Underframes TRIZ Cases
- Metal Profile Arrangement Enabling Friction Stir Welding
Parallel webs and flat support areas create a force path for friction stir welding, reducing distortion and post-weld processing.
- Rail Vehicle Levelling Piston End-Stop Guide Structure
Integrated guiding elements inside the levelling piston create end stops that save space and simplify rail vehicle assembly and maintenance.
- Rail Vehicle Levelling Piston Guide for Controlled End-Stop Motion
An integrated piston guide in a grooved levelling cylinder constrains rail vehicle motion, saves space, and resists shear forces.
