Description
Die Erfindung betrifft einen Hybridfahrzeugantriebsstrang gemäß dem Oberbegriff von Anspruch 1, dem Oberbegriff von Anspruch 2. Ferner betrifft die Erfindung einen Hybridfahrzeugantriebsstranggemäß dem einteiligen Anspruch 11.The invention relates to a hybrid vehicle drive train according to the generic term of claim 1, the preamble of claim 2 further relates the invention a hybrid vehicle powertrain according to the one-piece Claim 11.
Die nicht vorveröffentlichte
Aufgabe der Erfindung gemäß Patentanspruch 1 ist es, einen auch unter höchsten Belastungen ausfallsicheren Antriebsstrang zu schaffen.Object of the invention according to claim 1 is one, even among the highest Loads fail-safe powertrain to create.
Ein Vorteil von Patentanspruch 1 ist der, dass die Kreiselmomente der dem Getriebe näher stehenden elektrischen Maschine von Lagern einer Durchgangswelle abgestützt werden. Solche Kreiselmomente entstehen, wenn sich der sehr schwere und damit massenträge Rotor der elektrischen Maschine schnell dreht und das Kraftfahrzeug mit hoher Winkelgeschwindigkeit um die Hochachse dreht, wie dies bei glatter Fahrbahn passieren kann. Weiterhin können diese hohen Kreiselmomente bei Stampfbewegungen des Motor-Getriebeverbandes während des Überfahrens von Bodenwellen auftreten. Dabei entstehen die besagten Kreiselkräfte als hohe Reaktionskräfte, die erfindungsgemäß sicher abgestützt werden. Die Lager der Durchgangswelle sind zum einen in einer Ausnehmung der Kurbelwelle des Verbrennungsmotors und zum anderen an einem Gehäuseteil angeordnet, welches insbesondere als Lagerhals ausgestaltet sein kann. Dabei kann das innerhalb des Gehäuseteils angeordnete Lager besonders groß dimensioniert und radial innerhalb der dem Getriebe näher stehenden elektrischen Maschine angeordnet sein, so dass neben den hohen Kreiselmomenten das Eigengewicht und die technisch bedingte Unwucht des Rotors der elektrischen Maschine problemlos von diesem Lager aufgenommen werden können.An advantage of claim 1 is that the gyroscopic moments closer to the gearbox electric machine are supported by bearings of a through shaft. Such gyroscopic moments arise when the very heavy and thus mass sluggish Rotor of the electric machine turns fast and the motor vehicle rotates at high angular velocity about the vertical axis, as with slippery roads can happen. Furthermore, these high gyroscopic moments during ramming movements of the engine-gearbox while driving over from bumps occur. This creates the said centrifugal forces as high reaction forces, the invention safe be supported. The bearings of the through shaft are on the one hand in a recess the crankshaft of the internal combustion engine and on the other at one housing part arranged, which are designed in particular as a bearing neck can. In this case, the arranged within the housing part bearing especially large dimensions and radially within the closer to the transmission electrical Machine be arranged so that in addition to the high gyroscopic moments the dead weight and the technical imbalance of the rotor of electric machine can be easily absorbed by this camp.
In einer besonders vorteilhaften Ausgestaltung der Erfindung kann der Lagerhals, in dessen Ausnehmung das vorgenannte Lager aufgenommen wird, auch einen Ausrückkolben eines Zentralausrückers aufnehmen. Mit diesem ist dann die Kupplung ein und ausrückbar. Wie weiter unten näher erläutert, kann der Gehäuseteil, welcher den Lagerhals bildet, auch eine mechanisch und/oder elektrisch angetriebene Ölpumpe aufnehmen.In a particularly advantageous Embodiment of the invention, the bearing neck, in its recess the aforementioned bearing is received, also a release piston a central release take up. With this then the clutch is disengaged and. How closer below explained, can the housing part, which forms the bearing neck, also a mechanical and / or electrical driven oil pump take up.
