气囊减震器有哪些优点What aRE the advantages of airbag shock absorber

汽车上所采用的空气弹簧可以大致分为自由膜式、混合式、袖筒式和囊式空气弹簧，这些空气弹簧与金属弹簧相比具有质量小、舒适性好、耐疲劳、使用寿命长等优点同时具有减震和消音作用。而气囊减震器广泛用于汽车、火车及冲床等各种机械上，下面我们就一起来看下气囊减震器的优点。

The air springs used in automobiles can be roughly divided into free film type, hybrid type, sleeve type and bag type air springs. Compared with metal springs, these air springs have the advantages of small mass, good comfort, fatigue resistance, long service life, etc., and have the functions of shock absorption and noise elimination. Airbag shock absorber is widely used in automobiles, trains and presses and other machinery. Let's take a look at the advantages of airbag shock absorber.

气囊减震器的优点如下：

The advantages of the airbag shock absorber are as follows:

1、可以根据需要将它的特性线设计成比较理想的曲线具有非线性特性；

1. Its characteristic line can be designed as ideal curve according to the need, which has nonlinear characteristics;

2、气囊减震器的刚度随载荷而变，在任何载荷下自振频率不变使弹簧装置具有几乎不变的性能；

2. The stiffness of the airbag shock absorber changes with the load, and the natural frequency remains unchanged under any load, so that the spring device has almost constant performance;

3、吸收高频振动和隔声的性能好；

3. It can absorb high frequency vibration and sound insulation;

4、通过高度控制阀可使空气弹簧的工作高度在任何载荷下保持一定，同时也可使弹簧在同一载荷下具有不同的高度有利于适应多种结构上的要求；

4. Through the height control valve, the working height of air spring can be kept constant under any load, and the spring can have different height under the same load, which is conducive to meet the requirements of various structures;

5、空气弹簧的刚度可根据需要借助于改变附加空气室的容积进行选择,而且可选择得很低；

5. The stiffness of the air spring can be selected by changing the volume of the additional air chamber according to the needs, and the selection can be very low;

6、同一空气弹簧能同时承受轴向和径向载荷也能传递扭矩,可以对内压力进行调整从而得到不同的承载能力,所以说气囊减震器可以满足多种载荷的需要；

6. The same air spring can bear axial and radial load at the same time, and also can transfer torque. The internal pressure can be adjusted to obtain different bearing capacity. Therefore, the airbag shock absorber can meet the needs of various loads;

7、在空气弹簧本体和附加空气室之间设一节流孔能起到阻尼作用,但是如果孔径选择适当可不设减震器。

7. The damping effect can be achieved by setting a throttle hole between the air spring body and the additional air chamber, but if the hole diameter is selected properly, the shock absorber can not be set.
