“…According to authors of papers [8] and [9], a friction film or a third body layer is produced incessantly by maintaining a certain thickness and it is composed of carbonaceous reaction products, unreacted constituents, oxide from metallic ingredients. Friction characteristics of the transfer layer between a brake disc and pads developed during subsequent braking influence the braking effectiveness at elevated temperature.…”

The paper concerns evaluation of the coefficient of friction characterising a friction couple comprising a commercial brake disc cast of flake graphite grey iron and a typical brake pad for passenger motor car. For the applied interaction conditions, the brake pressure of 0.53 MPa and the linear velocity measured on the pad-disc trace axis equalling 15 km/h, evolution of the friction coefficient μ values were observed. It turned out that after a period of 50 minutes, temperature reached the value 270°C and got stabilised. After this time interval, the friction coefficient value also got stabilised on the level of μ = 0.38. In case of a block in its original state, stabilisation of the friction coefficient value occurred after a stage in the course of which a continuous growth of its value was observed up to the level μ = 0.41 and then a decrease to the value μ = 0.38. It can be assumed that occurrence of this stage was an effect of an initial running-in of the friction couple. In consecutive abrasion tests on the same friction couple, the friction coefficient value stabilisation occurred after the stage of a steady increase of its value. It can be stated that the stage corresponded to a secondary running-in of the friction couple. The observed stages lasted for similar periods of time and ended with reaching the stabile level of temperature of the disc-pad contact surface.

“…One of the most important braking phenomena is different sensitivity of braking torque against change of actuation pressure, sliding speed and brake interface temperature. Besides, the properties of the friction material play often a crucial role in driver's perception of braking performance, especially at elevated brake interface temperatures [8][9][10]. Widespread opinion relates to drivers, who expect relatively constant level of brake performance at various braking regimes.…”

“…Bijwe ve arkadaşları [18], 300-400ºC arasındaki sıcaklık değerlerine yükselen fren disklerinin etkinlik kaybına neden olabileceğini vurgulamışlardır. Aleksendric ve Duboka [19] ise 400ºC civarındaki sıcaklıkların eşik değer olduğunu, disk sıcaklıklarının 600ºC'yi aşması halinde fren diski ile balata arasındaki sürtünme katsayısının büyük ölçüde azalması nedeniyle fren etkinliğinin tamamen kaybolacağını savunmuştur. Benzer sıcaklık eşik değerlerini telaffuz eden Lingman da [20] 900ºC'ye ulaşan disk sıcaklıklarının balatanın yanmasına neden olacağını belirtmiştir.…”

ÖZETBu deneysel çalışmada, fren disk sıcaklıklarındaki artışın taşıtın frenleme performansına etkileri araştırılmıştır. Bu amaçla, frenleme performansının en önemli göstergesi olan durma mesafesi testleri yapılmıştır. Testler, bir hafif ticari taşıtta, değişik disk sıcaklıkları, pedal kuvvetleri, taşıt yükleri ve başlangıç hızlarında gerçekleştirilmiştir. Yapılan fren etkinliği test sonuçları, fren disklerindeki sıcaklık artışının taşıtın frenleme mesafesini olumsuz etkilediğini göstermiştir. Farklı pedal kuvvetleri, frenleme başlangıç hızları ve taşıt yükü değişimlerine göre değerlendirilen sonuçlardan, disk sıcaklığındaki artışın frenleme mesafesini artırdığı gözlenmiştir. Tipik bir yol testi sonucu olarak; 80 km/h hızla ve maksimum pedal kuvvetiyle 63ºC fren disk sıcaklığında taşıt 44,9 m'de dururken, 298 ºC disk sıcaklığında durma mesafesi %17,4 oranında artarak 52,71 m olarak ölçülmüştür.Anahtar kelimeler: Frenleme performansı, yol deneyi, durma mesafesi, disk sıcaklığı, hafif ticari taşıt THE EFFECT OF BRAKE DISC TEMPERATURE ON BRAKING PERFORMANCE ABSTRACTIn this experimental work, effect of increasing in brake disc temperature on braking performance was investigated. For this purpose, braking distance tests which the criteria of braking performance were carried out. The tests were conducted on a small-size commercial vehicle for different disc temperatures, pedal forces, the vehicle loads and for initial vehicle speeds. Test results of stopping (braking) distance were analyzed for the variation of disc temperatures. The results showed that the stopping distance is considerable increased when the disc temperature is increased for different vehicle speed and pedal forces. Typically, at the vehicle speed of 80 km/h and maximum pedal force for 63 ºC disc temperature, 44.9 m stopping distance was measured. When the temperature is increased as 298 ºC, stopping distance is increased as 52.71 m with the rate of 17.4% at road test.
