Width between the wheels of a VAZ car

It is the VAZ 2101 that is the oldest model of the Volga Automobile Plant, with which the history of the domestic automobile industry began. The model was based on the Fiat 124 of the 1966 model year. In fact, the first “kopecks” were practically Italian cars, because... VAZ 2101 and Fiat 124 were not much different from each other: the share of identical spare parts was 90%.

Creation of VAZ-2101

Everyone knows that the VAZ 2101, or in common parlance “Kopeyka”, copied the external features and technical features from the Italian Fiat-124 model of 1966.
Of course, all materials for production were used only Soviet ones. The first stage of the plant was put into operation on March 24, 1971 and was designed to produce 220,000 cars per year. The following year, AvtoVAZ doubled its production capacity.

The VAZ-2101 was created as a low-power car (four-cylinder engine capacity was 1.2 liters; power - 62 hp at 600 rpm; maximum speed - 140 km/h) and with a relatively low price, so that everyone could afford to buy a legendary car.

Compared to the Italian prototype, the VAZ-2101 acquired rear drum brakes (instead of disc brakes), which were more durable and resistant to dirt. According to the characteristics of our roads, the ground clearance was also increased, the body and suspension were strengthened. In all subsequent years, the VAZ model was refined and subjected to modifications. But even in this (pristine) form, the VAZ-2101 was produced until 1982 and became a truly “people's” car.

Vehicle track width

The term vehicle track refers to the width between wheels located on the same axle. It is calculated from the middle of the tread pattern of the left wheel to the middle of the right. When a car has dual wheels, the width is also calculated from the middle of the footprints of the left and right pairs of wheels. There is another definition of this expression.

In common parlance, a track is the trace a car leaves when it moves. A rut is formed where cars drive one after another, trail after trail. Modern asphalt perfectly demonstrates how deep such ruts can be. Several years ago, at many city intersections and public transport stops, the ruts in the asphalt reached such a depth that you could easily scrape your bottom and fall into one of them.

Every car enthusiast, especially beginners, knows what a winter rut is in their yards, and how difficult it can be to get out of it. But today we are not talking about this track, but about the track of the car.

Characteristics of VAZ 2101

Domestic car designers paid special attention to modifications to the VAZ 2101 for more comfortable operating conditions in our country. As you know, the road surface in Russia is significantly different from Italy, so the body and suspension were significantly strengthened, which improved the technical characteristics of the VAZ 2101. The rear disc brakes from Fiat were replaced with drum ones. This was explained by their durability and resistance to dust and dirt, for which Soviet roadways were famous.

Almost everything has changed, and most importantly, the engine design. Automotive designers increased the distance between the cylinders (this made it possible to bore the diameter of the cylinders) and moved the camshaft to the cylinder head. Changes also affected the clutch, gearbox, and rear suspension. As a result, the weight of the car increased by 90 kg. In total, there were more than 800 changes and differences in the design of the VAZ 2101.

From 1970 to 1986, the plant produced almost three million VAZ 2101 cars. When 19 years passed after the car was released, the AvtoVAZ Museum was replenished with a new attraction - the VAZ-2101.

Why does the car flip over?

It is worth mentioning the advantages a car with a wide track has over its brother with a narrow track. The wider the car's track, the more stable it becomes, and the less susceptible it is to rollover on slopes and steep turns. The higher the center of gravity and the narrower the track, the more likely the car is to roll over. On a slope, it is acted upon by centrifugal force and gravity. The power of slip resistance adds fuel to the fire. An example is shown in the figure below. All these factors together can easily cause the car to overturn.

Of course, sustainability is also influenced by a number of factors, such as:

1. the vehicle’s center of gravity, its weight, base and load;
2. condition of tires and their sizes;
3. the speed at which the car moves down a slope and turns;
4. road condition;
5. driver professionalism, ability to drive a vehicle in extreme situations.

The manufacturer initially carries out all the necessary calculations to ensure that your car is stable. All you have to do is not test it in too extreme conditions. » alt=»»>

Modifications of VAZ-2101

Mass production of VAZ-2101:

VAZ-2101 “Zhiguli” - initial version, 1.2 liter engine. (1970-1983);

VAZ-21011 “Zhiguli-1300” - the so-called “zero eleven” - the main changes occurred in the modification of the body. This car was equipped with an excellent radiator grille with more frequent vertical bars; four additional slots appeared in the lower part of the front panel for better air flow to the radiator of the cooling system. The bumpers lost their “fangs” and were replaced with rubber pads around the perimeter. On the rear pillars of the VAZ-21011, special exhaust ventilation holes for the interior began to be located, which were covered with original grilles; brake lights and turn indicators received reflectors. A reversing light began to be installed on the car (1974-1983). The interior has also undergone changes, which have become more comfortable, as well as ashtrays, for which they found a new place on the door panels. The corrugated silver inserts on the dashboard have given way to woodgrain inserts, and the steering wheel has lost its chrome ring. In addition to this, the modification received a more powerful 69-horsepower engine with a displacement of 1.3 liters.

