Do you know the three principles of an air spring?
First principle: air spring design principle:
An air spring is a spring made of the compressibility of the air in the air spring.According to the air spring deformation and load curve needs, can design a set of curve, but in the design process, should pay attention to the deformation of rubber parts and surrounding parts should have enough clearance.
Second principle: principle of action:
The air spring is filled into the compressed air in a sealed container and its elastic effect is achieved by the compressibility of the gas.Due to the ideal nonlinear elastic characteristics of the air spring, the height of the car body does not change with the change of load or load after adding the height adjustment device. If riding comfort is needed, the spring stiffness can be reduced accordingly. Meanwhile, the structure of the air spring suspension becomes complex and the manufacturing cost is high.
Fourth principle: working principle:
The working principle of the air spring is to fill the closed pressure cylinder with inert gas or mixture of oil and gas, so that the pressure in the chamber can be several times or several times higher than the atmospheric pressure, and then the cross-sectional area.The length of the piston rod is less than the cross-section of the piston.This area and the resulting pressure difference affect the movement of the piston rod.Because of the fundamental difference in principle, the gas spring has obvious advantages over the ordinary spring: the speed is relatively slow, the dynamic change is very small, easy to control;Disadvantages are relatively large size and high cost.Life is relatively short.
