Wheel set guidance assembly

A bogie comprising a wheel set guidance assembly for connecting a wheel set to a bogie frame, comprising individual vertical lateral and longitudinal guidance elements for independent guidance of the movement of the wheel set in vertical, lateral and longitudinal directions wherein the stiffness of each guidance element can be selected independently of the other guidance elements, and wherein the longitudinal guidance element is a longitudinally arranged wheel set linkage bar for connecting the bogie frame and a wheel set bearing flexibly to allow guidance of a turning movement of the wheel set on curved tracks.

A method for providing a bogie with wheel set guidance comprising the steps of:

• providing a bogie comprising a wheel set guidance assembly comprising individual vertical, lateral and longitudinal guidance elements and
• selecting the stiffness of each guidance element in vertical, lateral and longitudinal directions independently of the stiffness of the other guidance elements to optimise the wheel set guidance in view of the requirements of a particular application of the bogie.
