Technical progress does not stand still andconstantly evolving. Every year new technologies appear, allowing engineers to improve or create completely new parts. This also applies to engineering. In Russia, hundreds of thousands of modern cars are sold annually. Each of them contains the latest technology. We will talk about such a small knot as a starter, and find out which starter is better: a gearbox or a regular one.
The first starter used on the car hada number of significant drawbacks. Over time, the design gradually improved and significantly transformed. The starter is a 4-way electric motor, which is necessary for crankshaft rotation when starting the engine. He takes energy from the battery, at times increases the starting current. Due to this, the launch of any internal combustion engine. The principle of the starter for many years has not changed.
Nevertheless, it was constantly improved.design. The mass of the part decreased, the service life increased due to the use of higher quality and new materials, etc. All this led to the fact that the starter was quite strongly transformed and even a new type appeared - the gearbox. That is what we now talk.
The key feature of this device isthat there is no such intermediate node as a reducer. This allows direct transmission from the starter to the crankshaft. Therefore, the device is simpler to manufacture and much easier to repair. Another feature of such a starter is that the electric current supplied to the switch allows you to instantly engage gear and flywheel. This contributes to the fact that the car starts, as the drivers say, with poltychka.
Currently, they are trying to replace suchstarters for reducing. However, on most cars before it was put a classic starter. The principle of operation and the device made this site extremely hardy. Such units almost never fail due to electrical effects, but they are much more often spent on repairs due to low temperatures.
During operation, the internal combustion engine produces enoughlarge amount of energy. It is enough for lights, music, wipers, etc. In general, while driving, the main load goes to the generator. In a static position, the motor does not produce anything, so you need to start it somehow. To do this, and use different types of starters, along with the battery.
Most often, it is the retractor that fails.starter relay. The price of his benefit is available and starts from 500 rubles and ends with several thousand. In addition, the design has a bendix with drive gear and brushes.
This node works as follows:
Naturally, the starter only works when the engine is started, and then turns off. If this does not happen, then one of the mechanisms is faulty.
After the driver inserts into the lockIgnition key and turns it to its working position, the battery receives current to the traction relay. Due to this, the Bendix gear starter engages gears, at the same time, due to the supply of voltage to the electric motor, the circuit closes and the vehicle starts. After the engine revs exceed the revolutions of our starter, it turns off. Turns on only the next time you start the engine. Well, now let's consider the difference between the gear starter and the usual one. There are some interesting details.
The general principle of action is no different.Electrical energy is also converted to mechanical. The only difference is the presence of a gearbox. In addition, there are permanent magnets in the winding in such a starter, which made it possible to somewhat increase the reliability of the electric motor as a whole. Of course, there are some special features. In particular, many are interested in how much this type of starter costs. In most cases, somewhat more expensive than the classic, but not very. On average, 10-15%. But the term of his service is much higher, and it must be taken into account.
Here we are actually gradually approaching the answer to the question of which starter is better: a gearbox or a regular one. To do this, consider the strengths of the classic version. They are as follows:
But there are also its disadvantages, which are expressed in the following:
In general, it is quite reliable designwith proper maintenance. But development does not stand still, and this has led to more advanced gear starters. Consider their strengths and weaknesses.
We have already figured out how this worksdevice and what are its fundamental differences. Already it is easy to guess which starter is better, gear or regular. The fact is that the first option has the following strengths:
As for the cons, they are here and are as follows:
Often the main cause of a starter crash withgearbox is that the installed components of poor quality. This leads to breakdowns and various kinds of malfunctions. In general, such a unit has more prospects in the future than an ordinary starter. And this is not at all due to the fact that one is good and the other is bad, but scientific and technical progress.
If you decide to replace this node, then you needfirst decide where the starter is. Usually this is the driver's side under the engine or on the side of it. To remove it is necessary to free up space. Depending on the location, it may be necessary to dismantle the motor protection or the air filter with the duct. Next, disconnect the wires and unscrew the bolts. Determining where the starter is is easy. It has a cylindrical shape, and from it are several wires fixed by a nut. Everything is done quite simply and quickly.
So we answered the question about which starterbetter: gear or normal. Classic starters are good in their own way, but are gradually being decommissioned. But they also have their own strengths, like the gearbox ones - their weaknesses. For example, in the outback it will be difficult to find parts for a starter with a gearbox, and for a regular one - without problems. The same can be said about the repair - not all faced with the gearbox on the starter and not everyone will take it. How much is a starter with a gear? It all depends on the brand of car, a normal cost of 5-7 thousand rubles.
