Lateral pressure which develops in the front wheelset when traveling along a curved track is decreased while suppressing an increase in costs as much as possible. A two-axle truck for a railway car has a front wheelset having wheels with a first tread gradient and a rear wheelset having wheels with a second tread gradient which is different from the first tread gradient. The tread gradient of the wheels of the rear wheelset is larger than the tread gradient of the wheels of the front wheelset.

L'invention porte sur un boggie à deux essieux pour un véhicule ferroviaire, structuré de telle sorte qu'une force apparaissant sur un essieu avant lorsque le véhicule circule sur une voie en courbe est réduite, ce que l'on obtient avec une augmentation de coût réduite autant que possible. Le boggie à deux essieux possède l'essieu avant comportant des roues ayant une première inclinaison d'écartement de bande de roulement et possède également un essieu arrière comportant des roues arrière ayant une seconde inclinaison de bande de roulement différente de la première inclinaison de bande de roulement. L'inclinaison de bande de roulement des roues de l'essieu arrière est supérieure à l'inclinaison de bande de roulement des roues de l'essieu avant.
