What role does a damper play in a car?

The working principle of the damper is to fill an airtight pressure cylinder with inert gas or oil gas mixture, making the pressure in the chamber several times or dozens of times higher than the atmospheric pressure. The pressure difference generated by the cross-sectional area of the piston rod being smaller than the cross-sectional area of the piston is used to achieve the movement of the piston rod. In this article, we will learn about the role of dampers in automobiles?

Dampers have obvious advantages over ordinary springs: relatively slow speed, small dynamic force changes (typically within 1:1.2), and easy control; The disadvantages are that the relative volume is not as small as the coil spring, the cost is high, and the service life is relatively short.

According to its characteristics and application fields, dampers are also known as support rods, angle adjusters, pneumatic rods, dampers, and so on. According to the structure and function of dampers, there are several types of dampers: free type damper, self-locking damper, traction damper, random stop damper, swivel chair damper, pneumatic rod, damper, etc. At present, this product is widely used in the fields of automobile, aviation, medical devices, furniture, machinery manufacturing, etc.

Purpose of damper:

A spring made using the compressibility of air in a closed container. The characteristic curve of its deformation and load relationship is a curve, which can be designed and calculated according to needs. The damper can maintain its natural frequency unchanged under any load, withstand both radial and axial loads, and transmit a certain amount of torque. Different bearing capacities can be obtained by adjusting the internal pressure. There are many structural forms of air dampers, including bladder type and membrane type, commonly used in vehicle suspension and vibration prevention systems for mechanical equipment.
