, this hose 209 is formed as plastic having open or closed pores 212. This hose 209 can
beispielsweise auf seiner Außenseite 215 mit einer Metallfolie 218 kaschiert sein (Figur 2b), um Strahlungswärme fernzuhalten und so die Lebensdauer des Schlauchs 109 zu erhöhen. Der Schlauch 209 kann somit aus Poren 212 aufweisendem Material sein. For example, be laminated on its outer side 215 with a metal foil 218 (Figure 2b) to keep away radiant heat and thus increase the life of the hose 109. The tube 209 may thus be made of pores 212 having material.
Figur 3 zeigt einen Längsschnitt durch das mit dem Schlauch 209 (Figur 2a) bestückte Relais 16. Der Schlauch 209 sitzt um einen zylindrischen Abschnitt 221 des Relais 16 und umgreift in diesem Fall sogar eine zum Antriebslagerschild 19 gerichtete Schräge bzw. Fase 224. In Richtung zum Relaisdeckel 153 umgreift der Schlauch 209 einen Bördelrand 227, mit dem der Relaisdeckel 153 am Relaisgehäuse 156 befestigt ist. FIG. 3 shows a longitudinal section through the relay 16 fitted with the hose 209 (FIG. 2a). The hose 209 sits around a cylindrical section 221 of the relay 16 and in this case even encompasses a bevel 224 directed toward the drive end shield 19 To the relay cover 153, the hose 209 surrounds a beaded edge 227, with which the relay cover 153 is attached to the relay housing 156.
In Figur 4 ist ausschnittweise ein weiteres Ausführungsbeispiel eines Dämmmantels 203 gezeigt. Hier ist zwischen dem Schlauch 209 und dem Relais 16 eine zusätzliche Dämmschicht 230 angeordnet. In diesem Ausführungsbeispiel weist hauptsächlich die Dämmschicht 230 schalldämmende Eigenschaften auf, während der drumherum angeordnete Schlauch 209 aus Kunststoff eher als Haltemittel fungiert, allerdings auch schalldämmende Eigenschaften hat. Bei einem derartigen Verbund kann ebenfalls eine Metallfolie 218 als abschirmende Schicht auf dem Schlauch 209 angebracht sein. Zwischen dem Schlauch 209 und dem Relaisgehäuse 156 kann eine Dämmschicht 230 mit vorzugsweise Poren 212 aufweisendem oder faserhaltigem Material angeordnet sein. In Figure 4, a further embodiment of a Dämmmantels 203 is shown in sections. Here, an additional insulation layer 230 is disposed between the tube 209 and the relay 16. In this embodiment, mainly the insulating layer 230 has sound insulating properties, while the surrounding tube 209 made of plastic rather acts as a holding means, but also has sound insulating properties. In such a composite also a metal foil 218 may be mounted as a shielding layer on the tube 209. Between the tube 209 and the relay housing 156, an insulating layer 230 may be arranged with preferably pores 212 having or fibrous material.
