How much do you know about chassis suspension? Is there a big difference between a torsion beam and a multi-link?

Suspension is a familiar and mysterious component of the car, in some details may not be a lot of owners do not necessarily understand very comprehensive, if you use a professional explanation may seem very boring, then today we will introduce you to some of the chassis suspension of those things. The main one is the difference between a torsion beam and a multi-link.

First, the classification and characteristics of the suspension

The suspension is roughly divided into two categories, one is the independent suspension that the two wheels work separately and do not interfere with each other, and the multi-link belongs to the independent suspension; The other type is the non-independent suspension that directly connects the two wheels, while the torsion beam belongs to the category of non-independent suspension.

We know that the characteristics of multi-link suspension are 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 the comfort of the occupants in the car in a certain sense, but this process is more complex and takes up space, and the handling will be weaker, of course, the price is also high;

The torsion beam suspension is characterized by simple structure, does not take up space, and has strong handling, and importantly, low cost, so it is also used in a wide range of models.

Second, the pros and cons of torsion beams and multi-link

So, is the low-cost, small-space torsion beam suspension really bad? And is the multi-link independent suspension necessarily good and "independent"? In fact, each suspension has its own characteristics, and it should be combined with the specific vehicle type and equipped with the corresponding suspension to provide the final solution.

For example, some vehicles that emphasize handling will use torsion beam suspension, such as Honda's signature model 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 say that if you want to be comfortable, don't control, and don't think about comfort if you want to control.

So does independent suspension have to be independent? If you make a strict distinction according to the requirements, some multi-links are not purely independent suspensions. 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 offset of the wheels under the independent suspension, a lateral stabilizer bar is added between the two wheels, and with such a connection, it is naturally not an independent suspension.
