Abstract: A device for collecting electric current for a rail vehicle that tilts. The rail vehicle includes a car body having a roof and a bogie beneath the car body. The bogie has a bogie frame and a bolster above the bogie frame and the car body is supported on the bolster. The bolster tilts around an axis with respect to the bogie frame upon tilting of the body. The collecting device includes a platform supported on the roof of the car which is movable transversely to the vehicle access. A pantograph supported on the platform, a flexible connection between the bogie and the pantograph for moving the platform on the pantograph transversely with tilting of the bogie frame, but for not moving the platform along with tilting of the bogie bolster. A motion reducing and amplifying mechanism between the platform and the flexible connection.

Abstract: The position detector system for guided vehicles has a memory block which stores each journey, divided into sections identified by their theoretical parameters and in which the correction curves are stored; at least one recording unit sensitive to travel in a curve and a relative position recording unit, signals from which are sent to a control unit which using the signals, establishes the profile of variations of the actual parameters of the correction curves and carried out an adjustment based upon achievement of the minimum error in the profiles of coordinates obtained from the theoretical parameters and the actual parameters, determining the absolute real position of the vehicle. The system is especially suited for the railway rolling stock industry.
