Materials and aggregates involved for the construction of this model of the all-terrain vehicle:
1) Engine internal combustion Lifan with a capacity of 15 hp
2) four-speed gearbox from classic vase
3) dispensing box from the car Niva
4) Swivel fist from UAZ
5) T-150 wheels encouraged

Consider in more detail the main nodes of the design of this all-terrain vehicle.

The fracture assembly was created from the swivel fist according to the UVAT scheme.

There are two profile belts in, as well as a small pulley on 100 and a large pulley for 300:

Wheel discs were created from T-150 disks, which were wrapped in iron 2 mm thick, as well as taken welding around the perimeter. The fastening of the tire to the disk is done with the help of shut-off wheels, and the inner side is welded with a tire, which hold the tire. The tire itself dresses on a disc with a tension, which gives even more fastening strength, plus the author used the sealant. Is there enough such attachment to show tests.

A frame from the profile pipe was made by welding, and bridges from VAZ 2105 are installed on the frame, the gear ratio is 4.1:

Initially, the author wanted to make landing on the hub independently, but it turned out quite difficult and unreliable, so I had to invest more funds in the all-terrain vehicle.

The weight of the most expensive thing in the assembled state is equal to 550 kilograms. Also, the author began to prepare all-pass for swimming.
Fasteners were painted to semi-axes to immediately notice cracks if they could not stand the tests. Although the design should not be touched, as the washers are fed on both sides and this is quite enough according to the calculations.

Was found steering. Rake steering wheel was taken from VAZ 2110, but its move is too small and this is not enough for convenient control of the all-terrain vehicle. Therefore, in the future, the author plans to either replace it, or establish an additional lever to correct the direction of movement, as well as increase the traction.

Then it was made fastening the swivel fist and the rear semi-frame in this way:

To create a rotation assembly, a fist from the UAZ was used.

Further, the author considered two ways to create a transmission of the all-terrain vehicle.
First, you can remove disposal box and install the chain reducer, then the speed will decrease, but the chains become an additional vulnerable place Wheaves, over which will need to work.

we will have to shorten the frame, and make a more balanced routing of the front of the frame.
Secondly, if you leave a dispensing box, you can simply replace gearboxes on a penny with a gear ratio of 4.3. In this case, we also get a decrease in speed, but not so much as much as I would like.

Regarding the ravings, there is the possibility of the front axle to cut off and rebuild the shank above, so that it is almost close to shift the design to the transfer box, it is not entirely clear about the oil level in the gearbox and how it will affect the operation of the system. It is also possible to disassemble the distribution box itself in order to reduce the number of reduced transmission, but this requires a serious approach to the study of technical documentation.

Also, to strengthen the rotation node, it is planned to install a couple of shock absorbers from Zila:

The all-terrain vessel was left to the sun out of the garage, the sun heated the tires of the machine and it was spontaneously unfolded, which is quite unpleasant and indicates the insufficient reliability of tire fastening.

Urgent measures to strengthen fastening were taken:

Was inverted steering Reika, as well as the knot destroyable during loads, after these actions, the steering has become much more convenient.

Yes, the design is rather weak and not reliable, but for some time it will be suitable and it will be possible to test the car.
The role of clutch at the all-terrain vehicle is performed by two belts. During the trip, one of them flew away for an unknown reason, the author decided not to put it back in the field, but simply remove and get to the garage on one belt. It was noted that the all-terrain vehicle with one belt feels much better, the smoothness of the stroke appeared, and the main thing is rushed from the place without jerks.

Regarding the destroyable element of the structure, it was made in this way: one bolt was removed, and the edge twisted on the aluminum wire, so that during loads it would simply be flexing traction relative to each other. It is also quite convenient to adjust the power of the load by a simple increase or decrease in the number of turns of the wire.

During tests, broke tie Rod, so this element also needs to be improved.
For example, installing the pump from the steering NMZ 236,238, as it is immediately made under profile A, instead of NSh-10.
Silent means consent! I am really sure that the installation of data (similar) units will greatly simplify your life. Indicate the NSH-10 easier to use the pump from the steering NMZ 236,238, it is immediately made under the belt profile A (if not mistaken)

Steering system weighing 4 kilograms:

Hydraulic cylinder weighing 5-7 kilograms:

It is also planned to install bridges on the springs to reduce shock loads on the construct of the transmission itself, which will increase the speed and smoothness of the trip. It is possible to modify the hinge by replacing the swivel fist into three supports and the strut, although the sickening node of the frames completely withstands the load and justifies itself.

But with wheels there are really difficulties.

