IMPROVING OF TECHNICAL CHARACTERISTICS OF AGRICULTURAL TRAILER TIRES

EDN:NYSBXT

Abstract

A problem of import substitution is acute not only for the raw material base for the tire industry, both for the military-industrial complex and for the national economy, but also for products in general due to the current geopolitical situation. The problem of improving the technical characteristics of tire products to the level of leading manufacturers in Europe and the USA with the maximum use of domestic raw materials, taking into account the preservation of the level of product quality is considered in the article. An overview of the results of investigations of LLC “NORTEC”, carried out as part of import substitution for agricultural tires for trailers of the RUF-2 type, is given. The influence of the use of anid cords instead of the previously used nylon cords in the main load-bearing structural elements on the tire performance was established. Also, to improve the quality of products, the formulations of rubber compounds have been revised in terms of increasing the proportion of natural rubber to reduce the risk of tire destruction in the shoulder area when working with overload and at low pressure relative to the norm, which is most important for trailer tires.

Based on the results of laboratory tests, it was established that the developed design of an agricultural tire with improved technical characteristics for trailers fully complies with the requirements of the Russian Federation standards and has improved performance characteristics with the elimination of the previously existing problem - tire destruction in the shoulder area
