A system for articulated bogie-type rail vehicles in which the adjacent ends of the car bodies are pivotally and rotatably supported by supporting arms extending beyond their end trusses on a single-part connecting portal jointed by bellows to the car box ends and mounted on a transverse support. The portal is tightly enclosed by a sealing member on its full perimeter and has a spring mounted platform supported with vertical freedom of movement but with minimum play in all other directions on the bogie. This platform is pivotally arranged by at least one centrally located rotation ball race and by the supporting arms. This rotation ball race has three race rings and two rows of balls. Of these three race rings one race ring is kinematically associated with the front car body while another race ring is kinematically associated with the rear car body, and the third race ring is kinematically associated with the transverse support supporting the portal and the platform. |
