China Brake Shoe Brake Block Rolling Stock Brake

1. Features:
a.The adjustablerange of friction coefficient , it is applicable to various running speeds.
b.Thecomposite brake shoe provideshigh abrasion resistance and long service life, so as to greatly reduce the workload of brake shoe replacement and save the costs of maintenance and operation.
c. Without sparks when braking, it can Switch avoid the iron powders generated during wear-and-tear andrelieve the impacts on electric equipment.
d. It is of light weight, so it can be replaced conveniently and easily.
e.It causessmall abrasion aPrinting Machinery nd no thermal crack on the tread.
f. Thelower friction coefficient at high speed maintains sufficient braking force, improves the braking performance and shortens the braking dMagnetic Material istance.
g. The friction coefficient index can be fully increased. The composite brake shoe is combined with the small-diameter braking cylinder to save compressed air. When braking on high slope areas continuously, it may shorten the air recharge time, so as to improve the wagon safety when running on high slope areas.
h.The composite brake shoe won't result in rough tread, so it could reduce the noise level by 8~10dB.2. Application:
Applicable for freight rolling stock speed at 90km/h, and axle load below 21t.3.
