ATV “TRAMP-YUGRA” | MODEL CONSTRUCTION

The history of the vehicle is quite long. First began to be fit to travel on our road of “Niva-2121” – put her on the big wheel from the “Jeep”. Traveled on it with a neighbor (also, incidentally, an avid fisherman and hunter), but the cross for our seats acusados enough. Kupipi DPJ “Fields” copesa tires “Shine”. Clipped in the back of the arch, the post-Willie protruding wheel arches, so that the dirt is not cast on glass, and went back. In General, I liked it, only inside the little space and the water machine does not float. Wanted to do more. One friend hunter offered to change “Field” to the bus company “Trekol” bridges UAZ-31514 and a bunch of spare parts. We agreed, and then it all started: I decided to make a machine that could take you there, where no foot of man! Then began the search in the Internet and technical journals (including in the “Modeller-designer”) of various information on the construction of vehicles. Four months have all seen and read. Ripe and project the future of Rover.

Still 2-3 months collecting the parts. Bought a used UAZ-31514 10 thousand rubles, and VAZ-2109 8 thousand rubles as donors.

In may 2008 began construction, and in September of the same year, the Rover has already passed the first test, and as shown in the future – we coped with the task! In two years, hitting more than 7,000 km of major failure never had, always got back to the house on their own.

As is clear from what was said earlier, the engine capacity of 70 HP and a working volume of 1500 cm3 in unit with the clutch and five-speed gearbox was used on all-terrain vehicle purchased from VAZ-2109.

First of all, welded wheels (rims) chamber under a low pressure tire firm “Trekol” size 1300x600x533, designed for a working pressure of from 0.08 to 0.5 kgf/cm2. For them used the “vazovskie” wheels. Disks left intact, and the rims have usilili to 390 mm.

Like building a house start with the Foundation, and we all estimations started with suspension: assembled bridges from UAZ-31514 with homemade wheels and tires factory manufacturing “Trekol”. Bridges are placed apart at a distance equal to the future wheelbase (2970 mm – estimation, it was best for our vehicle) and began to try on the frame on the suspension of palwal-opticheskikh longitudinal leaf springs and hydraulic spring shock absorbers all from the same “UAZ”.

Frame welded, in the form of a simple, rectangular. It is based on two longitudinal bearing element of the spar, each consisting of a pair of steel tubes of rectangular cross-section 60×40 mm with a wall thickness of 3 mm. Pipe connected with each other through racks-reducers from the same pipe. In the end, every spar was the view of the farm. The side walls are connected to each other in the front and rear ends of traverses made of steel channel number 6,5, and in between-a few cross members from rolled different assortment. Front cross member is reinforced by a pair of struts for safety in a frontal collision. Moreover, attached to it front bumper mounted winch for samova-testimonia. Hanging on the racks of the Central crossmember transfer box is located, so it is also reinforced by struts, and this node is a extra subframe.

Then set on the frame and checked the position of the engine in unit with the clutch basket and gearbox. For their fixing to the frame at the spot welded suitable mounting brackets. To the side members and cross members in place welded the mounting brackets of springs and shock absorbers, components and control mechanisms, brakes, etc.

Upon completion of the arrangement and mounting of the units went to the manufacture of the body shell. It was cooked in place of steel tubes with cross-section 20×20 mm, with wall thickness of 1.5 mm. the body Frame sheathed 6 mm plywood. Plywood painted in four layers outside and one layer inside. In the ceiling of the body cut through the hatch and closed it leans back cover.

Diagram of the body frame

Outlay of the salon:

1 – handlebar and controls (UAZ-469); 2 – instrument panel (from the VAZ-2121 “Niva”); 3 – the driver’s seat (UAZ-469); 4 – seat co-driver (UAZ-469); 5 – the lever of a gear change; 6 – a lever to lock the center differential (from the VAZ-2121 “Niva”); 7 – the lever of inclusion of low transmission (from the VAZ-2121 “Niva”); 8 – passenger seat-lounger (2 PCs.); 9 – the sunroof (superimposed view); 10 – side door (2 PCs); 11 – a back door; 12 – the fuel tank (from the VAZ-2109, 2 PCs.)

Kinematic scheme of transmission:

Side doors in the back or two for the driver and front passenger-Navigator. In the original version of door used nivovskoe. But they are for our vehicle was too heavy, and subsequently, we replaced them with a homemade frame. For the rest of the passengers in the rear of the body is made of a hinged door.

On the front bumper (it’s from a UAZ-469) mounted winch for self-recovery in a hopeless situation, when the wheels spinning and the car is worth. But in one of the bogs when samovyrazheniya this winch was burned and we replaced it with a homemade – from starter VAZ-2109.

Brake system with vacuum booster – standard UAZ-469. From the same machine and steering with hydraulic booster integral type and all the pedals. The steering column is offset to the right a little bit, but you get used to that.

In front of the cabin is the stove from the VAZ-2108 – she blows on the windshield and warm the driver to the Navigator and under the front passenger seat, the second heater, from the car “the Gazelle” – the airflow from it directed at the feet of rear passengers. In the cabin warm even in 40-degree cold. Seat much and for group trips to fishing or hunting the rest mostly in our jeep – six people can be accommodated freely. That’s just the table yet. No glove boxes in the cabin – the small things placed in cardboard boxes behind the front seats.

“Tramp-Ugra”, in General, everyone likes the exterior design, and technical opportunities. But even more capacity.

There were some difficulties in obtaining documents on the car, i.e. that it “legalization”. But in the end these issues were resolved.

The vehicle has undergone a technical / / regional organization all-Russian society of motorists, and registered in the State inspection of technical supervision. Obtained the registration number of the vehicle.

However, the Rover continued to improve. In the summer of 2011, the year changed a makeshift wheels (rims) for commercial production and tyres – demon-chamber of the same company “Trekol” and with the same dimensions 1300x600x533 (the last dimension is the diameter) with a working pressure of from 0.08 to 0.7 kgf/cm2. Overhauled the engine. Went through the transfer case (it turns out, some time went without oil in it): changed all the seals, the housing attached to the frame on four pillows. Under the front panel did the so-called “glove boxes” – small stowage boxes. The casing body replaced with plywood on the metal of duralumin sheet thickness of 0.8 mm and further insulated cabin.

Redid the hood, now it opens forward to access engine was more convenient, redid the interior, replaced the rectangular block lights on a normal round. In General, the design lightened by about 300 lbs. then the permeability increased “significantly” (even the virgin snow half a meter deep Rover overcomes confident) and is not inferior to similar vehicles, whose price is far higher (about 1 million). For the construction of our Rover left 140 thousand rubles, not counting the cost of wheels. In principle, both are quite feasible budget option.

Well, what else to add to the characterization of the Rover? The longest journey over 300 km through the swamp, not counting the road on the highway. The most extreme trip – fishing in the cold under 40 degrees. The lack of one: and after the upgrade still a bit heavy – 1200 kg, but it is convenient to go with friends camping, a long trip (five people can sleep in full growth). In the future we plan to build a smaller all-terrain vehicle: at 2 – 3 people and weight up to 800 kg. In General, a real Rover to date, has already passed more than 10 000 km without serious damage, at least, always returned home on their own, and even sometimes had to take in tow the “distress” of fellow travelers.

As became clear from the description of the design, the vehicle created on the basis of domestic cars VAZ and UAZ, which facilitates and reduces the cost of its maintenance and operation.

Ending a story about Rover, I note that the original version of the body design, in my opinion, was better, but later we opted to maximize internal space and facilitate machine.
