Colector de corriente (pantógrafo) con mayor ángulo de rotación


Oferta Tecnológica
Un equipo de científicos de una universidad polaca ha desarrollado un nuevo colector de corriente para trolebuses, camiones eléctricos y otros vehículos de carretera con catenaria. Este colector tiene la capacidad de rotar en posición perpendicular (hasta 90º) al eje del vehículo eléctrico, lo que mejora la capacidad de maniobra. El pantógrafo se emplea en vehículos para transporte público, transporte de mercancías y personas de larga distancia o incluso minas, puertos y zonas de construcción. El equipo de científicos busca socios en los sectores de automoción o transporte interesados en incorporar la tecnología en sus productos y establecer acuerdos de licencia.


Current collector (pantograph) with increased rotation angle is offered under license agreement
A team of scientists from Poland has developed a new construction of current collector for trolleybuses, electric trucks and other overhead line-powered road vehicles. The offered collector can rotate to perpendicular position (make 90-degree turn) in relation to the axis of a vehicle, thus increasing its manoeuvrability. The innovation consistent with the idea of smart cities is offered under license agreement.
Motor vehicles and mass road transportation (of people and goods) have become features of developed societies and global economy. Drawbacks of that popularity are road congestion and air pollution, as most vehicles are powered by fossil fuels. Particulate matter, lead, sulphur dioxide and many other dangerous substances emitted to the atmosphere are sources of serious health and environmental concerns (e.g. climate changes). In order to combat those problems, the EU has been promoting the idea of clean, sustainable and smart cities.

Automotive industry and road transportation sector have been adapting to the policies and kerbing greenhouse gases (GHGs) emissions by i.a. substituting combustion engines with electric ones. The arising technological challenge is to find an effective method of powering them. Batteries have limited capacity and, as a result, limited range. Whereas that may not be prohibitive for private transportation, it is a barrier for a public and freight transport, where vehicles have to travel long distances and engines have to work continuously over extended periods of time. A solution more suitable for commercial transportation is to connect road vehicles to an electric grid (overhead lines), similarly to trains or trams. In 2012 Siemens has even presented their concept of such an electric motorway and truck. A problem with that approach is vehicles´ limited ability to change road lines and avoid various obstructions - constraints of available current collectors (pantographs) force them to travel almost directly under overhead lines, with little room for deviation.

A team of scientist from a university located in the North-West Poland has found and is offering a solution to the problem of limited manoeuvrability of overhead line-powered road vehicles. They have designed a new pantograph that, unlike its competitors, can make a turn of up to 90 degrees and be positioned perpendicularly to the axis of an electric vehicle. As a result, an overhead line-powered road vehicle will be capable of changing road lines and avoiding various obstructions. The offered current collector is a rotating beam that is attached to a vehicle´s cabin at the bottom and connected via a joint with a plate and two strands at the top.

The scientists are offering their invention under licensing agreement. They are interested in cooperation with companies from automotive industry or transportation sector that will introduce the technology into their products. The offered pantograph can be used in overhead line-powered road vehicles employed in public transportation, for long-haul shipments of goods/people or even utilised at a single site such as a mine, a port, a building site.
Advantages and Innovations:
The innovation increases a manoeuvrability of overhead line-powered road vehicles and allows them to change road lines. As a result, it is possible to:
· position vehicle away from an electric traction so that nothing gets caught on it during re-/unloading;
· avoid various road obstructions and use a full width of a road.

The invention allows for a further market growth of electric cars by addressing concerns that so far have deterred commercial users from buying such vehicles. As such, offered technology is consistent with the idea of smart cities and beneficial:
· financially - electric vehicles are cheaper in exploitation than the ones powered by fossil fuels;
· environmentally and for human health - electric vehicles emit far fewer GHGs and other harmful substances than the ones powered by fossil fuels.
