    • A stress distribution state is improved and a better design is realized.A coil spring 1 has a spring wire 3 that is wound in a coil shape and whose sectional outer basic shape is circular. Between coil inner and outer diameter sections 5 and 7 of a sectional outer shape of the spring wire 3, flat faces 9 and 11 are formed so that coil portions adjacent to each other in the direction of a coil axis 4 are stabilized when they are brought into contact with each other. A flattening T/W of the sectional outer shape with the flat faces 9 and 11 in the coil axis direction is set so that a stress ratio is equal to or lower than a stress ratio of a coil spring whose sectional outer shape is circular. The flat faces 9 and 11 stably receive load and shorten a solid length in a tightly compressed state. This is advantageous in designing a spring having a longer stroke and lower rigidity. Better stress distribution in a circumferential direction of the sectional circumferential shape improves the uniformity of stress distribution.
    • 应力分布状态得到改善,实现了更好的设计。 螺旋弹簧1具有缠绕成线圈形状并且其截面外基本形状为圆形的弹簧丝3。 在弹簧丝3的截面外形的线圈内外径部分5和7之间,形成平面9和11,使得在线圈轴线4的方向上彼此相邻的线圈部分被固定时 彼此接触。 平面9和11在线圈轴方向上的截面外形的扁平T / W被设定为应力比等于或小于截面外形为圆形的螺旋弹簧的应力比。 平面9和11稳定地承受负载,并在紧压缩状态下缩短固体长度。 这在设计具有较长行程和较低刚度的弹簧方面是有利的。 在圆周方向圆周方向上的应力分布更好,提高了应力分布的均匀性。
