Adjustable Tractor Coupling for Stable Goods Carrier Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tractors face safety hazards during the transfer of goods due to the inability to adjust the relative position between the goods carrier and the tractor, leading to issues with center of gravity deviation and reduced friction, resulting in instability while towing or pushing the carrier.
Innovation Solution
A tractor design featuring a rotatable power wheel and an adjustable connecting assembly that allows the goods carrier to be positioned optimally relative to the tractor, ensuring the center of gravity is aligned for stable towing and preventing slippage by moving the connecting assembly along the traveling direction of the tractor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the center of gravity of the goods carrier is close to the tractor, then the tractor is stable during pushing, but the friction between power wheel and ground decreases causing slippage
Solution Approach 1:
The connecting assembly can be adjusted along the traveling direction to change the position of the goods carrier relative to the power wheel. When pushing operations are required, the assembly can be positioned to optimize the load distribution, ensuring sufficient friction force between the power wheel and ground while maintaining tractor stability.
2Device complexity
If the relative position between goods carrier and tractor is fixed, then the structure is simple, but the tractor cannot adapt to different operational conditions
Solution Approach 1:
The connecting assembly incorporates movable components including a bearing seat that can slide along guides and a connecting component with adjustable positioning. This dynamic structure allows the goods carrier's position to be adjusted along the traveling direction, enabling adaptation to different operational conditions such as towing and pushing while maintaining reasonable structural complexity through modular design.

AI summary
A tractor, including a frame, a power wheel and a connecting assembly. The power wheel is rotatably arranged on a bottom of the frame. The connecting assembly is arranged on the frame and is configured to be attached to a goods carrier. The power wheel is rotatable relative to the frame to drive the frame to move, so as to drive the goods carrier to move synchronously through the connecting assembly. The connecting assembly is configured to move back and forth along a first direction relative to the frame to render a relative position between the goods carrier and the frame adjustable along the first direction. The first direction is a travelling direction of the tractor.
