RAIL VEHICLE BOGIE (VERSIONS) Russian patent published in 2005 - IPC

FIELD: railway transport.

SUBSTANCE: invention relates to design of devices for radial mounting of axles of bogie wheelsets. Proposed bogie contains frame, wheelsets with axle boxes, springs of axle box spring suspension, carriers connecting wheelset axle boxes with frame so that axle boxes of each wheelset are connected through brackets by two coaxial carriers or one carrier arranged parallel to longitudinal axis of bogie. In extreme wheelsets they arranged lower or upper than level of axle of corresponding wheelset. In first case, axle boxes of front wheelset are hinge-connected by second brackets with bellcranks hinge-connected by middle part by means of longitudinal ties with frame, second ends of bellcranks being hinge-connected with body by longitudinal ties. Axle boxes of rear wheelset are hinge-connected by second brackets by longitudinal ties with body. In second case, axle boxes of front wheelset are hinge-connected by second brackets with body by longitudinal ties, and axle boxes of rear wheelset are hinge-connected by second brackets with bellcranks with bellcranks, are hinge-connected by middle part with frame by means of longitudinal ties, and second end of bellcranks are hinge-connected with body by longitudinal ties. Longitudinal ties connecting brackets of axle boxes or connecting bellcranks with body are made energy absorbing.

EFFECT: automatic setting of bogie wheelsets when negotiating curved sections of tracks, stable running of wheelsets at speed up to 120 km/h.
