Rail And Road Vehicles TRIZ Cases

Offset bogie and inter-body joint axes let semi-trailer trainsets handle tight curves with simpler articulation and lower manufacturing cost.

Passive junctions and transition spans let hybrid vehicles switch between road and rail automatically, improving steering, traction, and safety.

Temperature-controlled steel sleeves create interference-fit joints on lightweight frame bars, cutting railgear weight while limiting wear.

Controlled damping between the rail wheel carrier and chassis stabilizes excavator travel on uneven tracks and helps prevent derailment.

Independent pendulum rail axles keep constant rail contact on twisted track, reducing flange wear and derailment risk.

A guided support-foot linkage keeps the same lateral support width in two rail driving positions, improving stability while avoiding rail collisions.

A switchable friction wheel pressed onto the rail boosts traction and braking while reducing road wheel wear during rail operation.

Horizontal loading couples road trailers to spaced bogies without vertical lifting, cutting energy use, coupling time, and load peaks.

An offset bogie and inter-body pivot layout helps articulated semi-trailer trains pass tight curves while simplifying body ends and motorization.

A socket-mounted removable hitch frame lets one well car carry trailers or containers while avoiding permanent weight and load-capacity loss.

Independent wheel arms and actuators keep rail wheels aligned on uneven track, improving road-rail vehicle stability and derailment resistance.

Offset lateral and vertical guides let track wheels retract for road width and deploy for rail gauge without dedicated infrastructure.

Removable hitch and deck modules let a well car carry trailers or containers while preserving load capacity and avoiding permanent structural changes.

A foldable vertical linkage deploys hi-rail wheels without bulky rotation and uses a spring-actuated pin to lock positions automatically.

Integrated rail-to-ground transfer units let this track processing machine move on rails and terrain, cutting manual transport and setup time.

An integrated rail-ground displacement unit lets a track processing machine move manually on rails and ground without auxiliary transport.

A suspended support frame keeps stabilizer wheels in firm rail contact during chassis tilt, increasing wheel load and reducing derailment risk.

Retractable rail wheels let truck trailers switch onto railroad tracks, cutting load transfer time and enabling multi-trailer locomotive hauling.

Electric actuators and interference-fit sleeves cut hi-rail frame weight and hydraulic complexity while preserving axle movement control.

Interchangeable manual, air, and cable pin-off locking makes rear railgear easier to fit across vehicle sizes while keeping deployment and stowage secure.

Retractable wheels enable door-to-door service on roads while rail mounts ensure safety, resolving the contradiction between flexibility and reliability.

Idler wheels engage rails via lifting members to reduce pressure on movement means, improving traction and safety in tunnels.

Interchangeable road and rail axles allow the chassis to switch modes, eliminating crane requirements for track placement.
