Abstract

Many studies on tractive performance of tractor tires have been carried out to solve soil-wheel interaction problems in the last decades. The purpose of this study is to experimentally determine effects on tractive performance of radial and bias-ply drive tires at three different tire lug heights, axle loads and inflation pressures. The experiments were carried out in stubble field conditions. To obtain sufficient performance data, a new single wheel tester was designed and manufactured. Travel reduction, net traction ratio and tractive efficiency varied from 3.3% to 34.1%, 0.24 to 0.93 and from 0.27 to 0.78 respectively depending on drawbar pull. The effects of tire type, lug height, dynamic axle load and inflation pressure on tractive efficiency were found significant P

Bahçe Traktörlerinde Kullanılan Muharrik Lastiklerin Bazı Özelliklerinin Çeki Performansına Etkileri

Abstract

Yıllardır, toprak-tekerlek etkileşimi sorunlarını çözmek için traktör lastiklerinin çeki performansı üzerine birçok çalışma yürütülmüştür. Bu çalışmanın amacı, bahçe traktörlerinde kullanılan üç farklı profil yüksekliğine sahip radyal ve çapraz katlı muharrik lastiklerin çeki performansına, aks yükünün ve lastik iç basıncının etkilerini deneysel olarak belirlemektir.Denemeler anız tarla koşullarında yürütülmüştür. Belirtilen şartlar altında, yeterli performans verileri oluşturabilmek için, yeni bir tek tekerlek deney düzeneği tasarlanmış ve imal edilmiştir. Çeki kuvvetine bağlı olarak; patinaj değerleri % 3.3 ile % 34.1, net çeki oranı değerleri 0.24 ile 0.93 ve çeki verimliliği değerleri 0.27 ile 0.78 arasında değişmiştir. Yapılan varyans analizi ve LSD testi sonuçları; lastik tipi, profil yüksekliği, dinamik aks yükü ve lastik iç basıncının, çeki verimliliği üzerindeki etkisinin önemli olduğu göstermiştir P
