Train Hauling Devices TRIZ Cases
- Road-Rail Excavator Bogie With Pendulum Rail Axle Compensation
A pendulum-mounted rail axle helps a road-rail excavator maintain rail contact on uneven track, improving guidance and reducing derailment risk.
- Road-Rail Excavator Bearing Assembly for Pendulum Rail Axle Stability
A switchable bearing lets pendulum-mounted rail axles absorb rail unevenness, maintain rail contact, and lock for higher load capacity.
- Magnetic Traction Assembly for Railcar Mover Downforce Control
Electromagnets lowered near the rails add downforce only when needed, boosting railcar mover traction without extra ballast or larger power sources.
- Road-Rail Freight Vehicle Wheel Switching for Faster Low-Cost Transport
Separate road and rail wheel sets let one freight vehicle switch modes, cutting labor and fuel costs while avoiding rail yard delays.
- Rail Car Brake Coordination for Wave Energy Control
Selective braking across distributed rail cars cuts wave energy during indexing and dumping, reducing coupler fatigue on graded tracks.
- Movable Route Guide Switching for High-Speed Carrier Transfer
Movable route guides switch carrier vehicles between linear motor paths, preserving precise guidance while enabling faster, flexible material flow.
- Railcar Mover Magnetic Downforce Assembly for Ballast-Free Traction
On-demand magnetic attraction to the rails adds downforce for railcar movers, improving traction without ballast or a larger power source.
- Automated Gladhand Claw Coupling for Railcar Air Hose Braking
Motorized claws grasp and position a railcar air hose automatically, removing manual coupling risk while maintaining brake control.
- Rail-Guided Wagon With Spring-Biased Wheels for Wear Control
Spring-biased wheel subsets keep a form-and-seal machine wagon engaged with its rail, reducing manual adjustment, downtime, and wear.
