Track bearer for vehicles on tracks, especially magnetic levitation vehicles, has arrangement for varying lower part temperature when temperature variations, especially of upper part, occur

摘要

The device (1) has a closed cross-section of lateral longitudinal bearer struts, floor plate and a top plate and fitting parts for functional surfaces on laterally protruding parts. There is an arrangement for varying the temperature of the lower part (8) when temperature variations, especially of the upper part (7), occur as a result of external influences so that the temperature difference between the upper and lower parts is minimal.
