Setting the minimum thickness of brake pads with the increasing plots of nonstop trains are and protracted descent
In the car sector is carried out systematic work to increase the warranty sections of non-stop the trains. The lengths of these segments are different and reach 250-300 km. A constraint on this length, is the work of the axle boxes sliding freight cars.
Upon completion of the transfer of freight wagons on roller bearings parts non-stop distance can be increased up to 500-600 km (taking into account the organization trains and working conditions of locomotive crews).
Brake pads should have a thickness more than the minimum standards set for prosledovaniya to the next PTO.
Uniform standards set by the Regulations on the operation of the brakes (12 mm - cast iron block wagon-type, 10 mm - phosphorus stocks in the railcar, 15 mm - on locomotives, 14 and 10 mm - composite blocks, respectively with a steel back and setchatoprovolochnym frame), not in all cases, cast-iron shoes meet specific operating conditions. Therefore allowed the introduction of local regulations on the basis of experienced travel more than the minimum thickness of cast-iron shoes for the truck loaded wagons. For passenger and freight empty wagons this question usually arises in connection with bilateral inhibition of passenger cars and smaller brake pressing empty cargo.
Minimum thickness of composite brake pads ensures their work in virtually all operating conditions.
The thickness of the brake pads checked from the outside, and when wedge wear - at a distance of 50 mm from the thin end. By explicitly wear on the inside, if this wear can cause damage to the shoe, shoe replaced.
