The author of the next all-terrain vehicle has quite a lot of experience in assembling machines of various designs. Therefore, in fact, this all-terrain vehicle was built professionally as a means of delivery for winter fishing. This property consists in the fact that you need to come, drill, go fishing and get home. It goes without saying that this scheme excludes breakdowns, since fixing any malfunctions in the winter on ice is not the best solution, which is why the author, during construction, primarily adhered to the reliability of the structures. The place for fishing is not so far away, maximum 40 km, so even in the event of a malfunction, the all-terrain vehicle will be able to get to the garage.
At the very beginning of construction, the all-terrain vehicle was conceived as a light pneumatic with an ant engine, but changes were made during construction.
What mechanisms were involved in the construction of the all-terrain vehicle:
1) The frame was assembled independently from a profiled square tube.
2) Internal combustion engine from IZH, which was then changed to Jupiter 5.
3) Disks removed from previously made all-terrain vehicles
4) An electric fan for cooling from an unknown model of a Japanese small car.
5) rear differential with axle shafts from Toyota Lit-ice,
6) front differential with axle shafts and hubs from Subaru Sambar,
7) The steering wheel and steering rack from the same Subaru.
8) door glazing borrowed from Honda Street.
9) The electric fan was removed from the Daihatsu Charade.
What are the disadvantages of the design of this all-terrain vehicle:
1. there is no possibility of reversing.;
2. The engine is located inside the cab, hence the constant noise.
3. small load capacity;
4. There is simply no rear suspension.
Pros:
1) The design is very light
2) Soft and smooth wheels do not dig a hole in the ice, which makes it easy to overcome such obstacles, and allows
ride in any weather.
3) Swims slowly, easily enters sandy (rocky)
shore, but most likely will not leave the ice itself.
As for cross-country ability, it rides in powder until it hits the snow with its muzzle, then it starts to slip, but it doesn’t sit on its belly, you can roll back,
or trample ahead (very difficult). Also, very good handling is noted, the turning radius is smaller than that of the Niva, directional stability for such a short base is also not bad. The maximum speed of the all-terrain vehicle on a relatively acceptable road is under 60 km / h.
The essence of the work of the all-terrain vehicle is quite simple: the chain from the engine goes to the intermediate shaft, and from it to the rear and front differentials. The design feature is such that the front axle has the ability to turn off.
Let's move on to the phased construction of the all-terrain vehicle.
To begin with, the frame of the all-terrain vehicle was assembled, it was built from square pipes, and then the main elements were already inserted into it. Therefore, the dimensions were taken upon the fact of action without drawings and diagrams. Then the all-terrain vehicle suspension and steering were assembled.
When installing the rear of the all-terrain vehicle, there was an idea to make depreciation, however, for the sake of the prostate, and hence the reliability of the structure, it was decided to abandon it. In addition, the all-terrain vehicle turned out to be much easier.
And here is the front view of the hub:
This is what the back mount looks like:
The next step was the installation of an internal combustion engine, and the steering wheel was adjusted to the convenience of the author. It is interesting that the steering shaft had to be made of a composite structure on cardans. Well, then the author began to weld a common frame for the cab and body. Moreover, the wheel disks were taken from early designs, and they are slightly different in size.
The cameras are taken in size 1200/500 508.
In the images below, the main work on installing the frame is just being done.
The design of the model is quite good. Another important detail, the author specifically decided to limit the carrying capacity of this all-terrain vehicle. Again, this was done in order to enhance the reliability of the all-terrain vehicle, so as not to overload the structure with excess cargo.
After trial runs, it was decided to change the intermediate shaft star from Izh to a larger star.
But by the way, photos of the area in which the all-terrain vehicle will be operated.
It hasn't snowed that much yet:
In autumn it looks like this:
As it was originally intended, the technique turned out to be quite easy, one person is enough to be able to lift the front and back in turn, and at the same time rearrange it from the track to the side.
This was achieved thanks to the unrealistically low weight of the structure of 300 kg.
But unfortunately there were also disadvantages, for example, in deep snow, the engine was weak, so it was still decided to sacrifice weight in favor of a more powerful engine from Jupiter 5.
The wheel assembly was weighed:
Scale disk:
The rims on the front wheels are different in diameter, external and internal, experimented during construction. The rear wheels are the same. There is no big difference.
For cooling, an electric fan was added from the radiator of a small Japanese car.
And the warm air from the engine was directed to the heating of the windows. Independent brakes were also installed on the left and right front wheels, this was necessary to overcome the diagonal hanging.
After such upgrades, the front of the car became noticeably heavier, but the dynamics and speed gave the necessary qualities, thanks to the new engine.
Since the wheels were taken from previous models of all-terrain vehicles, it was decided to slightly modernize the wheels:
Chain tensioners were also installed on long levers connected
springs:
Once the increased mass had an effect, when the karakat rolled over on its back, it was no longer possible to lift it alone, but together they easily managed.
Mini snowmobiles will be useful to every fan of winter fishing. Such equipment is very easy to operate, no special training is needed. Many fishermen are attracted by the affordable price and functionality of mini snowmobiles.
After all, with their help, you can overcome long distances much faster, and the process of moving even in deep snow is much easier.
They are usually very easy to disassemble and assemble, so they can be transported in the trunk of a car. This type of transport is very profitable, because some models do not require registration.
The main characteristics of mini snowmobiles
Such units are being improved every year, more and more new models appear, more comfortable and simplified control conditions.
