Railway Coupling Accessories TRIZ Cases

A force-triggered second lock keeps the rail coupler knuckle secure in normal use, yet releases during crashes to preserve alignment and energy absorption.

A detachable actuator and fixed receptacle enable safer rail vehicle uncoupling by blocking unauthorized actuation and lowering operating force.

A bearing-shaft control linkage coordinates the lock and air valve so rail vehicles avoid unintended uncoupling and brake-triggering faults.

A one-piece cast support with an internal guide block and spring assembly simplifies railway coupling head centering while cutting weight and fabrication cost.

Spring-loaded return levers center a train coupling arm with less weight, lower manual effort, and easier retrofitting in tight spaces.

Fixed hook and positioning structures let a transition coupler self-align with BSI couplers for stable automatic coupling and easier rail rescue.

Sensor-verified hooking groups and screw actuators enable automatic coupling and release of moving freight wagons with high towing resistance.

A pivoting, detachable coupling rod support preserves the deformation path of rail coupling energy absorbers during crashes.

A control cam and preload torque mechanism keep rail coupler uncoupling force more constant, reducing peak loads and automated system stress.

An automatic rotator uncouples rail vehicle couplers with low manual force, reducing protruding hardware risks and speeding separation.
