The role of the shock absorber, the working principle of the shock absorber structure

I believe that many riders know that too soft a shock absorber will cause the body to jump up and down, and too hard will accelerate the damage of the shock absorber spring. At the same time, direct impact on the road will increase the discomfort of the people in the car. Let's take a closer look at the function and working principle of the lower shock absorber.

About the role of shock absorbers

We need to distinguish between the shock absorber and the spring, because as far as the shock absorber is concerned, its function and the spring can be said to be opposite to each other.

When the vehicle is running, the damping spring is mainly used to absorb bumps and vibrations caused by uneven road surfaces.However, the spring as elasticYuanWhile absorbing and filtering road bumps and vibrations, it also produces reciprocating bounce motion. The main function of the shock absorber is to suppress the repeated bounce of the shock absorber spring after absorbing various impacts brought by the road surface, so as to accelerate the attenuation of the natural vibration of the spring and provide better driving comfort for the vehicle.

The working principle and structure of the shock absorber

As the current mainstream uses hydraulic shock absorbers, we will introduce the principle and structure of hydraulic shock absorbers in the following order.

The hydraulic shock absorber is mainly composed of:Upper support, piston rod, hydraulic oil, piston, oil storage cylinder, pressure cylinder, bottom valve, lower support and flow valvecomposition. The upper support is integrated with the piston and the piston rod and is connected to the vehicle body; the lower support is integrated with the pressure cylinder and is connected to the swing arm of the frame.

When the vehicle undergoes relative movement due to vibration, the piston inside the shock absorber will move up and down, and the hydraulic oil inside the oil cavity will flow from one cavity to the other cavity repeatedly from the through valve on the piston. With the friction between the wall of the flow valve hole and the oil and the internal friction between the oil molecules form a damping force on the vibration generated, the vibration energy is converted into heat energy and dissipated into the atmosphere.