VAZ-21013 “Lada-1200s” - differs from the VAZ-21011 with a VAZ-2101 engine of lower power (displacement 1.2 l) (1977-1988);

Right-hand drive VAZ-2101:

For export to countries with left-hand traffic, the Volga Automobile Plant has mastered the production of two versions of the Zhiguli - VAZ-21012 and VAZ-21014 (based on the VAZ-2101 and VAZ-21011). They were distinguished by a reinforced suspension spring for the right front wheel, since when the controls were moved to the right side, the distribution of the vehicle’s weight turned out to be uneven. The car was produced during 1974-1982.

Low-volume VAZ-2101:

VAZ-21015 “Karat” is a modification for special services, equipped with an engine.

VAZ-2106, additional gas tank, rear suspension springs from VAZ-2102, points for installing special equipment.

VAZ-21018 - VAZ-311 rotary engine (single-section), 70 hp. With.;

VAZ-21019 - VAZ-411 rotary engine (two-section), 120 hp. With.;

VAZ-2101 pickup - a variant with a pickup body, which had a load capacity of 250-300 kg.

Special VAZ-2101:

VAZ-2101-94 - this modification was a VAZ-2101, equipped with a 1.5 liter engine from the VAZ-2103. The car was primarily intended for the police and special services.

VAZ-21016 is a VAZ-2101 body with a 1.3 liter VAZ-21011 engine.

The export version of the car was called Lada 1200. More than 57,000 cars were sent to the countries of the Socialist Commonwealth. Production of the VAZ-2101 and VAZ-21011 cars was discontinued in 1983, due to increased production of the new VAZ-2105 model. Then they began to produce only a modification of the VAZ-21013, the production of which was completed only in 1988.

Vehicle track

The content of the article:

According to information from Wikipedia, a car track is the distance between the centers of the tracks formed by tires on the road. This is a technically important concept, since the track, along with the clearance and wheelbase, determines the vehicle’s stability, smoothness of movement, brake efficiency, and ability to cope with difficult road sections.

How is the indicator measured?

How to measure the width of the front and rear axles:

• You can do this with a rope (pull it between the middles of the tires, make a mark, then measure).
• Drive through the snow and measure the tracks.
• Align the front wheels, pull 2 ​​threads tangentially along the side wheels. Inspect for the presence of an angle. If there is an angle, then pull the thread from the wider track parallel to the sides, measure the difference on the smaller track.
• Take two slats, insert them into the spacer between the wheels, then pull them out and measure the length with a tape measure. You can take several measurements while moving the car to make sure that uneven rims do not affect the result.

Millimeter precision is not required here, since it does not affect cross-country ability.

Common problems

Throws the car into a rut

A situation often occurs when a car becomes poorly controlled in a rut, the steering wheel rotates on its own, and as a result, the vehicle turns left and right (the car “yaws” or “floats”).

• Use of low profile wide tires.
• Using unidirectional rubber that is installed incorrectly (wrong side).
• Using mixed-width wheels when the wheel sizes on the rear and front axles are different.
• Wheel alignment problems.

The first thing you need to try is to change the tires.

The car catches a rut

The car reacts sharply to any unevenness on the road, constantly sliding into holes, even to the point of knocking out the steering wheel. Driving becomes difficult and stressful, and the accident rate increases.

• Faulty wheel alignment.
• Faulty steering linkage or front struts.
• Inappropriate rubber shape.

Summer tires often have a round cross-section and no tread on the sides. The winter one is softer, with a square cross-section, its contact patch fits well into its track and stays firmly in it.

Why does a car get thrown off track?

When driving along long sections with ruts, the car tries to jump out of it. Because of this, you have to constantly control the steering wheel in the summer, and in the winter, if the car is thrown into the oncoming lane, an accident is possible.

• Tires with developed lateral lugs.
• Over-inflated tires.
• Iron wheels with negative offset.
• Faulty shock absorbers, struts, wheel alignment.

As you can see, the tires chosen for the car influence a lot. To solve the problem, use tire fitting services and purchase tires of a different type and size. Our service “Muffler Master” will professionally perform the work - we invite all residents and guests of St. Petersburg.
