Tractor-Trailer Combinations TRIZ Cases

Automated propulsion and remote control reduce operator physical strain while standardizing railcar attachment points.

A riser lift mechanism moves the platform vertically and horizontally to support vehicles.

A weight sensing assembly mounts to semi-trailer wheels and measures tire pressure changes to calculate axle loads.

Segmenting the driveline into independent engines eliminates steered axles, reducing swept path while increasing payload capacity.

Convertible coupling allows independent trailer operation, resolving the trade-off between towing capacity and device complexity.

A non-cabin articulated truck uses vertical pin articulation and hub motors to transport heavy loads in confined underground spaces.

A connecting member pivots vehicle parts on perpendicular axes while a universal joint links drive shafts to accommodate relative movement.

Gradient metal matrix composite wear plate combines silicon carbide durability with graphite lubrication to eliminate grease dependency in fifth wheel hitches.

A towing vehicle coupling housing with a concavely curved stop surface guides trailer rotation around a vertical axis.

A trailer safety strap detects obstacles in the tugger train gap to trigger an emergency signal.

Rear load bed slides atop front load bed to enable curtain-sided trailer operation.

A universal folding boom trailer supports towed vehicle weight on dual axles to elevate steering tires.

Replacing the fifth wheel arrangement with a direct drawbar coupling mechanism eliminates high torque induced skipping risk in port load handling operations.

Segmented support plates with filler inserts distribute loads across multiple weld joints, reducing stress concentration at rigid connections.

A kingpin assembly uses a collet sleeve and Belleville spring to constrain vertical movement within the receiver housing.

Adjustable fork guides and magnetic latches enable a forklift to tow multiple trailers, eliminating the need for a separate tugger vehicle.

A fifth wheel hitch lifting apparatus moves the heavy coupling between truck bed and overhead storage using a suspended carriage system.

Segmented locking components and preliminary action principles prevent false engagement during frequent terminal tractor operations.

Rearward-tilted stabilizing axes enable spring bars to counteract trailer sway by adjusting tension without adding separate control components.
