 His emergence in the early 90's «Gazelle» not only hit, as they say, «gold», gave fresh strength to the dying plant, but also gave a sense of dignity former «Soviet», they say, and we are able to do something no worse « West ». And to this day «Gazelka» is one of my most favorite cars - nice mordashka, thoughtful proportions, hardworking, unpretentious and accessible, although not devoid of some nedostatkov.Prochno winning position in the intra-and intercity transportation, «Gazelle» trying to infiltrate and in the outback, where the roads are marked only on the map. In general, parquet truck tried to adapt to the roads, running a car by the formula 4 × 4 (ie, making Full power). And although it is quite another diocese type vehicles UAZ class, but the whole trouble is that apart from GAZ nobody could (or not tried?) To «the flow» of any decent low-lift truck, with good quality and affordable price. 

 Therefore, and are born into the world Full power GAZ-33027, 27057, 33029. To be fair, that «Gazelle» with all the wheels quite confidently moves on the bad roads and the «moderate» off. Car structurally quite simple, although it has some drawbacks (noise «razdatki», include shortness of reduced transmission and locking differential, the problem with the hydraulic booster is too soft and expensive «rubber», large overhangs, insufficient clearance, dvuskatnye tire rear axle and reducing cross - etc.). 
 However, it is possible another version of the modernization of some forgotten car drastically increases its cross - this conversion chassis with 4 x 4 in half-circuit when the rear wheels instead of caterpillar engine installed, and front-wheel drive - managed. 
 Compared with the high-wheeled vehicles cross semi-cars have a much larger engine of the clutch with the ground and smaller unit pressure on the road. Semi-adapted vehicles more than a tracked vehicle, to apply them as a fast transport vehicles and trucks as in lung and secondary roads, and for long-term movement of good roads. 
The management of vehicles on the semi-snow virgin soil, where the use of other types of road transport severely hampered or even impossible. 
Modernizing serial GAZ-3302 in semi-option (without the front-drive), can remain in cost and technology group GAZ-33027, significantly increase the cross-base model. 
Moreover, modernization would be available to any serious tuning company (not to mention the fact the plant). Semi «Gazelle» should not be regarded as another type of army ATVs. Still, this is a comfortable truck off-road to let the bad, but roads and is designed primarily for communication with the provincial hinterland regional centers in adverse weather conditions (rain, mud, snow, ice, sand, road potholes, etc. .). 

When upgrading «Gazelle» can be used by virtually all production units and units that will favorably affect its value and remontoprigodnosti.Modernizatsiya GAS - 3302 includes: 
1. Install the brackets on the frame modified the front springs (used in gas-33027), which would lift the car by 70 mm. 
2. Instead, radial tires 175R16S use the diagonal at 17-18 inches. 
3. The installation of improved power steering, or a change in gear ratio steering mechanism with 22.46 to 32-35 (which is in principle possible, given a sufficiently low relative velocity semi-car). 
4. The rear axle is fully used, removing it from the springs and tightly securing the bottom of the frame, after relegating the more the level of the intermediate support cardan. This is only the front segment cardan transmission. Perhaps incision rear axle in a vertical wall channel frame (after its pre-amplification), which will favorably influence the angle of installation cardan. 
5. Between PPC and rear axles to install cardan shaft with an intermediate torsion vibrations dampener. 
6. Instead, install the rear wheel drum star, who will transmit torque from the engine on track. Base diameter - 400 mm. Possible stars a size chosen depending on the type and condition of the roads (more speed or more «cross»). 
7. Support rollers (3 pcs. On each side) - rubberized, large-diameter (500 mm). Latest rink (sloth) serves to regulate the tension of caterpillars. Running resource rollers - virtually the entire life of the car. 
8. Suspension rinks - an independent, torsion bar. Dial-plate torsion in pipes attached to the bottom of the frame, thereby increasing its lateral stiffness in torsion and more evenly distribute the load. You can set the front wheels of bilateral absorbers. 
9. The crown of modernization - road wheels mounted on rubber steel tracks (200 mm - 300 mm and symmetrical - asymmetrical, for heavy off-road and snow). Rubber track (like Gudrich) with a number of steel cables zavulkanizirovannym perceived traction is the best option for high-speed transport. It is cheap, has good reliability and durability. The biggest drawback (as compared to metal) - increased resistance to movement at temperatures below-20oS that principle to the areas north and not so - for the temperate latitudes of central Russia and Ukraine. 
10.Vybrannaya half-car circuit with controlled front bridge avoids easy road in the mechanism of differential rotation with special on-board friction or planetary mechanisms. However, the inherent lack of half-car povorachivaemost due to the fact that: a) when turning corners at large tracked vehicle must make a significant movement of soil or snow, otgrebaya him throughout the length of a reference track, and b) the load on the tire steering angle is not sufficient to ensure small turning radius and leads to a braking system on the car razdelnoy.Dlya total braking the car would be a central braking system is driven by foot pedals. And podtormazhivaniya a track (to reduce the turning radius and to eliminate probuksovyvaniya - a differential lock) - distributed lock braking system (a prototype on-board friction clutch) with a manual system or a pair of pedals. 
11. A flat increase in gas-tank (120 l) mounted inside the frame of the torsion bar. 
12. Final system it is desirable to withdraw up (to reduce fire hazards Field), and air filter to provide a cyclone pre-air cleaning from dust. 

