Abstract
Description
Die Erfindung betrifft eine Kühlmittelpumpe eines Antriebsaggregats eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1.The The invention relates to a coolant pump of a drive unit of a motor vehicle according to the preamble of claim 1.
Aus
der
Hiervon ausgehend liegt der hier vorliegenden Erfindung die Aufgabe zugrunde, eine neuartige Kühlmittelpumpe zu schaffen, die einfach zugeschaltet und abgeschaltet werden kann.Of these, Based on the present invention, the object is based, to create a novel coolant pump that is easy can be switched on and off.
Diese Aufgabe wird durch eine Kühlmittelpumpe gemäß Anspruch 1 gelöst. Erfindungsgemäß weist die Antriebswelle ein mit der Antriebsscheibe fest verbundenes erstes Antriebswellensegment und ein mit einem Laufrad der Kühlmittelpumpe fest verbundenes zweites Antriebswellensegment auf, wobei zwischen das erste Antriebswellensegment und das zweite Antriebswellensegment ein in Axialrichtung der Antriebswelle verschiebbares Betätigungselement für Klemmkörper geschaltet ist, und wobei abhängig von der axialen Relativposition zwischen dem axial verschiebbaren Betätigungselement und den beiden axial unverschiebbaren Antriebswellensegmenten eine Antriebsverbindung zwischen den Antriebswellensegmenten über die Klemmkörper hergestellt oder aufgelöst ist.These Task is achieved by a coolant pump according to claim 1 solved. According to the invention, the drive shaft a fixedly connected to the drive pulley first drive shaft segment and a fixedly connected to an impeller of the coolant pump second drive shaft segment, wherein between the first drive shaft segment and the second drive shaft segment in the axial direction of the drive shaft sliding actuator for clamping body is switched, and wherein depending on the axial relative position between the axially displaceable actuator and the two axially immovable drive shaft segments a drive connection between the drive shaft segments via the clamp body is prepared or dissolved.
Mit der hier vorliegenden Erfindung wird vorgeschlagen, die Antriebswelle der Kühlmittelpumpe in zwei Segmente zu untergliedern, nämlich in ein erstes Antriebswellensegment, welches fest mit der Antriebsscheibe verbunden ist, und ein zweites Antriebswellensegment, welches fest mit dem Laufrad der Kühlmittelpumpe verbunden ist.With the present invention is proposed, the drive shaft to divide the coolant pump into two segments, namely in a first drive shaft segment, which firmly is connected to the drive pulley, and a second drive shaft segment, which is firmly connected to the impeller of the coolant pump is.
Zwischen das erste Antriebswellensegment und das zweite Antriebswellensegment ist ein in Axialrichtung der Antriebswelle verschiebbares Betätigungselement für Klemmkörper geschaltet. Abhängig von der axialen Relativposition zwischen dem Betätigungselement und den Antriebswellensegmenten ist entweder eine Antriebsverbindung zwischen den Antriebswellensegmenten hergestellt oder aufgelöst. Die Klemmkörper dienen dabei der Kraftübertragung bzw. Momentübertragung zwischen den Antriebswellensegmenten.Between the first drive shaft segment and the second drive shaft segment is a displaceable in the axial direction of the drive shaft actuator switched for clamping body. Dependent from the axial relative position between the actuator and the drive shaft segments is either a drive connection made or dissolved between the drive shaft segments. The Clamps serve the power transmission or Moment transmission between the drive shaft segments.
