Patent ID: 7814841

Claim:
A rake of rail cars for passenger transport, the rake defining a travel plane and having two ends, the rake comprising: rake modules defining passenger compartments and being arranged in a row in a longitudinal line, the rake modules comprising carrier modules each provided with an assembly for support and guiding in a rail track, and connection devices each connecting two adjacent rake modules and comprising single-articulation connection devices each allowing relative rotation of the rake modules which the single-articulation connection device connects about one axis substantially perpendicular relative to the travel plane of the rake, and at least one dual-articulation connection device allowing relative rotation of the rake modules which the dual-articulation connection device connects about two axes substantially perpendicular relative to the travel plane of the rake, the two axes being spaced-apart in a longitudinal manner by an axial spacing, the rake defining at least two sub-assemblies of rake modules, the rake modules of a same sub-assembly being mutually connected by the single-articulation connection devices, each sub-assembly being connected to the or each adjacent sub-assembly by the dual-articulation connection device, the axial spacing being less than a distance between body ends of the two subassemblies connected by the dual articulation connection device, at least one of the sub-assemblies of rake modules comprising two carrier modules and a carried module without a supporting and guiding assembly and suspended between the carrier modules, a passage between each pair of adjacent carrier modules connected by the dual-articulation connection device, the passage allowing passengers to move between the carrier modules.
