Overview of the Russian automotive spare parts market. Analysis of the retail brake disc market trends in the automotive component market

Analysis of car brake systems

To the brake control of the car, which serves to slow down the movement, up to a complete stop and holding it in place in the parking lot, there are increased requirements, as the braking control is the most important means of ensuring the active safety of the car. Requirements for brake systems are regulated by GOST 22895-95 and international rules of the road.

Requirements for brake systems are as follows:

The maximum brake path is the maximum setting slowdown in accordance with the requirements of GOST 22895-95, for passenger cars and trucks depending on the type of test.

Preservation of braking stability (sustainability criteria: linear deviation, angular deviation, angle of folding of the road train.)

Stability of brake properties with repeated braking.

The minimum response time of the brake drive.

The power tracking action of the brake drive, that is, the proportionality between the pedal force and the drive moment.

Small brake control work - effort to brake pedals depending on the destination motor vehicle It must be within 500 ....7oo n, the course of the brake pedal is 80 ... 180mm.

Lack of organoft phenomena (auditory).

Reliability of all elements of brake systems, the main elements (brake pedal, main brake cylinder, brake valve, etc.) must have guaranteed strength, should not fail through the guaranteed resource, alarm that notifies the driver of a malfunction should also be provided brake system.

In accordance with GOST 22895-95, the braking control should include the following brake systems:

Workers

spare

parking

Auxiliary (retarder brake), mandatory for buses with a complete mass of over 5 tons and trucks weighing over 12 tons, intended for braking on long-term descents and supporting the speed of 30km / h on the descent with a slope of 7% 6km.

Forced slowdown can be carried out in various ways: mechanical, hydraulic, electric, extracillage.

The most widely used friction brake mechanisms. On the Light Class cars, disc brake mechanisms are often used on the front wheels and drumboards on the rear wheels.

On cargo vehicles, regardless of their carrying capacity, drum shods are installed brake mechanisms. Only in recent years there has been a tendency to use disk mechanisms for trucks.

Drum ribbon brake mechanisms as wheeled currently do not apply at all. In rare cases, they are used as transmission for parking braking system (MAZ, BelAZ-540).

Hydraulic and electric brake mechanisms are used as a brake-retarder. On a number of cars, the retarder brake is the engine, the intake manifold overlaps with a steel flap.

A mechanical drive consisting of thrust and levers is used mainly in the brake systems with manual control (auxiliary brake system - "parking - brake").

In this drive, the muscular energy of the driver is used to turn on the brake mechanism. Simplicity of design and the stiffness of the mechanical drive unchanged in time make it the most used for the parking brake system.

The hydraulic drive is used in the working brake system of passenger cars and cargo small and medium loading capacity. In this drive, the force of the pedal axis to the brake mechanisms is transmitted by liquid. To turn on the brakes, the muscular energy of the driver is used. To ensure the driver's work on the inclusion of brakes, hydraulic drive with vacuum (GAZ-66) or pneumatic amplifier (URAL-4320) is often used.

Currently, the hydraulic drive with the pump is beginning to be obtained. In this case, to include brake mechanisms and the creation required for the quick braking of the braking moments on wheels, the engine is used by the engine drivening hydraulic pump directly, or through any automobile power unit.

Pneumatic drive is widely used in the brake system of tractors, trucks of medium and large lifting capacity and buses. In the brake system with a pneumatic drive, the brake mechanisms are included through the use of compressed air energy.

A combined hydropneumatic drive is often used on long-base cars and tractors of heavy road trains. In this drive, the energy of compressed air is used to increase the brake force, and the transmission to the braking mechanism is carried out by liquid.

Electrical drive is needed on road trains, since the easiest way to transmit energy over long distances is achieved with a very small time on the brake system triggered.

The following criteria are used to assess the design schemes of brake mechanisms:

1)Efficiency

To assess the efficiency of the braking mechanism, its efficiency is served, which is the ratio of the braking moment. M.the torus created by the mechanism, by the time of the primary force:

TOe. = M.tor / ( Rp.S. r.p),

where M.torus -turn moment; P.p.S. - the total driving force of the brake pads; r.p is the radius of the resulting friction force ( r.n \u003d r.b - the radius of the brake brake drum in the drum mechanism; r.n \u003d r.cP - average lining radius in disk mechanism).