Die konstruktive Ausgestaltung insbesondere gemäß Patentanspruch 10 ermöglicht es in vorteilhafter Weise den Hybridfahrzeugantriebsstrang als modulare Alternative zu einem hydrodynamischen Drehmomentwandler eines Automatikgetriebes herzustellen. Dadurch kann bei verschiedenen Fahrzeugtypen – d.h. solchen mit Wandlerautomatikgetriebe und solche mit Hybridantrieb – der gleiche Rohbau verwendet werden. Lediglich die Batterie für den Hybridfahrzeugantriebsstrang gilt es im besonderen Maße baulich zu beachten. Ansonsten können die üblichen Bauteile des Automatikgetriebes verwendet werden. Damit gehen Kostenvorteile einher.The structural design in particular according to claim 10 allows it advantageously the hybrid vehicle powertrain as modular Alternative to a hydrodynamic torque converter of an automatic transmission manufacture. This may result in different types of vehicles - i. such a with converter automatic transmission and those with hybrid drive - the same shell be used. Only the battery for the hybrid vehicle powertrain it applies in a special way structurally. Otherwise, the usual Components of the automatic transmission are used. There are cost advantages associated.
Aufgabe von Patenanspruch 2 ist es, einen möglichst kompakten Hybridfahrzeugantriebsstrang zu schaffen.The task of claim 2 is one possible to create compact hybrid vehicle powertrain.
Dabei erfolgt die Kupplungsbetätigung durch einen Steg hindurch, welcher den Rotor der dem Getriebe näher stehenden elektrischen Maschine trägt. Der Steg kann dabei in besonders vorteilhafter Weise als Stegscheibe ausgestaltet sein, wie dies im Patentanspruch 16 beansprucht ist.The clutch is actuated by a Bridge through which the rotor of the gear closer to the electric Machine carries. Of the Bridge can in a particularly advantageous manner as a bridge disc be configured as claimed in claim 16.
Der Hybridfahrzeugantriebsstrang hat generell einen Kraftstoffverbrauchsvorteil.The hybrid vehicle powertrain generally has a fuel economy advantage.
Der Hybridfahrzeugantriebsstrang kann bei besonders langsamen Fahrgeschwindigkeiten als serieller Hybrid betrieben werden. Dabei ist die Kupplung offen und die erste – bzw. getriebenahe – elektrische Maschine wird als Generator betrieben, dessen Spannung die als Motor betriebene zweite – bzw. motornahe – elektrische Maschine antreibt. Als Puffer ist dabei die Batterie zwischengeschaltet. Da langsame Geschwindigkeiten bewerkstelligt werden, kann die Kupplung besonders vorteilhaft als Reibtrockenkupplung ausgeführt sein, was mit Kostenvorteilen und Wirkungsgradvorteilen einhergeht, da kein spezieller Schmiermittelkreislauf notwendig ist. Im Normalfall wird die Kupplung bei Drehzahlgleichheit der beiden Kupplungshälften eingerückt, so dass keine, ausgeprägte Schlupfphase mit entsprechender Reibarbeit auftritt. Im Idealfall wird überhaupt keine Reibarbeit verrichtet.The hybrid vehicle powertrain can be used as serial at particularly slow speeds Hybrid operated. The coupling is open and the first - or geared - electrical Machine is operated as a generator whose voltage is the engine operated second - or close to the engine - electric Machine drives. As a buffer while the battery is interposed. Since slow speeds are accomplished, the clutch can be particularly advantageous designed as a dry rub clutch What goes along with cost advantages and efficiency advantages, since no special lubricant circuit is necessary. Normally will the clutch engaged with equal speed of the two coupling halves, so that no, pronounced Slip phase with appropriate friction work occurs. Ideally will ever does no friction work.
