Racks with adjustable height and rigidity. Adjustable shock absorbers
Motorists should only be glad of healthy competition among vehicle manufacturers. They are constantly looking for security and technological innovation. This applies to components and assemblies of machines, including the settings of shock absorbers.
The developers offer new combinations of adjusting the height of shock absorbers for stable operation of the car’s suspension and comfortable movement on roads with different surfaces.
Cars are equipped with strut bars, but few owners understand how adjustable coilovers work, including electronically controlled external elements of the suspension system. This will be discussed below.
How adjustable coilovers work
You need to understand that there are differences in suspension designs, and considerable ones. Therefore, before choosing external suspension elements, you should pay attention to the manufacturer’s recommendations. It is important to know how the system is configured and the features of configuring external elements.
Most vehicles are equipped with oil shock absorbers with a double rod, which have to be changed periodically.
More powerful cars, in particular SUVs, have gas-filled monotube suspension elements.
The operating principle of the adjustable elements is as follows.
It is the prerogative of the piston to regulate the fluid pressure in the shock absorber. It is semi-permeable with small holes. A certain amount of oil passes through it.
Because the holes are microscopic, liquid leaks out in small quantities, and the piston is able, in this situation, to compress and absorb force.
The peculiarity of adjustable kits is that you can change the holes themselves and their size. In other words, control the efficiency of force absorption.
On a note.
If there is a desire or need to adjust the suspension, you should adjust the external elements of the suspension system.
It is important to understand that the system is very complex. This requires special knowledge and practical skills.
If you prefer an aggressive driving style. Do you enjoy cornering at speed? Enjoy driving over rough terrain? Then you need to adjust the height of the suspension elements.
Therefore, for this, more resistance is needed. When moving within the city, adjustments and settings from the manufacturer are enough. The algorithm is as follows:
- The car is lifted onto a lift.
- On the back of the element there is a special dial, where you can see a scale with divisions in the range from 1 to 10, as shown in the figure.
- By setting the disc to a higher number, you are thereby reducing the size of the holes in the piston. The result of the manipulation is increased impact strength.
Perhaps many people do not know that it is possible to change the settings themselves. Unless you're a Schumacher pretender or an enthusiast, there's probably no need to adjust the coilover arrangement.
On the other hand, you need to understand that the comfort and safety of all road users depends on the correct settings. The driver controls the dynamics of the car.
The most accessible and simple elements are those in which the stationary support is replaced by 2 springs and connected with a thread.
The design makes it possible to adjust the vehicle's ground clearance by moving the springs up or down. All shock absorbers and springs are made of high-strength steel and are able to withstand high constant loads on the front part of the car body.
What else can you do? Change hardness. Such shock absorbers are more expensive than non-adjustable models. Their pitch and stroke of the rod depend on changes in ground clearance. These shock absorbers, manually adjusted and coilovers with automatic adjustment, can affect the vehicle's speed and handling.
Electronically controlled designs
The suspension stiffness of any car is determined by:
- Springs.
- Shock absorbers.
You can vary compression in two ways:
- Change the elasticity of the springs.
- Change the hardness of the coil.
Hardness changes in three ways:
- Changing the diameter of the passage hole.
- Changing the viscosity of the technical fluid.
- Adjusting the gas pressure.
Imagine that the terrain changes periodically. So, you need to stop and adjust the characteristics of the shock absorbers every time? The situation seems absurd, and the tasks of changing effort and rigidity are a myth?
Not certainly in that way. To quickly change characteristics, “electronic brains” come to our aid.
Electronically controlled coilovers have been mass-produced since the beginning of the year 2000. Initially, they were installed exclusively on expensive premium cars. Today, they are available for cars in the mid-price segment. It is interesting that such monsters as:
- Bilstein.
- Delphi.
- Koni.
- Monroe
and others, take one of the three parameters as a basis and work to improve it.
What's going on in the Russian market? If domestic enterprises are moving in this direction. Yes, there are successes and considerable ones.
