Most cars and evencomparatively capacious crossover or jeep can not boast too much of a spacious trunk. As a rule, you can put only the most necessary things, and half the space is occupied either by a spare wheel, or a set of tools, a jack and a tow rope. Installing an additional trunk on the roof of the car significantly increases the useful volume, without causing any damage to the appearance of the car. On the contrary, the company trunks look very stylish. However, they are quite expensive.
But with a certain amount of skill and possessioncertain skills it is possible to make and install the trunk on the rails of the car with their own hands. About how to do this and what is required, and will be discussed in this article.
The main purpose of the overtalk trunk
It is obvious that the main function of this element, located on the roof, is the placement of various items necessary for travel or on daily trips.
В отличие от штатного отделения, багажник на railing, made by yourself, or made in the factory, allows you to transport not only additional cargo. With such a simple device as a rail, with or without attached trunk, you can transport long objects (for example, skis) or dimensional goods (bicycles, furniture, etc.).
Installation of the trunk on the regular rails of the car
In those cases where the car was originallyequipped with longitudinal or transverse special external beams, install the trunk on the rails with their own hands is quite simple. If we are talking about the design of factory production, then to each trunk, as a rule, all the necessary fasteners and detailed installation instructions are attached. All that can be needed in these cases is the appropriate wrench and screwdriver.
In addition, often the cargo or special trunk is fixed to the guides and at all without the need to use any tool at all - simply with the help of straps.
However, even if you make the trunk ondo-it-yourself railings, the installation process also does not require any special equipment or tools. Since already in the manufacturing process it is necessary to provide for the presence of fasteners.
Advantages of self-manufacturing
Many motorists tend not to buy this important car accessory, but to make it themselves. This solution gives the car owner a number of obvious advantages:
- Ability to choose the optimal parameters.Making the trunk on the roof of the car on its own, the owner of the car can choose his optimal physical dimensions, satisfying these or other requests and requirements, as well as the geometric shape. This is important from the point of view of maintaining the aerodynamic properties of the car, and from considerations of the ability of the element to perform certain specific tasks. About what variety can have a made trunk on rails with their own hands, a photo of such constructions speak eloquently enough.
- Substantial financial savings.As mentioned above, branded branded rails and trunks for them are quite expensive. In the independent manufacture of the coffer car owner can choose cheaper materials and not use any expensive technology.
- Perfect trunk compatibility with specificby car. Who, if not the owner, knows best of all the features of his car? It is with their account you can independently make such a trunk, which will have the ideal characteristics of the area or volume, as well as carrying capacity. And at the same time have an aesthetic appearance that fully corresponds to the tastes of its owner.
Thus, the desire to make the trunk on the rails with their own hands is understandable.
Especially since this is quite a fascinating creative process.
The main requirements for them
In addition to the parameters of the capacity of the nadkryshnogo element, it must meet certain standards. They primarily concern the following aspects:
- Geometrical dimensions.As a rule, the trunk area is dictated by the analogous parameter of the roof of a particular car model. But many car owners manage to make its edges beyond the perimeter of the roof. It is very important to understand that such a decision can significantly change the position of the center of gravity of the machine and the characteristics of its stability.
- Strength.Even taking into account the fact that the trunk is based on metal structures, its carrying capacity is usually limited to 100-120 kg of load. An increase in this parameter is fraught with a deformation of the car body, a loss of the values of the power characteristics of the car and a decrease in operational and driving safety indicators.
How to make your own trunk on rails
In those car models, where the regular railsnot provided by the factory assembly technology, you can install them on your own. This will require the following set of materials, tools and equipment:
- Комплект специальных боковин, которые можно purchase almost any automotive parts store. The set of sidewalls consists of two pieces, therefore it is more expedient to buy two such sets.
- Metal profiled tube.Choosing round tubing is a fairly common mistake. The rectangular profile provides much higher load stability. It is best to choose a pipe section 15x15 mm and a wall thickness of 2 mm.
- Portable welding machine with the necessary supplies.
- Roulette.
- Grid with 4x4 cm cells.
With such an arsenal, you can safely get to work.
Determining the size of the trunk
The first step is to measure the length and widththe roofs. The geometrical dimensions of the future structure will largely depend on these indicators. It goes without saying that the trunk on the rails ("UAZ Patriot") made with your own hands will be much larger than on the Daewoo Matiz, for example. Based on the measurement results, a profiled tube is cut for the longitudinal and transverse trunk guides.
Cutting and welding
Crossbars for railings sold in specialized automotive stores.
If you can not find a crosslength, they will need to be cut. The set of cross-pieces, as well as sidewalls, consists of two products. For weight distribution on 8 reference points it is best to buy two sets.
The crossbars are attached to the frame, consisting of thethe same profiled pipe and repeating the perimeter of the roof of a particular car, by welding. Thus it turns out the lower base, which should have a trunk on the rails with their own hands (VAZ-2111 or any other model).
Then in the same way performedtop platform. It is very important that both designs are exactly the same size. To fasten the two halves of the trunk with each other is best with the help of the same welding. It is important immediately after the cooling of the metal to clean the welds.
Installation of the structure
Now it only remains to fix the homemade design on the roof of the car.
To do this, use a special cross,which, in turn, are attached to the car body with bolts and nuts. It is best to use 4 such cross-beams - then the design will be strong, reliable and safe. It is not at all superfluous to use rubber, polyurethane or plastic gaskets in the places of fastening and adjoining the elements of the trunk to the car body.
Finishing work
After fixing the homemade item it is necessary to paint it.
This is necessary not only for the trunk toroof rails looked more aesthetically pleasing, but also in order to extend its service life. At the bottom of the bottom of the device it is best to lay the grid with a width of cells of about 4x4 cm. This will make it easy to get rid of snow in winter and fallen leaves - in the fall.
Thus, the creation of the trunk on the railson their own - although quite laborious, but not such a complicated process. Instead, it provides a solution to many problems. For example, an expeditionary trunk for railings made by own hands allows you to take with you on long journeys and tourist trips everything you need without any problems.
The self-made element allows to transport bicycles, skis, construction materials, large and oversized cargoes without the need for additional security measures.