The efficacy of brake mechanisms must be assessed when the car is moving both forward and forth.

In the drum brake mechanism, the efficiency coefficient is calculated not only for the mechanism as a whole, but also separately for each brake pad:

where M.tor1 I. M.tor2 - brake moments created by pads; P.1 I. R2 - Drive Power Pads.

2) Stability

Stability is the maintenance of the efficiency of the brake mechanism while reducing the friction coefficient. Stability is the dependence of the efficiency coefficient of friction coefficient and can be expressed by a graph of the static characteristics of the braking mechanism. Best stability have brake mechanisms with a linear static characteristic.

From stability, the achievement of equal brake forces depends not only on the wheels of one bridge, but also on the right and left wheels of the car, which determines the safety when braking.

3) equilibrium

The brake mechanism is balanced, in which when braking the friction force does not create an additional load on wheel bearings and other parts. The braking mechanism, whose work leads to the loading of the car bearings is considered unbalanced.

4) Reversion

Reversible is called equal efficacy of the brake mechanism when moving the car back and forth. The reversibility of the brake mechanism determines the independence of the magnitude of the braking torque created by them from the direction of the vehicle movement.

So far, the drum braking mechanisms are most satisfying the safety requirements of the movement, but due to the increased velocity speeds of the car, the safety safety requirements are also increasing, in many ways of the car braking quality.

Comparative stand tests of various options for the designs of closed disk and drum brake mechanisms for cars revealed that the best indicators for the stability of the output parameters, heat-stability and mass has a disc brake with two surfaces of friction, pneumatic drive and amplifier.

According to constructive execution, disc brake mechanisms are divided into open and closed, one-piece and multi-disc.

Depending on the design of the disk, brake mechanisms with solid and ventilated, metal and bimetallic discs are distinguished.

The solid disk is the simplest - applied in cases if there is an active cooling of the disk brake. The ventilated disc is made in the form of a turbine impeller. In cars, it is mainly one-piece brake mechanisms with a ventilation disk and an internal diameter fastening.

Depending on the method of fastening the brake, discovered disc brake mechanisms with a fixed and floating brake. The brake mechanism with a floating joke has only one wheeled cylinder. His block is heated less than in the mechanism with a fixed bracket, but has a significant drawback - during deformation, corrosion of the guides arises unilateral wear of the lining and the disk. The braking efficiency is reduced, the vibration of the brake and brake pad appears. A fixed screw brake is provided with a large driving force and increased rigidity of the mechanism.

Brake discs are made of cast iron. In one-piece mechanisms, solid discs have a thickness of 8 ... 13 mm, ventilated 16 ... 25 mm. Bimetallic brake disc can be performed with aluminum or copper base. The friction layer is made of gray cast iron.

Disc brake mechanisms have the following advantages compared to drum brakes:

Smaller gaps between discs and pads in the uneasured state (0.005 ... 0.1 mm) and the stroke of the pads, which makes it possible to increase the speed and gear ratio of the brake drive;

Lower weight and dimensions:

More uniform wear of friction materials, as it is distributed uniformly pressure on the surface of the friction pair disk - the shoe:

Larger braking moment, developed by balancing forces acting on the side of the pads on the disk;

The possibility of ensuring an effective heat sink from rubbing elements;

Greater stability of the developed brake moment;

Larger brake efficiency coefficient;

The disadvantages of disk brake mechanisms include:

The difficulty of ensuring sealing (unprotected disk can be subjected to abrasive effects, oxidation and corrosion, promoting rapid wear of the brake linings);

Increased intensity of wear of friction linings;

Insufficient protectedness from dirt;

Conducted road-laboratory tests of drum and disc brakes Kharkov Adi have shown that in the case of heating the brake parts up to 300 ° C and V \u003d 40 km / h, the braking path increases during braking by disk brakes by 7%, and drums by 25%. If the normal speed is the same, but the volumetric temperature will reach 500c, the braking path will increase by 21% and 55%, respectively.

