摘要： The invention provides a method of manufacturing an irregular section tubular body and axle beam. The axle beam has a tubular worked body that has sealed liquid therein and is press-formed by upper and lower press molds. One of the press molds has a convex mold portion to form a concave portion concaved in an axis perpendicular direction at an axial part of the axle beam. The press-forming of the tubular worked body is completed by a one stroke process using liquid pressure that increases as the internal volume of the worked body decreases due to formation of the concave portion. The concave portion extends substantially the length of the axle beam and has a substantially U-shaped or V-shaped cross-section forming a closed and sealed space.

摘要： A suspension arm in which the accuracy of a bush supporting portion is improved. The suspension arm is formed by respectively welding both side portions of an upper plate member and both side portions of a lower plate member to each other, the upper plate member and the lower plate member each having a substantially U-shaped cross-sectional configuration. The bush supporting portion is formed in such a manner that an upper cylindrical portion and a lower cylindrical portion are respectively formed by burring at rear ends of the upper plate member and the lower plate member. Further, clearances are respectively formed between the side portions of the upper plate member and the upper cylindrical portion, and between the side portions of the lower plate member and the lower cylindrical portion. Accordingly, there is no possibility that the heat generated upon welding is directly transmitted to the upper cylindrical member and the lower cylindrical member, so that the accuracy of the bush supporting portion can be improved.

摘要翻译： 一种提高衬套支撑部分的精度的悬架臂。 悬挂臂通过分别将上板构件的两侧部分和下板构件的两侧部彼此分别地形成，上板构件和下板构件均具有大致U形的横截面构造。 衬套支撑部分形成为通过在上板构件和下板构件的后端处通过翻边分别形成上圆柱形部分和下圆柱形部分。 此外，在上板构件和上圆筒部分的侧部之间以及下板构件的侧部和下圆柱部分之间分别形成间隙。 因此，焊接时产生的热量不会直接传递到上部筒状部件和下部筒状部件，从而能够提高衬套支撑部件的精度。

摘要： In a suspension arm formed by press working a plate-shaped member, in a case in which, while a vehicle is traveling, a load is inputted to the suspension arm in a direction intersecting a direction in which the suspension arm swings, at least a region at which a maximum stress is generated is a non-end portion of the plate-shaped member. Accordingly, high rigidity can be ensured without an increase in weight.
