Mechatronic systems for active steering and running gear control in principle offer an enormous potential for enhancements regarding this list of demands, so that we are developing a concept for a novel mechatronic running gear, see figure below.
Unit with carrier and independently torque-controlled wheels for the mechatronic running gear.
Its major components are the feedback-controlled single wheels and the wheel carrier, which may be aligned along a curve radius. The wheel drives serve two purposes, they are responsible for traction and lateral motion of the wheel pair. This way the carrier-wheels-unit may be adjusted to the middle of the track and may be steered into curves so that low-wear and -noise running characteristics are achieved.
A particular challenge of this project is to find an appropriate sensor concept that is reliable in daily train operation.
In the first step it is planned to design and to realise a first scaled prototype, so that advantages and disadvantages of the concept can be evaluated using the roller rig at our institute, see figure below.
Beside the application to high-speed trains, we also see a high potential of the concept even for urban transport systems, where low-floor, low-noise and low-wear characteristics are highly relevant as well.