The main task of the car brake system is to reduce to a minimum of the brake path and the preservation of the stability and control of the car.

The maximum load on the system occurs in emergency braking mode. Perfect braking is possible only when the clutch forces are fully used with expensive, but without blocking the wheels.

The first assistant driver when braking was the regulator distributing the pressure in the brake contours of the front and rear wheels. The main factor determining the need to regulate the magnitude of the braking moments is the wide variation of the tire clutch coefficient with an expensive.

The perfect regulator must ensure the execution of two functions:

1. Always establish the optimal pressure ratio in the contours of the front and rear brakes;

2. In case of emergency braking, maintain pressure in the contours of the front and rear brakes at the level that ensures the full implementation of the clutch forces throughout the entire phase of the steady deceleration.

The implementation of the first function provides the greatest stock of the stability and controllability of the car and the simultaneity of the wheel supply to the clutch limit. The implementation of the second provides the minimum braking path. Unfortunately, the creation of an ideal regulator is an extremely complex task and costly. Therefore, in practice, regulators have been used in practice, which only partially solve the specified tasks. The regulators used can be divided into two groups: regulators without feedback and feedback regulators.

The use of brake force regulators significantly increases the efficiency of emergency braking of the car. However, the performance characteristics of both static and dynamic regulators are still far from optimal. The main disadvantage of existing regulators is that in case of emergency braking, they do not exclude both the pretreatment of the wheels (as a rule, the rear axle) and their overhauls (as a rule, the wheels of the front axle). This is due to the fact that the regulators discussed above do not track the actual rolling mode of the wheel and do not provide the optimal selection of limit pressure in the drive of the front and rear wheels.

As a result, there is an incomplete use of clutch forces and blocking wheels. Especially significant, the second drawback, because Blocking the transition of wheels in the South Kazakhstan causes two negative consequences:

1. Reducing the longitudinal clutch of tires with a canvas (especially significant on slippery roads);

2. The fall of the ability to perceive lateral forces.

At the same time, the decrease in the clutch coefficient φ x causes an increase in the length of the braking path, and the loss of the ability to perceive the transverse reactions - the loss of car manageability (with the front of the front wheels) or the drift (in the yose of the rear wheels).

The decrease in φ x when moving wheels to the SOZ is explained by changing the nature of the interaction of tires with a support surface. On dry asphalt roads, the decrease in the clutch forces relatively little, but on slippery roads the drop φ x can reach 50% compared to what is implemented with optimal mode of slipping wheels.

If the slippages increase, the transverse reaction coefficient drops sharply, i.e. Wheels lose the ability to perceive lateral efforts.

Thus, the transition of wheels into the locked state is extremely undesirable, because There is a decline in both the efficiency and safety of emergency braking of the car. This gave impetus to the development and practical use of such regulators that protect the wheels from blocking and maintain the pressure in the drive, providing 15% ... 30% slipping of the wheels. Such automatic regulators received the name of anti-lock systems (ABS), or anti-locking devices (ABU).

The ABS according to the principle of regulation can be divided into three main groups:

1. with individual regulation of each wheel (individual regulizung) -ir;

2. With "low-level adjustment", i.e. simultaneously regulating both wheels on the wheel sensor signals in the worst clutch conditions (SELECT Low) -SL;

3. With "high-speed regulation", i.e. Simultaneous control of the wheels of one axis across the wheel sensor signal located in the best clutch conditions (SELECT HIGH) -sh.

ABS can be implemented on a different element database and are made by significantly different from each other. basic schemes. At the same time, the common tasks and object of regulation causes the presence in the system under consideration functional structures and nodes serving similar purposes. To such structures, first of all, the actuator with a drive acting directly regulating the braking torch; The status sensors of the functional systems of the car, which control the change in a parameter, and the control unit based on the incoming information.

For the optimal combination of the efficiency of braking and stability of the car, feedback systems are needed.

