Railway Wheel Guards/Bumpers TRIZ Cases
- Wheelset Axle Ballistic Shell With Integrated Fastening
An integrated shell and fastening strap protects rail wheelset axles with secure closure, low installation space, and better impact and corrosion resistance.
- Rail Wheel Traction Airflow Control With Selective Orifice Switching
Selective compressed-air flow through different nozzle orifices cleans wet or contaminated rail surfaces to maintain traction under pressure loss.
- Rolling Axle Protector Sleeve for High-Speed Impact Damping
A grooved sleeve with compressed damping and movable fixing absorbs impacts while preserving axle rotation and dynamic behavior at high speed.
