Coupling and coupling head: What is what and what they happen. Coupling device for a passenger trailer from a to v Molding method involves three types of devices

Hello, dear friends! Many of you are going to install a hopper on the car to increase its freight opportunities. Therefore, I recommend to find out, what is the coupling head and what is a coupling device. Two concepts relative to which there are many disputes, discussions and conversations.

I will try to tell you in detail about each device and help you in choosing.

Coupling devices

To be more accurate, then traction-hp. Do not forget about the sedelno-coupling mechanisms, which are also used to tow the goods. Only they are relevant for tractors, that is, large trucks For transportation of containers and other trailers. There are also trailed devices for a motoblock, which is also relevant for owners of country sites. But we turn to the main topic of the conversation.

We are also interested in a traction-hitch version of the device (TSU). We use them for a passenger car. But what is this abrakadabra? Under this intricate name hid the motherboard usual. Yes, it is correct to call it a traction-coupling device, although in fact everyone is accustomed to the simple concept of a hopper.

Such TSU uses popularity:

• Bosal;
• Leader plus;
• Trailer;
• Thule, etc.

Planning to buy them and install their own cars of your own car, I would recommend choosing high-quality products that will serve not one season.

TSS used for clutch with different species trailers. With their help, we take several bags of potatoes with the cottages, we independently transport building materials and use for different other tasks, saving money for freight services. He put him on the Renault Duster or on the Niva, and do not know the problems. At the same time, the salon or the trunk is not necessary.

But TSU is different. Some are calculated on the carrying capacity of 3500 kg of the trailer installed (this, by the way, the maximum load for passenger cars), And others have a couple of times lower. This parameter imposes weight limits that can withstand an element.

Constructively TSS consist of two elements:

• cross;
• ball assembly (fixed on the beam).

There are three varieties of this device, each of which has its own characteristics and functions:

• welded;
• removable;
• flange.

Let's figure out who is who. Welded TSS have high reliability indicators, but you cannot disconnect them. That is, the hook will constantly attend the car. Previously, it was relevant and distributed. But now there are alternative solutions in the form of removable and flange hoppers.

Removable are easily removed as needed. Although it is so clear from the title. But they cost more than welded. According to reliability and strength indicators when choosing a qualitative product of claims for removable mechanisms.

Flange TSS are mounted on a special, pre-prepared platform. This must be foreseen before installing. Although I would call them an optimal solution in the contemporary automotive world and what is happening on the roads. But choose in any case to you.

The price of them is different, as well as quality, reliability, durability. You should buy only certified devices. They are manufactured according to the applicable official standards, which guarantees compliance with the selected trailer and coupling head.

That's so smoothly we go to the topic of coupling heads. And you did not notice.

Coupling heads

It is logical that TSU and coupped heads somehow connected with each other. But how?

Imagine that you have a new or old welded or removable sample. This pork must be connected to your trailer. But you will not just throw the hook and go. Nothing good will not come out of such a trip. History It clearly showed when the first prototypes of hoppers and car trailers appeared.

This entailed the creation of a lock coupling device, that is, coupped heads. They serve to ensure a safe and reliable compound of the hook with a trailer. Located a lock on the trailer itself (on Dyshle).

To the number of sought-after SG (coupling heads) I would take:

• Alko knott;
• Choooyo;
• WINTERHOFF.

But before buying them, we will study key features devices.

Modern locking device for trailers or just the lock consists of three components:

• detachable coupling mechanism;
• depreciation system;
• fasteners.

The first element serves directly for the connection between the hook and the trailer for the machine. If the diameter of the ball is 50 mm or you have a diameter of 60 mm, then the sizes of the coupling head must be appropriate.

Coupling heads produce different shapes, and therefore they can easily connect with profile and round pipes, perfectly under the ball. Differ in diameter, cross section. That is, it is not difficult to choose a cross section of 60 × 60 mm. Everything is standardized, and therefore strictly matches each other.

Depreciation elements are present here to extinguish the forces acting on the car with sharp braking and jerks. If the depreciation device is missing, the probability of the emergency breakdown of the entire trailer and at the same time installed on the carbon machine (hitch, you remember).

