A running gear for a rail vehicle has sprung longitudinal members 2 of plastic, connected to one another by means of a cross-member structure 5 and at their free ends to axle-boxes 4 for rail wheels. In order to obtain optimal stability of the wheelset guidance with reduced loading of the sprung longitudinal members, the longitudinal members 2 each have at least two flexural springs 2.1, 2.2, 2.11 2.22, between the ends of which in each case an axle-box 4 is fixed in symmetrical arrangement.

L'invention concerne un train de roulement pour un véhicule sur rails, qui comporte deux longerons (2) en matière plastique faisant ressort, qui sont reliés l'un à l'autre par une structure à traverse (5) et, par leurs extrémités libres, à des paliers de roue (4) pour roues roulant sur rails. Pour qu'il soit possible d'obtenir une stabilité optimale du guidage du jeu de roues tout en ayant une sollicitation réduite des longerons faisant ressort, lesdits longerons (2) sont chacun constitués d'au moins deux ressorts de flexion (2.1, 2.2, 2.11, 2.22), entre les extrémités desquels est fixé chaque fois un palier de roue (4) selon une disposition symétrique.
