For this purpose, the device has a control and regulation unit 38 coupled to the blocking unit 24a, with a computer unit 96 and a memory unit 98, an operating program being stored in the memory unit 98.
Die Sperreinheit 24a weist ein mit einem Schwungrad 26 gekop¬ peltes, von einem drehfest mit dem Schwungrad 26 verbundenen Zahnkranz gebildetes Sperrmittel 28 auf. Das Sperrmittel 28 dient ferner zur Sperrung der ersten Motoreinheit 14 beim Ab¬ stellen des Kraftfahrzeugs bzw. ist ein Teil einer Parksperr- einheit. Die Sperreinheit 24a umfasst ferner einen elektromagnetischen Aktuator 100a mit einer Spule 102a und einem mittels der Spule 102a betätigbaren Stößel 104a.

Figur 2 zeigt ein Balkendiagramm zur Darstellung der Funktion der Planetengetriebeeinheit 10 in einem Vorwärtsfahrmodus . Für die von einem Elektromotor gebildete Motoreinheit 22 ist eine vertikale Gerade n22? für die von einer Brennkraftmaschine gebildete erste Motoreinheit 14 ist eine vertikale Ge- rade ni4, für die Welle 50 ist eine vertikale Gerade n50, für die Abtriebswelle 88 ist eine vertikale Gerade n88, für die zweite Bremseinheit 84 ist eine vertikale Gerade n84 und für die von einem Elektromotor gebildete Motoreinheit 20 ist eine vertikale Gerade n2o aufgetragen, wobei sich Abstände der Geraden n14, n2o> n22, nso, n84, n88 aus vorliegenden Zahnradverhältnissen ergeben. Um Drehzahlen darzustellen, werden bekannte Drehzahlen mit Balken n40, n44 verbunden, wobei der Balken n4o die Drehzahlen des ersten Planetensatzes 40 und der Balken n44 die Drehzahlen des dritten Planetensatzes 44 darstellt. Die zweite Bremseinheit 84 ist geschlossen, so dass ein Schnittpunkt des Balkens n44 mit der Geraden ne4 bei Null liegt.FIG. 2 is a bar graph illustrating the function of the planetary gear unit 10 in a forward drive mode. For the motor unit 22 formed by an electric motor is a vertical straight n 22? for the first motor unit 14 formed by an internal combustion engine, a vertical rade ni 4 , for the shaft 50 is a vertical line n 50 , for the output shaft 88 is a vertical line n 88 , for the second brake unit 84 is a vertical line n 84 and for the motor unit 20 formed by an electric motor is a vertical straight line n 2 o, resulting in distances of the straight lines n 14 , n 2 o > n 22 , nso, n 84 , n 88 from present gear ratios. To represent speeds, known speeds are connected to bar n 40 , n 44 , wherein the bar n 4 o the speeds of the first planetary gear set 40 and the bar n 44 represents the rotational speeds of the third planetary gear set 44. The second brake unit 84 is closed, so that an intersection of the bar n 44 with the straight line ne 4 is zero.
Im dargestellten Vorwärtsfahrmodus liefert die erste Motor- einheit 14 ein Drehmoment Mi4, welches als auf den Balken n40 vertikal nach oben wirkende Kraft dargestellt werden kann. Ein Abtriebsdrehmoment M88 lässt sich als auf den Balken n44 nach unten wirkende Last darstellen. Das Abtriebsdrehmoment M88 wirkt mit einem Drehmoment M74 bzw. mit einer in einem Schnittpunkt der Balken n4o, n44 auf den Balken n40. Um ein Gleichgewicht zu erreichen, wird die Motoreinheit 20 als Generator betrieben und wirkt mit einem Drehmoment M2o bzw. mit einer Last an einem dem Schnittpunkt gegenüberliegenden Ende des Balkens n40 nach unten. Eine aus dem Generatorbetrieb der Motoreinheit 20 resultierende Energie wird der Motoreinheit 22 zugeführt und in ein Drehmoment M22 umgewandelt, das auf den Balken n40 im Schnittpunkt nach oben wirkt und eine Unterstützung desselben bewirkt.In the illustrated forward drive mode, the first motor unit 14 supplies a torque M i4 , which can be represented as a force acting vertically upward on the bar n 40 . An output torque M 88 can be represented as a load acting down on the bar n 44 . The output torque M 88 acts with a torque M 74 or at an intersection of the bar n 4 o, n 44 on the bar n 40th In order to achieve equilibrium, the motor unit 20 is operated as a generator and acts with a torque M 2 o or with a load at an intersection of the opposite end of the bar n 40 down. An energy resulting from the generator operation of the motor unit 20 is supplied to the motor unit 22 and converted into a torque M 22 , which acts on the bar n 40 at the intersection point and causes support thereof.
