Wiper for current pick-up for electric locomotive

摘要

The wiper has two slider parts (1) arranged parallel to the direction of movement and joined by a frame (2). A guide construction movably connects the frame to the apex structure (6,7) of the pick-up. A spring (14,14') supported by the apex structure presses the slider parts against the drive wire (9). The guide construction is formed by linkage elements(4,4') separated by the spring and mounted pivotably on the apex structure and on the frame via elastically flexible bearing bushes.
