A moped is often considered an expensive child’s toy. In fact, many of these two-wheeled machines will be acquired by the youth for purely entertainment purposes. And only a small proportion of mopeds being used as a vehicle for business travel. But if you suddenly have the need to transport any goods — for example, a gas cylinder, a few bags of cement or, in the end, bundles of hay! Can carry it all on a hand truck, while half to two “horses” mess around in the barn!
If desired, any moped to turn into a kind of a truck-trailer, and while he moped undergoes minimal alteration, and retains the ability to perform their regular functions.
Alteration of a moped is to charge him the towing device. It represents, curving of steel pipe with outer Ø 22-25 mm, wall thickness 2-2,5 mm. to Bend the pipe preferably in the bending, filling its pre-dry, sifted sand and warming up during the deformation, the location of the bend with a blowtorch (or pre — horn). The free ends of the tube flattened and drilled holes the diameter of the rear axle of the bike. The tow arc is fixed on the axis of the moped regular nuts on the rear axle and is further supported by two struts from steel strips with a cross-section 3X20 mm, the ends of which are bent in the form of a stirrup and is fixed by screws and nuts with thread M5. Finally, the tow arc is drilled hole Ø 12,2 mm for cardan coupling device.
The trailer-the trailer is a two-wheeled cart, complete with wheels from the moped, a simple suspension system and inertia braking device. The body of the trailer is plywood. For the bottom and sides were used as construction plywood 12 mm thick. the Assembly is made using aluminum profiles “corner” 40X40 mm with a flange width of 3 mm. Very durable and beautiful it turns out body, in which “parts” are located inside and outside; the flanges are firmly tightened to each other and the base, forming a rigid box. Edges of the boards also fringes dural “area” with the strengthening of the wooden rail section 20X20 mm, as shown in the drawings.
In the lower part of the body, on the base are mounted two longitudinal members of the wooden slats section 30X75 mm — they are the strengthening of the bottom; between them are placed damping members — the usual tennis balls. As shown, they are very reliable podruzamevaet body, can withstand a greater load, and their lifespan is practically unlimited.
The frame of the trailer-trailer is very simple and is a T-shaped structure welded from two steel pipes with Ø of 30 mm and a wall thickness of 2.5 mm. In principle, it is possible to use a water pipe, the so — called “inch”. Place of a joint of pipe reinforced by steel triangular gussets from sheet steel with a thickness of 3 mm.
