Railway Vehicles TRIZ Cases
- Progressive Shear Spring Suspension for Adaptive Load Handling
A vehicle suspension uses tapered elastomeric shear springs to deliver a continuously increasing spring rate under compressive loads.
- Compressor System with Switching Device for Rail Vehicle Air Supply
A compressor system employs a switching device to isolate compression stages, reducing electrical power consumption while maintaining high delivery capacity.
- Magnetic Levitation Guideway Suspension for PRT Systems
Permanent magnet repulsion and electrodynamic stabilization replace wheel bearings in networked guideway transit systems.
- Railway Sensor Package for Wheel Detection and Speed Measurement
A rail web sensor package uses strain sensing to detect wheel passage and determine train direction.
