Completely Indigenous Brake for Trains Improved: production done abroad since 1988 that the high cost of imported composite brake shoe in Turkey, was completely produced locally with the support of TUBITAK.
From the 1860s with the invention of steam locomotives, cast iron (pig) brake shoes were used to allow the trains to brake on the railways. Cast iron brake shoes were replaced by composite brake shoes from the mid-20th century. The lightness of composite brakes, reducing noise, not creating sparks, low wear rates and long life have made it more common. 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. Providing information about the system, the project executive Dr. Mehmet Güneş stated that they are proud to produce these shoes, which can be produced by several countries in the world, locally.
Turkey's railways is increasing the use of composite pads imported from abroad by explaining that since the 90s and the sun used on virtually all trains because of its superior properties, "TCDD annual brake shoe needs around 300 thousand pieces. Turkey's 2023 targets include railways in the transport. Considering this situation, the need for brake shoes is expected to reach millions in the coming years. ”
Two years of planning, 3 years in R & D activities at the end explaining that managed to develop a composite braking system for the first time indigenous capabilities in Turkey sun, this gave the following information about the technology: "Turkey was not manufactured solve somehow this technology until the end of the study. Various attempts have been made, but somehow it has not been successful. However, the domestic production composite brake shoe, which has succeeded with our latest work, consists of twenty different materials coming together. It provides advantages over imported products due to its 20% performance increase, its lifetime up to six months, its lightness, quiet operation and low cost. ”
In addition to all these benefits, Güneş said, “The brake shoes, which have a huge market share in the world and which can only be produced by a few countries, can be made an important contribution to the economy by exporting abroad.”
Topuz: "European Standard Brake System"
Professor of Yıldız Technical University, one of the consultants of the project. Dr. ahmet Turkey Knob in the composite brake system in Turkey in terms of the project to demonstrate the feasibility stressed the importance locally.
Explaining that composite brakes are composed of many components such as different abrasives, lubricants, reinforcement elements, Topuz said, "Our country has a brake that can be produced locally and has European standards."
