The shock absorbers are composed of compression springs that allow us to correct the attitude, movements and braking behavior of a vehicle.
The spring is a fundamental part of the suspension that allows you to manage and correct the weight.
A spring is identified with a constant that indicates the force with which it responds to a crush.
According to our experience in the field of set-ups and shock absorbers and checks, we know that for example on a motorcycle, the spring is preloaded i.e. flattened by a few millimeters from the maximum extension, in this way it therefore exerts a certain thrust even when the motorcycle is stationary.
Acting on the preload consequently changes the force it exerts in supporting the vehicle.
The springs are distinguished by the load index (k) and are of two types:
- With a linear response, that is, they have turns with a constant pitch, they respond with a force directly proportional to crushing.
- Progressive are the most common and consist of two sets of turns, one with a narrower pitch and the other with a wider pitch. Initially the first ones are crushed, ensuring a softer response; when they are all in contact the second ones begin to work.
In this case the spring is that detail that increases comfort
