VEHICLE WHEEL Russian patent published in 2007 - IPC B60B3/06 

FIELD: plastic metal working.

SUBSTANCE: invention can be used at technological working of design of vehicle wheels optimum at manufacture of wheel blanks from light alloys by hot die forging. Wheel has hub, disk part and rim in form of solid of revolution limited from inner side in zone adjoining disk part by two surfaces of rotation with straight-line generatrixes, and with toroidal surfaces tangential, each, to one of surfaces of disk part and to one of said surfaces of rotation. Disk part is provided with ports limited by parts of surface of rotation in zone adjoining the rim. The last of indicated surfaces of rotation is made conical. Acute angles in plane passing through wheel axis between generatrix of said conical surface and each of straight-line generatrixes of two other said surfaces of rotation is less than acute angle between these two surfaces of rotation.

EFFECT: reduced to minimum mass of wheel.
