what is it in the car? Photo and purpose
Tow hitch (TSU) is a special towing device designed to securely fasten the trailer to the machine in order to distribute the load as evenly as possible, which is created by inertia and weight. TSU expands the capabilities of the vehicle, as well as ensures the safety and reliability of the transported cargo.
A well-made and installed towbar will not spoil the appearance of the car.
The main function
Some motorists mistakenly believe that the towbar performs an exclusively protective function: they say that in the event of a traffic accident, the device takes on all the force of the impact from behind. It would seem that everything is correct, but why is it strictly forbidden all over the world to drive with a towbar without a trailer? The reason for this is that the vehicle, on the contrary, will be damaged much more if the impact occurred in the towing vehicle, and not in the bumper.
That is why it is recommended to use a removable towbar, so that when traveling without a trailer, you do not expose the “iron horse” to unnecessary danger.
Varieties
All towbars are conditionally divided into the following categories (depending on the method of attaching the ball assembly):
- removable (fixed with locks);
- conditionally removable (fixed with bolts);
- welded;
- end.
Separately, it is worth talking about conditionally removable devices (they are also called flanged). They are fixed on pre-equipped platforms in the rear of the car (mainly a pickup truck) and are fastened with two or four bolts. Such a towbar can also be removed, but this is much more difficult to do than in the case of an ordinary removable one. Flanged devices are extremely reliable, and therefore are used in most cases for transporting heavy and oversized cargo. Moreover, they provide for certain requirements for the car, the main of which is the presence of a frame structure.
As we just said, for safety reasons, the TSU must be removable. Also note that towbars designed for vehicles of different models can differ significantly. So, for domestic, Western and Japanese cars, the hitch points of the tow hitch are completely different, which cannot be ignored when choosing a towbar.
Winemaking
At all stages of production, special technologies and equipment are used. First, a three-dimensional model of the car is created by means of a measuring machine, which is tested in a laboratory under the supervision of government departments.
In mass production, bending machines and high-precision laser cutting mechanisms are used, as well as metal shot blasting using high-quality polyester powder. The production technology must be observed, which is why the quality is controlled literally at every stage of production.
Sultan chose
When choosing a hitch, one should take into account such a parameter as the maximum vertical / horizontal load on the coupling device. In order to correctly calculate this load, you should know the following important points:
- maximum weight of transported goods;
- vehicle brand;
- trailer weight limit;
- type of vehicle equipment;
- kind of hitch on a trailer.
If the load on the towbar exceeds the maximum allowable, not only the coupling device, but also the body of the car itself may be damaged. Moreover, if such a breakdown occurs on the go, it can cause a traffic accident.
In a word, take the choice of a towbar for your car with all seriousness and responsibility.
Never skimp on quality. Give preference only to certified models that have passed all the necessary tests and have been verified by the manufacturer. A durable, high-quality towbar is a guarantee of safety on the road when driving a car with a trailer.
