VEHICLE WHEEL Russian patent published in 1999 - IPC

FIELD: transport engineering. SUBSTANCE: vehicle wheel has rim with flanges, central hub part, spokes connecting rim with hub with thickness and height of spokes increasing in direction towards hub and with side surfaces of each pair of spokes made to arc and mates to each other and with surfaces of hub over circumference with center in plane passing through bisector of angle between adjacent spokes. Side surfaces of spokes are mated with hub surface over arcs of circumference with radial alternating in value. Arcs of circumference of inner side surfaces of pairs of spokes are mated with surface passing through points equally spaced on rim at a distance equal to 0.4-0.6 of spoke minimum thickness from axis, and points located on spoke axis within the limits from hub center to circumference passing through centers of arcs of circumferences conjugating side outer surfaces of pairs of spokes with hub surface. Outer side surfaces of pairs of spokes are conjugated with surface passing through point of contact of arcs of circumferences conjugating outer side surfaces of spokes with hub surface and point located on rim at a distance equal to 0.3-0.5 of spoke minimum thickness from its axis. EFFECT: increased rigidity of wheel rim, enhanced external appearance of wheel. 3 dwg