Additional options: 
1. Front «kenguryatnik». 
2. The electric winch with a block. 
3. Fog lamps. 
4. The metal front bumper instead of plastic. 
5. Independent front podveska.6. Transmission brake. 
7. Inserted at the passenger loading platform module. Attachment module - snaps of the sides of the eye (which is tentatively before the shot). Fastening seat to the floor (longitudinal bar) - bolts. 
8. Developed traction-coupling. 
9. Trailer weight of up to 1 ton (4-wheel, with a torsion or rubber-zhgutovoy suspension, with an opportunity to put caterpillars). 
10.Vynesenny to «kenguryatniku» masloradiator increase. 
11.Zaschitnye exterior plastic lining on the entire bottom of the cab. 
12.Omyvatel headlights + headlight-seeker. 
13.Komplekt special. equipment (dump truck, drum, tower, crane, compressor, diesel generator, ladder, fire tank with the pump). 
14.Usilennaya protection of the engine crankcase. 
15.Dopolnitelnaya noise insulation and the bonnet, cabin. 
16.Komplekt front skis. 
17.Sistema prior elektrorazogreva (220 V, 500-2.000 W) with pumping of oil and antifreeze, running up the air in the cabin during the cold season. 
18.UKV (FM) radio (up to 10-12 km). 
19.Protivotumannaya siren. 
20.Opornye rollers instead of the front wheels to be used instead of full wheels in motion on the road at low speed. 
21.Polnaya preliminary bench running the engine and transmission under optimal conditions. 
22.Tekuschy full remkomplekt (gaskets, seals, belts, сайлент-blocks, oil filters, etc.) from the plant supplier. 
23.Podrobneyshaya instruction (in several volumes) for the repair and maintenance of the car. 
The set of puller, developments, devices, measuring instruments, etc. to carry out repairs in a Antarktidy.Vot, perhaps, and all that is needed and wanted to be deep and full modernization «Gazelle» in car-road (without ekstramer type of diesel engine and front-wheel drive). Of course, there are many skeptics who will ask a fundamental question: «Why? ..» And cause a lot of their arguments. 
And to put all points on the «i», I recall that the theory of semi «Gazelle» solidly stands on its «three pillars»: 
1. Basic model «Gazelle» long and serially produced in sufficient quantities, it is well developed as the manufacturer, as well as by consumers. The creation of semi-version based on the base - and the simplest way to get enough naieffektivneyshy interesting and practical version. 
2. Semi «Gazelle» according to the degree of complexity is not very different from the basic model. Indeed, perhaps even a more simple and cheap 4-speed CAT! Semi «Gazelle» constructively somewhat easier wheel «gazelles» (which is only a lack of box and front axle, 2 extra kardanov with the intermediate backbone, the rear springs!), So the price group, it should not go beyond GAS - 3302. 
3. At half-cross «Gazelle» will be competitive with the base models and UAZ «Nivoy», a snow virgin soil to completely overtake ih.Sozdavaya semi-version of «Gazelle», I operated the principle of «near podskoka». 
In other words, this is a comfortable and passable car - not for everyday work in heavy traffic conditions (there is a tractor with trailers), and to ensure movement in the village (town) - a city with a small shoulder of delivery of cargo (passengers) in the 20 -- 30 km. As ideal - the car the day off (but only in the traditions of the Russian hinterland, rather than Western European «weekend»), where the rural family (farmer) to market their exports of agricultural products, but instead of buying industry. goods, clothing, etc. 
In this case, the increased cost of fuel and rubber, together with the slow speed of movement (although it is bad roads, in any case not exceeding 40 km / h) more than offset by a comfortable cabin, spacious and hoisting platform and, most importantly - confidence in the movement in any circumstances.