The role of fasteners extremely clear, as they are responsible for the simplicity and reliability of the connection. Heads differ from themselves depending on what trailer they are intended. For example, under the trailers for passenger cars, they are developing under less loads, for trucks the calculation is made under the heavier designs.

If you bought on big SUV The passenger trailer, it will probably be too low. This is due to the different height of the installation of the Farkop on the car and the jeep. But here you will help the simpler. With it, the height is adjusted and the optimal ratio of the levels between the hitch and the coupling head is achieved.

You can purchase hooks from us. They cost about 1 thousand rubles. The range is big, which will allow you to choose the optimal model for your car. If necessary, we will help you decide on the choice, answering the questions you are interested in.

Features of production and operation

Do not forget that the big weight of the cargo behind the car carries a potential threat. Especially for this, there is a brake on modern trailers. When you brake, the trailer starts to put pressure on the car, pushing it. It's like in a minibus, when the driver slows down sharply, you seem to be kept smoothly, but the other person falls on you. There is nothing nice and safe here.

Therefore, when transporting a large amount of cargo on tractors or even passenger cars, The presence of an inertial brake on the trailer will help you. How it works? When braking, the power of inertia acts on the trailer, which rolls onto the car itself. This force is proportional to a slowdown. The force affects the coupling head, pressing it, and transmits the effort to the brake mechanisms of your trailer. This uses a system of hydraulic or mechanical brakes. This reduces the risk of trailer risk, increases the efficiency and safety of braking while maintaining stability on the road.

As part of the production of trailers, they are checked on special stands using a loader and auxiliary mechanisms. Without it, the design cannot be allowed to sell.

Actively exploiting the hook and the trailer itself with a coupling head, strongly recommend always to have a remkomplekt. He can come in handy on the way, going to the long road. Who knows, maybe you are traveling to your parents in the village to collect the harvest of potatoes on your cottage to win the bathhouse, along the way, loading a ton of wood in the trailer.

When it comes to trailers, novice motorists confidently discuss the issues of lifting capacity and maneuverability. But the issues of the traction and coupling device put on a dead end due to the definition of the concept. Whether this is a coupling device for passenger trailer, whether the trailer hitch head, and maybe drawing is a hitch?!

The benefit of acquiring a branded headquart for the car is understandable. What is a TSU (a traction coupling device) or a hook - this is a hook with a metal ball, sticking below the bumper, to throw the coupling head on it, installed at the end of the direct or V-shaped trailer breath. When there is a need for the shipment of cargo, uncomprepresented to the salon or trunk, the choice of the trailer is accompanied by questions about the Farkop. After all, depending on the attachment, the permissible load on the car's frame is calculated. Of course, the masses are in certificates and on the back of the hood. But what to do if the hitch is not installed?

Definitely:

• Look for a suitable or native brand;
• In the absence of making to order or independently.

What is a traction coupling device

In practice, two types of TSU took place in Russia:

The advantage of this design is the possibility of equipping the trailer brake systemwhich will work on the means of transmitting mechanical oscillations through the ball into the coupling head and ensure the leveling of high-speed drops on the road: inhibits the car, the inertia trailer presses the lever to the ball, turn on the brakes.

Homemade TSUs are trying to fit into specific destination. Otherwise it is possible to prohibit operation. There are many models in the market. All of them differ:

• By weight classification;
• In design;
• Fastening method;
• The features of the attachment of electricians.

Towing with non-standard values \u200b\u200bcan lead to poor consequences. Therefore, the classification of hoppers begins with weight load. Compliance with its group will provide long viability.

1. For passenger cars with a permissible mass of the trailer of 1.5 tons;
2. For universal minivans with a similar value to 2.5 tons;
3. For minibuses, SUVs up to 3.5 tons.

TSA Classification:

European design. The difference from domestic is the size of the ball, which is marked with inches:

• 1-7/8 is 47.6 mm;
• 2 is 50, 8 mm;
• 2-5 / 16 - 58.7 mm.

American design. This is a bit different story. They have the form of a quadrugina mine, which inserts a drawing tip with constipation in the form of a hook-shaped handle.

