Abstract:
A protection arrangement (1) for a current collector (3, 10) arranged on a vehicle (20) having a rechargeable energy storage (23), where the protection arrangement (1) comprises a first protective state (4) in which the current collector (3, 10) is covered by the protection arrangement (1) and a second open state (5) in which the protection arrangement (1) allows contact between the current collector (3, 10) and a corresponding current supply means (6) during charging of the energy storage and where the protection arrangement (1) is automatically opened from the protective state (4) to the open state (5) when the vehicle has reached a predefined charging position. The advantage of the invention is that a current collector can be enclosed when the vehicle is not charged and that the protection arrangement opens automatically when a charging position is reached. This improves the safety of the vehicle and obviates the need of a specific circuit breaker that can disconnect the current collector from the electric energy storage. The charging of the vehicle is also simplified.
Abstract:
Die Erfindung betrifft ein Fahrzeug (10) mit einer Fahrerkabine (11) für einen Fahrer. Durch den Fahrer ist eine elektronisch gesteuerte Fahrzeugeinrichtung, insbesondere ein Stromabnehmer, bedienbar. Hierzu weist ein Bediengerät (30) Eingabemittel zur Eingabe eines Bedienbefehls durch den Fahrer und Ausgabemittel zur Ausgabe einer Zustandsmeldung an den Fahrer auf. Ein außerhalb der Fahrerkabine (11) angeordnetes Steuergerät (22) ist dazu eingerichtet, aus dem Bedienbefehl ein Steuersignal für die Fahrzeugeinrichtung und aus einem Zustandssignal der Fahrzeugeinrichtung die Zustandsmeldung zu erzeugen. Das Steuergerät (22) ist mit der Fahrzeugeinrichtung und dem Bediengerät (30) über ein Netzwerk (13) zur Datenübertragung verbunden. Das Bediengerät (30) ist tragbar ausgebildet, für eine Bedienung während der Fahrt in einer in der Fahrerkabine (11) angeordneten Haltevorrichtung (14) mit Netzwerkschnittstelle (15) festsetzbar und zur Mitführung durch den Fahrer aus der Haltevorrichtung (14) wieder lösbar.
Abstract:
A control device (26) for controlling a pressure delivered to a fluid-operated actuator (18) for actuating an electric current collector assembly (10) transmitting energy between an electrical line (20) and a vehicle (12) is provided with a fluidic circuit (24) comprising a pressure input (28) for connecting the fluidic circuit (24) to a pressure supply (22), a pressure output (29) for connecting the fluidic circuit (24) to the fluid-operated actuator (18), an electrically operated pressure regulator (44) for delivering a first regulated output pressure in response to an electrical set value, an second pressure regulator (46) for delivering a second regulated output pressure in response to a non-electrical set value, and selection means for detecting a specific condition and for selectively directing the air from the input to the output through the second pressure regulator when the specific condition is detected. The selection means comprise a directional control valve means (42) connected between the electrically operated pressure regulator (44), the second pressure regulator (46) and the pressure output (29).
Abstract:
Die Erfindung betrifft ein Verfahren zum Steuern einer Stromabnehmer-Konfiguration eines Zugverbandes (2; 42; 50) mit mehreren Stromabnehmern (28). Um Schäden an den Stromabnehmern (28) zu reduzieren/zu vermeiden, wird vorgeschlagen, dass eine von einer Fahrgeschwindigkeit des Zugverbandes (2; 42; 50) abhängige Zustandsgröße ermittelt wird und, nachdem ein vorgegebener Grenzwert von der Zustandsgröße in eine erste Richtung überschritten wird, zumindest einer der Stromabnehmer (28) während einer Fahrt des Zugverbandes (2; 42; 50) abgesenkt wird, sodass der Stromabnehmer (28) von einer Oberleitung (34), über die der Zugverband (2; 42; 50) mit Strom versorgt wird, elektrisch getrennt wird.
Abstract:
The invention relates to a method for controlling charging of an electric energy storage system (7) in a vehicle (1) comprising an electric machine (3) which is arranged for propulsion of said vehicle (1). The method comprises: initiating said charging upon connection of said energy storage system (7) to an external power supply (11) via a first connector element (9) associated with said vehicle (1) and a second connector element (10) associated with said external power supply (11); and monitoring a contact resistance defined by the connection of said connector elements (9, 10). Furthermore, the method comprises: measuring and calculating the power loss over said connector elements (9, 10) during said charging; and generating an error signal if said power loss is higher than a predetermined threshold value, said error signal being dependent on the magnitude of said power loss. The invention also relates to an arrangement for controlling charging of an electric energy storage system (7) in a vehicle (1).
Abstract:
The invention concerns a device for balancing a force comprising an articulated mechanism (10) consisting of a proximal arm (12) borne by a support wedged on a first hinge pin (20) and a distal arm (14) borne by the proximal arm and wedged on a second hinge pin (24) extending parallel to the first pin, the distal arm having a free end (26) supporting a load (F). The device further comprises first balancing means (18, 20) with high bandwidth acting on the proximal arm (12), second balancing means (18, 22) with high bandwidth acting on the distal arm (4), and co-ordinating means interposed between the first balancing means and the second balancing means to co-ordinate the respective rotational movements of the proximal arm and of the distal arm. The invention is applicable to mechanical manipulators, to transfer devices and to railway pantographs.
Abstract:
The invention relates to a vehicle (10) having a cab (11) for a driver. An electronically controlled vehicle device, in particular a current collector, can be operated by the driver. For this purpose, an operating device (30) has input means for the input of an operating command by the driver and output means for the output of a status indication to the driver. A control device (22) arranged outside the cab (11) is designed to produce a control signal for the vehicle device from the operating command and to produce the status indication from a status signal of the vehicle device. The control device (22) is connected to the vehicle device and the operating device (30) by means of a network (13) for the purpose of data transmission. The operating device (30) is designed to be portable, can be fixed in a retaining device (14), which has a network interface (15) and is arranged in the cab (11), for operation during travel, and can be detached from the retaining device (14) in order to be carried by the driver.
