The current state-of-the-art braking system for freight trains are disc brakes, where the brake crown is made of one piece. The main problem of the current state-of-the-art solution is: when replacing the non-divided brake discs, one must remove the complete axle and other mechanical parts on it, such as bearings, wheels and hubs, which causes high maintenance costs of disc brakes. Additionally, while dismantling the discs, mechanical parts can be damaged, because they are connected by press fit, which is usually dismantled by using force.
The developed DRFB brake discs are divided. The crown of the disc is made of two parts, bolted together with self-developed bolts. There is no need to dismantle the axle and other mechanical parts (bearings, wheels, hubs); one only needs to replace the brake crown, which enables a considerably easier and cheaper assembly/dismantling and influences the decrease of LCC.
Results of the FUTURA project have influenced academic, science and research institutions, suppliers, competitors and customers. The most important channel used for communication with relevant stakeholders were face-to-face dialogues and fairs.
Some impacts of the FUTURA project:
• Economic impact is achieved through safer, more secure, cheaper and faster rail fraight transport.
• Social impact is achieved through improved safety (due to reduction of braking distance) which will result in fewer accidents. Due to lower noise and vibrations level, the human health and quality of life will improve.
• Environmental impact is achieved through lower noise and vibration level and shorter braking distance, which has positive influence also on transport of dangerous goods.
• R&D results can be transferred to the automotive, chemical, electro, metal processing and similar industries.
