“JEEP” – SIMPLY AND RELIABLY

Residents of the Armenian capital like cars and know a lot about them. This convinced us to visit Yerevan streets with design engineer ERISA by Stanislav Hopenosis on his makeshift Rover. Wherever we stayed, immediately gathered around the curious passers-by. Followed inevitable in such cases, the questions: what? how? from what? Stanislav patiently answered. For three years from the date of first departure on the new machine, he was used to these “press conferences”.

Especially often had to talk to the fans in 1983, during the traditional run of homemade cars. Rover, who had finally received the first prize, invariably the centre of attention at stops throughout the run.

 

Cosmonaut Vladimir Dzhanibekov, who rode with the convoy most of the way and sat behind the wheel almost all the diys said about it: “Comfort, breadth of the review, beauty!”

 

But even more popular C. Chopanova brought the TV show “are you the motet” dedicated to improvised transport. At the request of the viewers and readers of the journal “modelist-Konstruktor”, we introduce the design of his vehicle.

Conceiving the car, Stanislav decided to lay in his constructive simplicity, reliability, ruggedness and availability of service. When you select a layout stayed the scheme “jeep”, but his version of the classic was different in that it only has one drive axle – rear, for ease.

 

Externally, the jeep looks smaller than, say, LUAZ, although the size of the cabin and trunk is not inferior to him. This is achieved, firstly, dense “packing” of the engine compartment and, second, the external location of the Luggage (roof), spare wheel (left side) and canister (in the rear). Total weight – 900 kgs.

1 – front beams (50X25 mm), 2 – the components of the front wall of the engine compartment (50X25 mm), 3 – cradle engine mounts, 4 – bracket of the shock absorber, 5 – front spar (50×50 mm), 6 – beam hood (40X40 mm), 7 – the elements of the rear wall of the engine compartment (50X25 mm), 8 – threshold (50 X X25 mm), 9 – rear spar (40X40 mm), 10 – Board (25 X 20 mm), 11 – rear cross bar (40X40 mm) 12 – drip rail (25X20 mm), 13 – tow bracket, 14 – earring of a rear spring, 15 – arch rear wheels (25X25 mm area), 16 is an intermediate cross bar (40X40 mm) with the fingers of the shock absorber-to-body, 17 – bracket rear; springs, 18, 21 and door rack (40X40 mm), 19 – front cross bar (40X40 mm) 20 – the struts (50X25 mm) ( 22 – earring of a front spring, 23 – bracket front spring.

 

Simplification, however, did not affect the seaworthiness of the machine. Built in 1981, it was about 150,000 km Every year on her trips from Yerevan to Moscow and back. Last time with a homemade trailer giving a weight of 500 kgs. Participation in the rally is much lengthened this journey. However, the design withstood the test of roads of Karelia and the Kola Peninsula. “Jeep” was confident and on the highway (at speeds up to 120 km/h), and on the bumpy track.

Used S. Hopenow was helping a stranded fellow motorists pushing their cars front bumper of his Rover.

 

In his native Armenia, he raised it to a height of 3000 m above sea level, overcoming the lack of roads, scree, slopes up to 30°.

 

The hardships of the way are easily transferred in a comfortable and cozy salon of the car. In hot weather, you can move any of the four side Windows for fresh air. Or, if that’s not enough to open the sunroof.

 

A lot in the car and other simple and original design solutions. For example, how to construct the body. It consists of a space frame and cladding. Frame, designed for heavy torque and bending loads, welded steel pipes square and rectangular cross section. Less loaded bonnet, doors and rear window are made of channels, t-angles connected with rivets.

1 – lower support Cup, the spring is removed. Instead, it is welded spring cushion, 2 – mounting bracket upper torque rod (deleted), 3 – left spring cushion (welded).

 

 

Fig. 4. Adapter

 

The floor in the cabin and the hood lining is made of corrugated duralumin sheets 2 mm thick. the Sheathing body is of the smooth sheets with a thickness of 1.5 mm. they are attached To the frame with M5 bolts with countersunk heads. The hidden joints of sheets of rubber and metal plates.

 

The cabin inside is lined with a thin layer of foam and soft plastic. Laminated safety glazing, and doors the rubber seals of cars of the Volga car. The floor is covered with rubber and synthetic rugs. All this reduces the noise level in the cabin and prevents the penetration of dust.

