Kia Sid.Rear suspension
The rear suspension is independent, multi-link (three transverse and one trailing arm on each side), with telescopic shock absorber struts 4 (Fig. 7.3) and 13, stabilizer 9 for lateral stability. Guide elements rear suspension trailing arms 7 and 16 are control arms and transverse arms 1, 15.2 and 10. Such a system of arms in combination with elastic rubber-metal hinges provides the suspension with the property of "passive steering": when cornering rear wheels turn a small angle in the direction of the turn, which provides better stability and control of the vehicle.

The use of a multi-link type of suspension system has already become a classic in building the rear of the chassis. modern cars... The choice was not random. At the heart of the construction of the rear kia pendants Sid uses the idea of \u200b\u200bfixing the wheel hub using several levers at once. The result of finding them in different planes relative to the body is the ability to make more precise settings for the suspension system.
The multi-link system is based on:
- levers located in two planes of the car;
- stretcher;
- coil springs;
- hub supports;
- shock absorbers.
Purpose of suspension elements
In the scheme for constructing the rear suspension of the Kia Sid, the engineers decided to use four levers to mount the wheel hub, three of which they installed in the transverse (relative to the car body) plane, and the fourth in the longitudinal one. Acting as guiding elements, levers are capable of solving other problems. For example, be responsible for the position of the wheel at the moment of movement in relation to the body.
All parts of the harness can be connected using a bolt connection, ball joint or elastic element. At Kia Sid, elastic elements - silent blocks are used to attach the rear suspension components to each other. It should be emphasized that they can only be replaced but not repaired. Elastic elements, connecting the suspension system with the body through a subframe, are designed to reduce vibration during movement. In addition, silent blocks can reduce the noise level of the suspension.
The stabilizer struts absorb and absorb most of the lateral vibrations arising from surface movement problems. Their service life depends on the intensity of trips on a particular car and the state of the roads. It is recommended to change racks after 60-80 thousand run.
Trunnion ( rounded fist), perceiving the forces coming from the wheel, redistributes them between other parts of the suspension. Sometimes novice owners confuse a steering knuckle with a wheel hub. As a result, misunderstandings arise and it can be difficult to help with repairs. What is the trunnion and where the location in the design will help to understand the photo of the rear suspension of the Kia Sid. As you can see in the photo, the hub and trunnion (circled in the diagram) have different locations.
Comparison of rear suspension across generations
Rear suspension previous generation there were many complaints. Mostly car owners complained about its extreme rigidity. According to them, when driving on freshly laid asphalt, it worked like a clock. But when driving on the most common roads in Russia and requiring repair, even the smallest potholes were felt. As a result, the Korean automaker, taking into account the wishes, changed the settings to softer ones. Now what can we expect from the rear suspension of the new generation of this car?
Let's run a test. And so, we sit behind the wheel and go. Here we notice some minor damage to the road ahead. We concentrate, thinking how much it will shake. And we often feel nothing. Here in front of us appeared the cover of the sewer manhole. Of course, it is better to go around, but we are conducting a test. Let's go straight. Yes, the feeling of moving is pretty strong. As a result, after careful consideration of everything we have experienced, we come to the conclusion that the suspension system of the new generation car has noticeably improved the previous one. Nevertheless, I would like to wish Kia to modify the suspension for Russian roads.

New player on a golf class: Kia Ceed.
Representatives of "Kia" say: with the advent of "cee'd" begins new chapter in the history of the company - from now on, cars of this brand must compete on equal terms with European models. Yes, that's such a bold application! The main rivals of the debutant are marketers "Kia" 
see " Ford focus"and" Volkswagen Golf"The bar is set high. Will the Koreans be able to outplay the market legislators? To find out, we went to Italy for our first acquaintance with the Kia cee'd."
The STRANGE word "cee'd" (read as "siid") is formed by a combination of the letter "C" meaning "segment C" (golf class), and the abbreviation "ED" - "European Design". Everything else, including the unusual spelling with a lowercase letter and apostrophe, is added for beauty. Koreans believe that such a name will fondle the European ear and be easy to remember. It's really easy to remember. Personally, I associate it with a bearded anecdote: "Do Muscovites call yak? - Beer!"
However, jokes aside. Here they are, the new Korean contenders for the European bestseller title, lined up in the parking lot outside the Rome airport ...
