PRIOR ART Independent suspension systems, one of the critical subsystems of road vehicles, It has been used for more than half a century in buses and military vehicles, as well as in vehicles. finds the field.

Son yillarda özellikle sehirlerarasi yolcu otobüslerinde konfor ve sürüs dinamigi alanindaki üstün özellikleri sayesinde yaygin olarak kullanilan bagimsiz süspansiyon sistemleri, sehir içi otobüs ve midibüslerde de, inis - binis kolayligi açisindan standart hale gelen alçak taban uygulamasina olanak vermesi neticesinde kendine yer bulmaya baslamistir. Bugün sehir içi tasimacilikta kullanilan alçak tabanli otobüslerin ön tekerleklerinde de bagimsiz Süspansiyon sistemleri tercih edilmektedir. In recent years, especially in the field of comfort and driving dynamics in intercity coaches, Independent suspension systems, which are widely used thanks to their superior features, The low floor, which has become standard in buses and midibuses, in terms of getting on and off As a result of allowing its application, it started to find a place for itself. In the city today Independent Suspension on the front wheels of low-floor buses used in transportation systems are preferred.

Bunun yaninda engebeli arazi satlarinda yüksek taban serbestligi ihtiyaci, tekerleklerin birbirinden bagimsiz hareketine olanak saglanmasi neticesinde araç için hayati önem tasiyan tekerlek yol temasinin süreklilik göstermesi, araç performansi ve stabilitesine katkisi sayesinde de tekerlekli askeri araçlarda da bagimsiz süspansiyon sistemleri siklikla kullanilmaktadir. In addition, the need for high floor freedom in rough terrain sales, which is vital for the vehicle as it allows independent movement of each other. Thanks to the continuity of wheel-road contact, its contribution to vehicle performance and stability. Independent suspension systems are also frequently used in wheeled military vehicles.

Günümüzde binek araçlarin çok büyük kisminin ön tekerleklerinde, bazi üst seviye veya spor araçlarin hem ön hem arka tekerleklerinde, sehir içi ve sehirlerarasi yolcu tasimaciliginda kullanilan otobüs ve midibüslerde, askeri araçlarda bagimsiz süspansiyon sistemlerinin çesitli türleri kullanilmaktadir. Today, the front wheels of the vast majority of passenger cars, some high-end or sports on both front and rear wheels of vehicles, in urban and intercity passenger transportation Various types of independent suspension systems in buses and midibuses, military vehicles types are used.

Konfor ve kontrol gereksinimlerinin sonucu olarak, yaylandirilmamis kütlenin mümkün oldugunca düsük tutulmasi, tasit süspansiyon sistemlerinin tasarimindaki temel beklentilerden biri haline gelmistir. Buna karsin, yük tasima kapasitesi ve üretiminin ucuzlugu nedeniyle, özellikle agir ticari tasit uygulamalarinda, genellikle sabit dingil genis bir kullanim alani bulmaktadir. As a result of comfort and control requirements, unsprung mass is possible. keeping it as low as possible is one of the main expectations in the design of vehicle suspension systems. has become one. However, due to its load carrying capacity and cheapness of production, Especially in heavy commercial vehicle applications, the fixed axle is generally used in a wide range of applications. finds.

Mevcut teknikte kullanilan sabit dingil uygulamalarinda bagimsiz süspansiyon sistemlerine oranla daha yüksek olan yaylandirilmamis kütle, yolculuk konforunu ve tekerlek-yol temasini, dolayisiyla seyir dinamigini olumsuz etkilemektedir. Independent suspension systems in fixed axle applications used in the current technique unsprung mass, ride comfort and wheel-road contact, therefore, it affects the navigation dynamics negatively.