Aufgabe der Erfindung gemäß Patentanspruch 11 ist es, einen kostengünstigen und dennoch ausfallsicheren Hybridfahrzeugantriebsstrang zu schaffen.Object of the invention according to claim 11 is a cost-effective yet to provide fail-safe hybrid vehicle powertrain.
Bei dem Hybridfahrzeugantriebsstrang können in besonders vorteilhafter Weise zwei Ölpumpen zur Öldruckversorgung des Automatikgetriebes und – bei Bedarf zusätzlich – des großen Lagers vorhanden sein. Dabei kann die eine Ölpumpe als mechanische Ölpumpe ausgestaltet sein, wohingegen die andere Ölpumpe elektrisch betrieben ist. Die mechanisch betriebene Ölpumpe kann vorzugsweise eine von der Getriebeeingangswelle angetriebene Mondsichelpumpe sein, welche ebenfalls in dem Gehäuseteil untergebracht ist, welches den Lagerhals zur Aufnahme großen Lager und des Ausrückkolbens bildet. Bei der Verwen dung einer mechanischen und einer elektrischen Ölpumpe können beide über ein Rückschlagventil an eine Druckleitung des Automatikgetriebes angeschlossen sein.In the hybrid vehicle drive train two oil pumps for oil pressure supply of the automatic transmission and - if necessary in addition - the large bearing can be present in a particularly advantageous manner. In this case, the one oil pump can be configured as a mechanical oil pump, whereas the other oil pump is electrically operated. The mechanically operated oil pump may preferably be a crescent pump driven by the transmission input shaft, which is also accommodated in the housing part, which forms the bearing neck for receiving large bearings and the release piston. When using a mechanical and an electric oil pump, both can have a setback valve to be connected to a pressure line of the automatic transmission.
Alternativ zu einer mechanischen und einer getrennten elektrischen Ölpumpe kann auch eine einzige Ölpumpe vorgesehen sein, welche sowohl mechanisch als auch elektrisch antreibbar ist. Eine solche Ölpumpe könnte beispielsweise so aussehen, dass die Getriebeeingangswelle und der Elektromotor gemeinsam über ein Überlagerungsgetriebe bzw. Freiläufe die Ölpumpe antreiben, wobei der Elektromotor – falls stromlos geschaltet – gegen Rückwärtsdrehen durch einen Freilauf gesichert ist. Aber selbst bei Verwendung einer einzigen Ölpumpe ist für den Fall, dass diese nur elektrisch betrieben wird, der worst case – d.h. den maximal möglichen Belastungsfall – abzudecken. Dieser worst case tritt beispielsweise dann auf, wenn das Kraftfahrzeug quer zum Bordstein steht, die Kupplung zum seriellen Betrieb der beiden elektrischen Maschinen als Anfahrelement geöffnet ist und somit ein hohes Drehmoment von der einen getriebenahen elektrischen Maschine aufgebracht wird, obwohl das Fahrzeug steht. Dieses hohes Drehmoment wird in das Automatikgetriebe geleitet. Wenn dann das Öl im Getriebe infolge einer hohen Temperatur dünnflüssig ist und damit hohe Leckagen verursacht, kann der Getriebeölarbeitsdruck in Höhe von 25bar nur aufgebracht werden, wenn die elektrisch betriebene Ölpumpe einen Elektromotor mit einer hohen Leistung von über 1kW aufweist.Alternatively to a mechanical one and a separate electric oil pump may also provide a single oil pump be, which is both mechanically and electrically driven. Such an oil pump could For example, look like that the transmission input shaft and the Electric motor together over a superposition gearbox or freewheels the oil pump drive, wherein the electric motor - if de-energized - against reverse rotation secured by a freewheel. But even when using a single oil pump is for the case that this is operated only electrically, the worst case - i. the maximum possible Load case - cover. This worst case occurs, for example, when the motor vehicle is transverse to the curb, the clutch for serial operation of both electric machines is opened as a starting element and thus a high torque from the one driven electric Machine is applied even though the vehicle is stationary. This tall Torque is directed into the automatic transmission. If then the oil in the transmission is fluid due to a high temperature and thus causes high leakage, the transmission oil working pressure in Height of 25bar only be applied when the electrically operated oil pump a Electric motor with a high power of over 1kW.
