    • PROBLEM TO BE SOLVED: To provide an automobile suspension improving ride comfort by lowering the fore-and-aft stiffness of a suspension bush, making a wheel on a steering outer ring side promptly toe in while keeping lateral stiffness, and facilitating a layout. SOLUTION: Right and left trailing arms 10 in a vehicle body fore-and-aft direction are rigidly united by a torsion beam 12 in a vehicular width direction. A wheel attaching portion 11 is provided at a rear end of the trailing arm, and right and left shock absorbers and spring members 13 are provided between the torsion beam or the wheel attaching portion and a vehicle body. A tip end part of the trailing arm is elastically united to the vehicle body by the suspension bush 14. The right and left trailing arms are coupled with each other at tip ends and rear ends by making two beams 10A oppose to each other. The right and left trailing arms are structured to be a flat surface trapezoidal shape wherein a clearance between the two beams is decreased from the tip ends to the rear ends. The trailing arms are deformed in a direction which lateral force acts, and the wheel on the turning outer ring side is displaced in a toe-in direction. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:为了通过降低悬挂衬套的前后刚度来提供改善乘坐舒适性的汽车悬架,使得在转向外圈侧上的车轮立即保持脚趾同时保持横向刚度,并且便于 布局。 解决方案:车身前后方向上的左右拖臂10通过扭矩梁12在车宽方向上刚性地结合在一起。 在后臂的后端设有车轮安装部11,在扭力梁或车轮安装部与车身之间设置有左右的减震器和弹簧部件13。 牵引臂的前端部分通过悬挂衬套14弹性地结合到车身上。左右拖臂通过使两个梁10A彼此相对地在前端和后端彼此联接。 左右拖臂构造成平坦的梯形形状,其中两个梁之间的间隙从顶端减小到后端。 拖臂在横向力作用的方向上变形,并且转向外圈侧的车轮在前后方向上移位。 版权所有(C)2007,JPO&INPIT
