Framework for a rail vehicle has a main framework with a main cross strut and a subsidiary cross strut, both interlinked via a sole bar

摘要

A main framework (2) has a main cross strut (MCS) (4) and a subsidiary cross strut (SCS) (5), both interlinked via a sole bar (SB) (6), which has first (7.1) and second (7.2) SB elements with no gaps in a lengthwise direction between the MCS and SCS. An indirect link between the SB and the SCS is achieved with low flexural strength and a transfer in rigidity adapted to the flexural strength.