In einer besonders kostengünstigen, kleinen und leichten Ausgestaltung der Erfindung wird ein auf den anspruchsvollen Normalfall dimensionierter – d.h. relativ kleiner – Elektromotor verwendet, der zudem den Vorteil hat, dass die Elektromotorkühlung geringer dimensioniert werden kann. Wenn bei einem solch gering dimensionierten Elektromotor der vorgenannte worst Gase eintritt, fällt der Getriebeölarbeitsdruck auf unter 25bar wobei je nach Höhe des Getriebeölarbeitsdrucks die Lammellenkupplungen/-bremsen des Automatikgetriebes schlup fen. Demzufolge wird die Getriebeeingangswelle von der als Elektromotor betriebenen getriebenahen elektrischen Maschine in Rotation versetzt, so dass der zusätzliche mechanische Antrieb den zusätzlichen Ölförderstrom liefert, um den Getriebeölarbeitsdruck auf über 25bar zu erhöhen. Im Falle einer einzigen Ölpumpe, welche sowohl mechanisch als auch elektrisch antreibbar ist, wird der Gesamtförderstrom der Ölpumpe erhöht. Im Falle einer mechanischen und einer von dieser getrennten elektrischen Ölpumpe ergeben beide Volumenströme zusammen den ausreichenden Gesamtförderstrom, um die Lammellenkupplungen/-bremsen des Automatikgetriebes zu versorgen.In a particularly inexpensive, small and light embodiment of the invention is a on the demanding normal case dimensioned - i. relatively small - electric motor used, which also has the advantage that the electric motor cooling is lower can be dimensioned. If at such a small size Electric motor of the aforementioned worst gases occurs, the falls Transmission fluid operating pressure on under 25bar depending on height the transmission oil working pressure the Lammellenkupplungen / brakes of the automatic transmission slip fen. Consequently, the transmission input shaft of the as an electric motor driven electric machine in rotation, so that the additional mechanical Drive supplies the additional oil flow, around the transmission oil working pressure on over 25bar increase. In the case of a single oil pump, which is both mechanically and electrically driven, is the total flow rate the oil pump elevated. In the case of a mechanical and a separate from this electric oil pump both volume flows together the sufficient total flow to the Lammellenkupplungen / brakes of the automatic transmission.
In einer besonders vorteilhaften Ausgestaltung kann der Öldruck an zumindest einer Lamellenkupplung im Getriebe gezielt abgesenkt werden, so dass es geringfügig zum Schlupf kommt, damit bei Fahrzeugstillstand der Elektromotor drehen kann, um eine Überlastung einzelner Wicklungen der zweiten Elektrischen Maschine zu verhindern.In a particularly advantageous Design, the oil pressure specifically lowered on at least one multi-plate clutch in the transmission be so minor slippage occurs so that when the vehicle is stationary, the electric motor can turn to overload individual windings of the second electric machine to prevent.
