Nowadays, when consumers buy cars, they also start to pay attention to the chassis suspension, such as whether it is independent or not, and whether the suspension is hard or not. Many people think that the suspension must be soft, especially for SUVs, so that they can sit comfortably. But is this really the case? Today we will talk about those designs that affect the comfort of vehicles.
■ What is the current mainstream chassis structure for urban SUVs?
McPherson + multi-link is the most common
What’s the matter with the suspension soft and hard?
First of all, we have to interpret what is going on with the “soft” and “hard” suspensions experienced by everyone. This involves a pair of partners on the chassis-springs and shock absorbers, and their “character” also determines The main characteristics of the suspension.
If good comfort is to be achieved, it must have such properties:
It has toughness, moderate spring compression, large shock absorber damping and good absorption effect. The overall performance of the suspension of this type of vehicle is better.
When it comes to cost, it is true that economical SUVs are not easy to achieve balanced adjustments, but we still found a counterexample – Boyue, one of the best-selling SUVs in the 150,000 class, uses a front MacPherson and a rear multi-link At the same time, a lot of effort has been put into the adjustment of the suspension form. The thickness, response and sound insulation of the chassis are all outstanding in the same class of models.
Soft suspension ≠ good comfort, toughness is king
The key to suspension comfort is energy absorption
The suspension itself needs to absorb all kinds of jumps and vibrations brought by the road surface. If it cannot absorb energy well, resulting in continuous bouncing, how can people sitting in the car bear it… It’s like a very soft mattress. It is also very tiring.
■ From the inside to the outside, what other chassis-related designs affect comfort?
The details of seats, shock absorbers, and tires cannot be ignored
A. Seat vibration is small, long-distance without fatigue
B. The introduction of LVC valve into the shock absorber has balanced performance
In addition, the car body also has a problem of resonance frequency. It is necessary to find a suitable resonance point and avoid the area where the human body feels bad, so as to ensure the comfort of the occupants when the vehicle is driving on a bad road.
C. The rubber sleeve on the chassis should be strong enough to absorb vibration
D. The tire pattern is reasonable and the noise is small
Conclusion: Suspension and comfort once again prove that the word “balance” is the main starting point of a good car (especially a family car)-of course, this is easy to say but not easy to do well. The vivid example of Boyue’s chassis skills well explains the characteristics of balance. Remember, the softer the chassis, the more comfortable it is.
