6.1.3.f Signs of differences in suspensions
So, let's summarize.
Suspensions can be distinguished according to the following features:
- design: dependent, independent;
- the number and arrangement of levers: single-lever, double-lever, multi-link, with transverse, longitudinal or oblique arrangement of levers;
- the type of damping element: with telescopic or lever shock absorber;
- the type of springing element: carriage spring, spring, torsion bar, pneumatic, and hydro-pneumatic.
In addition to all of the above, it should be mentioned that suspensions are also distinguished by controllability, that is, by the degree of controllability of the state of the suspension: active, semi-active and passive.
Note
Active suspensions include suspensions in which the stiffness of shock absorbers, ground clearance, stiffness of the stabilizer bar can be adjusted. The control of such a suspension can be either fully automatic or with the possibility of manual control. Semi-active - these are suspensions, the control possibilities of which are limited to adjusting the ground clearance height. Passive (inactive) are regular suspensions that perform their role in their pure form.
It is also worth mentioning suspensions with electronically controlled shock absorbers, that are able to change their stiffness depending on road conditions. These shock absorbers are filled not with ordinary, but with a special liquid, which, under the influence of an electric field, can change its viscosity. If you simplify the principle of operation, you get the following: when there is no current, the car very gently drives over all the irregularities. But once the current is applied over the irregularities, it will not be very pleasant to drive. It will become very pleasant to drive the car on highways and in turns.
