Description
Die Erfindung betrifft eine Achsgetriebeeinheit für ein Kraftfahrzeug mit einem Getriebegehäuse, wobei die Achsgetriebeeinheit mit einer Antriebsachse wirkverbunden ist, wobei das Getriebegehäuse mindestens eine Kühlmittelleitung mit mindestens einem Vorlauf- und Rücklaufanschluss zur Kühlung eines Getriebeöls aufweist, wobei ein Getriebeölkanal vorgesehen ist, der benachbart zu der Kühlmittelleitung angeordnet ist.The invention relates to an axle gear unit for a motor vehicle with a gear housing, the axle gear unit being operatively connected to a drive axle, the gear housing having at least one coolant line with at least one flow and return connection for cooling a gear oil, a gear oil duct being provided which is adjacent to the Coolant line is arranged.
Eine derartige Achsgetriebeeinheit ist aus dem Stand der Technik, beispielsweise aus der
Aufgabe der vorliegenden Erfindung ist es daher, eine Achsgetriebeeinheit bereitzustellen, die einen optimalen Wärmeaustausch zwischen Kühlmittelleitung und Getriebeöl gewährleistet.The object of the present invention is therefore to provide an axle drive unit which ensures an optimal heat exchange between the coolant line and the transmission oil.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein Kühlmittelleitungsabschnitt zumindest im Bereich des Getriebeölkanals eine im Querschnitt langgestreckte Leitungsgeometrie besitzt, wobei die Leitungsgeometrie im Wesentlichen L-förmig ausgebildet ist, wobei ein kurzer Schenkel den Getriebeölkanal übergreift. Hierdurch kann auf besonders einfache und kostengünstige Art und Weise ein direkter Wärmeaustausch mit optimalem Wirkungsgrad zwischen Getriebeöl und Kühlmittel vorgesehen werden. In einer besonders vorteilhaften Ausführungsform verläuft die Kühlmittelströmung gegenläufig zur Ölströmung im Getriebeölkanal.This object is achieved according to the invention in that a coolant line section has, at least in the area of the transmission oil channel, a line geometry with an elongated cross-section, the line geometry being essentially L-shaped, with a short leg overlapping the transmission oil channel. In this way, a direct heat exchange with optimal efficiency between transmission oil and coolant can be provided in a particularly simple and inexpensive manner. In a particularly advantageous embodiment, the coolant flow runs in the opposite direction to the oil flow in the transmission oil duct.
Um eine Brennkraftmaschine des Kraftfahrzeuges möglichst schnell auf Betriebstemperatur zu bringen, weist das Getriebegehäuse in vorteilhafter Weise im Bereich des Vorlauf- und Rücklaufanschlusses eine schaltbare Bypassleitung auf.In order to bring an internal combustion engine of the motor vehicle to operating temperature as quickly as possible, the transmission housing advantageously has a switchable bypass line in the area of the flow and return connections.
In vorteilhafter Weise ist die Antriebsachse eine Vorderachse.The drive axle is advantageously a front axle.