The wheels turned out very heavy, with a disc weigh about 85 kilograms. In addition, there is no central track, the all-terrain route shakes. So in the future the author plans to replace their other lighter.

Also, the author wants to remove the dispensing box from the Niva and install the chain gearbox. There is another reason for which the author wishes to get rid of the transfer box, this is the speed of all-terrain vehicles. On the first reduced gear, the all-terrain vehicle moves at a speed of about 5 kilometers per hour, and this is on idling Engine. It is certainly tolerant, but still for minimal speed too much, too much load will go on bridges and the engine itself when overcoming complex obstacles.

Review of the designs of "broken" frames.

In an ordinary person, the phrase "breaking frame" is associated with a severe breakdown of a truck or an SUV.

However, there is engineering solutionswhich are specifically designed for such an opportunity to "peer" frame without consequences :).
This is done to increase the passability and maneuverability of the car.

Back in 1919 Italian Pavesi Engineer designed car tractor high passability Fiat-Pavesi P4 with very large wheels. For the rotation of the car, the principle of "breaking" frame was implemented. (Source - Patriot4x4.ru)

In our country, in 1961, on the instructions of the government was developed Tractor K-700 with a broken frame. The purpose of the project was to create the first domestic wheel tractor, fifth traction class. In the photo Tractor K-701

The half-frame of the tractor K-700 has an impressive dimension

And who does not remember the urban articulated bus Ikarus-280?

The unique properties of cars with a broken frame combined many designers to implement such a solution in various types of all-terrain vehicles. Moreover, both single-skinny and industrial scale.
Here, at least remember the Swedish caterpillar swamps, which has many imitators.
But in the ranks of the wheel equipment there are something to see:

Connectants

Connectants that produced the Severodvinsk firm Difthong, have two sections of the swivel-coupling device, which allows the links to develop each other in the horizontal plane.
Snow-blurry are described in the journal Autored for 2006

Tractor "Sibiryak"

In the Siberian installed a hinged-articulated frame

The most interesting is the central hinge knot.
It consists of a power corps that is back front semiracy, hinge equal corner speeds (Sls), transmitting a torque to the rear bridge, and a ball housing, hinged and filament.
The shank of the ball is inserted into the special housing of the rear half-weather and has the ability to rotate in it when the interconnect is changed. A special housing is associated with the rear semi-frame with two 20 mm plates.

The power body welded from 20 mm thick sheets. Perceives the loads acting on the machine in the vertical plane, and the ball support, fixed in the conical housing bearings, serves to turn the seats relative to each other in the horizontal plane.
This movement is carried out by the watercill, installed between the front semi-frame and the ball support bracket.

The basis for the central node was the details from the swivel fist front wheel Car ZIL-131 Identical car-66 car design, but different sizes.
The shank of the ball housing and the shanks of the semi-axes of the leading and slave shafts of the Sls have been refined.
Bearings in the axial joint are bronze bushings, and traction (longitudinal) efforts are perceived by a stubborn ball bearing. The hinges cavity are sealed with grease and appreciated by consistency lubrication.

Central hinged knot:
1 - Bearing 60212; 2-pin M10 (6 pcs.): 3, 10 - stubborn rings (steel 45, S2). 4 - kkvorn; 5 - cuff (from the standard node); 6 - Spring Ring; 7 - cuff (1-115x145); 8 - liners (bronze): 9 - spacer; 11 - Nut stubborn; 12 - Bearing 8212; 13 - nutty nut; 14 - Special Corps; 15 - Case Central Sharply Hinged Knot; 16 - Ring; 17 - shaft slave; 18 - ball housing; 19 - shaft presenter; 20, 26 - Bearing hulls (steel 45). 21 - flange (CRAM. 45) 22 - nut M32; 23 - hairpin M5 (6 pcs.); 24 Bearing conical (regular); 25 - Bearing Cover: 27 - Sealing Ring (Rubber); 28 - cuff (1-85x110); 29 - steering hydraulic cylinder.

