Abstract
(DE)
Die Erfindung betrifft eine elektrische Kühlmittelpumpe (1) zur Kühlung von Batteriepacks eines batteriebetriebenen Kraftfahrzeuges aufweisend einen Elektromotor (11) mit einer Welle (10), wobei die elektrische Kühlmittelpumpe (1) eine Schraubenspindelpumpe (2) mit einer Antriebsspindel (4) und wenigstens einer Nebenläuferspindel (5) aufweist, und wobei die Antriebsspindel (4) mit der Welle des Elektromotors (10) drehfest verbunden ist.
(EN)
The invention relates to an electrical coolant pump (1) for cooling battery packs of a battery-driven motor vehicle, comprising an electric motor (11) with a shaft (10), wherein said electrical coolant pump (1) comprises a screw pump (2) having a driving screw (4) and at least one secondary rotor screw (5), and the driving screw (4) is secured, for conjoint rotation, to the shaft of the electric motor (10).
(FR)
L’invention concerne une pompe à agent de refroidissement électrique (1) destiné à refroidir les batteries d’un véhicule automobile fonctionnant sur batteries et comprenant un moteur électrique (11) pourvu d’un arbre (10). La pompe à agent de refroidissement électrique (1) comporte une pompe à vis (2) pourvue d’une broche d’entraînement (4) et d’au moins une broche de rotor secondaire (5) et la broche d’entraînement (4) est reliée solidairement en rotation à l’arbre du moteur électrique (10).
