Railway Braking Systems TRIZ Cases
- Rail Vehicle Mark-Aligned Stopping With Closed-Loop Brake Control
Real-time wheel-pair deceleration feedback adjusts braking force to improve rail vehicle stopping accuracy at platform marks.
- Rail Vehicle Brake Release Control During Door Closing
Braking force is reduced during door closing and restored if roll-away is detected, enabling faster rail vehicle restart without unsafe movement.
- Rail Wheel Brake Friction Ring Body Using Segmented Metal Cutting
Segmenting the brake assembly into separate metal and friction components eliminates complex casting molds while maintaining thermal conduction.
- Electro-pneumatic Brake Multi-stage Pressure Control
A relay valve manages train pipe pressure via an equalizing reservoir to enable multi-stage braking force adjustment.
- Rail Vehicle Adhesion Control Coordination
A control device coordinates wheel-slide protection and sanding systems in rail vehicles.
- Adhesion Agent Dosing for Rail Braking
Two dosing devices apply adhesion agents based on measured friction values, preventing uneven distribution caused by wind and braking forces.
