Description

TARIFNAME Rampa çekis destek sistemi Teknik Alan Bulus; büyük ebatli, agir yüklerin nakliyesinde kullanilan, römork veya treyler olarak adlandirilan çekis destek sistemleri ile ilgilidir. Teknigin Bilinen Durumu Treyler, motorlu bir tasit tarafindan çekilen ve tasiyacagi yükün özelliklerine has bir sekilde tasarlanip imal edilen en az bir dingili ve çekildigi tasita çeki oku, döner tabla, kanca vb. adlarla tanimlanan bir baglanti aygiti araciligi ile baglanan yük tasima amaçli karayolu tasit aracidir. Hareket eden bir treylerin hizini kademeli olarak azaltmak veya tasiti tamamen durdurmak veya tasit duruyorken, hareketini önlemek için kullanilan parçalarin birlesimine fren sistemi denmektedir. Mevcut durumda bir treyler sasisinin tekerlekler ile baglantisi dingiller ile saglanir. Tekerleklerin merkezinden geçen ve tasitin altina enlemesine yerlestirilmis metal çubuga dingil denmektedir. Dingil kaldirma, kullanim amacina göre aracin dingil veya dingillerinin bagli oldugu Iastiklerin zemin ile olan temasini kesmeye veya bagli oldugu Iastiklere yük aktarimini kesmeye yarayan bir özelliktir. Otomatik dingil kaldirma sistemleri sürücü insiyatifinden bagimsiz olarak aracin bos ve yüklü durumlarina göre devreye giren veya devreden çikan bir dingil kaldirma sistemidir. Bu dingil kaldirma sisteminin uygulandigi araçlarda sürüs yardimi fonksiyonlari da standart olarak sunulmaktadir. 97/27/AT yönetmeligi geregince dingil kaldirma sisteminin sürücü tercihinden bagimsiz olarak devreye girmesi, sistemin disaridan müdahalelere karsi korunmus olmasi Sürüs yardimi fonksiyonu dingillerin tümünün yerde oldugu yüklü durumlarda tercihe göre kabinden veya treyler üzerinde devreye alinan bir sistemdir. Bu sayede araç tamamen yüklü iken tahrikli dingile düsen yük miktarini artirilip kaygan zeminlerde veya egimli yollardaki kalkislarda çekicinin harekete geçisi kolaylasir. Sistemin çekici kabininden devreye alinabilmesi için çekici içerisinde genellikle buton kullanilir. Diger bir alternatif ise otomatik olarak çekici elektronik sisteminden ihtiyaç durumunda otomatik olarak gelmesidir. Araç yüklü ve tüm dingiller yerde iken kalkis yardiminin iki veya daha fazla dingilli araçlar için sürüs yönüne göre ilk dingiline konulmasi esastir. Hava yastiklari ise, havali süspansiyon sistemlerinde kullanilir. Her tekerin dingilinde yay yerine hava yastigi bulunur. Hava yastigi, koruyucu bir kap içinde hava ile sisirilmis lastik körükten meydana gelir. Sürüs yardimi bir dingil kapasitesinin %130 yüklenmesine kadar kullanilabilir. Ancak araç yüksek bir hiza çiktiginda (örnegin 30 km/h hizin üstüne çikildiginda) sistem devreden otomatik çikar ve yüklü dingil asagiya iner. Kalkis yardimi ve araçta kullanilmasi gereken buton ile ilgili olarak araçlarin ön panellerinde bir uyari etiketi bulunmaktadir. Bunun sebebi çekici ve treyler sistemlerinde söz konusu sistemin uyumlu bir sekilde çalismamasina sebep olabilecek uyumsuzluk problemleri olmasidir. Çekici treylere gönderdigi sinyal treyler tarafindan desteklenmiyorsa sistem devreye girememektedir. Bununla birlikte sürücü sürüs aninda direksiyon hakimiyetini kaybedebileceginden her durumda rahatça sistemi devreye alamamaktadir. Bu durumdalar da çekici aracin tahrik aksinda çekis kaybi oldugu durumlarda sistem devreye alinamamis olabilmektedir. özeti; "Bulus, çekici aracin tahrik aksi üzerine düsen yükün arttirilarak dik yokuslarda ya da kaygan zeminlerde aracin patinaj yapmasi engellenmek amaciyla, gerekli sistemin çalismasini saglayan baslangiç sinyali olan giris sinyali, yüksek hizlarda sistemin çalismasinin engellenmesi için gerekli olan hiz bilgisi, sistem için gerekli olan basinçli havayi rezerv eden tüp , treyler üzerindeki yükün tasinmasini saglayan arka hava yastigi, orta hava yastigi ve ön hava yastigi, treyler sasisinin yukari asagi yönde hareket etmesini saglayan indirme kaldirma valfi içeren treyler sürüs yardimi sistemi olup; giris sinyali ve hiz bilgisinin birbirine bagli kalmasini saglayan röle, hava yastiklari arasindaki degisim için gerekli olan basinçli havanin aktarilmasi ya da tahliye edilmesini saglayan selenoid valf, selenoid valf için gerekli olan basinçli havayi tasiyan selenoid valf besleme hatti, hava yastiklarinin kapasitesinden fazla açilmasini veya ihtiyaç duyulan deger kadar açilmasini saglayan sinirlandirici, selenoid valften gelen sinyale göre orta hava yastigi ile arka hava yastigini ve ön hava yastigini birbirinden ayiran kesici/ayirici valf, ön hava yastiginin kontrol edilmesini saglayan ön hava yastigi pnömatik besleme/tahliye hatti, arka hava yastiginin kontrol edilmesini saglayan arka hava yastigi pnömatik besleme/tahliye hatti, kesici/ayirici valf için gerekli olan sinyali saglayan kesici/ayirici valf sinyal hatti içermesi ile ilgilidir." seklindedir.

