FIELD: railway transport. SUBSTANCE: suspension has rod with beads which is coupled with reduction gear bracket at one side and with cross bar of bogie frame through support plate and resilient members at other side. To increase service life of resilient members, surface of beads is made in form of plane of support ring with smooth change to line of intersection of curvilinear periphery surface of bead with surface of cone whose generating line is arranged at angle relative to support ring plane equal to maximum angle of deflection of rod from its vertical position. Vertex of cone lies in point of intersection of plane of support ring with axis of rod. EFFECT: increased service life of resilient members. 5 cl, 4 dwg