Marketing report

"The market of automotive components

and spare parts in Russia "

In the first half of 2010, the Analytical Agency "Avtostat" prepared the marketing report "The market of automotive components and spare parts in Russia". In addition to collecting and processing information, analysts have developed their own approach to assessing the capacity of the market. Moreover, in the current report, according to the results of 2009, the technique was seriously improved in order to obtain more detailed data. For which the entire park was broken not only on domestic and imported brands, but also for four age groups.

The calculation of the capacity was made in all the main segments of the secondary market after evaluating the resource of spare parts. In total, there were calculated dozens of positions of spare parts, which were divided into 18 groups. The final calculations are presented in the report in physical terms (pieces or sets) and money (USD) for each position , by groups of spare parts and in general, the market for 4 years , including the forecast for 2010. Please note that the calculations were conducted on the component and spare parts market. only for passenger cars.

The report was prepared by the Cabinet Research method. The main sources of information are their own databases and information obtained directly in market participating companies. The structure of information feed and settlement techniques are developed by specialists of the Avtostat Analytical Agency. Nevertheless, they are all based on the fundamental principles of calculating the capacity of the market accepted in United States.

■ Stages of the formation of the car component market in Russia

The autocomponent market in Russia, like the entire automotive industry as a whole, was the path of development, differing from the path to which this market developed in Western Europe. Its main feature is to exist for a long time in the conditions of a planned economy.

Most of the components for the assembly during this period were produced either on themselves automotive plantsOr in enterprises producing a very wide range of products of a particular profile, such as electrical engineering or rubber-nucleicizing.

During the transition of the country to the market economy, the development and market of autocomponents was developed. First of all, this trend touched the secondary market, that is, parts and components intended for maintenance and repair of cars. Enterprises that had technological capabilities and production facilities established the production of components for the secondary market.

With the further growth of the automotive market in Russia and the adoption by the Government of the Decree "On Industrial Assembly" No. 000, enterprises for the production of foreign cars are opened in the country.

we are on the threshold of a new phase of industry development. In April 2010, a strategy for the development of the Russian auto industry was approved for the period up to 2020, which determined possible scenarios for the development of both automotive production and component industries.

■ Section I. General Characteristics of the Market, Trends and Prospects

In 2009 in the territory Russian Federation About 595 thousand passenger cars were collected, which is almost 60% less than the previous year. Including the assembly of car foreign brands amounted to just under 279 thousand cars (53% fall in relation to 2008). Nomny more seriously collapsed the program for the production of passenger cars of domestic brands - 316.9 thousand units were collected in quantitative terms against 879.1 a year earlier.

The largest manufacturer of passenger cars in Russia in 2009 remained AvtoVAZ: an enterprise produced 294.7 thousand cars (63.2%). If we consider that the total assembly of passenger cars in the country did not exceed 600 thousand pieces, it becomes obvious: the Togliatti brand has a significant position in the automotive industry of the Russian Federation.

In 2009, more than 1 million 396 thousand new passenger cars were sold in Russia. The fraction of foreign cars has decreased and amounted to 72.9% (1.01 million pcs.). Domestic models have slightly strengthened their positions - their share increased by 2.5 percent to 27.1%. The market leader still remains the production of LADA brand, whose sales amounted to a little more than 354 thousand pcs. And a market share - 25.3%. On other Russian stamps every year there are an excellent part of the market. passenger cars: According to the results of 2009, this figure amounted to 1.7%.

The leader among foreign cars remains Chevrolet with the result of 104.4 thousand pieces, it owns about 7.5% of the Russian market for new cars. The success of the brand in the country is due to the popularity of cheap Ukrainian models Chevrolet Lanos., Models of the Korean division of Chevrolet Dat (Chevrolet Lacetti and Aveo) and products of the JV "GM-AvtoVAZ" (Chevrolet Niva). N.

Regional Park Structure

As of the beginning of 2010, the Russian park has numbered 32.8 million cars, which relate to the category of passenger. Note that this amount did not get models that relate to the segment "Light commercial equipment"(LCV) (for example, IL-2717, Peugeot Partner or Volkswagen Transporter), which belong to the category" B "and taken into account in the previous report.

