AI Technical Summary
Technical Problem
Existing heavy-load tires, particularly those for construction and mining vehicles, suffer from insufficient cooling of the belt due to inadequate airflow through widthwise grooves, leading to heat accumulation and tire failure.
Method used
The tire design incorporates widthwise grooves with air introduction grooves and paddle groove portions featuring a straight section, slanted section, and arc-shaped bottom section, along with air guide grooves and notches, to enhance airflow and cooling efficiency.
Benefits of technology
The enhanced airflow through the grooves effectively dissipates heat, reducing the risk of tire failure by improving the cooling effect of the belt and maintaining wear resistance.
