Gearbox ratios for VAZ 2110 table

Transmission tuning. How to choose gear ratios for a gearbox?

Most of the technologies used in transmission tuning are proven in motorsports.
The transmission of any, especially a sports car, is the most important mechanism for realizing the dynamic characteristics of the engine. Even with a relatively weak engine, the car can be fast due to correctly selected gear ratios. In motorsport, synchronized (as on 'road' cars) and non-synchronized (cam) gearboxes are used. Based on the shifting principle, they are divided into conventional (H-pattern) and sequential (with sequential gear selection, like on motorcycles).

In cars of a fairly serious level of preparation, cam gearboxes are used. They have a number of advantages - they can withstand higher loads (due to the shape of the tooth and the gear-cam clutch engagement), allow experienced pilots to spend less time changing gears due to incomplete squeezing of the clutch or without squeezing the clutch at all, they do not destroy synchronizers (which are simply No).

For normal road traffic, cam gearboxes are practically unsuitable, since they are quite noisy (due to the operation of spur gear pairs), “hard” when engaging a gear, and have a relatively short resource. In addition, they are disproportionately more expensive than synchronized ones and require regular qualified maintenance.

Synchronized gearboxes differ from standard ones only in gear ratios. In some cases (VAZ-2108 and -2110) it is possible to add a 6th gear. The correct selection of gear ratios of the main gearbox pair, the input shaft and the driven gears of the secondary shaft is the key to coordinated operation of the transmission. Gear ratios are selected depending on the power and torque characteristics of the engine, wheel size and, most importantly, on the wishes of the car owner.

The gear ratio is the ratio of the number of teeth on the driven gear to the number of teeth on the drive gear. The higher it is, the “shorter” and “more powerful” the transmission is, that is, the engine very quickly turns out the required number of revolutions, the acceleration occurs just as quickly, but there is a need for frequent gear changes. As a result, there is a slight decrease in the maximum speed in this gear.

WHEN INSTALLING:

The main pair is 4.1 - the engine is unloaded, it is easier for the motor to spin the wheels, the dynamics of the car increase, the gears are shortened, the maximum speed drops by ~20 km. per hour (at 160 km/h, tachometer revolutions are 5 thousand), fuel consumption + 1 liter. (due to changes in driving).

The main pair 4.3 is the same as 4.1 + 5 mph. in all gears.

Ch. pair 4.1 or 4.3 + sports series (06, 07 or 08): dynamics (fast acceleration due to the main pair) + long gears, mainly 1st and 2nd spin up to the maximum.

Ch. pairs 4.5 and 4.7: gears are even shorter than 4.1 and 4.3 (maximum speed at 5 thousand tachometer revolutions is 140 km/h), recommended use: when towing and transporting heavy trailers.

Ch. pairs 4.9, 5.1, 5.3 and 5.07: used only on steep slopes and climbs (maximum speed 110-120 mph)

Rows: 011, 012, 018 - installation with standard chapter. a pair of 3.9 for forced engines 1.7, 1.8 and 2.0l.

26th cam row (semi-automatic) - gear shifting is carried out without using the clutch, squeezing the clutch is only necessary when starting and stopping.

6th gear retains maximum speed when using ch. couples and sports. row.

Locker (locking differential):

Worm (screw) - increases the vehicle's off-road capability; when one wheel slips, the second wheel automatically turns on (it also turns on when turning).

Disc (friction) - ensures constant rotation of 2 wheels. (Recommended for use only off-road)

Unacceptable:

Shift into gear with a crunch.
Switch quickly from gear to gear.
It is rude to engage the gears (if the gear does not engage, do not forcefully engage it, but release it again and press the clutch, and repeat its engagement).

If you violate the above instructions, the service life of the gears, and accordingly the gearbox, will sharply decrease!!!

Also, it is highly undesirable to start with slipping. Such systematic driving leads to the collapse of the differential, which breaks the gearbox (the large casing suffers), and the car remains unable to move. BE SURE to check that the clutch is in good condition! The clutch is checked like this:

Correct adjustment of the clutch pedal (pedal at the level of the brake pedal)
Squeeze, pause for 2 seconds, reverse gear should engage without crunching. If the reverse gear engages with a crunch or does not engage at all, then this indicates that the clutch is “driving” and needs to be changed immediately! With such a malfunction, there is a large load on the front gear synchronizers, which leads to their rapid wear and failure.

Disadvantages, breakdowns and problems of the Lada 2110 box

This manual transmission is famous for its low reliability, unclear shifts and howling in operation.

Most complaints about noise and crackling when switching due to wear of synchronizers

In second place are endless oil leaks from various seals, gaskets or breather

Next comes the wear of the plastic bushings in the manual transmission and failure to engage or knock out the gear.

Closer to 100,000 km, gears and bearings are already exhausting their service life

conclusions

The “classical” gear selection algorithm involves determining (strictly) the gear ratio in the highest gear and (not strictly) in the lowest gear. Afterwards, intermediate gears are distributed between these values.

You can start selecting intermediate gears with a uniform distribution with the same q index for all gears. After analyzing the dynamic characteristics constructed for this distribution, you can proceed to correction - small changes in the gearboxes towards bringing them closer together in higher gears.

Overdrive (a gear higher than the one at which maximum speed is achieved, usually fifth) in the classic algorithm is assigned after determining the gear ratio in fourth gear. To do this, you can set a typical indicator q for gears 4-5, analyze the dynamic characteristics and, if necessary, make changes.

Top gear ratio selection

The highest gear should provide acceleration to maximum speed. The maximum speed of a motorcycle can be calculated from engine power using the formula:

Here: – the highest speed of the motorcycle, m/s; – maximum effective engine power, W; – efficiency factor of the motor installation, characterizes losses in the engine, on average = 0.89; – road resistance force, N; – air resistance force at the design speed, N. The transmission ratio in top gear n to ensure maximum speed will be:

Here: – engine speed at highest power, taken from the engine characteristics.

These are the formulas by which the M-72 transmission was designed (or tested). Let's check:

We accept =18.78, with the final gear “eight” with a gear ratio of 4.62, the gear ratio of the first gear of the gearbox is obtained

Gear ratio 1st gear M72 =3.6

Highest (fourth) gear ratio:

Gear ratio 4th gear M72 =1.3

The parameters of the M-72 motorcycle for calculations are taken from the book “Soviet Motorcycles” and the recommendations set out in the article above. The gear ratios for 1st and 4th gears need to be clarified by the number of gear teeth, selecting the closest possible value.
