Axle-Box Lubrication TRIZ Cases
- Low Floor Suspension Vehicle Multi-Joint Design
Multi-articulated vehicle design with horizontal intermediate level and controlled ramps for barrier-free access.
- Roof Joint Dampers With Common Axis For Articulated Vehicle Guidance
A roof joint uses dampers rotating on a shared axis to guide complex relative movements while minimizing force transmission to supply lines.
- Articulated Bogie with Air Suspension for Intermodal Rail
Articulated bogies with air suspension reduce lateral forces and wheel wear on intermodal rail vehicles.
- Rail Vehicle Front Hatch Lifting Spindle Actuation
Modular lifting spindle drives pivot rail vehicle front hatches, reducing kinematic complexity and maintenance under harsh conditions.
- Rail Vehicle Adjustable Floor for Platform Height Adaptation
Segmented floor elevation mechanisms adapt rail vehicle boarding levels to different platforms, resolving accessibility trade-offs for wheelchair users.
- Force Sensitive Coupler for Model Trains
Integrating a force sensitive resistor into the coupler measures inter-car forces, enabling realistic motor and sound effects.
