<p>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).</p> |
