Abstract: A method and device for tilting a car body of a vehicle in a trackbound train when the train passes through a track curve. The respective vehicles in the train comprise bogies supporting a car body resting thereon, includes devices for tilting the car body in relation to the bogies, for indicating a track curve, and a control system for controlling the tilting of the car body in dependence on the geometry of the track curve. The position of the train along a route is determined point-by-point by the train being equipped with devices for detecting its position and by registering the curve geometry of the track when the train runs over a track section from the determined position, and storing it in real time as a sequence of measured values describing the curve geometry of the track section in an electronic memory. The curve-geometry data about the track section, previously stored in the memory is used for controlling the tilting of the car body during the next passage through curves within the track section.

Abstract: The invention relates to a self-steering single-axle bogie for trackbound vehicles comprising one single wheel set (8) and wherein each wheel (8a, 8b) is rigidly connected to an intermediate wheel axle (14), wherein the wheel set (8) is attached rigidly or by means of springs (10) to a bogie frame (2), which is rotatably arranged around a vertical axis. Further, the bogie is joined to the car body (4) of the vehicle via at least one toggle link (16) extending in the longitudinal direction of the vehicle and preventing the bogie from tilting, or nodding, in the vertical longitudinal plane through the vehicle. The wheels (8a, 8b) exhibit conical or saddle-shaped treads (18), with an elevated conicity at least in the tread (18) nearest the wheel flange, the wheel set (8) being guided into approximate radial alignment in the track through the combined effect of the conicity of the wheels (8a, 8b) in the tread (18) and the frictional forces which act between wheels (8a, 8b) and rails (20a, 20b).
