In a rail vehicle having a car body (5) and having a bogie (1) which has a bogie frame (2) for holding wheels or wheel sets and a carrier (3), which is connected to the bogie frame, for supporting a car body, a braking means, for example a friction surface (6), which is fastened between the carrier and the car body acts, in order to provide running stabilization, so as to dissipate a rotary movement between the car body and bogie by opposing said rotary movement with a counterforce. A preload means (7), for example a hydraulic plunger, imparts an adjustable preload or pressure force to the braking means (6), wherein the preload can preferably be controlled during driving operation of the rail vehicle by means of a controller (8).

Véhicule ferroviaire comportant une caisse (5) et un bogie (1), qui comprend un châssis de bogie (2) destiné à recevoir des roues ou des essieux montés, et une poutre (3) reliée au châssis de bogie pour supporter une caisse. Un moyen de freinage fixé entre la poutre et la caisse, par exemple une garniture de friction (6), produit une force antagoniste qui s'oppose, par dissipation d'énergie, à un mouvement de rotation entre la caisse et le bogie afin de stabiliser la marche. Un moyen de précontrainte (7), par exemple un tampon hydraulique, imprime au moyen de freinage (6) une précontrainte ou une force d'application réglable, la précontrainte pouvant de préférence être commandée au moyen d'une commande (8) pendant le déplacement du véhicule ferroviaire.
