Making pneumatic passages with your own hands on low pressure tires is quite possible. Such machines are popular due to their strength and versatility. A similar technique proved to be excellent in the summer heat and on snowy roads. As a basis for a home-made all-terrain vehicle, you can use a walk-behind tractor. The unit is a power unit with a rotating element designed for aggregation with various attachments. Such a device is able to transport cargo on a small trailer.
Engine
The power indicator on a home-made unit determines the performance of the selected walk-behind tractor. The higher this parameter, the more efficient the technique will function. On the other hand, high power leads to increased fuel consumption. If the owner lives in the outback, far from the gas station, this aspect will play a significant role.
Those users who plan to use the equipment only in the warm season are recommended to opt for a budget modification with a two-stroke engine. It is easier to set up and quick to start. For fishing and hunting in the winter, the four-stroke power unit will be the best option. Such variations warm up more slowly, providing a longer engine life.
Tools
To make pneumatic passages with your own hands, you will need a set of certain tools and devices. This list includes the following items:
- Welding machine.
- Hammer, a set of screwdrivers.
- Cutters for metal.
- Drill and grinder with nozzles for metal processing.
- Set of car keys.
From materials you need such things:
- Motor from a walk-behind tractor or identical agricultural equipment.
- Iron motorcycle or car rims on wheels to be treated with anti-corrosion coating.
- Cameras from aircraft or agricultural machinery.
- Pipe trimming.
- Steering column. It is advisable to purchase this part in a new form, since it will be responsible for the quality of control of the machine.
- Suspension elements (car hubs can be used).
- Metal corners and mounting hardware.
- Wire and fittings.
Pneumatic do-it-yourself motor-block: assembly
Before assembling the unit in question, make sure that all electrical connectors and contacts are suitable for each other. It is necessary to draw up a schematic plan or drawing of the proposed apparatus. It is also necessary to develop work stages and observe safety precautions.
The installation procedure is divided into the following stages:
- Preparation and cleaning of the workplace.
- Sizing the base frame and cutting pieces of pipes of the desired length with their subsequent connection by welding.
- Install prepared cameras on discs and check for leaks in the joints.
- Steering assembly. Particular attention should be paid to the quality of the column, the absence of damage to it and the correct fixation with a suitable galvanized steel bolt.
- Drive connection by mounting wheels and brake pads on a metal axle.
- Installation of electrical circuits.
After the implementation of these manipulations, you can proceed with the installation of the walk-behind tractor with your own hands on the airways. The base must be securely bolted. In order for the machine to gain an attractive appearance and get a longer service life, it is advisable to paint the case and open parts with protective materials.
Wheels
In the manufacture of the equipment in question, it is better to use parts from a truck or tractor with wide treads as wheels. Such modifications are distinguished by a deep pattern, which provides high traffic. Alternatively, tires can be lightened by eliminating excess rubber on the outside. Such "homemade" is called peeling.
A self-made pneumatic passage from a walk-behind tractor can be reinforced with low-pressure tires. They will provide traction on a surface covered with ice or snow. To do this, you need to adapt rings or chains made of metal, which will create additional rigidity during movement and improve the maneuverability of the equipment.
Features
Sometimes combined tires are used, aggregated with low pressure analogues. For wheels, galvanized metal alloy wheels are also suitable. Thanks to corrosion protection, they will last much longer than conventional metal options. Distribute and adjust the received load will allow the gearbox on four ranges from the car VAZ. It will also allow you to adjust the speed and optimize fuel consumption.
All-terrain vehicles based on the Ural
DIY do-it-yourself homemade pneumatic do-it-yourselfers from a Ural motorcycle. The main supporting part is the frame arc, consisting of pipe elements with a diameter of at least 4.2 mm. Structural rigidity is also ensured by pipes that form a reinforced triangle, and struts of the same material. Such a complicated configuration makes it possible to correctly distribute the mass of the all-terrain vehicle, taking into account the transportation of additional cargo or a passenger.
Do -it -yourself all-terrain vehicles on a motorcycle-type air suspension allow the use of standard seats. In this case, the mounting method remains the same. They are placed taking into account the complexion and growth of the average person in distance from each other. This provides the convenience of landing and travel. Factory-fitted seat handles change to rigid 24-centimeter crossbars.
This ensures the safety of the passenger, allowing him to hold securely while driving in difficult terrain. As an option, a drawer mount is provided. It serves as a reservoir for storing first-aid kits, tools and other useful items. On the rear of the frame, you can mount an additional fuel tank with a capacity of 5-7 liters.
How to make a do-it-yourself air suspension from a motorcycle?
The rear-wheel drive of the unit in question is very simple in design and simple to manufacture. The main thing is to take into account the location of the axle shafts and the load on them when assembling the part. In this regard, the yoke should be welded after the assembly of the main unit. As axial elements, analogues from GAZ-69 or 21 are suitable.
If mounting of disc wheels is provided, it is better to use special studs, and connect the axis to the disc using a special flange. Do-it-yourself snowmobiles on a pneumatic ride will also require a cardan tube with suitable bearings with a diameter of 76 mm. Each axis will rotate independently, which will ensure reliable and practical operation of the chassis of the unit.
