Power steering and electric power steering for Niva 2121-14

Operating principle of EUR and power steering

Before installing the amplifier in the VAZ 2121 with your own hands, let's look at the operating principle of the systems, starting with the power steering. When the steering wheel is in the central position, it is fixed using centering springs. In this position, the liquid circulates through all elements of the system, provided that the distributor is positioned correctly. In this case, the power steering pump operates in enhanced mode, which is due to the need to pump fluid through the system. Moreover, it always functions, regardless of whether the steering wheel is turning or not.

When the steering wheel is turned, the spool moves, as a result of which the element blocks the drain lines and liquid begins to flow into one of the cylinders. In this case, the piston, as well as the rod, are exposed to oil under pressure, which leads to the rotation of the wheel, as well as the housing, in a certain direction. The spool overtakes the device body when it stops moving, which indicates that the driver has completed the turning maneuver. In this case, the spool returns to its original position, and then the hose opens to drain the liquid.

As for the principle of operation of the electric power steering, the amplifier itself is mounted on the steering shaft of the vehicle. Its component parts are connected to each other using a torsion shaft, with an installed engine speed reading controller. When the driver turns the steering wheel, the torsion shaft twists, which is detected by the torque sensor. In accordance with the information received from the torque, speed and engine speed controller, the control module determines the compensation force, as a result of which it sends a command to the amplifier electric motor.

Operating principle of the hydraulic control system

How does power steering work? Its main element is a pump, which, using a belt from the crankshaft, sucks in oil and pumps it into the distributor. The latter, in turn, monitors the force applied to the steering wheel and, using a torsion bar (follower device), helps turn the drive wheels. When moving in a straight line, the torsion bar does not twist, so the distributor channels are blocked and the oil drains back into the reservoir.

Power steering is most often useful when parking and turning, making the work of your hands three times easier. We can also say that the mechanism weakens the transmission of microshocks from the road surface to the steering. The mechanism is also useful in case of a sharp drop in tire pressure. The disadvantages of power steering include the fact that it interferes with “feeling the car”, so designers need to achieve a compromise between informativeness and tightness of the steering wheel.

Foreign manufacturers conduct a lot of research in order to make the hydraulic booster light at low speeds and elastic at high speeds. To do this, German hydraulic boosters from ZF are equipped with pressure modulators, which limit the oil pressure in the operating circuit as speed increases. In addition, circuits with power steering driven by an electric motor are acceptable, which makes it possible to change the pump performance in accordance with the rotation of the electric drive. Sometimes the gear ratio is also changed.

The feasibility of installing EUR and power steering

Does it make sense to install an electric or hydraulic booster on your car? The only, but most important thing that such an installation can provide is to provide more comfortable driving. But you need to take into account that installing such a system is a rather complicated task that not everyone can cope with. At the same time, its cost is quite high, and if you cannot install the unit yourself, you will also have to pay a substantial amount for installation. Therefore, you need to decide whether it is profitable for you to install an amplifier from an economic point of view (the author of the video is Gennady Martynyuk).

Detailed instructions for installing electric power steering on a Niva

The procedure for installing the EUR with your own hands is as follows:

1. First you need to disconnect the battery.
2. Then the plug is removed from the steering wheel, the fixing nut is unscrewed, and the steering wheel itself is dismantled. You also need to unscrew the four screws and remove the plastic cover.
3. The mounting bolts are unscrewed and the instrument panel is dismantled. Disconnect the steering column switch plug, unscrew the bolt that secures it, and then remove the device.
4. Then the ignition switch wiring is disconnected, the device itself is removed, to do this, unscrew the two mounting screws and turn the key to position I.
5. The next step is to dismantle the steering column; to do this, you need to unscrew the steering shaft screw, as well as several mounting screws and nuts. Please note that Nivas use screws with shear heads, so the best option would be to apply notches using a chisel and unscrew them with pliers. Next, the column itself must be lowered down and then dismantled.
6. After this, unscrew the nuts on the mounting blocks with fuses and remove them. Also remove the relay cover located under the instrument panel.
7. The interior and engine compartment are separated from each other by a partition; it has an elastic plug, which must be removed. The EUR wire is pulled through the hole. Make sure that the installed wire does not come into contact with moving components of the wiper motor.
8. Under the dashboard itself, to the left of the steering wheel, there is an 8-pin connector, two gray wires are connected to it. The yellow-blue one from the EUR should be connected to this connector. Then, to the red block, which comes from the tidy, you need to connect the orange and blue-pink wires from the electric amplifier. Here, behind the instrument panel, you can find a ground bolt; you should connect the minus to it.
9. An amplifier bracket is installed under the tidy; the wiring from the ignition switch should be threaded into it.
10. Next, an intermediate shaft should be installed on the splines of the amplifier itself; remember that a ground should be connected to it in advance. The shaft itself should be securely fixed to the steering gear shaft and the EUR should be attached to the bracket. The shaft must not be pinched or too tight.
11. The assembly itself is fixed to the plate using two bolts and two studs; it is advisable to install nuts under them.
12. Next, the power and information connectors are connected to the amplifier.
13. In fact, the installation procedure can be considered complete. Now you need to reinstall the ignition switch and steering column switch. To install the steering column trim, it will need to be cut, for example, with a hacksaw. The steering wheel and dashboard are put in place. Then the wiring is pulled from the EUR to the battery. Please note that in the existing plug in the partition between the engine compartment and the passenger compartment, it will be necessary to increase the size of the hole. Perform a functional check of the equipment and check all connections again.

