The invention relates to a bogie construction which comprises at least two stiff axles (1a-1c) which are interconnected by a rocking lever (10a, 10b). The rocking lever is pivoted in its middle so that it can move in its longitudinal direction as a result of steering movements. The rocking lever is preferably connected to the bogie axle that turns least by means of a joint of an ear (13), and thus this axle determines the longitudinal displacement of the rocking lever. The rocking lever is connected to the other axles which turn more by means of suspension rods (8a, 8b). According to a preferred embodiment of the invention, a suspension rod pivoted below the axle is used, and thus the suspension rod can be made as long as possible. Consequently, the suspension rod tilts less as a result of the longitudinal movement of the rocking lever.
L'invention concerne une structure de bogie comprenant au moins deux essieux rigides (1a-1c) qui sont reliés par un levier basculant (10a, 10b). Le levier basculant pivote en son centre de telle façon qu'il puisse se déplacer dans sa direction longitudinale suite à des mouvements de direction. Le levier basculant est, de préférence, relié à l'essieu de bogie qui tourne au moins à l'aide d'un joint d'une corne (13), et ainsi cet essieu détermine le déplacement longitudinal du levier basculant. Le levier basculant est relié aux autres essieux qui tournent plus à l'aide de barres de suspension (8a, 8b). Selon un mode de réalisation préféré de l'invention, on utilise une barre de suspension pivotant sous l'essieu et ainsi la barre de suspension s'incline moins en relation avec un mouvement longitudinal du levier basculant.
