A rail vehicle, especially a passenger train car for high-speed trains provided with air springs associated with each swivel truck in symmetry with the longitudinal central plane, their distance from center to center being so much smaller than the track gauge of the wheels that, if one air spring bellows fails, the weight of the car body will be distributed to the wheels in such a manner that the unloading of the wheels on the one side will not be such as to create the danger of derailment. To stabilize the car body the latter is joined to the swivel truck frame by a resilient linkage which permits vertical movements of the car body but opposes any lateral tilt of the car body by means of a resilient force. The resilient linkage is able to cause the car body to tilt towards the inside of curves when the car is negotiating curves. The swivel truck can be designed either as a driving or as a non-driving truck.
A rail vehicle with swivel trucks comprising at least two air springs connected directly with one another through a clear passage and disposed symmetrically with the longitudinal central plane of said rail vehicle between a car body and each swivel truck, the distance between the centers of said air springs being smaller than the track gauge of the wheels, said air springs having connected thereto means for instantaneous discharge of air should one of said air springs fail, said car body being connected to said swivel truck by a stabilizing resilient linkage comprising a torsion bar disposed across said car body, said torsion bar connected rigidly at each end to a horizontal lever which extends lengthwise of said truck, each of said horizontal levers flexibly connected to a connecting rod which runs generally vertical and is connected at its opposite end from said horizontal lever to an intermediate support on the swivel truck frame or to the swivel truck frame itself.
