货车一边的吊耳跟钢板一直坏是怎么了？
回答：开过货车的都知道。东风的梭式(自由式)钢板吊耳是最舒服,并且最不容易断钢板的。 梭式钢板吊耳好处在于钢板可以随自由伸缩,缺点就在于后吊耳是自由式叶片弹簧悬挂是一种古老的车辆悬挂结构，吉普陆巡等最早的产品上就能找到叶片弹簧的身影，现在大部分的卡车跟很多SUV依然在使用叶片弹簧技术。钢板吊耳夹角It’s good to understand the basics of leaf springs when it comes time to modifying orlifting your truck foroff road use.  Replacement leaf spring shackles are an inexpensive method for increasing ground clearance.我们不难理解为什么钢板弹簧会成为提升或改造车辆越野性能的基础。更换更长的钢板吊耳是一种简单廉价的举升方法。One of the most commonly asked questions is:How much lift will longer shackles yield?  Every 1″ increased shackle length will result in 1/2″ of lift.  For example:  if your truck has 3.5″factory shackles and you installed 5.5″ long shackles, you’ll gain 1″ of lift(2″ longer shackle x 50% = 1″ lift).  Why do you  only gain 1/2″ lift for 1″ increase inshackle length?  Simple, you’re only lifting 1 side of the spring (ie 50%).大部分人会问：升高多少是合适的？吊耳每升高1英寸，则车辆举升0.5英寸。举例：如果你把自己的卡车吊耳长度从出厂的3.5英寸升高到了5.5英寸。那么你的车辆将被举升1英寸（2”吊耳增加长度×50%=1”举升高度）。为什么你得到的高度只有吊耳增加高度的1/2？其实很简单，因为你只升高了整架钢板的一侧。The other common mistake when replacing leaf springs is proper shackle angle.  Increasing or decreasing your shackle angle will have a dramatic effect on how your suspension functions including: spring flex, compression, handling and ride quality.另一个常见的错误经常发生于更换钢板的带来的吊耳角度变化，不合适的吊耳角度变化会给产生戏剧性的效果：跳动扭曲以及更加糟糕的驾驶体验。不正确的夹角The above picture is an example of poor shackle angle.  As you can see the shackle angle is very low which has several negative effects:  1. Springs bottom out easily over bumps.  2. Soft ride handling on corners.  3. Somewhat limited spring flex.上图就是一个典型的糟糕的钢板吊耳夹角，你可以看到这个钢板吊耳夹角带来的负面影响：1钢板底部被抬高而可能导致碰撞缓冲胶 2转向支撑不足 3缩小了弹簧行程完美的夹角The above picture is an example of proper shackle angle.  Correcting the shackle angle drastically improved the ride handling.这张图片为我们展示了一个良好的钢板吊耳夹角，正确的钢板吊耳夹角能大幅提升驾驶品质。A B两点分别为假设的吊耳固定销的位置，A点会比较硬B点会相对较软理想位置应与钢板垂直。How do you know the correct shackle angle?  This can be achieved by drawing an imaginary line through the middle of both spring eyes and making a 90 degree angle.  The angle can be increased or decreased slightly to change spring rate.如果才能确定最恰当的夹角呢？我们将钢板两头的卷耳为端点生成一条参考线，吊耳的安装角度应与这条线垂直。
