Tractor-Trailer Combinations TRIZ Cases

A pivotable hitch plate with a remotely controlled stabilizer assembly manages trailer alignment.

A fifth wheel mounting area transmits forces between trailer and tractor vehicle chassis while strengthening the frame via a detachable U-profile member.

A retractable fifth wheel cover uses a magnetic anchor bar for secure attachment to the truck frame.

Polymer skid plate cover engages recesses with projections to reduce friction and wear between fifth wheel coupling and hitch assembly.

Vertical kingpin entry via a funnel receiver simplifies alignment in confined spaces while a latching mechanism confirms secure locking.

A fifth wheel glider hitch uses slide rails and a spring-loaded locking pin to secure the assembly in precise positions along the track.

An axle height control system adjusts drive axle load to improve traction during off-road starting maneuvers.

A compact yaw angle measuring device distributes sensor elements across separable coupling partners to minimize spatial requirements.

A hydroformed skid plate uses circumferential ribs and a central embossment to enhance structural stiffness.

Motor-driven blockers engage trailer corners at 15-degree angles to prevent jackknifing while serving as stairs when parked.

A removable capture plate prevents rotation between a fifth wheel trailer pin box and hitch assembly.

Rotating the dolly axle frame relative to the tow bar achieves steering capability while eliminating complex mechanical transmission components.

A gooseneck coupler assembly uses a pivot retention mechanism to constrain rotational movement relative to the hitch ball.

A monolithic gooseneck hitch assembly integrates beams and rails into a single weld-free structure for secure load attachment.

A hitch assembly with a vertically adjustable mount and pivotally coupled foot features multiple attachment points.
