Using suspension black technology, one design solves the contradiction between comfort and exercise!

When it comes to chassis, do you know that Honda also has its special technology in suspension? This technology is called AmplitudeReactiveDampers,Damper, that is, damper. From this name, we can see that this technology is used in shock absorber. What kind of technology is this?

The first thing to talk about is the shock absorber, which, as its name implies, is a part used to absorb the vibration from the road surface. It is a part composed of a spring and a damper, that is, a shock absorber. The shock absorber has damping oil and a piston, which connects the swing arm and the frame through a connecting rod. When the vibration comes, the spring will first over-compress to absorb these vibrations, but the spring compression will then rebound, if it is not limited, then the spring will break compression and springback, and because the spring is also connected to the frame and the swing arm, this will cause the whole car to jump up and down, and this jump will make the car out of control. In order to avoid this situation, avoiding the machine needs to apply resistance to the spring, resistance to its constant jump. And this is the basic working principle of the dodge. In addition, because the shock absorber is connected to the frame and the swing arm, the shock absorber also supports the vehicle.

I believe that many car owners’ definition of comfort is that the shock absorber is very soft, after all, the shock absorber can absorb the shock, so that the bumps on the road will not be stored in the car. But do you know? Weak shock absorbers are likely to cause the vehicle to get out of control. Why? Because the vehicle is driving in the bend, the vehicle will roll and the center of gravity will shift, and the heart will follow and shift to the wheel of the outer bend. At this time, if the degree of gravity transfer is too much, and the shock absorber is soft, in the heart transfer process, it will be difficult to withstand this sudden amount, at this time, the vehicle is very tolerant of boat display, this phenomenon will be intensified, it will be easy to make the vehicle out of control. Therefore, shock absorbers can not be soft, but the problem is again, not too soft words will affect comfort, so comfort and manipulation are opposite?

The picture above is actually a display of the shock absorber filled with high-pressure gas, but you can also see how the shock absorber works. In fact, in addition to the gas that can make the shock absorber move faster, the size of the piston hole valve can also control the speed of its movement. however, if the speed is controlled by the piston hole valve, it will directly affect the shock absorber software and hardware.

What is the structure of the shock absorber with two pistons? it probably looks like the picture above, but of course it will be much more complicated than this.

This is how AmplitudeReactiveDampers works. You can see that the shock absorber has two pistons. Because of the different hole valves, the speed of the piston is also different, and it is this different speed that enables it to absorb vibration quickly and provide support at the same time.

It’s actually a shock absorber with two pistons. What’s so special about it? Generally speaking, a shock absorber has only one piston, which has a small hole valve, and the shock absorber is filled with damping oil with high viscosity. When the shock absorber is about to move, because the liquid cannot be compressed, so the damping oil can only flow through the piston through the piston hole valve, but by the damping viscosity, and the piston hole valve, so it will form resistance, prevent the piston from moving, in theory. As long as the piston hole valve is small enough, the piston will move more, and such resistance can form resistance to compression or resilience, thus forming a support. However, the result is that the resistance is so high that the spring cannot compress and cannot absorb the shock. This is what we call shock absorber. And avoid soft, it is phase, piston hole valve is larger, so that the damping can flow quickly to the piston, so that the spring movement can better absorb vibration. In fact, it can be reflected in the design of the shock absorber.

In fact, there is nothing wrong with saying that comfort and manipulation are opposing, but Honda has found a way to balance it through technology, and AmplitudeReactiveDampers is such technology.

However, the reason why AmplitudeReactiveDampers can balance the two states is that it has two pistons, one of which has a larger hole valve and the other has a smaller hole valve. when the vehicle is driving on a potholed road, the piston with larger hole valve can first give the spring a fixed space to absorb bumps and movement. when the vehicle needs support when it comes to the bend, the smaller piston with the hole valve can stop the spring from moving and provide support for the vehicle. And this design can better balance fitness and control. Of course, it is certainly simple to say, but the production requires the support of data, such as how to control the vibration frequency, how to control the vibration frequency, and so on. In fact, more of these data come from the field, which is the reason for the test ground.