Neben dem dargestellten Vorwärtsfahrmodus sind zahlreiche weitere Modi denkbar. Figur 3 zeigt ein Balkendiagramm zur Darstellung der Funktion der Planetengetriebeeinheit 10 in einem Rückwärtsfahrmodus . Wie an einem Balken n44' zu erkennen ist, weist die Abtriebswelle 88 eine negative Drehzahl auf.In addition to the forward drive mode shown, numerous other modes are conceivable. FIG. 3 is a bar graph illustrating the function of the planetary gear unit 10 in a reverse drive mode. As can be seen on a bar n 44 ', the output shaft 88 has a negative speed.
Der erste Leistungseingang 12 bzw. die erste Motoreinheit 14 ist mittels der Sperreinheit 24a gesperrt und die erste Motoreinheit 14 ist im Stillstand bzw. weist eine Drehzahl von Null auf, wie dies an einem Balken n4o' zu erkennen ist. Die Sperreinheit 24a dient zur Abstützung, so dass neben der in ihrer Drehrichtung umschaltbaren Motoreinheit 22 auch die Motoreinheit 20 zur Unterstützung bzw. zum Aufbau eines Abtriebsdrehmoments M88' im Rückwärtsfahrmodus genutzt werden kann, ohne dass diese umschaltbar ausgeführt werden muss. Beide Motoreinheiten 20, 22 werden als Motor betrieben und dienen zur Umwandlung elektrischer Energie in Drehmomente M20' , M22' •The first power input 12 and the first motor unit 14 is blocked by the blocking unit 24a and the first motor unit 14 is at a standstill or has a speed of zero, as can be seen on a bar n 4 o '. The blocking unit 24a serves to support, so that in addition to the switchable in its direction of rotation motor unit 22 and the motor unit 20 can be used to support or to build an output torque M 88 'in the reverse mode without these must be reversible. Both motor units 20, 22 are operated as a motor and serve to convert electrical energy into torques M 20 ', M 22 '.
Die Figur 7 zeigt eine alternative Sperreinheit 24b. Gleich¬ bleibende Bauteile und Funktionen sind grundsätzlich mit den gleichen Bezugszeichen versehen, wobei zur Unterscheidung der Sperreinheiten 24a, 24b, 24c den Bezugszeichen die Buchstaben „a", „b" und „c" hinzugefügt sind. Die nachfolgende Beschreibung beschränkt sich im Wesentlichen auf Unterschiede zu dem Ausführungsbeispiel in den Figuren 1 bis 6, wobei bzgl. gleicher Bauteile und Funktionen auf die vorangegangene Beschreibung verwiesen wird.FIG. 7 shows an alternative blocking unit 24b. Equal ¬ remaining components and functions are basically provided with the same reference numerals, and for distinguishing the locking units 24a, 24b, 24c to the reference numerals the letter "a", "b" and "c" are added. The following description is limited to substantially Differences from the exemplary embodiment in FIGS. 1 to 6, reference being made to the preceding description with regard to the same components and functions.
Die Sperreinheit 24b ist teilweise einstückig mit einer Anlassereinheit 30b zum Anlassen der ersten Motoreinheit 14 ausgeführt. Die Sperreinheit 24b weist eine Keilwelle 112b und ein auf der Keilwelle 112b gelagertes Zahnrad 114b auf. Das Zahnrad 114b ist drehfest mit der Keilwelle 112b verbunden und ist in axialer Richtung der Keilwelle 112b verschieb- bar auf derselben gelagert. Die Keilwelle 112b ist über einen Freilauf 32b der Sperreinheit 24b in eine erste Drehrichtung drehbar gelagert und eine zweite Drehrichtung gesperrt.The lock unit 24b is partially formed integrally with a starter unit 30b for starting the first motor unit 14. The locking unit 24b has a splined shaft 112b and a gear 114b mounted on the spline 112b. The gear 114b is non-rotatably connected to the splined shaft 112b and is displaceable in the axial direction of the spline 112b. bar stored on the same. The splined shaft 112b is rotatably supported by a freewheel 32b of the blocking unit 24b in a first rotational direction and a second rotational direction is locked.
