    • PROBLEM TO BE SOLVED: To form a second vehicle body side connecting part by a simple structure only burring a lower half body extension part of an arm body, in an L-shaped suspension arm provided with a wheel support, a first vehicle body side connecting part, and a second vehicle body side connecting part at an end of the arm body in the intermediate part, and at the other end, respectively. SOLUTION: The arm body A includes an upper half body AU formed into a cross-sectional reverse U-shape, and a lower half body AL formed into a shape for closing an open end of the upper half body AU by pressing a plate and welded w1 to internal surfaces of a pair of side walls 2 of the upper half body AU. The lower half body AL at the other end of the arm body A is extended longer outward as compared with the upper half body AU. In an extension part ALe, an upward and cylindrical bush support P2 is integrally formed by burring so that the extension part ALe becomes the second vehicle body side connecting part AF2. An outer peripheral surface closer to the intermediate part of the arm body A of the bush support P2 is abutted and welded to an outer end face of the upper half body AU. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:为了通过简单的结构形成第二车体侧连接部,仅在设置有车轮支撑件的L形悬架臂中仅将臂本体的下半体延伸部分翻边,第一车辆 主体侧连接部和第二车身侧连接部,分别位于臂体的中间部的端部,另一端。 解决方案:臂体A包括形成为横截面U形的上半体AU,以及下半体AL,其形成为通过按压将上半身AU的开口端封闭的形状 将板W1焊接到上半身AU的一对侧壁2的内表面。 与上半身AU相比,臂体A的另一端的下半体AL向外延伸。 在延伸部分ALe中,向上和圆柱形的衬套支撑件P2通过翻边一体地形成,使得延伸部分ALe变成第二车体侧连接部分AF2。 更靠近衬套支撑件P2的臂主体A的中间部分的外周表面被接合并焊接到上半身AU的外端面。 版权所有(C)2010,JPO&INPIT

    • PURPOSE:To secure a proper strength and reduce the whole weight of the captioned apparatus by forming two arm members by bending each plate material and forming an A-figure-shaped suspension lower arm through mutual superposition and welding, in a double wishbone-type suspension apparatus. CONSTITUTION:The first arm member 21 which is equipped with an upper wall part 21a having a concaved part 21i at a part, side wall parts 21b and 21c, horizontal flange parts 21d and 21e, tilt sidewall part 21f, and a flat-plate-shaped extension part 21g is formed by bending a plate material. Similarly, the second arm member 22 which is equipped with an upper wall part 22a, side wall parts 22b and 22c, horizontal flanges 22d and 22e, and a reinforcing wall part 22h is formed by bending a plate material. The second arm member 22 is superposed onto the first arm member 21 at a ball-joint installation part 23 and joined through welding. With such constitution, the joint part is formed into double structure, and the rigidity of the rear side part where strength is necessary is improved because of closed sectional structure, and the front side part where strength is unnecessary is formed into a simple structure and made lightweight.
    • 目的:为了确保适当的强度,并通过弯曲每个板材形成两个臂构件并通过相互叠加和焊接形成一个A形形状的悬挂下臂,确保标题装置的整体重量,在双叉骨型悬架 仪器。 构成:第一臂构件21,其具有在一部分具有凹部21i的上壁部21a,侧壁部21b和21c,水平凸缘部21d和21e,倾斜侧壁部21f和平板状部21f。 通过弯曲板材形成形状延伸部21g。 类似地,通过弯曲板材形成配备有上壁部22a,侧壁部22b和22c,水平凸缘22d和22e以及加强壁部22h的第二臂构件22。 第二臂构件22在球接头安装部23处叠置在第一臂构件21上,并通过焊接而接合。 通过这种结构,接合部形成为双重结构,由于闭合的截面结构,提高了需要强度的后侧部的刚性,并且将不需要强度的前侧部形成为简单的结构, 轻巧。
