LARGE, MEDIUM LIGHT ALLOY WHEEL

Japanese Patent JP3434618

B2

PURPOSE: To improve fatigue strength in spite of being manufactured by casting by connecting a hub installing part and a curved part to each other through an inclined wall part inclined inside in the wheel shaft direction to a radial directional extension line of the hub installing part.
CONSTITUTION: A disk part 12 has an inclined wall part 21 between a hub installing part 14 and a curved part 15, and connects them to each other through it. The inclined wall part 21 is composed of a wall part inclined by an angle θnot less than 35° inside in the wheel shaft direction to a radial directional extension line 22 of the hub installing part 14, and is composed of a short wall extending in a straight line shape, and is integrally connected to the hub installing part 14 on one end, and is integrally connected to the curved part 15 on the other end. Since a wheel 11 has the inclined wall part, a section modulus becomes large in a part of the inclined wall part 21, and as a result, the hub installing part 14 is reinforced by a highly rigid ring in an outer peripheral part, and flexural rigidity of the hub installing part 14 is improved, and since a very near part of a bolt hole 17 exists in the vicinity of the inclined wall part 21, it is reinforced in the circumferential direction by an effect of the inclined wall part 21.
