Every owner of the vehicle is obliged to decide on the safety and security of his vehicle. Those who have a garage can, of course, sleep in peace. However, most car dealers have to leave their cars on the street.
The first carjacking was recorded in 1889, and the attackers stole a car from a French baron from his private garage
Today, almost all vehicles are equipped with an alarm. But it is no secret that, despite many existing forms of electronic security systems, almost any car can be stolen. In this aspect, mechanical antitheft may be more reliable. The use of both types of devices is particularly effective.
History of anti-theft systems
With the advent of the first cars in 1886, their happy owners immediately raised the question of how to protect the car from theft. The first hijacking occurred three years later-the attackers stole a Peugeot car from a French baron from his private garage.
Of course, the only way to protect the machine at the end of the nineteenth century was the use of various mechanical anti-theft devices, many of which went in one form or another before our days. Thus, the owners of the time used forks and plugs that blocked the wheels, the steering wheel and the door locks.
The alternative to mechanical anti-theft systems appeared after [ [ World War II]]-electronics
The first pits were hinged, that is, they did not require a special installation. Later, with the development of technology, there were protective systems that were built into the car at factories or in private workshops. Their appearance was associated with relatively high reliability and compactness. The alternative to mechanical anti-theft systems emerged after World War II-electronics were protected.
Types of mechanical anti-theft systems
Mechanical anti-theft systems can be divided into three types: protecting from entering the cabin or subpotic space that prevents movement, blocking the various nodes. Consider each type separately.
So, quite often, cars are equipped with anti-theft protective doors, luggage compartments and bonnet. As a rule, this type of device is equipped already at the plant. The doors of the vehicle shall be protected by the pins through the doors and pillars of the body. The device works in a couple with an immobilizer. The locking mechanism shall be activated when the alarm is activated, and the pins can only be removed if the immobilizer chip is fitted with sufficient access to the vehicle.
There are also devices blocking the state lock mechanism (the latter are more likely to be adapted to certain car models). Such blockers are equipped with an electromagnetic unit and may interact with electronic security devices. For safety reasons (for unobstructed exit of the car in the event of an accident) locking of the doors is carried out only with the ignition off.
Because most of the machines have a bonnet top that can be connected and defused the alarm, mechanical devices protecting the bonnet are used.
The bonnet covers can block either an additional lock or a mechanical device that prevents the permanent lock of the staff. Such a device is generally equipped with a cable in a flexible shell.
There are electromechanical blocs of bonnet. The management of such a device is usually carried out with the help of the immobilizer. In this case, there are no mechanical parts of the machine in the car. Some of this type of design has a built-in electrical device that is blurred when the bonnet is blocked by one of the engine's electrical circuits. According to fire safety requirements, there is a need to duplicate an electron cable with a secret emergency cable.
Among the mechanisms that prevent the movement of the machine, the caravor blocker has the greatest popularity
There's another kind of hood blocker. It is particularly characteristic of the electromechanical device, which is equipped with a cable lock on the bonnet. A running lock simulates a lock or cable failure.
Among the mechanisms that prevent the movement of the machine, the carat blocker has the greatest popularity. The crater may be installed in the rear wheel or four-wheel-drive vehicles. The curator consists of two elements: locking and force. The first one is in the cabin and the other is in the bottom of the car. As you can guess, the power element prevents the rotation of the shaft, which makes the car immobile.
Finally, the most popular anti-eaters are driving the car. There are two types of devices. Some are needed to lock the gearbox, while the other does not allow the steering wheel to be rotated. They shall be installed both in a state and in addition.
To block the carton in the car's car, near the checkpoint, there is a hole in which the probe is inserted. It is equipped with a lock so that it can only be removed if there is a key. If the gearbox is mechanical, the probe prevents the inclusion of all the gear except for the rear. In the automatic gearbox, the pin does not allow to change the Parking mode in which the car will not be able to move. There are also non-hintered structures. Such devices do not allow the transfer of the lever (or the thrust of the gear selection) due to built-in locking mechanisms. The keylock mechanism is opened and closed, and the lock can be on the dashboard or in the console between the front seats.
However, this type of interlock allows a motor vehicle with a manual gearshift to move with the clutch of the clutch.
Almost all modern vehicles are equipped with freezing curators. The engine is connected to the ignition lock. If there is no key lock in the lock, the steering wheel does not allow the steering wheel to turn. The main disadvantage of these devices is the lack of adequate strength. When you turn a blocked rudder, the mechanism can be broken.
Additional hinged locks on the rudder are widely used. They are very simple: the muff that is attached to the steering wheel, and the corkscrew connected to it, which is placed above the dashboard, thus limiting the steering. The mechanism has a lock and is opened with a key.
The design of most mechanical anti-theft systems is quite simple, yet they effectively protect cars from criminals for many years.
