Date Dec. 23, 1982.Device for ensuring the vertical suspension of the chassis of a bogie and the longitudinal and transverse coupling of each box of the chassis in a driving or carrying railway bogie, comprising a vertical suspension spring through which the bogie frame is supported on the axle box, thereby creating a rotary torque on this box, and including two flexible couplings mounted spaced in altitude between the frame and the axle box so as to be compressed when the axle box tends to rotate under the effect of the rotary torque. The rotary torque is provided by two suspension springs of helicoidal spring type which are mounted on each side of the vertical plane passing through the axis of the axle, and by the fact that each vertical coupling is constituted by at least one elastic stud forming a monoblock whose terminal cross-sections are fixed to a support surface of the bogie frame and to a support surface of the axle box, so that the compressive force due to the suspension springs results in low shear strength in the vertical direction.
