Antriebsstrang eines Allradfahrzeuges und ein Verfahren zum Steuern
und Regeln eines Antriebsstranges sind aus der
Mittels den zwischen dem Achsgetriebe und den Antriebsrädern jeweils angeordneten Schaltelementen der zweiten Fahrzeugantriebsachse ist das der zweiten Fahrzeugantriebsachse zugeführte Antriebsmoment in Fahrzeugquerrichtung mit in Abhängigkeit des aktuellen Betriebszustandes eines Fahrzeuges beliebig variierbaren Verteilungsgraden bedarfsgerecht zwischen den beiden Antriebsrädern verteilbar.through the switching elements arranged respectively between the axle drive and the drive wheels the second vehicle drive axle is that of the second vehicle drive axle supplied Drive torque in the vehicle transverse direction with depending the current operating state of a vehicle can be varied as desired Distribution levels can be distributed as required between the two drive wheels.
Nachteilig dabei ist jedoch, dass zwischen der Verbrennungsmaschine und dem Abtrieb des Fahrzeuges bei Übersetzungsänderungen im Schaltgetriebe auftretende Differenzdrehzahlen über beispielsweise als reibschlüssige Lamellenkupplungen oder Lamellenbremsen bzw. als Synchronisierungen ausgeführte und übergangsweise schlupfend betriebene Schaltelemente auszugleichen sind, die während des Schlupfbetriebes einen die Lebensdauer verringernden Verschleiß ausgesetzt sind und zudem nur mit einem hohen Steuer- und Regelaufwand sowie in geöffnetem Zustand mit hohen Schleppverlusten betreibbar sind. Des Weiteren werden die Schaltelemente während ihres Schlupfbetriebes durch die auftretende Verlustleistung stark erwärmt und sind daher durch ein geeignetes Schmier- und Kühlsystem mit einer entsprechend hohen Schmier- und Kühlölmenge zu versorgen.adversely However, it is that between the internal combustion engine and the Downforce of the vehicle during translation changes occurring in the manual transmission differential speeds over, for example as frictional multi-plate clutches or Multi-disc brakes or executed as synchronizations and transitional slipping operated switching elements are to be compensated during the Slip operation exposed the life-reducing wear are and only with a high tax and regulatory overhead and in open Condition with high drag losses are operable. Furthermore be the switching elements during their slipping operation by the power loss strong heated and are therefore through a suitable lubrication and cooling system to supply with a correspondingly high amount of lubricating and cooling oil.
Darüber hinaus sind derartige Fahrzeuge, um beispielsweise die Verbrennungsmaschine zu starten, ein elektrisches Bordnetz zu versorgen oder eine elektrische Speichereinrichtung zu laden, mit einem Anlasser und einem elektrischen Generator bzw. einer Lichtmaschine ausgeführt und daher durch eine die Herstellkosten erhöhende Bauteilanzahl gekennzeichnet.Furthermore are such vehicles, for example, the internal combustion engine to start, to supply an electric vehicle electrical system or an electrical Storage device to load, with a starter and an electric Run generator or an alternator and therefore by a the Increasing manufacturing costs Part number marked.

Zwischen den Antriebsaggregaten und einem Abtrieb der Hybridfahrzeuge ist üblicherweise jeweils ein automatisiertes Schaltgetriebe angeordnet, um verschiedene Übersetzungen für eine Vorwärtsfahrt und für eine Rückwärtsfahrt zur Verfügung stellen zu können. Zudem ist im Bereich einer Fahrzeugantriebsachse ein Achsgetriebe zum Verteilen des der Fahrzeugantriebsachse zugeführten Antriebsmomentes zwischen den Antriebsrädern der Fahrzeugantriebsachse vorgesehen.Out The practice known hybrid vehicles are in addition to an internal combustion engine with at least one electric machine for starting the internal combustion engine, to supply an electrical system and to charge a electrical energy storage, the emission-free pure electrical machine side Running the hybrid vehicle and the like executed. Between The drive units and an output of the hybrid vehicles is usually each arranged an automated manual transmission to various translations for one driving forward and for a reverse drive to disposal to be able to make. In addition, in the range of a vehicle drive axle is a axle drive for distributing the vehicle drive shaft supplied drive torque between the drive wheels provided the vehicle drive axle.
Bei derartigen Hybridfahrzeugen sind im Bereich zwischen den Antriebsaggregaten und dem Abtrieb während Schaltvorgängen im Schaltgetriebe auf tretende Drehzahländerungen auch über reibschlüssige Schaltelemente mit den bekannten Nachteilen auszugleichen. Eine variable Drehmomentverteilung in Fahrzeuglängsrichtung zwischen zwei Fahrzeugantriebsachsen und/oder in Fahrzeugquerrichtung zwischen zwei Antriebsrädern einer Fahrzeugantriebachse ist mit solchen Antriebssystemen nicht durchführbar.at Such hybrid vehicles are in the range between the drive units and the downforce during switching operations in the manual gearbox on passing speed changes via frictional switching elements to compensate with the known disadvantages. A variable torque distribution in the vehicle longitudinal direction between two vehicle drive axles and / or in the vehicle transverse direction between two drive wheels a vehicle drive axle is not with such drive systems feasible.
