Bogies TRIZ Cases
- Hydraulic Torsion Bar Control for Rail Vehicle Anti-Roll Torque
Hydraulic connecting rods let a rail vehicle torsion bar switch between bidirectional and unidirectional anti-roll torque for different track curvatures.
- Adjustable Hydraulic Torsion Bar for One-Way Anti-Roll Control
Check-valve hydraulic rods switch between fixed and one-way follow-up length states to match rail curves with bidirectional or unidirectional anti-roll torque.
- Hydraulic Axle Link Bearings With Damping for Rail Vehicle Stability
Connected fluid chambers and a damping element tune axle link stiffness to stabilize wheelsets, cut wear, and improve rail running.
