Abstract

Протектор (2) шины (1) для большегрузного автомобиля и шина, снабженная таким протектором, при этом протектор (2) содержит множество разрезов (4), ориентированных по окружности и по ширине, причем каждый из разрезов простирается внутрь протектора на глубину, меньшую средней толщины протектора, при этом каждый разрез (4) продолжен радиально внутрь каналом с боковыми стенками для ограничения, после частичного износа протектора, нового желобка, причем эти боковые стенки соединяются на дне, а каждый разрез связывает между собой множество дренажных колодцев (6), при этом каждый дренажный колодец (6), выполненный в толще протектора, открывается первым отверстием (61) на поверхность (3) качения протектора, отверстием, максимальный размер которого, по меньшей мере, равен двум размерам ширины разреза (4), а вторым отверстием - в канал, причем этот протектор (2) выполнен таким образом, что для каждого разреза (4) общей окружной ориентации выполнен по меньшей мере один дренажный колодец (6), контактирующий в процессе езды, и в продолжение каждого дренажного колодца (6) выступ на дне канала. Отливающий элемент для отливки разреза, описанного выше.