Analyzing the margin structure of the park, it can be noted that the total share of cars russian marks steadily declining. Nevertheless, they account for about 60% of the country's park. Still most of the park (43.5%) account for Togliatti stamps Lada..

parka. The number of foreign cars in oSSia from year to year is growing steadily. Focusing on the structure of the park as of the beginning of 2010, it can be stated that more than 40 percent of passenger cars operated in Russia are foreign label on the body. The total number of foreign cars by 2010 increased to 13.3 million units.

The leading position in a foreign park occupies Japanese Toyota (2.8 million pieces), which accounts for 8.6% of the Russian Park.

Market structure and classification of participants

The production industry of automotive components and spare parts in our country began to form in parallel with the development of the auto industry.

Historically, it happened that most of the components produced by the automakers themselves. In addition, enterprises produced in the industry were involved wide gamma Products for different sectors of the economy, including for the automotive industry. At the same time, in the conditions of a planned economy, there was a clear distribution - who, who and what should be supplied.

In the early 1990s, after the collapse of the USSR, market mechanisms of interaction between enterprises began to be formed. Partposter who remained outside of Russia or not withstanding market competition were forced to reduce the volume of supply or to go away from the market. They began to replace new players, more mobile and technologically "advanced".

At the same time, a number of enterprises of the autocomp-negotiated sector were born due to the process of "removal" of individual pro-devices outside of the assembly plants that began in the mid-1990s.

The concept of the development of the auto industry until 2020, developed by the Ministry of Industry, and approved by the Government of Russia at the end of April 2010, provides for a significant upgrade of the autocomponent sector. It is assumed that over the next 10 years, about 150 billion rubles will be invested in this direction.

The restructuring of the landscape of Russian suppliers of autocomponents on horizontal specialization involves their consolidation and specialization in the categories of autocomponents with supply for several automakers. At the same time, it is planned that in each category of auto components there will be 2 - 3 manufacturers competing with each other.

Distinctive features of the Russian market

The Russian automotive component market and spare parts have a number of distinctive features from European or American. These features are associated with the history of the formation of the market, geography and climate of the country, as well as with the mentality of market participants. The poverty of a large number of real and potential consumers plays the poverty of a large number of real and potential consumers here, but at the same time, a great desire to have its own vehicle.

Although the share of foreign cars in the Russian park is gradually increasing, there are still quite a few old Russian models in operation. For example, the share of VAZ "Classics" in the Russian park of cars is 22.3%, the share of "Muscovites" - 4.4%, Volga - 4.8%, "ZAZ" - 2.6%, "UAZ OV "- 1.6%.

Trends and prospects for the car component market

According to the results of 2009, the total production of automotive equipment in oSsea decreased by 59.8% and amounted to 722.4 thousand units. This is the lowest car production digit over the past 38 years. In 2010, the market begins to recover, and most of the assembly enterprises will show the growth of production by an amount of at least 15 percent.

The fundamental document for the development of both the automotive industry and the component industry today is the "Strategy for the Development of the Automotive Industry of the Russian Federation for the period up to 2020", approved by the Order of the Ministry of Industry and Commission No. 000 dated 01.01.01. One of the strategy blocks is assigned to the definition of development scenarios for the segment of manufacturers of autocomponents.

As part of the development of the partnership scenario, the following projects of the component industry should be implemented: projects for the production of differentials, shrines, supports, thrust, hinges, suspension modules, ABS systems, brake mechanisms, steering systems, systems passive security, frames and components of seats, generators and starters, electromechanical drives, switches and instruments, door panels, climatic systems, cooling systems, electronic control systems, exhaust systems, precision e / welded pipes, etc.

Localization of the assembly of foreign cars in Russia

At the enterprises of industrial assembly by 2012, as planned, 1.4 million cars can be collected. The industrial regime involves the conclusion of automakers agreements with the Ministry of Economic Development for a period of seven years for existing enterprises and for eight years - for newly created. This agreement is approved by the list of components imported duty free or at a minimum rate from 3 to 5% (instead of 5 - 20%), and localization schedule.

