Abstract: Wheels for goods wagons with small and large diameters, in addition to wheel sets equipped with wheels of this type for running gear, which are dependent on a highly passive radial positioning when negotiating curves and must remain stable at high speed. The inventive wheel profile is characterized as a result of the relatively large entry radius into the transition area from the running surface to the wheel flange by a low equivalent conicity. This enables a quieter running of the wheel set when the latter is travelling in a straight line. In curves, there is a sufficient rolling circle differential, permitting less wear and tear.

Abstract: A device for connecting rail vehicles formed of a plurality of interconnected first and second car parts having a rotary joint with a swiveling crown, includes a rotary-restraint device provided in the joint region between each two car parts. The rotary-restraint device includes two sliding bodies disposed at the periphery of the swiveling crown of the rotary joint. The sliding bodies interact with one another in a frictionally engaged manner and are each fastened to one of the two car parts connected in the rotary joint.

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: A bogie or truck for high-speed rail vehicles or railway cars includes an H-shaped bogie or truck frame, primary springs cushioning the bogie frame, and a lateral bolster being movable relative to the bogie frame, receiving a coach or car body and being cushioned relative to the bogie or truck frame by air springs. The object is to provide a bogie with a low number of contact points with the coach body, which allows a configuration for rotational retardation, which has a minimum structural width and low weight, which permits small air spring bellows, which allows the installation of additional air reservoirs for the air springs below the lateral bolster and which has additional assemblies disposed at locations which keep the bearing components free from bending or torsional stresses. According to the invention, each air spring is supported directly on the side wall of the bogie frame.

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: The present invention pertains to a bogie for high-speed railborne vehicles, in which the wheel sets are guided on the bogie frame by double leaf spring wheel forks. Stable, quiet straight travel of the bogie over straight sections at top speeds and radial adjustment of the wheel sets in rail bends at low tracking forces is achieved by arranging a a roll stabilizer damping the horizontal longitudinal movements between the axle bearing and the bogie frame between the leaf spring wheel forks of each double leaf spring wheel fork.

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.
