A wave-shaped stopper with wear plate and method for preventing steel spring from breaking
A steel spring and wear plate technology, applied in railway car body parts, bogies, axle box installation, etc., can solve the problem of difficult to effectively reduce the metal fatigue of steel springs, without adjusting the stiffness, and greatly improve the resistance of steel springs to fracture, etc. problems, to achieve the effect of compact structure, ensuring comfort, and multiple vertical loads

Embodiment 1
[0039] Such as Figure 4 As shown, a positioning base 4 is fixed above the axle box 5, and a double-volume spiral steel spring 2 is arranged above the positioning base 4, and the steel spring 2 supports the weight of the locomotive above the bogie frame 6. In order to reduce the vertical load borne by the steel spring 2 and reduce the metal fatigue generated by the steel spring 2 during locomotive operation, thereby preventing the steel spring 2 from breaking, a vertical stop 1 is provided in the steel spring 2 . The base flange 132 of the vertical stop 1 abuts against the positioning base 4 , and since the vertical stop 1 and the positioning base 4 are both revolving bodies, the vertical stop 1 can be stuck in the positioning base 4 . A frame guide cylinder 3 is arranged directly above the vertical stop 1. When the locomotive is unloaded, the vertical stop 1 does not contact the frame guide cylinder 3; when the vertical load of the locomotive increases, the frame guide cylind...