■ Section II. Estimation of the capacity of the market of autocomponents and spare parts in Russia

Method of calculation and basic parameters

The method of calculating the capacity of the secondary market components and spare parts is based on two basic parameters: the operational resource of parts and the serviced car fleet.

All the park we broke into four age groups. The first group "up to 3 years" combines cars, in the overwhelming majority on the warranty service at the dealer. In the second group at the age of 3-10 years, cars were included in which the guarantee ended, but the technical condition remains good, and serious repair costs appear closer to the end of the period. A large risk of refusing to many knots in cars in an emergency. N u and most of all the time in repair is carried out by car owners older than 20 years.

Each age group corresponds to its average annual mileage: for cars up to three years - 20 thousand km, from 3 to 10 years - 18 thousand km, from 10 to 20 years - 15 thousand km and cars older than 20 years - 10 thousand km .

Characteristics and assessment of the capacity of the secondary market

According to our assessment, the total amount of the secondary car component market and spare parts in Osia in 2009 amounted to over 15 billion USD. This figure is smaller than the number of the previous year due to the increased dollar rate, because during the calculations we operated on the ruble cost with the subsequent recalculation of the result in dollars. In our forecast, the growth of the market capacity in monetary terms will occur this year by a value of 19.5%. The reasons are two: the growth of the park and the increase in ruble prices for parts observed in the first half of 2010. This happens against the background of the dollar, the level of which is similar to last year's.

In this report, we looked at only a few dozen of the most running positions, dividing them into 18 commodity groups. Their composition includes basic parts that require regular replacement and whose failure is not a single case and consequences of marriage or improper operation.

Each group of components is given to a separate page, which presents a brief description of the market for this component, market structure, market capacity by year and the calculated capacity of the secondary market in accordance with the age structure of the park.

Groups presented in the report: Car tires; batteries; facial body parts; Exterior details. Automotive oils and lubricants; filters; Details of the brake system. Nodes and details: suspension; steering; clutch; transmissions; fuel system; release systems; ignition systems; systems; Esud; electrical equipment. Details for motor overhaul; Drive belts. As an example, data from the page on one of the groups.

Car batteries

Russian market of batteries for cars in 2009 survived not best timesAnd most of all, the positions of the primary market were shaken: all car manufacturers significantly reduced the production program.

According to our estimates of the secondary market based on the average resource rechargeable battery At 4 years old (it is so much a battery is served with proper care and non-rigid operating modes), and an active fleet of 26.8 million cars, the annual need of Russian car owners in batteries is estimated at 5.8 million units.

This figure can fluctuate in a rather wide range - the strong dependence of the ACB resource from climatic operating conditions is affected. H Abstractly cold winter generates a surge in sales of batteries, and warm winter can extend its service life for 2 to 3 years.

■ Section III Characteristics of Spare Parts Sellers

Spare parts for passenger cars on the Russian market are delivered to more than a hundred specialized companies. We did not set the task of the full coverage of this market segment, the companies presented are the largest players in different regions of Russia. The report presents short description 58 companies - spare parts sellers.

■ Section IV Characteristics of manufacturers of automotive components and spare parts (profiles)

This section presents profiles of manufacturers of automotive components, including 46 profiles of foreign manufacturers present in the Russian market and 272 profiles of Russian autocomponent manufacturers.

Each profile contains a brief description of the company's activities, in the world and in Russia (for foreign), the details of the head company and representative offices in Russia (for foreign companies), information on the head, financial indicators and the indication of the main activity.

The brake disc market segment has been actively expanding recently. This is due to the increase in car park and with an increase in the number of machines that are equipped with disk brakes on both axes. Unfortunately, the decline in control over the passage of technical inspection has negatively affected the secondary brake disc market. Many motorists exploit cars with worn discs even when it is uncomfortable and unsafe.

Information is collected by the Marketing Department of our magazine.

