[YesAuto Model PK] In this article, we will show you the rear suspensions of commercially available mid-size cars one by one. Unlike compact cars, mid-sized cars have higher positioning and higher prices, so the rear suspension is more commonly used with multi-links. Of course, this is not absolute, and even with the same structure, there may still be differences in the materials used.

Unlike compact cars, mid-sized cars have higher positioning and higher prices, so the rear suspension is more commonly used with multi-links. Of course, this is not absolute, and even with the same structure, there may still be differences in the materials used.

● Magotan

Magotan adopts a front Macpherson rear multi-link suspension system. From the pictures of the rear suspension, it can be seen that the structure of the multi-link is almost exactly the same as that of the Sagitar. The same thick lower swing arm, spring and shock absorption are separated in design. Multi-link independent rear suspension is more commonly used in mid-size cars. FAW-Volkswagen's suspension tuning of Magotan is relatively neutral, and it is in a balanced position between handling and comfort.

The structure of the front suspension McPherson is very common for front-drive models, and is suitable for various models of different levels. If you pay attention to handling, MacPherson is not a good choice, maybe double wishbone or double wishbone is more suitable.

Skoda Haorui

Rear suspension type: four-link independent suspension

Haorui and FAW-Volkswagen’s Magotan are Volkswagen’s PQ46 platform, so the rear suspension is the same as the Magotan’s four-link structure. The sturdy lower arm not only can withstand a lot of force, but also protects the other parts of the suspension well. The chassis is not injured when it is hit.

However, according to colleagues who have driven Haorui, its suspension is obviously much softer than that of Magotan, and it emphasizes comfort. Therefore, we judge that Haorui’s damping spring and Magotan may be different, but it is difficult to tell from the picture. This difference. However, it is obvious that Haorui has not shrunk compared to Magotan.


● Leading

Lingyu's suspension system design is relatively rare in the mid-size car class. The front is a multi-link independent suspension, while the rear is a trailing arm torsion beam type semi-independent suspension. This is completely contrary to the simple front suspension on most models and the complicated rear suspension. Its advantages and disadvantages are also obvious. The front multi-link suspension makes the car more stable when starting or braking, while the torsion beam type rear suspension itself has a simple structure and takes up less space. I believe that no one will have any impact on the rear space of the leader. Doubt, as for maneuverability, there is no need to pursue it too much.

● New Regal

The new Regal has been popular since it was launched, and you can often see its red figure on the street. In addition to the attractiveness of the new appearance, the body structure of the new Regal from Epsilon II also uses a lot of new designs. From the picture, we can see that the new Regal multi-link rear suspension has the same thick lower arm and uses cast aluminum alloy material, which can enhance structural rigidity and improve response speed while achieving lightweight.

Buick LaCrosse

Rear wheel suspension type: multi-link independent suspension

The new LaCrosse was launched at a low price that we did not expect, which really brought us a big surprise. In terms of suspension, the new LaCrosse is already a leader among medium-sized cars, and the new LaCrosse is a higher grade of the same level than it. , The same platform models, naturally will not disappoint us.

Although the platform is the same as the new Regal, the new Regal uses a more advanced shock absorption system, including the so-called CDC active hydraulic shock absorption system, which can adjust the softness and hardness of the shock 100 times per second, and the enhanced H-arm We haven't seen the high-level suspension. His lower arm uses the same aluminum parts as the new Regal, which is strong, fast in response, and light in weight.


● Winning

The name of the winning rear suspension provided by Changan Ford is “Composite Link Independent Suspension”, which actually means multi-link. The winning front and rear suspension is what we call the most common medium-sized car suspension-the front McPherson rear multi-link. The winning suspension tuning is obviously biased towards sportiness and is very tough, so that it will cause a certain discomfort to ride for a long time.

MG MG 7

MG 7 is a model with an original British style. The name of the rear suspension in the official information is: “Innovative Z-shaped longitudinal swing arm and double wishbone rear independent suspension”. This name seems to be a bit “flicker.” How can the feeling of “innovation” be regarded as “ingenuity”?

