に断面Ｈ形となつている。 The knuckle arm 3 consists of a straight portion 11 extending inward from the center boss 2 toward the center of the vehicle body, and a curved portion 12 following the straight portion 11 and curving in an arc shape toward the outside of the vehicle body. Grooves 15 and 16 are provided on the inner surface 13 and outer surface 14 of the straight portion 11, respectively, and the cross section is H-shaped as shown in FIG.

ながら荷重に十分に耐えることができる。 The Knuckle 1 is made from a bar-shaped steel material and undergoes hot processing to sequentially form the Natsutal arm 3, tie rod arm 4, and king pin boss 5.
Grooves 15 and 16 are formed on the inner and outer surfaces 13 and 14 of the product before it is bent into a predetermined shape. However, if there are grooves in the bent portions, the thin parts that make up the grooves are easily distorted, making it difficult to maintain the predetermined cross-sectional shape. There will be variations in the strength of the Therefore, in the present invention, grooves 15 and 16 are provided only in the straight portion 13, and no grooves are provided in the curved portion 12, so that there is no distortion in the H-shaped portion even when bending is performed, and the bending process is easy. Not only that, but we were able to obtain a product with no variation. In addition, the Y-Y direction in Figure 3, which is strong against bending loads of the H-shape, is made to match the direction of the bending loads applied to the knuckle arm 3 shown by F in Figure 2, so it can withstand the load sufficiently despite being lightweight. be able to.
（発明の効果）
ナツクルアームの内外面に溝をつけてＨ形とし
たため、ナツクルの重量が減少し車両の軽量化に
役立ち、溝が曲線部分のみに設けられるので、曲
げ加工が容易であり量産に都合がよい。(Effects of the invention) Grooves are added to the inner and outer surfaces of the Knuckle arm to form an H-shape, which reduces the weight of the Knuckle arm, helping to reduce the weight of the vehicle.Since the grooves are provided only on curved parts, bending is easy and mass production is possible. convenient.