In einer besonders vorteilhaften Ausgestaltung des Elektromotors für die Ölpumpe, welcher auf den anspruchsvollen Normalfall – d.h., relativ klein – dimensioniert ist, ist eine besondere Steuerungseinrichtung vorgesehen. Diese Steuerungseinrichtung steuert bzw. regelt u.a. den das Drehmoment der dem Getriebe nahe stehenden elektrischen Maschine. Dabei verhindert die Steuerungseinrichtung, dass beim vorgenannten Schlupfen die Lammellenkupplungen/-bremsen überlastet werden. Dabei werden für die Lammellenkupplungen/-bremsen Lammellen verwendet, welche zwar ein langzeitiges Schlupfen nicht vertragen, jedoch kurzzeitiges Schlupfen von beispielsweise 1 Sekunde beliebig oft vertragen. Die besagte Steuerungseinrichtung überwacht dabei die Schlupfdauer der Lammellenkupplungen/-bremsen des Automatikgetriebes, wobei ein kurzzeitiges Schlupfen zugelassen wird. Wird ein Grenzwert der Schlupfdauer überschritten, so reduziert die Steuerungsseinrichtung das Drehmoment der zweiten elektrischen Maschine, so dass diese ein geringeres Drehmoment in die Getriebeeingangs welle einleitet. Dabei wird das Drehmoment so weit reduziert, bis die Lammellenkupplung/-bremse nicht mehr schlupft oder alternativ bis die Drehzahldifferenz an der schlupfenden Lammellenkupplung/-bremse so gering ist, dass keine thermische Schädigung der Lamellen eintritt. Eine Möglichkeit zur Ermittlung der Drehzahldifferenz an der Lammellenkupplung/-bremse ist der Vergleich der Getriebeeingangswellendrehzahl mit der Getriebeausgangswellendrehzahl, wobei der derzeit eingelegte Getriebegang berücksichtigt wird. Anstelle der Getriebeausgangswellendrehzahl kann auch die Drehzahl an den Antriebsrädern gemessen werden, wobei das Übersetzungsverhältnis des üblicherweise vorhandenen Differentials berücksichtigt wird. Ferner wird in der Berechnung der Getriebeausgangswellendrehzahl anhand der Drehzahl an den Antriebsrädern berücksichtigt, dass die zwei bzw. beim Allradantrieb vier Antriebsräder unterschiedliche Drehzahlen aufweisen. Bei dem Differential handelt es sich im Falle eines Vorderachsantriebes um eine Frontdifferential und im Falle eines Hinterachsantriebes um ein Hinterachsdifferential. Um das Drehmoment der elektrischen Maschine zu verringern, kann die Steuerungsseinrichtung über eine Wechselrichtereinheit bzw. eine Leistungsrichtereinheit der dem Getriebe nahe stehenden elektrischen Maschine verbunden sein. Dabei beeinflußt die Wechselrichtereinheit bzw. die Leistungsrichtereinheit das Drehmoment der besagten elektrischen Maschine, indem die Amplitude/Phase/Frequenz der Strangströme beeinflußt wird. Spannungsquelle der Wechselrichtereinheit ist zum einen die dem Verbrennungsmotor nahe stehende elektrische Maschine, welche als Generator betrieben wird. Ferner ist als Spannungsquelle bzw. als Puffer eine Batterie oder alternativ ein Superkondensator vorgesehen.In a particularly advantageous Design of the electric motor for the oil pump, which on the demanding Normal case - that is, relatively small - sized is, a special control device is provided. This Control device controls or regulates inter alia. the torque the electric machine close to the transmission. It prevents the control device that in the aforementioned slippage the Overhead clutches / brakes overloaded become. It will be for The Lammellenkupplungen / brakes Lammellen used, although can not tolerate long-term slippage, but short-term Slack of, for example, 1 second as often tolerated. The said Control device monitored while the slippage duration of the Lammellenkupplungen / brakes of the automatic transmission, whereby a brief slippage is allowed. Becomes a limit the slip time exceeded, Thus, the control device reduces the torque of the second electrical Machine, so that this lower torque in the transmission input shaft initiates. The torque is reduced so far until the Lammellenkupplung / brake no longer slips or alternatively until the speed difference the slipping Lammellenkupplung / brake is so low that no thermal damage the lamellae enters. A possibility for determining the speed difference at the Lammellenkupplung / brake is the comparison the transmission input shaft speed with the transmission output shaft speed, whereby the currently engaged gear is taken into account. Instead of Transmission output shaft speed can also be the speed measured at the drive wheels be, with the gear ratio of the usual considering the existing differential becomes. Further, in the calculation, the transmission output shaft speed Based on the speed at the drive wheels taken into account that the two or four-wheel drive four drive wheels different speeds respectively. The differential is in the case of a Vorderachsantriebes around a front differential and in the case of a Hinterachsantriebes around a rear axle differential. To the torque of the electric To reduce the machine, the control device can have an inverter unit or a power converter unit close to the transmission be connected electrical machine. The inverter unit influences this or the power converter unit, the torque of the said electrical Machine by influencing the amplitude / phase / frequency of the phase currents. Voltage source of the inverter unit is on the one hand the Combustion engine related electric machine, which as Generator is operated. Furthermore, as a voltage source or as Buffer a battery or alternatively a supercapacitor provided.
