ABSTRACT Company called: USINES ET ACIERIES DE SAMBRE ET MEUSE "Railway bogie with frame having selective deformability" (Invention of Jean LIENARD) The sole-bars (1) bear on the axles by means of elastic suspensions (12) with frictional damping. The bolster (18) bears by means of elastic blocks (32) on the lower side of a window (24) made through each sole-bar. Each elastic block (32) bears on a face (31) of the sole-bar which has, in relation to the longitudinal direction (L) of the bolster (18), an inclination (A) such that the compressive force (F) of the elastic block has a horizontal component (FHT) which pushes the sole- bar so as to bear by its reference face (26) against a conjugate reference face (28) belonging to the bolster. Thus, the sole-bars (1) are constantly returned into a favoured configuration of perpendicularity in relation to the bolster. Use for effectively combatting parasitic deformations and sideways movements of the deformable- frame bogies. See Figure 3.