Often, the rotary assembly for all-terrain vehicles are made of a swivel fist of the front wheel all-wheel drive car, for example, from a swivel fist UAZ

UAZ-Keper with a twisted frame

Using technology that has been worked out on "Caprals", a UAZ with a twisting frame was made. This is a camper based on Krasnodar autoclub "Kuban" and a truck based on UAZ-39095

FIG. 1 shows the type of vehicle in the plan; FIG. 2 The same, side view; FIG. 3 Bearing Unloading Scheme.
The articulated vehicle 1 with a drive for all wheels contains two independent semirases A and B, interconnected with the possibility of relative movement. Between the semirases, the main hinge 2 is installed, having an inner diameter 3, sufficient for the free pass through it of the cardan shaft 4.
On the half-frame b coaxially with the bearing 2 on the brackets 5 there is a movable element 6 (as an element 6, for example, a shaft installed in the bearings, or a ball support, or a ball connector), rotating around the axis 7, can be used to the element 6 are all connected. Brux 8 and 9. The second ends 10 bars are detachable on the connecting elements 11 of the half-frames A. Ends 10 bars are separated from the longitudinal axis of the car 7.

Vehicle Works as follows.
When moving on the off-road half-frame A and B can move around the horizontal longitudinal axis one relative to the other at an angle to 23o. The possibility of mutual displacement provides a hinge 2 connecting the half-frames A, thrust 8 and 9, rotating on the element 6 and tracking the movement of one half-frame relative to the other, unload the hinge 2 and increase the zone of its performance (see FIG. 3). The emerging longitudinal power loads between the semiradias A and B are perceived primarily by connectors 8 and 9, as they are connected rigidly (without backlash), partially extinguishable due to their own elasticity, and then transmitted to the hinge 2.

When moving along the roads of general use, the power frame works in the same way as when driving down off-road, perceiving the maximum loads and unloading hinge 2.

The hinge in a non-working position is fixed with pins on both sides, which allows the car comfortably move along the roads of general use. (in the photo of the pins are removed)

This design was originally tested on cargo-passenger car UAZ-VD "Varan"

It was built for fishing trips, berries and mushrooms. The author tried to use the most accessible details to save money so that the all-terrain vehicle was budget. The all-terrain vehicle was built by the author together with the Father, who was engaged in all welders.

Materials and aggregates used to build this all-wheel drive:
1) Bridges from the car Moskvich 412
2) SCD engine with forced air cooling
3) swivel fist from UAZ
4) Reverse Reducer from Szd
5) Additional chain reducer
6) Steering from M-41
7) Wheels W-3 Lightweight
8) Profile Pipe
9) hub from VAZ 2108

Let us consider in more detail the stages of construction and the main nodes of the all-terrain vehicle.

To begin with, two semiraplas with a size of 1600 per 700 of the profile pipe were welded. The bridges of the all-terrain vehicles were installed in the middle. As well as a node was made of a fracture frame of the swivel fist UAZ according to the UVAT scheme.

After that, work began on the creation of disks for the all-terrain vehicle. The design of the disks was made as simple as possible and reliable. The diameter of the shut-off rings is 510, although it was originally planned 530. The truth is not a strong role played.

Then the author began working at the rear of the semiracy.

Then the markup of the main elements and their layouts in the all-terrain vehicle began. In particular, the author decided to see much better establish the subframe of the engine.

At the same time, work continued on the separate designs of the all-terrain vehicle. A cardan shaft was made, which transmits rotation from the gearbox to the VAZ 2108 hub, and then through an asterisk to the cardan shaft of the Muscovite bridge.

Basic lathes were commissioned by the specialist of this case.

It can be seen below how the hub with a Muscovite shank is connected.

Then the steering rack was installed from M-41. The rail was installed according to the UVAT scheme:

It was shown how the steering traction from the UAZ and M-41 was shredded:

Welding work on the front semiracy of the all-pass:

The gearbox in the Moskvich bridges were inverted, as well as a gearbox from Szd.

After the gearbox was disassembled, the author brewed in it differential and began assembling with a subsequent installation in his place in the construction of the all-terrain vehicle.

After the two front wheels of the all-pass wheel were completed, the author decided to install the roof:

In the rear parts, a profile of 40 per 25 thickness of 2 mm was used. Moreover, on the last upper profile it was made cut, in order to be able to wear a ring. On the front two wheels of the lower profile of the same size 40 to 25 and a thickness of 2 mm, and the upper 30 is 30 mm. The creation of the front passed much easier and the wheel was easy to easily, unlike the design of the rear wheels.

After the completion of the main work on the transmissions of the all-terrain pass, the author began the field testing of the machine. After the first tests, some flaws of the construction of the all-terrain vehicle were revealed. In particular, they were in incorrect work of the clutch of all-pass, as well as shifting gear. Therefore, the author engaged in finalizing the transmission from the engine to the gearbox and clutch box. For this, the native motorcycle clutch cable was replaced, as it squeezed too hard, which did not give the smooth gear. Also on the all-terrain vehicle was installed exhaust pipeIn order to reduce the noise of the car.
