At present, when we buy a car, many people attribute the performance and comfort of the vehicle to the structure of the suspension. The general psychology is that the independent suspension is more comfortable and better than the non-independent suspension. But is this really the case?
Suspension is a vital structure of the entire vehicle, and its performance determines the texture of the entire vehicle, so a good and truly suitable suspension is the most in line with the balance of the vehicle.
What are the structural components of the suspension?
Suspension is the general term for all the force-transmitting connection devices between the frame of the car and the axle or wheels. The main function of the suspension is to transmit all the forces and moments acting between the wheels and the body, such as supporting force, braking force and Driving force, etc. The main structure is spring and shock absorber.
What suspensions are there currently?
In simple terms, it is divided into two types: independent suspension and torsion beam non-independent suspension. If further subdivided, independent s

What suspensions are there currently?
In simple terms, it is divided into two types: independent suspension and torsion beam non-independent suspension. If further subdivided, independent suspension will be divided into single trailing arm type, multi-link type, and cross arm type. , Candelabra, MacPherson, etc., for the sake of simplicity and understanding, I will classify them as independent suspensions.
Independent suspension
The so-called independent suspension means that each wheel is individually connected to the frame or body through the suspension. The fluctuation of one vehicle type will not affect the dynamics of the other wheels. Relatively speaking, the advantage is that the wheels do not disturb each other. The potholes will affect the entire vehicle and greatly increase the ground adhesion of a single wheel. And it is a disconnected axle, which makes the vehicle height lower.
Torsion beam non-independent rear suspension
The torsion beam-type non-independent rear suspension is the first suspension mode we have come into contact with. Earlier we called the plate suspension is this kind of suspension. In simple terms, the rear two wheels are connected to a rear axle, and the wheel on one side has Fluctuations, the other side will also be affected, which will cause the entire rear of the car to fluctuate. The structure is simple, the cost is low, easy to repair, the wheel angle is small, the degree of wear is small, and the space is small. Some cheap cars.
Independent suspension must be better than non-independent suspension?
When consumers buy a car, most of them still see the potential rigid condition of independent suspension, thinking that this is a must in the big car anyway, but the quality of the suspension is not determined by this so-called structure. It is the balance of the suspension relative to the vehicle. Different suspensions have different advantages and disadvantages on different cars.
So how do you treat the right suspension when buying a car?
What kind of suspension
Manufacturers have many ways to determine the choice of suspension, which will be determined from factors such as cost, comfort, and model positioning. For example, Jinke, ENCINO, Yibo, small SUVs and some family cars, in order to save space and cost, most of them will use The torsion beam is not independent of the rear suspension. Some luxury cars will use multi-link independent suspension to ensure comfort, and for many performance cars, in order to pursue better tracking and handling, they often use more complex independent suspensions for tuning. Still have to choose the suspension according to the model and needs.
The manufacturer's ability to adjust the chassis
If you have confidence, a little stone can become gold. When everyone is pursuing consumer demand and replacing them with independent suspensions, the French chassis masters are still using torsion beam non-independent suspensions, such as Citroen Tianyi C5, matched with the PHC hydraulic shock absorption system, after actual driving Later, you will know that the original torsion beam can also be more comfortable than most independent suspensions, because compared to many cars equipped with independent rear suspensions, its shock filtering texture, comfort and stability are very high, and the current Peugeot is almost completely The system is almost all torsion beam non-independent suspension, so the manufacturer's chassis power is also one of the criteria for judging the quality of the suspension.
Summarize:
According to common sense, the hard and deterministic answer is that independent suspension must have better stability for some potholes than torsion beam non-independent suspension, with a low center of gravity and a high adjustable limit. But whether it is really good or not depends on the suspension tuning mentioned above. Therefore, the suspension should not be complicated in structure, it should be judged comprehensively from many factors.
