From what to put the gur on the VAZ 2107. Installation and connection of the power steering on the "Seven": to turn the steering wheel "with one finger. Video: installation process

VAZ "classic" does not provide such an option as a power steering. If the control does not require much effort when driving on the road, turning the steering wheel at low speed, maneuvering in the parking lot, is quite difficult. To turn the steering wheel with “one finger”, you can install an electric power steering on the VAZ 2107. With the apparent complexity of the device, installation and connection do not require special skills and do not take too much time. To install the power steering, you will need a set of keys, a drill and an electric power steering with wires and fasteners.

Why put the EUR on the VAZ 2107

The electric amplifier on the "seven" is installed in such cases:

• to facilitate control when the machine is driven by the fair sex;
• for safety, convenience and comfort of management;
• as an element of car tuning;
• to make driving easier for the elderly or people with health problems.

Types of power steering

On modern machines Two types of power steering are used: hydraulic and electric (electromechanical) power steering. In short - power steering and EUR.

Power Steering is based on the use of pressure working fluid(oils). The hydraulic booster system includes a pump, supply pipes, reservoir and oil. The pump creates oil pressure that acts on the mechanism, making it easier to turn the wheels when the steering wheel is turned. The design of such an amplifier is quite complex, installation is laborious, and the amplifier itself requires regular maintenance. Only if these conditions are met, the power steering will delight with the ease and softness of work.

Installing a power steering on a machine whose design does not provide for power steering is a complex and very expensive procedure that requires the installation of additional parts and major changes to the steering design. Therefore, the installation of a hydraulic booster on the VAZ 2107 is not justified.

The electromechanical amplifier does an excellent job of its functions and costs almost half as much as the power steering. Installation of the EUR on the VAZ 2107 is not very laborious and does not cause any particular difficulties. The electric power steering does not require periodic maintenance and is more reliable and durable than power steering. It does not need to work special liquids and pumps, it is enough to connect the node at onboard network car. Therefore, it is this type of power steering that the owners of the “sevens” install on their cars.

Electric power steering on the VAZ 2107: compatibility and equipment

Electric amplifiers that can be installed on the "seven" are produced by the "Aviaagregat" plant, located in Makhachkala. The EUR is intended for installation on the VAZ 21214, but the design allows it to be used in the steering of any “classic”. The electric booster is mounted directly on the steering column of the car.

The EUR delivery set includes:

• electric booster mechanism;
• bracket for mounting the EUR on the steering wheel of the VAZ 2107;
• intermediate cardan;
• wires;
• fasteners;
• decorative harness.

The electric booster on the VAZ 2107 works according to the following scheme: the electric motor works synchronously with the driver turning the steering wheel, creating an additional moment that reduces the effort to turn the wheels. The EUR amplification factor is 5.7, that is, after installing the EUR, instead of a force of up to 20 kg, efforts of up to 3.5 kg will be sufficient.

The amplifier uses the feedback principle. It looks like this:

• the moment sensor determines whether the driver turns the steering wheel and the direction in which the steering wheel rotates on the VAZ 2107;
• the EUR control module reads data on engine speed, driving speed, ignition key position, processes it according to the programmed program and issues a control signal to the electric motor;
• the electric motor rotates the cardan of the steering wheel, facilitating the efforts of the driver.

The speed sensor ensures that the gain matches the current vehicle speed. At low speeds, the steering gain is lower, it becomes harder to turn, and at high speeds, less effort is required to turn the steering wheel.

The electric booster starts working 5 seconds after the car ignition is turned on.

If there are signs of a malfunction of the EUR, the automation turns it off, transferring the car to the standard manual control mode, which ensures 100% safety in the event of a breakdown.

Installing the EUR on the VAZ 2107

Before starting work, it is necessary to remove the terminals from the battery in order to avoid a possible short circuit.

