Title (EN) DUAL PUMP GROUP WITH MECHANICAL DRIVE COMPRISING A CENTRIFUGAL CLUTCH
(FR) GROUPE DE POMPES DOUBLE À ENTRAÎNEMENT MÉCANIQUE COMPRENANT UN EMBRAYAGE CENTRIFUGE
Abstract:
(EN) A pump group (1) for a cooling system of an engine of a vehicle, of the dual type. The pump group (1) comprises an impeller (3) mounted on a shaft (2) that is commandable in rotation by an electric drive (5) and a mechanical drive (10). Said mechanical drive (10) comprises: a rotating member (11), that is commandable in rotation by mechanical movement means comprised in the vehicle; a rotary drum (12), operatively connected to the shaft (2); a centrifugal clutch device (15) comprising: m) a central body (151) integrally attached to the rotating member (11); n) a plurality of engagement elements (152) movably fixed on the central body (151) suitable to translate in a radial direction with respect to the axis (X-X) to engage the rotary drum (12).
(FR) L'invention concerne un groupe de pompes (1) de type double pour un système de refroidissement d'un moteur d'un véhicule. Le groupe de pompes (1) comprend une roue (3) montée sur un arbre (2) qui est commandé en rotation par un entraînement électrique (5) et un entraînement mécanique (10). L'entraînement mécanique (10) comprend: un élément rotatif (11), qui est commandé en rotation par des moyens de déplacement mécanique compris dans le véhicule; un tambour rotatif (12), relié de manière fonctionnelle à l'arbre (2); un dispositif d'embrayage centrifuge (15) comprenant: m) un corps central (151) fixé d'un seul tenant à l'élément rotatif (11); n) une pluralité d'éléments de mise en prise (152) fixés de façon mobile sur le corps central (151) et appropriés pour effectuer une translation dans une direction radiale par rapport à l'axe (X-X) pour venir en prise avec le tambour rotatif (12).
