Homemade trailer for a car: manufacturing, registration

If you have a car, then you probably quite often face the need to transport all kinds of cargo. In this case, you can not do without the use of a light trailer. It, of course, can be purchased in a store of the corresponding goods, however such construction is possible to make independently.

Work on the frame

A self-made trailer, like a factory-type model, must have a frame that is the basis of the design. Its rigidity and strength will determine the longevity of the trailer. In order to ensure greater reliability, it is recommended to use elements that will be interconnected by welding. Begin work is necessary with the definition of the dimensions of the described element, or rather, the width and length. The size will be determined by the outer edges of the constituent skeleton. In order to determine the final width of the frame, the thickness of one wall multiplied by 2 should be added to the distance between the inner sides of the side walls. If the frame is placed between the wheels, rather than above them, the gap between the bolt and the tire should be taken into account.

If you decide to make a self-made trailer, then after determining the dimensions, you should sample the frame. To do this, the metal profile needs to be spread out on the surface, observing the perpendicularity between the components. Elements must be joined together by clamps. In parallel, you should check the form, for this, using a tape measure the diagonal of the received rectangle is measured. Values should be equal to each other, deviations can be from 2 to 5%. The design must have an edge of rigidity, because the square and the rectangle are unstable structures.

Connection of the trailer with the vehicle

A self-made trailer must have a chain ball. To perform this element, remember that the shorter length of the connecting part indicates a quick response when driving. Even a slight lateral turn of the driving wheels will cause the trailer to drift sharply. This can cause damage to the load and its fall. Making a self-made trailer, you need to choose the optimal length - in the range from 1.5 to 2.5 cm. When choosing a material, it is recommended to use steel pipes of square cross-section that will form the basis of the frame and connections. For the last element you need pipes in the amount of 3 pieces. Connect the frame to the pipe by welding, and for higher strength it is recommended to make reinforcement by means of corners. Before welding, the master must try on the elements so that the coupling is made along the axis of the structure. When homemade trailers are made for a car, at the same stage, a safety rope must be installed, which can be replaced with a chain. If there is a desire, then in the coupling area it is possible to install a folding wheel for the comfortable transportation of a trailer without a vehicle.

Installing the coupling

Homemade trailers for a car must have a coupling that can be installed with welding or bolts. Before the final fixation of this component to the frame, it is necessary to check the coincidence of the dimensions of the frame tubes with the slots of the trough. The latter should not be larger than the width of the pipe, the oversize may be a maximum of 5 millimeters. A welded joint can provide excellent strength, but if damaged, the dismantling will involve the use of a gas burner. The strength of the connection with a bolt is smaller. Bolts should be used, which belong to the eighth class of strength. Less strong will not be able to withstand the effort of cutting. For the connection, you need to prepare two bolts, use a larger amount is not worth it, as this will help to loosen the frame element, as well as the clutch due to the holes for fastening.

Work on the axis

Before registering a self-made trailer, it must be fully prepared for operation. There is a rule that the trailer axle is located at a distance of 40% of the length of the structure from the rear. After you can measure the distance, you must indicate the location of the axis. You can install it by placing the frame on the surface. Use this when you need two 4x4 blocks, while the spindle should hang freely. In the intended place of mounting the axis from the surface of the frame, you need to remove the paint. The step between the bushings should be divided into two, the resulting mark is marked on the surface.

A homemade trailer for a motoblock can be manufactured using the same technology, but the dimensions will be much smaller. In order to check the dimensions, you need to again measure the width of the frame. After that, the wizard can start the final installation. Elements are joined together by welding. It is recommended to use a spring-cushion suspension for the reason that it guarantees more impressive softness, although it differs insignificant strength.

Work on stabilizing jacks

When a self-made trailer is made by hand, it is important to ensure the horizontal position of the structure. The corners of the frame are the most suitable variant. It is possible to install only on one side of the structure. If you consider the device in terms of lift, then it is recommended to use a screw mechanism. It can also be used to replace the wheel.

Summarizing

Homemade trailer for motoblock, as for a car, will be able to expand your capabilities. The latter option can be used to transport cargo, no matter what configuration they have. At the same time, there is absolutely no risk of damaging the machine. Despite the fact that the trailer can have its own specific features, the recommendations given above are common to all options. If there is a desire, a self-made trailer for a boat or for a car can be equipped with a braking system, as well as lighting. However, specialists recommend recommending these issues to professionals.

Trailer registration

If you are thinking about how to make a trailer, then you should be interested in the task of registering it. The design must undergo an examination, what the All-Russian Society of Motorists does, VOA abbreviated. Each region has its own society. To pass the examination it is necessary to make sure that the device corresponds to the existing GOST. You can familiarize yourself with state standards in GOST 37.001. 220-80. Before registering a self-made trailer, you should be aware that the above standard applies to all types of trailers that are intended for towing by minibuses, as well as by cars on the roads of the common network. The standard does not apply to devices designed before the approval of the technical specifications of the standard.

Conclusion

Before you start making a trailer, you should familiarize yourself with state standards, so that you do not have to rework the structure. The weight of the device must not be more than the manufacturer authorized. The weight should not exceed the curb weight of the car. This figure is 1800 kilograms. The length of the device should not be more than 1.5 times the length of the car or a limit of 8 meters. These requirements must be taken into account at the design stage of the trailer, otherwise the use of the construction will be impossible.