Weight and dimensions
Almost every model has a small weight and dimensions. This is very convenient, because a small structure can be easily pulled out of a hole, which can be difficult to notice under a layer of snow. Also, the fisherman will be able to independently load into the car and pull it out of the trunk.
Design
Such a snowmobile consists of several modules that can be easily disassembled. And the fisherman himself will be able to load the transport into the trunk of his car.
Also, the design feature allows you to significantly save on repairs and maintenance, because it will not break so often. To store a mini snowmobile, you do not need to rent a room. Some models have a cam-lock system with springs, which allows you to assemble the structure in just a few minutes.
Speed
They can easily move at a speed of 30-35 km per hour. This is quite enough to safely drive a long distance on snow or ice.
Other benefits
- Under the seat there is a comfortable and wide place where the fisherman can put all the gear necessary for fishing.
- The mini snowmobile is equipped with a centrifugal clutch with a drive, which greatly simplifies control.
- This technique is equipped with special skis made of durable metal. They are very reliable and stable, and in case of breakage they are easy to change.
How to catch more fish?
For 13 years of active fishing, I have found many ways to improve the bite. And here are the most effective ones: - Cool activator. Attracts fish in cold and warm water with the help of pheromones included in the composition and stimulates their appetite. It's a pity that Rosprirodnadzor wants to ban its sale.
- More sensitive gear. Read the relevant manuals for the particular type of tackle on the pages of my website.
- Lures based pheromones.
Advantages and disadvantages of mini snowmobiles
The main advantages of small-sized models include:
- The light weight and size of the equipment makes it easy to transport disassembled or assembled even by one person.
- The ability to disassemble it, which greatly simplifies storage, because you do not need to look for a large area of \u200b\u200bthe garage, they can easily be stored even in the house.
- It takes only a few minutes to assemble the structure.
- On mini snowmobiles, you can move together at a speed of 20 km per hour.
- Under the wide seat you can put all the gear. There are many additional pockets that will conveniently accommodate all the necessary little things for fishing.
- Some models have additional features, such as a heated steering wheel, or even a 12V power supply.
Mini snowmobiles also have some disadvantages that you should remember so that unforeseen unpleasant situations do not arise:
- The fuel tank is small, so in order not to get stuck halfway, it is better to stock up on additional canisters of gasoline.
- Despite the fact that such a technique can withstand two people, but comfortable movement will not work. However, if you do not go far, then you can endure a little, because walking on foot is much worse, especially on slippery ice or deep snow.
- The legs are not protected during movement, so you should move carefully so as not to hurt the limbs.
Collapsible snowmobiles
Many fishermen prefer to use collapsible ones, they believe that they are much more convenient and practical. But in fact, such models have only a few rather minor features in the design.
For example:
- The weight and size of the vehicle is much larger. Which sometimes becomes a problem, because all the parts may not fit in the trunk of ordinary cars.
- The speed of movement is much higher, thanks to the increased engine, you can drive 70 km per hour.
- The assembly of the structure takes much more time, because it is an order of magnitude more complicated.
- Large size allows you to comfortably accommodate several fishermen.
- Its carrying capacity is much higher than that of mini snowmobiles.
Polar models and brands
You can find many such models that have gained immense popularity not only in Russia, but also in many European countries. Among the popular mini snowmobiles, there are both foreign and domestic manufacturers.
The best are:
- "Burlak"
- "Snowstorm"
- "Tourist"
- "Snow Fly"
- "Zander"
Domestic brands are very popular in our country "Walk around" And "Burlak". They are lightweight and take up little space when disassembled. In addition, they can reach a decent speed, about 20 km per hour, despite the large load and two passengers. You can collect them very quickly.
snowmobile "Snowstorm" has all the necessary parameters. They are easy enough to operate even for a beginner. There are no problems with driving on a very snowy road. This model is equipped with comfortable and powerful skis that allow you to ride even off-road.
Model "Husky" has very small dimensions, so it is convenient to keep it even in a small house, for example, on a balcony. Assembly takes only 2-3 minutes.
"Tourist" has a very simple control system, so even a beginner or teenager can cope with it. Lightweight design and compactness make it simply indispensable. It is economical in terms of fuel. And you can start it even at very low temperatures.
When choosing a particular model, you should pay attention to their reliability, safety and quality. It is better to take snowmobiles of famous brands, because they have already proven themselves to be the best and have all the necessary characteristics.
Also, it is important to take a snowmobile that consumes as little fuel as possible, this will save a lot, and not get into an unpleasant situation.
Where to buy and at what price?
You can buy them in a specialized hardware store. You can also find them in large stores that sell everything for fishing. The easiest way is to order online. There is always a large selection, and you can find exactly the model that will satisfy in terms of its characteristics and price. But it is worth buying only on official sites, so as not to purchase a fake.
The price of a mini snowmobile depends on its model, characteristics, quality and manufacturer. The cost of such equipment varies from 60-150 thousand rubles.
Reviews
Fishermen often use mini snowmobiles for winter fishing, because without them it is very difficult to bring all the necessary gear and things to the place of fishing, especially on slippery roads.
A user under the nickname "Rybak2000" writes that he has been using the Dingo mini snowmobile for several years. At first I thought for a long time which model to take and at first I did not want to take this one. But friends persuaded. I am very pleased with the purchase, in all respects the snowmobile is just fine. Rides on any road, very comfortable, you can load all things. Never regretted my choice yet.
