Description

Die vorliegende Erfindung betrifft einen Zusammenbau (ZSB) für einen elektrischen Antrieb. Die vorliegende Erfindung betrifft darüber hinaus einen entsprechende Antriebsstrang sowie ein entsprechendes Elektrofahrzeug.The present invention relates to an assembly (ZSB) for an electric drive. The present invention also relates to a corresponding drive train and a corresponding electric vehicle.

In der Fahrzeugtechnik wird als aktive Gierregelung (active yaw control) oder Drehmomentverteilung (torque vectoring) die aktive Beeinflussung des Gierwinkels (yaw angle) oder der Gierrate (yaw rate) bezeichnet. Eine Gierregelung nach dem Stand der Technik trägt als Fahrerassistenzsystem durch die kontrollierte Umverteilung der Antriebsmomente erheblich zu einem dynamischen Fahrverhalten bei.In vehicle technology, the active influencing of the yaw angle (yaw angle) or the yaw rate (yaw rate) is called active yaw control or torque distribution (torque vectoring). As a driver assistance system, state-of-the-art yaw control makes a significant contribution to dynamic driving behavior through the controlled redistribution of drive torque.

Gängige Systeme dieser Gattung sind elektronisch gesteuert und können bei einem Lenkeinschlag wahlweise entweder das langsamere (kurveninnere) oder das schnellere (kurvenäußere) Rad mit einem erhöhten Drehmoment beaufschlagen, um die Kurvenfahrt gezielt zu unterdrücken beziehungsweise zu unterstützen. Hierzu wird typischerweise ein komplex aufgebautes Differential eingesetzt, welches die Antriebskraft - ähnlich der sogenannten Panzerlenkung - aktiv auf die beiden Räder verteilt.Common systems of this type are electronically controlled and can apply increased torque to either the slower (inside the curve) or the faster (outside) wheel when turning the steering wheel in order to specifically suppress or support cornering. For this purpose, a complex differential is typically used, which actively distributes the driving force to the two wheels - similar to the so-called tank steering.

Dabei kann etwa zusätzlich zum Antriebsmoment der Hauptelektromaschine, welches durch ein Ausgleichsgetriebe gleichmäßig aufgeteilt wird, mithilfe eines zweistufigen Planetenüberlagerungsgetriebe ein Differenzmoment zwischen den beiden Rädern der Antriebsachse erzeugt werden, das somit nicht vom Hauptantriebsmoment abhängt. Zu diesem Zweck wird beispielsweise ein mittiges Kegelrad von einem eigenen Hydraulikmotor bewegt, welcher wiederum von der Hauptmaschine angetrieben wird. Bekannt ist ferner eine Drehmomentverteilung mittels elektrischer Stellantriebe (electric torque vectoring, eTV).In addition to the drive torque of the main electric machine, which is evenly divided by a differential gear, a differential torque can be generated between the two wheels of the drive axle using a two-stage planetary superposition gear, which therefore does not depend on the main drive torque. For this purpose, for example, a central bevel gear is moved by its own hydraulic motor, which in turn is driven by the main machine. Torque distribution using electric actuators (electric torque vectoring, eTV) is also known.

Die Erfindung stellt einen Zusammenbau für einen elektrischen Antrieb, einen entsprechende Antriebsstrang sowie ein entsprechendes Elektrofahrzeug gemäß den unabhängigen Ansprüchen bereit.The invention provides an assembly for an electric drive, a corresponding drive train and a corresponding electric vehicle according to the independent claims.

Die erfindungsgemäße Integration des eTV in den Zusammenbau bietet den Vorzug, dass dessen Versorgung für mehrere Komponenten genutzt werden kann, denen die für den Fahrbetrieb vorgehaltene elektrische Maschine als zentraler Drehmomenterzeuger dient.The inventive integration of the eTV into the assembly offers the advantage that its supply can be used for several components, for which the electric machine provided for driving serves as a central torque generator.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben. So kann eine Hydraulikpumpe vorgesehen sein, welche den Versorgungsdruck für die Maschine sowie für deren Getriebe liefert. Somit kann auch der für den Antrieb erforderliche hydraulische Druck von einer einzigen zentralen Pumpe ausgeübt werden.Further advantageous embodiments of the invention are specified in the dependent claims. A hydraulic pump can be provided, which supplies the supply pressure for the machine and its transmission. This means that the hydraulic pressure required for the drive can be exerted by a single central pump.

