Railway Couplings TRIZ Cases
- Railcar Coupler Lug Wear Restoration via Weldment
Gauging pulling lug wear enables precise weldment application that restores original dimensions, preventing uneven loading and extending service life.
- Railroad Knuckle Pin with Stress Relief Slots
Segmented tubular knuckle pin absorbs bending forces via elastic deformation, preventing failure in railroad coupler assemblies.
- Flexible Clamp Recess Eliminates Screw Fatigue
A flexible clamp body with a recess deforms elastically to ensure a flush fit against the base yoke.
- Rail Vehicle Anti-roll Device Coupling for Torsional Load Reduction
A coupling device links anti-roll devices to enable counterforce-free displacement along the rail vehicle longitudinal axis.
- Rail Coupling Drawbar Pivoting Mechanism for Mixed Towing
A rail coupling drawbar pivots its head into a horizontal plane to enable automatic connection, reducing manual setup times for mixed towing operations.
- Train Measuring Appliance External Mounting
External measuring appliance mounts to train automatic coupling via quick hooking mechanism.
- Railcar Yoke Weight Reduction via Austempered Ductile Iron
Austempered ductile iron yokes reduce mass while maintaining strength, resolving weight-strength trade-offs in railcar couplers.
- Railway Vehicle Coupling Device with Vertical Support Member
A railway coupling device uses a dedicated support member to transmit vertical loads between connected vehicles.
- Emergency Catch Device for Rail Sedan Cars
An emergency arresting device prevents a chassis-less rail sedan from tipping when anti-roll support fails.
- Train Coupler Adapter With Swiveling Safety Bracket
A train coupler adapter uses a swiveling safety bracket to create space for draw hook insertion.
- Railway Coupler Anti-Creep Mechanism with Bossed Rotation Shaft
A coupler anti-creep mechanism uses a bossed rotation shaft to hinge the lockpin rod and shank while preventing unintended unlocking.
