When lower bolster forms the trend skidded off to bend outside, it is in contact to be formed to rail with rail foot inner side edge by retention bead
The barrier effect of lower bolster, so that playing prevents railway rail pad from generating displacement to skidding off on the outside of bend, to guarantee train
Even running.Meanwhile the area of the cross section of retention bead is gradually increased from top to bottom, this is actually to make retention bead shape
At big top and small bottom shape, such shape can improve the bonding strength between retention bead and plate body well,
This still is able to collide in the inner side edge with rail foot using rear retention bead for a long time also for guarantee railway rail pad
When play the role of anti-positional shift to railway rail pad.
3, the quantity of retention bead is two, is fixed by increasing fixed point composition both ends, ensure that the steady of railway rail pad
It is qualitative.
4, energy-absorbing main body includes several energy-absorbing protrusions, is evenly distributed on the pressure energy of train in each energy-absorbing protrusion,
Energy-absorbing main body is avoided the case where excessive local pressure, fatiguability damage occur.Meanwhile plate body surface is not provided with the ground of energy-absorbing protrusion
Side each self-forming energy-absorbing gap buffer function, while the setting in energy-absorbing gap are played, so that respectively by each energy-absorbing gap
A energy-absorbing protrusion is gradually connected to form an entirety, when receiving the pressure of train, can achieve the effect that whole stress, make adjacent
Energy-absorbing protrusion it is not easy to fatigue, or even fracture, and then allow entire energy-absorbing main body have preferable fatigue performance.
5, the shape of each energy-absorbing protrusion is in positive eight terrace with edges structure, and upper bottom surface and bottom surface are octagon, is had
The advantages of stable structure, and ensure that the forced area under train pressure, avoid energy-absorbing protrusion forced area is too small from locating at any time
In deformation fatigue state.Meanwhile the setting of terrace with edge structure, so that the area of energy-absorbing protrusion upper bottom surface can be less than the face of bottom surface
Product, this is allowed under the pressure effect of train, and the pressure that more downward compression energy-absorbing protrusion needs is bigger, is passed through to traveling
Train plays a preferable buffering effect, ensure that the stationarity of train driving.
6, the utility model is additionally provided with two securing plates, and the height of each securing plate is below the height of each energy-absorbing protrusion,
The setting of securing plate is not in the case where influencing energy-absorbing protrusion and train stress, so that the structure of this railway rail pad is more stable,
Increase the endurance of this railway rail pad.
7, the position positioned at each energy-absorbing protrusion and each energy-absorbing protrusion for being located at plate body lower surface of plate body upper surface is staggered,
This guarantees the energy-absorbing gaps that the energy-absorbing gap of plate body upper surface will not correspond to lower surface, so that the thick bottom of plate body will not be too
Thin, so that the intensity of this railway rail pad is stronger, fatigue performance is preferable, structure is relatively stable.