Preparation for installation

Alas, not every “ten” has a native electric amplifier. But this is not a problem, since the unit can be installed with your own hands. The work is not very difficult, because if you follow the instructions, you can do everything yourself perfectly.

The main advantage of self-installation is the impressive savings in money. The unit itself is expensive, and installation at a service station will cost almost the same amount.

At the preparation stage, you should purchase and prepare tools and materials in advance:

• New electric booster;
• Plate;
• Wiring kit;
• Promval;
• Cover and steering wheel;
• Set of different screwdrivers;
• Drill;
• Ruler.

Since we are talking about an electrical device, all kinds of oils and lubricants are not required here.

Installation

When everything is ready and you are ready to work, you can begin installing the power supply.

1. Remove the standard terminal from the block and insert it into the block on the harness.
2. Now the free terminal, which comes off the harness, is placed in place of the standard drive adjacent to the block. This will allow you to pass the standard wire between the two harnesses. The wire coming from the blocks has a rating of 50 Amps.
3. Next, disconnect the shaft casing, and then remove the ignition switch. Be sure to separate the switches. This stage is carried out carefully and slowly so that the casing does not crack.

1. Unscrew the steering rack mounting bolt and remove it.
2. Measure the length of the hole. If necessary, use a trim plate. We recommend recording the received parameters.
3. An electric amplifier must now be installed in the vacated area.
4. Please select the correct size shaft as it will not fit on the steering rack. To adjust the shaft, you will need a plate and a regrind for the shaft from Priora. By the way, when installing power units, elements from the Priora model are excellent. Take note of this.

1. After adjusting the plate, drill a larger recess than there is now. The shaft is a hollow structure, so any metal drill can easily cope with the task.
2. The plate is placed on the amplifier and the resulting depth indicator is checked. If everything fits, secure the structure with a small bolt.
3. Put all the switches back in place and start working on the wiring.
4. It is necessary to remove two wires from the interior that go directly to the battery. This is done through the left wing.
5. Remove the washer fluid reservoir and take a piece of wire. It will be needed to secure the wires leading to the battery. They are attached to the end of the opposite one, passed and pulled through both at once.
6. Remove the instrument panel and remove the red colored block. Carefully tighten the wiring into the under-panel space.
7. Now he removes the orange wire from the red box.

1. The red block is attached to this wiring and combined with the wiring from your electric amplifier. Don’t forget to place the end of the wiring with the “bare” terminal from the amplifier onto the free standard wire located in the red block.
2. The operation is performed in a similar way with the gray wiring, which is also located in the red block. It is pulled into its regular place and secured with terminals.
3. Next, we move to the battery, securely fix the black negative wire to the pink positive wire.
4. All that remains is to connect all the wiring from the power unit and start it up.
5. At this point, the installation is almost complete. You should definitely assemble all the components, return the components to their original positions - switches, casing, steering wheel, etc.

Customizing the EU

If you do not have experience in such work, you will definitely need to adjust the electric amplifier after completing the installation work.

Fitting includes the following activities:

• Steering wheel alignment;
• Elimination of all gaps formed between parts;
• Reducing the length of the power cable;
• Checking the installation of LED diagnostic sensors for the EU;
• Replacement of worn or damaged elements if necessary and available.

Features of installing power steering

Briefly about the features of installing power steering on the Niva:

1. First, the central nut of the steering wheel is unscrewed, after which it is dismantled. A puller may be required to remove the nut. The universal joint is also removed from the steering wheel.
2. Then the fan strap is loosened.
3. After installing the hydraulic booster, you need to fill the system - to do this, unscrew the expansion tank cap and fill the system with oil to the required level. After this, the steering wheel should be turned to its extreme positions several times with the engine turned off, this will get rid of the air lock in the system.
4. When bleeding the system, it is recommended to jack up the front of the car or disconnect the steering rod from the bipod. Next, the engine is started and the required amount of liquid is added to the system. If you notice that after adding the oil it begins to foam, this indicates that air has entered the power steering hoses. Then you will need to turn off the engine and wait a while until the bubbles stop coming out.
5. The procedure is carried out almost identically to installing the EUR, only there are some nuances. Before you begin the process, carefully read the service book that comes with the kit (the author of the video is the Andrew Humm channel).

Price issue

Wanting to install an EU on a VAZ 2110, many car owners are interested in how much the installation will cost them.

We cannot say the exact prices of such services at car services, since each service station has its own pricing policy. If you plan to do the installation yourself, then we suggest that you familiarize yourself with the approximate price list for everything that you will need during the work process.

