The track fastening system is first used to fasten the rails to a fixed base (eg concrete sleeper or concrete slab). Here, the track to be fastened is directly on the fixed base via the elastic intermediate layer. The lateral guide portion of the track receives the angle guides, which are formed in pairs between the precisely defined track passages. The angle guide directs the force introduced via the rails into the base of the load track. For this purpose, a shoulder (concrete shoulder) is constructed at a corresponding base for each angle guide, Rail Fastening System and an associated angle guide can be supported at the shoulder.
The function of the track fastening system is to clamp the track together with the rail bearing surface of the sleeper with a limited force. The tension is proportional to the sliding resistance and torsional impedance of the track fastening system. Both of the impedances are determinative for the positional stability of the mobile orbit joint. In addition, the tension forces resist the tilting of the rails in the presence of the guided force from the vehicle and thus ensure the required track geometry and safe vehicle travel.
Very high tension or preload is just indispensable in areas with large lateral guidance and large temperature fluctuations. Because of the purpose of load distribution, Rail Fastening System the modern rail fastening system is resiliently supported by the rails, which must have a vertical, high vertical vibration in addition to the high tension Fatigue strength.
The clamping force known in the prior art can achieve a tensile strength of 10 - 14 kN and a fatigue strength in the case of vibration up to 2.0 mm (vibration amplitude) based on the corresponding mounting condition. Except for some of the clamping clips used in the "fixed lane", Rail Fastening System the clamping clamp ensures fatigue strength in the case of vibration up to 3.5 mm with a tension of only IOkN.
A track fastening system fastened to the sleeves of the rail equipment (Gleisanlage), comprising at least one angle guide and at least one clamping clip which can be secured to the sleeper by means of at least one bolt, wherein the track (Schienenfufl) There is provided a track intermediate layer made of a rubber material to ensure electrical insulation of the track with respect to the track sleeper and / or the steel member of the rail fastening system.
A sleeper track fastening system for resiliently fastening a rail (2) force cooperatively to a track device, comprising at least one angle guide (5) secured to the sleeper (1) by means of at least one bolt (4) And at least one clamping clip (3), characterized in that the bending radius of the clamping gripping arm (3a, 3b) of the clamping clip (3) is preferably in the range of 18-70 mm, wherein, Rail Fastening System in each clamping The ratio of the maximum bending radius of the clamping gripping arm to the minimum bending radius is less than or equal to or less than the minimum bending radius of the gripping arm, and the ratio of the weight to the width of the angle guide plate is 1.3 g / mm, Preferably about 1.25 g / mm.
