EMU brake system introduction

The main contents of the EMU brake system include the basic concept of braking, brake classification, EMU brake system control device, EMU taxi control device, EMU electric brake, EMU friction brake and device, and domestic EMU. (CRH2 and CRH5 EMU) The composition, working principle and characteristics of the brake system, also briefly introduced the EMU brake system test and common fault handling and new brake technology. Since the sixth major speed increase of China's railways on April 18, 2007, and the first time the 200 km speed trains in China, the CRH series EMUs, collectively known as the “Harmony”, have become the symbol of China's railways entering the high-speed railway club. . During the "Eleventh Five-Year Plan" period, China will build a new railway line of 17,000 km with a total investment of 2 trillion yuan. According to the newly adjusted national medium- and long-term railway network plan, by 2020, the national railway operation mileage will reach 120,000 km, and the “four vertical and four horizontal” railway express passenger transportation channels and the intercity passenger transportation system with economically developed and densely populated areas will be built. This will provide a further stage for the CRH series of EMUs.
