The aim of the invention is to significantly reduce the construction space required for the current collector head and at the same time reduce noise emission and wear on the wearing strip. To this end, the rocker (4) consists of at least two single-piece angle levers (10) which are oriented parallel to the contact wire and arranged perpendicular to each other and which form an angle (8, 9) and have lever arms (8, 9) of different lengths. Said rectangular levers are each arranged in such a way that they can pivot about a common, fixed centre of rotation, against the force of a tension spring (12) of slight rigidity which acts approximately vertically on the shorter lever (9). The longer lever arm (8) presses directly against the wear strip arrangement and moves the latter in an approximately vertical direction on a part of a circular path with a very large diameter as it rises and falls. A hydraulic rotation damper (13) is located between the angle levers (10) and is actively connected to the same.
L'invention a pour objet de réduire considérablement l'encombrement de la tête du pantographe tout en réduisant l'usure de sa plaque d'usure et les émissions sonores. Pour ce faire, l'archet (4) est composé d'au moins deux leviers articulés (10) parallèles au fil de contact, formant un angle et constituant des bras (8, 9) qui sont réalisés d'une seule pièce, lesquels sont perpendiculaires l'un par rapport et de longueurs différentes. Ces leviers articulés (10) sont montés pivotants autour d'un pivot fixe commun respectivement à l'encontre d'un ressort de traction (12) de faible rigidité qui s'applique perpendiculairement sur le levier court (9). Le bras long (8) appuie directement sur le dispositif plaque d'usure et, lors du soulèvement et de l'abaissement, déplace ce dernier dans une direction approximativement verticale sur un segment de cercle de très grand diamètre. Un amortisseur rotatif (13) hydraulique, placé entre les leviers articulés (10), est en liaison active avec les leviers articulés.
