Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Verteilen eines Drehmomentes zwischen zwei antreibbaren Fahrzeugachsen gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art.The The invention relates to a device for distributing a torque between two drivable vehicle axles according to the preamble of claim 1 closer defined type.
Aus der Praxis sind Vorrichtungen zum Verteilen eines Antriebmomentes zwischen zwei antreibbaren Fahrzeugachsen eines Fahrzeuges bekannt. Derartige Vorrichtungen weisen eine Welle auf, die mit einer ersten antreibbaren Fahrzeugachse verbunden ist und auf der ein Zahnrad drehbar gelagert ist. Das Zahnrad ist über ein mit stufenlos variierbarer Übertragungsfähigkeit ausgeführtes reibschlüssiges Schaltelement, welches auch als so genannte Hang-On-Kupplung bezeichnet wird, drehfest mit der Welle in Wirkverbindung bringbar und mit der zweiten antreibbaren Fahrzeugachse verbunden. Das Antriebsmoment einer Brennkraftmaschine eines Fahrzeuges wird bei geöffnetem Schaltelement vollständig der mit der Welle verbundenen antreibbaren ersten Fahrzeugachse zugeführt. Ein Verteilungsgrad des Antriebsmomentes zwischen den antreibbaren Fahrzeugachsen variiert in Abhängigkeit der Übertragungsfähigkeit des Schaltelementes sowie der Reibwerte im Bereich der Antriebsräder des Fahrzeuges.Out In practice, devices for distributing a drive torque between two drivable vehicle axles of a vehicle. such Devices have a shaft which is driven by a first Vehicle axle is connected and on which a gear is rotatably mounted. The gear is over one with continuously variable transmissibility executed frictional switching element, which is also referred to as a so-called hang-on clutch, rotatably engageable with the shaft and operable with the second drivable Vehicle axle connected. The drive torque of an internal combustion engine of a vehicle is opened Switching element completely the drivable first vehicle axle connected to the shaft fed. A degree of distribution of the drive torque between the drivable vehicle axles varies depending on the transmission capacity of the switching element and the coefficients of friction in the drive wheels of the Vehicle.
Nachteilhafterweise sind die bekannten Vorrichtungen in axialer Richtung jeweils durch einen großen Bauraumbedarf gekennzeichnet, da das reibschlüssige Schaltelement neben dem Zahnrad beziehungsweise neben dem Übertragungselement angeordnet ist, um das Zahnrad mit der Welle betriebszustandsabhängig zu verbinden.Disadvantageously are the known devices in the axial direction respectively a big Required space, since the frictional switching element next to the Gear or arranged next to the transmission element is to the gear with the shaft operating state dependent too connect.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Verteilen eines Antriebsmomentes zwischen zwei antreibbaren Fahrzeugachsen eines Fahrzeuges zur Verfügung zu stellen, die zumindest in axialer Richtung einen geringeren Bauraumbedarf als herkömmlich ausgeführte Vorrichtungen aufweist.Of the The present invention is therefore based on the object, a device for distributing a drive torque between two drivable vehicle axles of a vehicle available to provide, at least in the axial direction a smaller space requirement as conventionally designed devices having.
Erfindungsgemäß wird diese Aufgabe mit einer Vorrichtung mit den Merkmalen des Patentanspruches 1 gelöst.According to the invention this Task with a device having the features of claim 1 solved.
Bei der erfindungsgemäßen Vorrichtung zum Verteilen eines Antriebsmomentes zwischen zwei antreibbaren Fahrzeugachsen eines Fahrzeuges mit einer Welle, die mit einer ersten antreibbaren Fahrzeugachse verbindbar ist, und einem drehbar auf der Welle gelagerten Zahnrad, welches über ein mit stufenlos variierbarer Übertragungsfähigkeit ausgeführtes reibschlüssiges Schaltelement drehfest mit der Welle in Wirkverbindung bringbar ist und das mit der zweiten antreibbaren Fahrzeugachse verbindbar ist, wobei das Antriebsmoment bei geöffnetem Schaltelement vollständig der mit der Welle verbindbaren antreibbaren ersten Fahrzeugachse zugeführt wird und ein Verteilungsgrad des Antriebsmomentes zwischen den antreibbaren Fahrzeugachsen in Abhängigkeit der Übertragungsfähigkeit des Schaltelementes variierbar ist, ist das Schaltelement innerhalb des Zahnrades angeordnet.at the device according to the invention for distributing a drive torque between two drivable Vehicle axles of a vehicle with a shaft connected to a first drivable vehicle axle is connectable, and a rotatable up The shaft mounted gear, which has a with infinitely variable transmission capacity executed frictional Switching element rotatably engageable with the shaft in operative connection is and that connectable to the second drivable vehicle axle is, wherein the drive torque when the switching element is fully the is supplied with the shaft connectable drivable first vehicle axle and a degree of distribution of the drive torque between the drivable ones Vehicle axles depending on the transmission capability of the switching element is variable, the switching element is within arranged the gear.
Die Vorrichtung nach der Erfindung ist auf einfache und kostengünstige Art und Weise in axialer Richtung im Vergleich zu herkömmlich ausgeführten Vorrichtungen mit Hang-On-Kupplungen durch einen geringeren Bauraumbedarf gekennzeichnet, da das reibschlüssige Schaltelement in einem bei aus dem Stand der Technik bekannten Vorrichtungen ungenutzten Bauraum innerhalb des Zahnrades und nicht neben dem Zahnrad angeordnet ist. Damit stellt die erfindungsgemäße Vorrichtung eine sehr kompakte Einheit dar, welche bauraumgünstig in einen Antriebsstrang eines Fahrzeuges integrierbar ist.The Device according to the invention is simple and inexpensive way and in the axial direction in comparison with conventionally designed devices characterized by a smaller space requirement with hang-on couplings, because the frictional Switching element in a known from the prior art devices unused space within the gear and not next to the Gear is arranged. Thus, the device of the invention provides a very compact unit, which space-saving in a drive train a vehicle can be integrated.
Weitere Vorteile und vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Patentansprüchen und den unter Bezugnahme auf die Zeichnung prinzipmäßig beschriebenen Ausführungsbeispielen, wobei in der Beschreibung der verschiedenen Ausführungsbeispiele der Übersichtlichkeit halber für bau- und funktionsgleiche Bauteile dieselben Bezugszeichen verwendet werden. Es zeigt:Further Advantages and advantageous developments of the invention result from the claims and the principle described with reference to the drawing Embodiments, in the description of the various embodiments of the clarity half for identical in construction and function Components are the same reference numerals.
