Product Description

Structural diagram and structure of the car shock absorber:
The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface, and is used to counter the torsional vibration of the crankshaft (that is, the phenomenon that the crankshaft is twisted by the impact force of the cylinder ignition). The following is a brief introduction to the structure of the shock absorber.
Shock absorber structure diagram - composition:
The shock absorber is mainly composed of two parts: a spring and a damper. The function of the spring is to support the weight of the vehicle body, while the damper is to reduce the vibration."Damping" in the Chinese dictionary is explained as: "The phenomenon that the object is affected by various resistances during the movement, and the energy is gradually attenuated and the movement is weakened." Dampers are man-made tools for attenuating the motion of an object.
In order to prevent objects from being suddenly impacted, damping has a wide range of applications in our real life, such as the shock absorption system of a car, and the spring door can be slowly closed after being opened, etc.
Shock absorber structure diagram - structure:
The structure of the shock absorber is that the piston rod with the piston is inserted into the cylinder, and the cylinder is filled with oil. There is an orifice on the piston, so that the oil in the two spaces separated by the piston can complement each other. Damping is produced when viscous oil passes through the orifice, the smaller the orifice, the greater the damping force, and the greater the viscosity of the oil, the greater the damping force. If the size of the orifice remains the same, when the shock absorber works at a high speed, excessive damping will affect the absorption of shock.
Shock absorber damping vibration: The shock absorber on the car is required to be able to compress immediately when encountering uneven road surfaces, and the shock absorber cannot be allowed to do strong damping vibration after passing through. Therefore, the shock absorber must be designed with a structure that is easy to compress and rebounds slowly. That is to say, like this memory pillow, it will sag immediately when you sleep, and it will recover slowly when you rebound. The resistance and energy absorption of the oil are relatively strong. If the oil flows out quickly to the upper part of the piston and the interlayer during compression, the compression speed of the shock absorber will be faster; let the oil flow back from the upper part of the piston and the interlayer The slower the return to the core, the slower the rebound. In this way, the shock absorber can be controlled to achieve fast compression and slow rebound, thereby avoiding excessive generation of damping vibration, so that the suspension is not too loose while the vibration is strong. So far, we can adjust the shock absorber by changing the outflow speed and inflow speed of the one-way valve (the number or aperture of positive and negative one-way valves); changing the viscosity of the oil (electromagnetic damping shock absorber); spring rigidity, etc. required degree. What needs to be explained here is that there are various shapes and structures of shock absorbers. What Taizhou Dongna described is a double-barrel (double-wall) structure.
