But the dazzling variety of shock absorption is also irritating to the scalp, and various types of shock absorption can also cause various ills. Which type is the one that suits your needs? Today, from the most basic point of view, let's take a look at the shock absorption of motorcycles.
Shock absorption
Like a car, shock absorption is a device that carries the frame on the tire. The main function is to match the tires, cushion the bumps caused by uneven road surface, reduce the vibration of the body and provide driving comfort. In addition, keep the tire between the ground and the ground. The contact can make the tire and the ground fit tightly when bumping the road, generating enough driving force to avoid losing tire grip and vehicle tracking.
In fact, for motorcycles, in addition to the above two points, there is a difference between the car and the important role of the car, that is, the shock absorption configuration of the motorcycle has a great impact on the control. After all, the motorcycle is basically a vehicle that is tilted to change direction. . In the cornering, due to the attitude of the motorcycle body, the pressure on the left and right sides is not equal, so in addition to providing sufficient supporting force, it is necessary to adjust the balance on both sides of the motorcycle to ensure the stability of the vehicle's curve. performance.
Damping type
At present, the main types of shock absorption in the motorcycle market are mainly divided into: spring shock absorption, hydraulic shock absorption and more advanced electronic shock absorption.
1 spring shock absorption
Spring shock absorption is the most traditional and most intimate type, and this type of shock absorption is still used in most models on the market. Spring shock absorption is the compression deformation of a high-strength spring with a set number of pounds to absorb the impact of the ground and achieve shock absorption. The extent of this shock absorption is determined by the spring-matched damper.
As the name implies, the damper intervenes in the deformation process of the spring to control the compression, rebound speed and strength of the spring. The kinetic energy of the damper compressing the spring is compressed by the internal piston and flows into the other cavity through the wall of the hole. It is converted into heat energy by the friction between the oil molecules, and then converted into the atmosphere through the air.
2 hydraulic shock absorption
Hydraulic shock absorption can be seen as an enhanced version of the damper, by changing the design of the internal bore and enhancing the viscosity of the oil for shock absorption purposes. In addition to oil, some types of shock absorbers are filled with gas instead of oil.
For a simple example, just plug one end of the medical syringe (of course, remove the needle), and there will be obvious resistance when pushing and pulling.
3 electronic shock absorption
With the development of technology, electronic suspension has also been used in more and more high-end models. For example, the recently topical Honda Fireblade is equipped with Ohlins active electronic damping on its SP performance version.
Electronic damping is to adjust the internal magnetic field by controlling the magnitude of the current to achieve the effect of changing the damping. And through the intervention of the computer, the electronic shock absorber can quickly calculate the current body posture, engine working conditions and driving habits, and directly intervene the damping of the shock absorber to help the driver get better handling performance.
In addition to the three conventional shock absorbers mentioned above, many deep-retrofit enthusiasts who have stringent requirements on vehicle performance will choose a bottle-mounted shock absorber that can hold more oil and gas to modify their car.
Since the pounds of traditional spring suspensions have been set at the factory, and metal fatigue occurs after a long period of time or intense work, the use of hanging bottles can be reduced at any time by increasing or decreasing the oil/gas. The shock preload is adjusted.
At the same time, more damping medium and longer damping piston stroke can also provide a more stable working environment. Therefore, hanging bottle shock absorption is quite common in many performance cars.
