Daha spesifik olarak mevcut bulus, araç üzerindeki bir burcun ihtiva ettigi sensör tertibati vasitasiyla performansindaki degisimin takip edilerek burcun önceden belirlenmis deplasman (yer degistirme) degeri üzerinde, yine önceden belirlenmis bir sürede ya da kilometrede çalistigi durumlarda burcun kalan ömrüne iliskin uyari veren bir ömür takip ve uyari sistemi ve buna iliskin bir yöntemle ilgilidir. More specifically, the present invention relates to the sensor assembly comprising a bushing on the vehicle. predetermined displacement (displacement) of the bush following the change in performance In cases where the bush operates above its value, again in a predetermined time or kilometer, It is about a life tracking and warning system that gives a warning about the remaining life and a method related to it.
Teknigin Bilinen Durumu Burçlar, motorlu araçlarda süspansiyon parçalarinin araç sasisine baglanti noktalarinda, aracin hareket halinde iken maruz kaldigi titresim ve gürültülerin azaltilmasi ve sistemdeki kararsiz davranislarin telafi edilmesine yönelik, özel olarak tasarlanilarak kullanilan, yapisi ve süspansiyon parçalarina izin verdigi hareket ile araca yoldan gelen gürültü ve titresimleri en aza indirilen ve ayni zamanda süspansiyon parçalarinin serbest hareket etmesine olanak saglayan genellikle kauçuk, kauçuk-metal veya kauçuk-plastik titresim sönümleyici elemanlardir. Ayrica, hidrolik burç adi verilen içerisinde hidrolik bir akiskan içeren ve akiskanin tercihen bir odadan digerine en az bir kanal araciligiyla geçmesine olanak saglayan burç yapilari da mevcuttur. Her ne kadar geleneksel burçlara göre kompleks bir yapiya haiz olsalar da hidrolik burçlar da tüm burçlarin olmazsa olmaz birleseni olan, sönümlemenin tamaminin veya büyük bir kisminin saglandigi kauçuk yapisini içermektedir. State of the Art The bushings are at the connection points of the suspension parts to the vehicle chassis in motor vehicles, Reducing the vibrations and noises it is exposed to while in motion and unstable in the system specially designed and used to compensate for behavior, structure and suspension With the movement it allows, the noise and vibrations coming from the road to the vehicle are minimized and the same usually rubber, which also allows the suspension parts to move freely, rubber-metal or rubber-plastic vibration damping elements. Also called hydraulic bushing at least one channel, preferably from one room to another, containing a hydraulic fluid in it There are also bushing structures that allow it to pass through. Although traditional horoscopes Although they have a complex structure, hydraulic bushings are also an indispensable component of all bushings. which includes the rubber structure, in which all or most of the damping is provided.
Islevleri ve konumlari geregi tüm burçlar sürekli degisen büyüklüklerdeki ve yönlerdeki yükler altinda çalismaktadirlar. Burçlar süspansiyon sisteminde montajinin yapildigi yer ve konuma göre, radyal, ekseneli kardanik ve torsiyonel yönde hareketlere maruz kalirlar. Tekrarli basi (compression) ve çeki (tension) yüklemelerine maruz kalan kauçuk parça sürekli olarak belirli bir noktadan (relaxation point) geçtigi için zamanla isinmakta ve kimyasal baglari zayiflayarak bir müddet sonra kopmaya baslamaktadir. Bunun sonucunda burçlar zaman içerisinde fiziksel ve mekanik degisimlere ugradigindan buna bagli olarak performanslari azalmakta ve bir süre sonra kullanim ömürlerini tamamlamaktadirlar. Due to their functions and positions, all bushings are under loads of varying magnitudes and directions. they are working. Bushings in suspension system, radial, They are exposed to axial cardanic and torsional movements. Repetitive compression and draw The rubber part, which is exposed to (tension) loads, is constantly moving from a certain point (relaxation point). As it passes, it heats up over time and weakens the chemical bonds and starts to break after a while. is starting. As a result, the signs are subject to physical and mechanical changes over time. As it is damaged, their performance decreases accordingly and after a while, their service life decreases. they are completing.
Halihazirda burçlarin standartlarla belirlenmis ömür performansini belirleyen bir kriter veya standart mevcut degildir. Bunun nedeni, burcun yapisinda bulunan kauçuk malzemenin özellikleri, burcun tasarimi ve aracin süspansiyon sistemi üzerinde montajinin yapildigi yer ve konuma göre üzerine gelen yükler vb. birçok unsurun burçlarin ömür performanslarinin belirlenmesinde etkili olmasidir. Bu nedenle her bir burç için çalisma ömrü birbirinden farkli olabilmektedir. A criterion or standard that determines the life performance of the bushings already determined by the standards. not available. The reason for this is the properties of the rubber material in the structure of the bush, according to the design and the place and location where the vehicle is mounted on the suspension system. incoming loads etc. Many factors are effective in determining the life performance of the bushings. This Therefore, the working life for each bushing may be different from each other.
