 VAZ
- 2120 VAZ - 2120 «Nadezhda» - seat four-wheel drive minivan, prepared for experimental-industrial production of OJSC «AVTOVAZ» from 1998 to 2006. VAZ 2120 became the first минивэном in the history of the Russian automotive industry. Specially for it was developed-wheel extended platform on the basis of the car «Niva», which was also used for the production model VAZ-2131, so how could stand on itself and the weighted five-door hatchback body. Full-power chassis allowed easy to solve the problem развесовки for the improvement of the road, that in conditions of Russian roads became an important competitive advantage of the vehicle, designed primarily for use as a family. VAZ 2120 мелкосерийно produced in experimental-industrial production (OPP AVTOVAZ). In total for 8 years was collected slightly more than 8000 vehicles. In August of 2006 the production of minivan was stopped due to low demand, stemming from the morally obsolete design and poor correlation «price/quality» in comparison with the пятидверной Niva (VAZ 2131) and the import analogues. History of creation By 1989, the vases were and tested in the design Manager's Department minivans Nissan Prairie and Renault Espace. The idea of production of VAZ однообъемного of the body on all-wheel drive chassis invited the head of the Department of the interior UDA Kuznetsov. The initial sketch was made designer О.Шапкиным. First car was positioned as the modernization of the «Niva». However, after one of the техсоветов in 1989, dedicated to the issues of modernization of VAZ-2121, at which was presented the initial draft of minivan, Kuznetsov was invited to continue this work as the head of the working group, but no longer as at the modernization, and how exactly as above минивэном on the basis of «Niva». The future «Nadezhda» was given to the index of «2114» (the index subsequently transferred to one of the vehicles of the «Samara», and minivan has received the designation «2120»). The first Russian all-wheel-seat minivan "Nadezhda" was carried out in the Experimental-Industrial Production of STC VAZ since 1999 on a platform of a long "Niva" VAZ-2131. Has original suspension single-bin cut-body with a sliding rear right door that provides convenience when boarding and disembarkation of passengers. The size of the VAZ-2120 is one of the largest in the range of VAZ cars. Track front and rear wheels - as in "Cornfields", but the wheelbase extended by half a meter. Length of the machine reaches 4.3 m , that allows you to put in the cabin of three rows of seats, on which sit seven people. The backrests of the second and third row met folding to transform the passenger compartment of семиместного to double cargo-and-passenger version, or, for example, a sleeping place. Car 2120 is convenient for the active family vacations, long-distance travel and use as the official vehicle for small firms. It combines traction, ride comfort and comfort for passengers. After the approval of this project from the foam was the first model in the scale of 1:1, painted on the technology of Biba. The design was recognized as the original, but a few futuristic and so unusual, so in 1990 on the project О.Шапкина was executed the next version of a minivan, a more moderate, which, however, still not been adopted. And only the layout of 1991, served for the future «2120» a kind of a pass on the conveyor. To avoid разунификации the nodes with the base model and thus the opportunity to have as much as possible of the low cost price of a new car, a decision was taken not to create моноприводный minivan, leaving no change «нивовский» full drive (without changes of VAZ-2129 and VAZ 2131). The layout of the engine compartment on the whole was left the same as the VAZ-21213, but the front has been redesigned - were strengthened mud flaps, mounting brackets engine made more stringent. In addition, there were made more stringent amplifiers front side members, front pillars side of the front of the floor, boxes воздухопритока. Was reinforced area of the rear arches and connecting the rear arches under the floor. The body of the vehicle was immediately decided to make a четырехдверным - two front doors, one rear side sliding on the starboard side (there were prototypes and with a swing of the rear right door) and the boot lid. From a swing back door refused because of the dimensions of the door. Sliding side door on the VAZ was applied for the first time, and it was a risk, which, however, was justified (such a decision could not be anywhere try except only for small-scale car - standard vehicles with sliding side door of our industry at that time not yet been issued). The decision of the body turned to be rather hard, it was the stiff body of developed at the WHA to that time. Separately it is necessary to tell about the lighting equipment, as it involves just two incidents significantly influenced the final appearance of the machine. The project minivan was originally for the plant as if «optional» - the plant did not have free capacity to produce it. Moreover, a large body has not been in any of the existing spray booths. Get - well, let's find a way and where to learn (by the way, is a variant of production of VAZ 2120 in Izhevsk), and not - too well, because the designers will have an excellent experience. That is why attention to the project were a few scattered and weakened. His contribution was made by the use of serial lighting equipment, which are subject to strict international rules (including their installation).At first it was planned to equip the minivan original headlights of head light, but in the end, decided to abandon this idea, since the release of cars is not planned large, and the costs for their development in production, certification, etc. promised to be large. Was also rejected the option of the headlights from the VAZ-2110, since the beginning of the issue of minivan was planned much earlier development of production of VAZ-2110 and lights could not be prepared. As a result, in the development of the initial design of a prototype was not considered a promising rule, requiring the presence of гидрокорректора headlights. Therefore, in the initial design were laid lights VAZ-2106 diameter 145 mm. When the project has acquired the status of an official, highlighted the need for this requirement. Of production of headlamps could come only the lights from the «Niva» with the diameter of 180 mm. Accommodation such a big lights in an inclined front of stylistically and structurally, turned out to be very is not a simple task and would require serious changes in the external appearance of the machine. The search for an acceptable solution lay for a long time. In the end, it was applied the scheme with a combined arrangement of the headlights - inside were small-beam, and on the edges of the headlamps from the «Niva». Originally lights were slightly recessed in the chassis (approximately 50), but in a