Which car do you want? Gasoline or Diesel? With "mechanics" or with "automatic"? - asked the girl giving the keys to test cars... - We have three petrol and one (so far one, sorry) diesel to choose from.
Good start. European buyers are accustomed to choosing from a wide range of motors and running their fingers over a long list of standard trim levels.
It seems that the organizers found out in advance that Russians do not favor weaker motors, and more powerful ones on our market are too expensive. At least for golf class cars.
Keys in hand, I head towards the line of cars. All are five-door hatchbacks. There are no other bodies yet. Towards the end of 2007 a station wagon will appear, followed by a sports three-door. There will be no sedan at all. After all, this class already has " Kia cerato"sedan." It sells well, and so far there is no need to create a replacement for it.
Everything at once
The new "Kia" LOOKS very good. The look was developed in the new Kia design center in Germany - joint efforts of German and Korean specialists (who, in turn, learned from Italians). The result looks a bit like a hatchback. " Toyota Corolla", but still - great. About the faceless design, for which they criticized for many years korean carsseems to be forgotten now. "Cee'd" looks stylish and modern.
The interior is spacious, the seat adjustments are even redundant: having moved all the way back, I cannot reach the pedals. I immediately noticed the front panel trim. This is not the slippery and sonorous plastic that is familiar to old Korean models, but an elastic material, 
reminiscent of rubberized fabric with fine textured notches. It's nice to touch it or just hold it with your palm. Somewhat spoils the impression of the lurid frame of the center console "like aluminum", but this is my personal opinion. Someone may not agree with him. The build quality and fit of the elements - do not find fault.
And the level of equipment is even higher than that of some competitors. The car has everything. What all"? It's easier to say what isn't there than to list a long list of installed options. I got a car in the richest TX configuration (there is also an initial LX and an intermediate EX). For complete happiness, it lacks only a color LCD multifunction information display... The display, however, is, but small and monochrome. The navigation system map cannot be displayed on it. Shows only the direction of movement in the form of arrows.
But rich equipment is not the most important thing in a car. Safety was a priority in the design. Kia engineers claim that in the end they managed to create one of the most safe cars in class, and the upcoming official Euro-NCAP crash tests will confirm this. I don’t know, wait and see. There are at least six airbags in the car. And even in the cheapest LX configuration. In addition to pillows "cee'd" can even be equipped eSP system... But it is installed only on the richest TX versions.
With extraordinary ease ...
REMOVING, I shamefully "stalled". Just like a newbie from a driving school. The reason for this is the low thrust of the 1.6-liter engine at low revs (as it actually should be) and the too light, almost weightless clutch pedal. It's very difficult to catch the moment of switching on from habit. However, in city traffic, when you have to constantly change gears, such ease is more a blessing than a disadvantage: the leg does not get tired.
According to the first sensations "Kia cee'd" - the car is more female (if, of course, it is appropriate to subdivide cars by gender). All efforts are small: on the pedals, on the steering wheel, on 
gearshift lever. The stronger half of humanity usually prefers tighter and more informative controls.
The car accelerates very willingly. For dynamic city driving - just what you need. And on a suburban highway, if there are no speed limits, without much stress, you can drive the speedometer needle beyond the 200 km / h mark. I suspect that with a more powerful 2-liter engine "Kia cee'd" will be able to please even the experienced driver. But, as always, there is a fly in the ointment - the suspension is too soft. Even the average European housewives prefer it harder. In this case, one has only to turn off the expressway onto a secondary road that does not differ in the special quality of asphalt, as the suspension begins to "break through" on more or less serious bumps and irregularities. You have to slow down and drive more carefully. But even on the cobbled pavement (there are many such streets in Italian towns) there is silence in the car - nothing creaks, rattles or clanks. A rigid body, good finishing materials and high-quality assembly are the key to acoustic comfort.
After a few kilometers, the country road smoothly turned into a winding mountain serpentine. All of Southern Europe travels on such roads. Apparently, therefore, it was important for the organizers of the test drive to demonstrate how the car behaves in such conditions. On a serpentine road, I caught up with an old "Alpha", driven by a local resident who seemed to know all the turns by heart - he stormed them very fearlessly. I caught up with something, but it was not possible to get around it. Seeing that I was "hanging on the tail", the Italian drove for real - "delivering" the car to slide at the entrance to the turns. Frankly, I got scared, and I chose to lag behind. That would be a stiffer suspension and a steering wheel more informative ...
