Abstract
A self-steering system for a radial bogie of a railroad vehicle is provided. The self-steering system includes a plurality of links which connect the leading and trailing wheelsets to the bogie frame. Each of the links is adapted to provide a smaller degree of movement between the link and the wheelset at one end and a larger degree of movement between the link and the bogie frame at the other end.
