Bogie for high-speed rail vehicles - incorporates torsion frame with rigid corners and two rigid longitudinal supports

摘要

The two rigid longitudinal supports may be moved relative to each other in a vertical direction, but are not moveable in a horizontal plane. The supports are connected via elastic wear-resisting units and the bogie has a pivot point with the vehicle body, and a guide at each axle bearing. A wear-resisting unit (5) connecting the centres of the longitudinal bogie supports (3) is combined with similar units (6), retaining the support ends. The wear-resistant unit (5) located in the vertical cross central plane is formed as a centre link (36), allowing movement only about the y-axis. The end units (6) are part of a horizontal spring plates (35), which form head sections of the bogie frame.