In Russia there is a company called Sistema Technologies, which occupies a leading position in the industry. Better known as “ss20”, it offered the Russians electronically adjustable coilovers. This will help change driving in the future. News, articles, tests, brands of the Volzhsky plant are published on the Internet.
Perhaps in the near future, electronically controlled designs will be available for all manufactured vehicles. In any case, the future is theirs.

The Sistema Technologies company, being one of the industry leaders, with sufficient authority and experience in the design of suspension parts, better known under the SS20 brand, for the first time in the domestic automotive industry, presents to your attention the Skayton adjustable suspension system, revolutionary in its class.
Adjustable stands- one of the main solutions in modern cars, allowing to satisfy the most demanding requirements of motorists, increase comfort and traffic safety. The SS20 Electronically Adjustable Shock Absorbers are a new generation of suspension that takes handling and driving safety to a new level and makes everyday driving a thrilling experience.
Adjustable suspension is an alternative solution for everyone who prefers to live according to the “ALL INCLUSIVE” principle.
Let's think about it - how do we choose racks? Many people come to the market and, without thinking too much, choose what is available. Some people trust the advice of a mechanic or a friend, while others are interested in the seller’s opinion. But, be that as it may, neither the first, nor the second, nor the third can choose the racks that best satisfy everyone’s requirements!
Why is this happening? Because setting up shock absorbers is always a certain compromise - it is impossible to make struts that would simultaneously provide the car with stability and the ability to corner at high speed, eliminate rolls and dives when braking in a sporty driving style, and at the same time ensure smooth comfortable movement and minimal shocks during everyday driving. driving.
Very often there are cases when a person, having bought “Highway” shock absorbers, after some time realized that he needed “Comfort” or vice versa. So then think about how different the imaginary and real sensations of car comfort are for each of us. In addition, many of us drive our cars differently at different times, depending on road conditions, vehicle load, mood, etc. And the main thing is how to determine as accurately as possible the line separating “like” from “dislike.” After all, the choice needs to be made once, when purchasing a set of shock absorbers.
The Sistema Technologies company has found a solution - these are electronically adjustable Skayton shock absorbers.
The system is adapted to any road conditions, with a large margin of safety, operating in a wide range of temperatures, with various suspension settings - from comfortable to emphatically sporty. We tried to make the system as simple as possible, which had a positive effect on both the reliability and the cost of Skyton. This system regulates the stiffness of the shock absorbers, not the height of the car.
The development is patented and certified, and today it is an exclusive offer on the market.
The “Skayton” system allows you to adjust shock absorbers directly from inside the car, and this can be done even while driving; there is no need to stop, climb under the hood or under the fender of the car to a dirty shock absorber and twist something there. Everything is done simply and quickly - just change the settings using the control panel from minimum to maximum and you get a completely different car.
If you want to go for a ride today - set the HIGHWAY setting and get minimal body roll when cornering and changing lanes. The suspension becomes denser, handles road unevenness more accurately and more rigidly. The car responds better to steering inputs and handles clearly and predictably.
And on Saturday - the prose of life - you need to take your mother-in-law (oh, sorry dear - mom) to the dacha (the dacha season has begun!). Here you will get a comment for every bump. And then it’s better to set the setting to soft and try to deliver the “precious cargo” and seedlings in addition as smoothly as possible.
Adjusting the shock absorbers allows you to adapt the suspension to changes in vehicle load, road conditions and speed. Obviously, a suspension that is well suited to driving on rough roads will not be optimal when driving on the motorway at high speed, and vice versa.
Let's check the efficiency of the system using a vibration stand (MAHA stand). Let’s check the operation of the suspension with electronically adjustable “Skayton” shock absorbers one by one in the most commonly used “Comfort” and “Highway” modes on a Lada Priora VAZ 2172 (station wagon). When carrying out the test, the stand evaluates the amplitude of wheel movement in resonant mode, and also evaluates the effectiveness of damping suspension vibrations (damping) by shock absorbers. Typically, the minimum acceptable level of vibration damping efficiency is 40-50%, depending on the make and model of the vehicle.
