“…The changes of all these parameters which are of great importance for tyre mechanics depending on the axle load were investigated. The dynamic load distribution on vehicle axles is constantly changing due to some reasons such as braking, acceleration, and road slope [40]. Therefore the force, torque, and slip values observed in each wheel are different from each other.…”

Bu çalışmada, taşıt güvenlik ve kontrol sistemlerinin işletilmesinde önemli bir parametre olan kayma açısı matematiksel olarak incelenmiştir. Fiala lastik modeli temel alınarak oluşturulan matematiksel model ile aks yükünün 1000 N ile 6000 N arasındaki değerleri için yanal kuvvet ve kendini ayarlama torkunun kayma açısına bağlı değişimi belirlenmiştir. Bu parametreler ile pnömatik iz mesafesi, temas alanı basınç dağılımı, temas alanı maksimum basınç değeri, yanal lastik sapması ve viraj rijitliği değerleri hesaplanmıştır. Benzer şekilde kamber açısının belirli değerleri için ise kamber itki kuvveti ve kamber rijitliği değerleri incelenmiştir. Lastik mekaniği için büyük önem arz eden tüm bu parametrelerin aks yüküne bağlı olarak değişimleri araştırılmıştır. Çalışmada 205/55R16 ebatlarındaki standart bir pnömatik lastiğe sahip tek bir tekerlek örneği, kuru asfalt yol şartlarında, esnek tekerlek-rijit zemin yol etkileşimi açısından araştırılmıştır.

<div class="section abstract"><div class="htmlview paragraph">Load-carrying transportation has recently increased due to cargo and online home shopping. As a result, there is a growing demand for vehicles that can pass through narrow streets and carry loads for short distances. Electric vehicles are vital in the automotive industry due to their zero emissions and further promotion through new regulations. This study is focused on determining the spring coefficients of helical springs for a micro-truck vehicle, which will be used for cargo transportation and has a leaf spring with a specific spring coefficient on the rear axle and an independent double wishbone suspension system on the front axle. In addition to being vehicles with low weight values, micro-trucks have the axle capacity required for urban transportation due to their low track width and dimensions. Correctly determining the leaf spring is essential as it will directly affect the loads on the suspension system, wheel life, energy consumption, and comfort level. When determining the spring coefficient, it is essential to decide on the bounce, pitch, and ride frequency values and evaluate the vehicle’s bump passing and comfort. In this context, along with theoretical calculations, quarter-vehicle, half-vehicle, and full-vehicle models were established, and the characteristics of the front suspension and the whole vehicle were determined.</div></div>