Nevertheless, it must be admitted that the Koreans did very nice car... Even by high European standards. " Alfa romeo", of course, it did not work out (and such a task most likely did not stand), but" Fiat "or something very similar in sensations - quite.
In external appearance "Kia cee'd" reads quotes from the design of many popular hatchbacks. Nevertheless, it is quite distinctive.
There is no answer to this question yet. In an official press conference, the head of Europe for Kia Motors said prices "will be very competitive." At the same time, he noted that Kia is striving to move away from the established image of a "manufacturer of cheap cars". That's it, not a word more. What this means is anyone's guess.
Shy guy.
Behind the rather modest design of the new Kia Cee’d, there is an amazing car, because it surprised everyone who tested it. When I went to pick up the car, I thought: "Well, Kia, well, he's going, inexpensive, modest, most likely boring," but it turned out ... It turned out the following ...
The design of the car is deliberately simple and discreet. Numerous complex lines of the car help to make such a conclusion: the hood, the bottom of the doors, the headlights and rear lights... In general, there is a slight similarity with the Japanese sister - Toyota Auris, but more with previous version Toyota Corolla hatchback.
Inside, you will not find any ultra-fashionable and innovative design solutions either - everything is familiar, popular and therefore convenient. Everything was done with acceptable quality and a good fit of parts to each other. The plastic used is not the best (especially on the door handrails), but it does not rattle and does not buzz at speed, or on bumps, or with loud music. Its texture is a light imitation of fabric and it is more or less pleasant to the touch. Use plastic engineers a little worse quality, and the salon would become simply unacceptable, and as they say - bearable.
The center console is slightly noticeably turned towards the driver - this is more convenient, and the glove compartment opens very low at the passenger's feet - on the contrary, it is not very pleasant: in order to rummage in the glove compartment, you need to ask the person sitting next to first tuck his legs. It's not the first time to meet such a defect in cars. The devices are well readable, everything is clear and there are no "proprietary" features of the control of certain functions - a classic. No, though! For a very long time I wondered how to change "Fahrenheit" to "Celsius" on the monitor showing the temperature overboard. By the way, the instruments (tachometer and speedometer) are made in a semi-sporty style (the speedometer is placed in a half-glass), which, at first, caused a smile (about how it disappeared - a little later). I liked the "correct" height of the central armrest - flush with the armrests on the doors, but did not like the fact that there is simply nowhere to put a bottle of water in the cabin - there is only one cup holder (for all!), And there is only enough room in the door niches for papers and rags, behind - the same picture, only there is no central armrest. But there is plenty of room for legs, knees, shoulders, and passengers' heads. But there were no complaints about the trunk at all - it was spacious, with a high hinged door and no hinges going inside, with a low loading opening and with a relatively flat floor, if the rear seats were folded down (there is a difference in height, but smooth, like most classmates).
While Kia Sid shows himself to be a sort of average peasant, a car without pretensions and manners. But it is worth leaving the parking lot and ...
… And the car starts to amaze, surprise, delight. From this moment, the opening begins. Nothing of the kind was expected from the car, and the fact that there is a car on the market with similar driving qualities for such a modest price is a real discovery and that's it. Kia Sid is perfectly controlled! Without any exaggeration or reservations. Believe it or not, but in terms of this quality it is comparable to the “Kopeyka” BMW and the 307th Peugeot (I myself would not believe it and laugh it, but the fact that can be easily verified by passing a test drive at a dealer remains a fact). I was both happy and depressed. On the one hand, it is good that the test was not boring, but the fact that two of my favorite cars in the "C" class had an inexpensive competitor (in terms of handling) plunged me into despondency. The car goes clearly in a straight line at a speed of 170 km / h, even if you let go of the steering wheel (there is a clear "zero" in the "straight" position - like a kind of hollow), Sid wanted to spit on the track, and he enters the turns so briskly, clearly, confidently and accurately that I wanted to do it over and over again. Rearrangement is not a problem: left and right and you fly calmly further - you did not risk it. Feedback with wheels is transparent and understandable - all information is on the steering wheel, which turns into a precise instrument. Now try to hit the brakes sharply - Sid stops smoothly and quickly, and most importantly - you don't need to catch him on the road - he doesn't wobble, doesn't skid if braking occurs
in the turn. It is pleasant and joyful to ride like this! At the same time, Sid was not shod in the most driver's rubber with a low profile and a hard side, and Michelin Energy 205/55 R16 is also worthy rubber and showed itself with good sidesbut there are better ones for the drive.
