人類的福音-空氣彈簧使車子保持平穩舒適The gospel of mankind - air spring keeps the car stable and comfortable

隨著科學技術的進步，人們生活質量的提高，同時道路路面質量也在不斷的提高，車輛的速度越來越快。因此，對車輛舒適性的要求自然會提高，彈簧開始慢慢離開乘用車和小型車輛的領域； 另一個金屬彈簧開始慢慢攀升至主導位置-螺旋彈簧。  

With the progREss of science and technology, the improvement of people's quality of life, at the same time, the quality of road surfACE is also constantly improving, and the speed of vehicles is getting faster and faster. Therefore, the requirements for vehicle comfort will naturally increase, and the spring will slowly leave the field of passenger cars and small vehicles; another metal spring will slowly climb to the dominant position - coil spring.

每個人都熟悉螺旋彈簧：像家用玩具一樣小，像傢俱一樣大，它的存在隨處可見。相較於板簧，螺旋彈簧的柔軟度要好得多，但懸架結構卻變得更加複雜。

Everyone is familiar with coil springs: as small as a home toy, as big as furniture, it can be seen everywhere. Compared with leaf spring, the flexibility of coil spring is much better, but the suspension structure becomes more complex.

如前所述，板簧具有車輪定位功能，但是螺旋彈簧卻沒有。因此，我們需要添加一些拉杆以迫使車輪保持在原位。    

As mentioned earlier, leaf springs have wheel alignment, but coil springs do not. Therefore, we need to add some tie rods to force the wheels to stay in place.

隨著螺旋彈簧的普及，獨立懸架已逐漸成為乘用車的主流。獨立懸架和螺旋運動的結合幾乎已經成為汽車領域真誠與友善的代名詞。但是，人類對舒適的追求是無止境的。人們慢慢開始發現螺旋彈簧的缺點：

With the popularity of coil spring, independent suspension has gradually become the mainstream of passenger cars. The combination of independent suspension and spiral motion has almost become the pronoun of sincerity and friendliness in automobile field. However, the pursuit of comfort is endless. People slowly began to discover the shortcomings of coil springs

那是恒定的剛度。實際上，它與板簧相同：帶有板簧的卡車在空的時候會很顛簸，但是在裝載重物之後，車輛在行駛時變得更加靈活。實際上，螺旋彈簧也是如此： 如果彈簧太軟，則在空的時候會很舒服，但是在人滿為患時，汽車將直接倒塌；如果彈簧太硬，到處都是人會很舒服，空車會很顛簸。

That's constant stiffness. In fact, it's the same as leaf springs: trucks with leaf springs can be bumpy when empty, but they become more flexible when loaded with heavy loads. In fact, the same is true of coil springs: if the spring is too soft, it will be comfortable when it is empty, but when it is overcrowded, the car will collapse directly; if the spring is too hard, people everywhere will be very comfortable, and the empty car will be bumpy.

有沒有辦法解決這個矛盾呢？答案是有的，科學家們研究出了一個神物：空氣彈簧。空氣彈簧實際上是一個橡膠氣囊。充滿空氣後，它變得有彈性。您可以把它想象成一個氣球。通貨膨脹壓力越高，難度越大；通脹壓力越低，它就越軟。其道理與輪胎相同。

Is there any way to solve this contradiction? The answer is yes, scientists have developed a miracle: the air spring. The air spring is actually a rubber airbag. When filled with air, it becomes elastic. You can think of it as a balloon. The higher the inflation pressure, the more difficult it is; the lower the inflation pressure, the softer it is. The reason is the same as tire.

可以說這隻是人類的福音。空車時應減少充氣，滿載時應增加充氣，以確保彈簧始終保持***舒適狀態。

It can be said that this is just the gospel of mankind. In order to ensure that the spring always keeps the best comfortable state, the inflation should be reduced when the car is empty and increased when it is fully loaded.
