    Abstract: A device (1) for adjusting the bearing force of a pantograph (30) of a railroad train set (10) on a catenary wire (2). The pantograph (30) has, at its upper end, a bow (3) in mechanical and electrical contact with the catenary wire (2), connected mechanically to an actuator (7, 34) exerting a nominal force on it at predetermined points and in a predetermined direction. A device (31) measures the contact force between the bow (3) of the pantograph (300 and the catenary wire (2) supplies information relating to the measured force. A transmitter (5, 4a) transmits the measurement information from the measuring device (31, 40) into an appropriate zone of the railroad train set (10). A processor (60, 20) processes the transmitted information and set-point range signals and supplies logical control signals. The actuator (6, 7) is controlled from the logical control signals when the measured contact force exceeds a predetermined maximum force threshold (Smax) or in responses to predetermined external control signals.

    Abstract: A drive system for raising or lowering a sliding piece of a current collector for rail vehicles. The sliding piece is disposed on a positioning device of the current collector, and the sliding piece is configured to be brought into contact with an overhead line using contact pressure. The drive system includes a bellows drive which is actuated by compressed air to actuate the positioning device, and a pneumatic control unit having a control valve for supplying or withdrawing compressed air to/from the bellows drive. The drive system includes a detection line and a lowering valve for venting the bellows drive when pressure drops in the detection line, the lowering valve being a 3/2-way valve disposed in a pneumatic supply line between the control valve and the bellows drive.

    Abstract: This rapid descent device comprises a valve comprising two chambers, at least one rub strip fastened to the body of the current-collector bow of the pantograph, intended to come into contact with the overhead wire and equipped with degradation detection circuit, at least one supply line of fluid to the main chamber of the valve, at least one feed line intended to feed this fluid to the pilot chamber of the valve, as well as at least one detection line extending from the pilot chamber of the valve, to feed a respective detection circuit.
    The rapid descent device comprises means for temporary shut out of the feeding of fluid of the main chamber, which reliably ensures the initial raising of the pantograph until the pantograph comes into contact with the overhead wire.
