Non-pneumatic Tire Securing Fastener with Position Fixing Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional non-pneumatic tires face challenges with poor stretching performance of high-strength fiber bundles or steel wires, leading to tripping risks and relative sliding movement issues between the tire and rim, which complicates maintenance.
Innovation Solution
A tire member with a mounting protrusion and securing notches, combined with a securing fastener featuring a position fixing groove and holes, securely fixes the tire to the rim, reducing sliding movement and enhancing maintenance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-strength fiber bundles or steel wires are used to fix the non-pneumatic tire inside the rim, then the tire can be secured to the rim, but the stretching performance is poor causing tripping risks and relative sliding movement between tire and rim
Solution Approach 1:
The mounting protrusion is segmented into multiple position fixing grooves (4-100 pieces) uniformly distributed in the circumferential direction, allowing the securing fastener to engage at multiple discrete positions, providing both security and flexibility for stretching adjustments
Solution Approach 2:
A securing fastener is introduced as an intermediary component between the tire member and the rim. The fastener features a support portion that fits into the position fixing groove and a blocking portion that prevents detachment, while allowing controlled movement through the securing holes
2Reliability
If high-strength fiber bundles or steel wires are used to fix the non-pneumatic tire inside the rim, then the tire can be secured to the rim, but relative sliding movement between the tire and rim occurs
Solution Approach 1:
The mounting structure transitions from a static fixed connection to a dynamic adjustable system. The securing fastener can move along the mounting protrusion through the securing holes, allowing the tire position to be adjusted while maintaining secure fixation, thus preventing unwanted sliding while enabling controlled movement
Solution Approach 2:
The continuous mounting surface is segmented into discrete position fixing grooves with securing holes, creating a series of controlled engagement points that guide the securing fastener, preventing uncontrolled sliding while allowing position adjustments
3Reliability
If high-strength fiber bundles or steel wires are used to fix the non-pneumatic tire inside the rim, then the tire can be secured to the rim, but detachment risks and maintenance complexity increase
Solution Approach 1:
The securing system is divided into separable components: the tire member with mounting protrusion, the securing fastener with blocking portion, and the rim with securing notches. This modular design allows the fastener to be easily removed and reinstalled, simplifying maintenance and replacement operations
Solution Approach 2:
The securing function is extracted from the tire structure itself and implemented through a separate, removable securing fastener. This allows the fastener to be taken out for maintenance or replacement without damaging the tire or rim, reducing maintenance complexity

AI summary
A tire member of a non-pneumatic tire is provided. An inner circumference of the tire member is provided with a mounting protrusion. Securing notches for securing the tire member to a rim are provided at two sides of where the mounting protrusion joins the tire member. A position fixing groove is provided at an inner circumference of the mounting protrusion. The position fixing groove has an annular structure; alternatively, the position fixing groove has an arc structure, and a plurality of the position fixing grooves having the arc structure are uniformly distributed at the inner circumference of the mounting protrusion in a circumferential direction. Two side walls of the position fixing groove are provided with several securing holes below the securing notches, respectively. The securing holes pass through the side walls of the position fixing groove, and partially coincide with securing notches at an outer side.