Figure 1. Front axle oscillation graph with “Comfort” settings. The amplitude of wheel oscillations is 29 and 32 mm. The efficiency of suspension vibration damping by shock absorbers is 65% on the left and 63% on the right, respectively.
Figure 2. Graph of vibrations of the front axle with the “Highway” settings. The amplitude of wheel vibrations is 21 and 23 mm. The efficiency of suspension vibration damping by shock absorbers is 82% on the left and 80% on the right, respectively.
The vibration test readings confirm the subjective driving sensations. In the “Highway” mode, relative to “Comfort”, the amplitude of wheel vibrations is reduced by 28%. Accordingly, the driver and passengers feel a decrease in roll when turning and changing lanes and a decrease in dive during acceleration and braking. The suspension becomes more “collected”, which is reflected in the graph and in the figures of the effectiveness of damping suspension vibrations by shock absorbers. This figure increased by 26%.
Thus, with an increase in the rebound force (stiffness) of shock absorbers from “Comfort” to “Highway”, the amplitude of vibrations of the unsprung masses decreases and the efficiency of damping suspension vibrations by shock absorbers increases.
Having an adjustable Skyton suspension, on any road, at any speed and with any load, you can provide the necessary suspension settings for yourself and your passengers, ensuring comfortable driving conditions.
In addition, the electronically adjustable Skyton suspension is also a very profitable purchase. In fact, you get an “ALL INCLUSIVE” suspension, which can be both sporty and comfortable at the same time, combining both high handling and smoothness.
Buy telescopic stands from the Vostok Formwork company. But no matter how good the formwork is, for a durable and monolithic component of the building, one more component will be needed, these are high-quality supporting and auxiliary elements.
Floor formwork on telescopic racks - as a method of pouring monolithic floors concrete
So, you have decided to buy formwork stands from the manufacturer, our engineers will calculate the quantity you need in a short time
Let us describe a simplified diagram of this design:
It looks like this - 1) First of all, a tripod is installed, then a stand is attached to it. In laying a wooden beam BDK for formwork uses a uniform formwork or the so-called crown. 2) After installing and securing the racks, a plywood deck with cut-offs is laid on top, then a concrete mixture is poured onto it. Such a system is floor formwork on telescopic stands.
Advantages of using telescopic stands
- Easy to transport
- Quick installation and disassembly of the structure (including with a unifork and a tripod)
- Safety and durability
- Applicable even in harsh climatic conditions
The use of formwork on telescopic stands in construction makes it possible to obtain various monolithic structures with a flat surface, without any special additional processing.
Telescopic formwork stands - all sizes at low prices
Telescopic stand for formwork – serves as a support for horizontal panels of structures. It can also perform the fixing function of horizontal components of formwork systems for some time. We offer telescopic formwork stands in the following standard sizes: 1700, 3100, 3700, 4200, 4500 and 5500. Their height is adjustable within these limits. In our company you can reallybuy telescopic stands from stock.
The main criteria for a telescopic construction stand in production
Function construction tripod lies in the reliable and quick installation of the racks - it helps to firmly and strictly vertically fix the support, and this in turn reduces horizontal loads and vibration at the time of supplying the solution.
The construction formwork is fixed in the upper part of the rack and acts as element holding the plywood-wood beam BDK-1. At the same time, it can serve as a holding element for one or more beams, if they overlap. This unit at first glance seems simple, but in fact it is key - after all, the entire flood deck is supported on it. Therefore, you should take a responsible approach to choosing a construction fork.
Today, there are a huge number of companies on the market offering racks and other components of floor formwork, but only a few can offer their customers products that meet the stated load-bearing standards. Our company is one of the few in Moscow that supplies reliable and first-class equipment (including telescopic stand, price which depends on its size). Well, the answer to the question is " How long does the formwork last?" you will find on our website in the "Questions/Answers" section.
And if you can't affordbuy volumetric formwork, then it is possible for us for formwork.
Table. Loads on the telescopic stand
In this table we have indicated the maximum load-bearing values for racks in kg. When calculating the loads on the formwork system, take into account the demand factor from 1,2
