Tractor-Trailer Combinations TRIZ Cases
- Trailer Suspension System with Rotary Tongle Lever for Ground-Level Loading
A trailer suspension system lowers the support surface to ground level using a pivoting rocker arm and rotary tongue mechanism.
- Gooseneck Trailer Dampening System Using Air Bladders
Air bladders decouple rigid connections to reduce vibration transfer while maintaining structural strength.
- Retractable Air Hose Retention Device for Tractor-Trailer
A retractable air hose retention device uses a spring-loaded cable to maintain elevated positioning.
- Sliding Towing Assembly with Pressure Distributing Plate
A sliding towing assembly guides a hitch pin away from the cab during turns while a pressure distributing plate mitigates stress on the vehicle bed.
- Gooseneck Towing Module With Pivoting Toe Extension
Pivoting toe extension lifts disabled haul truck frames to eliminate heavy counterweights and enable full 90-degree turns.
- Fifth-Wheel Kingpin Wear Detection via Color-Coded Elements
Color-coded wear indicators embedded in the kingpin structure enable reliable visual assessment of material loss, resolving manual inspection errors.
- Laser Scanner Cab-Trailer Angle Calculation for Autonomous Reversing
Computer system calculates cab-trailer angle from laser scanner coordinates, replacing visual estimation with precise autonomous reversing guidance.
- Steering Sensor Cam Disk Mechanism for Heavy-Duty Vehicle Angle Detection
Shaped cam disk replaces complex pivotable articulation to adjust steering angle relationship without hydraulic oil or collision stops.
- Automated Trailer Connection Robotic Arm Control
Sensors detect fifth wheel engagement for automated robotic arm connection, reducing manual labor risks and equipment wear during hook-up.
- Interchangeable Track Drive for Articulated Off-Highway Vehicles
Universal mounting structures allow interchangeable track units on articulated vehicles, reducing turf disturbance while maintaining ground clearance.
- Pivoting Coupling Cable Loop Management
Guided cable loops reduce size when pivoting, preventing damage in critical coupling areas.
- Sliding Drawbar Trailer Axial Guidance for Standard Vehicles
A trailer sliding drawbar maintains the median longitudinal axis within the towing vehicle vertical plane.
- Fifth Wheel Coupling Force Measurement via Intermediate Element
A fifth wheel coupling integrates force sensors into an intermediate element to transmit and detect load data directly from the trailer connection.
- Supportive Belly Pad for Rounded Trailer Structural Integrity
Segmented belly pad with parallel legs and transverse ribs enhances trailer structural integrity while reducing weight by 600 pounds.
- Sliding Hitch Self-Arming Latch Cam Mechanism
A sliding hitch uses a cam mechanism to pivot a latch pin into engagement with the carriage.
- Fifth Wheel Coupling Safety Lever Blocking Mechanism
A fifth wheel coupling uses a movable blocking element to constrain the pull handle in the closed position.