Special respect to the automatic box. Its work matches the character of the machine. Shifts occur quickly and almost imperceptibly, the machine responds quickly and correctly to any change in pressing the gas pedal, raising or lowering the gear: you go 80 km / h in fourth gear, you need to quickly pick up speed - press the gas harder, the machine immediately switches to third gear ( or the second - how to press) and accelerates the car as fast as its 1.6-liter, 122-horsepower engine is capable of (Sid will soon appear on the market and with a 2-liter engine of 143 hp, the body will also appear " wagon "- SW).
Multi-link design in a location such as the rear suspension kia car Sid is easy enough to meet today. This is a common scheme favored by the vast majority of manufacturers for the sake of improving stability and endowing their models with confident handling.
Such a suspension is possessed by the "hero" of our material - Kia Sid. This scheme is not simple, but allows the manufacturer to achieve very precise chassis tuning.
At the heart of any multi-link suspension design, of course, the front suspension is not taken into account here, the following elements are present:
- levers, some of which are transverse and others are longitudinal;
- one-piece stretcher;
- twisted spring elements;
- shock absorbers;
- hubs with trunnions;
- stabilizer with struts.
Suspension tasks
The layout of the rear chassis in the Kia Sid model includes 4 levers per side. Three elements are transverse, and the 4th is longitudinal. By means of the lever system, the correct holding of the hub together with the wheel in motion in a unit of time is ensured. The subframe reduces vibration transmitted to the body by the suspension elements.
Fastening of each of the levers is made using bolted connections through rubber-metal bushings, called silent blocks. Such cushioning components are present not only in the arms, but also in the attachment points of the subframe itself.
To damp vertical vibrations, shock absorbers are used, the work of which is supposed to work in tandem with springs. This ensures the most efficient position of the body in relation to the road surface. This is especially noticeable when driving over irregularities, when the body, which has tilted under its own weight, quickly and efficiently returns to its original place using the indicated shock-absorbing elements.
The stabilizer is responsible for cornering stability and resistance to lateral forces, which is attached to special brackets of the subframe and is connected to its struts at both ends. The resource of their (racks) is small, about 60-80 thousand km, since they perceive loads with increased effort. The durability of these components, as well as of other rear suspension assemblies, is influenced by the condition of the road surfaces and the intensity of travel.
The steering knuckle is a kind of link between the levers. With its help, the forces that arise in the suspension components when the KIA Ceed is moving are redistributed. A hub is installed in the trunnion itself (or fist), which serves to hold the wheel and ensure its rotation. Some inexperienced owners are spontaneously misled by confusing the trunnion with the hub. To help such a contingent, we will address a photo that will allow us to finally understand the type and purpose of these elements. The fist in this diagram has been circled to eliminate further confusion.
Differences between suspensions in different generations of LEDs
The rear suspension in the previous generation caused a lot of criticism due to its excessive rigidity. Kia owners Sid complained about the lack of comfort when driving bumps and potholes, when each bump is felt in full. The manufacturer listened to the angry owners and re-tuned the suspension, giving it a different characteristics in terms of balance between softness and stiffness, without affecting handling.
How has the suspension behavior changed in the new generation of the Kia Sid model? By the way, the front suspension has also been improved. Let's set up a test. Having started the movement, we focus on the sensations in anticipation of shaking when passing through irregularities. However, nothing of the kind happens. While we praise the manufacturer, mentally showering him with all kinds of awards. Ahead, a sewer manhole cover appeared. We aim at her with the wheel. So, hitting! Yes, the sensations are not the most pleasant, but bearable. We are convinced that the transformations went to the benefit of the KIA Ceed and the new chassis significantly surpasses the design that was present in the previous generation.
Let's summarize
In general, the behavior is confident, but I would like to wish the Korean engineers continue to work on improving the rear suspension and front suspension, and then car kia Ceed will be able to confidently "win" domestic bumps.