Electric power steering VAZ 2110

The steering wheel of a car is the main means of control for a motorist. Driving skill depends on the ability to turn the steering wheel. Today, the automobile market is filled with many different models of different classes: from minivans to heavy trucks. Maybe this is what led to the creation of the EUR. It is noteworthy that the electric power steering on the VAZ 2110 can significantly increase the convenience and efficiency of the steering wheel. Installing electric power steering on a VAZ 2110 is a topical and in-demand issue lately.

The nuances of adjusting the steering wheel position

As for the adjustment, it is usually performed if the driver is not satisfied with the height position of the steering wheel. To adjust the EUR, you need to grind off the edges of the shaft to the required dimensions or install a gasket between the mechanism body and the plate.

Price issue

As for the price, it depends on the type of amplifier, as well as the store where the kit is purchased. The cost of an ESD kit today averages about 27-32 thousand rubles. As for the hydraulic booster, on average the installation kit will cost the buyer from 31 to 40 thousand rubles. You can assemble a power steering system from different parts from different cars, for example, install a column from an Opel or Nissan, and a pump from a BMW or other car models. But you will have to tinker, since you will need to perform more than one alteration.

The power steering of the Chevrolet Niva is filled with Pentosin Hydraulic Fluid CHF11S VW52137. It is filled for the entire life of the car and does not need regular replacement.

In case of fluid replacement, in addition to the original one, you can use, for example, GM (article 19 40 715).

special for power steering. There are many of these, not necessarily the original one, since it is expensive and can still be difficult to find.

Instead of Pentosin, you can fill it with Mannol CHF - its analogue. You can also add Dexron IID while flushing the system.

— Friends Shnivovody! I’ve been driving my car for a year now, using it both in tail and mane, but I also don’t forget to groom and lily it. After the purchase, I gave it a complete makeover, replacing all the fluids and some minor components. Over the course of a year, the amount spent on repairs did not exceed 5,000 rubles, and this takes into account the fact that the car is 12 years old.

So, after all the procedures, I remembered that I forgot to change the fluid in the power steering, it was a terrible black color. And then the question arose, what kind of liquid was poured into the Chevy Niva in 2004 and is there a difference in what kind is poured now? I ask you, friends, to help me resolve this issue, what do I need to fill, what volume and how to properly change the old fluid, do I need to flush this unit with anything? Thank you in advance!

Technical characteristics of the VAZ 2123 engine

The VAZ 2123 power unit has a working volume of 1690 cubic meters. cm. It is naturally aspirated and runs on gasoline fuel. His weight is 127 kilograms. The electronic fuel injection system increased engine power to 80 hp, and the torque is 127 NxM, which becomes available at around 4000 rpm.

On the highway the car can reach a speed of 140 km/h. A five-speed manual gearbox is responsible for shifting gears. Highway consumption does not exceed 8.5 liters per 100 km. In the city it increases to 14 liters per 100 kilometers. In such an engine, for its stable operation and responsive traction, it is recommended to fill AI-95 gasoline.

A timing belt with a hydraulic chain tensioning system requires increased oil pump performance. To increase productivity without increasing power, engineers reduced the number of teeth on the pump drive gear.

To lubricate the engine, 3.5 liters of oil is required. Both synthetic and semi-synthetic oils are suitable. The only thing that requires attention is the viscosity indicator, which must correspond to the 5W30 index. To preserve the life of the Chevrolet Niva engine for many years, it is recommended to change the oil every 10,000 km.

Removal

Over time, the power steering wears out or breaks, so it needs to be replaced, but to do this it needs to be removed, this can be done as follows:

1. The first step is to remove the belt that drives the power steering, as well as the protection of the pan with mud flaps of the engine compartment.
2. We pump out all the liquid from the tank
3. We take a screwdriver and stop the pulley, loosen the bolts that secure it to the flange
4. Unscrew all the bolts and remove the pulley
5. Drain the remaining liquid
6. Disconnect the hose
7. Unscrew the bolt fitting
8. Seal the hose tip with a special washer
9. We unscrew all the existing fasteners, including the top bolt, and remove the pump.

After the pump is removed, it can be repaired.

Story

I have already said many times that I do not do tuning or modifications for the sake of the process. Only if there are problems. In this case, it all started with the “collective farmers” of AvtoVAZ. For a very long time, the plant installed German ZF power steering pumps on the assembly line, and then suddenly the Russian version came into use. As usual, the plant was not going to give any explanations, so I had to turn to another source, the manufacturer ZF.

A technical seminar was held in St. Petersburg, organized by this company, and I asked the German a question about this situation. Directly at the lecture (that is, the official position), the German specialist said that this is a trade secret. And during the lunch break, when I addressed him in German, he straightened up and said the following. Quote.

Along with the supply of pumps, we gave a recommendation to AvtoVAZ on what SHOULD be poured into the system. At first, the plant filled in an approximate analogue of the liquid that we recommended, and then suddenly it began pouring green Pentosin. The result was not long in coming - leaks and a humming sound when turning. But the funny thing is that all these “supposedly” warranty cases were transferred to the shoulders of ZF.