The procedure for installing the EUR is as follows:

Almost all operations for the installation and connection of the EUR are carried out in the interior of the car. The work takes 2-3 hours. The warranty for the EUR of the Makhachkala plant is 1 year. This best option amplifier in terms of price-quality ratio.

Note: on the VAZ 2107, you can install the EUR from Priora. To do this, you need to make or buy a special adapter plate and cardan.

Inspection after installing the EUR on the VAZ 2107

The installation of an electric booster is formally considered to be a change in the design of the car and is an obstacle to passing maintenance without the appropriate certificates of conformity. It will not be possible to hide the fact of installing the EUR on the VAZ 2107 - the device clearly manifests itself when checking the steering wheel play. This may be the basis for refusing to issue a paper on passing a mandatory technical inspection.

In order to pass a technical inspection in accordance with the law, it is necessary to find an official letter from the manufacturer about the compliance of this EUR model with the requirements for installation on a VAZ 2107. This letter (copy) must be carried with you when passing a vehicle inspection.

Also, for maintenance, a document is required confirming the installation of the EUR at a VAZ-certified car service.

If these two documents are available, the employees of the technical inspection station do not have the right to refuse to issue a certificate. In a conflict situation, a written refusal should be required indicating the reasons.

If you decide to install an electric power steering on a VAZ 2107, then you have two options.

1. Take it from Priora or Niva, modify it and paste it. It will cost about 20-23 thousand rubles.

2. Or buy an electric power steering specifically for the VAZ 2107. Purchase and installation will cost about the same amount.

We cannot specifically advise on what to choose, because (regarding the installation of Nivovsky or Priorov electric amplifiers), someone says that they fail unexpectedly. Some argue that this wedges the steering wheel. This is dangerous when driving, as the vehicle cannot be steered.

As for the factory EUR, so far no complaints have been heard.

Is there anything that needs to be done during installation?

In any case, whichever option you choose, you will still have to adjust the gearbox speed sensor. If this is not done, then when starting off and at low speeds, you will not notice any changes. That is, turning the steering wheel will still be just as hard. And only when you pick up high speed, the steering wheel will give in to you with less resistance.

And if there is no speed sensor, then it must be installed. Here's what it should be: 6-pulse feedthrough from 214 Niva (usually comes with a factory electric amplifier)

In addition, some more changes to the design will need to be made. Here they are:

• take another suction cable (included with the electric booster from the VAZ 2108) and transfer it;
• replace the gearbox - take one so that it has a short worm shaft, but the bipod remains native;
• if the VAZ 2107 is with a contact ignition system, then you need to put the MUR1100E diode.

What else is included in the EUR package for the seven?

In addition to the EUR itself, the kit includes:

• steering column cover, ignition lock, steering column switches - all this from the VAZ 2110;
• speed sensor;
• suction cable;
• fasteners;
• passport and instructions on how to install the EUR.

On cars of the "classic" series, the installation of power steering was not provided. All these machines use steering gears. And the electric power steering on the VAZ-2107 is a good tuning element. While driving on the highway, the car is very easy to control, the steering wheel rotates effortlessly. But as soon as you slow down, make maneuvers in the parking lot, it becomes more and more difficult to turn the steering wheel.

It is in order to facilitate maneuvering at low speeds that it is necessary to install an electric power steering on the VAZ-2107. This is a separate unit that is mounted in the steering column. Its installation and connection will not take much time. All you need for installation is a set of keys, an electric booster kit with all fasteners and wiring, and a drill.

Benefits of using an electric booster

On "classic" cars, the Priors electric power steering is installed without any problems. But for this you will have to additionally buy a plate and cardan. Tasks with which the EUR copes:

1. Increasing the level of safety, comfort and ease of driving.
2. Facilitate control during maneuvering. This is especially useful for women, older people, novice drivers who find it difficult to turn a tight steering wheel.
3. The electric amplifier acts as an element of tuning.

