Abstract

Ein erfindungsgemässer Oberleitungsbus umfasst einen Stromabnehmer (11) zur Kontaktierung einer Gleichstrom führenden Oberleitung, mindestens einen Antriebsmotor (52, 57) zum Antreiben einer Antriebsachse, eine Stromversorgung zur Versorgung des mindestens einen Antriebsmotors (52, 57) mit Antriebsstrom und einen Hochleistungs-Energiespeicher (41, 42) zur Zwischenspeicherung von über den Stromabnehmer (11) aufgenommener elektrischer Energie. Die Stromversorgung umfasst einen Trenntransformator, der einen ersten, mit dem Stromabnehmer (11) verbundenen Abschnitt der Stromversorgung von einem zweiten Abschnitt der Stromversorgung galvanisch trennt, wobei der mindestens eine Antriebsmotor (52, 57) und der Hochleistungs-Energiespeicher (41, 42) im zweiten Abschnitt angeordnet sind. Durch die galvanische Trennung werden im zweiten Abschnitt der Stromversorgung die üblichen Spannungsspitzen vermieden. Entsprechend können elektrische Komponenten im zweiten Abschnitt, z. B. Umrichter, einfacher und damit leichter und kompakter aufgebaut werden. Ferner wird die Verwendung von flüssigkeitsgekühlten Komponenten ermöglicht. Entsprechend umfasst der Oberleitungsbus einen flüssigkeitsgekühlten Permanentmagnetmotor (52, 57).An overhead trolley bus according to the invention comprises a current collector (11) for contacting a direct current overhead line, at least one drive motor (52, 57) for driving a drive axle, a power supply for supplying the at least one drive motor (52, 57) with drive current and a high-power energy store ( 41, 42) for temporarily storing electrical energy absorbed via the current collector (11). The power supply comprises an isolating transformer which electrically isolates a first portion of the power supply connected to the current collector (11) from a second portion of the power supply, the at least one drive motor (52, 57) and the high power energy store (41, 42) in second section are arranged. The galvanic isolation avoids the usual voltage peaks in the second section of the power supply. Accordingly, electrical components in the second section, z. As converters, simpler and thus lighter and more compact. Furthermore, the use of liquid-cooled components is made possible. Accordingly, the trolleybus comprises a liquid-cooled permanent magnet motor (52, 57).
