空气弹簧中气囊减震器的运用特点Application characteristics of air bag shock absorber in air spring

首先带大家了解一下气囊减震器的运作原理：气囊减震器属于一种充气型的减震器，是利用气压阻力来实现防震动的一种产品，现在使用的有洗涤设备、洗衣脱水机、游乐设备、旋转木马、造纸机械、皮革震荡机械、震动筛、矿山设备、管道设备、船泊设备、精密设备等工业装备的减震上应用了空气弹簧技术。

First of all, let's understand the operation principle of airbag shock absorber: airbag shock absorber belongs to a kind of inflatable shock absorber, which uses air pREssure resistance to achieve anti vibration. Now there are washing equipment, washing and dewatering machine, amusement equipment, Trojan horse, paper-making machinery, leather vibrating machinery, vibrating screen, mining equipment, pipeline equipment, ship mooring equipment, precision The air spring technology is applied in the damping of industrial equipment such as equipment.

6、性能参数: 常用汽车空气弹簧分为膜式、混合式、袖筒式和囊式四种，其主要零部件是上盖、压板、活塞、止挡、扣环五种，一个封闭系统是由上盖、压板、活塞和胶囊所组成的。

6. Performance parameters: commonly used automotive air springs are divided into four types: membrane type, hybrid type, sleeve type and bag type. The main components are the upper cover, pressure plate, piston, stop and retaining ring. A closed system is composed of upper cover, pressure plate, piston and capsule.

    当密封的空气弹簧中充入压缩气体(气压为0.2-0.7MPa)利用气体的可压缩性实现其弹簧作用。气囊通过利用高度调节阀可以控制囊内气压使空气弹簧的刚度使其具有可调性，当作用在弹簧上的载荷增加时气压升高则弹簧的刚度增大，反之当载荷减少时弹簧内的气压下降同时刚度减小。

    When the sealed air spring is filled with compressed gas (the air pressure is 0.2-0.7mpa), the compressibility of the gas is used to realize the spring effect. The air pressure in the air bag can be controlled by using the height regulating valve to make the stiffness of the air spring adjustable. When the load on the spring increases, the air pressure increases and the spring stiffness increases. On the contrary, when the load decreases, the air pressure in the spring decreases and the stiffness decreases.
