The transportation market in Russia is constantly evolving. The number of vehicles and cargo is increasing. Therefore, carriers began to think about how to increase the carrying capacity of their vehicles. Previously, leaf springs were used as a solution to this problem - they were placed on a sprung box. But the trouble is that such cars became very tough. Such rigidity is not always needed in transportation. Fortunately, today the era of iron springs is a thing of the past. Now many trucks use air suspension. In today's article, we will look at how it works and whether it is worth installing it on the Iveco-Daily 70С15.

Description of air suspension

It is a type of suspension that allows you to manually adjust the vehicle's ride height. This system has long beenused on mainline trucks. As for the Iveco Daily 70C15, air suspension is not installed on it from the factory (both on the rear and on the front axle). This is a medium-duty truck, and multi-leaf springs are still used here. Only some versions of the Iveco Daily 70C15 are equipped with air suspension from the factory (as a rule, it is ordered as an option for a separate surcharge). If there is none, it does not matter, since it can be installed in Russia. Fortunately, many workshops are engaged in this.

What is special about this pendant? The key point is that air tanks are used to regulate the clearance. They are the main elastic element in the system. But it is worth noting that the cylinders do not completely replace the function of the springs. They also bear the load (in particular, the curb weight of the truck itself). But with an additional load, air cylinders are already included in the work.

How does it work?

This pendant consists of several elements:

• Air balloons. They hold the weight of the load and the machine itself, and also dampen vibrations on the go. They are a modern replacement for classic springs. Their other name is air springs. How they look at Iveco-Daily, the reader can see in our article. Thanks to a special design, the airbag can change its volume, thereby increasing or decreasing the vehicle's ground clearance.
• Compressor. Since the cylinders run on air, it must be inflated somehow. This can be done usingcompressor. The unit is powered by 12 V and is located in the cab or under the frame.
• Receivers. These are empty metal containers that temporarily store pressurized air. They are made in order to reduce the load on the compressor. The latter does not start up so often, since there is a certain volume for raising the springs in the receiver. But we also note that the system is not cyclical - when the cylinders are lowered, the air goes outside, and not back into the receivers.
• Wiring and connectors. These are air lines, sensors, nipples and solenoid valves. The electronics automatically activates the compressor if the pressure drops in the receivers. Swapping can be done on the go. And so that the pressure does not exceed the norm, the valve with the sensor automatically limits the supply of excess air.

What do owner reviews say?

Air suspension for Iveco-Daily 70C15 is a very useful purchase. Among the advantages of using such a suspension, reviews note its reliability. The system is very simple and does not break. Also, cylinders significantly reduce the load on regular springs. No need to strengthen and roll them when they sag from frequent use. Pillows retain their shape for a long time. If the air suspension kit is installed on the Iveco-Daily 70С15, you will not have to service the factory spring mounts (change silent blocks and earrings).

Another plus of such a system is a smooth ride. Yes, this characteristic is rarely applied to trucks. But with this suspensionno longer have to jump on the pits "on empty", as on reinforced springs. After unloading, you can reduce the pressure in the cylinders, and the machine will remain as soft as it came from the factory.

Because with air suspension you can change the clearance, the car will not be tilted to one side or the other. This provides good controllability. And at night it will not be necessary to set the headlights with a corrector, because the “tail” was heavily loaded at the company. After installing the air suspension on the Daily 70С15, the rear axle (no matter how much it is loaded into the car) will always be in the transport position. And if necessary, it can also be raised.

Iveco on the road

How does the Iveco-Daily 70С15 with air suspension behave on the go? Owner reviews say that such a truck is much easier to drive. Even with six tons on board, the car does not heel in corners, it drives like a glove. But if the task is to often carry overloads, it is worth installing an air suspension on the front of the Iveco-Daily 70C15. This will minimize the buildup.

Varieties

Iveco-Daily offers two types of suspension:

• single-circuit;
• two-circuit.

The first type is the cheapest and most popular among Iveco Daily owners. What are its features? Such a system is installed on only one axle. Thus, the front remains spring, and the rear axle is already air suspension. For the Daily 70C15, this is ideal, since more than half of the mass falls on the rear. This is also where the cargo is located. You can adjust the pressure in the circuit from the control panel, or by connecting to the nipple (ifinstallation without compressor).

As for the double-circuit, it is already placed on two axles. But is there any point in such an air suspension on the Iveco-Daily 70C15? Owner reviews say that it is not always necessary to buy a dual-circuit system. For its own purposes (and this is the delivery of cargo to interregional directions), Iveco-Daily will have enough of a single-loop suspension. In addition, its price is exactly 2 times lower.

4 contours

There is also a four-loop system. It can be found on business and premium class cars. The key feature of the four-circuit system is that each wheel is independent. The driver can adjust the clearance on each wheel separately. But this system requires more valves, hoses and fittings. Yes, and its cost starts from one hundred thousand rubles. It does not apply to commercial vehicles, so we will consider only single- and double-circuit systems.

