Abstract: A railroad freight car includes a loading platform and two wheelsets, two double-axle running gears or two bogies, and cushioning is effected by leaf suspension springs suspended by links from spring brackets. The object of the invention is to provide a railroad freight car by using simple, economic devices, in which a facility is provided for driving the railroad freight car beneath cargoes, especially swap bodies or interchangeable containers, for raising the loading platform and, following the reception of the cargo, for lowering the loading platform back into a travel position so as to enable the railroad freight car to be loaded and unloaded independently from loading appliances extraneous to the car. This object is achieved by providing a lifting element interposed between each suspension ring and an associated spring bracket of the loading platform or of the bogie frame.

Abstract: A running gear unit for low-floor rail vehicles includes a running gear frame on which individual wheels are rotatably mounted through a respective rocker and the rocker is articulatingly attached and supported by primary springs. The running gear frame is connected to a car body of the low-floor rail vehicle through two articulated rods having one end being articulatingly mounted at a distance from one another on a crossmember of the running gear frame and another end being likewise articulatingly attached to the car body. The car body is supported on the running gear frame through secondary springs being mounted in pockets near transverse ends of the crossmember. Transverse stops are disposed at a distance from one another in the crossmember for limiting transverse movement of the car body relative to the running gear unit.

Abstract: The present invention pertains to the connection of two multi-axle running gears into a running gear group for rail vehicles with low-lying platform, wherein the running gears have at least two wheel sets with small wheel base and a running gear frame consisting of side walls and crossbeams betweenn two axles. The wheel sets are mounted in the running gear frame via axle bearings, and each running gear is connected to the platform with false pivot only via a leaf spring and link suspension located transversely in front of and along each side wall. To ensure that the correct turn-out angle of each running gear and each running gear group is freely guaranteed during cornering, and at a correct axle load equalization of the running gears of each running gear group is ensured.

Abstract: A bogie for rail vehicles with a low-seated loading ramp, comprises at least two sets of wheels with a small axle base and a bogie frame comprising lateral cheeks and a traverse extending between every two axles. The sets of wheels are clamped into the bogie frame by axle bearings, and the bogie is connected to the vehicle frame merely by a carrying leaf spring carried by suspension rings. A fixing device cooperates with the suspension rungs to limit the movement of the bogie relative to the rail vehicle. The rocking or swaying properties of the bogie are optimized to improve the running behavior on straight stretches as well as on curves while providing the required transverse play of the bogie. The construction is made more favorably by employing long suspension rings.

Abstract: The invention relates to a slider (1) for track vehicles which allows for horizontal relative movements in the longitudinal as well as in the latitudinal direction between the superstructure, such as a freight car body or another vehicle body, and the running gear or between running gear parts. The invention has the task of retaining the effect of the friction in a slider of the described kind in one horizontal direction while eliminating it in the other direction. This problem is solved by mounting the slider on coupling elements, which allow for a nearly unrestricted sliding of the slider within a certain range in one of the two horizontal directions (longitudinally or latitudinally) and which fix the slider rigidly in the other one of the two horizontal directions.
