Description

DESCRIPTION HYDRAULIC KING PIN Technical Field Present invention; It is related to the king pin for connecting the trailer and trailer connections of tow vehicles to the vehicle. The invention is particularly related to the hydraulic king pin, which enables the trailer and trailer connections of tow vehicles to be made with the king pin that works with the hydraulic system attached to the vehicle. Description of the State of the Art The king pin used in the connection of tow vehicles and trailer is fixed on the trailer. The trailer tray is attached to the towing vehicle and has a mechanical lock system on it. The tow vehicle reverses to the trailer and the king pin engages the trailer table. The locking process is done by slightly accelerating the vehicle. The trailer presses on the table, and as a result of the lubrication of the table with grease during turns, abrasion of the table surface occurs. In this case, the problems experienced can be summarized as follows: In this system, there are problems with the lock not fitting. Trailer crashes occur. Since there is no ball mechanism, friction is high. Some parts of the vehicle may be damaged due to hitting. There is a need to develop new techniques to eliminate all these problems. In application number TR 2006/01043, a double tension wedge assembly for engaging the front axle king pin is described. The assembly includes an axle beam defining the hub at one end. However, there is no solution to the problems experienced in the king pin explained above, and a mechanism has been described to clamp the front axle king pin. In conclusion; New technical developments that enable the connection to be made without the knocking process that occurs when the trailer is attached to the trailer tractor and without being exposed to excessive impact during the hitching process of the tow vehicle are becoming mandatory. Explanation of the Purposes of the Invention Based on the known state of the technique, the purpose of the invention is to develop a hydraulic king pin that eliminates the drawbacks in existing structures. Another purpose of the invention is to enable the trailer connections of tow vehicles to be made with the king pin that works with the hydraulic system attached to the vehicle. Another purpose of the invention is to avoid the impacting process that occurs when the trailer is attached to the trailer and to prevent the tow vehicle from being exposed to excessive impact during the installation process. Another purpose of the invention is to prevent trailers and trailers from falling down by eliminating the problem of locks not fitting. Another purpose of the invention is to reduce the friction between the trailer and the table since it is a ball-bearing mechanism. In order to achieve the mentioned objectives, the hydraulic king pin has been developed, providing technical advantages by overcoming important technical problems. Explanation of Figures Figure-1; It is a drawing of a representative application of the invention. Reference Numbers 1 Connection plate 6 Locking mechanism 2 Ball mechanism 7 Locking cable 3 Trailer 8 Locking spring 4 King pin 9 Hydraulic piston Button Detailed Explanation of the Invention The invention is based on the hydraulic system-operated king pin (4) of the trailer and trailer (3) connections of the tow vehicles attached to the vehicle. It is related to the hydraulic king pin (4) system that allows it to be done with . The trailer (3), which is normally attached to the towing vehicle, is attached to the trailer (3) by applying the built-in mechanism (2) into the trailer connection table (1). The king pin (4) connected to the hydraulic piston (9) is mounted on the towing vehicle, corresponding to the center of the trailer (3) connection plate (1). When the vehicle goes under the trailer (3) and reaches the connection point, the connection plate (1) on the trailer (3) contacts the button (5) on the vehicle and moves the hydraulic piston (9). The king pin (4) moving upwards enters the connection plate (1) attached to the trailer (3) and the hydraulic piston (9) stops when the locking mechanism (6) is activated. When the connection is desired to be removed, when the unlock button (5) is pressed, the locks lock, and after the locking mechanism (6) is opened, the hydraulic piston (9) pulls the king pin (4) backwards, separating the trailer (3) from the vehicle. There is a locking cable (7) and locking spring (8) on the locking mechanism (6). It is possible to connect the trailer (3) of the towing vehicles with the king pin (4) that works with the hydraulic system attached to the vehicle. Thanks to the king pin (4), which works with the hydraulic system, it is ensured that the trailer (3) is not subjected to any knocking process while attaching it to the trailer tractor and that it is not exposed to excessive impact during the hitching process of the towing vehicle. By eliminating the problem of the locking mechanism (6) not being seated, the trailer (3) and trailer falling are prevented. Since there is a ball mechanism (2), friction is reduced between the trailer, trailer (3) and connection plate (1). The invention is related to the king pin (4) system for connecting the trailer and trailer (3) connections of towing vehicles to the vehicle, and its feature is; The king pin (4) connected to the hydraulic piston (9) in a way that coincides with the center of the trailer (3) connection table (1) on the tow vehicle, which enables the trailer and trailer (3) connections of the tow vehicles to be made with the king pin (4) that works with the hydraulic system attached to the vehicle. ), when the vehicle goes under the trailer (3), when it reaches the connection point, when the connection plate (1) on the trailer (3) touches the button (5) on the vehicle, it is activated and is deactivated when the locking mechanism (6) is activated by pushing the king pin (4) up. It is characterized by the hydraulic king pin (4) system containing the hydraulic piston (9). The trailer contains a ball mechanism (2) between the connection plate (1) and the plate on the towing vehicle in order to reduce the friction between the trailer (3) and the connection plate (1). The connection plate (1) on the trailer (3) contains a king pin (4) that works with hydraulic effect. The king pin (4) connected to the hydraulic piston (9) in a way that coincides with the center of the trailer (3) connection plate (1) on the tow vehicle; when the vehicle goes under the trailer (3) and reaches the connection point, the connection plate (1) located on the trailer (3) When the king pin (4), which moves upwards by touching the button (5) on the vehicle and moving the hydraulic piston (9), enters the connection plate (1) attached to the trailer (3) and the locking mechanism (6) is activated, the hydraulic piston (9) ) includes a deactivated mechanism. When the connection between the towing vehicle and the trailer (3) is desired to be removed, the locks contain a hydraulic piston (9) that allows the trailer (3) to be separated from the vehicle by pulling the king pin (4) backwards when the locking mechanism (6) is opened when the unlocking button (5) is pressed. It contains a locking crescent (7) and locking spring (8) on the locking mechanism (6) that works together with the hydraulic king pin (4). Connection plate (1) on the trailer (3), hydraulic king pin (4) and locking mechanism (6) on the connection table (1), hydraulic piston (9) pushing up the king pin (4) on the plate on the towing vehicle, hydraulic piston There is a button (5) on the towing vehicle or on the trailer (3) to activate the (9), and a locking and unlocking button (for locking with the locking mechanism (6) by pushing the king pin (4) of the hydraulic piston (9) and opening with the reverse movement). 5) includes.
