Voith presents its latest developments at this year's InnoTrans in Berlin. Visitors to stand 220 in hall 1.2 will learn about the company's innovative, reliable drive components, couplers and service concepts, as well as getting a look at its lightweight products, including an energy absorber and a front nose for Germany's new ICx high-speed train.
While 'service' used mainly to be associated with repairs and spare parts, Voith's modern interpretation of the term means exactly the opposite. It includes just-in-time schemes with overhauls within a precisely defined window, or preventive overhauls, as well as exchange pools for transmissions and Scharfenberg couplers.
Voith goes a step further in terms of systems service. Based in Kiel, Germany, the firm carries out major overhauls of entire vehicles. In future, the site will offer the removing and reinstalling of complete bogies within one day, for example. Chassis are overhauled while the operator's vehicle goes back into the rails with a serviced exchange unit.
Whether monitoring, documenting or informing - and, where necessary, maintaining or modernising - Voith's proven competence enables it to focus on integrated rolling stock management. The all-inclusive scheme keeps operators' services running, while freeing them from all vehicle-related endeavours. As a further service the company offers to combine overhaul periods with upgrading drive components to the latest technical specifications, repairing damaged vehicles, or integrating new systems into infrastructures.
Such product improvements are at the very heart of Voith's modern service concept and apply to components and entire systems alike. This is demonstrated at InnoTrans by a start-stop automatic exhibit. The system can be retrofitted to older vehicles, even if they are not fitted with electronic control systems. It reduces engine operating hours, thereby cutting maintenance costs, emissions and fuel consumption. Voith not only offers the components for systems, but also installs and approves them, under one roof.
At this year's InnoTrans Voith presents a new energy absorber made of glass-fibre-reinforced plastics (GFRP) as a part of its lightweight Galea concept. As well as a fibre-composite crash tube the absorber features a bearing and an anti-climb plate, both made from aluminium. The components boast excellent longevity and constant energy absorption, even when the absorbers meet at an offset.
The weight, at 70-95kg, is potentially 60% lighter than standard steel absorbers, meaning higher economic efficiency and a saving of resources, while providing at least the same level of safety.
Voith underlines its systems philosophy further with the RailPack, a PowerPack for diesel setups that can be fitted with hydrodynamic, electric and hydromechanical drives. The version on show in Berlin features the hydrodynamic S111 transmission for rail applications in the power range up to 250kW.
Its robust technology enables it to cope with all operating and weather conditions and requires only little maintenance. Combined with long oil-change intervals, this ensures continuously low operating costs.
A further installation option will be shown in the shape of Voith's hydromechanical DIWARail transmission, in which a hydrodynamic brake significantly minimises wear. Thanks to its parallel-shaft reversing transmission, reversing on the gear unit is no longer required. This reduces the mass of the gear unit, thereby reducing fatigue and improving running properties. Being towed with the engine switched off is also possible.
