How much do you know about chassis suspension? What is the difference between a torsion beam and a multi-link?

Suspension is a familiar and mysterious component in the car. Many car owners may not have a comprehensive understanding of some details. If a professional explanation is used, it may be very boring, so today we will come to you. A simple introduction to some of the chassis suspension. Chief among them is the difference between a torsion beam and a multi-link.

First, the classification and characteristics of hanging

Suspension is generally divided into two categories, one is an independent suspension in which the two wheels work separately and do not interfere with each other, and multi-link is an independent suspension; the other is a direct connection between the two wheels. Dependent suspension, and torsion beams belong to the category of dependent suspension.

We know that the feature of multi-link suspension is that each wheel operates independently, and the wheels on one side will bear the potholes by themselves, and will not be transmitted to the other side of the car, which ensures that the inside of the car is in a certain sense. The comfort of the occupants, but this process is more complicated and takes up space, and the handling will be weaker, of course, the price is also high;

The characteristics of torsion beam suspension are that it has a simple structure, does not take up space, and has strong maneuverability, and most importantly, low cost, so it is also used in a wide range of models.

Second, the advantages and disadvantages of torsion beam and multi-link

So, is the torsion beam suspension with low cost and small space really bad? And the multi-link independent suspension must be very good and "independent"? In fact, each suspension has its own It should be combined with the use of specific models, equipped with corresponding suspension, and the final solution can be provided by maximizing strengths and avoiding weaknesses.

For example, some vehicles that emphasize control will use torsion beam suspension, such as Honda's signature models Civic Type-R and Golf 7, etc. If independent suspension is used, although it is comfortable, it will affect the integrity of the body, that is, we often If you want to be comfortable, don't control it, and if you want to control it, don't think about comfort.

So is independent suspension necessarily independent? If the requirements are strictly distinguished, some multi-links are not pure independent suspension. Because the premise of independent suspension is that the two wheels operate independently and do not interfere with each other, but on some models, in order to prevent the lateral displacement of the wheels under independent suspension, a lateral stabilizer bar is added between the two wheels. With such a Connection, then naturally it can not be regarded as independent suspension.
