Horizontal Tire Changer With Adjustable Hook and Pressing Wheel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire disassembling machines cause inner tube damage and are inefficient for large tires due to fixed relative positions between disassembling hooks and pressing wheels, limiting their ability to handle large tubed and tubeless tires effectively.
Innovation Solution
A combined tire-disassembling device with adjustable shafts and a horizontal tire changer that allows independent movement of disassembling and assembling hooks and pressing wheels, utilizing oil cylinders for precise control and a sliding platform for tire disassembly, enabling handling of large tires up to 2500 mm diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the disassembling head is an integral structure with fixed positions of hook and pressing wheel, then the structure is simple and easy to manufacture, but the relative position between hook and pressing wheel cannot be adjusted, causing time-consuming operation and inner tube damage
Solution Approach 1:
The disassembling head is divided into separate components: the first shaft with pressing wheel and the second shaft with disassembling hook. These segments can move independently relative to each other, allowing adjustment of their positions without rotating the entire disassembling head, thus improving operational convenience while reducing the risk of inner tube damage.
Solution Approach 2:
The patent introduces a dynamic adjustment mechanism where the second shaft can move along the first shaft through an oil cylinder. This dynamic structure allows the relative position between the hook and pressing wheel to be adjusted during operation, eliminating the need to rotate the entire disassembling head and reducing inner tube damage.
2Adaptability or versatility
If the relative position between disassembling mechanism and chuck assembly is fixed with small adjustment range, then the structure is compact, but it cannot meet the needs of disassembly and assembly of large tires
Solution Approach 1:
The patent employs dynamic adjustment mechanisms including the oil cylinder for moving the second shaft along the first shaft, and the sliding platform that can move horizontally. These dynamic structures provide a large adjustable range to accommodate different tire sizes, especially large tractor tires, while maintaining a relatively compact overall structure when not in use.
Solution Approach 2:
The second shaft is nested within the first shaft structure, allowing the disassembling hook to be positioned at various distances from the pressing wheel. This nested configuration enables a large adjustable range without significantly increasing the overall footprint of the device, making it adaptable to different tire sizes.