 

Instrument panel and the glove box is homemade. Front seats flip forward backs – “Zhigulevskoe”. Passenger rear seat designed for three people, self-made and has a fixed backrest. Behind him, down – fuel tank capacity 45 l (“UAZ”) with the neck, taken out over the rear bumper. Above the tank there is an internal trunk. Access it through the back window.

 

The principle of “ease plus the reliability of the” spread of the powerplant: the engine and gearbox together with service their units of “Lada – VAZ-2101. Only paper oil filter replaced by cheaper to operate . the inertia from the ZAZ-968.

 

Rear axle, with the possibility of towing a trailer, taken from the VAZ-2102 and slightly modified: removed the lower bearing Cup suspension springs and mounting brackets upper torque arms. Instead of the beam axle welded two U-shaped patesserie pillows.

 

The springs used on the front suspension of the car UAZ-469. Each package consists of five sheets coated before Assembly with graphite grease. To the frame of the body they are suspended in the area of the rear spars.

 

In addition to springs, there are telescopic shock absorbers. Rubber mount tanks they are, as in “Zhiguli”, are attached to the rear axle brackets and hinges or casing to the fingers on the intermediate cross member of the frame.

 

Torque from the engine and the rear axle is transmitted to the propeller shaft from “Volga” GAZ-21. The choice of this type due to the fact that it is more simple and reliable and requires no special care. However, bore holes are not the same, so for attaching the shaft to the flanges of gearbox and axle machined adapter.

 

They are steel washers Ø 100 and a thickness of 33 mm, which drilled eight holes. In the four corresponding holes in the flanges, tapped M8 and the other M10.

Driveshaft shortened – after measuring the distance between the adapters installed in the lathe centers and clipped: in place of the existing pipe joints with the rear fork and at the place of the future connection. Excess removed, and the parts tack-welded by welding at four points, and after checking shaft runout welded completely.

 

As for the front axle, it is completely improvised. When designing it, Hopenow was guided by his favourite principle of “simplicity plus dependability.” The reasoning was something like this: the front axle is a very important unit. It provides control of the movement, from its “well-being” depends on the “health” of the entire car. Therefore, the less it will be parts and movable joints, the better.

 

Three years of operation showed that the decision was correct. What are the only stones and potholes go iodine front wheels – all uneasy. Here is how to construct the bridge.

 

The main element is a thick-walled seamless steel pipe Ø 60 and a length of 1100 mm. welded patesserie To her pillow, the fingers of the shock mount and the support pad ball bearings front suspension.

1 – knuckles, 2 – upper support platform, 3 – bolt upper ball bearing, 4 – panel, 6 – tube 60 X 25 mm, 6 – the main tube, 7 – adresserna Playground, 8 – bracket axle shock absorber, 9 – bolt and the lower ball bearing 10 – lower support platform, 11 – axle shock-absorber.

 

 

 

 

Fig. 7. Steering:

 

1 – steering shaft 2 – universal joints, 3 – intermediate shaft 4 – steering gear 5 – unregulated pull, 6 – pull adjustable, 7 – twin lever right wheel, 8 – knuckles, 9 – single lever left wheel.

 

 

When assembling the front axle you need to consider the camber, so a reference platform joined to the pipe in a certain order. First welded bottom and screwed to them (also lower) ball bearings swivel axles “Zhiguli” of the wheels. The upper area is first attached to the appropriate ball bearing swivel trunnion, and then welded to the pipe. Moreover, the angle made 0°20′ – 0°30′, which corresponds to 2-3 mm difference between the dimensions taken from the edges of the rims of the wheels to vertical (pipe horizontal), was established with the help of a plumb.

 

To the frame body front axle is connected in the same way as the rear – springs (four leaf in the pack) with bolts and clamps and telescopic shock absorbers, the rods which rest in special brackets on the front spars.

 

The convergence of wheels is regulated for steering rod (from the “Volga” GAZ’21).

 

The Rover is also very simple and reliable. Turning “wheel”, the driver using two shafts and two hinge (ZIL-130), located under the bonnet acts on the steering gear, mounted on the front beams before the grille. Further, the unregulated force of traction is transmitted double (welded from two) lever right swivel pin, and an adjustable rod to the left lever swivel pin.

 

Briefly about the rest of the equipment of the vehicle. Brake system, Parking heater, lights and wiring is borrowed from the “Zhiguli” VAZ-21011, taillights – trailer “SKIF”, and the wiper and control devices used by UAZ-469.
