Bow for pantograph fixed on roof of train to collect electric current circulating in airline, has driving unit driving movable contact strips in orthogonal displacement so as to separate movable contact strips from fixed contact strip

摘要

The bow (300) has movable contact strips (28, 29) and a fixed contact strip (27), where the movable contact strips are moved transversely to the fixed contact strip from a position to another position according to a circular translatory movement compared to the fixed contact strip. A driving unit drives the movable contact strips in an orthogonal displacement during the transverse displacement of the mobile contact strips so as to separate the movable contact strips from the fixed contact strip, where the orthogonal displacement of the mobile contact strips is a longitudinal displacement.
