Özet:

 In the trials of the present work, a double-axle trailer with a carrying capacity of 6 tons and a hydraulically effective mechanical brake were used as a tractor towed car. There is a hydraulic brake system on each axle of the agricultural trailer. In order to separate the brake system on the axles from each other, a hydraulic mechanically controlled 22 directional control valve was mounted on both hydraulic brake system inlets. The study was carried out at constant speed 25 km h-1, on stabilized road conditions, with 4 different braking modes and 4 different trailer loads. On stabilized ground, the braking acceleration deceleration of the tractor without trailer is 5.51 m s-2. The braking acceleration of the combination is 2.15 m s-2 under the condition that the trailers carrying capacity was 30 more loaded and without brakes, and the braking acceleration of the combination was 3.26 m s-2 when braking on both axles 4 wheels. The deceleration of the combination was above 3.5 m s-2 under the condition of braking on both axles at the rated load of the agricultural trailer, while it was below the standard value in other braking approaches.

 Bu çalışmadaki denemelerde 6 ton taşıma kapasiteli çift dingilli, hidrolik etkili mekanik frenli ve traktörle çekilir römork kullanılmıştır. Tarım römorkunun her iki dingiline de hidrolik fren sistemi bağlanmıştır. Dingillerdeki fren sistemini birbirinden ayırmak amacıyla, her iki hidrolik fren sistemi girişine birer adet hidrolik mekanik kumandalı 22 yön kontrol valfi monte edilmiştir. Çalışma sabit hızda 25 kmh-1, stabilize yol koşullarında, 4 farklı frenleme şekli ve 4 farklı römork yükünde yürütülmüştür. Stabilize zeminde sadece traktörün römorksuz frenleme ivmesi 5.51 ms-2 olarak bulunmuştur. Römorkun taşıma kapasitesinin 30 daha fazla yüklü olduğu ve frensiz olduğu koşulda kombinasyonun frenleme ivmesi 2.15 ms-2, her iki dingilde 4 tekerlekte frenlenme yapıldığı koşulda ise kombinasyonun frenleme ivmesi 3.26 ms-2 olmuştur. Kombinasyonun frenleme ivmesi, tarım römorkunun anma yükünde her iki dingilde frenleme yapılması koşulunda 3.5 ms-2 üzerinde iken diğer frenleme uygulamalarında standartlardaki referans değerin altında kalmıştır.
