PURPOSE: To prevent the current collecting heads of a pantograph for an electrically driven track vehicle from being separated from an overhead wire. CONSTITUTION: The pantograph of an electrically driven track vehicle for current collection is provided with an upper arm 5 whose end is provided with a support 22. Two current collecting heads 20 provided with a wear strip 19 for electrical connection to an overhead wire L are coupled with the support 22 by means of coupling means 23, 24, 25, 28, and 30, and these coupling means are so adjusted that they guide the heads in movement in the lateral direction relative to the electric wire and in the direction perpendicular to the plane of the track and, when one of the heads 20 is moved relative to the support 22, force in the opposite direction is exerted on the other head 20. |