After seeing its rear suspension, it is indeed different from the general double wishbone and multi-link suspension. Its spring and suspension oil have their respective fulcrums, and they are not connected to the lower swing arm, plus good tuning , Which makes the MG 7 achieve a better balance between handling and comfort, but the so-called “ingenuity” is still a bit too much, right? After all, this is not a new car.

● Accord

Because the Accord uses a sub-frame structure, the design of the connecting rod is more flexible. At the same time, because the sub-frame bears most of the impact force and acts as a buffer, there is no need for a sturdy swing arm like the Magotan. However, it still looks a little slender. Theoretically speaking, the design of installing the suspension on the sub-frame is very clever. Installation and maintenance are simpler and more convenient. It also enhances the rigidity of the car body. It can not affect the geometrical changes of the car body too much during driving.

In fact, the front and rear suspension system of the Accord is similar to that of the Mazda 6. Both the front suspension is a double wishbone and the rear suspension is a multi-link. However, the overall performance of the Accord is biased towards comfort, but if the existing multiple “joint” connections are replaced with rigid ones, its handling response may be greatly improved.


● Camry

When it comes to suspension, the Camry may be a little shy. Because, among the models listed today, let alone how well the suspension is tuned, the Camry is the weakest in terms of structural form alone. The dual-link independent rear suspension is easily misunderstood as a multi-link form in the name, but in fact this structure is based on the improvement of McPherson, and it should be called “link strut” suspension to be precise. .

In addition to the relatively simple structure, it can be seen from the picture that the connecting rod is not strong enough. The strength and rigidity of the suspension system that bears the important connection between the body and the wheel is a bit worrying.


● Nature

When it comes to comfort, Teana can almost be said to be the top pick among mid-sized cars at the same price, and the design of the seat is indispensable here, and of course the suspension system cannot be ignored. The spring bracket on the lower swing arm of the multi-link rear suspension is very large, and it can be seen that the alloy material is used.


● Mazda 6 Ruiyi

The Mazda 6 Ruiyi and the old Mazda 6 use the same front double wishbone rear multi-link rear suspension. This front-to-rear collocation model is obviously manoeuvrable, and the Mazda 6 has always been well-known for its maneuverability. The precision of the steering and the suppression of the head-up phenomenon when starting acceleration are directly related to the adjustment of the front suspension of the double wishbone. Rear multi-link rear suspension is very common in medium-sized cars, but still the same sentence, the structural principle is similar, but the specific adjustments are different from each other.

● BYD F6

Just looking at the picture of BYD F6, it is easy to confuse it with the previous Accord. Indeed, from the structural point of view, the BYD F6 is exactly the same as the Accord, with the front double wishbone and the rear multi-link. Putting aside the difference in tuning techniques, let's just say that the distribution of the connecting rods is almost exactly the same. And the structure of the subframe is also used.

In terms of the price of BYD F6, even if you refer to a well-known model, it is commendable for courage and kindness to be able to adopt such a suspension structure. After all, it is easy to imitate the appearance, but at least the corresponding cost is required to imitate the structure, especially for this relatively complicated suspension system, which requires both cost and level.


● Junjie

It is also a medium-sized car of its own brand. Junjie also uses a multi-link independent rear suspension with anti-roll bars. The real thing is not its rear suspension, but the independent front suspension of the front double wishbone. Although there is no picture, I still have to say a few more words here. The double wishbone is used as a front suspension on some high-end models. The handling is much higher than that of McPherson, and the space is less than that of multi-links. .

Chevrolet Epica

The Chevrolet Epica uses a multi-link suspension, which looks similar to the Accord and BYD F6, and this is the multi-link structure commonly used in Korean cars. The dynamic performance of Jingcheng also has the common characteristics of Korean cars, that is, the suspension is soft and comfortable, while the performance in terms of handling is very general.