TR TR DESCRIPTION Ramp traction support system Teknik Alan Bulus; It is related to traction support systems called trailers or trailers, which are used in the transportation of large-sized, heavy loads. State of the Art Trailer is a trailer that is pulled by a motor vehicle and has at least one axle designed and manufactured specifically for the characteristics of the load it will carry, and a drawbar, turntable, hook, etc. attached to the vehicle it is pulled by. It is a road vehicle for the purpose of carrying loads, connected through a connection device defined by names. The combination of parts used to gradually reduce the speed of a moving trailer or to stop the vehicle completely or to prevent its movement while the vehicle is stationary is called the braking system. Currently, the connection of a trailer chassis to the wheels is provided by axles. The metal rod passing through the center of the wheels and placed transversely under the vehicle is called an axle. Axle lifting is a feature that serves to break the contact of the tires to which the axle or axles of the vehicle are connected with the ground or to interrupt the load transfer to the tires to which they are connected, depending on the intended use. Automatic axle lifting systems are axle lifting systems that are activated or deactivated depending on the empty and loaded status of the vehicle, regardless of the driver's initiative. Driving assistance functions are also offered as standard in vehicles where this axle lifting system is applied. In accordance with the 97/27/EC directive, the axle lifting system is activated independently of the driver's preference, and the system is protected against external interventions. The driving assistance function is a system that is activated from the cabin or on the trailer in loaded situations where all the axles are on the ground. In this way, the amount of load falling on the driven axle is increased when the vehicle is fully loaded, making it easier for the tow truck to take off on slippery surfaces or sloping roads. In order to activate the system from the tractor cabin, a button is usually used inside the tractor. Another alternative is that the tow truck comes automatically from the electronic system when needed. When the vehicle is loaded and all axles are on the ground, it is essential that the starting aid is placed on the first axle according to the driving direction for vehicles with two or more axles. Airbags are used in air suspension systems. There is an airbag on the axle of each wheel instead of springs. The airbag consists of a rubber bellow inflated with air in a protective container. Driving assistance can be used up to 130% of an axle's capacity. However, when the vehicle reaches a high level (for example, when the speed exceeds 30 km/h), the system is automatically disabled and the loaded axle descends. There is a warning label on the front panel of the vehicles regarding the start-up assist and the button that should be used in the vehicle. The reason for this is that there are incompatibility problems in tractor and trailer systems that may cause the system in question to not work harmoniously. If the signal sent to the tractor trailer is not supported by the trailer, the system cannot be activated. However, since the driver may lose steering control while driving, he cannot easily activate the system in all situations. In these cases, the system may not be activated if there is a loss of traction in the drive axis of the towing vehicle. summary; "The invention is designed to prevent the vehicle from skidding on steep slopes or slippery surfaces by increasing the load on the drive axle of the tow vehicle. The input signal, which is the starting signal that ensures the operation of the necessary system, the speed information required to prevent the system from operating at high speeds, the compressed air required for the system. It is a trailer driving assistance system that includes a reserve tube, a rear airbag, a middle airbag and a front airbag that allows the load on the trailer to be carried, a lowering and lifting valve that allows the trailer chassis to move up and down, a relay that ensures that the input signal and speed information remain connected to each other, Solenoid valve, which allows the transfer or evacuation of the pressurized air required for the change between airbags, solenoid valve supply line, which carries the pressurized air required for the solenoid valve, limiter, which ensures that the airbags are opened beyond their capacity or to the required value, according to the signal from the solenoid valve. breaker/separator valve that separates the middle airbag from the rear airbag and the front airbag, front airbag pneumatic supply/discharge line that allows control of the front airbag, rear airbag pneumatic supply/discharge line that allows control of the rear airbag, breaker/ "It is related to the breaker/separator valve signal line that provides the signal required for the disconnector valve." in the form. As can be seen, the system is related to level control and trailer driving assistance system, and does not mention a structure that can provide a solution to the disadvantages mentioned above. As a result, due to the