Title
(EN) DRIVING ARRANGEMENT FOR CONSTRUCTION MACHINE
(FR) AGENCEMENT D'ENTRAÎNEMENT DESTINÉ À UN ENGIN DE CHANTIER
Abstract
(EN)
A driving arrangement (1) for a construction machine, preferably for an excavator, comprising a hydraulic pump (2) for powering a working equipment and/or locomotion of the construction machine through a hydraulic circuit, an electric motor (3) for driving the hydraulic pump, wherein power of the electric motor is transferable to the hydraulic pump via a connection means (7), a supporting device (8) for mounting the driving arrangement to the construction machine, the supporting device supporting the hydraulic pump and the electric motor, and an adjustment mechanism for adjusting the positional relationship between the electric motor and the hydraulic pump to align both component with respect to each other.
(FR)
L'invention concerne un agencement d'entraînement (1) destiné à un engin de chantier, de préférence une excavatrice, comprenant une pompe hydraulique (2) destinée à alimenter un équipement de travail et/ou une locomotion de l'engin de chantier par l'intermédiaire d'un circuit hydraulique, un moteur électrique (3) destiné à entraîner la pompe hydraulique, la puissance du moteur électrique pouvant être transférée à la pompe hydraulique par l'intermédiaire d'un moyen de couplage (7), un dispositif de support (8) destiné à monter l'agencement d'entraînement sur l'engin de chantier, le dispositif de support supportant la pompe hydraulique et le moteur électrique, et un mécanisme de réglage destiné à ajuster la relation de position entre le moteur électrique et la pompe hydraulique afin d'aligner les deux composants l'un par rapport à l'autre.