But even if you have been driving for many years, you are unlikely to be able to refuse such an improvement in your car. After all, the installation of an electric power steering will make it easier to move along city streets.

Why not hydraulic?

There are two types of power steering:

1. Electromechanical.
2. Hydraulic.

The operation of the hydraulic power steering creates high oil pressure in the system. The design of the hydraulic booster consists of supply pipes, a pump, a special reservoir and a working fluid. With the help of the pump, oil pressure is created, it affects the entire mechanism, as a result of which the turning of the wheels is greatly facilitated.

Therefore, rotate steering wheel it will be much easier. In general, the design of the hydraulic booster is very complex, installation takes a long time, all mechanisms need to be serviced regularly. Only in this case the hydraulic booster will work perfectly.

If the car does not provide for the installation of a hydraulic booster, then it is very difficult to install it. You will have to purchase additional parts, as well as make very serious changes to the steering mechanism. It is for this reason that it is not advisable to install a hydraulic booster on the "seven".

Electrical Amplifier

It has one big advantage - the cost is almost half that of a hydraulic booster. Mounting the device on the "seven" is very simple, there will be no difficulties. In the case of using an electric amplifier, it is not necessary to carry out a technical examination, it is very reliable and durable.

Unlike a hydraulic booster, for normal operation it is not required to fill the liquid, maintain the pump and pipelines in working order. It is enough just to connect the device to the vehicle wiring. It is for these reasons that such a power steering design is installed on cars of the “classic” series.

Equipment

Without alterations, you can install the Priors electric power steering on the Seven. With the same success, products manufactured by the Aviaagregat plant are used. Device complete set:

1. Direct power amplifier.
2. Intermediate cardan shaft.
3. fasteners.
4. Wiring.
5. Brackets for fastening the electric power steering on the steering wheel of the "seven".
6. Decorative harness.

When buying, be sure to check the complete set of the device. If there is no item in the box, then you must immediately inform the seller about it. Otherwise, installation problems will occur.

How an electric booster works

The electric power steering on the VAZ-2107 starts to work and creates additional torque, which reduces the effort required to turn the wheels. Moreover, it starts to work at the same time as the driver turns the steering wheel. The device is able to reduce the load required to turn the steering wheel by 5.7 times.

In other words, if you applied a force of 20 kg before installing the device, then after that only 3.5 kg is enough for a similar action. Stages of device operation:

1. The torque sensor determines which direction the driver is turning the steering wheel.
2. The control unit allows you to read all data related to engine speed and vehicle speed.
3. With the help of an electric motor, the propeller shaft of the steering mechanism rotates. As a result, the effort required to turn the steering wheel is reduced.

With the help of a speed sensor, a normal relationship between the gain of the device and the intensity of the vehicle is ensured. If the speed is low, then it becomes harder to turn the steering wheel. Therefore, the control unit understands that it is necessary to increase the gain. Conversely, if you are moving at high speed, then you need to apply less effort. Therefore, the electric power steering is not involved in the steering.

The start of the device starts 5 seconds after the driver turns on the ignition. If suddenly there was any breakdown in the electric amplifier, automatic system control will turn it off, as a result, the car will be transferred to manual mode. This ensures 100% safety in case the device breaks down. Therefore, you can not worry about the safety of your life.

Installation of an electric amplifier on the "seven"

The block diagram of connecting an electric amplifier (can be used with any VAZ car) is shown below.

To install an electric power steering on a 2107, you need to follow these steps:

1. Disconnect the battery to the battery so that there is no short circuit during work.
2. Remove the screws that secure the cover to the steering column.
3. Remove the steering cardan, put in its place a new one, which is included in the device kit.
4. In the instructions, you will definitely find a diagram according to which it is necessary to drill holes with which the amplifier case will be fixed.
5. Fasten the entire mechanism.
6. Connect the wires coming from the engine speed and speed sensors.
7. Connect the power to the device using a fuse.
8. Then you need to install the casing in place and connect the battery terminals.

