Installation steel backing for powder metallurgy brake pad of rapid train

Abstract

The invention relates to installation steel backing for a powder metallurgy brake pad of a rapid train. The installation steel backing is characterized by comprising a boss, a spherical groove, a brake pad connecting piece passing hole and a fastener groove. The appearance of the boss is circular and the boss is higher than a steel backing basal plane by 3-5mm. The installation steel backing is characterized by also comprising a flow guide rib, and the flow guide rib is arranged in the middle of the boss and is positioned on a circle concentric with inner and outer arcs of the steel backing. The flow guide rib is equal to the boss in height. With the installation steel backing for a powder metallurgy brake pad, a clearance is remained between the brake pad and the installation steel backing, thereby being beneficial to heat dissipation of the brake pad during braking, and reducing the temperature of the brake pad and a brake disk. As the flow guide rib is formed, air can be forced to convect between the brake pad and the installation steel backing, thereby being more beneficial to the temperature reduction of the brake pad and the brake disk. Therefore, the installation steel back has huge advantages in prolonging the service life of a brake system and realizing safe driving.

Description

technical field [0001] The invention relates to a steel back for installing powder metallurgy brake pads of high-speed trains, belonging to the field of train braking systems. Background technique [0002] Powder metallurgy friction material is a composite material made by powder metallurgy with metal and its alloy as the matrix, adding friction components and lubricating components. Powder metallurgy friction material has the advantages of sufficient strength, suitable and stable friction coefficient, stable and reliable operation, wear resistance and less pollution, and is one of the most widely used materials in the modern brake material family. [0003] With the rapid development of our country's economy and the rapid increase of railway passenger and cargo transportation, the high-speed railway transportation has become an inevitable development trend. At present, my country has opened high-speed trains with a speed of more than 300km per hour. The high speed of train...
