DEVICE FOR REDUCING SIDE ACTION OF RAILWAY VEHICLE WHEELSETS ONTO RAIL TRACK Russian patent published in 2001 - IPC

FIELD: railway transport. SUBSTANCE: invention relates to devices adjusting position of wheelsets of three-axle bogies when negotiating curved sections of track. Device has at least one controllable resilient pneumatic apparatus installed at each wheelset of three-axle bogie. Each pneumatic apparatus is connected through its housing or rod with bogie frame and, respectively, by rod or housing, with frame of traction motor. Pneumatic spool is arranged parallel to middle wheelset. Body of spool is coupled with bogie frame, and its rod, with traction motor frame of middle wheelset. Holes of spool are coaxial with pipelines communicating with rod and rodless spaces of controllable pneumatic apparatuses. Device is furnished also with two- mode compressed air pressure regulator connected by its rod with traction electric motor frame or housing of traction reduction gear of middle wheelset. Invention provides controllable radial setting of extreme wheelsets of three-axle bogie and increased performance characteristics of vehicle. EFFECT: reduced wear of wheel flanges and rail side edges, increased wheel-to-rail adhesion coefficient, reduced noise. 3 cl, 3 dwg