Installation work will take no more than two to three hours. The guaranteed service life of the electric amplifier is one year.

How to pass an inspection

The electric power steering on the 2110, as on the seven, must be installed correctly. The problem is that with such tuning, you are formally making changes to the steering design, which is prohibited by the rules. traffic. As a result, you may encounter some difficulties during the inspection.

You can try to hide the fact that the car has an electric booster. To do this, it is enough to disconnect it from the power supply. If this is not done, then during the diagnosis of backlash, the mechanic will understand that a revision has been made. And he will not give you a technical inspection coupon. Therefore, in order for everything to be legal, you need to print out a letter that is issued by the manufacturer of the EUR. It says that a particular model of the electric amplifier meets all the requirements that are necessary for installation on the VAZ-2107. A copy of this letter must be carried with you during the MOT.

Along with this letter, you must have a certificate issued by the car service where the device was installed. Only if you have all these documents, you can be issued a diagnostic card. If even if these documents are available, you are not given a diagnostic card, you must demand a refusal in writing with an exact indication of all the reasons. If the electric power steering on the VAZ-2107 is installed correctly and in compliance with all requirements, refuse to issue technological map you can't.

In today's article, we will talk in more detail about devices that reduce steering forces. Special attention we will turn to power steering, intended for installation on cars of the VAZ 2107 brand.

In today's article, we will talk in more detail about devices that lower the resistance on the steering wheel. We will pay special attention to power steering, intended for installation on cars of the VAZ 2107 brand.

So, this article contains answers to such fairly common questions:

• What is a hydraulic booster?
• What is the principle of operation of the hydraulic booster?
• How is the power steering?
• How should the hydraulic booster be installed on a VAZ 2107 car?

Basic information about the hydraulic booster

The power steering or, as it is abbreviated as the power steering, is the hydraulic system of the car, part of the steering mechanism, which is designed to facilitate the management of the direction of movement of the vehicle while maintaining the necessary feedback, as well as ensuring the stability of operation and the uniqueness of the given trajectory. In addition, the power steering is designed so that in the event of its failure, the steering will function, but the steering wheel in this case will spin a little harder. Power steering is one of the most important steering elements in any vehicle. The main purpose of the power steering is to create side forces at the moment the steering wheel is turned due to the presence of an electric drive. Almost all modern vehicles are equipped with power steering.

What distinguishes the power steering for a VAZ 2107 car? Motorists with experience identify several main advantages of the power steering on a VAZ 2107 car, such as:

• High level of reliability;
• High information content;
• Low fuel consumption;
• Ease of adjustment specifications guides.

It is also worth paying your attention to the fact that the hydraulic booster has two schemes, such as transferring forces to the river or the steering wheel. Motorists distinguish two systems of such amplifiers:

• With parallel drives, that is, it transfers forces from the engine to the steering structure by means of belt transmission. In this case, force is simultaneously transmitted to the roller and steering rack.
• With two gears, which are a single unit, combined includes a steering wheel and power steering. In the power steering is an asynchronous type motor. The steering rack is equipped with two sections of teeth, one of which is an amplifier drive.

Power steering device on a VAZ 2107 car

The power steering for cars of the VAZ 2107 brand includes the following main elements:

• Pump. Thanks to this device, the circulation of the working fluid and pressure is ensured.
• with distributor. With its help, an air flow is provided, which directs the oil into the required cavity of the hydraulic cylinder or back into the barrel.
• Hydraulic cylinder. With the help of a hydraulic cylinder, the fluid pressure is converted into the movement of the piston and rod.
• Oil that transmits force from the pump to the hydraulic cylinder, and also lubricates all friction pairs. It is located in a plastic barrel with a built-in filter medium, and a probe is placed in its cork that determines the liquid level. In addition, all nodes combine high pressure hoses that circulate fluid in the booster system.

