A Guide To Motorcycle Shock Absorber

Motorcycle shock absorber is an essential part for motorcycle. However, many people often overlook it. In this paper, we will introduce you the function of the shock absorber and different types of it.

What Is Motorcycle Shock Absorber?

Shock absorber is an important part of motorcycle. Its main function is to alleviate and attenuate the impact and vibration of motorcycle due to uneven road during driving, and ensure the smoothness and comfort of driving, which is conducive to improving the service life and handling stability of motorcycle.

Classification Of Motorcycle Shock Absorber

There are many classification methods:

1. According to the installation position, there are front shock absorber and rear shock absorber.
2. According to the direction of attenuation force, there are unidirectional shock absorbers and bidirectional shock absorbers.
3. According to the load adjustment type, there are spring initial pressure adjustment type, air spring type and installation angle adjustment type.
4. According to the structural form, there are telescopic tube front * hydraulic shock absorber (which is the most used front shock absorber in motorcycles), rocker shock absorber, rocker lever vertical center shock absorber and rocker lever inclined center shock absorber.
5. According to the working position of the oil cylinder, there are inverted shock absorbers (i.e. the oil cylinder is located above and the piston rod is located below) and positive shock absorbers (the oil cylinder is located below and the piston rod is located above).
6. According to the working medium, there are spring type shock absorbers, spring air damping shock absorbers (due to the limited damping force of air, the damping effect is not ideal, which is generally only used for mopeds with low speed as rear shock absorber), hydraulic damping shock absorber, oil-gas combined front shock absorber and nitrogen filled hydraulic shock absorber.

How To Choose Motorcycle Shock Absorber?

The use time and the ambient temperature are different. Therefore, in order to adapt to various climatic conditions in the motorcycle operation area, most shock absorbers absorb the impact and vibration energy through the flow damping force of oil, and convert it into the heat of oil to dissipate. Therefore, the damping force is closely related to the viscosity of oil, which changes with temperature. The following technical requirements are put forward for shock absorber oil:

Shock absorber oil must have good anti rust and anti-wear effects;

The shock absorber oil should have as little vaporization loss as possible in all the application ranges of motorcycles (including special situations such as high-speed, full load and overload driving), that is, the so-called small vaporization performance;

When the shock absorber oil contacts with air, it must have anti-oxidation stability and anti-oil-gas mixing stability, that is, the so-called good working stability;

The freezing point of shock absorber oil used in China shall not be lower than - 40 ℃. In other words, when the temperature drops to 0 ℃ ~ - 40 ℃ in severe winter, the oil shall not lose fluidity;

The shock absorber oil containing impurities will soon scratch the piston rod or cause the incomplete edge of the oil seal during the driving of the motorcycle, resulting in oil leakage. Therefore, the shock absorber oil must be kept absolutely clean;

Shock absorber oil should not only have good viscosity temperature performance and high viscosity index but also have a low freezing point. When the ambient temperature changes or the temperature of the shock absorber oil itself changes with the extension of working time, the viscosity change of the oil should be very small.

In The End

It is recommended to purchase the absorber from regular manufacturers. CHONGQING KALIDA INDUSTRY CO., LTD is a specialized motorcycle shock absorber supplier, and it has a big motorcycle shock absorber factory.
