With increasing car ownership in our country, the production of brake pad is also increasing year by year. Brake pads is
the key components of train brake system. The quality of the high-speed rail brake pads is directly related to the train
speed can slow down and stop in time, called “the patron saint of life”.
With the rapid development of high-speed railway in China, its various performance requirements also corresponding
increase, especially puts forward more strict requirements on braking performance. The braking power and speed of the
train is cubic relationship, that is to say, the train speed double then braking power requires increased 8 times. High-speed
train braking force mainly include electric braking force and friction, the friction braking is train safe parking final
guarantee. Friction braking force comes from the friction between the brake disc and brake pads on the braking system.
And in the braking system brake pads performance has very big affect on the train braking effect. Brake pad materials at
home and abroad mainly experience metal, alloy and powder metallurgy etc.
In the world there is only a few countries such as Germany, France and Japan can produce high-speed train brake pad.
Among them Germany Knorr company Monopolies more than 80% of the global high iron brake pads market. High-speed
trains in China since its opening, the brake pads of braking system relies on imports for long-term. Import brake pads has
problems aush as high price, long cycle of supply, spare parts supply not in time and poor after-sales service. High-speed
rail brake pads is n technology protection period before 2012, has been importing foreign products. In recent years the
domestic represented by Tianyishangjia and PuRan private enterprises gradually enter the field of high-speed rail brake
pads. Tianyishangjia in September 2013 got seven models 5 types of brake pads CRCC certificate of railways product,
PuRan got CRCC certification in 2014. In 2015, BoShen tool has finished the high-speed train brakes 1:1 brake friction
wear performance test.