Mevcut teknikte sürüs boyunca ortaya çikabilecek tasit gövdesi hareketlerine karsin, iz genisligi ve kamber açisinin mümkün oldugunca sabit kalmasi, agir ticari tasitlar için binek tasitlara göre çok daha büyük bir öneme sahiptir. Söz konusu iki büyüklügün sabit kalmasi, tekerlek asinmasinin, yuvarlanma direncinin ve yakit sarfiyatinin en düsük düzeyde tutulmasina, dolayisiyla tasitin servis ömrü boyunca daha ekonomik kullanilmasina olanak saglar. Despite the vehicle body movements that may occur during the ride in the current technique, the track width and that the camber angle remains as constant as possible, for heavy commercial vehicles compared to passenger vehicles is of much greater importance. Remaining constant of the two dimensions in question, the wheel keeping wear, rolling resistance and fuel consumption to a minimum, therefore, it allows the vehicle to be used more economically throughout its service life.

Süspansiyon sistemi olarak sabit dingillerin seçilmesi, bu ihtiyaca büyük ölçüde cevap vermekle birlikte, titresim transferi ve dolayisiyla gürültüye bagli çesitli problemleri de beraberinde getirmektedir. The choice of fixed axles as the suspension system responds to this need to a great extent. However, it also brings with it various problems related to vibration transfer and therefore noise. brings.

Mevcut teknikte çekici ve otobüslerin sabit dingilinde tekerlegin biri kasisten veya çukurdan geçerken diger tekerlek de etkilenir. Bu nedenle özellikle bozuk yol ve viraj kosullarinda yol tutus kabiliyeti azalir. In the current technique, one of the wheels on the fixed axle of tractors and buses comes from a bump or a pit. while passing, the other wheel is also affected. For this reason, especially in rough road and cornering conditions, the road grip is reduced.

Mevcut teknikte kullanilan sabit dingil, yapisi itibariyle agirdir. Bu agirligin neden oldugu atalet kuvvetleri yine özellikle bozuk yollarda tekerlek-yol temasinin kesilmesine neden olur. Bu durum Özellikle yüksek hizla dönülen virajlarda tekerleklerin çok küçük sürelerde olsa bile yolla temasinin kopmasina ve yol tutus kabiliyetinin olumsuz etkilenmesine neden olur. The fixed axle used in the present technique is heavy in nature. The inertia caused by this weight forces cause the wheel-road contact to be cut off, especially on rough roads. This situation Especially in high-speed corners, the wheels can be driven even for very short periods of time. It causes the contact to break and the road holding ability to be negatively affected.

Sonuç olarak, mevcut teknikte yukarida belirtilen problemlerin iyilestirilmesi kapsaminda bagimsiz süspansiyon sistemlerinin avantajlari vardir. Özellikle binek araç ve otobüs uygulamalarinda yaygin olarak kullanilmaktadir. Ancak kamyonlar için bu avantaji saglayacak hidropnömatik süspansiyonlu ön dingil sistemine duyulan gereksinim ve mevcut çözümlerin yetersizligi, ilgili teknik alanda bir gelistirme yapmayi zorunlu kilmistir. As a result, within the scope of improving the above-mentioned problems in the current art, Independent suspension systems have their advantages. Especially passenger cars and buses widely used in applications. However, it will provide this advantage for trucks. The need for a hydropneumatic suspension front axle system and the existing solutions Inadequacy has made it necessary to make a development in the relevant technical field.

