Abstract

Die Erfindung betrifft eine Kühlmittelpumpe zur Förderung eines Kühlmittels. Die Pumpe umfasst eine Pumpeneinheit mit einem Pumpenrad (01) sowie einer Pumpkammer (03) mit Sauganschluss (04) und Druckanschluss (06); und eine Antriebseinheit, die einen elektromotorischen Direktantrieb aufweist, welcher eine Aktiveinheit mit einer elektrischen Wicklung als Stator (08) sowie eine Passiveinheit als Rotor (07) besitzt. Der als Außenläufer gestaltete Rotor (07) ist innerhalb und der Stator (08) ist außerhalb der Pumpeneinheit angeordnet. Rotor (07) und Stator (08) sind zylinderförmig ausgebildet und unter Belassung eines axial verlaufenden Luftspalts (12) konzentrisch zueinander angeordnet. Der Luftspalt (12) wird vom Kühlmittel durchströmt. Das Pumpenrad (01) ist am Rotor (07) axial mit dessen Drehachse (16) ausgerichtet befestigt. Der Rotor (07) erstreckt sich in einer Rotorhülse (13), welche sich an die Pumpkammer (03) anschließt. Der Stator (08) ist in einer Statorhülse (14) angeordnet, welche konzentrisch innerhalb der Rotorhülse (13) positioniert und gegenüber dieser abgedichtet ist.
