Forestry Tyre Tread Blocks for Track Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pneumatic tires used in forestry machines face damage from rough terrain, stones, tree stumps, and continuous tracks, which wear down the tires and can be dislocated, leading to suboptimal traction and increased wear.
Innovation Solution
A pneumatic tire design featuring a ground-engaging tread section with obliquely oriented primary and secondary tread blocks that provide protection and support for continuous tracks, preventing lateral movement and enhancing traction, along with a method for installing these tires on forestry machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a continuous track is placed on the tyre to improve traction, then the traction capability is improved, but the track may dislocate or project parts may damage the tyre
Solution Approach 1:
The tread section incorporates specific geometric features (shoulder regions, oblique surfaces, and support elements) at localized positions where the track contacts the tyre. These local structural modifications provide targeted support to prevent track dislocation while maintaining overall tyre functionality and traction performance.
2Productivity
If a tyre chain is used to improve traction, then the traction capability is improved, but the tyre chain may dislocate when the tyre is used in rough terrain
Solution Approach 1:
The tread section includes specifically designed geometric features such as shoulder regions and support elements positioned at locations where the tyre chain contacts the tyre. These local structural features provide stabilization to keep the tyre chain in place during operation on rough terrain while maintaining traction effectiveness.
3Productivity
If the tread blocks are oriented obliquely to enhance traction, then the traction capability is improved, but the structural complexity of the tread section increases
Solution Approach 1:
The tread section is divided into multiple discrete tread blocks arranged in circumferential rows, with each block independently oriented at oblique angles. This segmentation allows the complex oblique orientation to be achieved through simple repetition of standardized block units, making the complex geometry manufacturable and maintainable while delivering enhanced traction through the cumulative effect of multiple angled surfaces.

AI summary
A pneumatic tyre (100) for forestry use, comprising a ground-engaging tread section (10) including a series of secondary tread blocks (24), each secondary tread block (24) being in a tread groove (38) between two consecutive primary tread blocks (20). The secondary tread block (24) extends radially from a tread groove bottom (22) to a height (H2) that is reduced with respect to the height (H1) of the radially outermost surfaces of the primary tread blocks (20). A radially outermost surface (26) of the secondary tread block (24) provides a protecting surface adapted to safeguard the tread groove bottom (22) from a track (200) to be placed on the tread section and a shoulder surface (28) of the secondary tread block (24) provides on a side of the tread section (10) a supporting surface adapted to support the track. An end of the secondary tread block may form a step (30) adapted to support a tyre chain (500) to be placed on the tread section.