Sekil- 1, sekil- 2, sekil- 3, sekil- 4 ve sekil- 5'de bulus konusu hidropnömatik süspansiyonlu bagimsiz ön dingil sistemi gösterilmektedir. Kamyonlar için hidropnömatik süspansiyonlu bagimsiz ön dingil sistemi olup, tekerlegin araç sasisine enine yönde yerlestirilmis iki adet kolla (üst salincak (110) ve alt (170) salincak) baglandigi bir sistemdir. Tekerlege gelen kuvvet ve momentlerin karsilanabilmesi için alt salincak (170) tekerlek merkezinin altinda, üst salincak (110) ise üstünde olacak sekilde konumlandirilmaktadir. Burada üst salincak (110), alt salincaga (170) göre daha kisadir. Bunun nedeni yaylanma sirasinda iz genisligi ve kamber açisi degisiminin azaltilmasi ve sikisma yaylanmasi durumunda tekerlegin negatif kamber almasini saglayarak yanal kuvvet tasima kapasitesini arttirmaktir. Yön verici üst (110) ve alt (170) salincaklarin baglanti noktalari süspansiyon sisteminin kinematik özelliklerini belirler. In figure-1, figure-2, figure-3, figure-4 and figure-5, the subject of the invention is hydropneumatic suspension. The independent front axle system is shown. with hydropneumatic suspension for trucks It is an independent front axle system, with two arms placed transversely to the vehicle chassis of the wheel. (upper swing arm (110) and lower swing arm (170)) is a system to which it is connected. The force acting on the wheel and The lower wishbone (170) is below the wheel center to accommodate the torques. (110) is positioned to be above it. Here, the upper swing arm (110) is connected to the lower swing arm (110). It is shorter than (170). This is because of the track width and camber angle during springing. the wheel to receive negative camber in case of reducing the displacement and compression spring. It is to increase the lateral force carrying capacity by providing Directional top (110) and bottom (170) The attachment points of the wishbones determine the kinematic properties of the suspension system.

Bahsedilen kinematik özelliklerden baslicalari kamber ve kaster açilari (veya kaster mesafesi), dingil pimi (190) egim açisi, yön verme yuvarlanma yariçapi, yalpa merkezleri ve yalpa ekseninin konumlari olarak siralanabilir. Bagimsiz ön dingil sisteminin yapisi geregi yaylanma sirasinda bu degerlerden bazilari degismektedir. ucuna ve alt ucuna monte edilmektedir. Hidropnömatik süspansiyon (200), süspansiyon tasiyiciya (140) baglidir. Titresim sönümleyici ve yay damper modülü olarak çalisir. Tüm tekerlekler üzerinde tamamen dengelenmis mükemmel bir yük dagilimi saglar. Süspansiyon tasiyici (140), dingil pimi (190) araciligiyla aksona (150) siki olarak baglanir. Süspansiyon tasiyici (140) ile dingil pimi (190), süspansiyon tasiyiciyi (140) dönme eksenine sabitleyecek ve dingil piminin (190) dönmesini engelleyecek sekilde saplama (210) ile montaj edilir ve sistem güvenligi saglanir. Sistem, aksonun (150) dingil piminin (190) ekseni etrafinda kontrolsüz bir sekilde dönüsünü engelleyen tahdit civatasina (220) sahiptir. Bunun ötesinde, hidropnömatik süspansiyon (200) ile aracin sürüs yüksekligi, degisken yükleme kosullari, yol kosullari, rüzgar ve engebeli araziler için ayarlanabilir. The main kinematic features mentioned are camber and caster angles (or caster distance), axle pin (190) pitch angle, steer roll radius, roll centers and roll can be listed as the positions of the axis. Springing due to the structure of the independent front axle system Some of these values change during It is mounted at the end and the lower end. Hydropneumatic suspension (200), suspension attached to the carrier 140. It works as a vibration damper and a spring damper module. All It provides a perfectly balanced load distribution on the wheels. Suspension The carrier 140 is rigidly connected to the axon 150 via the axle pin 190. suspension carrier The axle pin (190) with 140 will fix the suspension carrier 140 to the axis of rotation and the axle It is mounted with a stud (210) in such a way as to prevent the pin (190) from turning and the system security is ensured. The system rotates around the axis of the axle (150) of the pivot pin (190). It has a stop bolt (220) that prevents its rotation. Beyond that, hydropneumatic suspension (200) and the vehicle's ride height, variable loading conditions, road conditions, wind and adjustable for rough terrain.