However, despite this, Vladvysservis, another in 2011, evaluated the capacity of the Russian brake disc market in more than 10 million per year. At the same time, the market, according to experts of this company, is divided by approximately half: 5.2 million brake disc units are in demand in the car segment foreign production And about 5.1 million units - in the segment of Russian cars. Obviously, over the past two years, its capacity has increased, but the editorial board does not have more recent data.

It should be noted that recently (second half of 2013 - the beginning of 2014) there is a decrease in sales of new cars. If this trend is long, then brake disc sellers (however, both other automotive components) may encounter sales of sales volumes and even with a decrease in demand. In order not to face this situation, it is necessary to begin active work today about the increase in the culture of servicing this assembly and the braking system as a whole with consumers who go to the services, after all, sales of disks occur mainly on car services. The cost of this component is quite high, so before deciding on the replacement, the car owner must make sure that it is possible to make it further operation, and this can be done only according to the results of diagnosis on the brake stand and visual inspection Auto mechanic. Self-diagnosis is usually ineffective.

The resource of the modern brake disc is about 80,000 - 100,000 mileage kilometers (this is in ideal conditions). In Russia, due to the presence of low-quality brake pads and very heavy Conditions operation, the service life of the disk is often ends much earlier. The use of cheap pads, as well as the habit of changing them only after complete wear, lead to the formation of grooves (deep wipes) on the working surface of the disk. In some cases, this problem is eliminated after the disk groove if the problem is not too late and the thickness of the disk allows you to perform this procedure.

Lack of quality service brake calipers (Lubrication and cleaning with each change of brake pads) leads to the fact that the pads are not fully returned to their position after the driver releases the brake pedal. It leads to accelerated wear disk.

High risks for the status of the disk create Russian road conditions, namely, a large number of puddle on the roads. Sudden wheels in the puddle creates a danger of sharp discharge of the disc, which over time leads to the formation of cracks.

As for the rear brake discs, which today are increasingly found on foreign cars, the surface corrosion of the surface is the greatest danger. Brake discs rear wheels with a non-aggressive ride manner work in a gentle mode. If at the same time and the car is not used frequently, the rear wheels can be covered with rust, which is subsequently peeled, and the disc is wearing unevenly.

Maintenance stations managers need to talk about these risks to their customers. This will allow, on the one hand, extend the average service life of the brake discs, on the other hand, increase the number of sales, or service operations that are related to the service of this node, since timely maintenance of the disk, pads and caliper, as a rule, avoid early replacement. So the service station from holding such a policy in any case will be in winning, because it will be able to earn either on replacing or on service.

The objectives of our study is to assess the share of presence in the retail segment of the main braking brakes of brake discs, as well as a comparison of the average retail prices for this product. According to the tradition, the study was conducted on three most massive models of cars, which were long presented on the Russian market and spare parts for which in Russian secondary market. This is a VAZ 2110, Renault Logan and Ford Focus II.

Lada

For competitive, this market segment is one of the most difficult. The market contains 20 brake brakes brake discs for VAZ. At the same time, the highest shares of the presence in the retail market (diabetes 1) has one of the largest importers companies of this product (Brembo) - it is represented by 14% of the outlets, and in second place there is one of the leading Russian stamps - Autoal (8%). In general, differences in the representation of brands in this segment are minimal. A decade of a total frontier overcame only one company (Brembo). The overwhelming majority of all other participants are presented in a very small number of outlets - from 8 to 4%. When estimating the average prices in the Russian market on this product, we were forced to use the cost of a set of front brake discs on the VAZ 2110 for the wheels with a diameter of 14 inches. The choice in favor of a set of two disks is due to the fact that it is in such a packaging that this product is most often found on the market more than half of the suppliers. As for the companies that do not supply brake discs in this packaging, we were forced to take the cost of their single disk and multiply it into two, although this approach is not entirely correct. In the upper price segment (dia.2) there are two brands - ATE and Zimmerman. The cost of a set of such disks exceeds 3000 rubles. In the average price category (from 2000 to 2700 rubles) there are sets of other brands - Brembo, Alnas, TRW, Tornado, Toro, A.B.S., Pilenga.

