Abstract (en)
[origin: EP0177459A2] A bogie for wagons of high-speed freight trains includes a frame (10) formed by two side members (12) interconnected centrally by means (14) for allowing relative angular movements only in substantially vertical planes, and a load-bearing beam (28) supported by the frame with the interposition of two lateral groups of vertical-axis helical suspension springs (26) which operate progressively in dependence on the load bearing on the bogie. Between the frame and the load-bearing beam are also interposed resilient lateral buffer means (50, 52, 58) which operate progressively, and friction damping means (64, 66) for the vertical and transverse movements.