Bu sistemde üst salincagin (110) aksona (150) baglandigi noktada küresel dönme hareketine izin verebilecek mafsallara ihtiyaç vardir. Bu baglanti için küresel mafsal - rotil (120) kullanilmaktadir. Rotil (120) kullanilmasinin nedeni, maksimum iç tekerlek yönlendirme açisi 45° de, fren grubu (160) konumunun silindirik mafsal baglantisina imkân vermemesidir. Ayni sebepten üst salincak (110) kolu tasarimi tek taraftan baglanmaktadir. Rotil adaptörü (130) ise rotilin (120) aksona (150) baglantisini saglayan özel bir baglanti elemanidir. In this system, at the point where the upper swing (110) connects to the axon (150), it has a spherical rotation. joints that can allow are needed. Ball joint for this connection - ball joint (120) is used. The reason for using ball joint (120) is the maximum inside wheel steering angle. At 45°, the position of the brake group (160) does not allow the cylindrical joint connection. Same For this reason, the upper control arm (110) arm design is connected from one side. If the ball joint adapter (130) It is a special connection element that provides the connection of the ball joint (120) to the axon (150).

Yapilan tasarim geregi süspansiyon elemani direkt olarak akson (150) ile temas halinde oldugundan üst (110) ve alt (170) salincak düsey kuvvet tasimamaktadir. Bu sayede salincaklar üzerinde ilave bir egilme olusmaz. Çalisma esnasinda üst salincak(110), yan kuvvet ve fren grubundan (160) gelen fren kuvvetleri altinda egilmeye ve burulmaya zorlanmaktadir. Bu nedenle salincagin kesiti egilmeye ve burulmaya mukavim l profil formundadir. By design, the suspension element is in direct contact with the axon (150). Since the upper (110) and lower (170) swings do not carry vertical force. In this way, they will swing No additional bending occurs on it. During operation, upper swing arm (110), side force and brake It is forced to bend and twist under the braking forces coming from the group (160). This Therefore, the cross section of the swing is in the form of a profile that is resistant to bending and twisting.

Alt salincak grubu, alt salincak (170) ve salincagin dingil pimine (190) baglantisinda kullanilan perno (230), konik makarali rulmanlar (240), rulman mesafe halkasi (250), keçe çalisma bilezikleri (260), nutringler (270) ve çektirme somunu (280) parçalarindan olusur. Alt salincagin (170) dingil pimi (190) ile baglantisi, üst salincaktan farkli olarak iki adet konik makarali rulman (240) kullanilarak yapilmaktadir. Bunun nedeni alt salincaga (170) özellikle viraj dönüsü durumunda tekerlek dinamik radyusunun yarattigi momentten dolayi gelen yüksek kuvvetlerdir. Rulmanlar (240) komple dönme hareketi yapmayip, aski sistemi ile birlikte yol bozukluklari nedeniyle salinim hareketi yaparlar. Bu sayede yükün her zaman ayni noktaya gelmesi ve rulmanin (240) saglikli çalismasini bozan deformasyonun olusmasi engellenir. The lower wishbone assembly is used to connect the lower wishbone (170) and the wishbone to the axle pin (190). pin (230), tapered roller bearings (240), bearing spacer (250), seal run rings (260), nutrings (270), and extractor nut (280) parts. bottom swing The connection of (170) with the axle pin (190) is different from the upper wishbone, two tapered roller bearings. (240) using . This is due to the lower swing arm (170), especially when cornering. high due to the moment created by the wheel dynamic radius are forces. Bearings (240) do not make complete rotational movement and travel together with the suspension system. They make oscillating movements due to their disturbances. In this way, the load is always at the same point. and the formation of deformation that disrupts the healthy operation of the bearing (240) is prevented.

Burada poyra (180) içine monte edilen rulmanlar ilejant arasindaki baglanti saglanir. Here, the connection between the bearings mounted in the hub 180 and the rim is provided.
