FIELD: transport engineering; wheels of motor vehicles. SUBSTANCE: proposed wheel with at least three spokes has rim with front and rear flanges, central hub portion and spokes connecting rim with hub. Side surfaces of each pair of spokes are made to arc of circumference with center in plane passing through axis of wheel and longitudinal axis of symmetry of third spoke being bisector of angle between two other spokes. Side surface of hub is made in form differing from cylindrical one. Side surfaces of two adjacent spokes are mated with each other and with surface of hub over arcs with radius with center in plane passing through bisector of angle between adjacent spokes. Thickness of spokes is variable, increasing towards hub in axial direction. EFFECT: increased rigidity and reduced weight of wheel. 4 cl, 5 dwg |