The method of attachment involves three types of devices:

Factory classification:

The traction-hitch is a meeting place for automotive electricians and trailed. A socket with 7, 13 or 15 contacts is usually mounted on the hinge, and the trailer wiring involves a similar plug. It happens, the fork and socket turn out to be with various options Contacts. The advance selection of the trailer with the desired pinout will exclude the problem. But if this happened, an adapter comes to the rescue.
Manufacturers of hoppers, offering their products to the mass consumer, are responsible for the quality of the material and the resistance of the elements in the assembly, which can be checked only in the factory conditions. The requirements of OST 37.001.299 regulate the characteristics. The handicrafts of the headquarters live and successfully disguise under the original samples. Well, if the master is known for the weight distribution formula relative to the car body and installation of fasteners, but no one guarantees the reliability of the metal.

How to install Pharkop.

Montage of a headquard on a car

TSU is attached to the frame or body body. The bumper is usually removed and its role is getting the main trailer beam. In some embodiments, you have to drill a spar and install mortgage plates. But the installation of the native landarkop is simple. If the manufacturer of the car has provided a place of installation, holes and other items for installing a headquart, and there is a document (as a rule, this is a certificate when buying) with the characteristics of the original device, then the independent installation is completely legal and logical. The service will suggest a certain price. This will pay off if the drilling of additional holes or the installation is not a native headquart, but suitable according to the characteristics. The service will issue a written conclusion on the compliance.

The state of the ball and the TSU itself requires a constant verification for:

• Promoted, torn nuts or bolts (grover prevents spinning, but not disruption);
• Bowl lubricants;
• Clean outlets;
• Welded seams.

The ball is experiencing critical loads, susceptible to wear. I need to measure the diameter every 1-1.5 thousand km of mileage.

Manufacturers of traction coupling devices

Finally, you can bring a list of well-known manufacturers of TSS:

• Bosal - 200 samples for passenger cars and trucks from Belgium;
• Brink - leading position from Holland;
• VFM - Russian association under the Flag of the company Bosal;
• Westfalia is a major German firm. More than 800 items;
• ARAGON - Spanish leader;
• Hiddenhitch - North American company;
• AVTOS - Russian company produces trailers and headquars;
• Baltex is a domestic company from St. Petersburg.

Video review Bosal Farkopov

When the picture is clear, you should not waste time and invent what is already in best option. A common approach to solving the carriage of cargo and a literate mounting of the Factory will definitely lead to success. And lovers of inventions should at least navigate the owners of golden hands.

The best offer is the headquarks on the car, our online store visitors can choose and buy a hitch from the presented range or order the manufacture of the required TSU.

Recently, such products, as higrants, are in great demand for almost all car owners. This is especially true for the owners of SUVs, which practically do not pose a ride without this device, since jeeps are considered excellent traction horses due to the special design of the transmission. There are quite a few life situations in which the presence of a row on a car is simply necessary: \u200b\u200bfrom effective protection of the car from the blow from behind and to solve such a task, like pulling the car from the cuvette or transportation of any cargo.

Types of suggested Farcupov

Currently, Factory manufacturers offer consumers several types of traction coupling devices:

Farca Conditionally removable - the hook is fastened with two bolts and is most common, has a type of ball a;

The hook is fast-release - has a removable hook, which is easy to install and remove, has a type of ball c;

Flange hook - has a forged hook and fastened on two or four bolts, has a type of ball F or G;

Welded hook - has a hook with a rigid fixed fastening, rarely occurs, has a type of ball H.

The most popular and in demand is the TSU of the first type due to the simplicity of the design and affordable cost. Its constant availability is effective protection rear bumper and the opportunity for trouble-free transportation of goods.

Choosing a TSU should take into account the fact that the headquarters from European producers differ from domestic analogues. This implies the features of the design of the plug outlet and the diameter of such an element like a ball. Right choice Couplings for the connection will provide not only a steady matching unit, but also a reliable electrical connection.

All Parkopes presented in our online store, which you can at the most attractive cost, have certificates and documents, which confirms their originality and quality. In addition to the sale of TSU, our company offers a service - installing a headquart with a guarantee.