The power steering provides steering of the vehicle in the following modes:

• When cornering at high or low speed;
• Return car wheels in the middle location and their maintenance in this state;
• When turning.

The installation of a power steering on cars of the VAZ 2107 brand is simply necessary, because thanks to this equipment, the steering wheel is turned.

And thanks to the torso, the transmission of torque to the steering system is ensured, at the same time, the twisting and the angle of rotation of this wheel are measured. To carry out such measurements, special sensors are used, and the information received is transmitted to the hydraulic booster. This is how the operation of the hydraulic booster is maintained in the required mode. After that, the torque goes to the steering mechanism and the drive wheels of the car. Turning at low speeds is typical for parking vehicle, and the steering angle of the car is not small. The torque is provided by the electronic steering circuit with the help of the maximum functioning of the auto engine.

How is the power steering installed on a VAZ 2107 car?

Due to the lack of power steering on a VAZ 2107 car, many motorists decide to install the power steering on their own car. Very often, experienced motorists claim that power boosters for Niva and Priora often break down, and sometimes the steering wheel jams. Naturally, this is very dangerous when moving a vehicle, both for you and other road users. That is why the ideal option would be to install factory hydraulic boosters on VAZ 2107 cars.

Naturally, it will also be necessary to adjust the gearbox speed sensor, otherwise the driver will not notice any changes at the beginning of movement at low speeds. That is, the steering wheel will be a little harder to turn. At the moment of a set of high speeds, the steering wheel will pass to the owner of the vehicle with a small level of resistance. Also, if you do not have a speed sensor, then it will also need to be installed.

The most difficult procedure is to replace the gearbox. To carry out this procedure, it will be necessary to cut a hole in the front shield and slightly modify the bipod. To install the gearbox, it will be necessary to install the bracket to which the power steering pump is screwed to the head of the cylinder block. After that, you need to change the pulley on the crankshaft, and the drive for the pump using a belt drive. Next, you will need to consider the location expansion tank, and also connect all hoses and fill in oil. In addition, the kit for installing the power steering includes detailed instructions by installation. Let's look at the main advantages and disadvantages of the power steering on VAZ 2107 cars. So, the main advantages of the power steering for a VAZ 2107 car include:

• Reducing the number of steering wheel turns;
• Decreased steering effort.

The main disadvantages of the hydraulic booster for cars of the VAZ 2107 brand include:

• Great cost;
• Difficulty establishing;
• Significant changes in the steering system of the vehicle;
• Needs regular maintenance.

The power steering is designed to facilitate the efforts of the driver when directing the steering wheel to the desired position. Using the power steering, the trajectory of the car becomes stable and unambiguous. The power steering is made in such a way that when it fails, the steering wheel remains slightly movable, but significantly heavier. Although they make handling more convenient, most automobile factories release their models without hydraulic power steering. And experienced motorists install power steering on their own. You will learn exactly how to install the amplifier system from this article.

The process of installing a power steering on a VAZ classic.

Installing a power steering on a VAZ 2106 is not particularly heavy and even an inexperienced driver can handle it. Initially, you need to make sure that the hydraulic booster kit is complete and you have all of its parts in stock. The hydraulic booster kit consists of a pump, a pulley, a steering gear, a hydraulic cylinder, as well as a reservoir and hoses for pressure.
Next, we move on to the actual installation. We install the pump bracket directly on the cylinder head, and then we fix the pump. Next, we change the crankshaft pulley so that it fits the pump drive. It must be remembered that the pump drive must pass through the belt, and not through the chain. After that, you should proceed to change the steering gear. At this stage, you need to refine the design a little. To install the gearbox, you need to make holes on the car's shield.

Next, choose a place to install expansion tank. Install the hydraulic cylinder. When installing it, you must follow the special instructions that come with hydraulic booster.

After all these steps, we connect the system together with high pressure hoses. They should not rub against each other and other parts. Pour oil into hydraulic booster and expansion tank, and proceed to pumping the system.