negativities described above and the inadequacy of existing solutions on the subject, it has become necessary to make a development in the relevant technical field. Purpose of the Invention: The invention aims to introduce a structure with different technical features that brings a new initiative in this field, unlike the structures used in the current technique. The primary purpose of the invention is; It is to prevent loss of traction on the vehicle drive axle of the tractor while the tractor and trailer are passing on an inclined road. The purpose of the invention is to transmit the angle information received by the tilt sensors placed on the trailer of the vehicle to the electronic control unit in order to prevent loss of traction, and to activate the driving assistance system according to the incoming data and the road condition and vehicle speed. Another purpose of the invention is to ensure that the system goes into a passive state and does not work above a determined speed (for example, v = 30 km/h). In order to fulfill the purposes described above, the invention is a traction support system for trailers or trailers used in the transportation of large-sized, heavy loads, and its feature is; o Axle lifting system, which cuts the contact of the tires to which the axle or axles are connected, with the ground, o Trailer tilt sensor, which is located on the trailer and measures the tilt of the trailer, o Speed sensor, which measures the speed of the trailer, o Load measurement sensor, which enables the weight of the trailer or the load on the trailer to be measured, o Trailer It contains an electronic control unit to which the data received from the slope sensor, load measurement sensor and speed sensor are transmitted, and which activates the axle lifting system by detecting whether the vehicle enters the ramp and whether it has difficulty in traction, based on the vehicle speed level and slope information from the data obtained. The structural and characteristic features and all the advantages of the invention will be more clearly understood thanks to the figures given below and the detailed explanation written by making references to these figures, and therefore the evaluation should be made taking these figures and detailed explanation into consideration. Figures to Help Understand the Invention Figure 1 is a general representation of the system that is the subject of the invention. Figure 2 is a representation of the trailer with its axle raised. Figure 3 is a representation of a trailer without a raised axle. Drawings do not necessarily have to be scaled and details that are not necessary to understand the present invention may be omitted. Furthermore, elements that are at least substantially identical or have at least substantially identical functions are designated by the same number. Description of Part References Trailer Tilt Sensor Electronic Control Unit Axle Lifting System Speed Sensor Load Measuring Sensor Detailed Description of the Invention In this detailed description, the preferred embodiments of the invention are explained only for a better understanding of the subject and in a way that does not create any limiting effect. Meet; It is related to traction support systems called trailers or trailers, which are used in the transportation of large-sized, heavy loads. Axle lifting system (3) is the system that cuts the contact of the axle (6) or the tires to which the axles (6) are connected, from the ground. The axle lifting system (3) actively constantly transfers the axle (6) lifting status to the electronic control unit (2). The electronic control unit (2) is the system that controls the system and monitors when the driving assistance system will be activated and deactivated. In the system subject to the invention, a trailer tilt sensor (1) that measures the tilt of the trailer is placed on the trailer. There is also a speed sensor (4) that measures the speed of the trailer and a load measurement sensor (5) that allows the weight of the trailer or the load in the trailer to be measured. When the tow vehicle enters a sloping road, the data received from the trailer tilt sensor (1), load measurement sensor (5) and speed sensor (4) are shared with the electronic control unit (2). The electronic control unit (2) understands that the vehicle has entered the ramp and is experiencing traction problems, based on the low level of vehicle speed and slope information obtained from the data obtained. The data coming from the load measurement sensor (5) is also evaluated and the electronic control unit (2) activates the axle lifting system (3) according to the appropriate weight. In this case, partial or full lifting is done depending on the value of the measured load. In partial lifting, in order to prevent the 130% load rate of the axle capacity from being exceeded, the load is partially lightened without disconnecting the wheels on the liftable axle from the ground. When the driving assistance system is active, the trailer tilt sensor (1), load measurement sensor (5) and speed sensor (4) instantly share information with the electronic control unit (2). When the vehicle reaches a certain level, the system automatically deactivates and the vehicle continues driving. TR TR
