How is the electric power steering "Kalina" ("VAZ Kalina") arranged?

The electric booster is one of the components of the steering control of the car. Thanks to him in the system, an additional effort is made to turn the wheel. In other words, the electric booster helps to "twist" the steering wheel in the right direction. In fact, this mechanism performs the same functions as the hydraulic booster. Only the latter is more obsolete in design and less reliable, because of what is practically not used in modern cars. In today's article, we'll look at how the electric power steering "Kalina" works and what details it consists of.

This element assumes the availability of the following devices:

• The electric motor;
• Mechanical transmission;
• control systems.

Operating principle

It is worth noting that the electric power steering "Kalina" does not always work. It comes into effect only when the steering wheel is turned, that is, when the steering wheel turns. At the same time, the motor of this electric booster produces the necessary torque, depending on the torque on the steering gear. All these forces are measured by a special sensor that transmits information to the amplifier ECU. The control unit, in turn, calculates the required power for the engine. How much it will be involved depends on the angle of rotation.

On the paddle switch there is another sensor. It measures the angle of rotation of the wheel. He sends the received data, like the torque sensor, to the computer of the amplifier, and he decides what power it is necessary to create an electric motor for the wheel to turn at the right time.

But that is not all. Electric booster "Kalina" has at its disposal a third sensor, which measures the engine speed to obtain feedback to the computer. It is necessary for the control unit to receive correct information about the speed at which the motor rotates and whether there is too fast rotation.

How is the rake connected to the motor of the amplifier?

After the control unit has processed all the information, it sends a signal to the motor. The latter, in turn, transfers its force to the rail via a worm gear and a drive gear. The rack itself can be moved in two ways: from the engine of the amplifier, which is controlled by the unit, and directly from the steering wheel that drives the driver.

Thus, electric booster "Kalina", in contrast to the hydraulic, takes into account a number of factors, after which the electronics "decides" how and when to operate the motor of the amplifier. And the data depend not only on the readings of the three sensors, but also on the speed of the car.

Electric power steering "Lada Kalina": price

To date, this device can be purchased for 12-13 thousand rubles. At the same time, each mechanism is accompanied by a special electric power steering circuit. "Kalina" and spare parts for it are always several times cheaper than imported analogues, so do not be surprised that the electric booster on Toyota will cost several times more.
