Abstract
A truck for a railway vehicle has a truck frame with four individual wheels, which are mounted so that they can rotate around horizontal axles, and whereby one wheel pair is driven. To be able to negotiate tight curves with minimal wear, maximum safety and low construction costs, and to be able to achieve higher speeds on straight segments of track, the driven wheel pair can be steered radially with respect to the curve around a common vertical axis as a function of a setpoint determined by a sensor system, while the non-driven individual wheels are combined into a self-steering individual wheel module so that they can each pivot around their own vertical axes, and can be coupled together so that they are synchronized by means of a steering device.