Im zuvor geschilderten worst case am Bordstein liegt also ein so hohes Drehmoment an der dem Getriebe nahe stehenden elektrischen Maschine an, dass die Fahrzeugräder sich in jedem Fall drehen müssen. Kurz danach liegt eine so hohe Fahrgeschwindigkeit vor, dass die Summenförderleistung der Ölpumpen ausreicht, um ein hinreichendes Drehmoment durch die Lammellenkupplungen/-bremsen des Automatikgetriebes zu leiten.In the previously described worst case on the curb is so high torque at the Gearbox related electric machine that the vehicle wheels must turn in any case. Shortly thereafter, there is such a high driving speed that the total output of the oil pumps is sufficient to conduct a sufficient torque through the Lichellenkupplungen / brakes of the automatic transmission.
Sollte bei der ausführlich geschilderten Verwendung einer relativ klein dimensionierten elektrischen Ölpumpe mit einem zusätzlichen mechanischen Antrieb oder einer zusätzlichen mechanischen Ölpumpe dennoch unter Last eine zu hohe Schlupfdauer im Getriebe auftreten, gibt es zwei Abregelmöglichkeiten. Zum einen kann die vorgenante Drehmomentreduktion der dem Getriebe nahe stehenden elektrischen Maschine durchgeführt werden. Zum anderen können im Automatikgetriebe durch dessen Getriebesteuerung Hochschaltungen verhindert werden. Infolgedessen bleibt die Getriebeeingangswelle auf einem relativ hohen Drehzahlniveau, so dass auch die Förderleistung der mechanischen Pumpe auf einem relativ hohen Niveau bleibt.Should be at the detailed Use of a relatively small-sized electric oil pump with an additional mechanical drive or an additional mechanical oil pump nevertheless under load a too long slip time in the transmission occur, there There are two Abregelmöglichkeiten. For one, the vorgenante torque reduction of the transmission be performed nearby electric machine. On the other hand, in the Automatic transmission through its transmission control upshifts be prevented. As a result, the transmission input shaft remains on a relatively high speed level, so that the capacity the mechanical pump remains at a relatively high level.

Das Ausrücklager, welches die Relativdrehbarkeit zwischen der Druckplatte und dem Ausrückkolben herstellt, kann dabei sowohl motorseitig als auch getriebeseitig vom Steg des zweiten Rotors angeordnet sein. In diesem Fall sorgt eine Druckfeder innerhalb des Druckraumes des Zentralausrückers für das ständig notwendige Anliegen des Ausrückkolbens an der Druckplatte. Die Trockenkupplung ist in diesem Fall aktiv schließend anstatt aktiv öffnend.In an alternative embodiment The invention can be applied to the linkage between the release piston and the axially displaceable pressure plate of the rubbing dry clutch be waived. It is based the release piston by means of tongues themselves through the recesses of the web on the axially displaceable pressure plate. The release bearing, which the relative rotation between the pressure plate and the release piston manufactures, it can be both the motor side and the transmission side be arranged from the web of the second rotor. In this case, take care a compression spring within the pressure chamber of the Zentralausrückers for the ever-necessary concern the release piston on the pressure plate. The dry clutch is active in this case closing instead actively opening.
