Abstract

Zvýšení průjezdnosti pneumatik a produktivity traktorů gři plnění přepravních a polních prací v zónách s různými půdně- ,klimatickými podmínkami spočívá v tom, že elementy běhounu jsou provedeny a rozloženy podle zon běžné plochy tak, že koeficient nasycenosti vzorku protektoru v rovníkové zóně, procházející vnitřními prvky záběrových elementů desénu, tvoří 0,36 až 0,45 s poměry koeficientů nasycenosti ve střední a bocníoh zónách běžná ploohy procházející přes střední a vnější prvky záběrových elementů desenu lje koeficientu nasycenosti v rovníkové zóně jsou rovny 0,85,až l»0 a 0,75 až 0,85, přičemž uvedené zóny tvoří pět stejných po šířce úseků běžné ploohy pneumatiky.Increasing the tire passability and productivity of tractors when performing transport and field work in zones with different soil and climatic conditions consists in the fact that the tread elements are made and distributed according to the zones of the common area so that the saturation coefficient of the tread pattern in the equatorial zone, passing through the inner elements of the engaging elements of the tread, is 0.36 to 0.45, with the ratios of the saturation coefficients in the central and lateral zones of the common area passing through the central and outer elements of the engaging elements of the tread and the saturation coefficients in the equatorial zone being equal to 0.85 to 1»0 and 0.75 to 0.85, with the said zones forming five equal sections of the common area of the tire.

BACKGROUND OF THE INVENTION The tread pattern of a tire, particularly for tractor wheels of a tractor and agricultural machinery, comprising an increased throughput design, in the form of uniformly alternating and angled "oblique-firing" engaging elements, distributed at an alternating angle to the equatorial surface of the tire and comprising a center a zone of conventional surface with maximum saturation of the tread pattern and adjacent thereto from both sides of the central and side zones, characterized in that, in order to increase the throughput of the tire, the productivity of the tractors in the fulfillment of transport and field work in zones with different climatic conditions conditions, the tread pattern saturation coefficient, under the conditions of distribution to a normal flat width of five straight sections, in the equatorial zone form 0.36 to 0.45, and the ratio of saturation coefficients in the middle and side zones of the normal area to the saturation coefficient in the equatorial zone is equal0.85 to 1.0 and 0.75 to 0.85. 259016