Burç üreticileri burçlarini piyasaya sunmadan önce kuvvet ya da herhangi bir sekil degisikligi altindaki davranisini belirlemek için statik karakterizasyon ve tekrarli yükler altinda düsük frekanslardan yüksek frekanslara kadar ürünlerin elastik, viskoelastik ve sönüm özelliklerinin ortaya konuldugu dinamik karakterizasyon testleri yaparak burçlarin mekanik ve fiziksel özellikleri ile ilgili sonuçlar elde etmektedir. Bununla birlikte bir ya da birden fazla serbestlik derecesinde (yönde) farkli dinamik yükleme kosullarinda yüklere tabi tutularak ürünün fiziksel ve mekanik degisimlerinin izlenerek parçalarin servis ömrü boyunca yani gerçek çalisma kosullarinda nasil davranis sergileyecegini öngörebilmek amaciyla yorulma ve ömür testleri gerçeklestirilmektedir. Ömür testi, ürün fiziksel olarak kirilip tahrip oluncaya kadar devam ettirilirken dayanim testi ürünün belirli bir özellikteki degisimi görülene kadar veya belirlenen bir çevrim tamamlanana kadar devam ettirilmektedir. Before bushing manufacturers put their bushings on the market, they must be subjected to force or any shape change. static characterization and low frequencies under repetitive loads to determine its behavior. The elastic, viscoelastic and damping properties of the products up to high frequencies are revealed. obtain results on mechanical and physical properties of bushings by performing dynamic characterization tests. is doing. However, different dynamics in one or more degrees of freedom (direction) by monitoring the physical and mechanical changes of the product by subjecting it to loads under the loading conditions how the parts will behave during their service life, that is, under real operating conditions. Fatigue and life tests are carried out in order to predict Life test, product physical While the strength test is continued until it breaks and is destroyed, the strength test of the product is It is continued until a change is seen or until a specified cycle is completed.
Yorulma testleri kuvvet ya da deplasman kontrollü yapilabilmektedir. Ürünün kuvvet ya da herhangi bir sekil degisikligi altindaki davranisini belirlemek için statik karakterizasyon testleri yapilarak statik yay sabiti (static stiffness - nesnede birim sekil degisikligi yaratabilmek için gerekli olan kuvvet) degerindeki degisim yani deplasman-kuvvet degisimi incelenmektedir. Bu testler ömür testinden önce ve sonra ya da belirli araliklarla laboratuvar ortaminda yapilmaktadir. Kuvvet ve sekil degisikliginin birbiri ile olan iliskisi kuvvet-deplasman egrisi ile gösterilmektedir. Kuvvet kontrollü yapilan bir testte, kuvvet belirlenen çevrim sayisi boyunca sabit olacagi için parçanin yorulma davranisini incelerken deplasman degisim egrilerinden faydalanilmaktadir. Bu degisim parçanin test sonucunu degerlendirmede tek basina yeterli olmamakla birlikte yarilma, deformasyon baslangici hakkinda bilgi vermektedir. Statik degerdeki degisimi incelemek için; yorulma testinden önce ve sonra parçanin belirlenen parametrelerde statik yay sabiti ölçümü yapilmaktadir. Statik degerlerdeki degisimin fazla olmasi burcun ömür performansinin kötülestigi anlamina gelmektedir. Son olarak parçanin görsel kontrolü yapilarak parçada deformasyon, çatlak, yarilma vb. olup olmadigi kontrol edilerek yorulma test sonucuna karar verilmektedir. Üretilen burçlar piyasaya sunulmadan önce performans degerlendirmesi laboratuvar ortaminda yapilirken halihazirda araç içerisinde kullanilmaya devam eden burçlarin performanslarinin degerlendirilmesi mevcut teknikte görsel kontrollerle saglanmakta ve bunun sonucunda ömürlerini tamamlayip tamamlamadigina yani degistirilip degistirilmeyecegine karar verilmektedir. Burcun kullanim ömrünün sürücü tarafindan tespit edilmesi oldukça zordur. Bahsedilen görsel kontrolü bakim elemani/tamirci gibi konuda uzman bir kisinin yapmasi gerekmektedir. Bu da araç kullanicisi için bir kontrol maliyetini beraberinde getirmektedir. Bu nedenle burçlarin kontrolleri genellikle araçlarin periyodik bakimlari sirasinda gerçeklestirilmektedir. Ancak bu sekilde iki periyodik kontrol arasinda performansi azalan ve/veya kullanim ömrü sona eren burcun tespit edilmesi mümkün olmamaktadir. Fatigue tests can be performed with force or displacement control. Static to determine the behavior of the product under force or any change in shape. static spring constant (static stiffness - unit shape change in the object) by performing characterization tests the change in the value of the force required to create is being examined. These tests are performed before and after the life test or at certain intervals in the laboratory. is done in the environment. Relationship between force and deformation force-displacement curve is shown with. In a force-controlled test, the force is constant throughout the specified number of cycles. When examining the fatigue behavior of the part, the displacement change curves will be are used. This change alone is sufficient to evaluate the test result of the part. Although not, it gives information about the onset of cleavage and deformation. static value to examine the change; Before and after the fatigue test, the static of the part at the determined parameters spring constant is measured. If the change in static values is too much, the life of the sign means worsening performance. Finally, by making a visual control of the part, deformation, crack, splitting etc. in the part. Deciding on the fatigue test result by checking whether are given.

Sadece deplasman ölçerek degil kuvvet ya da ivme ölçerek de ömür takibi yapilarak uyari verilmesi mümkündür.Vehicle (90) speed, road bump etc. Due to various environmental conditions, the signs may appear from time to time, instantaneously or It can temporarily make a displacement movement outside of ± 3mm. However, the present invention parameter value (displacement value for this example) determined by the warning system (80), not every time it exceeds the threshold value (± 3mm displacement for this example), but within a specified It is also provided to give a warning when it exceeds the said threshold value throughout time. Just Giving a warning by monitoring the life by measuring force or acceleration, not by measuring displacement possible.
