Developed Brake Pads for Domestic Trains

Brake for Trains Native Produce Improved: 1988 abroad since it made the high cost of production in Turkey imported composite brake shoe, completely produced locally with the support of TUBITAK.
With the invention of steam locomotives, cast iron (peak) brake pads have been started to be used for braking of trains on railways from 1860. Cast iron brake shoes are replaced by 20. From the middle of the century began to receive composite brake shoes. The light weight of the composite brakes, noise reduction, non-sparking, low wear rates and long life have extended the use. imported from abroad made for the production of brake system in Turkey, TUBITAK MAM Materials Institute, TCDD, was fully come to life through domestic production and the private sector in collaboration with TULOMSAS. The project coordinator of the system Mehmet Gunes, produced by a few countries in the world that they are proud to produce these shoes domestic, he said.
of composite lining in Turkey's railways xnumx'l that was imported from abroad since the year due to the superior features and increasing the use of almost all trains used in describing the Sun, "TCDD's annual demand of about 90 thousand brake shoe. Turkey's railway transport is also one of the 300 goals. When this situation is taken into consideration, it is expected that the need for the brake paper will reach millions in the coming years. Bu
Two years of planning, the end of 3 years in R & D activities, explaining that Turkey's first indigenous capabilities with managed to develop a composite brake system the sun, this gave the following information about the technology: "Turkey was not manufactured solve somehow this technology until the end of the study. Several attempts were made, but somehow did not succeed. However, our last work consists of a combination of twenty different materials and a composite brake shoe of domestic production. 20'ların performance increase, extending the service life of up to six months, lightness, quiet operation and low cost of the imported products because of the advantages.
"All these returns, as well as the world with a very large market share and production of brake shoes can be made by only a few countries to export abroad will be a significant contribution to the economy," he said.
Knob: ”Brake System in European Standards Top
One of the consultants of the project, lecturer at Yildiz Technical University Dr. ahmet Turkey Knob in the composite brake system in Turkey in terms of the project to demonstrate the feasibility stressed the importance locally.
Composite brakes, different abrasives, lubricants, reinforcing elements, which consists of many components, describing Topuz, "Our country, can be produced locally and has a brake in the European standards," he said.
Title: ir Train Equals Brake:
TCDD Branch Manager Mustafa Eser said that the railroads ın train equals brake, outweighed the opinion that the train has a more important position than the speed at which it will stand.
The work reported that the TCDD required a high workforce because it only allocated a large number of its staff to replace the cast iron brake shoes every two to three days, and at the same time the costs of these brakes were very high.
TCDD's composite brake technology widely used in the world, 1988, E8000 and E14000 type of commuter trains in the work that began, the 10 years, they said they are investigating the feasibility of these brakes with domestic facilities.
Eser said that they started planning a comprehensive scientific study about five years ago. Fren In order to implement these brakes on a train, a long-term R & D study was required. First we started with a wheel. Then we successfully completed field tests with bogie, wagon and full train set. After the field tests, the project, which was successfully completed with the support of TUBITAK, was transferred to the industry and the mass production of the train brake pads started.
Title: göre 75 is lighter than peak brake shoes Eser
The work gave the following information on the superiority of the domestic production composite brakes:, The corrosion resistance, heat, sound and electrical insulation of fiber reinforced composite materials provide an advantage for their respective applications. The tensile and bending strength of composites is much higher than many metallic materials. Composites do not suffer from low and high temperature weather conditions, corrosion and most chemical effects. Wheel wear is very small compared to peak brake shoes. 75 is lighter than peak brake shoes. It reduced the workmanship and friction and increased the working time of the wagons. Composite brake shoe component will affect human health negatively; asbestos, lead, zinc or other harmful elements are not used as metallic or compound. Composite brake pads do not cause signaling, electrification and electrical faults in locomotives caused by iron brake pads of the peak brake shoe. Ozit
The work started by replacing 8-12 in ore wagons, 12-14 in bojili cargo wagons and 8-12 in passenger wagons in the 30-35 month by passing the composite braking system. Millions of dollars saved around, milyon he said.
