Cross-Traction Transfer Frame for Multi-Trailer Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing system of using multiple tractors to tow trailers leads to increased equipment and labor costs, as well as transportation inefficiencies due to interference between tractors, which affects the overall efficiency of cargo transport.
Innovation Solution
A double-traction transfer vehicle design featuring a front traction mechanism, cross-arranged traction bars, a transfer frame, and a running device, allowing one tractor to efficiently pull multiple trailers by connecting them through retractors and saddles, enabling free rotation and separation of trailers during turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one tractor tows one trailer to facilitate steering, then steering control is improved, but equipment costs and labor costs increase
Solution Approach 1:
The patent combines multiple trailers into a single towing unit by connecting them through transfer frames and traction bars. One tractor can simultaneously tow multiple trailers that are linked together, merging what would otherwise require separate tractor-trailer units. This reduces the number of tractors and drivers needed while maintaining steering control through the interconnected structure.
Solution Approach 2:
The transfer frame serves multiple functions: it connects multiple trailers together, provides a structure for traction bars, enables rotation during turns, and allows for easy separation of trailers. This multi-functional design eliminates the need for separate steering mechanisms on each trailer while maintaining operational flexibility.
2Ease of operation
If one tractor tows one trailer, then steering during driving is facilitated, but transportation efficiency decreases
Solution Approach 1:
Multiple trailers are merged into a single operational unit that can be towed by one tractor. The trailers are connected through transfer frames and traction bars, allowing them to move together as one group. This increases transportation efficiency by reducing the number of tractors and drivers needed while maintaining the ability to steer during driving through the interconnected structure.
Solution Approach 2:
The connection between trailers is dynamic rather than rigid. The transfer frames and traction bars allow each trailer to rotate independently during turns, enabling the multi-trailer unit to navigate smoothly without compromising steering control. This dynamic connection maintains transportation efficiency while preserving ease of operation.
3Quantity of substance
If multiple tractors tow trailers, then transportation capacity increases, but interference between tractors occurs
Solution Approach 1:
The patent merges multiple trailers into a single unit that can be towed by one tractor, eliminating the interference that occurs when multiple tractors operate simultaneously. The connected trailers move together in coordination, preventing the road blockage and interference problems that arise when multiple independent tractor-trailer units share the road.
Solution Approach 2:
The transfer frame structure can be replicated to connect additional trailers to the same tractor. Instead of adding more tractors, the system copies the transfer frame and traction bar connections to expand capacity. This allows one tractor to tow multiple trailers without creating interference, as all trailers are coordinated through the shared connection structure.

AI summary
The invention relates to a double-traction transfer vehicle used for trailers, comprising a front traction mechanism, two traction bars arranged in a cross, and a transfer frame connected with the trailer and provided with a running device, one end of each traction bar near the front traction mechanism is connected to the front traction mechanism by the retractor, and one end of each traction bar near the transfer frame is hinged to the transfer frame, the top of the transfer frame is provided with a saddle for connection to the trailer. The invention can meet the transportation requirements of one tractor pulling multiple trailers, greatly reduce the cost of equipment for vehicle purchase and labor costs, alleviate the road blockage pressure caused by the operation of multiple tractors wherein each tractor only pull one trailer at the same time, and improve the efficiency of the vehicle for transporting goods.
