How does the fastener system work
Working principle of fastener system
Basic working principle
The fastening system usually includes spring bar, fastening plate, bolt, nut, flat washer, underrail plate and other components. When a bolt is tightened, it compresses the spring or gusset, causing it to deform. The buckle pressure created by this deformation compacts the rail against the rail foundation, preventing it from moving.
Working principle of spring bar fastener
For the elastic fastener system, its working principle is more specific. When the bolt is tightened, the spring bar is compressed and deforms. The front two legs of the elastic bar act on the gauge stop, and the gauge stop holds down the rail. In this way, the rail is firmly fixed to the track. In the process of train running, when the rail is subjected to vibration and impact force, the elastic bar can absorb these energies and reduce the impact on the track foundation through its own deformation.