The most massive price segment is the lower average. A set of such discs from two pieces will cost the consumer in the amount of 1000 to 2000 rubles. It is noteworthy that in this price segment we see by no means newcomers, but well-known brands of auto parts (Valeo, Bosch, Alied Nippon, Trialli, Autoal and others).

Renault Logan.

This market segment is also very saturated. Our experts counted 18 brake brake brakes on this carpresented in the Russian retail market. However, in contrast to the segment of Russian cars Lada, here we see a clear leader - these are TRW discs. They are presented in every fourth retail store from those involved in our survey. According to the representation of TRW, overtakes the original brake discs and the products of the Bosch brand, which is represented in 15% of the outlets. All other suppliers are located below a 10% barrier. In this segment there are several new names that were not in the VAZ segment, there is no point in the segment - everything can be seen in the chart 3.

Now look at price policies suppliers. It is strongly distinguished against the background of all independent brands OEM products. Original brake discs on Renault Logan cost more than all other competitors twice. The most expensive discs from the independent trademark segment are supplied by Textar, Zimmerman and Valeo. They constitute an average price group. All other disks are located in the segment below average. Note that, in contrast to the previous segment in this diagram (№4), we compared prices not to the brake discs from two pieces, and the cost of a single disk.

Ford Focus

In this segment, competition is not so pronounced. No longer 20, and 14 trademarks are struggling for the attention of the Russian consumer (Diaz.5). The main leader on representation in this segment is Brembo. Discs of this brand achieved the same success as TRW in the previous segment. Almost every fourth store (23%) you can buy Brembo discs for Ford Focus. In addition, a decade-percent representation barrier overcame the original brake discs, as well as products of such trademarks as Bosch and TRW. Thus, in almost all segments, we see the same pool of popular brands with one amendment that in the Lada segment in this pool also included trading stamps of Russian factories.

Ford Focus brake disc prices are not as big as in the Renault Logan segment. The cost of the original disks was practically equal to the price of independent brands from the top price segment (TRW, Textar). The price difference between the most expensive and cheapest brake discs on the front axle Ford Focus II is 1000 rubles.

Expert comments:

Sergey Ferkov, marketing ManagertRW AUTOMOTIVE:

- annually a company Trw. produces 12 million brake discs. Assortment of brake discs Company Trw. There are about 1,200 articles - it covers 98% of the car park. Along with the supply of spare parts for the independent car market, we supply brake discs on the assembly conveyors of world automakers. Always being ahead in the field of development, we will not terminate the development of the most modern technologies for the production of brake discs. Thanks to this, our products division for after-sales service can offer the consumer the most relevant products.

Distinctive features of TRW brake discswhich are competitive advantages of our products:

. Coloring non-working surface in blackThat allows you to protect it from corrosion. Previously, the brake discs were treated with a special composition against corrosion, and during installation, the services were to clean the braking disc with the solvent. Many did not do this, because it was required extra time. With painted TRW discs, time is saved when installing.

. In the manufacture of disks, high carbon steel is usedWhat provides them with the highest strength and efficiency.

. All 100% TRW brake discs are balanced at the factorythat eliminates the batting of the discs during operation.

Thanks to these advantages and provided proper Installation The disk of its guaranteed operation is comparable to two deadlines for the operation of the brake pads. That is, the brake disc is recommended to be changed at least than through one shift of the brake pads by car. If you follow this rule, then your car will always be safe for both you and others.

Cyril Sickness, marketing directortrialli:

- Brake discs can be attributed to the category of consumables. Of course, unlike brake pads and filters that require replacement during the passage of annual, brake discs must be changed every two to three years - depending on their wear resistance and the style of driving a particular car owner. Features of demand for brake discs In the realities of the Russian car market of autocomponents directly depend on the number of cars of various brands and models. So far, models of brake disc models for VAZ cars are used, but the tendency of the demand displacement towards parts for foreign-made cars is already noticeable, and every year this demand increases.
