摘要:
The invention relates to a system for securing and/or controlling the final position of a tongue rail (14) that can be adjusted in relation to a rigid rail (12). A catch element extends from said tongue rail and interacts with a lever element in such a manner that in the respective final position of the tongue rail the latter is supported and the position of the tongue rail is measured.

The invention relates to a superstructure points device, in particular intended for a grooved rail, comprising a box-like substructure (32) with stock rail (14), if necessary an additional/supporting rail (16) and slide plate (18) on which a tongue rail (20) is slidably mounted. In order to mount the rails of the points device elastically, while also allowing the option of simple removal from the rail/road bed, it is proposed that the box-like substructure (32) is mounted elastically in a stationarily arranged frame (38) of the points device.

A rail fixing device including a tensioning clamp extending from a holding element and removably arranged on a ribbed plate on which the rail base is mounted. The ribbed plate is placed on an elastic intermediate layer which is maintained in a required prestressed state by the holding element.

Fastening for a rail and arrangement for fastening of rails The invention relates to a fastening for a rail for securing a rail (10) whose foot is resting on a concrete sleeper (16), comprising at least one elastic clip (20) having several legs of which at least one leg extends inside a shoulder (42, 44) or channel of a holder (24) that is connected to the concrete sleeper, and at least one further leg rests on the rail foot. For securing a rail to the necessary extent with simple design means and in space-saving form, it is suggested that the holder (24, 26) is arranged detachably in the concrete sleeper (16) or in a plate element resting thereon and is connected to the concrete sleeper by a bolt element.
摘要:
A superstructure arrangement for a track comprising a rail fastened to a securing device such as a ribbed plate which is disposed above a concrete sleeper, with an intermediate layer extending between the sleeper and the securing device. The rigidity of the intermediate layer is variable and rated so that at the maximum permissible stress in the rail, caused by bending under wheel lead, the elastic property changes to substantially non-elastic.

A bearing for a section of a track includes, along the track sections, profile sections which deviate from each other, especially in the form of points. A plurality of supporting points is provided with a ribbed plate, in addition to an intermediate layer made of an elasticized material disposed between the ribbed plate and an associated railway sleeper. In order to obtain identical subsidences along the sections of track, substantially each support point has an identical maximum subsidence with respect to each excavated track section.
摘要:
A method and device for the elastic bending of a support (16) with at least one bendable end (24), intended in particular for a flexible switch (10). To achieve an elastic line of a finite radius of curvature also at the free end of the support, a bending moment diverging from zero is generated in the elastically bendable end (24) of the support (14) by applying a force coupling to an auxiliary lever (28).
摘要:
A bearing system for a part of a railroad track, such as a rail-fastening or ribbed slab (10), supported by elastic elements on, for example, a railroad sleeper. The elastic elements form a spring system with a kinked characteristic curve such that when the spring system is subjected to force that is smaller than the forces active in the operative range (16) of the spring system, the characteristic curve rises steeply and, in the operative range (16), runs flat.
