RU95108811A - Wide cross-section tyre wheel - Google Patents

Abstract

FIELD: transport engineering; wheels for light snow-bod vehicles on tubeless wide cross- section low-pressure pneumatic tyres. SUBSTANCE: wheel has disc 1, detachable side rings 2 and base of rim 3 with well in its central part. Base of rim 3 is made in the form of two thin-walled truncated cones 5 and 6 welded by smaller section bases to cylindrical section of disc 1 by hermetically sealing seams 7 and 8, and directed opposite to direction of cones of seating flanges coupled with the cones. The deepest portion of base of rim 3 is formed directly by section 4 of disc 1. Flanges 11 are secured on periphery ends of bases of rim 3. Conical seating flanges 12 intended for mounting tyre beads are made integral with flanges 11. Thickness of flanges 11 is 2.0-2.5 fold than that of cones 5 and 6 of rim base. EFFECT: increased reliability and service life of wheel, improved manufacturability of wheel; in case of small scale production at preservation of light weight and strength of wheel required for its floatability. 2 cl, 1 dwg

Изобретение относится колесам транспортных средств, преимущественно легких снегоболотоходов на бескамерных широкопрофильных пневматических шинах низкого давления. Цель изобретения - повышение надежности и долговечности колеса, а также повышение его технологичности в условиях мелкосерийного производства при сохранении легкости и прочности, необходимых для обеспечения плавучести. Колесо содержит диск 1, съемные бортовые кольца 2 и основание обода 3, углубленное в центральной своей части. Основание обода 3 выполнено в виде двух тонкостенных усеченных конусов 5 и 6, своими меньшими основаниями приваренных герметичными швами 7 и 8 к цилиндрическому участку 4 диска 1 и направленных противоположно направлению конусов связанных с ними посадочных полок 12. Наиболее углубленная часть основания обода 3 образована непосредственно участком 4 диска 1. На периферийных концах основания обода 3 закреплены фланцы 11. Конические посадочные полки 12 для установки бортов шин выполнены заодно с фланцами 11. Толщина фланцев 11 в 2,0 - 2,5 раза превышает толщину конусов 5 и 6 основания обода.The invention relates to wheels of vehicles, mainly light snow and swamp vehicles on tubeless wide-profile pneumatic low-pressure tires. The purpose of the invention is to increase the reliability and durability of the wheel, as well as to increase its manufacturability in small-scale production while maintaining the lightness and strength necessary to ensure buoyancy. The wheel contains a disk 1, removable side rings 2 and the base of the rim 3, recessed in its central part. The base of the rim 3 is made in the form of two thin-walled truncated cones 5 and 6, their smaller bases welded with sealed seams 7 and 8 to the cylindrical section 4 of the disk 1 and directed opposite to the direction of the cones of the associated landing shelves 12. The most recessed part of the base of the rim 3 is formed directly by the section 4 disks 1. At the peripheral ends of the base of the rim 3, flanges are fixed 11. The conical landing flanges 12 for mounting the tire beads are made integral with the flanges 11. The thickness of the flanges 11 is 2.0 - 2.5 times greater than t lschinu cones 5 and 6, the base rim.