Schließlich mag die Integration einer ADR vorgesehen sein, deren hydraulischer Versorgungsdruck ebenfalls von besagter Pumpe geliefert wird. Eine entsprechende Ausführungsform gestattet es, die ADR in die gemeinsame Versorgung einzubeziehen.Finally, the integration of an ADR may be provided, the hydraulic supply pressure of which is also supplied by said pump. A corresponding embodiment allows the ADR to be included in the shared supply.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden näher beschrieben.

  • 1 zeigt die Zusammenbauten für Antrieb, eTV und ADR eines Elektrofahrzeuges nach dem Stand der Technik.
  • 2 zeigt einen hochintegrierten Zusammenbau gemäß einer Variante der Erfindung.
An exemplary embodiment of the invention is shown in the drawings and is described in more detail below.
  • 1 shows the assemblies for the drive, eTV and ADR of an electric vehicle according to the state of the art.
  • 2 shows a highly integrated assembly according to a variant of the invention.

1 illustriert das der Erfindung zugrundeliegende Problem anhand eines herkömmlichen elektrischen Antriebsstranges (10, 20, 30): Neben dem Zusammenbau (10) für den Hauptantrieb sind weitere Zusammenbauten (20, 30) für eTV beziehungsweise ADR vorgesehen, welche jeweils getrennter Versorgung und eines eigenen Gehäuses bedürfen. 1 illustrates the problem underlying the invention using a conventional electric drive train (10, 20, 30): In addition to the assembly (10) for the main drive, further assemblies (20, 30) are provided for eTV or ADR, each with a separate supply and its own housing need.

2 stellt dieser herkömmlichen Anordnung einen erfindungsgemäßen Zusammenbau (10) gegenüber. Deren Pulswechselrichter (11) mit einer Eingangsspannung von 800 V speist hier eine einzige elektrische Maschine (12), deren Drehmoment über ein zweiteiliges Getriebe (13) auf Hauptantrieb und eTV verteilt wird. Eine lösbare Kupplung gestattet es hierbei, das Drehmoment für die Gierregelung bei Geradeausfahrt zu unterdrücken und somit weitgehend unabhängig vom Hauptantriebsmoment zu steuern. 2 compares this conventional arrangement with an assembly (10) according to the invention. Their pulse inverter (11) with an input voltage of 800 V feeds a single electric machine (12), the torque of which is distributed to the main drive and eTV via a two-part gearbox (13). A releasable clutch allows the torque for yaw control to be suppressed when driving straight ahead and thus controlled largely independently of the main drive torque.

Der Zusammenbau (10) umfasst ferner eine Ölpumpe (14) mit einer Eingangsspannung von 12 V, welche den hydraulischen Versorgungsdruck für Maschine (12), Getriebe (13) und aktive Dämpfungsregelung (15) liefert. Ein exemplarisch als Kugelhahn dargestelltes Absperrorgan erlaubt es, den Versorgungsdruck für letztere Regelung (15) wahlweise zu sperren. Es versteht sich indes, dass der Versorgungsdruck der Dämpfungsregelung (15) mithilfe einer anderweitigen Armatur gesteuert werden mag, ohne den Rahmen der Erfindung zu verlassen.The assembly (10) further includes an oil pump (14) with an input voltage of 12 V, which supplies the hydraulic supply pressure for the machine (12), transmission (13) and active damping control (15). A shut-off device, shown as an example as a ball valve, allows the supply pressure for the latter control (15) to be optionally blocked. It goes without saying, however, that the supply pressure of the damping control (15) can be controlled using another fitting without departing from the scope of the invention.

Ein gestrichelt umrissenes Gehäuse beherbergt sämtliche Komponenten (11, 12, 13, 14, 15) des Zusammenbaus (10) und stellt die Anschlüsse für dessen Spannungsversorgung bereit.A housing outlined in dashed lines houses all the components (11, 12, 13, 14, 15) of the assembly (10) and provides the connections for its power supply.
