Abstract

Track systems, in particular those having plane tracks (roadways), require in winter measures to keep the functional surfaces of the wheel/track interface free of ice. Traditionally, this is done using stationary track-surface heating means. In contrast, it is proposed according to the invention to keep these tracks free from hoar-frost, ice and snow by means of high-energy heating units mounted on the vehicle.

Description

Moderne Personentransportsysteme, wie beispielsweise People-Mover-Systeme, die nicht auf herkömmlichen Schienen fahren, benutzen vorzugsweise flächige Fahr wege aus Beton oder Stahl. In Regionen, wo klimatisch be dingt Reifglätte, Eis oder Schnee auftreten kann, ist es erforderlich die Fahrwege zu beheizen, um sichere Be triebszustände, insbesondere bezüglich der spezi fizierten Bremsverzögerung, zu erhalten. Herkömmliche Fahrweg/Fahrbahn Beheizungssysteme arbeiten mit in die Fahrbahn eingelagerten stromgespeisten Heizkabeln oder mit eingelagerten Rohrsystemen, durch die erwärmte Flüssigkeit oder Dampf zirkuliert. Neben den hohen Investitionskosten, ist der Energiebedarf für diese Systeme beträchtlich und beträgt in vielen Fällen über 70% der Gesamtenergiekosten eines Systems bei Winter betrieb. Außerdem sind je nach Tarifgefüge der Länder u. U. wegen der hohen Anschlußwerte beträchtliche Ener giebereitstellungskosten zu zahlen.Modern passenger transportation systems, such as People-mover systems that are not based on conventional ones Drive rails, preferably use flat driving paths made of concrete or steel. In regions where climatic conditions due to frostiness, ice or snow, it is required to heat the routes to ensure safe loading drive states, especially with regard to the speci get braking deceleration. Conventional Track / lane heating systems work in the Road-fed power-fed heating cables or with embedded pipe systems through which heated Liquid or vapor circulates. In addition to the high Investment cost is the energy requirement for this Systems considerable and in many cases is over 70% of the total energy costs of a system in winter business. In addition, depending on the tariff structure of the countries u. Considerable energy due to the high connection values to pay for the provisioning costs.

Die erfindungsgemäße Lösung sieht demgegenüber vor, die Fahrbahnoberflächen und auch Stromschienen sowie Signal leitungen durch an den Fahrzeugen entsprechend ange brachten Hochleistungsheizeinheiten reif-, eis- und schneefrei zu halten. Wobei es aber auch durchaus er forderlich sein kann, bei starkem Schneefall den Fahrweg erst mechanisch durch einen fahrzeugseitigen Schneepflug zu räumen. Diese Hochleistungsheizeinheit kann beispiels weise ein Heizgerät sein, das auf Microwellenbasis, mit Infrarot oder einem ähnlichen Strahlungsprinzip arbeitet. Durch eine entsprechende Anordnung im Unterbodenbereich der Fahrzeuge, dicht über der Fahrbahndecke oder an den Strom- und Signalschienen geführt, ermöglicht dies ggf. bei reduzierter Fahrgeschwindigkeit ein Abtauen des Belages von der Fahrbahnoberfläche.In contrast, the solution according to the invention provides that Road surfaces and also power rails and signal cables through accordingly on the vehicles brought high-performance heating units mature, ice and keep snow-free. But it is also quite he can be necessary in heavy snowfall the road only mechanically by means of a snow plow on the vehicle to vacate. This high-performance heating unit can, for example wise be a heater based on microwaves Infrared or a similar radiation principle works. Through an appropriate arrangement in the underbody area of the vehicles, just above the road surface or at the Guided by current and signal rails, this may be possible defrosting at reduced speed Of the road surface.

Mit diesem Heizsystem kann eine wirkungsvolle, bedarfsge rechte und sichere Beheizung der entsprechenden Ober flächen zur Abschmelzung des Reif-, Eis- oder Schnee belags erfolgen. Damit verbunden sind erhebliche Einspa rungen bei den Investitions- und Energiekosten.With this heating system, an effective, needs-based right and safe heating of the corresponding waiter areas for melting frost, ice or snow coverings. This entails considerable savings investment and energy costs.

Claims