Cost and equipment

How much is the rear air suspension for Iveco Daily 70С15? The simplest single-circuit system will cost the owner 22 thousand rubles. This is the cost of the kit without installation. The air suspension on the Iveco-Daily 70C15 is installed in service conditions in about 4-5 hours. The price of the service is about seven thousand rubles.

If an additional air suspension is installed on the Iveco-Daily 70C15 on the front, it is worth paying another 30 thousand rubles. The front has a slightly different chassis scheme, and therefore the design is slightly different. In this way,the turnkey installation of an air suspension with one circuit at Iveco-Daily will cost about 29 thousand rubles, and with two - already 60,000.

The kit includes the following items:

• air springs;
• plastic tubes;
• fitting;
• nipple adapters;
• air line fittings;
• compressor;
• pneumatic distributor.

As an option, a pressure gauge with an air pressure sensor in the circuit and a water separator can be installed.

Features

The air suspension for Iveco-Daily 70C15 has the following characteristics:

• material of air cylinders - rubber compound with nylon cord;
• working pressure range - from 1 to 8 atmospheres;
• critical pressure - 25 atmospheres;
• raise height (maximum) - 12 centimeters;
• lift force at 10 atmospheres - 3 tons.

Installation

Installation of air cylinders is carried out in the space between the inside of the frame and the spring. The air spring is fixed on the plates that come with the kit. The installation procedure consists of several steps:

• First, the air cushion is prepared. Before installation, a bracket with a metal plate must be fixed to it. The latter will serve as a fulcrum.
• Next, the mounting bolts of the outer fender bracket are unscrewed. This is necessary for further installation of the part in the frame.
• Installedpneumatic element in place. If necessary, drill a couple of holes to secure the part to the frame.
• Tighten the top and bottom bolts. The latter is attached to the mounting ear on the rear axle.
• Installed in the frame insert.
• Mounting bracket for brake hoses. They need to be moved to the side, because the air lines and fasteners of the cylinders will interfere with them.

Before you tighten the threaded connections, you need to check if the balloon does not touch the moving parts of the truck suspension. The next step is to connect the air lines. And then there is the control system. It is installed in the salon. All hoses and wires are fixed on plastic clamps. In places with high humidity, the wiring must be brought into the corrugation. If a control system is not provided, a priming nipple must be installed.

Where is the receiver fixed? It can be installed with the compressor in or under the cab. If there is a pressure gauge in the kit, it is pulled into the salon. It does not need to be connected to the wiring - it is purely mechanical.

Nuances

To install the nipple, you need to choose the appropriate place. The element can be placed in the body. To do this, a 10 mm hole is drilled, and a nipple is installed in it. Then the air line is extended to the pillows. A tee (T-fitting) should be used for branching. Please note that you must not fasten the air lines together with the braketubes. They need to find a separate place.

Align the end of the tube before connecting it to the fitting. It should be strictly perpendicular, without torn edges. A clamping nut is also put on the tube. It is twisted until it stops, after the fitting has fallen into place. If the Iveco-Daily 70C15 air suspension is being repaired, it is recommended to cut off part of the edge of the hoses when disassembling them. This will keep the system sealed. For better density, you can use a white fum tape. After assembling the system, all joints must be treated with a brush with soapy water. So we will determine where there is a breakdown in the system. The check must be done on the most inflated pillows (10 atmospheres).

What do we end up with?

After installing the air suspension, we get a car that will not be afraid of overloads. From the factory, the permissible load on the front axle of the Iveco-Daily 70С15 is two and a half tons.

If a two-circuit system is installed, this figure can be safely increased to three tons. The maximum load on the rear axle of the Iveco-Daily is 5.35 tons. With air suspension, the car will easily withstand seven, according to owner reviews. The air suspension for the Iveco-Daily 70C15 is a really useful purchase. But do not forget one nuance - tires. So that they are not overloaded, you need to choose tires in accordance with the load index. The owners say that the best choice would be Continental brand tires andMichelin.

Suspension Service

Does it need maintenance? The air suspension is very unpretentious. But the manufacturer recommends periodically inspecting the condition of the pillows. Their main enemies are dirt and sand, which settle at the points of contact between the cylinders. The smaller it is, the better. And on the eve of winter, it is recommended to treat air springs with silicone. You can use the most common, in the form of a spray.

With its composition, it will repel dirt and water, thereby extending the life of airbags. We also note that during operation it is impossible to lower the pressure in the pillows below one atmosphere.

Conclusion

So, we found out what air suspension is and why it is relevant for an Iveco-Daily truck. As you can see, this system allows you to significantly increase the carrying capacity of the car without compromising the frame and springs. In addition, the driver can independently adapt the rigidity of the air cylinders for a particular load. What type of suspension is best to install? Judging by the reviews, the best option is a single-circuit system. It pays off quickly and gives good results. If you modify the suspension, then only in this way. Installing an air suspension on the front axle will be an extra investment, according to many car owners.
