Tire Running Set with Deformable Adapters for Steering and Kerbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire designs compromise on steering ability and kerbing resistance due to the high extension rigidity of circumferential reinforcing elements, which leads to non-linear responses under vertical and transverse loading.
Innovation Solution
A running set comprising a tire with a mounting rim width of 55% to 80% of the maximum axial width, paired with elastically deformable adapters that provide radial and axial deformations, allowing the bead to move relative to the rim, enhancing steering capability and kerbing resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If circumferential reinforcing elements with high extension rigidity are used in the carcass reinforcement, then transverse flexibility is improved, but steering ability deteriorates due to non-linear response under vertical loading
Solution Approach 1:
The patent changes the mechanical parameters of the reinforcing elements by using a braided structure with specific geometric characteristics (interlacing angle α between 10° and 45°). This braided configuration transforms the rigidity characteristics, providing both transverse flexibility and linear elastic response under vertical loading, thereby resolving the contradiction between stability and ease of operation
Solution Approach 2:
The patent employs a composite reinforcing structure combining radial elements and circumferential braided elements with complementary mechanical properties. The radial elements provide radial strength while the braided circumferential elements provide transverse flexibility with linear response characteristics, together resolving the contradiction between transverse flexibility and steering ability
2Ease of operation
If the rim width is reduced to improve certain tire properties, then other properties such as steering ability are improved, but kerbing resistance deteriorates
Solution Approach 1:
The patent changes the geometric parameters of the reinforcing structure (braided configuration with interlacing angle) to achieve both improved steering ability and maintained kerbing resistance, resolving the contradiction between ease of operation and strength
3Stability of the object's composition
If circumferential reinforcing elements are used to stabilize the secondary structure, then transverse flexibility is improved, but the tire exhibits non-linear response under transverse loading affecting steering precision
Solution Approach 1:
The patent optimizes the geometric parameters of the braided circumferential elements (interlacing angle, braid tightness) to achieve linear elastic response under transverse loading while maintaining secondary structure stability, thereby resolving the contradiction between structural stability and steering precision
