You will need
- - tubes, profiles and angles;
- - welding machine;
- - components and assemblies from mopeds and motorcycles;
- - additional equipment.
On a sheet of paper make a drawing or sketch of the future of ATV. Consider which items you will do yourself and which you will buy. In the drawing, try as much as possible validly to draw the relative placement of all components and assemblies and reassemble.
The frame of the ATV weld from square profile pipes of circular cross-section and corners. If possible, try to use the elements and fragments of frames of motorcycles, their tubes have a high strength. Water pipes do not use. Don't forget to weld the mounting brackets all components and assemblies.
The engine install and securely mount to the frame. For the first homemade ATV pick up the engine from a moped. The motor shaft connect to gear the rear axle by means of a chain transmission. Controls power unit install on the steering wheel. On the frame attach pedals and control levers.
The power supply system and ignition use the same moped engine. To further equip their reasonable modifications. Fuel tank select a motorcycle, as many things as possible. The ignition system is mandatory to equip the battery.
As front and rear axle will fit units from sidecars and cargo scooters. They almost require no rework, except for the hubs for the new wheels. For the manufacture of suspension shock absorbers use a spring from a Japanese scooter.
The steering is run using two rods, which would rotate the front wheels. Brake lever pull rod, connect with the transmission brake, a staff mounted on the sprocket of the rear axle "Tula 200".
The outer panels of the ATV manufacture of an optical fiber. First of all, make a wooden or clay discs, and then they vilate panel. Before installing them on the bike adjust them to each other, sand and paint. Individual parts of the body take from the production machines.
Advice 2: How to make a homemade motor
Motor is a device that converts any form of energy into mechanical energy. The first electric motor was invented in 1834 by the Russian scientist B. S. Jacobi. Since there are many varieties of electric motors, but today many people want to do it yourself and improve the design of the engine.
You will need
- - vibration alert of the mobile phone;
- - drill;
- - copper wire;
- - fluorine;
- - microchip Allegro А1442.
To not buy magnet specially for the stator, use a vibrator old mobile phone. Hold the eccentric in a Vice and carefully, with the awl squeeze the shaft. The next step will be the release of the brush unit. Pry the same pain bruising on the body and clear the site. You can see the magnet. To it out again, use the drill bit that fits the diameter.
Lay the case on a hard surface and slightly tap on the drill the magnet itself will fall. In the same way to get rid of the glued sleeve, which is not needed.
The role of the shaft, use a drill, because they are more durable and resistant to bending. If the inner diameter of the magnet is larger, and the shaft it's loose, wrap it in copper wire of the required thickness. Thus you increase the diameter of the shaft itself in place of its contact with the rotor.
That the design was not scrolled, the method of resistance welding weld the wire to the part. Now connect the shaft with the rotor and fill the space between it and the magnet special super-glue.
For the manufacture of bushings, use the PTFE. Drill through the sheet hole diameter of 0.3 mm and bring the bushing to the similarity of the tube. To the shaft to move freely through it, grind it to the desired diameter. Thus you will get rid of friction.
Now wind the coil. For convenience make on a lathe frame of required size on which the wrap 60 turns. For this you will need about 90 cm of wire.
Soak the coil with glue without removing it from the frame and gluing it to the latter. It is easy to perform only by using a microscope. Make 2 such windings and glue them, causing a minimal amount of glue between winding and bushing.
Solder one end of each of the windings to get one, but with two conclusions, which at the end of the solder to microchip Allegro А1442.
When welding the main thing is to correctly adjust the device. After all, if the voltage or the capacitance of the capacitor will be very high, the wire will not stick and will start to evaporate, leaving microcrater reducing the strength of the shaft.
To fill the space between the magnet and the shaft, use a special transparent adhesive which does not leave a white residue after drying.
