Modern cars are equipped with different typestransmissions. It can be automatic with all the known "torque converter bagel", stepless variator, DSG ("Audi" concern), tiptronic and so on. But no matter how improved gearbox, one of the most reliable is considered to be the classic "mechanics". All domestic cars are equipped with this. The exception is the last generation of "Kalina" and "Vesta" in top-end trim levels, where an automatic transmission is installed. VAZ-2114, regardless of the year of production and configuration, was always equipped with "mechanics". Well, let's look at its device, operating principle and operation features.
A manual transmission serves to transfertorque from the engine to the wheels. It is controlled by a special lever (gearshift). VAZ-2114 is equipped with a classic "five-step", as well as the "Priora", "tens" and other cars of domestic production.
The design of the transmission VAZ-2114 assumes the presence of the following elements:
- Gear boxes.
- Shafts. There are several of them. It is primary, secondary and intermediate.
- Transfer of reverse. It consists of an additional gear and shaft.
- The lever of switching of speeds.
- Carter transmission.
- Drain and oil filler hole.
- Stylus and breather.
The gearshift pattern is on the lever.
Algorithm of gears
Thanks to these details, perception andTransmission of torque from the engine flywheel further to the wheels. Each gear has a different number of teeth and a gear ratio. With each subsequent transmission, it decreases.
As for the latter, its gear ratiois 3.53. The rear speed ensures the rotation of the transmission shaft in the opposite direction. To do this, she needs an additional shaft with a separate gear. As a result, the number of pairs of gears changes to an odd one, and the torque changes its direction. Also this transfer is deprived of the synchronizer - it will not turn on at the speed. The gearbox VAZ-2114 has a gear with an equal gear ratio, which is 0.941. This is the fourth speed. Thus, the secondary shaft of the transmission rotates with the same force as the secondary shaft. That is, the angular velocity of rotation of the two elements is the same. Its motorists call it "direct".
The highest torque of the car - onfirst speed. The engine can easily rotate the wheels, but the speed of the car will not exceed 40 kilometers per hour. When this speed is reached, the tachometer needle is usually in the red scale. Therefore, for further movement, it is necessary to switch to a weaker but faster transfer. Then on the third, fourth and so on. All switching must be carried out in sequence. The power of the engine is not enough to confidently disperse the car at 20 kilometers in the third gear. Of course, if it's not a 5-liter V-8.
Operation, repair and maintenance
To exclude the repair of the gearbox VAZ-2114,the manufacturer recommends regular oil change. In general, most mechanical transmissions are unattended. That is, the period for replacing the lubricant is the resource of the gearbox itself. But this concerns imported cars. Concerning "Samara" it can be said that for normal operation of the gears it is necessary to change the oil in the gearbox. VAZ 2114 is no exception. The manufacturer allocates a period of 60 thousand kilometers. It is also recommended to change it after a long period of inactivity. For example, after "wintering" the car in the garage or on the street. Unlike motor, transmission oil has a high viscosity. For the car VAZ-2114 it is 80W-85.
Oil change in manual transmission
To start, you need to prepare the right amountOil and old capacity for "working off". The standard volume for the five-speed boxes is 3.3 liters. The procedure for changing the oil is not difficult, you can do it yourself. It is poured through the dipstick. Preliminary it is recommended to "warm up" the box, so that the oil becomes more liquid (especially in winter). Pre-clean the surface of the drain and fill (as a rule, this is an untwisted dipstick) from dirt. After removing the rubber plug and using a wire, clean the hole itself. We substitute the container for the old oil. It can be made from an unnecessary plastic canister, cutting out its side part with a knife.
How to extend the service life?
To increase the service life of the gearbox,it is necessary not only to regularly change the oil, but also to switch it correctly. Do not pull the gear lever - when moving from the "first" to the "second", stick to small pauses.
So, we found out the device and the principle of operationmechanical transmission of the car VAZ-2114. Generally speaking, the mechanism of "mechanics" is very reliable - it is difficult to break it. But with untimely oil change and aggressive switching, its life is reduced several times.</ p>