series for reasons of aesthetics went to the option with the forward headlamps, and that was the transition from the headlights to the hood, the original plastic lining on the headlights. Such a pronounced emphasis on the lighting equipment was not the most aesthetically acceptable solution - more forced in the absence of any headlamp at the time. Rear lights were installed from the VAZ-1111. Borrowed from «Oka» rear lights had to be integrated into the surface of the body, or rather the surface of the tailgate exterior of a priori given surface borrowed light. Not taking into account the horizontal optical axis of the back lamp, designers shook it back thereby making the back of the car more vertical. Only 5 degrees, but it is out of tolerance, and therefore a violation of the rules. The mistake became clear only after the beginning of design works. And again needed to urgently correct layout, плаз the surface of, the ongoing work of the layout of nodes tailgate exterior. Needless to say, the reversal of the rear wall of the body greatly changed the appearance of mini - these 5 degrees in the area of the rear lights turned centimeters in the area of the roof. The roof was a shorter, on a side of the body of the acquired an undesirable form, strongly expressed trapeze. As a result of this «the doomsday» car and bought his unprepossessing appearance. Common phrase «made from the lantern» suddenly acquired material meaning. It should be separately mentioned mounting the spare tire. It is located under the vehicle, close to the seat front passenger's on the starboard side. At the same time to reach it, you must first loosen the hook mounting lattice, driving wheel to the bottom of the car, which can only be done from the passenger compartment (nut is located between the front passenger seat and the middle bar of the body). The average number of seats of «Hope» has the opportunity to longitudinal adjustment. Back row is made folding, which allowed to increase the capacity of the Luggage compartment from 0.3 to 0.5 cubic meters, while the average number of seats could also be difficult, that allow us to achieve a flat cargo floor, convenient for transportation of large-sized cargoes. The instrument panel has been developed an original, although considered the application of one of the serial. on October 23, 1995, the officer of STC VAZ, was presented the first prototype of VAZ 2120, later received the name of their own «Nadezhda». From the Department of General layout of the work on the car she was in charge of the group Н.Тазтдинова. Leading the linker was Э.Чмелев. It is noteworthy, but the lead designer on the body was not. The doors of the car were Г.Богданов and А.Кузьмин, the bonnet - Н.Пронин. Bumpers were В.Михалев, Л.Аганин and С.Горбатов; tailgate - И.Силявин and С.Добров; floor - В.Черненко and В.Хохленков; group roof - В.Лихачев; mud flaps, front grille and front did Н.Вершинников. on January 31, 1997 was the first technical presentation of VAZ 2120 and in the same year the car was exhibited in the Moscow international motor show MIMS-97. Since August 1998, in the OPP VAZ began regular мелкосерийный production of VAZ 2120 «Hope», which lasted until the fall of 2002, when the first «Nadezhda» has yielded place on the conveyor Technical parameters The weight of the car with a full load of 2 tons. Towing a trailer is not provided, the machine itself is too heavy. And here is the towing eyelet is located ... in the "trunk" next to the tool. It in case of necessity can be put in special holes on the left or to the right in the front and rear of the vehicle. The left part of the floor is wholly devoted to the large fuel tank - its capacity is not less than 70 liters. The tool kit and Jack are in the niche under the floor in the room (access through the opening tailgate), and under the lateral lids there is a place for little things, the necessary driver. By the way, through the same cover is opened to access the bulbs rear lights. Unusually is located tilt wheel - under the floor in the area of right-wing doors. The instrument panel of the original, but, of course, with the use of VAZ of buttons and keys, but the combination of instruments is borrowed from the "tens". Heater on the "top twenty" is used of "Samara-2", but, in addition to him, there is an additional, in "the left side" near the middle seats. It is necessary to heat the passenger in the middle and the back ranks. In the roof over the front seats carved hatch, but on request we can add and second, in the rear compartment. Such equipment is provided not by chance: the rear Windows do not open, so without a second hatch in the heat do not. The machine is equipped with гидоусилителем the steering wheel.Brake system copied from вазовского SUV: hydraulic dual-circuit drive with vacuum and pressure regulator rear brakes. Brakes front-wheel - disc brakes, rear - drum. "Ruchnik" - rope driven to pad rear brakes. Нивовское and steering control : steering gear worm - roller, pendulum lever, one transverse and two lateral traction. As you can see, the creators of 2120 in respect of the engine, transmission and chassis maximum use of the opportunities the unification of parts with a car VAZ-2131. The type of transmission of car, 4x4, with a constant differential drive on all wheels, and the front and rear suspension on the basis of the car VAZ-2131, optimized for elastic characteristics and angular stiffness due to application of new springs and shock absorbers. A five-speed трехвальная gearbox with synchronizers on all gears (except rear) via a short intermediate shaft with the hinge of equal angular velocity transfers torque to the transfer box. Two stage transfer box is equipped with a centre differential with forced disconnection. From the transfer box via PTO drive shaft torque is constantly transferred to the front and rear driving axles. The front split. Carter main gear is rigidly " tied" to the engine block. With front wheel drive home the pair is connected swaying half-axes with the joints of equal angular velocity. Rear axle неразрезной with a rigid beam. Used "нивовский" the bridge, but the beam is strengthened. Front suspension independent with a cross swaying levers, coil springs and hydraulic shock absorbers. There is a stabilizer of transverse stability. For the front suspension of almost everything - "нивовское", only spring original, with increased stiffness, and changed the characteristics of the shock absorbers. The associate of the rear axle (which is also almost repeats the "Niva"), the changes more - except for the springs and shock absorbers changed brackets of the latter and the tie bar. Produced two modifications: with карбюраторным engine working volume 1,8л (VAZ-2130) with a capacity of 80 and with the engine with distributed injection of fuel of capacity of 1,7л (VAZ-21214) and 84 HP. In the future it was planned to install on a minivan new two-liter engine.
