The invention is based on the combination of the following features: 1. The connector rod which controls the upper arm of the pantograph is located above the lower arm of the pantograph. As a result, the current collector is approximately 150 mm lower in the pulled-off state. 2. The spring-mounting plane of the spring-mounting system of the bow contact is turned through approximately 90 DEG . As a result, the high prestressing of the suspension system by the flow pressure of the slipstream is eliminated. 3. The convex, downwardly directed bead of the fitting of the carbon slider bar of the bow contact is of rectangular design. As a result, a damaging increase in the contact pressure on the contact wire at high travel speeds is avoided. 4. The risk of the two individually sprung slider bars of the bow being tilted by the pressure of the slipstream is avoided by both slider bars being connected to one another at their ends by means of rigid connections which have no axis of rotation. If one of the four constructional features is omitted, the operational quality of the entire current collector for high speeds would be substantially reduced to the point of becoming unusable. |
