Abstract:
Designs for a battery-powered, all-electric locomotive and related locomotive and train configurations are disclosed. In one particular exemplary embodiment, a locomotive may be driven by a plurality of traction motors powered exclusively by a battery assembly which preferably comprises rechargeable batteries or other energy storage means. The locomotive carries no internal combustion engine on board and receives no power during operation from any power source external to the locomotive. A battery management system monitors and equalizes the batteries to maintain a desired state of charge (SOC) and depth of discharge (DOD) for each battery. A brake system may be configured to prioritize a regenerative braking mechanism over an air braking mechanism so that substantial brake energy can be recovered to recharge the battery assembly. Many locomotive or train configurations involving battery-powered or battery-toting locomotive(s) may be implemented.
Abstract:
The invention relates to a method and device for the transport of goods by rail, wherein goods wagons are used with independent propulsion means. The propulsion means for the goods wagons are used only for short journeys from a station to a customer and back. For long journeys the goods wagons are assembled into a train and pulled by a tractor vehicle.
Abstract:
An emergency power generating unit (2), comprising a gas turbine (23) to supply a train on-board systems in the event of a failure of the main electrical power supply. Specifically the power generated by the turbine is used to run an electrical energy generator (29) for powering an air conditioning system (77).
Abstract:
The invention relates to an electric energy supply system for a train or several trains (1), comprising drive units (2) for a first voltage system with a predetermined voltage form and voltage level, whereby at least one separate energy saving vehicle (3) is mechanically and electrically coupled to the train or several trains (1) having a unit (4, 7) for tapping and converting electric energy from at least one second voltage system having a predetermined voltage form and voltage level into electric energy of the first voltage system.
Abstract:
The invention concerns a method of producing a locomotive having a locomotive housing wherein the housing side walls also have a supporting function, according to the basic principles of lightweight construction. The mechanical equipment (9) is inserted into the locomotive housing (1) via roof openings and is mounted on the locomotive bogie (2). According to the invention, in order to avoid constricted spaces with this type of assembly and to be able to assemble the entire, or substantial parts of, the mechanical equipment (9) as an integral component, the mechanical equipment (9) is first assembled on the locomotive bogie (2) and the side walls are built on as a supporting structure in subsequent production and assembly steps by securing roof crossbeams (3), each consisting of two perpendicular supports (4) and a transverse hoop (6), on the locomotive bogie (2) at parallel spacings. Surface components (7) of preferably fibre-reinforced plastics are then inserted between the supports (4) of two adjacent roof crossbeams (3) and connected, preferably bonded, to form a supporting side wall structure.
Abstract:
Die Erfindung bezieht sich auf ein Fahrzeug, insbesondere Schienenfahrzeug (10), mit einem einen oder mehrere elektrische Motoren (21, 22) aufweisenden Antrieb (20) und einer mit dem Antrieb (20) in Verbindung stehenden und diesen ansteuernden Antriebssteuereinrichtung. Erfindungsgemäß ist vorgesehen, dass das Fahrzeug zusätzlich zu der Antriebssteuereinrichtung eine Überwachungseinrichtung (50) aufweist, die unabhängig von der Antriebssteuereinrichtung arbeitet, wobei die Überwachungseinrichtung (50) derart ausgestaltet ist, dass sie den Antriebsstrom des Antriebs (20) quantitativ erfasst und den Antrieb (20) abschaltet, wenn zumindest eine Antriebsausschaltbedingung erfüllt ist und gleichzeitig ein den Antriebsstrom angebender Antriebsstrommesswert (Ma) einen aktiven Antriebsbetrieb des Antriebs (20) anzeigt.
Abstract:
A dynamic linear motor is controlled by determining a relative proximity of a moving rotor of the linear motor to a fixed stator segment of the linear motor using a current location of the moving rotor. A current driving characteristic of the linear motor at the current location of the moving rotor is determined. Settings for the fixed stator segment when the moving rotor reaches the fixed stator segment are identified based on the current driving characteristic. The fixed stator segment is driven based on the settings when the moving rotor reaches the fixed stator segment.
