Construction and functional characteristics of rail vehicles brake elements

Tema ovog završnog rada je prikaz i opis konstrukcijskih i funkcionalnih značajki elemenata kočnica tračničkih vozila te primjer izračuna kočnice gospodarskog vagona. U uvodu su obrađeni temeljni pojmovi o kočenju, njihova gradbena struktura, pojedinačni elementi, konstrukcijski elementi i opis funkcionalnosti te povijest razvoja kočnica. Opisana je podjela kočnica prema načinu djelovanja i prema načinu upravljanja. Najveći prostor u ovom radu posvećen je pojmovima vezanim za smanjenje vozne brzine vlakova te izvršnom uređaju zračne kočnice, tj. rasporedniku. Detaljno je opisan Oerlikonov ESt-3f rasporednik koji je ugrađen u teretne vagone. Dan je opis tračničkih vozila prema vrsti pogona. Razvoj i modernizacija željeznica je konstrukcijski izazov, a u svezi sigurnosnog motrišta kočnice i kočioni sustavi te njihova funkcionalnost uz neupitnu pouzdanost predstavljaju izazov u konstrukcijskom smislu s obzirom na kontinuirano povećanje voznih svojstava.The theme of this bachelor thesis is a description of the construction and functional characteristics of the elements brake rail vehicles and the example of the calculation of the commercial wagon brakes. In the introduction are processed basic concepts of braking, their construction structure, individual and structural elements, description of functionality and history of brake development. The division is described according to the mode of activity and the mode of controlling. The greatest space in this work is devoted to terms related to reducing the speed of the trains, and the air brake control devise, as known as distributor. Oerlikon ESt-3f distributor is described in detail for all freight wagons. In addition, the description of the track vehicles is given by the type of the drive. The development and modernization of the railways is a structural challenge, with regard to the safety aspect of the brakes, braking systems and their functionality with unquestionable reliability represents a challenge in the constructional sense in view of the continuous increase of the driving characteristics
