Product Description



Train and Wagon Cast Iron Brake Block

According to customers` drawings, for train or wagon

Heavy Duty Truck.Train.Bus,Automobile,petroleum drilling machine.

Cast iron HT200

Composite material

Refer to standard GB/T 9439-1988

1.rail way composite Brake shoe Material:

Composite material, high friction composite brake shoe, low friction composite brake shoe

2.Advantage:

--Composite friction material bearing high energy braking;

--High coefficient of friction and stability,

--small heat fade for coefficient of friction,

--Temperature insensitiveness,

--Develop according to the samples or drawings

--Certification:ISO9001-2000

4. The HGM - A high friction composition brake shoe steel back and friction body two parts.

Brake shoe shape size (mm) :

(1) the steel back of outer arc: R450

(2) brake shoe width: 820-1

(3) the thickness of the brake shoe: 45

5. The steel back is made of Q235A steel manufacturing, steel plate performance shall comply with the provisions of GB/T700.

6. Brake shoe is made up of steel back and friction.Friction main raw material for: phenolic resin, nitrile rubber, steel fiber,

reduced iron powder, graphite, etc.

7. The friction performance component of the learning performance and friction wear performance of two parts.

The mechanical properties shall comply with:

Table 1 physical and mechanical performance of the brake shoe

Unit performance indicators

G/cm3 density less than nominal worth plus or minus 5%

The compression strength of 25 Mpa or greater

The impact strength acuity 2.0 kJ/m2

The compression modulus of Mpa to 1.3 * 103 or less

Rockwell hardness (HRR) 90 or less

Water absorption percentage < 1.5%

Oil absorption percentage < 1.5%

Brake friction wear performance should be consistent with:

Table 2.The change of the instantaneous friction coefficient range (20 kn brake shoe pressure)

Speed (km/h) 0 10 20 30 to 40 50 to 60

The maximum 0.63 0.602 0.558 0.546 0.515 0.482 0.471

Standard 0.48 0.46 0.43 0.42 0.39 0.37 0.36

The minimum 0.42 0.40 0.40 0.36 0.33 0.32 0.37

It suitable for metro, inter-city trains, railway vehicles,

good strength and long life, temperature insensitiveness,

good performance of heat, samll heat fade for coefficient of friction
