Rail-Engaging Wheels TRIZ Cases
- Railway Wheel Elastic Damping Elements for Wear Reduction
Segmented elastic elements with symmetrical faces distribute loads to reduce wear on railway wheels while maintaining reliable vibration damping.
- Solid Rail Wheel Cavity Design for Low Sound Emission
A solid rail wheel uses arched walls and openings to form a cavity that reduces weight while maintaining stiffness.
- Rail Vehicle Wheel Sound Absorber with Offset Slotted Plates
Parallel absorber plates feature offset slits covered by adjacent slot-free sections to create a layered damping structure.
- Aerodynamic Noise Reduction Member for Railroad Brake Disks
Segmented protruding portions occlude between fins to reduce aerodynamic noise while preventing plate warpage from uneven rigidity.
- Rail Wheel Friction Disc Coating for Wear Reduction
Phosphate and lubricant layers on rail wheel contact surfaces prevent adhesive wear and seizure during braking operations.
