Abstract

Željeznički promet vrsta je prometa koji se odvija kopnenim prostorom određenim linijama (prugama). Ima vrlo veliki značaj u putničkom i teretnom prometu. Danas nije više naglasak na izgradnji novih željezničkih pruga. One se grade u manjem obimu i to samo u onim dijelovima svijeta gdje treba kopnom osigurati jeftiniji prijevoz većih količina tereta u određenom pravcu. Puno više pažnje se pridaje modernizaciji željeznice. Jedna od bitnijih dijelova je sigurnost. U tome najbitniju ulogu imaju kočnice i kočni sustavi. Sa sigurnosne strane, vlak ne mora krenuti ali mora stati. U ovom radu su opisane vrste kočnica koje se danas koriste u željezničkom prometu, te je prema postojećoj strukturi kočnog sustava izvedeno dimenzioniranje kočnog polužja i napravljen kontrolni proračun za prazni i natovareni režim rada.

Abstract (english)

Railway traffic is a type of transport that takes place on land over certain routes (tracks). It has great significance in passenger and freight traffic. Today, there is no more emphasis on the construction of new railways. They are built in a smaller extent and only in those parts of the world where there is need to provide cheaper transportation of larger amounts of cargo in a certain direction. Much more attention is paid to the modernization of the railways. One of the most important parts is safety. The most important part of it are brakes and braking systems. From safety point of view, the train does not have to start but must be able to stop. In this paper are described types of brakes currently used in railway traffic and the dimensioning of the brake mechanism is performed according to the existing structure of the braking system. Also a control calculation for the empty and loaded working regime of the freight car is made.
