ABSTRACT:
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.
