A car is a complex technical device in which all mechanisms are combined and work smoothly. Thanks to him, a person can enjoy a high-quality and comfortable ride.

Basically, the machine uses mechanical and electrical devices. And if the first is more or less clear, then the second should be dealt with in detail.

Generator

There is a common misconception that the heart of a car is a battery. In fact, the main "power plant" is a generator. It serves to process the rotational energy into electricity. Energizing the battery, the generator does not allow it to discharge. Moreover, the charge should always be constant, without power surges.replacement of generator brushes

The generator consists of the following parts:

  • Housing
  • Pulley.
  • Front and back cover.
  • Anchor. Also called a rotor.
  • Rectifier unit.
  • Generator brushes.
  • Stator
  • Rotor bearings.
  • Slip rings.

Generator brushes

This is one of the main elements of the electrical system of the car. Installed on vehicles operating on all types of fuel and energy.generator brushes

intended for the supply and removal of current. For this reason, if the alternator brushes fail, all the voltage in the car will disappear. And without it, it's just a "dead" mechanism. Therefore, these elements are given special attention.

They are made of graphite, which is why they have another name - "coal". Brushes are made with the same characteristics and do not differ from each other. The exceptions are mechanisms that operate in harsh conditions. For example, devices installed in engines with high revolutions are impregnated with special compounds.

External examination and symptoms of failure

  4. Instant discharge and / or poor battery charging.

The presence of at least one of these symptoms indicates that the generator brushes should be inspected and replaced if necessary. On domestically produced vehicles, a performance check is performed without dismantling. Visually inspect the generator by opening the hood lid. In the line of sight will be its winding and two lids, similar to cans. After removing the voltage regulator, it is necessary to estimate the height at which the graphite parts protrude. If it is less than 5 mm, urgent repair is required.

Replacement

The process itself is not difficult. To replace the generator brush "VAZ 2114", you will need the following tool:
