Tractor-Trailer Combinations TRIZ Cases

A motor-driven linkage replaces manual 90-degree twisting in gladhand coupling, reducing seal wear and brake connection errors.

Negative torque from self-propelled trailers straightens articulated vehicle combinations, making reversing safer and easier to control.

Multiple puck and center-socket connections spread offset towing loads, reducing torsional stress and single-point failure risk.

Rear axle suspension adjustment keeps kingpin load below its threshold during loading, enabling higher semi-trailer payloads without extra axles.

Real-time coupling load control uses virtual wheelbase and axle force redistribution to raise payload and traction within legal load limits.

Magnetic flux sensing tracks fifth wheel jaw position to verify kingpin lock state, detect wear, and prevent towing disengagement.

A diagonal shock absorber and central suspension brace keep trailer-coupled vehicles aligned and stable on uneven terrain.

Ultrasonic sensors on the tow vehicle measure trailer angle without trailer-mounted recalibration, improving durability and redundancy.

A laterally sliding fifth wheel adjusts to steering angle so longer tractor-trailer combinations can meet turning circle limits and carry more payload.

An outrigger, alignment device, and gripper arm automate truck-trailer pneumatic and electrical connections with robust self-alignment.

A robotic arm lets an autonomous yard truck locate, connect, and test trailer hose couplings while navigating tight yard spaces.

Sensors and a drive assembly automatically verify hitch engagement and reposition the fifth-wheel for balanced autonomous vehicle operation.

A stress-absorbing coupling keeps modular trailer vehicles aligned while allowing pitch and limiting roll and yaw for stable high-speed off-road driving.

When sensor status is unclear, relative vehicle-trailer movement releases bracing and confirms a true locked coupling state.

Combining lock-mechanism signals with wave-based positioning helps verify a true locked trailer coupling and avoid false coupling outputs.

Pivotable plug-in units align coupling axes despite height and oblique trailer offsets, reducing contact wear and bending stress.

Multiple anchor and connection points let a base-and-latch hitch adapter secure varied truck-bed cargo quickly and reliably.

A pivoting lifting frame and stabilizing assembly let a shunt truck place a trailer stand remotely, reducing operator risk and trailer tipping.

Vertically adjustable cam and T-pin mounting reduces hitch rattle, improves operator feedback, and fits varied towing vehicle structures.

A telescopic rear sensor arm extends obstacle detection to the trailer end, improving reversing safety for driverless semi-trailer transport.