Ferner umfasst die Sperreinheit 24b einen elektromagnetischen Aktuator 100b mit einer Spule 102b und einem mittels der Spule 102b betätigbaren Stößel 104b. Der Stößel 104b ist mit einer Schraubendruckfeder 106b verbunden, die vorgespannt zwischen dem Stößel 104b und einer Gabel 116b der Sperreinheit 24b angeordnet ist, die in das Zahnrad 114b eingreift. Die Sperreinheit 24b weist ferner eine Rückstelleinheit 34b mit einem von einer Schraubendruckfeder gebildeten Energiespeicher 36b auf. Die Schraubendruckfeder belastet die Gabel 116b in Richtung der Schraubendruckfeder 106b bzw. in Richtung einer Freigabestellung des Zahnrads 114b.Furthermore, the blocking unit 24b comprises an electromagnetic actuator 100b with a coil 102b and a plunger 104b which can be actuated by means of the coil 102b. The plunger 104b is connected to a helical compression spring 106b which is biased between the plunger 104b and a fork 116b of the locking unit 24b which engages the gear 114b. The blocking unit 24b furthermore has a reset unit 34b with an energy store 36b formed by a helical compression spring. The helical compression spring loads the fork 116b in the direction of the helical compression spring 106b or in the direction of a release position of the toothed wheel 114b.
Wird der Aktuator 100b von der Steuerungs- und Regelungseinheit 38 aktiviert, wird der Stößel 104b in Richtung der Gabel 116b verschoben und spannt dabei die Schraubendruckfeder 106b weiter vor, so dass die Gabel 116b und das Zahnrad 114b in Richtung dem von dem Zahnkranz gebildeten Sperrmittel 28 verschoben wird und das Zahnrad 114b mit seinen abgeschrägten Zähnen 110b gegen den evtl. noch langsam drehenden Zahnkranz gedrückt wird. Die abgeschrägten Zähne 110b können erst in das Sperrmittel 28 bzw. in den Zahnkranz einrasten, wenn eine Drehzahl des Zahnkranzes unter einen bestimmten Wert abfällt, und zwar wenn die erste Motoreinheit 14 nahezu zum Stillstand gekommen ist, wie dies in Figur 7 gestrichelt angedeutet ist. Wird der Aktuator 100b wieder deaktiviert, wird das Zahnrad 114b mittels der Rückstelleinheit 34b bzw. mittels der Schraubendruckfeder zurückgestellt .When the actuator 100b is activated by the control and regulation unit 38, the plunger 104b is displaced in the direction of the fork 116b, thereby further biasing the helical compression spring 106b so that the fork 116b and the gear 114b move in the direction of the blocking means 28 formed by the sprocket is moved and the gear 114b is pressed with its beveled teeth 110b against the possibly still slowly rotating ring gear. The chamfered teeth 110b can not engage in the locking means 28 or in the ring gear, when a speed of the ring gear drops below a certain value, namely when the first motor unit 14 has come almost to a standstill, as indicated by dashed lines in Figure 7. When the actuator 100b is deactivated again, the gear 114b is reset by means of the reset unit 34b or by means of the helical compression spring.
Die Keilwelle 112b ist ferner mittels eines Elektromotors, vorzugsweise mittel der Motoreinheit 20 oder 22, antreibbar, so dass über das Zahnrad 114b die Motoreinheit 14 durchgedreht und damit gestartet werden kann, und zwar wenn das Zahnrad 114b mit dem am Schwungrad 26 angeordneten Zahnkranz gekoppelt ist.The splined shaft 112b is furthermore drivable by means of an electric motor, preferably by means of the motor unit 20 or 22, so that via the gear 114b, the motor unit 14 can be turned and started with it, when the gear 114b is coupled to the arranged on the flywheel 26 sprocket.
In Figur 8 ist eine weitere alternative Sperreinheit 24c dargestellt. Anstatt einer translatorisch verschiebbaren Gabel 116b weist die Sperreinheit 24c einen über ein Drehgelenk 118c schwenkbar gelagerten Hebel 120c auf. Der Hebel 120c ist über ein Langloch 122c mit einem Zahnrad 114c verbunden und wird entsprechend der Ausführung in Figur 7 mittels eines e- lektromagnetischen Aktuators 100c betätigt. FIG. 8 shows a further alternative blocking unit 24c. Instead of a translationally displaceable fork 116b, the blocking unit 24c has a lever 120c pivotally mounted via a pivot 118c. The lever 120c is connected via a slot 122c to a gear 114c and is operated according to the embodiment in Figure 7 by means of an electromagnetic actuator 100c.
