HINTERGRUND DER ERFINDUNGBACKGROUND OF THE INVENTION
Fig. 1 zeigten Drehmomentwandler 10 nach dem Stand der Technik mit drei in den Drehmomentwandler 10 führenden hydraulischen Kanälen. Der Drehmomentwandler 10 beinhaltet einen Wandlerdeckel 4 und einen mit dem Deckel 4 verbundenen Zapfen; der das Drehmoment vom Motor aufnimmt. Der Deckel 4 schließt eine Turbine 46, die gegenüber dem Deckel 4 drehbar ist, und einen zwischen einem Laufrad 40 und der Turbine 46 angeordneten Stator 44 ein. Der Deckel 4 weist eine röhrenförmige Laufradnabe 16 auf. Die Laufradnabe 16 befindet sich in einem Abstand von einer Statorwelle 8, die mit dem Stator 44 verzahnt ist. Die Turbine 46 ist nichtdrehbar mit einer Turbinennabe 20 und die Turbinennabe 20 über einen Dämpfer 38 und eine Dämpfernabe 62 mit einer Antriebswelle 14 verbunden. Wenn der Dämpfer 38 zusammengedrückt wird, kommt es zu einer Relativbewegung zwischen der Turbinennabe 20 und der Dämpfernabe 62. Der Drehmomentwandler 10 beinhaltet auch einen Kupplungskolben 30 und Kupplungslamellen 6. Eine Kupplungslamelle 6 ist durch Blattfedern 64 drehbar mit einer angeschweißten Platte 48 und eine andere Kupplungslamelle 6 drehbar mit dem Deckel 4 verbunden. Die drei in den Drehmomentwandler 10 führenden Kanäle befinden sich: zwischen der Laufradnabe 16 und der Statorwelle 8; zwischen der Statorwelle 8 und der Antriebswelle 14, und als Bohrung innerhalb der Antriebswelle 14.FIG. 1 shows prior art torque converters 10 with three hydraulic passages leading into torque converter 10. The torque converter 10 includes a converter cover 4 and a pin connected to the cover 4; which absorbs the torque from the engine. The lid 4 includes a turbine 46 rotatable relative to the lid 4 and a stator 44 disposed between an impeller 40 and the turbine 46. The lid 4 has a tubular impeller hub 16. The impeller hub 16 is located at a distance from a stator shaft 8, which is toothed with the stator 44. The turbine 46 is non-rotatably connected to a turbine hub 20 and the turbine hub 20 is connected to a drive shaft 14 via a damper 38 and a damper hub 62. When the damper 38 is compressed, there is relative movement between the turbine hub 20 and the damper hub 62. The torque converter 10 also includes a clutch piston 30 and clutch plates 6. A clutch plate 6 is rotatable by leaf springs 64 having a welded plate 48 and another clutch plate 6 rotatably connected to the lid 4. The three leading into the torque converter 10 channels are: between the impeller hub 16 and the stator shaft 8; between the stator shaft 8 and the drive shaft 14, and as a bore within the drive shaft 14th
Die Vorteile nach dem aktuellen Stand der Technik bestehen in der Fähigkeit der Kanäle zum Steuern von drei Drücken innerhalb des Drehmomentwandlers 10, um Kupplungen einzukuppeln, auszukuppeln und zu kühlen. Die Nachteile dieser Kupplung besteht jedoch in der komplexen Konstruktion mit den drei Kanälen.The advantages of the current state of the art are the ability of the channels to control three pressures within the torque converter 10 to engage, disengage, and cool clutches. The disadvantages of this coupling, however, is the complex construction with the three channels.
Die drei hydraulischen Kanäle des Drehmomentwandlers 10 ermöglichen die Bildung einer abgeschlossenen Kolbenkammer 12, welche das Einkuppeln der Wandlerkupplung 60 ermöglicht. Der Kolben 30 ist üblicherweise vom Wandlerdeckel 4 und von der Antriebswelle 14 umschlossen. Der Kolben 30 drückt die Kupplung 60 gegen die Turbine 46, die für die Wandlerkupplung 60 einen axialen Anschlag benötigt. Die angeschweißte Platte 48 besteht aus dickem Stahlblech und ist am Deckel 4 des Drehmomentwandlers 10 angeschweißt.The three hydraulic passages of the torque converter 10 allow the formation of a sealed piston chamber 12 which allows the clutch 60 to be engaged. The piston 30 is usually from the converter cover 4 and of the Drive shaft 14 enclosed. The piston 30 urges the clutch 60 against the turbine 46, which requires an axial stop for the converter clutch 60. The welded plate 48 is made of thick steel sheet and is welded to the cover 4 of the torque converter 10.