Mingyu

Mingyu is actually the old Sonata with a modified appearance, so it is not surprising that the chassis is exactly the same as the Sonata. It seems that its suspension is not very advanced, and thinner springs may not be able to effectively support the body when cornering at high speeds. After all, this car is still based on daily driving practicality and comfort, so there is nothing wrong with this setting.

● Audi A4L

Among the mid-size cars that came out this time, the Audi A4 is the identity of a high-end car. This can be reflected in both the brand and the price. Today, the most important thing that can reflect its high-end identity is its suspension. The front multi-link and the rear trapezoidal link, in fact, can hardly see its form from the picture. Because the chassis guard is very tightly wrapped, except that the swing arms on both sides can be seen to be made of aluminum alloy, the other parts are almost covered.

However, the chassis of high-end cars is obviously more classy, except that the guard plate almost protects the entire chassis, and you can't see the messy pipelines and component connections.

ES350

Is the Lexus ES350 priced at around 500,000 yuan or a medium-sized car? That's right, because he uses the same platform as the Camry, so although his price exceeds many medium and large cars, we can only classify it as a medium-sized car. So the suspension of the ES350 will not be the same as that of the Camry, right? You know that Camry is arguably the worst among medium-sized cars, and the ES350 is twice as expensive. If you think so, the ES350 will disappoint you.

Visually, there is no difference between the ES350's rear wheel suspension and Camry's. Could it be that the ES350 uses higher-strength materials? I don't know, I hope so, and I hope it can make up for the inherent shortcomings of the double link.

Pentium B70

We all know that the Pentium B70 is a model on the same platform as the Mazda 6, but with a “vest”, but the price is lowered a lot, so it is more cost-effective. So will you cut corners where you can't see it? At least not on the rear suspension.

The Pentium uses a multi-link independent rear suspension. Although not much is exposed, at least the lower arm is very thick in the visible range, so we can rest assured of this car. Similarly, in addition to the Mazda 6, there is a Pentium B50.

BMW 3 Series

For the BMW 3 Series that is known for its handling, the rear suspension will naturally not disappoint us, but because this car is dirty and the shooting angle can't show all of its suspension, we can only take a look at it.

It is not uncommon for medium-sized cars to use multi-link rear suspension, but there are not many that use aluminum alloy materials. At present, the mainstream is the new Regal, Magotan, Teana, A4L and 3 series, while the previous cars are all The front wheels are activated, and the 3 Series is rear-wheel drive, so no matter what, no one can deny its excellent handling performance.

Reiz

Although the sales of Reiz are average, no matter from which point of view it is considered, the Camry just sells so much better than it because it looks more generous and has a larger space. It is really unreasonable. One is front drive + dual link, the other is rear drive + multi link, the other is L4, and the other is V6. The grade is different.

Although it is difficult to observe the full picture of the Reiz rear wheel suspension, we can still see that the part connected with the wheel is made of aluminum alloy, the sub-frame is strictly protected, and the lower swing arm is also very strong. Moreover, it is still a rear-wheel drive plus V6. It can only be said that the person who buys Reiz does not value space and appearance very much, but people who know the car very well.

Sibo Rui

Sperui is actually the Honda Accord, so its suspension structure is no different from that of the 8th generation Accord. This suspension system has a good potential. As long as it is properly tuned, it can get excellent handling. As a sports model, its suspension feels a bit tougher than that of the Accord, but it is not so radical in relative terms, and it still takes care of a certain degree of comfort.


Summary of medium-sized car articles:

From a comprehensive point of view, the structure of the front suspension of the medium-sized car is different, including MacPherson, double wishbone, double wishbone and even multi-link. However, even the Accord and Ruiyi, which have very similar front and rear suspension, have very different handling performances. Therefore, the suspension itself is a relatively complex structure. In addition to ensuring the basic strength and rigidity, it also requires a high level of training ability.
