THE DISC BRAKE. A CONTRIBUTION TOWARDS THE STUDY OF ITS RATIONAL USE ON RAIL VEHICLES

From the point of view of their conventional methods of production, and given the same wheel diameters, the disc brake enables, in the case of braking to a stop, a greater amount of energy to be dissipated than does a cast-iron brake block. There exists, therefore, a field, which is that of high speeds and heavy axle loads, in which the use of the disc brake is more appropriate than of the brake block. It is, however, difficult to define where precisely the limits of this field lay, as they also depend, in fact, on the braking performance, i.e. the average rate of deceleration required and, therefore, on the signalling system used. The brake lining pads play an outstanding part. The results which can be expected from a disc brake depend, in the first place, on the lining pads, which should be capable of satisfactory performance, both when the temperature is high, and under special atmospheric conditions (low temperatures, and considerable humidity).
