FIELD: machine building.
SUBSTANCE: present invention relates to wheel rim and method of its fabrication, intended for use on agricultural and construction vehicles. Central hub disc on external periphery comprises several tabs, protruding in direction from its center. Second hub disc on its inner periphery also comprises several tabs, projecting to hub disk center. Tabs have such shape that each of them enters between other tabs, and are equipped with holes arranged at equal pitch on periphery of circumferences with same diameter and at right angle to tabs. Second hub disc and central hub disc can be made from one corresponding material workpiece, preferably from steel plate, wherein after separation and rotation of two parts their tabs are superimposed. Then two parts of hub disc are connected with bolts through holes made in tabs.
EFFECT: possibility of wheel rim adjustment for wheel track different width while reducing metal consumption and reducing number of operations during its manufacture.