Zu den Vorteilen der vorliegenden Erfindung gehören eine geringere Komplexität der Konstruktion der drei Kanäle durch einen abgedichteten Kolben, einen Turbinendämpfer und eine Kupplung mit hoher Schlupfkapazität. Durch die konstruktive Gestaltung kann auf das Anschweißen der Kupplungslamelle im Innern des Deckels verzichtet und eine Einsparung an Material und/oder der Anzahl der Teile erreicht werden.Advantages of the present invention include less complexity of construction of the three channels by a sealed piston, a turbine damper, and a high slip capacity clutch. Due to the structural design can be dispensed with the welding of the clutch plate inside the lid and a saving of material and / or the number of parts can be achieved.
Fig. 3 zeigt eine weitere Ausführungsart der vorliegenden Erfindung. Fig. 3 zeigt ähnlich wie Fig. 2 einen Querschnitt durch einen hydraulischen Drehmomentwandler 200. Der Drehmomentwandler 200 weist einen Deckel 204 auf, der mit einem Zapfen 202 verbunden ist. Der Deckel 204 weist einen Dichtsitz 250 auf. Im Innern des Deckels 204 befinden sich ein Laufrad 240, eine Turbine 246 mit einem Turbinengehäuse 248 und ein Stator 244. Die Laufradnabe 216 befindet sich in einem Abstand von einer Statorwelle 208 und einer Antriebswelle 214. Eine Turbinennabe 220 ist fest mit dem Gehäuse 248 vernietet, um eine flüssigkeitsdichte Abdichtung zu erzeugen. Das Turbinengehäuse 220 ist durch eine Dichtung 218 gegen die Statorwelle 208 abgedichtet und erzeugt so eine Druckkammer 212.Fig. 3 shows another embodiment of the present invention. Similar to FIG. 2, FIG. 3 shows a cross section through a hydraulic torque converter 200. The torque converter 200 has a cover 204 which is connected to a journal 202. The lid 204 has a sealing seat 250. Inside the lid 204 are an impeller 240, a turbine 246 with a turbine housing 248 and a stator 244. The impeller hub 216 is spaced from a stator shaft 208 and a drive shaft 214. A turbine hub 220 is fixedly secured to the housing 248 to create a liquid-tight seal. The turbine housing 220 is sealed by a seal 218 against the stator shaft 208, thus creating a pressure chamber 212.
Der Drehmomentwandler 200 beinhaltet auch eine Wandlerkupplung 260 mit einem Kolben 230, Kupplungslamellen 206 und einem Dämpfer 238. Der Kolben 230 ist durch eine Dichtung 232 gegen die Blattfeder-Mitnehmerscheibe abgedichtet. Die Turbinennabe 220 ist durch eine Dichtung 222 gegen die Blattfeder-Mitnehmerscheibe abgedichtet.The torque converter 200 also includes a converter clutch 260 having a piston 230, clutch plates 206 and a damper 238. The piston 230 is sealed by a seal 232 against the leaf spring driver disk. The turbine hub 220 is sealed by a seal 222 against the leaf spring driver disk.
Das Motordrehmoment gelangt über den Zapfen 202 in den Drehmomentwandler 200. Das Drehmoment wird vom Zapfen 202 zum Deckel 204 übertragen. Vom Deckel 204 kann das Drehmoment zum Laufrad 240 und zur Blattfeder-Mitnehmerscheibe 210 übertragen werden. Die Kühlflüssigkeit tritt durch den Betätigungskanal 209 zwischen der Statorwelle 208 und der Antriebswelle 214 ein. Die Kühlflüssigkeit gelangt durch ein quer durchgebohrtes Loch 252 in eine Kammer 256. Die Kühlflüssigkeit tritt zwischen der Statorwelle 208 und der Laufradnabe 216 wieder aus. Zum Betätigen der Kupplung 260 fließt die Betätigungsflüssigkeit durch das Innere der Antriebswelle 214. Der Druck wird durch ein quer durchgebohrtes Loch im Dichtsitz 250 in die Druckkammer 212 geleitet. Das quer durchgebohrte Loch 254 liegt in einer anderen Rotationsebene als das quer durchgebohrte Loch 252. The engine torque passes through the pin 202 in the torque converter 200. The torque is transmitted from the pin 202 to the cover 204. From the cover 204, the torque can be transmitted to the impeller 240 and to the leaf spring driver disk 210. The cooling liquid enters through the actuating passage 209 between the stator shaft 208 and the drive shaft 214. The coolant passes through a through-drilled hole 252 in a chamber 256. The coolant exits between the stator shaft 208 and the impeller hub 216 again. To actuate the clutch 260, the actuating fluid flows through the interior of the drive shaft 214. The pressure is passed through a transversely drilled hole in the sealing seat 250 in the pressure chamber 212. The drilled through hole 254 lies in a different plane of rotation than the transversely drilled hole 252.
