Trailers for passenger cars, turning them into a small truck, particularly popular with rural residents and owners of summer cottages. Naturally they greatly facilitate the delivery of a wide variety of goods – sand and peat, sand and manure, bricks and gravel. It is a pity that load and unload their accounts entirely by hand – with a shovel. Offer readers the trailer-truck with tipper body. Having made yourself this, you can get rid of the problems when unloading.
It seems that there is no need to describe in detail the design itself – it is fairly traditional also repeatedly told on the pages of “Model construction”. And yet to begin – a few words about the structure of the trailer.
Its frame is welded from steel tubes of square section 40×40 mm, bridge from motorized С3Д using prinovozemelsky shock absorbers of the motorcycle “Ural”. To the frame bridge secured with braces, are also welded from square tubes.
The trailer has a standard ball coupling device is designed for use ball with a diameter of 50 mm.
Trailer with tipping body:
1 hitch; 2 – a spare wheel; 3 – retainer; 4,7,10 – body side; 5 – the splash guard; 6 – warning light; 8 – latch; 9 – coupling; 11 – wheel, 12 – side member of the body; 13 – fitting of the lifting device; 14 – tool tray spare wheel; 15 – frame of the trailer; 16 – hinge body
A lifting mechanism (A transport position of the body; B – position of the body when unloading):
1 – connecting hose; 2 – fitting of the lifting device; 3 – supporting base; 4 – ring; 5 – pneumatic chambers; 6 – case
Connection diagram pneumatic chambers:
1 – camera; 2 – threaded pipe; 3 – nut; 4 – washer
The scheme of fastening of the fitting of the lifting device:
1 – case; 2 – pneumatic chamber; 3 – angled ring; 4 – nut; 5 – washer; 6 – a support platform; 7 – fitting of the lifting device; 8 – connecting pipe; 9 – clamp
1 hitch; 2 – longeron (steel pipe 40×40); 3 – ear locking device; 4 – the hinge of the body; 5 – a back brace; 6 – front-strut; 7 – wheel; 8 – rear cross member; 9 – torsion bar suspension bridge; 10 – front cross member; 11 – bolts, nuts and washers attaching front brace; 12 – bolts, nuts and washers of fastening of the bridge; 13, 14 – connecting clamps
Body assembled from panels, each of which has a frame of steel angles with dimensions of 30×30 mm and a cladding made of plywood with thickness 12 mm bolts M6 nuts. To the bottom are attached to two longitudinal members of timber section 120×30 mm. Mount body to the frame with a hinge, the mating parts of which are welded to the frame and is bolted to the side members; the front part has a locking mechanism that resembles an ordinary latch, which eliminates the tipping during movement.
Now about the main thing – the design of the lifting device. It is pneumatic, driven from the exhaust system of the engine. Under the body, between the spars there are three inner tube in case of durable fabric is canvas or synthetic canvas, attached with M5 screws to the rings of a steel angle on the underside and on the frame. All the cameras are connected by threaded connections, nuts, gaskets and washers, and screwed to the bottom fitting, curved in the form of the letter “L” which is a rubber hose. To raise the body, you need the second hose end to put on the exhaust pipe of a vehicle towing and “add gas”. Two or three minutes -and the body will rise. To lower the body enough to remove the hose from the exhaust pipe.
